When the handle 201 slides toward the disk 202, the limit block 202a passes through the first slide groove 201b to realize the synchronous rotation between the handle 201 and the rotating rod 101. If the operating rod A does not need to be operated, the handle 201 is slid to let the limit block 202a slide out of the first slide groove 201b; when the operating rod A is not operated, the rotation of the handle 201 is invalid, which can prevent the operator from accidentally touching the valve switch.

[0042] A second elastic member 203 is disposed on the end surface of the disk 202 , and the second elastic member 203 is sleeved on the outer wall of the operating rod A. The other end of the second elastic member 203 is connected to the lower surface of the handle 201 .

[0043] Among them, a second elastic member 203 is installed between the disk 202 and the handle 201. The second elastic member 203 is a compression spring. When the operating rod A needs to be rotated, the operator can push the handle 201 in the direction of the disk 202, so that rotating the handle 202 can drive the operating rod A to rotate. After releasing the handle, the second elastic member 203 can automatically reset the handle 201 to prevent accidental operation.

[0044] An annular groove 201c is formed on the end surface of the handle 201, and an array of first grooves 201c-1 are formed on the inner wall of the annular groove 201c.

[0045] A sleeve 204 is arranged inside the annular groove 201c, a third limiting groove 204a is arranged in an array on the inner wall of the sleeve 204, and a slider A1 which can slide along the inside of the third limiting groove 204a is arranged in an array on the outer wall of the operating rod A.

[0046] The outer wall of the sleeve 204 is provided with a second groove 204b in array, the inner wall of the second groove 204b is rotatably provided with a push rod 205, the outer wall of the push rod 205 is connected to a third elastic member 206, and the other end of the third elastic member 206 is connected to the inner wall of the second groove 204b.

[0047] Among them, a ring groove 201c is dug on the side of the handle 201 away from the disc 202, and the inner wall array of the ring groove 201c is provided with a first groove 201c-1, and in this scheme, the first groove 201c-1 array is provided with three; and a slider A1 is fixedly installed on the outer wall of the operating rod A, and the slider A1 is arrayed on the outer wall of the operating rod A, and the third limiting groove 204a on the inner wall of the sleeve 204 can allow the slider A1 to slide; the outer wall array of the sleeve 204 is provided with a second groove 204b, and the inner wall of the second groove 204b is rotatably provided with a push rod 205, and the other end of the push rod 205 abuts against the inner wall of the first groove 201c-1, and a third elastic member 206 is connected between the inner wall of the second groove 204b and the outer wall of the push rod 205. The third elastic member 206 is a compression The advantage of this design is that when the handle 201 is turned by mistake, the first groove 201c-1 on the inner wall of the handle 201 will push the push rod 205 to drive the drag barrel 204 to rotate. At the same time, because the drag barrel 204 and the operating rod A cooperate with the third limiting groove 204a through the slider A1, the drag barrel 204 will drive the operating rod A to rotate, and the direction of rotation is the direction of valve closing, and the valve will not be opened by mistake. If it is turned to the direction of valve opening, the first groove 201c-1 on the inner wall of the handle 201 will squeeze the push rod 205 to rotate, and the push rod 205 will slide out of the first groove 201c-1 and enter the next groove 201c-1, thereby realizing the idling of the handle 201, and will not drive the operating rod A to rotate, and the valve will not be affected.

[0048] The outer wall array of the handle 201 is provided with soft hair 201d.

[0049] The outer wall array of the handle 201 is provided with soft hair 201d, which increases the operator's comfort in operating the handle 201. The soft hair 201d can also increase the friction between the palm and the handle 201, making the operation more convenient.

[0050] In summary, when the operator needs to rotate the operating rod A, the sleeve 204 is pushed to synchronously drive the handle 201 to move in the direction of the disc 202, and then the limit block 202a enters the first slide groove 201b, and then the handle 201 is rotated to drive the operating rod A to rotate normally. When it is not necessary to rotate, the handle 201 is released, and the second elastic member 203 will automatically reset the handle 201.
