[0014] (III) Beneficial Effects

[0015] This utility model provides a stable electric wrench striking block assembly, which has the following beneficial effects:

[0016] 1. This stable electric wrench striking block assembly, through the setting of the lubrication component, allows for the addition of a certain amount of lubricating oil into the oil reservoir during use. When the oil pump is started, the oil pump draws the lubricating oil from the oil reservoir into the connecting pipe, and from the connecting pipe into the device, lubricates the striking block body. This can effectively reduce the wear of the striking block assembly, thereby extending the service life of the component.

[0017] 2. This stable electric wrench striking block assembly, through the setting of the sealing component, ensures that when the housing is connected to the electric wrench, the electric handle is in contact with the sealing gasket, so that the compression spring is in a compressed state. The compression spring provides a reaction force to the sealing gasket, making the sealing gasket fit tightly with the electric wrench. This can prevent the lubricating oil inside the device from leaking out from the connection port, and can also prevent external dust or water stains from entering the inside of the device, thus ensuring the normal use of the device.
