The movement of the movable plate 302 can enable oiling operation when needed. When not needed, the movable plate 302 is located at the lower end. The top of the movable plate 302 is respectively fixedly connected with the guide block 305 and the positioning block 306. The movement of the movable plate 302 drives the guide block 305 and its positioning block 306 to move. The output end of the driving motor 4 is fixedly connected to the sprocket 6, and the outer wall of the sprocket 6 is meshed with the chain 7. The sprocket 6 and its chain 7 are prior art and will not be explained in detail here.

[0037] Reference Figure 2 , Figure 5 and Figure 6A reset membrane 307 is provided at the bottom of the front end of the oil tank 304. This membrane is usually made of a polymer material and has high strength and elasticity. When the reset membrane 307 is not squeezed by the inside of the oil tank 304, the reset membrane 307 is reset to prevent dust from entering the inner wall of the oil tank 304. The reset membrane 307 is located directly above the chain 7. The setting directly above facilitates the lubricating oil to enter the top of the chain 7, and the transmission through the chain 7 and the sprocket 6 enables both to be lubricated. The inner wall of the movable seat 301 is threadedly connected to the outer wall of the threaded rod 2. The rotation of the threaded rod 2 causes the movable seat 301 to move, and the right end of the screw 303 is threadedly connected to the left end of the box body 1. The threaded connection between the two achieves a fixing effect. The outer wall of the guide block 305 is located on the left side of the positioning block 306, and the top of the positioning block 306 contacts the bottom end of the extrusion block 310. The contact between the two enables the positioning block 306 to move upward. A sliding groove is provided on the outer wall of the guide block 305, and the end of the guide rod 309 contacts the inner wall of the sliding groove. The sliding groove is Z-shaped, and the guide rod 309 can be reset through the sliding groove for subsequent use.

[0039] Reference Figure 7 One end of the connecting spring 504 is fixedly connected to the outer wall of the plug-in column 503, and the other end of the connecting spring 504 is fixedly connected to the inner wall of the connecting plate 502. The outer wall of the plug-in column 503 is slidably connected to the inner wall of the connecting plate 502. The elasticity of the connecting spring 504 makes the plug-in column 503 have a reset and limit function. The left end of the plug-in column 503 is plugged into the right end of the oil tank 304. The two are plugged in to prevent the oil tank 304 from moving up and down. The bottom end of the oil tank 304 is plugged into the inner wall of the positioning ring 501. The two are plugged in to prevent the oil tank 304 from shaking left and right.

[0040] Working principle: When the chain 7 on the saw seat of the panel saw needs to be lubricated, the screw 303 is first rotated to release the limit of the screw 303 on the movable plate 302, and then the movable plate 302 is moved upward, and then the screw 303 is reset to complete the fixing operation, so that the bottom inclined surface of the extrusion block 310 contacts the top inclined surface of the positioning block 306, and then the motor is started to drive the threaded rod 2 to rotate so that the movable seat 301 moves horizontally, the bottom inclined surface of the extrusion block 310 contacts the top inclined surface of the positioning block 306 and the extrusion block 310 is squeezed by the positioning block 306, so that the extrusion block 310 drives the piston 3 08 moves upward, and the upward movement of piston 308 will squeeze the air on the inner wall of oil tank 304, so that the lubricating oil on the inner wall of oil tank 304 moves to squeeze the reset membrane 307, so that the reset membrane 307 opens, and the lubricating oil on the inner wall of oil tank 304 will spray onto the top of chain 7, so that the chain 7 can be oiled, avoiding manual oiling and achieving the purpose of saving time and effort. At the same time, when the motor drives the threaded rod 2 to rotate in the opposite direction, the oil tank 304 will move to the left end, and the guide rod 309 passes through the slide groove opened by the guide block 305, thereby completing the reset and returning the piston 308 to the initial state for the next use.

[0041] When the lubricating oil on the inner wall of the oil tank 304 is used up, the plug-in column 503 is moved to release the limit of the oil tank 304 by the plug-in column 503, and then the oil tank 304 can be moved upward to take out the oil tank 304, and then the oil tank 304 can be oiled or cleaned, and the overall disassembly operation is relatively simple.

[0042] Finally, it should be noted that the above is only a preferred embodiment of the present invention and is not intended to limit the present invention.
