Fig. 1 to 3 show a disassembling tool 2 for a high-pressure gas cylinder cap of the present invention, which comprises a hook portion 21 and a handle 22, wherein the hook portion 21 has a hook groove 211, and two sides of a notch of the hook groove 211 are respectively a short arm 212 and a long arm 213; the handle 22 is connected to the end of the long arm 213, the handle 22 and the short arm 212 are respectively located at two sides of the long arm 213, and the angle between the handle 22 and the long arm 213 is 90-180 °.

This scheme provides a simple effectual extracting tool and comes the auxiliary operation. The hooking and buckling part 21 is used for buckling from the opening 12 along the outer wall of the bottle cap 11 in the circumferential direction of the bottle cap 11, the hooking groove 211 is clamped at the edge of the opening 12 after buckling, the short arm 212 is clamped at the inner side of the bottle cap 11, the long arm 213 is clamped at the outer side of the bottle cap 11, and the hooking and buckling part 21 with the structure can be stably clamped at the side surface of the bottle cap 11. In the aspects of convenience, practicability and labor saving, the handle 22 is arranged at the tail end of the long arm 213, the handle 22 is convenient for the hand to grasp and force along the circumferential direction of the bottle cap 11, and the force arm is also prolonged; the handle 22 and the short arm 212 are respectively positioned at two sides of the long arm 213, which can ensure that the handle 22 is protruded out of the bottle cap 11 after the short arm 212 is buckled into the bottle cap 11 without interference; and because the bottle cap 11 needs to be rotated circumferentially, the angle between the handle 22 and the extension arm 213 is 90 ° to 180 ° so that the force applied to the handle 22 by the user is approximately tangential to the bottle cap 11, thereby achieving a further labor-saving effect. In the aspect of preventing the valve from being opened by mistake, the short arm 212 transversely stretches into the bottle cap 11 along the wall of the bottle cap 11, and the length of the short arm 212 is shorter, so that the short arm is farther from a bottle valve hand wheel protected at the middle part of the cap, and the effect of well preventing the gas from leaking due to the fact that the hand wheel of the bottle valve is touched by mistake can be achieved.

Preferably, the long arm 213 is formed in an arc shape, and since the outer surface of the cap 11 is generally cylindrical, the arc-shaped long arm 213 can be more easily attached to the long arm 213, and thus, a phenomenon such as slipping is not likely to occur during use. The long arm 213 is selected to have a circular arc shape, and the central angle of the long arm 213 is 60 ° to 180 °, and when the central angle is 60 ° or more, the long arm 213 can cover a wide range, and can be applied to the cap 11 having a size not greatly different from that of the long arm 213. However, when the corresponding central angle is greater than 180 °, the length of the long arm 213 is too long and is strongly limited by the size of the cap 11, and the cap 11 cannot be used once the diameter of the cap 11 is larger than the diameter of the long arm 213. In addition, the length of the long arm 213 is preferably between 60mm and 150mm in consideration of the size of most existing caps 11.

Specifically, the buckling part 21 is in the shape of a flat rod bent laterally, the wider side surface of the buckling part 21 is used for contacting with the cylinder cap 11 of the high-pressure gas cylinder 1, and the flat rod is not easy to roll and slide away after being attached to the cylinder cap 11; the handle 22 is round and rod-shaped for better hand-gripping experience. The thickness of the hooking part 21 is preferably 3mm to 10mm, and the diameter of the handle 22 is preferably 6mm to 20 mm.

Or, the hook part 21 and the handle 22 may be both in the shape of a round rod, and during manufacturing, the same rod-shaped material may be directly deformed, so that the manufacturing cost is lower and the manufacturing is simpler.

In the selection of material, collude knot portion and handle 22 and be stainless steel or copper spare, these two kinds of material intensity height and be difficult to rust, are fit for as the extracting tool of repetitious long-term use many times.

The use process of the disassembling tool 2 for the cylinder cap of the high-pressure gas cylinder in the embodiment is as follows:

the notch side direction of the clamping groove in the hooking part 21 is buckled at the edge of the opening 12 on the bottle cap 11 of the high-pressure gas bottle 1, when the high-pressure gas bottle needs to be unscrewed anticlockwise, the long arm 213 and the handle 22 face the anticlockwise direction of the bottle cap 11, the short arm 212 is abutted against the inner side of the bottle cap 11, the long arm 213 is abutted against the outer side of the bottle cap 11, and the bottle cap 11 can be unscrewed by holding the handle 22 with a hand and exerting force in the anticlockwise direction.
