Abstract

The utility model discloses an abnormal claw hammer, and aims to a technical proposal of a claw hammer with a simple structure, convenience and high efficiency. The abnormal claw hammer comprises a hammer handle and a hammer body; the top surface of the hammer is provided with a packing block in a similar triangular shape; the outward surface of the packing block is in an arc shape; the camber line is matched with the upturned arc-shaped surface of the hook tip of an original hammer; and the surface of the packing block towards the hammer surface is a section shorter than the hammer surface. Therefore, the supporting point of the hammer can be lifted correspondingly during the operation, thereby saving the force for pulling out the nail and preventing the nail from being bent. The utility model is applicable to the concentrated out-pulling of a large number of nails.

Description

The abnormity claw hammer

Technical field

The utility model belongs to the carpenter field, specifically is meant claw hammer.

Background technology

Hammer is the important apparatus of woodworking, and wherein a kind of hammer that can draw out a nail is commonly called as claw hammer, and an end of side-looking hour hammer body is the bill shape and this end jag processing is tripped out nail so that block the head of a nail, and the other end generally is the rounded flat side of a hammer, can be used to impact; Approximate one and hammer into shape of the end face of hammer vertical face, then be the arcuation that upwarps near the bill place, this kind hammer can be brought into play good effect in general non-professional use, and the woodworking that relates under construction usually has a large amount of timber to use as the auxiliary material of construction, this kind material often need trip out nail, amount is big and tight, general this claw hammer has the following disadvantages in concrete use operation: when nail just begins to trip out still easily efficiently, but for the long nail of the bar of large size, desire further continues to trip out then very difficult, main cause is that the fulcrum that trips out the head of a nail and hammer along with nail is that the discrepancy in elevation of contact point of peen face and timber face is increasing, so just make that the axial angle of the direction of the power that trips out nail on the hammer and nail is also increasing, naturally be that the gas work efficiency of requiring great effort very much is also low, also degree of limpening was very big and be unfavorable for re-using when nail tripped out, and was difficult to satisfy convenient requirement efficiently.

Summary of the invention

The purpose of this utility model just provides a kind of new technical scheme of claw hammer, and it can eliminate above-mentioned deficiency effectively.

The technical program is achieved in that the cushion block that is approximate triangular shape at the peen face affixed of claw hammer, the one side outwardly of cushion block is circular-arc, the arcuation face that the bill place of camber line and former hammer upwarps matches, and it is a bit of that the end towards the flat side of a hammer on the cushion block then is shorter than flat side of a hammer place.

The design's beneficial effect is to improve work efficiency, has significantly reduced the phenomenon that the nail that trips out buckles.

Description of drawings

Fig. 1 is usual claw hammer and the mode of operation view thereof that uses.

Claw hammer and mode of operation view thereof that Fig. 2 gives an example for the design.

Among each figure, 1 is the hammer handle, and 2 are the hammer body, and 3 is the peen face, and 4 is the flat side of a hammer, and 5 is timber, and 6 is nail, and 7,8 are respectively the axis of nail, the direction of the power that trips out nail on the hammer, and 9 is cushion block.

The specific embodiment

As shown in Figure 1, after nail 6 is tripped out certain length, hammer is 1 and hammer the transformation that angle has all taken place body 2 into shape, steeved by high in the position of the point that contacts with the head of a nail on the hammer, tie point with the peen face 3 and the flat side of a hammer 4 is the direction of hammer body continuation further change power 8 of meeting under the drive of the hammer handle of turning right of fulcrum, further axial 7 of increasing and nail angle is understood the stretch bending nail naturally, also makes the difficulty more that trips out of nail; As shown in Figure 2, a cushion block 9 that is nearly triangular shape in the processing that matches with the goat's horn extrados on the end face 3 of hammer, cushion block 9 can be the solid material of a monoblock, also can be hollow, it is a bit of that the end towards the flat side of a hammer on the cushion block then is shorter than flat side of a hammer place, as can be seen from Figure 2, is that fulcrum is when rotating at hammer driving the extrados of hammer body with cushion block, trip out raising of the head of a nail along with nail, the cushion block that is triangular shape also can be gradually with former hammer body bed hedgehopping gradually, reduced the vertical angle in the horizontal direction of hammer body, make the point that blocks the head of a nail on the hammer to work a direction of exerting oneself be vertical direction near the axis direction of nail all the time, avoid the undue bending of nail, made also that to trip out nail laborsaving many, improved work efficiency.

Claims (1)

1, a kind of special-shaped claw hammer, form by hammer handle, hammer body, it is characterized in that device has one to be the cushion block that is similar to triangular shape on the peen face of hammer, the one side outwardly of cushion block is circular-arc, the arcuation face that the bill place of camber line and former hammer upwarps matches, and it is a bit of that the end towards the flat side of a hammer on the cushion block then is shorter than flat side of a hammer place.
