Abstract

The utility model relates to a handle structure used for assembling various tool bits such as chisels, crowbars, files, etc. The utility model comprises a handle which is made of plastic and a metal insert, wherein the metal insert is arranged on an inserting connection hole place used for connecting with a tool bit on the handle and plays an enhancement function. Because of the function of the metal insert, the strength of the handle is enhanced, the handle is not easy to crack when being cooled, the strength of the handle is not lowered because of the softening of plastic when being heated, the quality of products is improved effectively and the service lives of the products is prolonged.

Description

Handle ruggedized construction

Technical field

The utility model relates to a kind of handle, refers to a kind of handle arrangement that is used to assemble various tool cutter head (as chisel, crowbar, file etc.) especially.

Background technology

Therefore the handle of present all kinds of instruments all generally adopts the PVC plastics to make, and the handle moulding made from the PVC plastics is enriched very much, profile is very attractive in appearance.But also because the influence of material factor has brought some defectives to handle.The one, to become fragile and contraction distortion after the PVC plastics are caught a cold, thereby can cause that application of force easy fracture, handle increase with gap between cutter head, both combine phenomenon bad, that easily cutter head is come off etc.; The 2nd, after being heated, the PVC plastics want deliquescing, and make handle strength not enough, influence is used.Therefore existing handle arrangement is not suitable for using under low temperature or high ambient conditions.

Summary of the invention

Technical problem to be solved in the utility model is the handle arrangement that provides a kind of intensity, durability and aesthetic property to have both at above-mentioned prior art present situation, overcome the phenomenon of the existing ubiquitous embrittlement of handle, deliquescing etc. thus, to improve the total quality of product, prolong the service life of product.

The utility model solves the problems of the technologies described above the technical scheme that is adopted: this handle ruggedized construction, comprise handle made of plastic, have the spliced eye that is connected usefulness with cutter head on the handle, it is characterized in that in described handle, being provided with the metal insert of humidification.

Described inserts can be located at the spliced eye place of handle.

Open at both ends, the profile of described inserts is " U " shape substantially; The symmetrical both sides on inserts top are respectively equipped with a small convex pillar that plays the role of positioning; Inserts bottom outer wall is made the pushing face-drawing form of tool one tapering; Be shaped on through hole on the inserts wall, the top symmetry is shaped on two open slots.

Described inserts also can be selected an iron ring for use.

Compared with prior art, advantage of the present utility model is: because the effect of metal insert, increased the intensity of handle greatly, be difficult for embrittlement when handle is caught a cold, the Shi Buhui that is heated is because of the softening intensity variation of plastics, effectively improve the quality of products, prolong product service life, do not influence the outward appearance of product simultaneously again, keep the good looking appearance of handle.

Fig. 2 is the schematic perspective view of metal insert.

The specific embodiment

Embodiment describes in further detail the utility model below in conjunction with accompanying drawing.

See also shown in Figure 1ly, handle 1 usefulness PVC plastics of the present utility model are made, and metal insert 2 is embedded in the handle 1, is positioned at handle is connected usefulness with cutter head spliced eye 11 places, is fixed in wherein when the handle injection mo(u)lding.This inserts 2 zinc alloy diecasting moulding, its open at both ends, profile are " U " shape substantially.Wherein the symmetrical both sides on inserts top are respectively equipped with a small convex pillar 22, to play the effect of location; Appropriate position on the inserts wall is shaped on two through holes 23, and interior inflatable plastics are so that inserts and handle are combined into one more firmly; The top symmetry of inserts is shaped on two open slots 21; And for the Shooting Technique demand, the outer wall 24 of inserts bottom is also made the pushing face-drawing form of tool one tapering.

Inserts pattern of the present utility model can be various, except the inserts pattern shown in the present embodiment figure, also can adopt patterns such as iron ring, also can reach the purpose of the utility model handle ruggedized construction.
