[0007] A further improvement is that one end of the locking bolt passes through the locking hole and abuts against the side surface of the shoe last.

[0008] A further improvement is that the other end of the locking bolt is fixedly connected with a knob.

[0009] A further improvement is that: a connection port adapted to the fixing rod is provided in the middle of the connecting head, and the connecting head can be detachably inserted on the fixing rod through the connection port.

[0010] A further improvement is that a docking block is provided at the upper end of the outer peripheral wall of the connector, a docking threaded hole is provided on the docking block, and a corresponding docking bolt is provided on the docking threaded hole.

[0011] A further improvement is that a plurality of locking holes are evenly spaced and distributed above the side walls of the left clamping block and the right clamping block.

[0012] A further improvement is that the front clamping block, the rear clamping block and the end of the locking bolt facing the shoe last are all provided with anti-skid pads.

[0013] Compared with the existing technology, the above technical solution has the following beneficial effects:

[0014] Compared with the existing clamps that can only clamp and fix the front and rear ends of the shoe last, the addition of the side clamps can clamp and fix the left and right sides on the original basis, and the clamping and fixing is more stable;

[0015] By arranging a plurality of locking holes at equal intervals and cooperating with locking bolts, the corresponding side locking position can be selected as needed. BRIEF DESCRIPTION OF THE DRAWINGS
