[0089] Among them, through the setting of the compression spring 532, a force is applied to the ejection of the sliding column 531, enabling the sliding column 531 to insert into the interior of the insertion groove 510 for limiting, and at the same time, the sliding column 531 can also slide upward by compression and move into the interior of the installation groove 520.

[0090] In some embodiments of the present utility model, the limiting device 600 includes:

[0091] A U-shaped limiting plate 610, which is fixed to the top of the upper clamping plate 420;

[0095] The working method of the present utility model:

[0096] When it is necessary to limit the ball valve arm 200, press the upper clamping plate 420 to make the upper clamping plate 420 rotate and tilt up, so that the coil spring 440 stores energy. Then rotate the ball valve arm 200 into the interior of the limiting groove 450, and release the upper clamping plate 420 to make the sliding column 531 insert into the interior of the insertion groove 510 to position the ball valve arm 200;

[0097] When it is not necessary to completely lock the ball valve arm 200, rotate the threaded sleeve 620, and the threaded sleeve 620 will rotate to the lower part of the threaded rod 533. When the ball valve arm 200 moves, it will squeeze the sliding column 531, causing the sliding column 531 to rise under the action of the inclined plane and squeeze the compression spring 532, so that the sliding column 531 disengages from the insertion groove 510, and the ball valve arm 200 can slide normally;

[0098] When it is necessary to completely lock the ball valve arm 200, rotate the threaded sleeve 620, the threaded sleeve 620 moves to the upper part of the threaded rod 533, and contacts the U-shaped limiting plate 610, so that the sliding column 531 cannot be separated from the plug-in groove 510, and the lower side of the U-shaped limiting plate 610 is set as a vertical surface, and limits the rotation of the upper clamping plate 420, so that the ball valve arm 200 is completely locked.
