[0032] Example:

[0033] The following is combined with Figure 1-3 The utility model is described in further detail.

[0034] See also Figure 1-3 The utility model provides a technical solution: a connection and fixing structure of a row of pipes, including a placement rack 1, a plurality of tapered holes 2 are opened on the surface of the placement rack 1, and a pipe body 3 is inserted into the inner wall of the plurality of tapered holes 2. A clamping assembly 4 is fixedly connected to the upper surface of the placement rack 1, and the clamping assembly 4 includes a first fixing rod 401, two telescopic rods 402, a second fixing rod 403, a plurality of clamping plates 404 and two first springs 405. Limiting assemblies 5 are respectively arranged on both sides of the two telescopic rods 402. The limiting assembly 5 includes two supporting plates 501, a rotating shaft 502, a rocker plate 503, a clamping block 504, a torsion spring 505 and a through groove 506. A plurality of limiting grooves 6 are opened on the side of the telescopic rod 402. By setting a plurality of tapered holes 2, it is convenient to place a plurality of pipe bodies 3 at equal intervals. By setting the clamping assembly 4, under the action of the two telescopic rods 402, the second fixing rod 403 drives the plurality of clamping plates 404 to clamp and fix the plurality of pipe bodies 3 respectively, thereby improving the connection and fixing effect.

[0035] Specifically, the first fixed rod 401 is fixedly connected to the upper surface of the placement rack 1, the two telescopic rods 402 are fixedly connected to the surface of the first fixed rod 401, the second fixed rod 403 is fixedly connected to the other ends of the two telescopic rods 402, and multiple clamping plates 404 are fixedly connected to the surfaces of the first fixed rod 401 and the second fixed rod 403, and two first springs 405 are respectively arranged on the inner walls of the two telescopic rods 402.

[0036] By adopting the above technical solution and providing two telescopic rods 402 , it is convenient for the second fixing rod 403 to drive the plurality of clamping plates 404 to clamp and fix the plurality of tube bodies 3 respectively, thereby improving the connection and fixing effect.

[0037] Specifically, the two support plates 501 are fixedly connected to the sides of the telescopic rod 402, the rotating shaft 502 is penetrated through the surface of the support plate 501, the rocker 503 is rotatably connected to the surface of the rotating shaft 502, the block 504 is fixedly connected to one end of the rocker 503, the torsion spring 505 is sleeved on the surface of the rotating shaft 502, and the through groove 506 is opened on the surface of the telescopic rod 402.

[0038] By adopting the above technical solution, by setting the clamping block 504, the torsion spring 505 drives the seesaw 503 and the clamping block 504 to be clamped on the inner wall of the limiting groove 6, so as to facilitate unidirectional limitation of the length of the telescopic rod 402, so that the clamping plate 404 clamps and fixes the tube body 3, and by pressing the other end of the seesaw 503, it is easy to drive the clamping block 504 to separate from the limiting groove 6. Under the action of the first spring 405, the second fixing rod 403 can drive multiple clamping plates 404 to automatically separate from the surface of the tube body 3.

[0039] Specifically, a plurality of positioning protrusions 7 are fixedly connected to the back of the placement rack 1 , and a plurality of positioning grooves 8 are formed on the surface of the placement rack 1 .

[0040] By adopting the above technical solution and providing a plurality of positioning protrusions 7 and a plurality of positioning grooves 8, it is convenient to position two placement racks 1 placed side by side.

[0041] Specifically, the back and the surface of the placement rack 1 are fixedly connected with magnetic blocks 9 , and the arc surface of the clamping plate 404 matches with the tube body 3 .

[0042] By adopting the above technical solution and providing the magnetic block 9, it is convenient to connect a plurality of racks 1 side by side.

[0043] The working principle of the utility model is as follows: when in use, a plurality of tube bodies 3 are inserted into the inner wall of the tapered hole 2, and then the second fixing plate is pressed, and under the action of the two telescopic rods 402, the second fixing rod 403 drives the plurality of clamping plates 404 to clamp the plurality of tube bodies 3 respectively, and then the torsion spring 505 drives the seesaw plate 503 and the clamping block 504 to clamp the inner wall of the limiting groove 6, and the length of the telescopic rod 402 is limited in one direction, so that the clamping plate 404 clamps and fixes the tube body 3. When it is necessary to insert a plurality of tube bodies 3, When the two placement racks 1 are connected side by side, the two placement racks 1 are positioned by multiple positioning protrusions 7 and multiple positioning grooves 8. Under the action of the magnetic block 9, the multiple placement racks 1 are connected side by side. When the tube body 3 needs to be taken out, the other end of the rocker 503 is pressed to drive the card block 504 to disengage from the limiting groove 6. Under the action of the first spring 405, the second fixing rod 403 drives the multiple clamping plates 404 to automatically disengage from the surface of the tube body 3, thereby releasing the clamping fixation of the tube body 3 and taking out the tube body 3.
