The first bracket 31 is connected to the inner wall of the base 2, and the second bracket 32 ​​is connected to the first bracket 31. The connecting section 33 is used to install the connecting section 33. The adjusting nut 4 is used to adjust the position of the connecting section 33 to facilitate the fixing of the lubricating oil pump 1.

[0030] The second bracket 32 ​​includes an angle steel 321, a backing plate 322, and a bracket panel 323. The backing plate 322 is fixedly connected to the surface of the first bracket 31. The angle steel 321 is fixedly connected to the surface of the backing plate 322. The end of the angle steel 321 away from the backing plate 322 is fixedly connected to the bracket panel 323. The second bracket 32 ​​is composed of the angle steel 321, the backing plate 322, and the bracket panel 323, which is used to mount the bracket panel 323 and facilitate adjustment by staff.
