Abstract

A power device includes a power tool, a mounting plate, a mounting table, a positioning assembly, and a locking assembly. The positioning assembly includes a positioning piece. A positioning space is formed between the positioning piece and the mounting table. An end of the mounting plate is enabled to be inserted into the positioning space so that the mounting plate is pre-positioned. The locking assembly includes a movable piece and a locking piece. The movable piece includes a support position where the mounting plate is supported and an unlocked position where support for the mounting plate is released. The locking piece fixes at least the mounting plate to the mounting table.

First claim

What is claimed is:

1. A power device, comprising:
a power tool;
a mounting plate detachably connected to the power tool; and
a mounting table for installation of the mounting plate,
wherein the power device further comprises:
a positioning assembly comprising a positioning piece, wherein a positioning space is formed between the positioning piece and the mounting table and an end of the mounting plate is insertable into the positioning space to pre-position the mounting plate,
a locking assembly comprising a movable piece and a locking piece, wherein the movable piece comprises a support position in which the mounting plate is supported and an unlocked position in which support for the mounting plate is released and the locking piece fixes at least the mounting plate to the mounting table, and

wherein the locking piece comprises at least one bolt and the at least one bolt fixedly connects the mounting plate to the mounting table.

2. The power device of claim 1 , wherein the movable piece is provided with a guide groove, the mounting table is provided with a guide rod, the guide rod passes through the guide groove, and the movable piece is movable with respect to the mounting table through the guide groove.

3. The power device of claim 1 , wherein the locking piece comprises a first screw rod and a first nut screwed to the first screw rod, the first screw rod is fixedly connected to the mounting table, and the first nut is enabled to be screwed to the first screw rod so as to lock the movable piece and the mounting table.

4. The power device of claim 3 , further comprising an auxiliary locking assembly, wherein the auxiliary locking assembly comprises a pressing piece and an auxiliary locking piece, the pressing piece is capable of abutting against a side of the mounting plate facing away from the mounting table, and the auxiliary locking piece is capable of locking the pressing piece and the mounting table.

5. The power device of claim 4 , wherein the auxiliary locking piece comprises a second screw rod and a second nut screwed to the second screw rod, the second screw rod is fixedly connected to the mounting table, and the second nut is enabled to be screwed to the second screw rod so as to abut against the pressing piece.

6. The power device of claim 4 , wherein the pressing piece and the positioning piece are disposed on a same side of the mounting plate.

7. The power device of claim 1 , wherein a foolproof assembly is disposed between the mounting table and the mounting plate, the foolproof assembly comprises a protrusion and a groove, one of the protrusion or the groove is disposed on the mounting table, the other of the protrusion or the groove is disposed on the mounting plate, and the protrusion is inserted into the groove while the end of the mounting plate is inserted into the positioning space.

8. The power device of claim 1 , wherein the mounting plate is provided with a plurality of sets of positioning holes, each of the plurality of sets of positioning holes are arranged in a circle, and the plurality of sets of positioning holes are distributed on circles of different diameters.

9. The power device of claim 1 , further comprising a depth adjustment assembly configured to adjust an operation depth of the power tool, wherein the mounting plate is provided with an escape hole that allows the depth adjustment assembly to pass through.

10. A method for installing a power tool to a mounting table through a mounting plate, comprising:
assembling, by a plurality of screws, the power tool with the mounting plate;
pre-positioning, by inserting an end of the mounting plate to a positioning space formed between a positioning piece and the mounting table, the mounting plate;
supporting, by moving a movable piece from an unlocked position to a support position, the mounting plate; and
fixing, by a locking piece, at least the mounting plate to the mounting table, wherein the locking piece comprises at least one bolt, wherein the at least one bolt fixedly connects the mounting plate to the mounting table.

11. The method of claim 10 , wherein the movable piece is provided with a guide groove, the mounting table is provided with a guide rod, the guide rod passes through the guide groove, and the movable piece is movable with respect to the mounting table through the guide groove.

12. The method of claim 10 , wherein the locking piece comprises a first screw rod and a first nut screwed to the first screw rod, the first screw rod is fixedly connected to the mounting table, and the first nut is enabled to be screwed to the first screw rod so as to lock the movable piece and the mounting table.

13. The method of claim 12 , further comprising: locking, by an auxiliary locking piece, a pressing piece and the mounting table, wherein the pressing piece is capable of abutting against a side of the mounting plate facing away from the mounting table.

14. The method of claim 13 , wherein the auxiliary locking piece comprises a second screw rod and a second nut screwed to the second screw rod, the second screw rod is fixedly connected to the mounting table, and the second nut is enabled to be screwed to the second screw rod so as to abut against the pressing piece.

15. The method of claim 13 , wherein the pressing piece and the positioning piece are disposed on a same side of the mounting plate.

16. The method of claim 10 , wherein a foolproof assembly is disposed between the mounting table and the mounting plate, the foolproof assembly comprises a protrusion and a groove, one of the protrusion or the groove is disposed on the mounting table, the other of the protrusion or the groove is disposed on the mounting plate, and the protrusion is inserted into the groove while the end of the mounting plate is inserted into the positioning space.

17. The method of claim 10 , wherein the mounting plate is provided with a plurality of sets of positioning holes, each of the plurality of sets of positioning holes are arranged in a circle, and the plurality of sets of positioning holes are distributed on circles of different diameters.

18. The method of claim 10 , further comprising: adjusting, by a depth adjustment assembly, an operation depth of the power tool, wherein the mounting plate is provided with an escape hole that allows the depth adjustment assembly to pass through.
