Two groups of slide grooves 15 are symmetrically provided on the strip rod 14. Slide blocks 16 are slidably connected in the two groups of slide grooves 15. Springs 1501 are provided in the two groups of slide grooves 15. One end of the spring 1501 is fixedly connected to the slide block 16, and the other end is fixedly connected to one end of the slide groove 15. The first transmission wheel 18 is rotatably connected to the side of the two groups of slide blocks 16 close to the output rod 8. The second transmission wheel 19 is rotatably connected to the side of the adjusting rod 11 close to the output rod 8. The same group of transmission belts 20 are sleeved on the two groups of first transmission wheels 18 and the second transmission wheels 19. The two groups of slide blocks 16 are rotatably connected to the side away from the first transmission wheel 18. The two groups of transmission rods 17 are respectively fixedly connected to the two groups of first transmission wheels 18. The other ends of the two groups of transmission rods 17 are connected to a dust box 23 for protecting the pressure head 13. The dustproof box 23 includes a first box body and a second box body overlapped with each other, and the tops of the first box body and the second box body are respectively provided with semicircular holes, and the two groups of semicircular holes are symmetrically arranged, and the hole walls of the semicircular holes are fitted to the outer periphery of the pressure head 13, and the first box body and the second box body are respectively connected with two groups of transmission rods 17, and the first box body and the second box body are respectively fixedly connected with connecting rods 22 on one side close to the strip rod 14, and the top of the strip rod 14 is symmetrically provided with two groups of limiting grooves 1401, and the other ends of the two groups of connecting rods 22 are respectively slidably matched with the two groups of limiting grooves 1401; A fixed rod 9 has one end fixedly connected to the outer shell of the driving end of the electric drive rod 5, and the other end fixedly connected to a limit ring 10, on which a ring groove 1001 is provided, and the center of the circle of the limit ring 10 and the ring groove 1001 coincides with the axis of the output rod 8, and a sliding rod 21 is fixedly connected to the center of one side of the strip rod 14 near the limit ring 10, and the other end of the sliding rod 21 is slidably matched with the ring groove 1001.

[0020] In this embodiment, the operator places the fingerprint module in the base groove 201. When the fingerprint module needs to be tested, the electric drive rod 5 is started to drive the mounting frame 6 and the adjustment rod 11 to move downward synchronously. The adjustment rod 11 drives the controller 12 and the pressure head 13 to move downward so that the pressure head 13 presses the recognition area of ​​the fingerprint module to test the fingerprint module. Usually, when a user's finger actually presses the fingerprint module, it is difficult to ensure that the center of the fingerprint module recognition area is pressed every time. The finger will often deviate from the center of the fingerprint module, and the angle and direction of the finger pressing the fingerprint module each time are not fixed. In order to simulate the situation when the user's finger actually presses the fingerprint module for testing, the output rod 8 is driven to rotate by the first motor 7, and the output rod 8 drives the adjustment rod 11 to rotate around the axis of the output rod 8. The adjustment rod 11 drives the controller 12 and the pressure head 13 to revolve around the axis of the output rod 8. After the pressure head 13 revolves, the pressure head 13 will deflect and deviate from the center of the fingerprint module according to the deflection angle generated by the pressure head 13. At this time, the electric drive rod 5 is controlled to drive the pressure head 13 to press down the fingerprint module, which can simulate the user's finger pressing the fingerprint module at different angles. In addition, by driving the rotating ring 3 to rotate, the pressure head 13 can be driven to revolve around the axis of the base groove 201, thereby simulating the user's finger pressing from different directions, thereby improving the test accuracy of the fingerprint module. When the adjusting rod 11 revolves around the axis of the output rod 8, the adjusting rod 11 will drive the strip rod 14 to revolve around the axis of the output rod 8 synchronously, and the sliding rod 21 will slide in the limiting ring 10 and the annular groove 1001; When placing or taking the fingerprint module, the operator will control the electric drive rod 5 to drive the controller 12 and the pressure head 13 to move up and reset. The first box body and the second box body will fit on both sides of the end of the pressure head 13 to prevent dust from being adsorbed on the pressure head 13 and affecting the test accuracy. At this time, the spring 1501 is in a stretched energy storage state. When the electric drive rod 5 drives the adjustment rod 11, the controller 12 and the pressure head 13 to move downward as a whole, the annular groove 1001 limits the strip rod 14 through the sliding rod 21. Therefore, when the adjustment rod 11 moves downward, the height of the strip rod 14 remains unchanged. During the process, the strip rod 14 slides along the adjustment rod 11, and the second transmission wheel 19 moves down and gradually approaches the two sets of first transmission wheels 18. At this time, the energy storage release of the spring 1501 will drive the two sets of first transmission wheels 18 to move away from each other, and then drive the two sets of sliders 16 and the two sets of transmission rods 17 to move away from each other. The two sets of transmission rods 17 then drive the first box body and the second box body to move away from each other. As the controller 12 and the pressure head 13 continue to move down, the first box body and the second box body will gradually move to both sides of the controller 12, so that the pressure head 13 is completely exposed to complete the test of the fingerprint module; When the electric drive rod 5 drives the pressure head 13 and the controller 12 to move up and reset, the second transmission wheel 19 will gradually move up. Driven by the transmission belt 20, the two groups of first transmission wheels 18 will approach each other and stretch the spring 1501 to generate energy storage. After the pressure head 13 and the controller 12 are completely moved up and reset, the first box body and the second box body are fitted together on both sides of the end of the pressure head 13.

The adjusting rod 11 drives the controller 12 and the pressure head 13 to revolve about the axis of the output rod 8. After the pressure head 13 revolves, the pressure head 13 will be deflected and will shift from the center of the fingerprint module according to the deflection angle generated by the pressure head 13.
