支撑座与弹簧板之间采用销轴连接，销轴连接的好处是销轴连接用开口销进行锁

The support base and the spring plate are connected by a pin shaft. The advantage of the pin shaft connection is that the pin shaft connection is locked by a cotter pin, which is reliable in operation and convenient in disassembly. The shaft hole of the spring plate and the sleeve, the sleeve and the pin shaft are all over-fitted, and the support seat and the pin shaft are over-fitted. By adopting this connection method, the axial and radial positions of the cold air jacket can be more accurately fixed, and axial and radial deviations of the cold air jacket can be prevented.

The support base and the spring plate are connected by pin shaft, the advantage of pin shaft connection is that the pin shaft connection is locked with an open pin, reliable work, easy removal and so on. The shaft holes of the spring plate are over-fit disassembled between the bush, the bushand and the pin shaft, and the over-over-fit between the support base and the pin shaft. This connection allows the axial and radial positions of the cold air sleeve to be more precisely fixed, preventing axial and radial offsets of the cold air sleeves.

The support seat and spring plate are connected by a pin shaft. The advantage of pin shaft connection is that the pin shaft connection is locked by a cotter pin, which is reliable and easy to disassemble. Excessive fit is adopted between the spring plate shaft hole and the shaft sleeve, between the shaft sleeve and the pin shaft, and between the support seat and the pin shaft. The axial and radial position of the cold air sleeve can be fixed accurately by using this connection method, and the axial and radial deviation of the cold air sleeve can be prevented.<br>
