The whole operation process is simple and fast, and the efficiency is improved.

[0023] Embodiment 2

[0024] See also Figure 1-Figure 5On the basis of the first embodiment, the positions of the two identical components arranged inside the card connection box 2 are symmetrical, two arc grooves 3 are provided inside the card connection box 2, the fastening clip 4 is slidably connected to the inside of the arc groove 3, the rectangular plate 5 is located outside the card connection box 2, and rectangular slide grooves are provided at both ends of the inner wall of the arc groove 3, and a pressure plate 8 is slidably connected to the inside of the rectangular slide groove. Two symmetrically distributed springs 9 are fixedly connected between the pressure plate 8 and the inner wall of the rectangular slide groove, and the arc groove 3 and the inside of the two rectangular slide grooves are interconnected, one end of one rectangular plate 5 close to the middle of the card connection box 2 is fixedly connected to two connecting plates 2 7 that are far away from each other and symmetrically distributed, and the other rectangular plate 5 is fixedly connected to one end close to the middle of the card connection box 2 with two connecting plates 6 that are far away from each other and symmetrically distributed, one end of the connecting plate 2 7 is clamped with the inside of the connecting plate 6, and a circular groove 12 is provided inside the connecting plate 6. Circular groove 2 13, slot 1 and slot 2, one end of the connecting plate 2 7 is fixedly connected with an insert block 14, three evenly distributed springs 2 10 and a slide bar 11, the spring 2 10 is sleeved on the outer wall of the slide bar 11, one end of the spring 2 10 is fixedly connected to one end of the inner wall of the circular groove 12, the slide bar 11 is slidably connected to the inner wall of the circular groove 2 13, one end of the insert block 14 is provided with a fan-shaped groove, the block 16 is rotatably connected to the inside of the fan-shaped groove, an elastic member 15 is fixedly connected between one end of the block 16 and one end of the inner wall of the fan-shaped groove, the insert block 14 is clamped with the inside of the slot 1, the block 16 is slidably connected with the inside of the slot 2, the inside of the connecting plate 1 6 is slidably connected with an adjusting member 17, one end of the adjusting member 17 is located outside the connecting plate 1 6, the bottom end of the adjusting member 17 is movably connected to the top of the block 16, the cross section of the clamping member 18 is convex, and the clamping member 18 is composed of two hollow circular blocks.

[0025] The elastic force generated by the three springs 2 10 is greater than that of the two springs 1 9, that is, before the pipeline is installed, each spring 1 9 is in a compressed state. The pipeline is clamped between the clamping box 2 and the clamping piece 18, and then the two rectangular plates 5 are pushed to the middle position of the clamping box 2 at the same time, then the connecting plate 2 7 will be displaced into the interior of the connecting plate 1 6. At the same time, each spring 2 10 is compressed, and it will eventually be completely located in the inner cavity of the circular groove 12. The slide bar 11 slides synchronously along the inner wall of the circular groove 2 13. The setting of the slide bar 11 prevents the spring 2 10 from deflecting during the compression process, ensuring the stability during the change process. The plug 14 is synchronously displaced into the interior of the card slot 1. During this process, the card block 16 shrinks to the inside of the fan-shaped groove, and the elastic member 15 is compressed. When the card block 16 moves to the bottom of the card slot 2, the card block 16 is no longer affected by the card slot The spring 19 is still in a compressed state at this time to enhance the clamping effect. To release the pipeline, you only need to press the two adjusting members 17, and the bottom end of the adjusting member 17 presses the top end of the block 16 to return it to the inside of the second card slot. At the moment when the block 16 is flipped to the inside of the second card slot, the external force on each spring 10 disappears and gradually restores its deformation. Then the two fastening clamps 4 will release the restraint on the pipeline. The entire operation process is simple and fast, which improves efficiency.

[0026] In actual use, the pipeline is clamped between the clamping box 2 and the clamping piece 18, and then the two rectangular plates 5 are pushed toward the middle position of the clamping box 2 at the same time, then the connecting plate 2 7 will be displaced into the interior of the connecting plate 1 6. At the same time, each spring 2 10 is compressed, and it will eventually be completely located in the inner cavity of the circular groove 12. The slide bar 11 slides synchronously along the inner wall of the circular groove 2 13. The setting of the slide bar 11 prevents the spring 2 10 from deflecting during the compression process, ensuring the stability during the change process. The plug-in block 14 is synchronously displaced into the interior of the slot 1. In this process, the block 16 shrinks to the inside of the fan-shaped groove, and the elastic member 15 is compressed. When the block 16 is displaced to the bottom of the slot 2, the block 16 is no longer restricted by the inner wall of the slot 1, and the elastic member 15 recovers its deformation and displaces the block. 16 is flipped to the inside of the second card slot. At this time, one side of the block 16 contacts with the inside of the second card slot and is stuck. When the hand is released, the plug block 14 shall not move in the opposite direction. Under the connection of the rectangular plate 5, the two fastening clamps 4 will also move synchronously and fasten and clamp the pipeline. At this point, the installation of the pipeline is completed. The spring 1 9 is still in a compressed state at this time to enhance the clamping effect. To release the pipeline, you only need to press the two adjusting members 17, and the bottom end of the adjusting member 17 presses the top of the block 16 to return it to the inside of the second card slot. At the moment when the block 16 is flipped to the inside of the second card slot, the external force on each spring 10 disappears and gradually recovers its deformation. Then the two fastening clamps 4 will release the restraint on the pipeline. The entire operation process is simple and fast, which improves efficiency.
