[0038] Further, one side of the plug block 11 far from the notch 10 is fixedly connected to a first spring 13. The other end of the first spring 13 is fixedly connected to the outer side wall of the positioning rod 9. The top groove 12 is inclined and the groove depth gradually increases along the direction of the positioning rod 9;

[0039] Further, the adjustment structure includes a sliding tube 14 and a push rod 15, the bottom of the inner cavity of the sliding tube 14 is fixedly connected with a first electromagnetic block 16, the top of the inner cavity of the sliding tube 14 is slidably connected with a sliding sleeve 17, the sliding sleeve 17 is fixedly connected with a second electromagnetic block 18, the push rod 15 is divided into a push block 19 and a pull rod 20, the push block 19 is located below the sliding tube 14, one end of the push block 19 away from the sliding tube 14 is in contact with the top groove 12, the pull rod 20 is fixedly connected to the other end of the push block 19, the other end of the pull rod 20 passes through the sliding tube 14, the first electromagnetic block 16 and the second electromagnetic block 18, extends to the top of the sliding tube 14 and is fixedly connected to a limiting plate 21, and the pull rod 20 is fixedly connected to the first electromagnetic block 16;

The provision of the sealing cover 26 can prevent the lubricating oil from leaking into the protective cover body 8. Embodiment 3

[0047] like Figures 1-7 As shown, this embodiment is improved on the basis of the first embodiment as follows: further, a thread is provided on the side wall of the liquid outlet 3, and the detachable locking sleeve includes a rotating ring 32 and a clamping ring 33, the rotating ring 32 is threadedly connected to the liquid outlet 3, a rotating groove 34 is provided on the outer wall of the rotating ring 32, and a ball 35 is rollingly connected on the outer wall of the clamping ring 33, and the ball 35 is adapted to the rotating groove 34, and the outer wall of the rotating ring 32 is rotatably connected to the clamping ring 33 through the cooperation of the rotating groove 34 and the ball 35, and an oil outlet pipe 36 is fixedly connected to the lower surface of the clamping ring 33, and one end of the oil outlet pipe 36 passes through the rotating ring 32 and the clamping ring 33 and is connected to the liquid outlet 3;

[0048] Furthermore, a trolley 37 is provided on the lower surface of the oil storage tank 2, and one end of the oil pipe 5 away from the pump 4 passes through the oil storage tank 2 and extends to the bottom of the inner cavity of the oil storage tank 2. The pump 4 continuously extracts the lubricating oil in the oil storage tank 2 through the oil outlet pipe 36 and sends it to the lubricating oil tank 1, and the oil is sprayed out through the oil outlet pipe 36.

[0049] In this embodiment, the staff holds the clamping ring 33 and screws it onto the liquid outlet 3 by rotating the rotating ring 32. The friction between the rotating ring 32 and the clamping ring 33 can be reduced by the cooperation of the rotating groove 34 and the ball 35, which is convenient for the staff to install. The oil outlet pipe 36 can be clamped on by the provided clamping ring 39.

[0050] In summary, the workflow of the utility model is:

[0051] Before filling, when the liquid outlet 3 needs to be blocked, the staff controls whether the corresponding first electromagnetic block 16 and the second electromagnetic block 18 are energized through the control panel 7. When the corresponding first electromagnetic block 16 and the second electromagnetic block 18 are energized, magnetism will be generated and they will attract each other. The first electromagnetic block 16 moves downward toward the second electromagnetic block 18 under the action of the sliding sleeve 17, and at the same time drives the pull rod 20 to move downward. The pull rod 20 drives the top block 19 to move downward. The top block 19 will squeeze the lower surface of the inner wall of the top groove 12, and the blocking block 11 will be pushed out from the groove 10, so as to accurately control the discharge amount of the liquid outlet 3;

[0052] When the pull rod 20 moves downward, the second spring 22 is compressed, and when the block 11 is pushed out of the notch 10, the first spring 13 is stretched;

[0053] When it is necessary to release the blockage of the liquid outlet 3, the staff cancels the power supply to the corresponding first electromagnetic block 16 and the second electromagnetic block 18 through the control panel 7. When the first electromagnetic block 16 and the second electromagnetic block 18 lose power, the magnetism disappears, and the compressed second spring 22 is reset. During the reset process, it will move upward against the limit plate 21. The limit plate 21 drives the pull rod 20 to move upward, reset the sleeve 17 and the first electromagnetic block 16, and at the same time, the first spring 13 in the stretched state resets and contracts, driving the block 11 to reset it, thereby releasing the blockage of the liquid outlet 3.

[0054] The provided relief groove 29 can prevent excessive pulling of the electrical wire 30 by the first electromagnetic block 16 during movement. Meanwhile, the protective sleeve 27 can isolate a partial section of the electrical wire 30 in the cavity of the lubricating oil tank 1 from the lubricating oil, avoiding safety accidents caused by electric leakage. The provided sealing cover 26 can prevent the lubricating oil from leaking into the protective sleeve body 8.

[0055] After the adjustment is completed, the staff holds the clamping ring 33 and screws it onto the liquid outlet 3 by rotating the rotating ring 32. The cooperation of the rotating groove 34 and the ball 35 can reduce the friction between the rotating ring 32 and the clamping ring 33, facilitating the installation by the staff. During the filling process, the lubricating oil in the storage oil tank 2 is continuously pumped out through the oil outlet pipe 36 by the pumping pump 4 and sent to the lubricating oil tank 1, and the oil is sprayed out through the oil outlet pipe 36. The staff can control the pumping volume and working duration of the pumping pump 4 through the control panel 7. When not filling, the oil outlet pipe 36 can be clamped by the provided clamping ring 39.

[0056] However, as is well known to those skilled in the art, the working principles and wiring methods of the control panel 7 and the pumping pump 4 are common knowledge and are all conventional means or well-known common sense, so they will not be elaborated here. Those skilled in the art can make arbitrary selections according to their needs or convenience.
