[0022] As a technical optimization of this utility model, by setting the connecting pipe 19 and the filter screen 18, the oil and air entering and exiting the connecting pipe 19 can be filtered to reduce internal impurities. By setting the threaded groove 15 and the threaded ring 16, it is convenient to disassemble and clean the connecting ring 17.
[0023] refer to Figure 1 As shown in the figure, a first limiting ring 20 located outside the adjusting plate 7 is fixedly connected to the inner wall of the diversion pipe 2, and a second limiting ring 21 located inside the adjusting plate 7 is fixedly connected to the inner wall of the diversion pipe 2.
