Inside the housing 14, a sliding block 19 is slidably connected. Inside the housing 14, a one-way oil inlet pipe 20 is provided. Inside the housing 14, a one-way oil outlet pipe 4

[0034] Specifically, the mounting block 12 is used to stably install other components. The lubricating oil tank 13 is used to store lubricating oil. The housing 14 is used to stably install other components. The motor 15 is used to provide power to drive the rotation of the rotating shaft 16. The rotating shaft 16 is used to drive the rotation of the cam 17. The cam 17 is used to intermittently push the sliding block 19. The spring 18 is used to provide an elastic force. The sliding block 19 is used to squeeze out and suck in lubricating oil. Inside the one-way oil inlet pipe 20, a one-way oil valve is provided and can only allow oil to enter. Inside the one-way oil outlet pipe 4, a one-way oil valve is provided and can only allow oil to exit.

[0035] Refer to Figures 1-4 , the outer circumference of the bolt 3 is threadedly connected inside the cross beam 1. One end of the spring 18 is fixedly connected to the inner wall of the housing 14, and the other end of the spring 18 is fixedly connected to the sliding block 19. There is a contact between the cam 17 and the sliding block 19. The outer circumference of the rotating shaft 16 is rotatably connected inside the housing 14.

By adjusting the assembly positions of the cross beam 1 and the pull rod 2, the detection requirements for samples of different sizes and models can be met. The motor 15 is started, and the motor 15 drives the rotating shaft 16 to rotate inside the housing 14. The rotation of the rotating shaft 16 drives the cam 17. The cam 17 abuts against the sliding block 19 and intermittently pushes the sliding block 19. When the sliding block 19 slides, it pulls the spring 18. The spring 18 generates an elastic force to pull the sliding block 19 back to its original position when the sliding block 19 is not pushed by the cam 17. When the sliding block 19 is pushed, the one-way oil inlet pipe 20 takes in oil from the inside of the lubricating oil tank 13 and exits from the one-way oil outlet pipe 4. When the sliding block 19 is not pushed, the spring 18 pulls the sliding block 19 back to its original position, and the one-way oil inlet pipe 20 extracts the lubricating oil inside the lubricating oil tank 13 for oil intake.
