The second motor 162 is fixed on the second bracket 1142, and the screw rod 1621 extends in the first direction, so that when the second motor 162 is started, it can move linearly close to or away from the base 13, thereby driving the mounting bracket 114 to move linearly close to or away from the base 13 as a whole (move linearly in the first direction X).

Referring to fig. 8 and 9, the pull rod 15 is preferably cylindrical, a guide groove 152 is formed in an outer peripheral wall of the pull rod 15, the guide groove 152 extends along an axial direction of the pull rod 15 and a circumferential direction of the outer peripheral wall, two ends of the guide groove 152 are arranged in a staggered manner in the circumferential direction of the outer peripheral wall of the pull rod 15 and in the axial direction of the pull rod 15, that is, one end of the guide groove 152 is close to the first end 1111 of the housing 111, the other end of the guide groove 152 is close to the base 112, and a projection of the two ends of the guide groove 152 on a radial section of the pull rod 15 forms an included angle with. The first bracket 1141 is provided with a through hole 1143 for the pull rod 15 to pass through, and the inner wall of the through hole 1143 is provided with a protrusion 1144 matched with the guide groove 152.

In the present embodiment, for the purpose of stabilizing the transmission, the guide groove 152 has three circumferentially spaced apart, and the projection 1144 has corresponding three circumferentially spaced apart.

Therefore, when the second motor 162 is started, the screw rod 1621 rotates to push the second motor 162 to move linearly relative to the base 113, so that the mounting bracket 114 moves linearly relative to the base 113, and therefore, the pull rod 15 can rotate along with the mounting bracket 114 during the linear movement process through the cooperation of the guide groove 152 and the protrusion 1144, so as to drive the connecting rod 151 to rotate, and thus, the relative arrangement direction of the two hanging wheels 13 is switched between the third direction Z and the second direction Y.
