Abstract

The utility model relates to an iron hammer head fixed structure, one end of a grab handle is connected with the inner part of a hammer head, and the end surface point of the grab handle is axially sunk to form a containing embedded groove; the hammer head fixed structure is composed of a convex tooth nail and a plug nail, wherein the convex tooth nail is axially provided with a through hole, the inner wall of the through hole is provided with an oblique surface, one end of the oblique surface is formed with an entering hole section which is used for being axially extended into by the plug nail, the other end of the oblique surface is formed with an outward opening hole section of which the inner diameter is smaller than the outer diameter of the plug nail, the side surface of the convex tooth nail is surrounded and projected with at least one convex tooth of which the tooth tip is extended towards the direction of the entering hole section, the convex tooth nail axially forms a plurality of notches on the outer wall of the outward opening hole section, and the plug nail is pushed and crowded from the inner part to be tightly combined with the hammer head and the grab handle.

Description

Iron hammer tup fixture construction

The utility model is relevant with iron hammer, refers to a kind of iron hammer tup fixture construction especially.

Iron hammer (as Fig. 1) commonly used, mainly comprise a tup 10, a lever 20 and a tup fixture construction 30, one end of lever 20 is provided with an accommodation space 22, and connect and establish what tup 10, tup fixture construction 30 is made of dull and stereotyped 32 and one a pointed plate 34, and establishes what accommodation space 22, its middle plateform 32 axle sleeves are in accommodation space 22, pointed plate 34 utilizes most advanced and sophisticated place to stretch into accommodation space 22, makes tup fixture construction 30 packing tups 10, with fixed hammer 10 what levers 20.

Because when the iron hammer head knocked, iron hammer must bear centrifugal force, with known iron hammer, in its accommodation space, there is a slit dull and stereotyped and pointed plate joint place, easily causes the disengaging of pointed plate because of centrifugal force, and can't the packing tup, cause pitching of tup, easily cause danger in use.

The purpose of this utility model is that the shortcoming that overcomes the prior art structure provides a kind of iron hammer tup fixture construction.

A kind of iron hammer tup fixture construction, comprise a tup, one lever and a tup fixture construction, lever one termination is established in the what tup, and the what end axially subsides formation one appearance caulking groove, the tup fixture construction is made of a double wedge nail and a plug pin, the double wedge nail axially runs through a through hole, through-hole wall has an inclined-plane, one end forms one and enters the hole section, the other end forms an outer hole section of opening, this outer little what plug pin of hole section internal diameter external diameter of opening, and plug pin axially stretches into and enters the hole section, and carry over the inclined-plane and stretch into outer opening in the section of hole, protruding at least one double wedge is encircled in double wedge nail side, and the double wedge crown extends towards entering hole section direction, and the outer wall that double wedge nail what is opened the hole section outward axially forms several breach.

Fig. 1 is the side sectional view of iron hammer commonly used;

Fig. 2 is the side sectional view of the utility model structure.

Fig. 3 is the side sectional view of double wedge nail of the present utility model.

Further specify embodiment of the present utility model below in conjunction with accompanying drawing.

One tup 40, one lever 50 and a tup fixture construction 60, wherein identical with commonly using iron hammer part is promptly no longer added narration, lever 50 connects to be established in the what tup 40, one end end face middle body of lever 50 is axially subside one and is held caulking groove 52, the tup fixture construction is made of double wedge nail 62 and one plug pin 64, double wedge nail 62 axially runs through a through hole 621, its inwall book office forms an inclined-plane 622, one end on this inclined-plane 622 of through hole 621 whats forms one and enters hole section 623, the other end forms an outer hole section 624 of opening, and should open little what plug pin 64 external diameters of hole section 624 internal diameters outward, double wedge is followed closely 62 sides and is encircled protruding a plurality of double wedge 625, and these double wedge 625 crowns extend towards entering hole section 623 directions, and double wedge is followed closely 62 whats and opened the outer wall of hole section 624 outward and axially break totally four breach 626; Double wedge nail 62 axially embeds and holds in the caulking groove 52, plug pin 64 axially stretches into to enter hole section 623 and carry over inclined-plane 622 and stretches into when opening hole section 624 outward, outer hole section 624 inwalls of opening force each breach 626 external-open, impel double wedge 625 tight embeddings firmly to hold caulking groove 52, for lever 50 packing tups 40; Tup fixture construction 60 and 52 fillings of appearance caulking groove have vibration absorptive material 70, the vibration influence that causes when using iron hammer to reduce.

The utility model has the advantages that simple in structurely, the iron hammer head is able to firmly Be combined with lever, avoid centrifugal force when using to cause iron hammer head to pitch and cause Danger has improved the security of using.

Claims

1. iron hammer tup fixture construction, mainly comprise a tup, one lever and a tup fixture construction, lever one termination is established in the what tup, and the what end axially subsides formation one appearance caulking groove, it is characterized in that the tup fixture construction is made of a double wedge nail and a plug pin, the double wedge nail axially runs through a through hole, through-hole wall has an inclined-plane, one end forms one and enters the hole section, the other end forms an outer hole section of opening, should open the little what plug pin of hole section internal diameter external diameter outward, plug pin axially stretches into and enters the hole section, and carry over the inclined-plane and stretch into outer opening in the section of hole, protruding at least one double wedge is encircled in double wedge nail side, and the double wedge crown extends towards entering hole section direction, and the outer wall that double wedge nail what is opened the hole section outward axially forms several breach.

2. a kind of iron hammer tup fixture construction according to claim 1 is characterized in that the tup fixture construction and holds to clog between caulking groove that vibration absorptive material is arranged.
