[0025] For the embodiments, please refer to Figures 1-5 The present utility model provides a technical solution:

[0026] A computer graphics card plugging and unplugging test device includes a base 1. A limiting block 2 is installed at the center position of the top of the base 1. A bottom plate 3 is installed at one end of the top of the base 1. A support plate 4 is installed on the top of the bottom plate 3. A driving motor 5 is installed on the wider outer side surface of the support plate 4. A turntable 6 is installed on the outer side surface of the support plate 4 away from the driving motor 5. One end of the outer side surface of the turntable 6 is installed with a connecting rod 7. The end of the connecting rod 7 away from the turntable 6 is installed with a movable push rod 8. The end of the movable push rod 8 away from the connecting rod 7 is installed with a mounting plate 9.

A pressing plate 13 is installed at the bottom of the adjusting bolt 12. A computer graphics card 14 is installed at the top of the pressing plate 13 and located on the top of the first fixing plate 10;

[0027] At one end of the top of the base 1 away from the bottom plate 3, a support block 15 is installed. At the top of the support block 15, a rotating block 16 is installed. At both ends of the wider side surface of the outside of the support block 15, limiting grooves 1501 are symmetrically opened. Inside the limiting grooves 1501, bumps 17 are installed. On the outside side surfaces of the bumps 17, limiting holes 1701 are opened. On the outer side surfaces of the bumps 17 together, a socket 18 is installed. Inside the support block 15 and between the two limiting grooves 1501, a cavity 1502 is opened. On the narrower two side walls inside the cavity 1502, return springs 19 are symmetrically installed. At one end of the return spring 19, a triangular block 20 is installed. On the outer side surface of the triangular block 20 and inside the return spring 19, a limiting rod 21 is installed. Between the inner top and bottom of the cavity 1502, a threaded rod 22 is installed together. On the outer ring surface of the threaded rod 22, a trapezoidal block 23 is installed.

[0028] Specifically, referring to Figure 1 , one end of the connecting rod 7 is rotatably connected to one end of the movable push rod 8, and the outer ring surface of the movable push rod 8 is slidably connected to the inside of the limiting block 2, so as to ensure that when one end of the connecting rod 7 rotates along the outside of the turntable 6, it drives the movable push rod 8 to reciprocate on the limiting block 2. When the movable push rod 8 moves to the farthest point, it synchronously drives the socket on the computer graphics card 14 to be inserted into the slot of the socket 18, so as to drive the computer graphics card 14 to be repeatedly inserted and pulled out for testing.

[0029] Further, the output shaft of the drive motor 5 penetrates through the support plate 4 and is connected to the turntable 6, and one end of the outer side surface of the turntable 6 is rotatably connected to one end of the connecting rod 7, so as to ensure that the turntable 6 is driven by the drive motor 5 to rotate and drive one end of the connecting rod 7 to rotate along the outside of the turntable 6.

[0030] Further, the bottom end of the adjusting bolt 12 penetrates through the second fixing plate 11 and is rotatably connected to the top of the pressing plate 13, and the outer ring surface of the adjusting bolt 12 is threadedly connected to the inside of the second fixing plate 11, so as to ensure that by rotating the adjusting bolt 12, the pressing plate 13 is driven to descend to limit and fix computer graphics cards 14 of different sizes.

[0031] Further, the top end of the threaded rod 22 penetrates to the outside of the support block 15 and is connected to the rotating block 16, and the bottom end of the threaded rod 22 is rotatably connected to the inner bottom of the cavity 1502. The outer ring surface of the threaded rod 22 is threadedly connected to the inside of the trapezoidal block 23, so as to ensure that by driving the threaded rod 22 to rotate through the rotating block 16, the trapezoidal block 23 is synchronously driven to move on the outside of the threaded rod 22 and squeeze the two triangular blocks 20.

[0032] Specifically, referring to such as Figure 3 and Figure 4, one end of the limiting rod 21 away from the triangular block 20 penetrates through the inner wall of the return spring 19 and then penetrates through the inner wall of the cavity 1502 and extends into the limiting groove 1501. After the convex block 17 is inserted into the limiting groove 1501, the limiting rod 21 can be inserted into the limiting hole 1701, so as to ensure that the two triangular blocks 20 are squeezed relatively away by the trapezoidal block 23. When the triangular blocks 20 move, they simultaneously squeeze the return spring 19 and drive the limiting rod 21 to move and be inserted into the limiting hole 1701, thereby fixing the socket 18 on the support block 15, which is convenient for disassembly and replacement of sockets 18 of different sizes.

[0033] The working process of the present utility model: When using a computer graphics card plugging and unplugging test device designed by this solution to perform plugging and unplugging tests on a computer graphics card, first, rotate the adjusting bolt 12 to drive the pressing plate 13 to descend to limit and fix computer graphics cards 14 of different sizes. Drive the turntable 6 to rotate by the driving motor 5, and drive one end of the connecting rod 7 to rotate along the outside of the turntable 6. When one end of the connecting rod 7 rotates along the outside of the turntable 6, it drives the movable push rod 8 to reciprocate on the limiting block 2. When the movable push rod 8 moves to the farthest point, it simultaneously drives the socket on the computer graphics card 14 to be inserted into the slot of the socket 18, thereby driving the computer graphics card 14 to be repeatedly plugged and unplugged for testing. The number of rotations of the turntable 6 is connected to an external counting device to record the number of plugging and unplugging times. Rotate the rotating block 16 to drive the threaded rod 22 to rotate, and simultaneously drive the trapezoidal block 23 to move on the outside of the threaded rod 22 to squeeze the two triangular blocks 20. When the triangular blocks 20 move, they simultaneously squeeze the return spring 19 and drive the limiting rod 21 to move and be inserted into the limiting hole 1701, thereby fixing the socket 18 on the support block 15, which is convenient for disassembly and replacement of sockets 18 of different sizes, so as to facilitate the testing of computer graphics cards of different models and has a wider practicability.
