BRIEF DESCRIPTION OF THE DRAWINGS

[0012] Figure 1 It is a schematic diagram of the structure of the utility model;

[0013] Figure 2 It is a front view of the structure of the utility model.

[0014] Among them, 1 is a frame body, 2 is a wheel body, 3 is an automatic wire pressing device, 4 is an adjusting balance mechanism, 5 is a storage box, 6 is a piston, 7 is a through hole, 8 is a push rod, 9 is a handle, 10 is a spacer block, 11 is a first spring, 12 is a blocking groove, 13 is a stopper, 14 is a second spring, and 15 is a movable groove. DETAILED DESCRIPTION

[0015] like Figure 1-2 As shown, the embodiment of the utility model provides a multi-needle elastic thread passing tug with adjustable axis center distance, including a frame body 1, a wheel body 2 is arranged inside the frame body 1, an automatic thread pressing device 3 is arranged at the bottom of the frame body 1, and an adjustment balance mechanism 4 is arranged on the surface of the automatic thread pressing device 3. A storage box 5 is fixedly connected to the inner wall of the frame body 1, a liquid outlet is arranged at the bottom of the storage box 5, and lubricating liquid is stored in the storage box 5. A through hole 7 connected to the lower surface is opened on the upper surface of the frame body 1, a piston 6 is movably connected to the inside of the storage box 5, and a push rod 8 is fixedly connected to the upper surface of the piston 6. A handle 9 is fixedly connected to the top, and a first spring 11 is fixedly connected to the lower surface of the handle 9. A movable groove 15 is provided on the upper surface of the frame 1, and a spacer block 10 is movably connected inside the movable groove 15. A blocking groove 12 is provided on the inner wall of the movable groove 15, and a block 13 is movably connected inside the blocking groove 12. The right side of the block 13 is fixedly connected to the left side of the spacer block 10, the upper surface of the spacer block 10 is fixedly connected to the bottom end of the first spring 11, and a second spring 14 is fixedly connected to the lower surface of the spacer block 10, and the bottom end of the second spring 14 is fixedly connected to the inner bottom wall of the movable groove 15.

[0016] Working principle: when lubrication is needed, press the handle 9 downward, the handle 9 will push the piston 6 downward through the push rod 8, so that the lubricating liquid inside the storage box 5 flows downward, and the lubricating liquid flows along the inner wall of the frame 1 to the side of the wheel body 2 for lubrication, and then release the handle 9. At this time, the second spring 14 and the first spring 11 are reset at the same time, so that the piston 6 moves upward. At this time, the inside of the storage box 5 is in a negative pressure state, so that the lubricating liquid stops flowing out.
