The first upper oil pipe 6 and the second upper oil pipe 7 are both inlaid with oiling sponges 8 at the lower part, and the two oiling sponges 8 are respectively fitted with the connecting end 3 and the sealing bearing 4. A movable block 9 is movably installed at the lower part of the oil storage box 5. The movable block 9 is a rectangular structure. The bottom of the movable block 9 is located inside the reducer housing 1. A lower oil groove 10 is provided inside the movable block 9. The lower oil groove 10 is two cylindrical grooves connected to each other. The lower oil groove 10 passes through the side wall of the movable block 9. The reducer housing 1 is provided with connecting grooves 11 at the positions corresponding to the first upper oil pipe 6 and the second upper oil pipe 7. The connecting groove 11 is a cylindrical groove. The connecting groove 11 passes through the side walls of the first upper oil pipe 6 and the second upper oil pipe 7 and is connected to the inside of the first upper oil pipe 6 and the second upper oil pipe 7. A driving mechanism is provided inside the reducer housing 1.

[0026] like Figure 2 and Figure 3As shown, the driving mechanism includes an extrusion plate 12, a return spring 13 and a transmission rod 14. The extrusion plate 12 is a rectangular plate, which is fixedly mounted on the bottom wall of the movable block 9. There are two return springs 13, which are fixedly mounted on the top of the extrusion plate 12 on the left and right sides, and the two return springs 13 are connected to the inner wall of the reducer housing 1. The movable block 9 is movably installed through the extrusion plate 12 and the return spring 13. The transmission rod 14 is a long rod with a rectangular structure, which is fixedly mounted on the side wall of the output shaft 2, and one side wall of the transmission rod 14 is an inclined surface. Through the setting of the driving mechanism, when the output shaft 2 rotates, the output shaft 2 will drive the transmission rod 14 to rotate, and the transmission rod 1 4 is rotated to the position of the squeezing plate 12, and the squeezing plate 12 is squeezed. Since the transmission rod 14 has an inclined surface, the squeezing plate 12 is squeezed and moves upward, so that the upper part of the lower oil groove 10 moves to the inside of the oil storage box 5. At this time, the lubricating oil in the oil storage box 5 will enter the inside of the lower oil groove 10. At the same time, the lower oil groove 10 and the connecting groove 11 will be aligned, and the lubricating oil in the lower oil groove 10 will enter the inside of the connecting groove 11, and then enter the inside of the first upper oil pipe 6 and the second upper oil pipe 7 through the connecting groove 11 respectively.

The glass window 16 is made of transparent material and penetrates the inner and outer side walls of the oil storage box 5. The amount of lubricating oil remaining in the oil storage box 5 can be clearly observed from the outside through the glass window 16. A threaded hole is opened on the top of the oil storage box 5, and a sealing cover 17 is movably installed inside the threaded hole. When the lubricating oil in the oil storage box 5 is insufficient, the sealing cover 17 can be rotated to remove the sealing cover 17 from the oil storage box 5, and then the lubricating oil in the oil storage box 5 can be supplemented;

A transmission shaft 20 is movably installed inside the oil storage box 5. The transmission shaft 20 is a cylindrical structure with threads. The transmission shaft 20 passes through the upper and lower walls of the limiting cover 18 and is threadedly connected with the limiting cover 18. A knob 19 is fixedly installed on the top of the transmission shaft 20. The knob 19 can be rotated. The knob 19 drives the transmission shaft 20 to rotate. The transmission shaft 20 is threadedly connected with the limiting cover 18, and the limiting cover 18 will move downward inside the oil storage box 5. At this time, if the movable block 9 moves upward, it will be sealed by the limiting cover 18, so that the lubricating oil inside the oil storage box 5 cannot enter the inside of the movable block 9, thereby achieving the effect of arbitrarily controlling whether to oil.

[0029] The specific working methods are:

[0030] By providing a driving mechanism, when the output shaft 2 rotates, the output shaft 2 will drive the transmission rod 14 to rotate. When the transmission rod 14 rotates to the position of the extrusion plate 12, the extrusion plate 12 will be squeezed. Since the transmission rod 14 has an inclined surface, the extrusion plate 12 will move upward when squeezed, so that the upper part of the lower oil groove 10 moves to the inside of the oil storage box 5. At this time, the lubricating oil in the oil storage box 5 will enter the inside of the lower oil groove 10. At the same time, the lower oil groove 10 and the connecting groove 11 will be aligned, and the lubricating oil in the lower oil groove 10 will enter the inside of the connecting groove 11, and then enter the first upper oil pipe 6 and the second upper oil pipe 7 respectively through the connecting groove 11. The oiling sponges 8 on the first upper oil pipe 6 and the second upper oil pipe 7 will apply the lubricating oil to the connecting end 3 and the sealed bearing 4, thereby lubricating the connecting end 3 and the sealed bearing 4.
