[0029] like Figures 2 to 4 As shown, the first connecting rods 22 are arranged in an array.

[0030] like Figure 3 As shown, a reinforcing sealing sheet 41 is provided on one side of the hinge between the fixed fan 2 and the movable fan 3 close to the main body 1 .

[0031] like Figure 1 , Figure 2 and Figure 5 As shown, the auxiliary fixing device is a limit clamping seat 5, and the limit clamping seat 5 is detachably connected to the top of the main body 1. A handle is provided on the side of the limit clamping seat 5 away from the main body 1.

[0032] like Figure 2 and Figure 4 As shown, a non-slip pad 6 is connected to the bottom of the main body 1, and the bottom of the non-slip pad 6 is arc-shaped.

[0033] like Figure 2 As shown, the main body 1 is vertically projected into an irregular pentagon, and the top of the main body 1 is a convex right triangle.

[0034] like Figure 2 and Figure 6 As shown, a reinforcement section 321 is provided at one end of the second connecting rod 32 away from the rotating member 31 .

[0035] Principle and operation process

[0036] The utility model controls the movable fan 3 by lifting or pressing down, thereby realizing the pressure-blocking of the water supply and drainage pipes. The main principle is: during the process of pressing down the main body 1, since the movable fan 3 and the rotating member 31 on the main body 1 are fixed in position, as the main body 1 is pressed down, the integral connecting rod composed of the two second connecting rods 32 rotates counterclockwise around the rotating member 31 on the side close to the main body 1. Since the main body 1 is fixed, the integral connecting rod composed of the second connecting rods 32 will rotate counterclockwise around the rotating member 31, and at the same time, an outward expansion force is generated, and the side close to the movable fan 3 will push the movable fan 3 away from the main body 1. At the same time, since the rotating member 31 is rotationally connected to the main body 1 and the movable fan 3, the two second connecting rods 32 are also directly rotationally connected, so there will be no jamming during the process. When the main body 1 is pressed down to contact with the bottom of the pipe, the movable fan 3 is fully opened. The sealing strips 4 on the movable fan 3 and the fixed fan 2 will cooperate with the movable fan 3 and the fixed fan 2 to complete the sealing. At the same time, the reinforced sealing sheet 41 arranged on the side close to the main body 1 will further seal the hinge of the movable fan 3 and the fixed fan 2, thereby realizing the pressure sealing of the water supply and drainage pipes. The limit holder 5 above the main body 1 can also be stuck in the protruding pipe of the three-way pipe according to the size to temporarily fix the entire device, and cooperate with the anti-slip pad 6 at the bottom of the main body 1 to prevent the water pressure from pushing the device to displace and getting stuck in the water pipe and unable to be removed. When removing the device, it can be easily removed by pulling the handle on the limit holder 5; designing the main body 1 into an irregular trapezoid with a protruding right-angled triangle on the top can save more space and reduce the overall volume of the device.

[0037] Although the specific implementation methods of the utility model are described above in conjunction with the accompanying drawings, it is not intended to limit the scope of protection of the utility model. On the basis of the technical solution of the utility model, various modifications or deformations that can be made by technical personnel in this field without creative work are still within the scope of protection of the utility model.
