[0027] The protective cover 9 is fixedly mounted on the outer surface of one side of the cylinder 6, the threaded hole 10 is opened in the middle of the outer surface of the protective cover 9 away from the end of the cylinder 6, and the second through hole 19 is opened in the middle of the outer surface of the cylinder 6 close to the protective cover 9; the number of sliding holes 15, guide rods 16, compression springs 17 and limit blocks 18 are all two groups, and the two groups of sliding holes 15 are opened at the upper and lower ends of the outer surface of the cylinder 6 close to the protective cover 9. The guide rod 16 passes through the sliding hole 15, and the outer wall of the guide rod 16 is slidably connected to the sliding hole 15. The tooth plate 14 is located in the cavity 7, and the two groups of guide rods 16 are fixedly mounted on the upper and lower ends of the outer surface of one side of the tooth plate 14; the compression spring 17 is movably sleeved on the outer wall of the guide rod 16, and the outer surface of one end of the compression spring 17 is fixedly connected to the outer wall of the cylinder 6, and the other end of the compression spring 17 The outer surface is fixedly connected to the outer surface of one side of the limit block 18, and the limit block 18 is fixedly mounted on the outer surface of one end of the guide rod 16 away from the tooth plate 14. The outer wall of the guide rod 16 and the sliding hole 15 are slidingly connected, and the outer surface of one side of the limit block 18 is elastically connected to the outer wall of the cylinder 6 through a compression spring 17; the connecting rod 13 is fixedly mounted on the middle part of the outer surface of one side of the tooth plate 14, and the outer surface of one end of the screw 11 is connected to one end of the connecting rod 13. A sealed bearing is provided between the screw 11 and the connecting rod 13, and the screw 11 is rotatably connected to the connecting rod 13 through a sealed bearing, and the knob 12 is fixedly mounted on the outer surface of one end of the screw 11 away from the connecting rod 13; the outer wall of the screw 11 and the threaded hole 10 are threadedly connected, and the outer surface of one side of the tooth plate 14 is meshed with the outer surface of one side of the gear 5.

The valve body 1, valve stem 2 and hand wheel 3 described in the text are all prior art and can be effectively known to those skilled in the art. The specific details will not be repeated here. The anti-misrotation component 4 is provided, and the gear 5 is fixed to the outer wall of the upper part of the valve stem 2 through the provided gear 5. When the hand wheel 3 is rotated, the gear 5 can be driven to rise and fall.

When the tooth plate 14 is engaged with the gear 5, the compression spring 17 is in a squeezed state, and the axial tension of the screw 11 is enhanced by releasing the reaction force, thereby increasing the friction and generating a resistance torque, thereby preventing loosening after the threaded connection. By limiting the gear 5 by the tooth plate 14, the handwheel 3 can be prevented from being rotated, thereby improving safety during use.
