Each built-in block 113 is fixedly connected to the bottom block 112, and the bottom block 112 is fixedly connected to the corresponding insertion rod 111. The limiting ring 118 is connected to the guide cylinder 11. 7. Fixed connection: The guide cylinder 117 is fixedly connected to the slide cylinder 116, the slide cylinder 116 is fixedly connected to the pressure ring 110, each anti-slip block 120 is fixedly connected to the anti-slip ring 119, and the anti-slip ring 119 is fixedly connected to the support ring 105. The spring 114 and the locking block 115 in the locking assembly 107 cooperate with the pressure ring 110 and the multiple insertion rods 111 in the ring pressing assembly 106 to achieve rapid ring pressing connection. The sliding cylinder 116 and the guide cylinder 117 within the limiting assembly 108 provide installation guidance for external pipes. After being inserted into the limiting ring 118, the external pipes are held and pressed by the guide cylinder 117 and the sliding cylinder 116, preventing them from moving. This design, without affecting the normal connection to external pipes, solves the problem that the squeezed steel ball cannot guarantee its sliding trajectory, resulting in poor stability when connecting to other pipes and hindering its widespread adoption, through the locking block 115 and the elastic element.

Each locking block 115 is located at one end of the corresponding spring member 114, and the other end of each spring member 114 is located on one side of the corresponding built-in block 113. Each built-in block 113 is located inside the bottom block 112, which is located at the lower end of the corresponding insertion rod 111.

The position of each built-in block 113 is relatively fixed and not easily changed, which provides installation support for the corresponding spring member 114. When the insert rod 111 and the bottom block 112 are inserted into the bottom of the inner side of the support ring 105, the outer side of each locking block 115 is no longer restricted, and it pops out under the elastic action of the corresponding spring member 114, thereby locking the bottom block 112 and the insert rod 111. At this time, the pressure ring 110 also fits with the support ring 105, and the external pipe is connected. When connecting the external pipe, first First, the pipe is inserted into the inner side of the slide cylinder 116 and pressed downwards, sliding into the guide cylinder 117.

During this period, as the external pipe is continuously inserted into the inner side of the slide cylinder 116, the pressure on the pressure ring 110 gradually increases, thereby driving the pressure ring 110 and each of the insertion rods 111 to move towards the support ring 105. When the external pipe abuts against the limiting ring 118, each of the insertion rods 111 simultaneously abuts against the inner side of the support ring 105. At this time, the multiple springs 114 corresponding to the inner side of each bottom block 112 push the locking block 115 out, retaining the insertion rods 111 inside the support ring 105, completing the locking.
