将机器上的原套筒拆除，用一字螺丝刀拧松两边螺丝，取下旧套筒组建。

Firstly, remove the original sleeve from the machine, loosen the screws on both sides with a flat screwdriver, and remove the old sleeve assembly.

然后安装新套筒，拿出准备好的m22套筒组建，用螺栓将内套筒从组建中顶出，将套筒组建中的内外套筒分离。

Then install a new sleeve, take out the prepared M22 sleeve assembly, use bolts to push the inner sleeve out of the assembly, and separate the inner and outer sleeves in the sleeve assembly.

然后将内套筒插入机器，注意按住内套筒不被弹簧顶出。再将外套筒对准凹槽装入机器，注意过程中不要让套筒被弹簧顶出。

Then insert the inner sleeve into the machine, being careful not to push it out by the spring. Align the outer sleeve with the groove and install it into the machine, being careful not to let the sleeve be pushed out by the spring during the process.

发现外套筒没有安装到位怎么办？这时用准备好的扭剪螺栓插入内套筒，同时按动螺栓使套筒安装到位。

What should I do if I find that the outer sleeve is not installed properly? At this point, insert the prepared shear bolts into the inner sleeve and press the bolts to install the sleeve in place.

按住套筒的同时拧紧套筒两边的螺丝，这样套筒就更换好啦。

Tighten the screws on both sides of the sleeve while holding it down, so that the sleeve can be replaced.
