Abstract

The utility model relates to a hammer for striking, and aims to solve the technical problem of providing a hammer having the advantages of low vibration, high safety performance and convenience in manufacture. The technical scheme includes that the shockproof hammer comprises a hammer head and a hammer handle connected therewith, and is characterized in that the hammer head is fixedly connected with the hammer handle through a spiral spring. The hammer handle includes two sections, two ends of the hammer handle left section are respectively fixed to the hammer head and one end of the spiral spring, and the hammer handle right section is fixed to the other end of the spiral spring. The hammer handle is made of metal, and fixed to the hammer head by means of welding. The spiral spring is wrapped on the hammer handle and fixed by means of welding.

Description

A kind of shockproof hammer

Technical field

The utility model relates to a kind of hand-operated tools, in particular for the hammer that knocks.

Background technology

Hammer is one of basic hand-operated tools, is widely used in all kinds of constructions, repairs the place.Conventional hammer is made up of tup, the hammer handle of fixedlying connected with tup; Common hammer handle mostly is bamboo and wood materials greatly and makes, and the deficiency of this structure is: during use vibration sense comparatively strong, hinder hand easily, and the comparatively difficulty that is connected of hammer handle and tup, easy again loose or dislocation thereby have certain danger during use.

The utility model content

Technical problem to be solved in the utility model is to overcome above-mentioned the deficiencies in the prior art, and a kind of improvement of hammer is provided, and vibratory sensation was little when this hammer should have use, security performance is high and make characteristics easily.

The technical solution adopted in the utility model is: a kind of shockproof hammer comprises tup, the hammer handle that is connected with tup; It is characterized in that described tup passes through a helical spring and fixedlys connected with hammer handle.

Described hammer handle is divided into two sections, and wherein the two ends of left side section hammer handle are separately fixed on the tup and a helical spring end, and right section hammer handle is fixed on the helical spring other end.

Described hammer handle is a metal handle, and hammer handle and tup welding are fixing.

Described helical spring looping is fixed on hammer handle and by welding.

The beneficial effects of the utility model are: owing to be provided with helical spring between hammer handle and the tup, thereby the vibration that produces when using tup to knock obtained good buffering and elimination, and operator's feel is comparatively gentle; And the metal handle is connected with tup by welding manner, has guaranteed that tup can not come off, and security performance is guaranteed fully; In addition, the structure of this hammer is also simple, and directly outsourcing of helical spring makes things convenient for so make also.

The specific embodiment

This shockproof hammer comprises tup 1, the hammer handle that is connected with tup, and these are similar with conventional hammer; Change of the present utility model is that described tup is fixedlyed connected with hammer handle by a helical spring 2.

For ease of helical spring fixing, described hammer handle adopts metal handle (the preferred handspike); Like this, described hammer handle can be divided into two sections (as shown in the figure), and the left end of left side section hammer handle 3-1 wherein is weldingly fixed on (perhaps clear-cut and tup is made one) on the tup, and the left end of right-hand member and helical spring 2 is fixed; Right section hammer handle 3-2 then is fixed on the right-hand member of helical spring 2.

Hammer handle and helical spring fixed form can be known by Fig. 1, Fig. 2: an end car of hammer handle is made and the matched face of cylinder of helical spring interior circle, then helical spring is set on (being the end of helical spring looping at hammer handle) on this face of cylinder, by welding helical spring and this face of cylinder is fixed as one at last.Because helical spring two ends wear fixing one section hammer handle respectively, should keep suitable distance so be inserted between the end face of two hammer handles in the helical spring, to provide vibration damping needed space.

Fig. 3, shown in Figure 4 be the embodiment that is applied to carpenter's hammer; Compare with previous embodiment, helical spring mounting means is identical among this embodiment, and difference is; The right side of left side section hammer handle 3-1 also is shaped on a jack, then is shaped on the plug 3-3 that stretches into aforementioned jack on the end face of right section hammer handle 3-2; Like this, the goat's horn tup 5 of this carpenter's hammer also can be advantageously used in pulling out a nail.Nature should keep suitable gap between plug and the jack, to possess corresponding vibration-damping function.Usually, the gap is big more, and vibration-damping function is obvious more.Concrete gap data can be determined as required.

Claims

1. a shockproof hammer comprises tup (1), the hammer handle that is connected with tup; It is characterized in that described tup passes through a helical spring (2) and fixedlys connected with hammer handle.

2. a kind of shockproof hammer according to claim 1 is characterized in that described hammer handle is divided into two sections, and wherein the two ends of left side section hammer handle (3-1) are separately fixed on the tup and an end of helical spring (2), and a right section hammer handle is fixed on the helical spring other end.

3. a kind of shockproof hammer according to claim 2 is characterized in that described hammer handle is a metal handle, and hammer handle and tup welding are fixing.

4. according to claim 2 or 3 described a kind of shockproof hammers, it is characterized in that described helical spring looping is also fixing by welding on hammer handle.
