[0028] Working principle:

[0029] In use, first, the nylon sleeve 2 is slid onto the core rod 1, then the spacer body 3 is installed on the nylon sleeve 2, after the spacer body 3 is installed on the nylon sleeve 2, the cover plate 5 can be slid onto the core rod 1, and the cover plate 5 is attached to the nylon sleeve 2 and the spacer body 3, after the cover plate 5 is installed, the quick connecting mechanism 6 can be installed in the core rod 1, and the position of the cover plate 5 is limited by the blocking ring 9 on the quick connecting mechanism 6, so as to lock the position of the spacer body 3, and in the sliding process of the quick connecting mechanism 6, the internal locking mechanism 7 is used to lock the position of the quick connecting mechanism 6.

[0030] The anti-skid groove 4 is formed on the nylon sleeve 2, the anti-skid groove 4 is used to increase the friction between the spacer body 3 and the nylon sleeve 2, so as to prevent the spacer body 3 from moving during processing, when the quick connecting mechanism 6 is installed in the core rod 1, the push plate 62 is only pulled away from the sliding cylinder 63, so that the top cone 68 is driven to move by the sliding column 64, and then the restriction of the top cone 68 on the protruding block 613 is released, under the pulling of the pull spring 611 on the fixed plate 612, the sliding ball 61 slides into the sliding cylinder 63, then the sliding cylinder 63 can be slid into the core rod 1, after the sliding ball 61 slides into the circular groove 8, the push plate 62 is pushed in the opposite direction, the top cone 68 is pushed to move by the push plate 62, and in the moving process of the top cone 68, the protruding block 613 is synchronously extruded, so that the sliding ball 61 is pushed out of the sliding cylinder 63 and slides into the circular groove 8, and the limiting cylinder 67 on the positioning ring 65 slides in the limiting column 610, so as to limit the position of the top cone 68.

[0031] When the positioning ring 65 slides synchronously with the slide post 64, the support rod 71 on the slide cylinder 63 slides in the positioning ring 65 through the positioning slot 66. After the end of the support rod 71 away from the slide cylinder 63 slides into the positioning slot 66, the support rod 71 slides to the center of the positioning ring 65 under the elasticity of the support rod 71 and abuts against the positioning ring 65, thereby limiting the position of the positioning ring 65, further limiting the position of the top cone 68, and further making the slide ball 61 continuously remain in the circular groove 8. When the locking of the positioning ring 65 needs to be released, the push plate 62 is pushed towards the positioning ring 65, thereby the push rod 73 abuts against the support rod 71. Under the continuous pushing of the push rod 73, the support rod 71 is moved away from the positioning ring 65, thereby the support rod 71 is pushed out of the positioning slot 66, and the locking of the positioning ring 65 is released. The limiting rod 74 on the ring plate 72 is used to limit the sliding position of the push ring 75.
