The interior of the placement bin 4 is fixedly connected to a filter plate 5, and the top surface of the filter plate 5 is fixedly inlaid with a filter net 7. A clearance groove 9 is opened on the left side of the placement bin 4, and a transparent plate 10 is fixedly connected to the inside of the clearance groove 9.

The top surfaces of the front bracket 11 and the rear bracket 2 are both provided with through holes, and the two connecting pipes 3 respectively pass through the two through holes and fit therewith. The connecting pipes 3 are hoses.

[0026] Specifically, the connecting pipe 3 is inserted into the through hole, and the lubricant is poured into the storage bin 4. The lubricant is filtered by the filter 7, so that impurities are retained on the top surface of the filter plate 5. The lubricant after passing through the filter 7 is transported by the connecting pipe 3 and enters the interior of the front bracket 11 and the rear bracket 2 for lubrication. The transparent plate 10 allows users to understand the amount of lubricant stored in the storage bin 4.

[0027] In this embodiment, a sealing assembly is provided on the placement bin 4, and the sealing assembly includes a sealing plate 8. The sealing plate 8 is placed on the top surface of the placement bin 4. The bottom surface of the sealing plate 8 is fixedly connected to a rubber ring 6 with one end extending to the inside of the placement bin 4. Two positioning holes 18 are opened on the top surface of the placement bin 4. The bottom surface of the sealing plate 8 is fixedly connected to two positioning rods 17, one end of which extends to the inside of the two positioning holes 18 respectively.

[0028] The positioning rod 17 and the positioning hole 18 are clearance-fitted, the rubber ring 6 is a rectangular ring, and the outer peripheral wall of the rubber ring 6 fits the inner peripheral wall of the placement chamber 4 .
