[0016] By adopting the above technical solution, the lifting hole is used to connect the lifting hook to realize the installation of the rear template.

[0017] Beneficial effects: The transmission structure of this utility model is inlaid in the front template. The transmission gear drives the nut sleeve to rotate, and the nut sleeve moves in a spiral motion with the T-shaped thread. The pressure plate presses the nut sleeve to make it move as a whole with the front template. The rolling friction of the thrust bearing reduces the coefficient of motion friction, thereby realizing the adjustment of the up and down movement of the front template. It is highly efficient, small in size, occupies little space, and allows the overall height of the machine to be made smaller. Attached Figure Description
