[0023] An oil storage shell 6 arranged on one side of the top of the sliding seat body 4, both the surface of the slide bar 5 and the screw rod 3 are sleeved with oil injection rings 7, which facilitates the oil guiding work, and an outer shell 10 is installed on the surface of the base 1.
[0024] One side of the oil injection ring 7 close to the sliding seat body 4 is fixedly connected to the sliding seat body 4. A connection groove 8 is opened inside the oil injection ring 7, which facilitates the diversion of lubricating oil. Reinforcement plates 9 are fixedly connected to both sides of the oil storage shell 6. The fixed connection between the reinforcement plates 9 and the sliding seat body 4 can strengthen the connection strength between the oil storage shell 6 and the sliding seat body 4. The bottom of the reinforcement plate 9 is fixedly connected to the sliding seat body 4. A feed shell 11 is arranged on the top of the oil storage shell 6, which facilitates the diversion of lubricating oil into the interior of the oil storage shell 6. The sealing cover 12 and the rubber strip 13 cooperate to facilitate the sealing of the feed shell 11, and at the same time, it can also prevent the loss of the sealing cover 12. A sealing cover 12 is arranged on the top of the feed shell 11, and a rubber strip 13 is fixedly connected between one side of the sealing cover 12 and the sliding seat body 4.
[0025] A drain pipe 14 is connected to the front side of the oil storage shell 6. A sealing plug 15 is arranged at the rear side inside the drain pipe 14. A push rod 16 is fixedly connected to the front side of the sealing plug 15. A spring 17 is fixedly connected between the front side of the sealing plug 15 and the inner wall of the drain pipe 14.

When the motor 2 is driven, the screw rod 3 will cooperate with the sliding seat body 4 to move on the surface of the sliding rod 5. When the sliding seat body 4 moves to be close to the inner wall of the base 1, at this time, the protective pad 18 is pressed to drive the push rod 16 to move and at the same time make the sealing plug 15 move inside the drain pipe 14. However, when the sealing plug 15 moves, the spring 17 will also be stretched. At this time, the drain pipe 14 will be opened, and the oil in the oil storage shell 6 will be discharged into the interior of the oil injection ring 7 through the guide pipe 19, the first pipe 20 and the second pipe 21, so as to lubricate the screw rod 3 and the sliding rod 5.
