[0026] The limiting assembly 3 includes a clamping frame 301 and a mounting frame 303. The mounting frames 303 are fixedly installed at the middle of the two symmetrical sides of the second connecting plate 6, and the mounting frames 303 are fixedly installed at the two symmetrical sides of the first connecting plate 2. The bottom of the inner cavity of the mounting frame 303 is fixedly installed with a spring 304, and the top of the spring 304 is fixedly installed with a plug-in block 305.

[0027] The side wall of the clamping frame 301 is symmetrically provided with clamping grooves 302, and the clamping grooves 302 are in a "concave" shape.

[0028] In this embodiment, refer to Figure 1 and Figure 2 As shown, the mounting assembly 4 includes a bolt 401, the first connecting plate 2 is rectangularly threadedly connected to the bolt 401, the side wall of the screwing end of the bolt 401 is provided with a first limiting groove 402, the bolt 401 passes through the side wall of the first connecting plate 2 and is threadedly connected to the second connecting plate 6, the bolt 401 passes through the second connecting plate 6 and extends to the outside, the side of the bolt 401 away from the screwing end of the bolt 401 is threadedly connected to a nut 403, and a second limiting groove 404 is provided on the side wall of the nut 403.

[0029] In this embodiment, refer to Figure 2 and Figure 3 As shown, a clamping groove 302 is slidably installed between the first limiting grooves 402 located in the same vertical direction, and the outer wall of the clamping groove 302 is in contact with the inner wall of the first limiting groove 402;

[0030] When the snap-in slot 302 is inserted into the first limiting slot 402 and the second limiting slot 404, the bolt 401 and the nut 403 are restricted from moving toward both sides, thereby preventing the bolt 401 and the second limiting slot 404 from loosening, thereby preventing the device from loosening and leaking.

[0031] In this embodiment, refer to Figure 2 and Figure 3 As shown, a mounting frame 303 is slidably mounted in the inner wall of the clamping groove 302, the outer wall of the mounting frame 303 contacts the inner wall of the clamping groove 302, the spring 304 is slidably mounted in the inner cavity of the mounting frame 303, the side wall of the mounting frame 303 always contacts the inner wall of the mounting frame 303, and the inner wall of the clamping frame 301 contacts the side walls of the first connecting plate 2 and the second connecting plate 6 respectively;

[0032] The mounting frame 303 limits the vertical movement of the card-joint frame 301 , and the plug-in block 305 limits the horizontal movement of the card-joint frame 301 . The outer wall of the plug-in block 305 is always in contact with the inner wall of the mounting frame 303 , thereby ensuring the plug-in block 305 's ability to limit the card-joint frame 301 .

[0033] Working principle: When in use, firstly, the bolt 401 is used to thread the first connecting plate 2 and the second connecting plate 6, and after the first connecting plate 2 and the second connecting plate 6 are precisely and tightly connected, the second limiting groove 404 is threadedly connected to the bolt 401 from the other end of the bolt 401, and the second limiting groove 404 is used to assist in clamping the first connecting plate 2 and the second connecting plate 6;

[0034] After completion, press the plug-in block 305 on the first connecting plate 2 and the second connecting plate 6, and press the plug-in block 305 into the installation frame 303. At this time, align the snap-in slot 302 on the snap-in frame 301 with the installation frame 303 for plugging, so that the snap-in slot 302 is plugged into the second limiting slot 404 and the first limiting slot 402. At this time, release the pressure on the plug-in block 305. Under the action of the spring 304, the plug-in block 305 will limit the snap-in frame 301 from moving outward. When the snap-in slot 302 is plugged into the first limiting slot 402 and the second limiting slot 404, the path of the bolt 401 and the nut 403 moving toward both sides is limited, thereby avoiding the problem of loosening of the bolt 401 and the second limiting slot 404, which in turn causes the device to loosen and leak.
