[0028] The bidirectional screw rod 37 can be rotated by the knob 38 , and the rotating shaft 33 can be driven to rotate by the motor 34 .

[0029] The mounting assembly 3 further comprises a sliding sleeve 39 and a driving wheel 311. The sliding sleeve 39 is rotatably connected to an outer surface of one side of the sliding frame 36, and the sliding sleeve 39 and the driving wheel 311 are slidably connected to an outer wall of the rotating shaft 33. Two clamping blocks 391 are symmetrically arranged on an outer surface of one side of the sliding sleeve 39. The driving wheel 311 comprises an upper half wheel 3111 and a lower half wheel 3112. The outer walls of the upper half wheel 3111 and the lower half wheel 3112 are both provided with spiral ribs 3113. The outer surfaces of the front and rear sides of the upper half wheel 3111 and the lower half wheel 3112 are both provided with clamping grooves 3114 corresponding to the clamping blocks 391. A plurality of bolt holes 3115 are arranged at the connection between the upper half wheel 3111 and the lower half wheel 3112.

[0032] Through the two sliding frames 36 distributed in the length direction of the bidirectional screw rod 37, when the bidirectional screw rod 37 rotates, it will drive the two sliding frames 36 to move together to the center or separate to both sides, thereby driving the two sliding sleeves 39 to move closer to or away from the two driving wheels 311. When the four blocks 391 are respectively inserted into the four slots 3114, the driving wheel 311 is fixed in the center on the outer wall of the rotating shaft 33.

[0033] Embodiment 2: The auxiliary component 4 includes a slide groove 41, which is opened on the top surface of the base 1. The sliding seat 31 is slidably connected to the base 1 through the slide groove 41. A cylindrical rod 42 is fixedly connected to the outer surface of one side of the sliding seat 31. A fixing frame 43 is fixedly connected to the outer surface of one side of the base 1. A handle 44 is rotatably connected to the inner wall of the fixing frame 43. A butterfly bolt 45 is threadedly connected to the inner wall of the handle 44. A strip plate 46 is fixedly connected to one end of the rotating shaft of the handle 44.

[0034] The width of the limiting groove 47 is equal to the diameter of the cylindrical rod 42. When the handle 44 is vertical, the butterfly bolt 45 is used to fix the handle 44 to the fixing frame 43;

[0035] By raising the handle 44, the cylindrical rod 42 can be prevented from moving left and right through the limit groove 47, and the position of the sliding seat 31 is fixed. By loosening the butterfly bolt 45, the cylindrical rod 42 and the sliding seat 31 can move left and right along the direction of the sliding groove 41, thereby moving the sliding seat 31 away from the dividing plate body 2.

[0036] Among them, the cylindrical rod 42, the fixing frame 43, the handle 44, the butterfly bolt 45, the strip plate 46 and the limit groove 47 are each in two pieces, which are symmetrically distributed on the front and rear sides of the base 1. The outer wall of the indexing plate body 2 is provided with a plurality of rollers in an equiangular annular array, and the indexing plate body 2 is engaged with the spiral rib 3113 through the plurality of rollers.

[0037] By keeping the sliding seat 31 and the spiral rib 3113 away from the indexing plate body 2 , interference between the drive wheel 311 and the indexing plate body 2 during disassembly and installation can be avoided.

[0038] The working process of the utility model is as follows:

[0039] First, turn the knob 38 to move the two sliding frames 36 away from the front and rear sides along the slide rail 35, and drive the two sliding sleeves 39 to move away. At this time, the four clamping blocks 391 are respectively disengaged from the four clamping grooves 3114. Then, the driving wheel 311 can be removed from the outer wall of the rotating shaft 33 by removing the bolts in the multiple bolt holes 3115. After the driving wheel 311 is maintained or replaced, the driving wheel 311 is reinstalled on the outer wall of the rotating shaft 33, and the knob 38 is turned to make the four clamping blocks 391 reinsert into the four clamping grooves 3114 respectively, and the driving wheel 311 is fixed in the center of the rotating shaft 33. Before removing the driving wheel 311, first The butterfly bolt 45 is loosened and the strip plate 46 is rotated. At this time, the limit groove 47 no longer restricts the left and right movement of the cylindrical rod 42. The sliding seat 31 and the cylindrical rod 42 are slid along the slide groove 41 and away from the dividing plate body 2. After the driving wheel 311 is replaced, the cylindrical rod 42 is slid to make the spiral rib 3113 close to the dividing plate body 2. At the same time, the rotating shaft 33 is adjusted to rotate so that the spiral rib 3113 re-engages with the roller on the outer wall of the dividing plate body 2, and the rotating shaft 33 is rotated to a vertical state again. The handle 44 is fixed to the fixing frame 43 by the butterfly bolt 45. At this time, the cylindrical rod 42 and the sliding seat 31 are restricted and fixed in position by the limit groove 47.
