[0020] Preferably, the free ends of the first pair of connectors of the utility model are provided with plug-in parts, and the front ends of the second pair of connectors are provided with plug-in holes corresponding to the plug-in parts. During installation, the plug-in parts are inserted into the inside of the plug-in holes to ensure that the first pair of connectors and the second pair of connectors can be normally plugged in, thereby realizing rapid installation and disassembly between the first pair of connectors and the second pair of connectors.
[0021] See also Figure 3 and Figure 4In addition, the outer wall of the plug-in part of the utility model is provided with two symmetrically arranged limiting ring protrusions, and an obstacle avoidance space 23 is provided between the two limiting ring protrusions to ensure that the first pair of joints can be normally inserted into the interior of the second pair of joints. A limiting protrusion 31 is provided inside the plug-in hole, and a clamping area corresponding to the thickness of the limiting ring protrusion is formed between the limiting protrusion 31 and the bottom of the plug-in hole. After the first pair of joints are inserted into the interior of the second pair of joints, the first pair of joints and the second pair of joints are relatively rotated at a certain angle to ensure that the first pair of joints and the second pair of joints are clamped with each other. The outer wall of the plug-in part is provided with a clamping groove 21, and the position of the clamping groove 21 corresponds to the position of the limiting ring protrusion. The inner wall of the limiting protrusion 31 is fitted with the outer wall of the plug-in part, and the inner wall of the limiting protrusion 31 is slidably provided with a clamping column 6 that cooperates with the clamping groove 21. When the limiting protrusion 31 is rotated to correspond to the clamping groove 21, the clamping column 6 is clamped to the interior of the clamping groove 21 by force, ensuring that the positions of the first pair of joints and the second pair of joints are fixed at this time.
[0022] Furthermore, the inner wall of the limiting protrusion 31 of the utility model is provided with a sliding hole 32, and the clamping post 6 is slidably connected to the inside of the sliding hole 32. A thrust spring 5 is provided between the clamping post 6 and the bottom of the sliding hole 32, and the clamping post 6 is clamped to the inside of the clamping slot 21 by the thrust of the thrust spring 5. When disassembly is required, the first pair of joints and the second pair of joints are forced to rotate by manpower, and the clamping post 6 is lifted and compressed into the inside of the sliding hole 32 by the beveled edge of the edge of the clamping slot 21. The front end of the plug-in part is provided with a chamfered abutment 24, and the bottom of the plug-in hole is provided with an abutment groove 33 corresponding to the abutment 24.

[0023] In this embodiment, combined with Figure 1 to Figure 4 When in use, when it is necessary to dock the sliding sleeve 2 with the driven shaft 3, the first pair of joints and the second pair of joints are manually plugged in. At this time, the limiting flange 22 and the limiting protrusion 31 are misaligned to ensure the normal plug-in process of the first pair of joints and the second pair of joints. Then the first pair of joints and the second pair of joints are relatively rotated at a certain angle. At this time, the limiting flange 22 and the limiting protrusion 31 coincide with each other, and the position of the clamping column 6 corresponds to the clamping groove 21. The clamping column 6 is clamped to the inside of the clamping groove 21 under the action of the thrust spring 5 to prevent the first pair of joints and the second pair of joints from rotating relative to each other during the movement. When disassembly is required, the first pair of joints and the second pair of joints are manually forced to rotate. At this time, the beveled edge of the edge of the clamping groove 21 compresses the clamping column 6 into the inside of the sliding hole 32, releases the clamping relationship between the clamping column 6 and the clamping groove 21, and completes the quick disassembly process.
