Wherein, can exist because the frictional force between first cable and the first reel 8 leads to the indiscriminate condition of first cable winding too greatly, and first pulley 923 can be along with first cable change direction in this application, make even the frictional force between first cable and the first reel 8 too big, first guiding mechanism 9 also can play certain guide effect along first reel axial direction, along first thread groove 81 winding when making first cable winding, first pulley 923 can change along with the position change of first cable winding on first reel 8, so as to assist first cable can be along following first thread groove 81 winding always, effectively offset the frictional force between first cable and the first reel 8, make first cable more easily can be along following 8 rings of first reel and winding side by side, in order to avoid the more indiscriminate condition of first cable winding on the first reel 8. Compare in prior art, first pulley 923 can also avoid the steel wire wearing and tearing, is pulling out first cable or withdraws the in-process of first cable moreover, and the tangent mode of first cable and first gyro wheel, the phenomenon of wearing and tearing do not exist to first cable, can reach the effect of pulling out first cable or withdrawing first cable in the same direction as sliding again.

In an alternative embodiment, the present application further comprises a second cable, a second mounting shaft, and a second guide mechanism 10 for guiding the second cable; the second mounting shaft is fixedly arranged in a turbine of the worm gear reducer 6; a second winding drum 4 is sleeved on the outer side of the second mounting shaft; the second guide mechanism 10 is hinged on the connecting rod 7; the second cable is wound around the second drum 4 and the free end of the second cable is passed through the second guide means 10. This application sets up second guiding mechanism 10, the second cable stretches out back from second reel 4 and passes through second guiding mechanism 10, because second guiding mechanism 10 articulates on connecting rod 7, then second guiding mechanism 10 can be along with second cable variation direction, even make second cable and the second and frictional force between the reel too big, the second and guiding mechanism also can play certain guide effect along second reel axial direction, in order to avoid the second cable winding in second reel 4 in the condition in disorder.

Specifically, the first guide mechanism 9 and the second guide mechanism 10 are identical in structure, and the first winding drum 8 and the second winding drum 4 are identical in structure, so that the present application has two winding structures.
