[0023] Please refer with emphasis to Figure 2 and Figure 3 The symmetric limiting components 5 include springs 52 fixedly arranged in the limiting grooves 231. The other ends of the symmetric springs 52 are fixedly provided with limiting balls 51. On one side of the inner wall of the symmetric limiting grooves 231 close to the limiting balls 51, limiting holes 112 are penetrated and opened corresponding to the positions of the inner walls of the connection grooves 111. The positions of the limiting holes 112 are aligned with those of the limiting balls 51 for the limiting balls 51 to pop out under the action of the springs 52 and be clamped therein.

[0024] Please refer with emphasis to Figure 2 and Figure 3 On the upper and lower sides of the symmetric limiting holes 112, sliding grooves 113 are communicated and opened. Pressing columns 3 are slidably arranged in the symmetric limiting holes 112. On the upper and lower sides of the symmetric pressing columns 3, sliding blocks 31 are fixedly provided. The symmetric sliding blocks 31 and the sliding grooves 113 are matched with each other.

[0025] Please refer with emphasis to Figure 2 On the front and rear end surfaces of the symmetrically arranged multiple roller bodies 2, multiple mounting holes 22 are symmetrically provided. Removable fixing disks 4 are connected to the front ends and the rear ends of the multiple symmetric roller bodies 2.

[0026] Please refer with emphasis to Figure 2 A rubber pressing sleeve 21 is sleeved outside the multiple roller bodies 2. Preferably,

[0027] The outer part of the roller body 2 is a non-flat surface with friction or grooves. The rubber pressing sleeve 21 is made of a soft body. The inner surface of the rubber pressing sleeve 21 is attached to the non-flat outer surface of the roller body 2.

[0029] Example 1:

[0030] The connecting rod 23 on the inner side of the multiple roller bodies 2 is connected to the connecting rod 11 symmetrically arranged on the outer surface of the rotating shaft 1 through the connecting groove 111. At this time, the spring 52 in the limiting groove 231 extends most of the limiting ball 51 into the limiting hole 112, so that the connecting rod 11 and the connecting rod 2 23 are fixedly connected. The multiple roller bodies 2 are connected in the above manner in sequence to form a cylindrical shape with a certain length.

Therefore, the fixing plates 4 at the head and tail ends are removed, and then the rubber pressing sleeve 21 is removed. Then, the roller body 2 which is symmetrical at the head and tail ends is pressed symmetrically by pressing the pressing columns 3. The pressing columns 3 slide and squeeze the limiting balls 51 in the limiting holes 112 under the cooperation of the slider 31 and the slide groove 113, so that the limiting balls 51 leave the limiting holes 112. At this time, the limiting balls 51 and the inner wall of the connecting groove 111 are on the same horizontal plane, which makes it convenient to connect While the rod 11 is separated from the connecting rod 2 23, it is also convenient to separate the upper and lower symmetrical roller bodies 2 at the head and tail ends. Different numbers of roller bodies 2 can be removed according to the specifications of the pole pieces to adapt to the lengths of the blank areas on both sides of the pole pieces of different specifications. The fixed plate 4 is then connected through the matching holes 42, the mounting columns 41, and the mounting holes 22, and then the rubber sleeves 21 of different specifications are put on the outer surface of the roller body 2. Therefore, there is no need to produce multiple roller bodies 2 of different specifications, which can save resources to a certain extent and reduce unnecessary waste.
