[0021] The invention seals and protects the connection between the deep groove ball bearing and the spiral rod by the cooperation of the bearing end cover, the gasket and the sealing ring, and is convenient for disassembly so as to lubricate the deep groove ball bearing.

[0022] The connecting rod rotating shaft of the present invention is connected to the rotating output end of the leg motor through a coupling, which is convenient to connect and simple to assemble.

[0023] The present invention can detachably mount the push rod motor on the bottom of the back plate through the cooperation of the motor mounting seat, the movable block, the second bolt and the third bolt, so as to facilitate replacement and maintenance, and at the same time provide protection for the push rod motor and extend its service life.
