[0007] The reciprocating assembly includes two sets of fixed plates, which are respectively installed at both ends of the top of the support base. A push plate passes through the upper end of the fixed plate. The top and bottom of the push plate are connected with teeth. The ends of the teeth away from the push plate are respectively meshed with a first incomplete gear and a second incomplete gear. A transmission component is provided between the first incomplete gear and the second incomplete gear. A support plate is connected between the first incomplete gear and the second incomplete gear and the fixed plate. A drive motor for driving the first incomplete gear to rotate is installed on one side of the upper support plate.
[0008] By adopting the above technical solution, the lens holder is fixed by the lens holder fixing assembly, and the moving plate is opened. The moving plate extends and drives the frame to move upward. After moving to the appropriate position, the temple is fixed by the temple fixing assembly. Then, the drive motor is turned on. When the drive motor is working, it drives the first incomplete gear to rotate. Since the first and second incomplete gears are both meshed with the teeth on the push plate, as the drive motor rotates continuously, it can drive the two sets of temple fixing assemblies to move back and forth continuously, applying force to the temples. This allows for fatigue testing of the frame. The use of the drive motor shortens the testing time and makes it convenient to use.
[0009] Optionally, support columns are connected to both ends of the bottom of the bearing seat.
[0010] By adopting the above technical solution, the entire device is supported by two sets of support columns.
[0011] Optionally, the transmission component includes a driven pulley connected to the front end of a second incomplete gear, and a driving pulley connected to the front end of the first incomplete gear. A connecting belt is provided between the driven pulley and the driving pulley for external transmission.
[0012] By adopting the above technical solution, the rotation of the first incomplete gear drives the rotation of the driving pulley, and the rotation of the driving pulley drives the rotation of the driven pulley through the connecting belt, which in turn drives the rotation of the second incomplete gear.
[0013] Optionally, a guide assembly is provided between the movable plate and the support seat. The guide assembly includes two sets of guide rods, which are respectively installed at both ends of the bottom of the movable plate. The bottom of both sets of guide rods extends out of the support seat, and the surface of the support seat is provided with guide holes that match the guide rods.
[0014] By adopting the above technical solution, when the moving plate is raised or lowered, it can drive the guide rod to slide inside the guide hole, thereby making the moving plate more stable during the movement.

[0016] By adopting the above technical solution, the first handle is rotated, which drives the first screw to rotate. The rotation of the first screw drives the pressure blocks to rotate and move closer to each other until the two sets of pressure blocks fix the temple.
[0017] Optionally, a first rubber pad is connected to the end of the pressure block that is away from the first screw.
[0018] By adopting the above technical solution, the friction between the pressure block and the temple is increased by setting the first rubber pad, making the temple clamped more firmly.
[0019] Optionally, the lens holder fixing assembly includes a vertical plate, which is installed on the top of the movable plate. A fixing clamp is connected to the lower end of one side of the vertical plate, and an mounting plate is installed on the upper end of one side of the vertical plate.

[0020] By adopting the above technical solution, the bottom of the lens holder is placed on top of the fixed clamp. The second handle is rotated, which drives the second screw to rotate. Under the limiting action of the slide rod, the second screw rotates and drives the movable clamp to move downward until the movable clamp presses on the top of the lens holder, thereby fixing the lens holder.
[0021] Optionally, a second rubber pad is connected to both the bottom of the movable clamping plate and the top of the fixed clamping plate.
[0022] By adopting the above technical solution, the friction between the movable clamp and the fixed clamp and the lens holder is increased by setting the second rubber pad, thereby making the lens holder clamped more securely.

Detailed Implementation
[0031] The following is in conjunction with the appendix Figure 1-3 The present invention will be described in further detail below.
[0032] Please refer to the attached diagram in the instruction manual. Figure 1 One embodiment of this utility model provides a fatigue testing device for sunglasses frames, including a support base 2, an electric push rod 4 fixedly installed in the middle of the support base 2, and support columns 3 fixedly connected to both ends of the bottom of the support base 2. The entire device is supported by two sets of support columns 3.
[0033] Please refer to the attached diagram in the instruction manual. Figure 1A movable plate 7 is mounted on the top of the electric push rod 4. A guide assembly 5 is provided between the movable plate 7 and the support seat 2. The guide assembly 5 includes two sets of guide rods 501, which are respectively vertically installed at both ends of the bottom of the movable plate 7. The bottom of both sets of guide rods 501 extends out of the support seat 2. The surface of the support seat 2 is provided with guide holes 502 that match the guide rods 501. When the movable plate 7 is raised or lowered, it can drive the guide rods 501 to slide inside the guide holes 502, thereby making the movable plate 7 more stable during movement.
[0034] Please refer to the attached diagram in the instruction manual. Figure 1 and Figure 3 The top of the movable plate 7 is provided with a mirror holder fixing assembly 8, which includes a vertical plate 805. The vertical plate 805 is fixedly installed on the top of the movable plate 7. A fixing clamp 807 is fixedly connected to the lower end of one side of the vertical plate 805. An mounting plate 803 is fixedly installed on the upper end of one side of the vertical plate 805. A second screw 802 is screwed to the middle of the mounting plate 803. A second handle 801 is installed on the top of the second screw 802. A movable clamp 806 is installed at the bottom of the second screw 802. Both ends of the top of the movable clamp 806 are connected to slide rods 804. The surface of the mounting plate 803 is provided with sliding holes that match the slide rods 804. Place the bottom of the lens holder on top of the fixed clamp 807, and rotate the second handle 801. The rotation of the second handle 801 drives the second screw 802 to rotate. Under the limiting action of the slide rod 804, the rotation of the second screw 802 drives the movable clamp 806 to move downwards until the movable clamp 806 presses against the top of the lens holder, thus fixing the lens holder in place. A second rubber pad 808 is connected to the bottom of the movable clamp 806 and the top of the fixed clamp 807. The second rubber pad 808 increases the friction between the movable clamp 806 and the fixed clamp 807 and the lens holder, thus making the lens holder clamped more securely.
[0035] Please refer to the attached diagram in the instruction manual. Figure 1 and Figure 2Both ends of the top of the support 2 are provided with reciprocating components 1. Each set of reciprocating components 1 has a temple fixing component 6 on the side near the center of the support 2. The temple fixing component 6 includes a frame 603. The side of the frame 603 away from the center of the support 2 is connected to the side of the push plate 106 near the center of the support 2. Circular holes 606 are provided at the top and bottom of the frame 603. First screws 602 are screwed to both the front and rear ends of the frame 603. First handles 601 are installed on the side of each set of first screws 602 away from the center of the frame 603. Pressure blocks 604 are installed on the side of each set of first screws 602 near the center of the frame 603. Rotating the first handle 601 causes the first screws 602 to rotate, which in turn causes the pressure blocks 604 to rotate and move closer together until the two pressure blocks 604 fix the temple. A first rubber pad 605 is connected to the end of the pressure block 604 away from the first screw 602. The first rubber pad 605 increases the friction between the pressure block 604 and the temple, making the temple more securely clamped.
[0036] Please refer to the attached diagram in the instruction manual. Figure 1 The reciprocating assembly 1 includes two sets of fixing plates 101, which are respectively vertically installed at both ends of the top of the bearing seat 2. A push plate 106 passes through the upper end of the fixing plate 101. The top and bottom of the push plate 106 are connected with teeth 105. The teeth 105 are respectively meshed with a first incomplete gear 103 and a second incomplete gear 108 at the ends away from the push plate 106. A transmission component 107 is provided between the first incomplete gear 103 and the second incomplete gear 108. The transmission component 107 includes a driven pulley 1071, which is connected to the front end of the second incomplete gear 108. The front end of the first incomplete gear 103 is connected to a driving pulley 1073. A connecting belt 1072 is provided for the external transmission of the driven pulley 1071 and the driving pulley 1073. The rotation of the first incomplete gear 103 drives the drive pulley 1073 to rotate. The rotation of the drive pulley 1073 drives the driven pulley 1071 to rotate via the connecting belt 1072, which in turn drives the second incomplete gear 108 to rotate. A support plate 102 connects the first incomplete gear 103 and the second incomplete gear 108 to the fixed plate 101. A drive motor 104 for driving the first incomplete gear 103 to rotate is installed on one side of the upper support plate 102.
[0037] Working principle: When in use, place the middle of the lens holder in the middle of the frame on the top of the fixed clamp 807. Then, the operator turns the second handle 801. The rotation of the second handle 801 drives the second screw 802 to rotate. Under the limiting action of the slide rod 804, the rotation of the second screw 802 drives the movable clamp 806 to move downward until the movable clamp 806 and the fixed clamp 807 fix the middle position of the frame.
[0038] Then, the electric push rod 4 is extended, which drives the moving plate 7 to move upward. The moving plate 7 moves upward, which drives the frame to move upward until the temple passes through the round hole 606 and extends out of the frame 603. At this time, the operator turns the first handle 601. The first handle 601 turns, which drives the first screw 602 to turn. The first screw 602 turns, which drives the pressure block 604 to turn and move until the two sets of pressure blocks 604 fix the temple.
[0039] Then the operator turns on the drive motor 104. When the drive motor 104 is working, it drives the first incomplete gear 103 to rotate. Since both the first incomplete gear 103 and the second incomplete gear 108 are engaged with the teeth 105 on the push plate 106, when the first incomplete gear 103 is engaged with the teeth 105, the rotation of the first incomplete gear 103 drives the push plate 106 to move outward away from the lens holder fixing assembly 8, thereby driving the two sets of temple fixing assemblies 6 to move away. The rotation of the first incomplete gear 103 drives the second incomplete gear 108 to rotate through the transmission component 107. When the second incomplete gear 108 is engaged with the teeth 105, the rotation of the second incomplete gear 108 drives the push plate 106 to move towards the lens holder fixing assembly 8. As the drive motor 104 rotates continuously, it can drive the two sets of temple fixing assemblies 6 to always reciprocate left and right, applying force to the temples, thereby enabling fatigue testing of the frame. The use of the drive motor 104 shortens the testing time and is convenient to use.
[0040] The above are all preferred embodiments of this utility model, and are not intended to limit the scope of protection of this utility model. Therefore, all equivalent changes made to the structure, shape and principle of this utility model should be covered within the scope of protection of this utility model.
