Detailed Description

Referring to fig. 1-2, the present invention provides a technical solution:

the utility model provides a rope clamping device for elevator rescue, includes

mount

1, and 1 right wall connection of mount is fixed with

handle

2, and 1 right side of mount is equipped with centre gripping subassembly 3, and 1 upper end bottom surface of mount has set firmly

motor

4, and 1 rear end left wall connection of mount is fixed with

dead lever

5, and 5 inner walls of dead lever rotate and are connected with

transfer line
