2. The loop is convenient to replace. The movable sleeve is connected with the base through the pin shaft and the wedge, and the movable sleeve is convenient and quick to replace when needing to be replaced.

3. The cylinder adjusting mechanism is convenient to install and debug.

4. The sleeve lifting roller is convenient to replace. The sleeve lifting roller is a quick-wear part and is convenient to disassemble according to the assembling mode.

5. The service life of the piston sleeve body is prolonged. Wear-resisting bush is installed to the internal passageway of loop, use after the longer time pull down the bolt change bush can, avoided the change of loop body.
