[0011] The bottom end of the movable rod is provided with a ball which contacts the arc plate.

[0012] As a further description of the above technical solution:

[0013] The connection block is slidably connected to the surface of the transverse plate.

[0014] As a further description of the above technical solution:

[0015] The arc-shaped plates on both sides are arranged in opposite directions.

[0016] In summary, due to the adoption of the above technical solution, the beneficial effects of the utility model are:

[0017] In the utility model, by providing an auxiliary component, when the screw is rotated, the moving block can drive the fixed plate, the camera device and the moving rod to move. When the moving rod moves on the arc plate, the fixed plate can be rotated back and forth on the movable axis through the connecting strip, which can drive the camera device to move, making it convenient for the camera device to test the shooting when it is shaking.

[0024] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments of the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0025] Reference Figure 1-Figure 3 , a dark box testing device, comprising a box body 1, an adjustable light is arranged on one side of the inner wall of the box body 1, and a photographic object is arranged on the other side of the inner wall of the box body 1, and an auxiliary component is arranged inside the box body 1; the interior of the auxiliary component comprises a horizontal plate 2 arranged inside the box body 1, and a motor 3 is arranged on one side of the horizontal plate 2, a screw rod 4 is arranged on the surface of the horizontal plate 2, and a connecting block 5 is threadedly connected to the surface of the screw rod 4, a concave plate 6 is connected to the top of the connecting block 5, and a movable shaft 7 is arranged on the inner wall of the concave plate 6, a connecting strip 8 is connected to the surface of the movable shaft 7, and a fixing plate 9 is connected to the top of the connecting strip 8, a camera device mounting seat 10 is slidably connected to the top of the fixing plate 9, and a cylinder 11 is arranged on one side of the camera device mounting seat 10; arc plates 12 are arranged on both sides above the screw rod 4; moving rods 13 are connected to both sides of the bottom end of the fixing plate 9. When in use, the adjustable light is first adjusted. To the specified brightness, and then through the operation of the motor 3, the screw 4 can be rotated, so that the connecting block 5 on its surface drives the fixed plate 9 and the camera equipment to move. When the fixed plate 9 moves, it can drive the moving rods 13 on both sides of its bottom end to move on the surface of the arc plate 12 through the ball bearings. By setting it on the arc plate 12, the moving rods 13 can be squeezed, so that the fixed plate 9 at the top of the moving rod 13 can drive the camera equipment to move back and forth through the movable shaft 7, so that the camera equipment can shoot while moving back and forth, which is convenient for testing the shooting of the camera equipment in this case. The surface of the box body 1 is hinged with a cover body (not shown), which is convenient for shielding the box body 1 to facilitate testing the camera equipment. The cylinder 11 is convenient for pushing the mounting seat 10 and the camera equipment on the mounting seat 10 to move, so as to adjust its position during testing.

[0026] Furthermore, a ball bearing in contact with the arc-shaped plate 12 is provided at the bottom end of the moving rod 13 , and the ball bearing facilitates the moving rod 13 to move on the surface of the arc-shaped plate 12 .

[0027] Furthermore, the connection block 5 is slidably connected to the surface of the horizontal plate 2, so that when the screw rod 4 rotates, the connection block 5 with threaded connection on its surface can mobilize the fixed plate 9 and the camera equipment to move in a limited position.

[0028] Furthermore, the arc plates 12 on both sides are arranged in opposite directions, so that when the moving rod 13 moves to the peak of the arc plate 12 on one side, the moving rod 13 on the other side moves to the depression of the arc plate 12 on the other side, so that the fixed plate 9 on the moving rod 13 can be moved through the movable shaft 7.
