Abstract

The utility model relates to an improved changing structure for a hammer head. A hammer body is fixed on the top of a grab handle, and the body is a hollow cylinder. Hammer fixed seats which are hollow seat body are respectively embedded at the both ends. A U-shaped shrapnel can be installed. Plane surfaces are arranged on the top and bottom both side ends of the seat body, and a circular hole is pasted at the central position. Circular holes which are respectively penetrated through a position gun by an introversion 21 are arranged at the both sides of the bottom of the base. A blocking convex loop which is at the side end is stopped at the U-shaped shrapnel. A position convex pole is arranged at the both ends of the side of the top. A knocking element is fixed by a telescopic card, and the knocking element can be the hammer, a claw hammer, etc. One layer of rubbery material is covered at the outer layer of a hammer fixed seat and the grab handle hammer body, and the toughness and the strength can be increased. The structure can assemble the knocking elements everywhere, and the loading and unloading are simple.

Description

The tup displacement structure of improvement

The utility model relates to a kind of tup displacement structure of improvement, belongs to the technical field of hand-operated tools.

The tup that knocks of existing hammer is all made one with body, because the working substance different in kind, the user must carry various hammers, but hammer body heaviness is carried true feeling inconvenience, and serious amount influences operating efficiency.So have tup and body to adopt the fixing structure of screw, but effort is screwed when still costing during displacement, otherwise be easy to loosening slippage when knocking, it is poor slightly to use.

The purpose of this utility model be to provide a kind of improvement tup displacement structure it can overcome above-mentioned shortcoming, utilize by press button and control the flexible of U-shaped shell fragment and positioning convex column, can replace variform knocking component, can increase work efficiency.

The purpose of this utility model is achieved in that the tup displacement structure of improvement, and a hammer body 20 is fixed on lever handle 10 tops, and this body is a hollow Cylinder, each setting-in one tup holder 20 of both end sides; Hammer should holder 30 be hollow form pedestals, the U-shaped shell fragment 40 of can packing into, the symmetrical position of two side ends is scabbled face 31,33 its middle positions respectively and is drilled with hole, a garden 32,34 about holder 30 pedestals, this hole, monosymmetric garden, pedestal bottom 32 outwards wears a pilot pin 41 by dividing respectively, its side ring is established a retaining bulge loop 412, but two ends, U-shaped shell fragment 40 top extend disymmetrical positioning convex column 44, can with U-shaped shell fragment 40 push and sliding extension in the hole, garden 34 of this pedestal upper end symmetry, the knocking component that the scalable fixing of the positioning convex column of symmetry 44 one is to be replaced.Nail pulling tup 65 or axe etc.Lever 10, hammer body 20, tup holder 30 outer cladding one deck elastomeric materials.The shelves bulge loop is connected with the projection 411 of a semicircular in shape, pulls in the hole, garden 42 of U-shaped shell fragment in the setting-in top.

Now in conjunction with the accompanying drawings the structure of the tup displacement structure of improvement is described in detail.

By Fig. 1, a hammer body 20 is fixed on lever 10 tops; Body 20 is hollow Cylinders, the holder 30 of each setting-in one tup of both end sides, replaceable difform knocking component, for example tup 60, nail pulling tup 65, or knocking component such as axe, at lever 10, the skin of hammer body 20 and tup holder 30 coats one deck elastomeric material die cast again.

Fig. 2,3, the chimeric tup holder 30 of fixing in hammer body 20 tops, this holder 30 is a hollow form pedestal, the U-shaped shell fragment 40 of can packing into, scabble face 31 respectively in the symmetrical position of two side ends up and down at holder 30 pedestals, 33, this plane 31,33 middle positions are drilled with hole, a garden 32 respectively, 34, this hole, monosymmetric garden, pedestal bottom 32, wear a pilot pin 41 respectively from inside to outside, its side ring is established a retaining bulge loop 412, and the retaining bulge loop is established a projection 411 that is half garden shape, can utilize retaining bulge loop 412 tops to pull in the inwall in this hole, garden, pedestal bottom side 32, be provided with projection 411 at pilot pin 41 sides, pulling in the hole, garden 42 of U-shaped shell fragment in the setting-in top, makes symmetrical pilot pin 41, structure with U-shaped shell fragment 40 formation interlocks.

Two ends, U-shaped shell fragment 40 top side extend disymmetrical positioning convex column 44, can with U-shaped shell fragment 40 push and sliding extension in the hole, garden 34 of this pedestal upper end symmetry, and the scalable fixing of the positioning convex column 44 of symmetry one to be replaced knock the tup element, but press button 413 is pressed in the outside of pilot pin 41 also setting-in, so that the usefulness that finger is pushed simultaneously can be strengthened its integral intensity and toughness as for outer field elastomeric material clad 50.By Fig. 4,5, when the user is used to point the button 413 of depressing the left and right sides simultaneously, just U dish shell fragment 40 compressions of U-shaped elasticity 4a owing to pull in pilot pin 41 tops, make in two positioning convex column, the 44 complete retraction tup holders 30 of top side, and the locating hole 61 of disengaging tup 60, so can take out or replace the knocking component of different shape.

When the user discharges when press press button 413, U-shaped shell fragment 40 can be ejected the positioning convex column 44 on its top by its elastic restoring force, and positioning convex column 44 can stretch into tup 60, and draw in 61 interior corresponding location, tup 60 and hammer body 20 can be fixed be integral.

Compared with prior art, the changing structure for hammer head of improvement has following advantages:

1, can by need of work, replace rapidly variform knocking component

2, this structure guarantees that loosening slippage situation can not take place knocking component

3, easy to carry
