[0034] Alternatively, a triangular structure is provided with a wedge 44 (the angle of which cannot be adjusted), so that one side of the control box 42 is prevented from being movably connected to the support platform, and the wedge 44 is padded on the bottom surface of the control box 42 to adjust the tilt angle of the camera.

[0035] Further, such as Figure 4 As shown, the control box 42 is fixed, a triangular structure wedge 44 is fixed on the top surface of the control box 42, a support plate 43 is fixed on the wedge surface of the wedge 44, one end of the telescopic rod 41 passes through the support plate 43, the wedge 44 and the control box 42 in sequence and is connected to the first push rod 50. Preferably, the force is transmitted through the force transmission plate to drive the telescopic rod 41 to move in the vertical direction. The other end of the four telescopic rods 41 is a free end for clamping the camera 60, or, Figure 6 As shown, the wedge block 44 is not used, the control box 42 is fixedly and flatly placed on the supporting platform 100, one end of the support plate 43 is rotatably mounted on the control box 42, and the other end is a free end, and the second push rod 51 passes through the control box 42 in the vertical direction and is fixedly connected to the support plate 43, and the second push rod 51 moves in the vertical direction to adjust the inclination angle of the support plate 43.

[0036] During the test, the controller adjusts the distance or size of the scene image on the first display screen 3 to complete the test of the camera. Figure 7 As shown, when it is necessary to touch the switch or adjustment button on the camera 60, the edge position of the support plate 43 is a thin cylinder 45, the air source of the thin cylinder 45 adopts the air source external to the cylinder, and the thin cylinder 45 has its own push rod to touch the switch or adjustment button on the camera 60 to make contact.

[0037] The telescopic rods 41 are arranged in an L-shaped cross section, and four telescopic rods 41 are used to clamp the camera. With the up and down movement of the telescopic rods 41, the tilted arrangement can adapt to the clamping of cameras of different sizes.

[0038] As a specific implementation method provided in this case, a thin cylinder 45 is installed on the side of the control box 42, and the thin cylinder 45 is connected to the air source in the support frame 1.
