Detailed ways

A number of preferred embodiments are listed now and the structural features of the utility model are described with reference to the accompanying drawings.

Fig. 2-Fig. 11 is the first kind of embodiment of the present utility model, comprises:

A knocking assembly 20, made of steel or other metal materials, has a knocking part 21, the right side of the knocking part 21 is provided with a nail pulling part 22, and a protruding part is extended below the knocking component 20 23. A first recess 24 is formed on the top of the protrusion 23, and a second recess 25 is correspondingly formed at the bottom. A first stopper 241 is provided on the upper right side of the first recess 24. The second recessed portion 25 is provided with a second stop portion 251 relative to the first stop portion 241. In addition, a first through hole 231 is provided at the lower end of the protrusion portion 23. From the upper right side of the protrusion portion 23 A first accommodating space 232 is opened to the left.

A holding assembly 30 has a holding portion 31 for the user to hold, and a first plate portion 32 extends upward from the right side of the upper end of the holding portion 31 , from the bottom edge of the first plate portion 32 A second plate portion 33 is extended to the left, and a third plate portion 34 is extended to the left from the top edge of the first plate portion 32 corresponding to the second plate portion 33, thereby forming a receiving groove 35 The predetermined position of the second plate part 33 is provided with a second through hole 331 relative to the first through hole 231 of the protrusion part 23, and the third plate part 34 is relatively opposite to the first through hole 231 and the second through hole 231. The through hole 331 is provided with a third through hole 341, the right top of the second plate portion 33 forms a third stop portion 332, and the right top of the third plate portion 34 corresponds to the third stop. The stop part 332 forms a fourth stop part 342, and the protrusion part 23 of the striking assembly 20 is inserted into the receiving groove 35, the second plate part 33 is located in the second concave part 25, and the third plate part 34 is located in the first recessed portion 24 .

A pivot assembly 40 includes a pin 41 , the pin 41 passes through the third through hole 341 , the first through hole 231 and the second through hole 331 sequentially, and then is positioned by a fastener 42 .

A buffer assembly 50 includes a first compression spring 51 and a positioning pin 52, the first compression spring 51 is accommodated in the first accommodation space 232 of the knocking assembly 20, the left end of the first compression spring 51 pushes Made on the left side of the first accommodating space 232, the positioning pin 52 is inserted into the inner right section of the first compression spring 51, and the right end of the positioning pin 52 is pushed against the left end surface of the first plate part 32 The purpose of setting the positioning pin 52 is to be more stable when the first compression spring 51 is deformed under force, but the positioning pin 52 is not absolutely necessary.

As shown in Fig. 10 and Fig. 11, in the normal state when not knocking, the fourth stop portion 342 of the grip assembly 30 abuts against the first stop portion 241 of the knock assembly 20, and the third stop portion 342 The stop portion 332 abuts against the second stop portion 251 .
