[0015] In order to make the purpose, technical scheme and advantages of the embodiments of the utility model clearer, the technical scheme in the embodiments of the utility model will be clearly and completely described below in conjunction with the drawings in the embodiments of the utility model. Obviously, the described embodiments are part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without making creative work belong to the scope of protection of the utility model. Therefore, the following detailed description of the embodiments of the utility model provided in the drawings is not intended to limit the scope of the utility model for which protection is sought, but merely represents the selected embodiments of the utility model. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without making creative work belong to the scope of protection of the utility model.

[0016] like Figures 1 to 3 As shown, the angle adjustment device includes: a movable mounting plate 1, a fixed mounting plate 2, a support block 4, a left adjustment plate 7, a right adjustment plate 8, an adjustment block 6 and an adjustment screw 5. The angle adjustment device is suitable for adjusting the installation angle of the visual inspection camera lens.

[0017] Among them, two first rotating supports 11 are arranged on the movable mounting plate 1, and two second rotating supports 21 are arranged on the fixed mounting plate 2. The two second rotating supports 21 are respectively arranged on both sides of the first rotating support 11. The first rotating support 11 and the second rotating support 21 are connected through the first rotating shaft 3 so that the movable mounting plate 1 can rotate around the first rotating shaft 3 to adjust the angle. The middle part of the first rotating shaft 3 passes through the support block 4.

[0018] Further preferably, the movable mounting plate 1 and the fixed mounting plate 2 are arranged in a V shape, so that the included angle between the movable mounting plate 1 and the fixed mounting plate 2 ranges from 0° to 80°.

[0019] Next, one end of the left adjustment plate 7 is hinged to the third rotation support 71 , and the third rotation support 71 is locked to the fixed installation plate 2 , so that the left adjustment plate 7 can be rotated to adjust the angle.

[0020] One end of the right adjustment plate 8 is hinged to the fourth rotation support 81, and the fourth rotation support 81 is locked to the movable mounting plate 1, so that the right adjustment plate 8 can be rotated to adjust the angle.

[0021] Then, a second rotating shaft is penetrated in the adjusting block 6 , and two ends of the second rotating shaft are respectively connected to the other end of the left adjusting plate 7 and the other end of the right adjusting plate 8 .

[0022] Next, the adjusting screw 5 is passed through the adjusting block 6 and locked on the supporting block 4 .

[0023] Preferably, a locking nut 61 is provided on the adjusting screw 5, and the locking nut 61 is installed on the side of the adjusting block 6 away from the supporting block 4. After repeated tightening and disassembly, the locking force of the loosening nut does not decrease, and the original locking effect can be maintained, and the angle adjustment can be withstood for a long time without loosening.
