[0023] Please see Figure 1 , Figure 2 , Figure 3 , Figure 4 There are two positioning rods 6, which are symmetrically distributed on the infrared detector 50. The positioning rods 6 can be used to position the infrared detector 50. The handle 9 is in contact with the horizontal part of the moving frame 5. The handle 9 is made of rubber. The handle 9 makes it easy to pull the insertion rod 8 to move. The rubber material has a good skin feel. A spring 10 is set on the outside of the insertion rod 8. One end of the spring 10 is fixedly connected to the handle 9, and the other end of the spring 10 is welded to the fixing ear 7. The handle 9 can be connected and used through the spring 10.

[0024] Please see Figure 1 , Figure 2 , Figure 3 The support frame 1 is equipped with a placement mechanism 11, which includes a support shaft 110. The support shaft 110 is mounted on the inner wall of the support frame 1 via bearings. A support platform 111 is fixedly connected to the upper end of the support shaft 110. The support platform 111 is rotatably connected to the inner bottom of the support frame 1. A pulley 114 is fixedly sleeved on the outer side of the support shaft 110. A motor 115 is fixedly installed on the inner bottom of the support frame 1 and to the right of the support platform 111. The output shaft of the motor 115 is rotatably connected to the support frame 1. A pulley 116 is fixedly sleeved on the outer side of the output shaft of the motor 115. A V-belt 117 is provided on the surface of the pulley 116 and the pulley 114. A cylinder 118 is fixedly installed on the front of the support frame 1.

[0025] Please see Figure 1 , Figure 2 , Figure 3The support platform 111 has an annular groove 112 on its side. The bottom inner side of the support frame 1 is fixedly connected to a limiting ball 113. The limiting ball 113 contacts the annular groove 112.

[0027] The specific implementation process of this utility model is as follows: In use, by pulling the handle 9 to move away from the moving frame 5, the insertion rod 8 is moved, causing the insertion rod 8 to slide along the inner wall of the fixed ear 7, thereby causing the spring 10 to deform, and then pushing the infrared detector 50 to contact the moving frame 5, so that the positioning rod 6 passes through the horizontal part of the moving frame 5. Under the action of the positioning rod 6, the infrared detector 50 can be quickly positioned and used. The handle 9 can be released to allow the spring 10 to return to its deformation, so that the insertion rod 8 can be pulled through the positioning rod 6, and the positioning rod 6 is inserted and limited, so that the positioning rod 6 drives the infrared detector 50 to be stable. Under the action of the infrared detector 50, the lens can be tested and used. When the output shaft of the motor 3 drives the screw 4 to rotate, under the threaded connection, the moving frame 5 can be driven to move the infrared detector 50, thereby improving the subsequent testing efficiency.

[0028] The support platform 111 allows for the placement and support of the lens. When the output shaft of the second motor 115 rotates, it drives the second pulley 116 to rotate. Under the transmission of the V-belt 117, the pulley 114 rotates, which in turn drives the support shaft 110 to rotate, ultimately causing the support platform 111 to rotate. This allows the lens to rotate, adjusting its test position and improving testing efficiency. When the support platform 111 rotates, the limiting ball 113 slides along the inner wall of the annular groove 112 to ensure the rotational stability of the support platform 111. Driven by the cylinder 118, the slider 119 moves the tension wheel 120, which tensions the V-belt 117 to ensure good transmission performance.
