[0035] The working principle and beneficial effects of the above technical solution are as follows: when lifting is required, the hand-pulling mechanism 5 starts working, and there are two modes to choose from.

[0040] The working principle and beneficial effects of the above technical solution are as follows: during the operation of the hand-pulling mechanism 5, dirt and debris will be formed on it due to the absorption of environmental dust, which greatly affects the lifting efficiency.

When the control module 3 opens the one-way valve 20 and the extrusion cavity 14 is in a negative pressure state, the lubricating oil enters the extrusion cavity 14 through the pipe 19, and then is squeezed to the nozzle head 22 through the pipe 21, and is sprayed on the surface of the guide chain 505 in an atomized form, so that the sliding friction is reduced when the guide chain 505 slides, thereby improving the lifting efficiency, and at the same time, the lubricating oil can play an anti-corrosion role and improve the service life of the guide chain 505.
