In one embodiment, the sliding block 52 and the positioning groove 310 have arc-shaped cross-sections that cooperate with each other. After the slider 52 is accommodated in the positioning groove 310 , the self-locking function can be achieved due to its arc-shaped cross section, preventing the slider 52 from moving on the positioning block 31 .

In the embodiment shown in the figure, the transition slope 32 is located on a side of the positioning block 31 away from the opening 102 of the upper shell 10 . In an embodiment, it is more preferable that the transition slope 32 is located on a side of the positioning block 31 close to the opening 102 of the upper shell 10 . Generally, when operating with one hand, since the force direction of the upper shell 10 is opposite to that of the dial 50 during the process of moving the dial 50 to seal the valve body 60, if the transition slope 32 is set close to the opening 102 side, when the toggle block 50 is moved, the force direction of the toggle block 50 is away from the side where the upper shell 10 is provided with the opening 102, and the force direction of the upper shell 10 is toward the side of the opening 102, thus preventing The state that the upper case 10 is clamped on the valve body 60 changes, so as to avoid the position where the upper case 10 engages with the valve body 60 from changing.

Referring to FIG. 3 at the same time, the lower surface 302 of the pressure plate 30 extends downwards near the opening 102 of the upper shell 10 to form an anti-loosening arm 33 . The anti-loosening arm 33 is used to prevent the pipe plug from falling off from the valve body 60 in the opposite direction along the upper shell 10 and the valve body 60 when the gasket 40 seals the valve body 60 . As shown in FIG. 4 , when the pressure plate 30 is pushed against to make the gasket 40 seal the valve body 60 , the anti-loosening arm 33 blocks one side of the valve body 60 . At this time, because the valve body 60 is stuck in the gap 202 of the lower cover 20, the pipe plug cannot move up and down; The left side of the valve body 60 resists the end of the gap 202 of the lower cover 20, and the right side of the valve body 60 is blocked by the anti-off arm 33, so the pipe plug cannot move in the left and right direction. In this way, the pipe plug is fixed in all directions, which ensures the sealing effect between the gasket 40 and the valve body 60 . It can be understood that in other embodiments, the movement restriction of the pipe plug in various directions can also be realized by, for example, the tight fit between the gasket 40 and the valve body 60 , and the tight fit between the lower cover 20 and the valve body 60 .

As shown in FIG. 3 , a through hole 303 is provided at the corner of the pressing plate 30 . The upper case 10 is provided with a guide post 11 , the guide post 11 passes through the through hole 303 of the pressing plate 30 , and the pressing plate 30 is elastically arranged between the upper case 10 and the lower cover 20 through the elastic member 12 . The elastic member 12 is disposed between the lower cover 20 and the pressure plate 30 , and provides elastic force against the pressure plate 30 upwards. After the lower cover 20 is combined with the upper shell 10 , the pressure plate 30 tends to approach the upper shell 10 upwards. It can be understood that the elastic member 12 can also be disposed between the pressing plate 30 and the upper shell 10 , and provide elastic force to pull the pressing plate 30 upward. In addition, the guide post 11 can also be arranged on the lower cover 20 , or can be arranged on the upper case 10 and the lower cover 20 at the same time. When the guide post 11 is disposed on the upper case 10 or the lower cover 20, it can be suspended.
