[0021] As a further description of the above technical solution, the mobile phone screen fixing frame 7 includes two brackets 72 arranged in parallel left and right. Both brackets 72 are fixed to the front end of the mounting frame 2, and two gear shafts 9 are respectively rotatably connected to the front parts of the two brackets 72; A table board 71 is slidably installed at the top of the two brackets 72 in common. The table board 71 has a central window that penetrates the top and bottom of the table board 71, and a light-transmitting glass 73 is embedded in the central window. The top surface of the light-transmitting glass 73 is flush with the top surface of the table board 71; A number of sliding grooves 712 are respectively opened at the upper end of the table board 71, and a number of notches 713 are respectively opened at the front sides of the sliding grooves 712 on the table board 71; The sliding groove 712 is an inverted T-shaped groove; A sliding seat 74 is slidably arranged in the sliding groove 712, and the sliding seat 74 slides in the sliding groove 712 and forms an engaging structure with the sliding groove 712; The sliding seat 74 slides along the sliding groove 712 and forms an engaging structure with the sliding groove 712, and the sliding seat 74 will not detach from the table board 71 upwards during the sliding process; Bevel gear rods 77 are respectively rotatably arranged on both sides and the front end of the table board 71; Each bevel gear rod 77 is composed of a rod part and bevel gears fixed at both ends of the rod part, and the rod part is rotatably connected to the table board 71; A secondary driving bevel gear 78 is also fixedly sleeved on the rod part of the bevel gear rod 77 located at the front end of the table board 71, and the secondary driving bevel gear 78 is arranged in the notch 713; The rotation of the secondary driving bevel gear 78 drives the bevel gear rod 77 to rotate, so that the two bevel gear rods 77 rotate; On the inner sides of the two sliding seats 74, a clamping plate 75 is respectively fixed, and the bottom end of the clamping plate 75 abuts against the top end of the table plate 71; on the outer sides of the two sliding seats 74, a lead screw 741 is respectively fixed, and the two lead screws 741 have opposite helix directions. An internally threaded tube 742 is respectively fixed on the two lead screws 741. A transmission bevel gear 76 is respectively fixed on the outer side surfaces of the two internally threaded tubes 742. The transmission bevel gear 76 is sleeved on the lead screw 741 and is in clearance fit with the lead screw 741; the two transmission bevel gears 76 are respectively meshed with the two bevel gear rods 77; it should be noted that the two bevel gears forming the bevel gear rod 77 are distributed in the same direction, and the two lead screws 741 have opposite helix directions, so that when the bevel gear rod 77 rotates, the two bevel gear rods 77 rotate synchronously in the same direction, and the two lead screws 741 move towards or away from each other. Therefore, the two clamping plates 75 can be made to approach or move away from each other by rotating the sub-driving bevel gear 78; When fixing the mobile phone screen 500 to be measured through the mobile phone screen fixing frame 7 to facilitate the detection of the mobile phone screen 500 to be measured, the mobile phone screen 500 to be measured is placed at the center of the top end of the light-transmitting glass 73, and the back surface of the mobile phone screen 500 to be measured abuts against the top end of the light-transmitting glass 73. Then, the sub-driving bevel gear 78 is rotated to one side to drive the two bevel gear rods 77 to rotate, so that the two lead screws 741 approach each other and push the two clamping plates 75 to clamp the left and right sides of the mobile phone screen 500 to be measured.

[0022] It should be noted that to facilitate the rotation of the internally threaded tube 742, the rotation of the internally threaded tube 742 is converted into the movement of the lead screw 741 along the chute 712; the internally threaded tube 742 is rotatably provided with a shaft seat 743, and the shaft seat 743 is fixed to the bottom surface of the chute 712; It should be noted that to facilitate driving the sub-driving bevel gear 78 to rotate, a driving handle 79 is fixed at the front end of the table plate 71. The output end of the driving handle 79 is meshed with the sub-driving bevel gear 78. The driving handle 79 is used to drive the bevel gear rod 77 to rotate. Rotating the driving handle 79 makes the driving shaft rotate, which can drive the sub-driving bevel gear 78 to rotate, and further realize the rotation of the bevel gear rod 77.

[0023] In the mobile phone screen fixing frame 7, through the transmission of multiple bevel gears, the self-locking force brought by the two meshing bevel gears can be utilized to form a self-locking effect after the two clamping plates 75 clamp and fix the mobile phone screen 500 to be measured, realizing automatic self-locking and ensuring the fixing effect of the mobile phone screen 500 to be measured.

[0024] When it is necessary to take out the mobile phone screen 500 to be measured, rotate the driving handle 79 again in the direction opposite to the rotation direction of the driving handle 79 when fixing the mobile phone screen 500 to be measured, so that the two clamping plates 75 are separated from the mobile phone screen 500 to be measured, and the mobile phone screen 500 to be measured can be taken out.

[0025] As a further description of the above technical solution, the push-pull frame 10 includes a push-pull rod 101 and two support rods 104. The lifting frame 11 is fixed to the lower end of the push-pull rod 101. A square tube 102 is fixed to each of the left and right ends of the push-pull rod 101. The two support rods 104 are respectively inserted into the square tubes 102 from the rear openings of the two square tubes 102. The two support rods 104 are both fixedly inserted into the mounting frame 2. A lower rack 103 is fixed to the top of each of the two square tubes 102. The upper parts of the two lower racks 103 are respectively engaged with the two gear shafts 9. When the push-pull rod 101 moves towards the gear shaft 9, the two lower racks 103 respectively drive the two gear shafts 9 to rotate, so that the two upper racks 8 drive the table board 71 to move towards the front opening of the equipment cabinet 100. On the contrary, when the push-pull rod 101 moves towards the front opening of the equipment cabinet 100, the table board 71 moves back to the upper end of the bracket 72.

[0026] It should be noted that, to facilitate the control of the sliding of the table board 71 on the two brackets 72, an inverted T-shaped guide groove 721 is provided on each of the two brackets 72. The narrow part of the guide groove 721 penetrates the bracket 72 upwards. A slider 711 is fixed to the bottom end of the table board 71. The two sliders 711 are respectively slidably arranged in the two guide grooves 721. When the table board 71 is directly above the bracket 72, the two sliders 711 are both in contact with the mounting frame 2. When the table board 71 moves to the extreme position towards the front opening of the equipment cabinet 100, the sliders 711 are in contact with the front inner wall of the guide groove 721. During the movement and stillness of the table board 71, the gear shaft 9 remains engaged with the upper rack 8 and the lower rack 103.

[0027] As a further description of the above technical solution, the lifting frame 11 includes two vertical rods 111 arranged vertically.

The two support knobs 1111 can be respectively inserted into the two adjusting blocks 114. When the front reflector 300 moves up to the limit position along the guide post 13, the two support knobs 1111 are inserted into the two adjusting blocks 114 to limit the height position of the front reflector 300. At the same time, the connected support knob 1111 and adjusting block 114 cooperate with the inclined guide post 13 to limit the up-and-down position and front-and-back position of the front reflector 300, and the front reflector 300 is limited directly in front of the rear reflector 200. In this state, the push-pull rod 101 cannot move towards the bracket 72 any more, and the table board 71 cannot move towards the front opening of the equipment cabinet 100 any more, so that the table board 71 and the screen 500 of the mobile phone to be measured are limited directly above the rear reflector 200; After the screen 500 of the mobile phone to be measured is limited directly above the rear reflector 200, the pin 6 is connected to the screen 500 of the mobile phone to be measured through the electric push rod 4.

[0028] To provide support for the front-and-back movement of the vertical rod 111 and maintain the stability of the vertical rod 111 during the front-and-back movement, a hollow tube 112 is respectively fixed to the bottom end of each vertical rod 111. A support frame 113 is jointly embedded at the rear ends of the two hollow tubes 112. The support frame 113 is slidably matched with the hollow tube 112. The support frame 113 is fixed to the front end of the mounting frame 2; A guide seat 14 is slidably sleeved on each hollow tube 112. The guide seat 14 is fixed to the top end of the bottom table 1.

[0029] The specific process of realizing the movement of the table board 71 between the bracket 72 and the front opening of the equipment cabinet 100, the movement of the front reflector 300 along the guide post 13, and the installation of the screen 500 of the mobile phone to be measured through the push-pull frame 10 and the lifting frame 11 is as follows: First, according to the foregoing, in the initial state, the push-pull rod 101 and the bracket 72 are in the state of the minimum distance, the table board 71 moves forward to the state of the minimum distance from the front opening of the equipment cabinet 100, the slider 711 abuts against the front groove wall surface of the guide groove 721, the front reflector 300 is below the rear reflector 200, the front mounting seat 115 is at the lowest position, and the support knob 1111 is disengaged from the adjusting block 114; Place the mobile phone screen 500 to be measured on the light-transmitting glass 73, and rotate the driving handle 79 to make the two clamping plates 75 approach and clamp the mobile phone screen 500 to be measured. Push the driving handle 79 towards the bracket 72, so that the slider 711 slides backward along the guide groove 721 until it abuts against the mounting frame 2, causing the table plate 71 to slide backward and reach directly above the bracket 72. During this process, the upper rack 8 slides backward with the table plate 71 and drives the gear shaft 9 to rotate, driving the lower rack 103 to move forward. The square tube 102 slides forward along the support rod 104, driving the push-pull rod 101 to move forward, causing the vertical rod 111 to move forward, driving the hollow tube 112 to move forward along the support frame 113. During the forward movement of the vertical rod 111, the front mounting seat 115 and the front reflector 300 are driven to move forward through the adjusting block 114 and the vertical guide groove 1112. Affected by the inclined guide posts 13 and the guide tubes 12, the front reflector 300 moves forward and upward during the forward movement, causing the adjusting block 114 and the front mounting seat 115 to move upward along the vertical guide groove 1112. When the slider 711 abuts against the mounting frame 2, the front reflector 300 moves to directly in front of the rear reflector 200, the adjusting block 114 is aligned with the support knob 1111, the table plate 71 slides to directly above the bracket 72, and the mobile phone screen 500 to be measured moves to directly below the pin 6. Then, rotate the support knob 1111 to insert the support knob 1111 into the adjusting block 114, and the electric push rod 4 pushes the pin 6 downward to make the pin 6 abut against the mobile phone screen 500 to be measured.
