[0031] In specific use, the driving motor 10 is started, and the transmission between the rollers 6 on the anchor point roller line 1 and the opening and closing roller line 2 is realized through the chain wheel two 11, the chain wheel one 7 and the chain.

[0032] When it is necessary to open the opening and closing roller line 2, the end thereof is lifted upward, the slide rod 17 slides on the positioning plate 18, and the lifting degree of the staff can be reduced by the elastic force of the spring one 22. During the lifting process, the pawl 26 can slide on the ratchet teeth 33 without limiting the slide column 32. When the opening and closing roller line 2 moves downward, the pawl 26 is clamped on the ratchet teeth 33 under the action of the spring two 27, so as to avoid the downward movement of the opening and closing roller line 2. When it is necessary to move the opening and closing roller line 2 downward, the handle 28 is rotated, the extension plate 30 is pulled through the linkage plate and the connecting rod 25, the pawl 26 is rotated to leave the ratchet teeth 33, so as to rotate the opening and closing roller line 2 downward.
