[0022] like Figure 2 and Figure 3 As shown, the base 1 of the focusing detection equipment has a first motor placement slot 11 inside, which provides installation space for the motor. A first step motor 12 is fixedly installed on the bottom wall of the first motor placement slot 11. The first step motor 12 provides power to the equipment. The output end of the first step motor 12 is fixedly connected to a first drive shaft 13, which can transmit the power output by the motor. Two first bevel gears 14 are fixedly sleeved on the outer wall of the first drive shaft 13, which also transmit the power output by the motor.

[0023] The inner wall of the first motor placement slot 11 is provided with a first bidirectional threaded rod 15 corresponding to the position of the two first bevel gears 14. The thread design of the first bidirectional threaded rod 15 can drive the equipment to move. The front ends of the two first bidirectional threaded rods 15 are fixedly connected to the second bevel gears 16. The two second bevel gears 16 are meshed with the two first bevel gears 14. The direction of force can be changed through the meshing between the second bevel gears 16 and the first bevel gears 14.

[0024] The two first bidirectional threaded rods 15 are both rotatably inserted into the inner wall of the transverse positioning slide groove 10 at one end away from the two second bevel gears 16 and are rotatably connected to the rear wall of the transverse positioning slide groove 10. The vertical end of the T-shaped slider 3 is threaded onto the outer wall of the two first bidirectional threaded rods 15.

[0025] like Figure 4 and Figure 5 As shown, the top of the L-shaped positioning connecting frame 4 is provided with a second motor placement slot 17. The second motor placement slot 17 can provide installation space for the motor. The bottom wall of the second motor placement slot 17 is fixedly installed with a second stepper motor 18. The second stepper motor 18 is used to provide power to the equipment. The output end of the second stepper motor 18 is fixedly connected to a second transmission shaft 19. The second transmission shaft 19 is used to transmit the power output by the second stepper motor 18.

[0026] A worm gear 20 is fixedly sleeved on the outer wall of the second drive shaft 19. The worm gear 20 is also used to transmit force. A second bidirectional threaded rod 21 is provided on the inner wall of the second motor placement slot 17. The left end of the second bidirectional threaded rod 21 is rotatably connected to the left wall of the second motor placement slot 17. A worm wheel 22 is fixedly sleeved on the outer wall of the second bidirectional threaded rod 21. The worm wheel 22 is meshed with the worm gear 20.

The positioning transmission block 24 is fixedly connected to the focusing microscope 5.

[0028] The working principle of this utility model is as follows: When using this device, the PIN needle is first placed on the base 1 of the focusing detection equipment, and the rebound force generated by the cooperation between the telescopic sleeve rod 7 and the spring 8 pushes the fixing plate 9 to clamp and fix the PIN needle mold. Then, the starting and stopping of the first stepper motor 12 and the second stepper motor 18 are controlled by the control device controller 2 to achieve precise positioning. Specifically, when the first stepper motor 12 starts, the output end of the first stepper motor 12 drives the first transmission shaft 13 to rotate synchronously. The first transmission shaft 13 drives the first bidirectional threaded rod 15 to rotate synchronously through the meshing between the first bevel gear 14 and the second bevel gear 16. The first bidirectional threaded rod 15 rotates through the interaction with the T-shaped slider 3. The threaded relationship between the two motors synchronously drives the microscope to slide on the inner wall of the transverse positioning groove 10. The T-shaped slider 3 drives the L-shaped positioning connecting frame 4 to slide, thereby moving the focusing microscope 5 to achieve transverse positioning. Then, the second stepper motor 18 is started, and the output end of the second stepper motor 18 synchronously drives the second transmission shaft 19 to rotate. The second transmission shaft 19 synchronously drives the second bidirectional threaded rod 21 to rotate through the meshing between the worm 20 and the worm wheel 22. Then, the threaded relationship between the second bidirectional threaded rod 21 and the positioning transmission block 24 synchronously drives the focusing microscope 5 to move. The vertical positioning is completed by moving the focusing microscope 5. The precise positioning is achieved by indirectly driving the focusing microscope 5 to move through the rotation of the two motors.
