Figure 6 , Figure 7It can be seen that the wrench part 4 includes a hand-gripped force-applying part and a connecting part. The connecting part is arranged on the front end of the hand-gripped force-applying part perpendicularly. The connecting head 5 is fixedly connected to the lower end of the connecting part.
