[0027] The lower clamp body 10 is usually fixed on the rust removal machine; the upper clamp body 1 and the lower clamp body 10 are connected together to form the mounting cavity 8 for accommodating the top or bottom of the oxygen cylinder. The first extension cavity 21 is used for mounting the first extension head 20, the second extension cavity 9 is used for mounting the second extension head 11, and the third extension cavity 23 is used for mounting the third extension head 22. The ejection mechanism can adopt a hydraulic mechanism, a threaded mechanism or other structures capable of controlling the extension amount of the extension head. By adjusting the extension amount of the first extension head 20, the second extension head 11 and the third extension head 22, the clamping center can be effectively adjusted. The first extension head 20, the second extension head 11 and the third extension head 22 are provided because the three endpoints of the first extension head 20, the second extension head 11 and the third extension head 22 can determine a circle. Therefore, the design of the first extension head 20, the second extension head 11 and the third extension head 22 can ensure stable clamping of the cylinder and also adjust the clamping center. The angle between the third extension head 22 and the first extension head 20 is equal to the angle between the third extension head 22 and the second extension head 11, which is designed to facilitate the adjustment of the vertical position of the clamping center; in use, the extension amount of the first extension head 20 and the second extension head 11 is adjusted at the same time to ensure that the extension amount of the first extension head 20 and the second extension head 11 is consistent, then the oxygen cylinder is abutted against the first extension head 20 and the second extension head 11, then the extension amount of the third extension head 22 is adjusted to ensure that the third extension head 22 can contact the oxygen cylinder, and finally the upper clamp body 1 and the lower clamp body 10 are locked and fixed to position the oxygen cylinder.

[0028] In a preferred embodiment, one end of the upper clamp body 1 is hinged to the lower clamp body 10, and the other end of the upper clamp body 1 is detachably connected to the lower clamp body 10.

When the upper clamp body 1 is installed, the hinge rod 2 is passed through the connecting hole 7, and then the hinge rod 2 is locked with the upper clamp body 1 by the first nut 3. At this time, since the rotating ring at the bottom of the hinge rod 2 can rotate around the hinge column 4, the upper clamp body 1 can also rotate relative to the lower clamp body 10. To lock the upper clamp body 1 and the lower clamp body 10, first, the upper clamp body 1 is completely buckled on the lower clamp body 10, the locking rod 17 is rotated so that the locking rod 17 is located in the connecting groove 16, and then the locking rod 17 is fixed with the upper clamp body 1 by the second nut 15.

The first mounting head 6 is designed to facilitate the arrangement of the first locking screw 5, the second mounting head 12 is designed to facilitate the arrangement of the second locking screw 13, and the third mounting head 18 is designed to facilitate the arrangement of the third locking screw. More specifically, the first locking screw 5 and the first mounting head 6 can only rotate relative to each other and cannot move relative to each other. The second locking screw 13 and the second mounting head 12 can only rotate relative to each other and cannot move relative to each other. The third locking screw 19 and the third mounting head 18 can only rotate relative to each other and cannot move relative to each other.

[0034] In a preferred embodiment, the end of the first locking screw 5, the second locking screw 13 and the third locking screw 19 is connected with a nut. The nut is designed to facilitate the rotation of the locking screw. Specifically, during actual use, the locking screw can be rotated by using an open wrench or an internal hexagonal wrench.

[0035] In a preferred embodiment, the angle between the third extension head 22 and the first extension head 20 is 120°, and the angle between the third extension head 22 and the second extension head 11 is 120°. This design makes the angles between the first extension head 20, the second extension head 11 and the third extension head 22 equal. This design facilitates the adjustment of the clamping size without changing the clamping center. Specifically, when the clamping size needs to be changed, the first locking screw 5, the second locking screw 13 and the third locking screw 19 are rotated respectively and the extension amounts of the first extension head 20, the second extension head 11 and the third extension head 22 are ensured to be consistent, so that the clamping center is not changed.
