When the electromagnet 158 ​​is powered on, a strong magnetic force is generated, which can magnetically attract the iron cylinder 157 to drive the moving frame 154 to slide stably along the surface of the guide rod 153. This causes the spring 156 to deform and move the elastic plug 155. Under the pressure of the inner wall of the guide hole of the oil storage box 152, the elastic plug 155 can move and eventually detach from the guide hole. Under the flow of the guide pipe 151, the lubricating oil can come into contact with the oil suction sleeve 150 to lubricate the hydraulic cylinder 11 and ensure the good extension and retraction effect of the hydraulic cylinder 11.
