[0004] When the above-mentioned clamping device is in use, the distance between the two fixing devices can be adjusted by turning two hand wheels so that the pump body can be fixed. However, the two fixing devices are driven by staff using hand wheels. In the process of manually driving the two fixing devices close to each other, due to the different sizes of different pump bodies, the two fixing devices are driven close to each other to clamp the pump body. The size of the clamping effect of the two fixing devices on the pump body depends entirely on the experience of the staff. When the clamping effect is large, it will cause damage to the pump body.

[0005] To this end, we propose a refueling pump body processing device with a limit locking function to solve the problem that the pump body is easily damaged during the clamping process of the pump body in the prior art because there is no corresponding limit component to limit the protection of the pump body.
