[0002] In the related technical field, composite gas cylinders are widely used to store liquid gas under pressure, mainly including the following types: all-metal gas cylinders, metal liner fiber winding gas cylinders, metal liner fiber full winding gas cylinders, and non-metal liner full winding gas cylinders. Among them, the first and second types of gas cylinders are difficult to meet the requirements of unit mass hydrogen storage density due to their large weight; and the third type of gas cylinder has high cost, so the fourth type of gas cylinder shows better application prospects. In the processing of composite gas cylinders, assembly tools are needed.

[0003] However, there are still some deficiencies in the prior art. First, a significant problem is that we may encounter various diameters of bottles in the actual production process. The size difference of these bottles may lead to reduced production efficiency, as the equipment and tools on the production line may need to be adjusted for different sizes of bottles. Second, during the assembly of the gas valve, manual centering operation is still needed at present, which not only increases the production cost, but also is inefficient. Manual centering not only consumes time and effort, but is also easily affected by human factors, making it difficult to guarantee the assembly accuracy and consistency. CONTENT OF THE UTILITY MODEL

[0008] As a further scheme of the utility model: a clamping plate is fixedly connected to the clamping arm.

[0009] As a further scheme of the utility model: the bearing frame is fixedly connected with a vertical rod, the vertical rod is slidably connected with a cantilever beam, the cantilever beam is rotatably connected with a knob, and the knob is fixedly connected with a fixed frame at one end.

[0010] As a further scheme of the utility model: two clamping plates are arranged between the clamping plates.

[0011] As a further scheme of the utility model: the fixed frame is fixedly connected with a bottle valve, the clamping plates are arranged in an arc shape, and the centers of symmetry of the two clamping plates and the geometric center of the hexagonal hole arranged on the fixed frame are on the same vertical line.

[0012] Compared with the prior art, the utility model has the beneficial effects that:

[0013] 1. The utility model is provided with a clamping mechanism, and the clamping mechanism has the adjustable characteristic, which means that it can be flexibly adapted to composite gas bottles of various diameters. Through the adjusting mechanism, the effective clamping of composite gas bottles of various models can be easily realized, so that the needs of different application scenarios can be met.

[0014] 2. The clamping mechanism of the utility model is closely associated with the valve screwing mechanism.
