The location of the launching device 500 in space can meet the needs of different clinical conditions and at the same time adapt to installation spaces of different sizes.

In some embodiments of the present invention, referring to FIGS. 1 and 5 , in order to rotate the X-ray emitting device 500 in a vertical plane to quickly adjust its position in space, while avoiding the rotation of the X-ray emitting device 500 During the action, the structural stability of the telescopic cylinder 400 is affected. The bottom end of the telescopic cylinder 400 is rotatably installed with a mounting seat 600 . The mounting seat 600 is provided with a horizontal rotating shaft 700 . The axis is perpendicular to the horizontal rotation axis 700. It can be understood that, in combination with the X-ray emission device 500 being able to rotate around the axis of the telescopic cylinder 400, the X-ray emission device 500 can be freely rotated in the horizontal plane and in the vertical plane, so as to quickly adjust the X-ray emission device.
