Furthermore, the description of the upper, lower, left, right, etc. used in the present invention is only relative to the mutual positional relationship of the components of the present invention in the drawings.

Furthermore, unless defined otherwise, all technical and scientific terms used herein have the same meaning as commonly understood by one of ordinary skill in the art. The terminology used in the description herein is for the purpose of describing particular embodiments only and is not intended to be limiting of the invention. As used herein, the term "and/or" includes any combination of one or more of the associated listed items.

Referring to fig. 1, the antidetonation handle of a knife of this embodiment is including blind rivet 1, go up handle of a knife 2, lower handle of a knife 3, shock-absorbing column 4, high temperature resistant cushion 5, steel gasket 6, elastic element 7 and locking screw 8, the first end of lower handle of a knife 3 (the left end of lower handle of a knife 3 is its first end) and last handle of a knife 2 fixed connection, the second end of lower handle of a knife 3 (the right-hand member of lower handle of a knife 3 is its second end) mountable cutter, the cutter can adopt the mode of cup jointing locking to fix on the second end of lower handle of a knife 3, lower handle of a knife 3 is opened along the axial has holding hole 31, the one end and the external intercommunication in holding hole 31, be provided with shock-absorbing column 4 in holding hole 31, shock-absorbing column 4 is in axial direction and lower handle.

Specifically, the left end of shock absorber 4 is connected with lower handle of a knife 3 through elastic element 7, and the right-hand member of shock absorber 4 supports with lower handle of a knife 3 through high temperature resistant cushion 5 and holds, and elastic element 7 centre gripping is between locking screw 8 and shock absorber 4, for make power evenly conduct on shock absorber 4, the left end of shock absorber 4 loops through high temperature resistant cushion 5, steel pad 6 supports with elastic element 7 and holds, and high temperature resistant cushion 5 of shock absorber 4 right-hand member supports with lower handle of a knife 3 through steel pad 6 and holds. In this embodiment, the elastic element 7 is a compression spring, and the high temperature resistant elastic pad 5 is made of rubber. Thus, when the tool transmits vibration to the lower tool shank 3, the vibration energy is dissipated in the elastic extension of the shock-absorbing stud 4 and the lower tool shank 3, so that the vibration is attenuated.

Further, the density of the shock absorption column 4 can be made to be greater than that of the lower tool shank 3, in the embodiment, the shock absorption column 4 is made of tungsten, and the density of the tungsten is 19.35g/cm³Greater density than typical tool materials, heavier volume of tungstenThe amount is greater than the weight of the cutter material with the same volume, so that the integral inertia of the cutter handle is increased, and the cutter handle is not easy to vibrate.
