Description
Technical field
The invention belongs to hand-operated tools field, be specifically related to a kind of hammer.
Background technology
Hammer is a kind of application hand-operated tools very widely, generally comprises by steel or other metal tups and handle two parts of being made up as glass fibre etc. of wood or other composites.One end of tup is the impact portion with impact surface, and the other end is generally due to the goat's horn portion for nail nipping.Have hammer hole at the middle part of tup, one end of handle is inserted by interference fit among the hammer hole of tup, thus tup and handle is fixed together.
When making to hit with a hammer object, can occur accurately not hit due to the impact surface of tup to wait to impact object, and make to treat that impact object strikes the situation of handle near tup position, being easy to of this situation causes breaking of wooden handle, or the wearing and tearing of fiberglass handles, produce the harmful substances such as silvalin powder, Paris white, healthy, the pollution environment around of harm operating personnel.If continue to use such hammer, handle neck can fracture, and causes tup to be separated with handle, can produce greatly potential safety hazard, and shortens the service life of hammer.
In order to prevent the generation of this situation, some manufacturers adopt PP(Polypropylene, polypropylene) coated handle near the position of tup, to protect handle main body.But when in time impacting object and strike handle near tup position; be easy to PP is fallen in; cause PP damaged after repeatedly using; handle main body is made to be in not shielded state; thus the problem of breaking or wearing and tearing of handle main body can not be solved; still there is greatly potential safety hazard, also can shorten the service life of hammer simultaneously.
Summary of the invention
In view of above-mentioned defect, an object of the present invention is to provide a kind of hammer, this hammer can prevent coated protective layer PP damaged, thus ensures that hammer handle main body is not broken, do not worn and torn.Another object of the present invention is to provide a kind of preparation method of hammer.
To achieve these goals; the invention provides a kind of hammer, comprise one handle and the tup being fixed on handle one end, handle comprises one handle main body; handle is provided with protective metal shell near the position of described tup, is provided with filling protective between handle main body and protective metal shell.
Such hammer handle main body, filling protective and protective metal shell three combine securely; in shots; wait to impact object if the impact surface of tup is not accurately hit; and make to treat that impact object strikes handle near tup position; protective metal shell can protect filling protective indeformable not damaged; thus make filling protective give full play to the effect of its protection handle main body; handle main body is not constantly split do not wear and tear; because this eliminating the potential safety hazard in operation; and clean environment firendly, substantially prolongs the service life of hammer simultaneously.
