[0007] Furthermore, the fixing mechanism includes a fixing column, which is slidably installed in the first sliding groove to the left and right, and a round head is provided at the end of the fixing column.

[0008] Furthermore, a group of fixing grooves are respectively arranged at the left and right ends inside the connecting groove, and the fixing grooves are installed in cooperation with the fixing columns.

[0009] Furthermore, a spring is fixedly installed on the inner side of the fixing column, and the other end of the spring is fixedly installed on the inner wall of the first sliding groove.

[0010] Furthermore, a connecting rod is fixedly installed at the front end of the fixed column, and the connecting rod is slidably installed in the second sliding groove left and right. A pressing part is provided on the connecting rod, and the pressing part is located on the outer side of the heald foot body.

[0011] The beneficial effect of the utility model is that by pressing the pressing parts on both sides at the same time, the connecting rod is synchronously moved inward, so that the fixing column is retracted into the interior of the first sliding groove, and then the heald hook body is inserted into the interior of the connecting groove as a whole, and then the pressing parts on both sides are released, so that the fixing column and the round head at the front end are inserted into the fixing groove, thereby completing the fixation of the heald hook body, and the operation is simple and convenient for disassembly.
