When the hammer head and other tools are used to hit the handle 2, the tool first contacts the knocking part 5 because the thickness of the knocking part 5 is greater than that of the handle 2, so as to prevent the hammer head from directly colliding with the handle 2 with small thickness and causing the deformation and damage of the handle 2, the large thickness of the knocking part 5 can improve the contact area between the handle 2 and the hammer head, the hammer head can hit the handle 2 more accurately, the loss of force can be reduced, and the disassembly speed of the end cover is further improved.
