[0030] During operation, the motor 302 drives the rotating shaft 309 to rotate, so that the webbing 4 is wound around the rotating shaft 309, avoiding the time-consuming and labor-intensive problem of turning the handle, and the self-locking function of the motor itself can replace the setting of mechanisms such as ratchet and latch, thereby reducing the complexity of the equipment.

[0031] In some embodiments, in order to achieve the change of the rotation speed so that the output rotation speed can better meet the requirements, in this embodiment, Figure 2 and Figure 3 As shown, a reducer 304 is disposed on the frame 1 , and the reducer output shaft 306 is connected to the rotating shaft 309 ; the motor 302 is disposed on the reducer 304 , and the input end of the reducer 304 is connected to the motor output shaft 303 .

[0032] Optionally, the reducer output shaft 306 is connected to the rotating shaft 309 by a connecting key; specifically, the reducer 304 is provided with a reducer connecting frame 305 by welding or bolting, and a plurality of bolt holes are provided on the reducer connecting frame 305. Correspondingly, a plurality of bolt holes are provided on the frame 1. The reducer connecting frame 305 is detachably fixed to the frame 1 by bolting.

The motor 302 is reinforced on the reducer 304 through the motor base 301 , and the motor base 301 can be connected to the motor 302 and the motor base 301 respectively by welding or bolting.

[0033] In some embodiments, a first hook 2 is provided at one end of the frame 1 by means of bolts or welding, etc., and the first hook 2 can be a conventional hook for mounting on a main line or a cross arm, etc.; correspondingly, a second hook 5 is provided on the webbing 4, and the second hook 5 can be a conventional hook for mounting a bypass cable, etc.
