Embodiment 2

[0043] This embodiment is generally the same as Embodiment 1, only some features are different, and only the differences are described in detail below:

[0044] The fixed pulley 144 is arranged on the top of the first bracket 11 away from the end of the driving device 14, and the two ends of the top of the second support frame are respectively provided with guide pulleys 18, and the driving cables 145 are respectively connected with the anti-slip driving pulley 1432 and the fixed pulley 144 in rotation and bypassed respectively. Two guide pulleys 18 on the second bracing frame, two points on the driving steel cable 145 with the same moving direction are fixedly connected with the movable end of the retaining cloth 13 respectively, and when the movable end of the retaining cloth 13 is driven by the driving steel cable 145, The movable end of the retaining cloth 13 can be kept in translation all the time to avoid tilting.

Embodiment 3

[0046] This embodiment is generally the same as Embodiment 1, only some features are different, and only the differences are described in detail below:

[0047] The anti-skid pad 148 inner wall is provided with a connecting portion 1485, the connecting portion 1485 is an annular protrusion set along the anti-skid pad 148 inner wall centered on the anti-skid driving pulley 1432 axis, and the groove bottom of the anti-skid driving pulley 1432 is provided with a groove along the anti-skid driving pulley 1432. The connecting groove 14323 around the groove, the connecting part 1485 is inserted into the connecting groove 14323 and fixed, the setting of the connecting part 1485 can make the anti-skid pad 148 and the anti-skid driving pulley 1432 cooperate more closely, and play a good role in preventing the anti-skid pad 148 and the anti-skid driving pulley 1432 produces the effect of relative sliding, and the connection part 1485 can increase the thickness of the middle part of the a...
