[0018] The outer wall of the sliding ball 61 is slidably connected to the inner wall of the core rod 1 through the circular groove 8. The sliding ball 61 slides into the circular groove 8 to lock the position of the sliding cylinder 63, and the circular groove 8 is opened in the wall of the core rod 1. The outer wall of the sliding column 64 is slidably connected to the inner wall of the ring plate 72. The inner wall of the positioning ring 65 is slidably connected to the outer wall of the support rod 71 through the positioning groove 66, and the positioning groove 66 is opened in the wall of the positioning ring 65.

[0020] Working principle: When in use, first slide the nylon sleeve 2 onto the core rod 1, then install the spacer body 3 onto the nylon sleeve 2. After the spacer body 3 is installed onto the nylon sleeve 2, slide the cover plate 5 onto the core rod 1, and make the cover plate 5 fit the nylon sleeve 2 and the spacer body 3. After the cover plate 5 is installed, the quick connection mechanism 6 can be installed into the core rod 1, and use the retaining ring 9 on the quick connection mechanism 6 to limit the position of the cover plate 5, thereby locking the position of the spacer body 3, and during the sliding process of the quick connection mechanism 6, the internal locking mechanism 7 is used to lock the position of the quick connection mechanism 6.

[0021] An anti-slip groove 4 is provided on the nylon sleeve 2. The anti-slip groove 4 is used to increase the friction between the spacer ring body 3 and the nylon sleeve 2, thereby preventing the spacer ring body 3 from being displaced during the processing. When the quick-connect mechanism 6 is installed in the core rod 1, it is only necessary to pull the push plate 62 in the direction away from the slide cylinder 63, thereby driving the top cone 68 to move through the slide column 64, and then releasing the restriction of the top cone 68 on the protrusion 613. Under the pull of the tension spring 611 on the fixed plate 612, the sliding ball 61 slides into the slide cylinder 63, and then the slide 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 can be pushed in the reverse direction, and the top cone 68 is pushed to move by the push plate 62. During the movement of the top cone 68, the protrusion 613 is synchronously squeezed, so that the sliding ball 61 is pushed out of the slide 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, thereby limiting the position of the top cone 68.

[0022] When the positioning ring 65 slides synchronously with the sliding column 64, the support rod 71 on the slide cylinder 63 slides in the positioning ring 65 through the positioning groove 66. After the end of the support rod 71 away from the slide cylinder 63 slides into the positioning groove 66, the support rod 71 slides toward the center of the positioning ring 65 under the elastic action of the support rod 71 and presses on the positioning ring 65, thereby limiting the position of the positioning ring 65 and then limiting the position of the top cone 68, so that the sliding ball 61 continues to remain in the circular groove 8. When it is necessary to release the lock of the positioning ring 65, it is only necessary to push the push plate 62 in the direction of the positioning ring 65, so that the push rod 73 presses on the support rod 71. Under the continuous push of the push rod 73, the support rod 71 is moved in the direction away from the positioning ring 65, so that the support rod 71 is pushed out of the positioning groove 66, and the lock 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.
