What's the matter with the sleeve installed by the lithium electric wrench always falling off the square sleeve?
Specifications of the square set of lithium electric wrench: 12.7mm,
The silicone O-ring and O-ring [as shown in Figure 2] installed in the square sleeve card slot [as shown in Figure 4] are mainly worn out after a long time of circlip and silicone O-ring [as shown in Figure 3], which will cause the sleeve to be installed very easily, there is no resistance, and if it is normal, there should be a little resistance.
