[0024] The effect achieved by the entire embodiment 1 is as follows: Figure 1 and Figure 2 As shown, the limiter 104 can utilize the expansion force of the compression spring 103 and the force of the fixing bolt 203 being screwed in, so that the limiter 104 and the anti-slip pad 105 can more fully contact the heating pipe and the connecting pipe, thereby ensuring that the two pipes can be stably located between the limiters 104, while also avoiding displacement during subsequent bonding, thereby increasing the speed of pipe connection.

[0025] Embodiment 2, as Figure 1-Figure 4As shown, one end of the compression spring 103 is fixedly connected to the outer surface of the limiter 104, the other end of the compression spring 103 is fixedly connected to the inner surface of the semicircular ring 101, the outer surface of the movable plate 108 is slidably connected to the inner surface wall of the slide groove 107, a circular hole 109 is opened on the front outer surface of the movable plate 108 near one side, a micro spring 110 is arranged on the inner surface of the circular hole 109, a connecting disc 111 is slidably connected to the inner surface wall of the circular hole 109 near the front side, a round rod 112 is fixedly connected to the center of the front outer surface of the connecting disc 111, and the outer surface of the round rod 112 is connected to the connecting plate The inner surface of the semicircular ring 106 is slidably connected, one end of the micro spring 110 is fixedly connected to the inner surface wall of the circular hole 109, and the other end of the micro spring 110 is fixedly connected to the outer surface of the rear side of the connecting disk 111.

[0026] The effect achieved by the entire embodiment 2 is as follows: Figure 1 , Figure 3 and Figure 4 As shown, through the cooperation of the connecting plate 106, the slide groove 107 and the movable plate 108, the distance between the two semicircular rings 101 can be adjusted so that they can adapt to heating pipes and connecting pipes of different lengths in the future, and the user can adjust the distance between the two according to actual needs. Through the cooperation of the micro spring 110, the connecting disc 111 and the round rod 112, the movable plate 108 can be limited to prevent it from sliding in the slide groove 107 in the future.

[0027] Working principle: When in use, the user first presses the round rod 112, then the connecting disc 111 and the micro spring 110 are subjected to force and move backward in the circular hole 109, and after the round rod 112 is pressed to a certain position, it will be pressed into the circular hole 109, then the user can move the movable plate 108 so that it can slide back and forth in the slide groove 107, and the semicircular ring 101 on the other side is driven by the force, and after adjusting the appropriate position, the round rod 112 can be moved out of the opening on the connecting plate 106 to limit the movable plate 108. After the operation, the spacing between the two semicircular rings 101 can be adjusted, and the user can adjust it according to actual needs. After the adjustment, the user can adjust the heating pipe and The connecting pipe is placed into the semicircular ring 101 and also between multiple limit members 104. When placed in, the slide rod 102 and the compression spring 103 are forced to change their own state. After placement, the limit member 104 and the anti-skid pad 105 use the expansion force of the compression spring 103 to effectively apply force to the heating pipe and the connecting pipe. Then the user screws the fixing bolt 203 into the corresponding threaded hole 202, so the limit member 104 and the anti-skid pad 105 can use the force of screwing in to make them fully contact with the outer surface of the heating pipe and the connecting pipe to avoid subsequent displacement during bonding. After fixing, since the two pipes are already in a relative connection state, the user can use adhesive to bond them, which can increase the speed of pipe connection after the whole is completed.
