[0010] A threaded groove is located at one end of the tool holder, and the screw is threadedly connected to the threaded groove.

[0011] The fixing mechanism, located on the rectangular rod, is used to connect and fix the rectangular rod and the cutter head.

[0012] Preferably, the fixing mechanism includes a locking block, which is fixedly connected to one end of the cutter head, and a locking groove is provided at one end of the rectangular rod, and the locking block is engaged with the locking groove.

[0013] Preferably, two rectangular sliding holes are provided on one inner wall of the slot, and a rectangular locking rod is slidably installed in each of the two rectangular sliding holes.

[0014] Preferably, the card block has two locking slots on one side, and one end of each of the two rectangular card rods is engaged with the two locking slots respectively.

[0015] Preferably, the other ends of the two rectangular clamps are fixedly installed with the same connecting plate, and a limiting block is fixedly installed at the bottom of the connecting plate.

[0016] Preferably, a notch is provided on one side of the fixing seat, and the outer side of the limiting block contacts the inner wall of the notch.

[0017] Preferably, a threaded hole is provided on one side of the fixed seat, and a rotating hole is provided on the top of the fixed seat. The screw is rotatably installed in the rotating hole, and the rotating hole communicates with the threaded hole. A bearing is fixedly installed on the top of the fixed seat, and the outer side of the screw is fixedly connected to the inner ring of the bearing.

[0018] Preferably, a locking bolt is installed in the internal thread of the threaded hole, one end of the locking bolt contacts the outer side of the screw, and the locking bolt is used to restrict the limiting block.

[0019] Compared with the prior art, the advantages of this utility model are:

[0020] This solution involves attaching the locking block to the locking slot, then pushing the connecting plate to move it. The connecting plate causes two rectangular locking rods to engage in two locking slots, fixing the locking block in place. The connecting plate then causes a limiting block to engage in a recess. Rotating the rotating block causes the screw to rotate. The screw is threadedly connected to the threaded groove. As the screw rotates, it moves vertically, which in turn causes the fixed seat to move vertically via the bearing. The fixed seat then causes the rectangular rod to move vertically, adjusting the distance between the tool holder and the tool head, thereby adjusting the overall length to meet different usage requirements. Finally, tightening the locking bolt secures the screw, and the nut of the locking bolt presses down on the limiting block to prevent it from moving, thus fixing the position of the connecting plate.

[0021] This invention facilitates the installation and fixation of the blade head, and allows for adjustment of the distance between the handle and the blade head, thereby adjusting the overall length to meet different usage needs. Attached Figure Description
