Then, when adjusting the angle, it is only necessary to press the connecting plate 38 through the mounting rod 26 to release the restriction of the limiting tooth block 41 and the limiting tooth groove 40, and then rotate the mounting rod 26 to adjust the angle of the thoracoscope. When the adjustment is completed, release the mounting rod 26 so that the limiting tooth groove 40 of the connecting plate 38 and the limiting tooth block 41 inside the cavity 36 can be limited by the reset spring 39 at one end of the rotating plate 37 to complete the angle adjustment and positioning. The positioning tooth block 41, the limiting tooth groove 40 and the reset spring 39 can adjust the angle of the thoracoscope quickly and conveniently. At the same time, by starting the motor 9, the motor 9 drives the driving gear 10 to rotate, and then drives the meshing driven gear 11 to rotate. With the rotation of the driven gear 11, the L-shaped connecting rod 12 will be driven to rotate. With the rotation of the L-shaped connecting rod 12, the supporting angle of the connecting disk 24 will be changed through the connecting arm 22, thereby increasing the diversity of the angle adjustment of the thoracoscope during operation, and facilitating the adjustment of any angle. The motor 2 13 and the motor 3 18 can respectively drive the L-shaped connecting rod 2 17 and the L-shaped connecting rod 3 21 to rotate, and the supporting angle of the connecting disk 24 can be changed through the connecting arm 22.
