The surface of the first fixing plate 45 is connected with a pulling plate 49, and a layer of anti-skid grains are arranged on the surface of the pulling plate 49; in operation, the pulling plate 49 is connected to the surface of the first fixing plate 45, so that the first fixing plate 45 can be pulled by a user, and the valve body 1 can be assembled by the user.

An alignment block 491 is connected to the surface of the connecting plate 47, and the alignment block 491 is aligned with the first fixing plate 45; when the first pin hole 46 and the second pin hole 48 are aligned, the spring 43 is not stable and is not convenient for the user to align, and the aligning block 491 is connected to the surface of the connecting plate 47, so that the user can directly and mutually abut against the aligning block 491 at one end of the first fixing plate 45, and then the first pin hole 46 and the second pin hole 48 can be aligned.

The surface of the valve body 1 is provided with a plurality of alignment lines 492, and the alignment lines 492 are parallel to the side surface of the limit plate 44; when the mechanism is used again, the user only needs to use a wrench to finely adjust the nut 3 to the corner position aligned with the limiting plate 44 by observing the position of the alignment line 492, so that the mechanism is convenient to realize.

A layer of rubber pad 493 is arranged on the surface of the limiting plate 44; when the nut locking device works, the rubber pad 493 is made of soft materials, so that the rubber pad 493 is arranged on the surface of the limiting plate 44, and the locking error of the limiting plate 44 on the nut 3 can be increased.

A second fixing plate 494 is connected to the surface of the position limiting plate 44, the second fixing plate 494 and the first fixing plate 45 are symmetrical along the central axis of the moving ring 42, and a pulling block 495 is connected to the surface of the second fixing plate 494; in operation, when the limiting plate 44 needs to be pulled to separate from the engaging position, the pulling block 495 and the pulling plate 49 can make the pulling force applied to the limiting plate 44 more uniform, so that the movement of the limiting plate 44 is more stable.

Example two

Referring to fig. 5, in a first comparative example, as another embodiment of the present invention, a plurality of balls 496 are disposed on an inner circumferential surface of the moving ring 42, and the moving ring 42 is connected to the valve body 1 through the balls 496 in a rolling manner; in operation, when the shift ring 42 moves on the surface of the valve body 1, the friction between the shift ring 42 and the valve body 1 can be greatly reduced by the balls 496, thereby reducing the running wear of the mechanism.

According to the working principle, when the valve body 1 needs to be disassembled, the limiting plate 44 and the nut 3 are mutually clamped, meanwhile, the limiting plate 44 is limited in rotation by the combined action of the valve body 1 and the guide rod 41 through the moving ring 42, meanwhile, the spring 43 is limited in elasticity to the limiting plate 44 through the moving ring 42, so that the limiting plate 44 has stable limited rotation limitation to the nut 3, at the moment, a user only needs to use one wrench to rotate the screw 2, the disassembly can be completed, the problem that the disassembly efficiency is greatly influenced due to the fact that the user needs to prepare two wrenches in the disassembly process and needs to mutually match and exert force by two hands of the user is avoided, the spring 43 is compressed, when the first pin hole 46 is aligned with the second pin hole 48, the self-locking of the mechanism can be completed by the aid of a bolt penetrating through the first pin hole 46 and the second pin hole 48, then the user normally uses the nut 3 to assemble the valve body 1 through the limiting plate 44, namely, the nut 3 can be assembled on the valve body 1, and the nut 3 can not be clamped by the bolt, and the nut 3 can not be assembled in the same type of the nut 3, and the nut 3 can not be assembled in the same type when the valve body 1 and the assembly work of the valve body 1 is required to be assembled; when a user aligns the first pin hole 46 and the second pin hole 48, the spring 43 is not stable due to the elastic force of the spring, and thus it is not convenient for the user to align the pin holes, and the aligning block 491 is connected to the surface of the connecting plate 47, so that the user can directly abut one end of the first fixing plate 45 against the aligning block 491, and then the alignment of the first pin hole 46 and the second pin hole 48 can be completed.
