Preferably, the material supporting frame comprises a sliding frame and a connecting frame, the sliding frame is connected to the guide space in a sliding mode, the connecting frame is connected to the sliding frame in a pressing mode through screws, and the connecting frame is fixedly connected with a piston rod of the driving cylinder.

Through above-mentioned technical scheme, when needs use this removal bracket, the piston rod of control drive actuating cylinder is flexible can. In the process of stretching the piston rod of the driving cylinder, the piston rod of the driving cylinder can drive the sliding frame to move through the connecting frame.

Preferably, the support is bent to form a cavity, the driving cylinder is arranged in the groove, and a piston rod of the driving cylinder penetrates through the support and then is connected to the material supporting frame.

Through above-mentioned technical scheme, will drive actuating cylinder and set up inside the cavity, and the recess is located the below of direction subassembly, like this at the in-process that uses this removal bracket, the support of buckling can play the guard action to driving actuating cylinder for driving actuating cylinder is difficult because of the damage of touching of external article.

Preferably, the first guide block and the second guide block are both connected to the bracket through screws in a compression manner.

Through the technical scheme, when the abrasion on the guide block I or the guide block II is serious, the guide block I or the guide block II can be taken down from the bracket and replaced.
