[0019] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0020] according to Figure 1-Figure 3As shown, it includes a valve body 1, a mounting sleeve 2 is installed on the outer surface of the valve body 1 near the middle of the top, and the inner wall of the mounting sleeve 2 is provided with through grooves 21 on both sides, a fixing disk 22 is installed on the side surface of the mounting sleeve 2 near the through groove 21, and a fixing plate 23 is installed on the side surface of the mounting sleeve 2 near the bottom of the fixing disk 22, the shape of the fixing plate 23 is L-shaped, and a magnet block 24 is installed on the inner wall of one side of the fixing plate 23.

[0021] A moving rod 3 is slidably arranged inside the fixed plate 22, and a spring 31 is sleeved on the outer surface of the moving rod 3. The moving rod 3 and the spring 31 are arranged inside the through groove 21. One end of the spring 31 is installed on one side of the fixed plate 22, and the other end of the spring 31 is installed on one side of the limit head 32. The limit head 32 is installed on one end of the moving rod 3, and a mounting plate 33 is installed on the other end of the moving rod 3. A hand-held rod 34 is installed on one side of the mounting plate 33.

[0022] The mounting sleeve 2 is internally rotatably connected to the valve stem 4, and the side surface of the valve stem 4 is provided with four groups of limiting holes 41, the top inner wall of the valve body 1 is provided with a through hole near the bottom end of the valve stem 4, and the bottom end of the valve stem 4 passes through the top inner wall of the valve body 1 through the through hole, and the valve 43 is arranged inside the valve body 1, and the four groups of limiting holes 41 are centrally symmetrically arranged with the center point of the valve stem 4 as the center point, the outer diameter of the limiting head 32 is adapted to the inner diameter of the limiting hole 41, and the limiting head 32 is located inside the limiting hole 41 and is movably connected thereto, a valve bolt 42 is installed at the top end of the valve stem 4, and a valve 43 is installed at the bottom end of the valve stem 4.

[0023] When it is necessary to use the valve 43 to close the interior of the valve body 1, the user can first move the corresponding mounting plate 33 and the corresponding moving rod 3 to one side through the two sets of hand-held rods 34, so that the corresponding limit head 32 can move accordingly, so that the limit head 32 can move out from the interior of the limit hole 41. During this process, the corresponding spring 31 will shrink accordingly. When the side surface of the corresponding mounting plate 33 is respectively attached to the side surface of the corresponding magnet block 24 and adsorbed and fixed, the movement of the two sets of moving rods 3 can be stopped. After that, the user can rotate the valve bolt 42 90°, so that the valve stem 4 can rotate accordingly in the interior of the mounting sleeve 2, so that the valve 43 can rotate accordingly in the interior of the valve body 1, so that the valve 43 can rotate from a state parallel to the valve body 1. Until it is in a vertical state with the valve body 1, so that the interior of the valve body 1 can be closed. After that, the user can use two sets of hand-held rods 34 to respectively move the corresponding mounting plate 33 and the corresponding moving rod 3 toward the inner direction of the mounting sleeve 2, so that one side surface of the corresponding mounting plate 33 can be separated from the one side surface of the corresponding magnet block 24. At this time, under the action of the elastic restoring force of the corresponding spring 31, the corresponding limit head 32 can be respectively moved in the direction of the corresponding limit hole 41, so that the corresponding limit head 32 can finally extend into the interior of the corresponding limit hole 41 and perform corresponding limit clamping, so as to realize the self-locking function, thereby effectively solving the problem that the valve stem 4 and the valve 43 are not provided with an effective self-locking structure, so that the valve stem 4 and the valve 43 are easy to rotate at will, thereby affecting the normal use of the valve body 1.
