The inner wall of the oil replenishing pipe 203a is provided with a first turning groove 203e-1, and the inner wall of the first turning groove 203e-1 is provided with a rotating groove 203e-2.

[0041] Furthermore, the invention also includes a transmission assembly 204, the transmission assembly 204 is arranged on the outer side of the oil replenishing pipe 203a, the transmission assembly 204 includes a rotating rod 204a arranged in the rotating groove 203e-2, a pushing block 204b arranged on the rotating outer side, a second connecting handle 204c arranged on the pushing block 204b, a floating portion 204d arranged on the second connecting handle 204c, and a second turning groove 204e arranged on the outer wall of the oil replenishing pipe 203a; the second connecting handle 204c and the floating portion 204d cooperate with each other, the second connecting handle 204c is rotatably connected in the second turning groove 204e, and the rotating groove 203e-2 A rotating rod 204a is rotatably connected to the inner part through a bearing, and a pushing block 204b is fixedly installed near the center of the outer part of the rotating rod 204a. The pushing block 204b is in the shape of a quarter of a circle. The pushing block 204b and the ring 203e-4 are adapted to each other and cooperate with each other. A second connecting handle 204c is fixedly connected to the outer part of the rotating rod 204a near the two ends where there is no pushing block 204b. Four groups of second steering grooves 204e are opened on the outer wall of the oil replenishing pipe 203a. The second connecting handle 204c is rotatably connected to the second rotating groove 203e-2 with the rotating rod 204a as the center. The first connecting handle 203e-3 is rotatably connected to the rotating rod 204a. 04a is connected to the first rotating groove 203e-2 for center rotation, a guide rod 204d-1 is fixedly connected between one side of the two second connecting handles 204c, and a buoy 204d-4 is floatingly connected in the oil storage chamber 102b. The buoy 204d-4 presents a hollow circular ring-shaped closed structure. The buoy 204d-4 will float on the surface of the hydraulic oil. Because the density of the hydraulic oil is greater than that of the air, the buoy 204d-4 will float on the surface of the hydraulic oil. This is because the density of the buoy 204d-4 is smaller than that of the liquid, so it will be affected by the buoyancy of the surface of the hydraulic oil. The inner wall of the buoy 204d-4 is fixedly installed with a second The surface of the rotating seat 204d-2 and the second rotating seat 204d-2 is provided with a movable groove 204d-3, and the movable groove 204d-3 is elliptical. The guide rod 204d-1 is movably connected in the movable groove 204d-3 and can move within a specific range. When the hydraulic oil in the hydraulic oil tank 101 is sufficient, the upper part of the buoy 204d-4 will be against the outer wall of the oil storage tank 201 near the bottom, and the lower end side of the pushing block 204b will be in contact with the other side surface of the lower end of the ring 203e-4, and the blocking ball 203b has intercepted the oil supply pipe 203a.

[0042] During use, the hydraulic oil is continuously consumed. When the oil replenishment level 102c is reached, the horizontal plane of the hydraulic oil tank will be at the same level as the bottom of the buoy 204d-4. As the hydraulic oil decreases, the buoy 204d-4 will move vertically downward. When the buoy 204d-4 moves downward for a certain distance, the second rotating seat 204d-2 drives the guide rod 204d-1 to move through the movable groove 204d-3 so that the second connecting handle 204c rotates 45 degrees with the rotating rod 204a as the center. At this time, the second connecting handle 204c will drive the rotating rod 204a to rotate 45 degrees. 4a rotates 45 degrees counterclockwise. At this time, the position of the first connecting handle 203e-3 is temporarily fixed, and the lower end of the push block 204b is separated from the other side surface of the lower end of the ring 203e-4, and rotates 45 degrees counterclockwise, so that the upper end of the push block 204b and the other side of the upper end of the ring 203e-4 contact each other, and begin to apply a counterclockwise thrust to the ring 203e-4, driving the first connecting handle 203e-3 to rotate counterclockwise. As the oil level line of the hydraulic oil continues to drop, the buoy 204d-4 will continue to move downward. When the second connecting handle 20 When the second connecting handle 204c is rotated 45 degrees counterclockwise, the lower end surface of the second connecting handle 204c abuts against the inner wall of the second turning groove 204e, and the second connecting handle 204c can no longer rotate, which makes the buoy 204d-4 temporarily move down and the position is fixed. The buoy 204d-4 has no buoyancy, but its own gravity will keep the rotation angle of the second connecting handle 204c unchanged. As the second connecting handle 204c rotates and drives the rotating rod 204a to rotate, the pushing block 204b will push the ring 203e-4 counterclockwise. It rotates 45 degrees clockwise, and then under the push of the push block 204b, the first connecting handle 203e-3 rotates 45 degrees counterclockwise. Under the rotation of the four groups of first connecting handles 203e-3, the first rotating seat 203d is simultaneously displaced upward, lifting the blocking ball 203b, so that the blocking ball 203b is separated from the inner wall of the oil replenishing pipe 203a, and the hydraulic oil in the receiving chamber 202a will flow downward from the gap between the inner wall of the oil replenishing pipe 203a and the blocking ball 203b, and enter the oil storage chamber 102b to provide oil supply, thereby achieving the effect of autonomous oil replenishment.
