Abstract

A claw hammer comprises a hammer body, a driver, a grip handle, a telescopic branch force rod and a push handle, wherein the driver is attached to the upper end of the hammer body, the inner part of the grip handle is of a hollow structure, and a push handle clamp opening is formed in the grip handle; the telescopic branch force rod penetrates through and extends into the grip handle from a through hole in the hammer body, the push handle is arranged on the telescopic branch force rod, and the push handle extends out of the grip handle from the push handle clamp opening; and the hammer body and the grip handle are oppositely fixed.

Description

A kind of nail hammer

Technical field:

The present invention relates generally to a kind of hammer, wherein, relates generally to a kind of nail hammer, and this hammer is mainly used in pulling out a nail.

Background technology:

At present, the nail hammer sold of hard ware store generally can rise and be no more than 3 centimetres iron nail.Rise when having surpassed 3 centimetres iron nail, need be below hammer body the cushion block wooden unit, could successfully pull out long iron nail like this.Therefore, the structure of the existing nail hammer of necessary change allows it can pull out short different iron nail rapidly.

Summary of the invention:

According to the existing defective of traditional nail hammer, we have provided a kind of nail hammer, and this hammer can be so that the fulcrum of tup extends in the nail pulling process, thereby makes hammer body near the ailhead position, can be smoothly extract exposing outside the above nail of 3cm.

Described a kind of nail hammer technical scheme is as follows:

It is made up of hammer body, bottle opener, hand grip end, flexible bearing pressure bar and handle; Bottle opener is attached to the hammer body upper end, and hand grip end inside is hollow-core construction, offers the handle bayonet socket on it; Flexible bearing pressure bar passes from the through hole of hammer body and extends to hand grip end inside, and flexible bearing pressure bar is provided with handle, and handle extends hand grip end outside from the handle bayonet socket, wherein, and hammer body and hand grip end relative fixed, by certain way in succession.

Preferably, described hand grip end and dop are connected, and wherein, hand grip end overall diameter is greater than the dop overall diameter.

Preferably, described dop pass the bayonet socket of a word bayonet socket on the hammer body poor revolve to turn 90 degrees be stuck on a word bayonet socket fixing poor.

Preferably, this invention is provided with spring, and the dop outside that it is attached to hand grip end front end is in compressive state.

Preferably, this invention is provided with elongated spring, and the one head fastens the tail end of flexible bearing pressure bar, and the other end fastens hand grip end rear end, is in extended state.

Preferably, described handle bayonet socket is that the distance between the opening is 1～4cm at a plurality of openings that are connected of hand grip end excision.

Preferably, described handle and flexible bearing pressure bar are connected by screw, and it is a projection on the flexible bearing pressure bar, and its length is greater than hand grip end radius, and its diameter is less than the opening diameter of handle bayonet socket.

Preferably, described handle is by the handle bayonet socket flank of tooth grip end outside that reaches.

" a kind of nail hammer " of invention can play 1-15 centimetre iron nail.This invention is simple to operate, nail nipping flexibly and fast, laborsaving saving time, be worthy of popularization.

Description of drawings:

Fig. 1 is a kind of stereogram of nail hammer;

Fig. 2 is the flexible bearing pressure bar dependency structure view in a kind of nail hammer;

Fig. 3 is a kind of in-line bayonet socket view of nail hammer;

Wherein, the 1st, flexible bearing pressure bar, the 2nd, bottle opener, the 3rd, spring, the 4th, hand grip end, the 5th, elongated spring, the 6th, handle bayonet socket, the 7th, handle, the 8th, hammer body, the 9th, dop, the 10th, the holddown groove of in-line bayonet socket, the 11st, the bayonet slot of in-line bayonet socket.

The specific embodiment:

Described a kind of nail hammer technical scheme is as follows:

It is made up of hammer body, bottle opener, hand grip end, flexible bearing pressure bar and handle; Bottle opener is attached to the hammer body upper end, and hand grip end inside is hollow-core construction, offers the handle bayonet socket on it; Flexible bearing pressure bar passes from the through hole of hammer body and extends to hand grip end inside, and flexible bearing pressure bar is provided with handle, and handle extends hand grip end outside from the handle bayonet socket, and wherein, hammer body is fixedlyed connected with the hand grip end.

Preferably, described handle bayonet socket is that the distance between the opening is 2cm at a plurality of openings that are connected of hand grip end excision.

Preferably, described handle and flexible bearing pressure bar are connected, and it is a projection on the flexible bearing pressure bar, and its length is greater than hand grip end radius, and its diameter is less than the opening diameter of handle bayonet socket.

The nail hammer that designs by this mode, the adjustable height of its tup makes to be attached to bottle opener on the hammer body near ailhead, extends the stressed fulcrum of hammer body to the distance of ailhead force position, the shift length of hand grip end gets a promotion, so the shift length of ailhead stress point gets a promotion.
