[0022] The following is a detailed description of the specific settings and functions of its tightening mechanism.
[0023] Reference Figure 1 , Figure 2 , Figure 3 , Figure 4 and Figure 5As shown, in this embodiment: when the user needs to fix the sleeve body 105, the user can sleeve the sleeve body 105 on the front end of the surface of the column 1, and then the user can pull the pull plate 109 inward, thereby driving the insertion rod 108 to be inserted into the insertion hole 111 under the action of the pulling force, thereby completing the fixation of the sleeve body 105, and by setting the outer diameter of the insertion rod 108 to match the inner diameter of the insertion hole 111, the sleeve body 105 is fixed more firmly and not easy to shake, so that it is more convenient for the user to tighten the sleeve body 105, and the first sliding groove 103 is provided on both sides of the left and right sides of the static ring 101, and the first sliding groove 103 is slidably connected to the first sliding block 104, and the facing surface of the first sliding block 104 is connected to the sleeve body 105. The first slide groove 103 and the first slider 104 are provided to allow the sleeve body 105 to drive the first slider 104 to slide in the first slide groove 103 under the action of tension, thereby making it easier to install, tighten or remove the sleeve body 105. The end of the pull plate 109 close to the first connecting plate 107 is fixedly connected to the first spring 110, and the end of the first spring 110 close to the first connecting plate 107 is fixedly connected to the first connecting plate 107. When the user installs and fixes the sleeve body 105, the pull plate 109 is pulled outward to allow the first spring 110 to store force under the action of tension. When the user puts the sleeve body 105 to the final position, the user Loosen the pull plate 109, so that the first spring 110 rebounds and releases under the action of the recoil force, driving the insertion rod 108 to quickly insert into the insertion hole 111, so that the user can quickly fix the sleeve body 105, and the front end of the steel ring 106 is fixedly connected with a connecting ring 112, and a slot 113 is provided on the surface of the connecting ring 112. The front end of the steel ring 106 is fixedly connected with two second connecting plates 114, and the facing surfaces of the second connecting plates 114 are fixedly connected with a sliding box 115. The interior of the sliding box 115 is fixedly connected with a plurality of second springs 116 and evenly distributed inside the sliding box 115. The facing surfaces of the second springs 116 are fixedly connected with a push plate 117, and the surface of the push plate 117 is slidably connected to the interior of the slot 113. The facing surfaces of the push plate 117 The slide box 115 is fitted and connected with the surface of the slide box 115. Before the user installs and fixes the shaft sleeve body 105, the user can pull the push plate 117 outward, so that the second spring 116 is charged under the action of the pulling force. When the user has completed the fixing of the shaft sleeve body 105, the user can release the push plate 117, so that the second spring 116 rebounds and releases under the action of the returning force, driving the push plate 117 to pop up and clamp the shaft sleeve body 105 for a second fixation, so that the shaft sleeve body 105 is more stable and will not shake. The upper and lower ends of the slide box 115 are provided with second slide grooves 118, and the second slide grooves 118 are slidably connected with the second slider 119. The opposite surface of the second slider 119 is fixedly connected to the push plate 117.By providing the second slide slot 118 and the second slider 119, when the user pulls the push plate 117 outward and the second spring 116 drives the push plate 117 to clamp the sleeve body 105 more smoothly, there will be no jamming that causes the device to be unable to be used normally. The upper and lower ends of the push plate 117 are fixedly connected to the first limit block 120, and the second limit block 121 is fixedly connected inside the second slide slot 118. The end of the first limit block 120 close to the second limit block 121 is closely connected to the end of the second limit block 121 close to the first limit block 120. By providing the first limit block 120 and the second limit block 121, when the push plate 117 is ejected to the top under the action of the second spring 116, the first limit block 120 is closely connected to the second limit block 121, so as to avoid the second spring 116 driving the push plate 117 to eject the slide box 115 under the action of the return force, so that the device cannot be used normally.
[0024] The practical working principle of the present invention is that when the user needs to fix the shaft sleeve body 105, the user can sleeve the shaft sleeve body 105 on the front end of the surface of the column 1, and then the user can pull the pull plate 109 inward, thereby driving the insertion rod 108 to be inserted into the insertion hole 111 under the action of the pulling force, thereby completing the fixing of the shaft sleeve body 105. By setting the outer diameter of the insertion rod 108 to match the inner diameter of the insertion hole 111, the shaft sleeve body 105 is fixed more firmly and is not easy to shake, so that it is more convenient for the user to tighten the shaft sleeve body 105. When the user is installing or disassembling the shaft sleeve body 105 for maintenance By setting the first slide groove 103 and the first slider 104, the sleeve body 105 drives the first slider 104 to slide in the first slide groove 103 under the action of tension, so that it is easier to install, tighten or disassemble the sleeve body 105. When the user is installing and fixing the sleeve body 105, the pull plate 109 is pulled outward to make the first spring 110 accumulate force under the action of tension. When the user puts the sleeve body 105 to the most complete position, the user releases the pull plate 109, so that the first spring 110 rebounds and releases under the action of the rebound force, driving the insertion rod 108 to quickly insert into the socket 111 The sleeve body 105 is convenient for the user to quickly fix the sleeve body 105. Before the user installs and fixes the sleeve body 105, the user can pull the abutment plate 117 outward, so that the second spring 116 is charged under the action of the pulling force. When the user has completed the fixing of the sleeve body 105, the user can release the abutment plate 117, so that the second spring 116 rebounds and releases under the action of the return force, driving the abutment plate 117 to pop out and clamp the sleeve body 105 for a second fixation, so that the sleeve body 105 is more stable and will not shake. By setting the second slide groove 118 and the first The second slider 119 makes it smoother when the user pulls the push plate 117 and the second spring 116 outward to drive the push plate 117 to clamp the sleeve body 105, and there will be no jamming that causes the device to be unable to be used normally. By setting the first limit block 120 and the second limit block 121, when the second spring 116 pops out the push plate 117 to the top under the action of the rebound force, the first limit block 120 and the second limit block 121 are fitted together, thereby avoiding the second spring 116 from driving the push plate 117 to pop out of the slide box 115 under the action of the rebound force, causing the device to be unable to be used normally.
