Abstract

A hand tool including a handle with a containing chamber, and a can opener that can be rotatably received in the containing chamber or unfolded connected pivotally to an end of the handle, and the can opener is made of metal material and used to open a paint can lid.

First claim

The invention claimed is:

1. A hand tool, comprising:
a handle with a containing chamber, and a can opener that is rotatably received in the containing chamber or unfolded connected pivotally to one end of the handle, wherein the can opener is made of metal material and used to open paint can lid;
a blade carrier which mounted a replaceable blade, which is rotatably received in the containing chamber or unfolded, is also pivotally connected to one end of the handle;
a putty knife that is rotatably received in the containing chamber or unfolded is also pivotally connected to one end of the handle; and
an elastic part with lateral elastic force, the elastic part is disposed in the containing chamber of the handle, and at least one of the blade carrier, the can opener and the putty knife has a positioning part at the pivotally connected end thereof, the side of the elastic part engages against the side of the pivotally connected end by the lateral elastic force when bided, while the elastic part deflects and forms a lock-fit with the positioning part when unfolded;

wherein:
the can opener includes a front end and is defined by a plate-shaped member having first and second edges and a jaw in a middle thereof;
each edge of the jaw of the plate-shaped member includes a hook-shaped member extending towards an inside of the jaw; and
a groove is arranged on the replaceable blade, and a locking member is arranged on the blade carrier; the locking member is arranged to rotate partially by stirring a pin arranged on the locking member about a positioning pin connected to the blade carrier, so as to be locked in the groove of the blade or to be held up to release the blade.

2. The hand tool according to claim 1 wherein the positioning part is a platform formed at the end of the pivoting end, and the lock-fit is formed by engaging the straight edge of the end part of the elastic part against the platform.

3. The hand tool according to claim 2 , wherein the platform has an ascending slope at a deflecting direction of the elastic part, so as to make the deflected elastic part form a tight fit automatically with the platform.

4. The hand tool according to claim 1 wherein the elastic part is an elastic piece formed by slotting partially on a spacer fixed in the containing chamber.

5. The hand tool according to claim 4 wherein the elastic piece is formed at one or both edges of one or both ends of the spacer.

6. The hand tool according to claim 1 wherein the side of the elastic part, which contacts at least one of the blade carrier, the can opener and the putty knife, has a point-shaped protrusion, and the protrusion is as such arranged that when at least one of the blade carrier, the can opener and the putty knife is received in the containing chamber, the point-shaped protrusion slides into the corresponding groove arranged on the containing chamber.

7. The hand tool according to claim 1 , wherein a through hole or a groove is arranged on the body of the putty knife.
