As a further improvement of the scheme, the size of the moving block is matched with that of the moving groove, and the moving block is in sliding connection with the moving groove, so that the pin rod can move in a guiding mode.

As a further improvement of the scheme, the end of the broach body is provided with the limiting clamping groove, and the limiting of the broach can be realized through the clamping fit of the limiting clamping groove and the limiting clamping block.

As a further improvement of the scheme, the screw threads of the three groups of screws are the same in direction, so that the three groups of pins can be conveniently driven to move inwards or outwards simultaneously.

Compared with the prior art, the utility model has the beneficial effects that:

1. according to the utility model, the screw rod on one side is rotated, and the bevel gears I and II are meshed, so that the bevel gears II of the other two groups are driven to rotate simultaneously, the three groups of screws are driven to move inwards simultaneously by rotating, and the three groups of pin rods are driven to move simultaneously, so that the broaching tool is conveniently limited and fixed simultaneously from three directions by the cooperation of the pin rods and the pin holes, the fixing effect is good, the operation is simple, the practicability is strong, and the installation speed of the broaching tool is effectively improved.

2. According to the utility model, the limiting clamping blocks are matched with the limiting clamping grooves in a clamping way, so that the broach can be conveniently and rapidly positioned during installation, and the installation efficiency of the broach is further improved.
