The present application uses an installation mechanism to select multiple handles, and the multiple handles can be installed on the hammer and the flat shovel as needed, which can not only ensure the selectability of the handles, but also save the number of handles.
[0012] 2. When the installation mechanism in the present application is in use, an external force is applied to reduce the distance between the handle and the inner ring, that is, the compression spring is fully compressed until the matching protrusion enters the interior of the entry groove until it moves to the bottom of the entry groove, and then the inner ring and the ring sleeve are relatively rotated. At this time, the matching protrusion moves inside the moving groove until the matching protrusion moves to the position of the clamping groove, and then the inner ring and the ring sleeve are relatively separated so that the matching protrusion enters the interior of the clamping groove to achieve the limiting effect on the matching protrusion. At this time, the external force applied to the handle and the inner ring is released, and the compression spring is pressed. Under the action of, the matching protrusion enters the interior of the clamping groove, and at this time the matching protrusion is in a state of being tightly pressed against the bottom end of the clamping groove, thereby ensuring the stable connection between the inner ring and the ring sleeve. In this process, the matching protrusion can be located inside the clamping groove through the compression spring, thereby preventing the matching protrusion from easily detaching from the clamping groove, thereby ensuring the stability of the installation of the handle, the flat shovel and the hammer respectively. At the same time, it is only necessary to apply external force to overcome the effect of the compression spring to achieve rapid installation, and it is also possible to avoid the problem of detachment caused by vibration due to simple connection methods such as bolt connection.
