[0007] High-voltage electric field provided by battery excites cold cathode to emit electrons, and then X-ray is generated. Compared with using alternating current power supply, battery power supply can reduce the size of ray machine, improve portability, while possibly reducing energy consumption and simplifying power supply system. Make the ray machine can adapt to cable detection such as high-altitude operation.

[0008] The battery is built-in in the shell, which can effectively prevent the battery from being damaged by impact, extrusion and other damages in the external environment, thereby prolonging the service life of the battery and reducing the risk of equipment failure caused by battery failure.

[0011] A concave groove is provided on the surface of the outer shell, the base is fixed in the groove, and the handle is located in the groove and rotatably connected to the base.

[0012] In the prior art, the cold cathode ray machine only wraps the ray machine, and components such as batteries, handles, and antennas are all exposed in the air. When performing non-destructive testing on charged circuits, the X-ray machine needs to be mounted near the charged circuit and the position adjusted until the imaging plate can clearly image. Components such as the handle and battery set outside the device may touch other wires, causing an electrical accident and limiting the adjustable range of the X-ray machine.

[0013] Setting the handle assembly facilitates the carrying and transfer of the X-ray machine.
