[0026] In one embodiment, a first through hole 9 is opened on the inner wall of the oil filling pipe 2, and the inner wall of the first through hole 9 is fixedly connected to the outer side of the connecting hose 6. The connecting hose 6 is fixed on the inner wall of the oil filling pipe 2 through the first through hole 9 to realize the filling of lubricating oil into the oil filling pipe 2.

[0027] In one embodiment, a circular groove 805 is provided at the top of the connecting rod 7, and a threaded rod 802 is rotatably installed on the bottom of the inner wall of the circular groove 805, and the top of the threaded rod 802 extends to the top of the connecting rod 7, and a circular plate 801 is fixedly installed on the top of the threaded rod 802, and the outer side of the threaded rod 802 is threadedly connected with an internal threaded tube 803, and two rectangular blocks 804 are fixedly installed on the outer side of the internal threaded tube 803, and the two rectangular blocks 804 are symmetrically arranged, and the outer sides of the two connecting rods 7 are movably sleeved with an adjusting plate 11, and the ends of the two rectangular blocks 804 that are away from each other are fixedly connected to the inner wall of the adjusting plate 11, and the circular plate 801 is rotated to drive the threaded rod 802 to rotate, and the threaded rod 802 is threadedly connected to the internal threaded tube 803, so that the internal threaded tube 803 drives the two rectangular blocks 804 and the adjusting plate 11 to move downward, so as to adjust the distance between the adjusting plate 11 and the upper surface of the oil filling pipe 2, thereby adjusting the amount of lubricating oil added.

[0028] In one embodiment, a bearing 806 is fixedly installed on the bottom of the inner wall of the circular groove 805 , and the inner wall of the bearing 806 is fixedly connected to the outer side of the threaded rod 802 , so that the threaded rod 802 is rotatably installed on the bottom of the inner wall of the circular groove 805 through the setting of the bearing 806 .

[0029] In one embodiment, two guide grooves 807 are provided on the inner wall of the circular groove 805, and the inner wall of the guide groove 807 is in movable contact with the outer side of the rectangular block 804, and the inner wall of the adjustment plate 11 is in movable contact with the outer side of the connecting rod 7. By setting the guide groove 807 and cooperating with the rectangular block 804, the guidance of the adjustment plate 11 during movement is achieved.

[0030] In one embodiment, a touch switch 12 is fixedly installed on the upper surface of the liquid pushing plate 10, and a controller 4 is fixedly installed on one side of the oil storage tank 1. The electrical output end of the touch switch 12 is electrically connected to the electrical input end of the controller 4 through a wire, and the electrical output end of the controller 4 is electrically connected to the electrical input end of the micro liquid pump 5 through a wire. Through the setting of the touch switch 12, when the touch switch 12 contacts the inner wall and top wall of the oil filling pipe 2, the touch switch 12 transmits a signal to the controller 4, and the controller 4 controls the micro liquid pump 5 to start, thereby realizing automatic filling of lubricating oil into the oil filling pipe 2.

[0031] In one embodiment, a second through hole 13 is opened on the top of the inner wall of the oil filling pipe 2, and the inner wall of the second through hole 13 is in movable contact with the outer side of the connecting rod 7. The second through hole 13 allows the connecting rod 7 to move on the top of the inner wall of the oil filling pipe 2.

[0032] When the utility model is working: according to the degree to which the slide block of the bending machine needs to be lubricated, the circular plate 801 is rotated, so that the circular plate 801 drives the threaded rod 802 to rotate. Since the threaded rod 802 is threadedly connected with the internal threaded cylinder 803, the internal threaded cylinder 803 moves downward while the threaded rod 802 rotates. The movement of the internal threaded cylinder 803 also drives the two rectangular blocks 804 to move downward. The moving rectangular blocks 804 drive the adjustment plate 11 to move downward. After the distance between the adjustment plate 11 and the upper surface of the oil injection pipe 2 is adjusted to a suitable distance, the circular plate 801 is stopped from rotating, and the threaded rod 802 is moved downward. The adjusting plate 11 is fixed by the self-locking of the threads of the internal threaded barrel 803, so that the distance between the adjusting plate 11 and the upper surface of the oil filling pipe 2 can be adjusted, thereby adjusting the amount of lubricating oil out of the oil filling pipe 2, effectively ensuring the dosage of the added lubricating oil and avoiding the waste of lubricating oil. Then, the oil filling pipe 2 can be removed from one side of the oil storage tank 1, and the adjusting plate 11 can be pushed, so that the adjusting plate 11 drives the connecting rod 7 to move downward, and the connecting rod 7 drives the liquid pushing plate 10 to move downward, so as to squeeze out the lubricating oil inside the oil filling pipe 2 and fill the lubricating oil to the slide block of the bending machine;

[0033] After the filling is completed, the oil filling tube 2 is placed inside the elastic clamp 3, and the adjustment plate 11 is pulled upward, so that the adjustment plate 11 drives the connecting rod 7 and the liquid pushing plate 10 to move upward. The liquid pushing plate 10 moves upward and drives the touch switch 12 to move upward. When the touch switch 12 contacts the top of the inner wall of the oil filling tube 2, the touch switch 12 transmits a signal to the controller 4. The controller 4 controls the micro-liquid pump 5 to start, so that the micro-liquid pump 5 introduces the lubricating oil inside the oil storage tank 1 into the interior of the oil filling tube 2 through the connecting hose 6. Since the oil filling tube 2 is made of transparent material, when the amount of lubricating oil inside the oil filling tube 2 reaches the required amount, the micro-liquid pump 5 can be turned off, which makes it easy to automatically fill the lubricating oil into the interior of the oil filling tube 2, thereby improving the portability during use.

[0034] The above is only a specific implementation of the utility model, but the protection scope of the utility model is not limited thereto. Any technician familiar with the technical field can easily think of various changes or substitutions within the technical scope disclosed by the utility model, which should be included in the protection scope of the utility model. Therefore, the protection scope of the utility model should be based on the protection scope of the claims.
