[0002] The limiting device can fix the strung bodhi seeds to ensure that the bodhi seeds will not rotate when they are brushed.

[0003] For example, a limiting device for the side of a Bodhi brush with the authorization announcement number "CN218341932U" is used. The threaded structure formed by the first threaded rod and the limiting sleeve is used to press against the serial rod, and the limiting sleeve is locked, so that multiple Bodhi seeds can be limited at the same time more conveniently to avoid relative rotation between the Bodhi seeds, so that the sides of multiple Bodhi seeds can be brushed at a time, and then the serial rod can be extended into the through holes of the two brackets, and the threaded structure formed by the second threaded rod and the bracket is used to make the second threaded rod press against the serial rod, so as to avoid the serial rod from sliding horizontally when brushing and affecting the brushing effect. However, in the use of the limiting device, the Bodhi seeds and the main rod are both positioned in the form of screw tightening, and the Bodhi seeds are fixed with a protective pad to ensure stability, while the main rod is only tightened with a screw, and the contact area between the bottom of the screw and the main rod is small. When brushing, shaking will occur, which will cause damage to the friction of the main rod, which will affect the fixation of the main rod for a long time, and the stability of the limiting device cannot be guaranteed, shortening the service life of the limiting device.

[0010] Preferably, the outer wall of the straight rod is tightly pressed against the inner wall of the clamping plate.

[0011] Preferably, the outer wall of the straight rod is plugged into the inner wall of the collar.

[0012] The utility model proposes a limiting device, which has the following beneficial effects: the outer wall of the straight rod in the fixed structure passes through the interior of the rear column, and then the bent rod moves inward, and the moving bent rod moves the splint inward, so that the inner side of the splint fits the outer wall of the straight rod, and then the circular ring is threadedly connected with the outer wall of the splint from the outside to the inside, so that the circular ring fixes the splint to the outer wall of the straight rod.
