The guiding arc ring 108 is fixedly connected with the abutting column 105 and is located on the outer side wall of the abutting column 105. The limiting block 107 is fixedly connected with the abutting column 105 and is slidably arranged in the limiting groove 103. When using the connection module to connect multiple pipe bodies 101, during the connection process, one end of the pipe body 101 close to the installation cavity 102 is aligned with one end of the other pipe body 101 close to the clamping groove 104, and a force is applied. The arc surface of the guiding arc ring 108 contacts the pipe body 101, the guiding arc ring 108 is stressed, the limiting block 107 is squeezed into the installation cavity 102. At this time, the abutting spring 106 is compressed and has a resilience force. When the installation cavity 102 and the clamping groove 104 are communicated, under the action of the abutting spring 106, the abutting column 105 pops into the clamping groove 104. At this time, the two pipe bodies 101 are relatively fixed. At the same time, the limiting block 107 slides in the limiting groove 103, and the limiting block 107 cooperates with the limiting groove 103 to improve the stability of the abutting column 105 during the movement process. According to the actual use situation, multiple split pipe bodies 101 are adopted to adjust the number of the pipe bodies 101 to form a manifold with different lengths, which can be applicable to different use situations.
