The inner wall of the locking cover 302 has a positioning groove 306, and the interior of the locking cover 302 has a movable groove 307. A locking block 308 is fitted inside the movable groove 307. One end of the locking block 308 is fixedly connected to a connecting rod 309. A spring 310 is sleeved on the surface of the connecting rod 309, and a pull ring 311 is fixedly connected to one end of the connecting rod 309. The locking base 301, locking cover 302, positioning post 303, locking groove 304, locking block 305, positioning groove 306, movable groove 307, locking block 308, connecting rod 309, spring 310, and pull ring 311... In this setup, during use, first, pipe 2 is inserted through the interior of locking base 301 and locking cover 302. Then, pull ring 311 is pulled. At this time, pull ring 311 drives locking block 308 to move into movable groove 307 via connecting rod 309. Simultaneously, locking block 308 moves and compresses spring 310, causing spring 310 to deform. When locking block 308 is fully engaged in movable groove 307, locking cover 302 is moved towards locking base 301, simultaneously causing positioning pin 303 to engage in positioning groove 306. When positioning pin 303 is fully engaged in positioning groove 306... When the pipe 2 is inside the locking cover 302, the locking cover 302 presses the locking block 305 to tightly wrap the locking block 305 around the pipe 2. At the same time, the slot 304 and the movable slot 307 are aligned. When the force applied to the pull ring 311 is released, the spring 310 rebounds and causes the locking block 308 to return to its original position. At this time, one end of the locking block 308 is engaged in the interior of the movable slot 307 and the other end is engaged in the interior of the slot 304. Thus, the locking block 308 fixes the locking cover 302 to the surface of the locking base 301, and at the same time, the locking cover 302 causes the locking block 305 to tightly clamp the pipe 2.
[0022] Furthermore, the positioning post 303 matches the size of the positioning groove 306, and the slot 304 matches the size of one end of the slot block 308. With the positioning post 303 in place, when the positioning post 303 is fully fitted inside the positioning groove 306, the slot 304 and the movable groove 307 can be aligned.
[0023] Furthermore, the cross-section of the movable groove 307 is a "T" shaped groove, and one end of the locking block 308 is fitted into the inside of the locking groove 304. Through the setting of the movable groove 307, the movable groove 307 can provide movement space for the locking block 308 and the spring 310 during use.
[0024] Furthermore, the spring 310 is disposed inside the movable groove 307. One end of the spring 310 is fixedly connected to the locking cover 302, and the other end of the spring 310 is fixedly connected to the locking block 308. With the setting of the spring 310, when in use, the spring 310 can rebound and deform to drive the locking block 308 back to its original position, so that one end of the locking block 308 is fitted into the groove 304.
[0025] Furthermore, the fixing mechanism 4 includes a connecting ring 401, a rotating member 402, an elastic band 403, a connecting band 404, a first adhesive sheet 405, a second adhesive sheet 406, and a connecting buckle 407. The two ends of the fixing base 1 are connected to the connecting ring 401. A rotating member 402 is connected to one side of the surface of the connecting ring 401. An elastic band 403 and a connecting band 404 are sewn to one end of the rotating member 402. A first adhesive sheet 405 and a second adhesive sheet 406 are sewn to one side of the surface of the elastic band 403. A connecting buckle 407 is sewn to one end of the connecting band 404. The fixing mechanism 4 is connected via the connecting ring 401, the rotating member 402, the elastic band 403, and the connecting band 404. The arrangement of the elastic band 403, the first adhesive strip 405, the second adhesive strip 406, and the connecting buckle 407 allows the elastic band 403 and the connecting band 404 to be connected to both ends of the fixed base 1 via the connecting ring 401 during use. Then, the elastic band 403 and the connecting band 404 are attached to the patient's body surface via the rotating component 402. One end of the elastic band 403 is then wrapped around the patient's body and passed through the connecting buckle 407. Finally, one end of the elastic band 403 is folded back to make the second adhesive strip 406 adhere to the first adhesive strip 405. Since the first adhesive strip 405 is the hook and loop side of the Velcro and the second adhesive strip 406 is the fleece side of the Velcro, the first adhesive strip 405 and the second adhesive strip 406 are connected to fix the fixed base 1 to the patient's body surface.
[0026] Furthermore, the elastic band 403 is made of a thin and breathable material. One end of the elastic band 403 passes through the interior of the connecting buckle 407. With the elastic band 403 in place, comfort can be increased during use because the elastic band 403 is made of a thin and breathable material.

[0028] Working principle: First, pipe 2 is passed through the locking base 301 and locking cover 302. Then, pull ring 311 is pulled. At this time, pull ring 311 drives block 308 to move into movable groove 307 through connecting rod 309. At the same time, block 308 moves and compresses spring 310, causing spring 310 to deform. When block 308 is fully engaged in movable groove 307, locking cover 302 is moved towards locking base 301, causing positioning pin 303 to engage in positioning groove 306. When positioning pin 303 is fully engaged in positioning groove 306, locking cover 302 compresses locking block 305, causing locking block 305 to tightly wrap around pipe 2. At the same time, slot 304 and movable groove 307 are aligned. Release the force applied to pull ring 311. At this time, spring 310 rebounds and causes block 308 to return to its original position. One end of block 308 is fitted inside the movable groove 307 and the other end is fitted inside the slot 304, so that block 308 fixes the locking cover 302 to the surface of locking base 301. At the same time, locking cover 302 makes locking block 305 tightly clamp pipe 2. Elastic band 403 and connecting band 404 are connected to both ends of fixed base 1 through connecting ring 401. Then, the elastic band 403 and connecting band 404 are attached to the patient's body surface by rotating part 402. Then, one end of elastic band 403 is wrapped around the patient's body and passed through connecting buckle 407. Then, one end of elastic band 403 is folded back to make the second adhesive piece 406 attach to the first adhesive piece 405. Since the first adhesive piece 405 is the hook side of hook and loop fastener and the second adhesive piece 406 is the fleece side of hook and loop fastener, the first adhesive piece 405 and the second adhesive piece 406 are connected to fix the fixed base 1 to the patient's body surface.
