Preferably, in this embodiment, the number of the positioning plates 2, the connecting rods 21 and the adjusting devices 5 is four, four positioning plates 2 are respectively distributed on the front side of the periphery of the frame 1, and four groups of the connecting rods 21 and the adjusting devices 5 are uniformly distributed on the side of the periphery of the frame 1 at equal intervals.

Preferably, in the present embodiment, the bevel gear transmission member 9 includes a first bevel gear 91 and a second bevel gear 92, the first bevel gear 91 is fixedly connected to the second rotating shaft 8, the first bevel gear 91 is engaged with the second bevel gear 92, and the back of the second bevel gear 92 is fixedly connected to the third transmission gear 10.

Preferably, in this embodiment, the total length of the rack on the rack bar 11 is equal to one half of the circumference of the third transmission gear 10.

Preferably, in the present embodiment, a slider 121 is fixedly connected to a side of an outer wall of the nut 12 away from the rack bar 11, and the slider 121 is slidably connected to an inner wall of the adjusting device 5.

Preferably, in this embodiment, the two ends of the rack bar 11 are respectively provided with a first baffle 111 and a second baffle 112, the first baffle 111 and the second baffle 112 are both fixedly connected with the inner wall of the adjusting device 5, the first baffle 111 and the second baffle 112 can limit the moving distance of the rack bar 11 and the nut 12 to a certain extent, and the rack bar 11 is prevented from being separated from the third transmission gear 10 and the nut 12 due to the overlong moving distance of the rack bar 11 and the nut 12 and being separated from the threaded rod 13, so that the knob 15 cannot control the positioning plate 2, and the stability of the assembly is improved.

During operation (or during use), the knob 15 is rotated to enable the threaded rod 13 to drive the nut 12 and the rack rod 11 to move towards the first baffle 111 until the rack rod 11 is attached to the first baffle 111, the rack rod 11 drives the third transmission gear 10 to rotate, the second bevel gear 92 fixedly connected with the third transmission gear 10 rotates in the same direction as the third transmission gear 10, the second bevel gear 92 drives the first bevel gear 91 to rotate, the second rotating shaft 8 drives the second transmission gear 7 to rotate under the action of the first bevel gear 91, the first transmission gear 6 meshed with the second transmission gear 7 drives the first rotating shaft 4 to rotate while rotating, and the first rotating shaft 4 enables the positioning plate 2 to rotate through the connecting rod 21.
