[0026] The vertical side of the end of the lifting body 3 is provided with a limit pin hole A in number; the vertical side of the end of the longitudinal support beam 2 is provided with a plurality of limit pin holes B. When the limit pin hole A coincides with the limit pin hole B, the limit pin hole A11 is inserted into the limit pin hole A and the limit pin hole B for limiting; the lifting body 3 is limited and fixed after being lifted and lowered to the corresponding position on the longitudinal support beam 2.

[0027] The longitudinal support beam 2 is detachably mounted with a walking pedal 6 via a positioning pin, the bottom of the walking pedal 6 is placed on the force-bearing surface 1, and the top of the walking pedal 6 is against the bottom of the lifting body 3 for support. The top of the walking pedal 6 at the bottom of the lifting body 3 is detachably mounted on the longitudinal support beam 2 via a positioning pin; the operator can walk from the force-bearing surface 1 to the lifting body 3 via the walking pedal 6.
