The second guide post 322 is located at the center of the plurality of second recesses 120 distributed in a circumferential array. When the knob 41 rotates, the third convex column 412 also rotates accordingly. Furthermore, the first recess 4120 rotates with the knob 41 to face any one of the second recesses 120. A positioning bead 5 for cooperating with any one of the second recesses 120 for positioning rotation is arranged in the first recess 4120 to realize the positioning when the knob 41 rotates.

[0035] In this embodiment, the two positioning members 3 both include a positioning plate 31 and a connecting column 32. Two second through holes 101 are formed on the first housing 11, and the two connecting columns 32 correspondingly penetrate into the cavity through the two second through holes 101. Among them, the two positioning plates 31 are correspondingly connected to one ends of the two connecting columns 32 located outside the support base 1. Second anti-slip gaskets 9 are arranged on surfaces of the two positioning plates 31 facing away from the two connecting columns 32 correspondingly, and the function of the second anti-slip gasket 9 is the same as that of the first anti-slip gasket 6. The shapes of the two positioning plates 31 are both circular, and the shapes of the two second anti-slip gaskets 9 are also both circular. One end of each of the two connecting columns 32 located in the cavity is connected with a screw rod 7, and the two connecting columns 32 and the two driven gears 43 are respectively in transmission connection through the corresponding screw rods 7. For example, one end of each of the two screw rods 7 is correspondingly threadedly connected to the two connecting columns 32, and the other end of each of the two screw rods 7 is correspondingly fixedly connected to the two driven gears 43.

[0036] Specifically, the connecting column 32 includes a first guide column 321 and second guide columns 322 disposed on both sides of the first guide column 321, and the outer walls of the two second guide columns 322 are integrally connected to the outer walls of the first guide column 321. The first guide column 321 is cylindrical in shape, and two limit baffles 3211 are correspondingly disposed at the edge between the two second guide columns 322 on the first guide column 321, and the two limit baffles 3211 extend outwardly along the radial direction of the first guide column 321. An L-shaped notch is formed at the positions where the two second guide columns 322 are adjacent to the two limit baffles 3211. The two limit baffles 3211 are both in an arc shape protruding outward on the side away from the first guide column 321, and the two second guide columns 322 are both in an arc shape protruding outward on the side away from the first guide column 321. The shape of the second through hole 101 is the same as the cross-sectional shape of the connecting post 32 formed by the first guide post 321 and the two second guide posts 322, and the size of the second through hole 101 is also adapted to the size of the connecting post 32 formed by the first guide post 321 and the two second guide posts 322 for insertion. In addition, a screw hole 3210 is provided on one end surface of the first guide post 321 facing the second housing 12, and the screw rod 7 is connected to the first guide post 321 through the screw hole 3210.

[0037] Furthermore, two limiting grooves 8 are provided on a surface of the first shell 11 facing the second shell 12. The two limiting grooves 8 are correspondingly provided at the two second through holes 101, and one end of the two connecting posts 32 correspondingly passing through the two second through holes 101 is movably clamped in the two limiting grooves 8. In order to enable the first guide post 321 to be driven to extend in and out relative to the bracket seat 1, the limiting grooves 8 are mainly used to realize the movement limiting guide of the first guide post 321 and the two second guide posts 322 (i.e., the connecting posts 32) thereon, so that when the driven gear 43 drives the first guide post 321 to move through the screw 7, the first guide post 321 can be stably moved in a predetermined direction due to the limiting grooves 8, thereby driving the positioning plate 31 to move.

[0038] Specifically, the limiting groove body 8 is composed of two semi-enclosed panels, and the semi-enclosed panels are formed by two straight plates 81 and a bent plate 82. The two straight plates 81 are correspondingly connected to the two sides of the bent plate 82 and the two straight plates 81 are parallel to each other. The concave surface of the bent plate 82 is opposite to the limiting baffle 3211, and the ends of the two straight plates 81 away from the bent plate 82 are correspondingly stuck in the recesses on both sides of the corresponding limiting baffle 3211. A limiting baffle 3211 is enclosed by a half-enclosed panel, and the concave surfaces of the bent plates 82 in the two panels are opposite to each other, so as to limit the overall movement of the connecting column 32. When the first guide column 321 and the two second guide columns 322 thereon are smoothly inserted into the cavity, and the first guide column 321 establishes a transmission connection with the driven gear 43 through the stud 7, the two panels can play a role in guiding the movement of the connecting column 32.
