Abstract

The utility model discloses a damping hammer which comprises a hammer and a handle, wherein the handle is divided into two parts, namely, a hammer section handle and a holding section handle; the outer surfaces of the two section handles are both made of rubber materials; an elastic steel rod with a thread at the front end is arranged in the hammer section handle; the front end of the elastic steel rod penetrates into the hammer; the hammer and the hammer section handle are connected together through a nut on the hammer; and the hammer section handle and the holding section handle are fixedly connected through a metal spiral spring pipe. After the structure is adopted by the damping hammer, a rubber layer is arranged on the surface of the handle, so that the damping hammer can more effectively absorb vibration, the vibration and impact to the arm of a user caused by the handle during a hammering process are obviously reduced, the labor efficiency is increased and the labor fatigue is relieved. The damping hammer is long in service life and is convenient to use.

Description

A kind of shock absorption hammer

Technical field

The utility model relates to a kind of hammer, particularly relates to a kind of shock absorption hammer.

Background technology

The handle of existing hammer mostly is rigidity (such as metal) or near the object of rigidity (such as waddy).When knocking, the suffered a part of impulsive force of hammer part passes to operator's palm by handle, make operator's palm and arm be given a shock effect.When impulsive force stronger, though or impulsive force do not knock more frequently occasion by force, can be to operator's healthy generation harmful effect.People generally are comprised of hammer part and wooden handle portion at the hammer that cut into a mountain rock drilling or hammer stone use at present, what the hammer hammering produced on the hard object such as steel fibre or stone reaches on the staff by handle than big bang power, makes the people be subject to larger vibrations and impact.For this reason, people adopt bamboo to make handle with vibrations and impact between minimizing staff and the handle, and use the hammer operation efficiency of this bamboo handle lower, and fragile, use also inconvenient.

Summary of the invention

For above-mentioned the deficiencies in the prior art part, the utility model provides a kind of shock absorption hammer, can effectively address the above problem.

The technical solution adopted in the utility model is: a kind of shock absorption hammer, comprise hammer and handle, described handle is divided into hammer section handle and holding section handle two parts, two sections handle outer surfaces all adopt elastomeric material to make, the threaded steel elastic rod of front end is housed in the hammer section handle, steel elastic rod front end penetrates in the hammer, and by the nut that is contained on the hammer hammer and hammer section handle is linked together, and is fixedly connected with the metal coil spring pipe between described hammer section handle and the holding section handle.

As preferably, holding section handle outer surface has the annular concave-convex line.

As preferably, described holding section handle is longer than hammer section handle.

The utility model has the advantage of: after adopting said structure, handle surfaces is provided with rubber layer, therefore it can absorb vibration preferably, and handle causes to human arm when significantly reducing hammering chatter and impact, and can raise labour efficiency, thereby reach the fatigue that lightens one's labor.The long service life of this shock absorption hammer, and easy to use.

Description of drawings

Fig. 1 is structural representation of the present utility model.

The specific embodiment

The utility model is described in further detail below in conjunction with accompanying drawing and instantiation.

As shown in Figure 1, a kind of shock absorption hammer, comprise hammer 1 and handle, described handle is divided into hammer section handle 2 and holding section handle 3 two parts, two sections handle outer surfaces all adopt elastomeric material to make, and the threaded steel elastic rod 4 of front end is housed in the hammer section handle 2, and steel elastic rod 4 front ends penetrate in the hammer 1, and by the nut that is contained on the hammer 1 hammer 1 and hammer section handle 2 are linked together, be fixedly connected with metal coil spring pipe 5 between described hammer section handle 2 and the holding section handle 3; Holding section handle 3 outer surfaces have annular concave-convex line 6; Described holding section handle 3 is longer than hammer section handle 2.

In the utility model, the threaded steel elastic rod 4 of front end is housed in hammer section handle 2, hammer section handle 2 front ends are penetrated in the hammer 1, and the nut that will be contained on the hammer 1 is tightened on the steel elastic rod 4, hammer 1 and hammer section handle 2 are fixed together.For fear of holding 3 slippages of holding section handle, the utility model has annular concave-convex line 6 at holding section handle 3 outer surfaces.Be fixedly connected with handle causes to human arm when having reduced hammering chatter and impact between hammer section handle 2 and the holding section handle 3 with metal coil spring pipe 5.

Claims

1. shock absorption hammer, comprise hammer and handle, it is characterized in that: described handle is divided into hammer section handle and holding section handle two parts, two sections handle outer surfaces all adopt elastomeric material to make, the threaded steel elastic rod of front end is housed in the hammer section handle, steel elastic rod front end penetrates in the hammer, and by the nut that is contained on the hammer hammer and hammer section handle is linked together, and is fixedly connected with the metal coil spring pipe between described hammer section handle and the holding section handle.

2. a kind of shock absorption hammer according to claim 1, it is characterized in that: holding section handle outer surface has the annular concave-convex line.

3. a kind of shock absorption hammer according to claim 1, it is characterized in that: described holding section handle is longer than hammer section handle.
