When operating, the user can drive the two sets of threaded blocks to move through the threaded shafts in each set of mold clamping structures, thereby driving the clamping plate to move to one side, thereby reducing the distance between the two sets of clamping blocks, thereby achieving the tightening of one corner of the mold, and achieving the fixing effect of a specific mold by fixing the four corners. The user can also achieve the effect of quick disassembly by canceling the fixation of the four corners, thereby meeting the needs of on-site use.

[0006] As a preferred technical solution of the utility model, a protruding structure is provided at the bottom end of the carrier plate, and the size of the protruding structure is matched with the size of the slide groove.

[0007] As a preferred technical solution of the utility model, the bite plate and the deflection frame are combined into a clamp-type structure, and a bite block is fixed to one end of the bite plate and the deflection frame.

[0008] As a preferred technical solution of the utility model, the directions of the threads in the two groups of threaded blocks are opposite.

[0009] As a preferred technical solution of the utility model, a rotating block is fixed on the outer side of each group of threaded shafts.

[0010] As a preferred technical solution of the utility model, a control switch assembly is provided at the front end of the base plate.
