[0007] A clamping mechanism, the clamping mechanism including a lead screw set on the tooling base plate, the lead screw being connected to a nut and a pressure plate, and a support block being provided on the lower end face of the pressure plate;
[0008] The positioning mechanism includes a placement hole on the V-shaped block, in which a positioning block is disposed, and the side of the plow head contacts and connects to the positioning block.
[0009] Furthermore, the plowshare has holes on its side, which are mounting holes for the shaft. The holes protrude outwards and are placed on the V-block.
[0010] Furthermore, the positioning block is connected to the V-shaped block by bolts. The positioning block has a plate-like structure and is used to limit the axial displacement of the hole position.

A connecting plate is provided on the inner side of each V-block, and the two V-blocks are connected by the connecting plate. The V-blocks are arranged in parallel, and the plow head is placed between the two V-blocks.
[0012] Furthermore, the upper surface of the V-shaped block is V-shaped, the placement hole is located at the lower part of the V-shaped groove, the placement hole is a rectangular hole, and the upper surface of the placement hole is higher than the bottom of the V-shaped groove.
[0013] Furthermore, one end of the lead screw extends into the open position hole of the plowshare, and the lower end face of the other end is the top of the support block.
[0014] The beneficial effects of the above-mentioned technical solution of this utility model are as follows:
[0015] 1. It can achieve the positioning and clamping of the plowshare. By setting the lead screw, support block and nut, the corresponding position on the plowshare can be found for clamping and fixing.
