Abstract

The present claims a decorating tool, comprising a working portion, a grip portion and a connecting portion. The working portion and the grip portion are connected to two ends of the connecting portion, respectively. The connecting portion is configured for controlling the grip portion to rotate towards or away from the working portion. The grip portion can be rotated to adjacent to a sidewall of the working portion, and not protrude from two ends of the working portion.

First claim

I claim:

1. A decorating tool, comprising a working portion, a grip portion and a connecting portion,
wherein the working portion and the grip portion are connected to both ends of the connecting portion, respectively;
the connecting portion is configured for controlling the grip portion to rotate towards or away from the working portion; and
the grip portion is rotatable towards or away from the working portion, wherein when the grip portion rotates to be adjacent to a sidewall of the working portion, the grip portion does not protrude from two ends of the working portion,
wherein the connecting portion comprises a second adjusting unit, and the connecting portion is connected to the working portion via the second adjusting unit, the second adjusting unit is configured for adjusting a working angle of the decorating tool;
the second adjusting unit comprises a clamping member, a second connecting shaft, and a second adjusting member, and the working portion further comprises a supporting portion in a tube shape; the clamping member is sleeved on an outer surface of the supporting portion and capable of rotating around an axial line of the supporting portion.

2. The decorating tool of claim 1 , wherein a first end of the connecting portion is connected to a middle part of the sidewall of the working portion, and a length of the grip portion is half a length of the side of the working portion.

3. The decorating tool of claim 1 , wherein the connecting portion has a locking state and an unlocking state,
wherein when the connecting portion is in the unlocking state, the grip portion is rotatable of rotating towards or away from the working portion; and
when the connecting portion is in the locking state, the grip portion is fixed to the working portion.

4. The decorating tool of claim 3 , wherein the connecting portion comprises a first locking portion, a second locking portion and a first adjusting unit, the first locking portion and the second locking portion are connected to the working portion and the grip portion, respectively, and the first adjusting unit is movably connected to the first locking portion and the second locking portion; and
the first adjusting unit at least has a first adjustable position and a second adjustable position, when the first adjusting unit is at the first adjustable position, the first locking portion and the second locking portion mesh with each other to define the locking state; when the first adjusting unit is at the second adjustable position, the first locking portion and the second locking portion do not mesh with each other to define the unlocking state.

5. The decorating tool of claim 4 , wherein the first locking portion is opposite to the second locking portion, a side of the first locking portion near the second locking portion is provided with a first set of teeth, a side of the second locking portion near the first locking portion is provided with a second set of teeth, which matches with the first set of teeth; and
the first adjusting unit comprises a first connecting shaft and a first adjusting member, the first connecting shaft penetrates through the first locking portion and the second locking portion; the first adjusting member is movably connected to the first connecting shaft, and capable of moving relative to the first connecting shaft, so that the first locking portion and the second locking portion can be tightly mesh with each other, resulting in defining the locking state, or the first locking portion can be separated from the second locking portion, and the locking state between the first locking portion and the second locking portion is released, resulting in defining the unlocking state.

6. The decorating tool of claim 5 , wherein the first adjusting member is sleeved on the first connecting shaft and threadedly connected to the first connecting shaft, the first adjusting member is capable of moving along an axial line of the first connecting shaft, so that the first locking portion and the second locking portion are tightly connected or separated from each other.

7. The decorating tool of claim 5 , wherein the first adjusting member is pivotally connected to the first connecting shaft, the first adjusting member comprises a first protrusion,
the first adjusting member is capable of rotating relative to the first connecting shaft and driving the first protrusion to push the first blocking portion and the second blocking portion, so that the first locking portion and the second locking portion can be tightly meshed with each other; or
the first adjusting member can drive the first protrusion to move away from the first locking portion or the second locking portion, so that the first locking portion is separated from the second locking portion.

8. The decorating tool of claim 7 , wherein the first adjusting unit further comprises a first elastic member, the first connecting shaft comprises a plug portion and a first limiting portion which is connected to an end of the plug portion, an outer diameter of the first limiting portion is larger than that of the plug portion; and a first end of the first elastic member abuts against the first limiting portion, and a second end of the first elastic member abuts against the first locking portion or the second locking portion.

9. The decorating tool of claim 8 , wherein the first adjusting unit further comprises a gasket and a second elastic member, the second elastic member and the first elastic member have different elastic coefficients; the first elastic member, the gasket and the second elastic member are successively sleeved on the first connecting shaft; and the second end of the first elastic member abutting against the first locking portion or the second locking portion is away from the second elastic member, an end of the second elastic member away from the first elastic member abuts against the first limiting portion.

10. The decorating tool of claim 9 , wherein the first locking portion or the second locking portion is provided with an accommodation groove, the first elastic member, the gasket, the second elastic member and the first limiting portion are accommodated in the accommodation groove.

11. The decorating tool of claim 7 , wherein the first adjusting member further comprises a second protrusion, the second protrusion and the first protrusion are located at a same side of the first adjusting member; and the second protrusion is configured for limiting rotation of the first locking portion relative to the second locking portion when the first locking portion is tightly meshed with the second locking portion.

12. The decorating tool of claim 7 , wherein the first adjusting member further comprises a warping portion, which is located at an end of the first adjusting member away from the first protrusion, and the warping portion bends along a direction opposite to the first protrusion.

13. The decorating tool of claim 4 , wherein the first locking portion is provided with a first through hole, and a third set of teeth is disposed on an inner wall of the first through hole; and the second locking portion is provided with a second through hole, and a fourth set of teeth is disposed on an inner wall of the second through hole;
the first adjusting unit comprises a locking member penetrating through the first through hole and the second through hole, and a fifth set of teeth is disposed on an outer surface of the locking member, the locking member is capable of moving in the first through hole and the second through hole along an axial line of the first through hole and the second through hole, so that the fifth set of teeth mesh with both the third set o
