Furthermore, the inner walls of the first tooth groove and the second tooth groove are covered with a layer of anti-skid rubber mat. The petal handle is effectively prevented from slipping, and opening and closing operations are facilitated.
The handle is the telescopic link, and the telescopic link includes a fixed section of thick bamboo and the telescopic cover in upper end and locates the movable rod of a fixed section of thick bamboo lower part, and a fixed section of thick bamboo lower part pipe wall is equipped with first screw hole, carries out relatively fixed through twisting the first screw hole of bolt to a fixed section of thick bamboo and movable rod. When the oxygen cylinder valve switch needs to be opened or closed, the telescopic rod can be extended to the longest length, so that labor is saved. When the oxygen cylinder valve opening and closing tool is not needed, the telescopic rod is contracted, and the oxygen cylinder valve opening and closing tool is convenient to store.
Furthermore, the movable rod is provided with a plurality of second threaded holes at intervals along the length direction of the movable rod, the bolt can be simultaneously inserted into the first threaded hole and the second threaded hole, and the bolt is simultaneously in threaded connection with the fixed cylinder and the movable rod. The bolt can insert first screw hole and second screw hole simultaneously, makes fixed section of thick bamboo be connected more firmly with the movable rod.
Compared with the prior art, the utility model has the advantages that:
1. the utility model discloses the matched stack structure that sets up first tooth's socket and second tooth's socket and the shape and the size phase-match of petal handle, go into the matched stack structure of first tooth's socket and second tooth's socket with petal handle card in, hold the handle and promote the petal handle and rotate to open or close oxygen cylinder valve switch. The lever principle is utilized to solve the problem that the original manual switching mode wastes time and labor. Not only saves labor, but also improves the convenience of opening and closing.
2. The other end of first centre gripping arm passes through the fastener with the other end of second centre gripping arm and can dismantle the connection. The opening between the first clamping arm and the second clamping arm can be opened through the fastener, and the petal handle is conveniently clamped into the assembly structure of the first tooth groove and the second tooth groove.

Detailed Description
In order to make the aforementioned objects, features and advantages of the present invention more clearly understood, the following detailed description of the present invention, taken in conjunction with the accompanying drawings and the detailed description, is given in a non-limiting manner.
As shown in fig. 1 to 3, the oxygen cylinder valve opening and closing tool of the present embodiment includes a handle 1, a first clamping arm 2 and a second clamping arm 3, wherein one end of the first clamping arm 2 and one end of the second clamping arm 3 are both mounted on the handle 1, and the other end of the first clamping arm 2 is detachably connected to the other end of the second clamping arm 3 through a fastener 4; the first clamping arm 2 is provided with a first tooth groove 21, the second clamping arm 3 is provided with a second tooth groove 31, and the matched structure of the first tooth groove 21 and the second tooth groove 31 is matched with the shape and the size of the petal handle 5. The first clamping arm 2 and the second clamping arm 3 are both made of elastic materials. The inner walls of the first tooth groove 21 and the second tooth groove 31 are covered with a layer of anti-skid rubber mat.
The fastening piece 4 comprises a screw 41 and a wing nut 42 matched with the screw 41, the first clamping arm 2 is connected with the screw 41, the second clamping arm 3 is provided with a through hole 32, the wing nut 42 is arranged around the through hole 32 and is rotatably connected with the second clamping arm 3, and the screw 41 can simultaneously penetrate through the through hole 32 and the wing nut 42. The second clamping arm 3 is provided with a mounting groove 33, the inner wall of the mounting groove 33 is provided with an annular groove, the outer surface of the butterfly nut 42 is protruded with a sliding block 43, the butterfly nut 42 can be rotatably inserted into the mounting groove 33, and the sliding block 43 can be slidably inserted into the annular groove; the mounting groove 33 communicates with the through hole 32.
For the use of this example, reference is made to the following steps:
when the external flap type oxygen valve needs to be opened, first, the screw 41 is disengaged from the butterfly nut 42. Next, the distance between the first holding arm 2 and the second holding arm 3 is enlarged, and the petal handle 5 is clipped into the first holding arm 2 and the second holding arm 3. Because there is elasticity between first centre gripping arm 2 and the second centre gripping arm 3, not only the petal handle 5 card of being convenient for is gone into, and the back is gone into to the card moreover, and first centre gripping arm 2 and second centre gripping arm 3 can compress tightly it under the elastic action, prevent that petal handle 5 from breaking away from. And thirdly, the screw 41 simultaneously penetrates through the through hole 32 and the butterfly nut 42, and the butterfly nut 42 is rotated to reduce the distance between the first clamping arm 2 and the second clamping arm 3, so that the first clamping arm 2 and the second clamping arm 3 are tightly attached to the petal handle 5. Finally, the length of the handle 1 is adjusted, the handle 1 is held by one hand to rotate anticlockwise, the first clamping arm 2 and the second clamping arm 3 drive the petal handle 5 to rotate synchronously, and then the external valve type oxygen valve is opened by rotating anticlockwise.
Similarly, one hand holds the handle 1 to rotate clockwise, so that the first clamping arm 2 and the second clamping arm 3 drive the petal handle 5 to rotate synchronously, and then the external valve type oxygen valve is closed clockwise.
