The sealing strip 15 is designed to reduce the overflow and evaporation of lubricating oil.

[0030] like Figures 1 to 2 and Figure 4 As shown, the disassembly and assembly components include two fixing columns 11 and two bolts 12. The bottom ends of the two fixing columns 11 are fixedly connected to the left and right sides of the top of the base 2 10 respectively. The fixing columns 11 are designed to cooperate with the bolts 12 to facilitate the fixation of the base 1 and the shell 2. The insides of the two bolts 12 are respectively threadedly connected to the outsides of the two fixing columns 11. The outsides of the two fixing columns 11 are slidably connected with gaskets 13.
