Description
Technical field
The present invention relates to a kind of small tool, in particular to a kind of fitter's hammer that can replace various different striking heads belongs to
In the technical field of small tool.
Background technique
When pincers worker repair operation, especially when some soft components carry out pincers worker repair operation, it is often necessary to make
With the percussion hammer of copper rod and different shape, unlike material.Some softer percussion hammers are such as deformed after copper rod is used for a long time
Abrasion, length is shorter and shorter, and weight is also increasingly lighter, and beating effect will be remarkably decreased at this time, until copper rod is depleted to it
Length is less than hand-held length and can not continue to use.Pincers worker needs to carry more than one piece according to different actions when repair operation
The percussion of different shape and unlike material is hammered into shape, brings inconvenience to work such as mechanical erection, maintenances of equipment.
Summary of the invention
The object of the present invention is to provide a kind of structures, and simple, easy to carry, tup both ends can replace the pincers of striking head respectively
Work combination taps hammer.
The present invention is achieved by the following technical programs:
A kind of pincers worker combination hammer, including hammer body, handle, gland and several striking heads, hammer body are cylindrical body, hammer body middle part and hand
Handle one end is vertically fixedly connected by screw thread；Hammer body both ends end face center is respectively equipped with taper hole, and hammer body both ends outer peripheral surface is set respectively
There is external screw thread；The head shape of striking head is different, and the tail portion of striking head is cone table, the taper hole of the cone table and hammer body
Matching；The head lower end of striking head and the junction of tail portion upper end extend radially outward a clamp ring；Gland one end is equipped with through-hole, institute
The aperture d for stating through-hole is less than clamp ring outer diameter D, is greater than striking head head lower end diameter D1；The cone of different shape percussion head-tail
Stage body is pressed into hammer body respectively and corresponds in the taper hole of one end, and gland internal screw thread is tightened on the external screw thread of hammer body end, makes different strike
It taps the head and is separately fixed on hammer body both ends.
The purpose of the present invention can also be further realized by following technical measures.
Further, the taper of the cone table of the taper hole at hammer body both ends and percussion head-tail is 1:8~1:12.
Further, radial slot is respectively equipped on the end face of hammer body both ends.
Further, there are gap deltas between the bottom inside face of gland and the annular surface of adjacent clamp ring.
Further, the handle other end is cased with antiskid glue sleeve.
Further, the material of hammer body and gland is by the Fine Steel Casting iron of Tempering and Quenching, the material of the handle
Matter is aluminium alloy.
Further, the shape of striking head is column or round end shape or spade or cusp-shaped, and the material of striking head is steel
Copper or wooden or rubber mass or nylon matter.
It is the configuration of the present invention is simple, compact, easy to carry, easily operated, in use, the need that can be installed according to part
It wants, the striking head of quick-replaceable applicable different shape and material, to meet the part installation requirements of various materials, shape.Copper
The volume and weight of matter striking head is much smaller than copper rod, has saved expensive copper material, has been not in the inadequate phenomenon of hand-held length.?
After striking head needed for having selected assembly, the cone table that only need to first will hit against head-tail is pressed into the taper hole that hammer body corresponds to one end respectively
In, then the gland that will hit against on head is tightened on one end of hammer body, and striking head, gland and striking head is made to be firmly attached into one
Body positions by taper hole and bears the impact force of percussion process.Copper striking head of the invention, nylon striking head, rubber tap
Head and wooden striking head etc. can repeat replacement and use, when being tapped instead of copper rod, the impact efficiency hit using hand hammer
Fruit, maximization improve percussion power.
The advantages and features of the present invention will be illustrated and explained by the non-limitative illustration of preferred embodiment below,
These embodiments only provide as an example referring to attached drawing.
Detailed description of the invention
Fig. 1 is structure chart of the invention；
Fig. 2 is the shape of three kinds of striking heads；
Fig. 3 is the A-A cross-sectional view of Fig. 1.
Specific embodiment
Present invention will be further explained below with reference to the attached drawings and examples.
As shown in Figure 1, the present invention includes hammer body 1, handle 2, gland 3 and several striking heads 4, hammer body 1 is cylindrical body, hammer
1 middle part of body is fixedly connected with 2 one end of handle by the way that screw thread is vertical.1 both ends end face center of hammer body is respectively equipped with taper hole 11, hammer body 1
Both ends outer peripheral surface is respectively equipped with external screw thread 12.The material of hammer body 1 and gland 3 be by the Fine Steel Casting iron of Tempering and Quenching,
The Fine Steel Casting iron trade mark that the present embodiment uses is 45# steel.
It is cylindric (A) round end shape (B) and coniform as shown in Fig. 2, the head shape of striking head 4 is different
Or the spade that does not indicate of such as Fig. 2 or cusp-shaped other shapes that can be used to tap (C),.Its material be steel or it is copper or
Wooden or rubber or nylon.
The tail portion of striking head 4 is cone table 41, and cone table 41 is matched with the taper hole 11 of hammer body 1.The cone table 41 of striking head 4
It injects in the taper hole 11 of hammer body 1, by gland 3 striking head 4 is linked into an integrated entity with hammer body 1.
The head lower end of striking head 4 and the junction of tail portion upper end extend radially outward a clamp ring 42.3 one end of gland is equipped with
The aperture d of through-hole 31, the through-hole 31 is less than clamp ring outer diameter D, is greater than 4 head lower end diameter D1 of striking head, thus to gland 3
Play position-limiting action.The cone table 41 of 4 tail portion of different shape striking head is pressed into respectively in the taper hole 11 of the corresponding one end of hammer body 1, pressure
3 internal screw thread of lid is tightened on 1 end external screw thread of hammer body, is separately fixed at different striking heads 4 on 1 both ends of hammer body.
The taper of the cone table 41 of 4 tail portion of taper hole 11 and striking head at 1 both ends of hammer body is 1:8~1:12, hammer body 1 and is struck
It taps the head and 4 positions and be fixedly connected by taper hole 11, bear the impact force of percussion process, replacement striking head 4 is faster.
2 other end of handle is cased with antiskid glue sleeve 21, can also buffer percussion during percussion while playing anti-slip effect
Power.
As shown in figures 1 and 3, radial slot 13, replacement striking head 4 easy to disassemble are respectively equipped on 1 both ends end face of hammer body.Pressure
There are gap delta between the bottom inside face of lid 3 and the annular surface of adjacent clamp ring 42, striking head during tapping can be prevented
4 get rid of winged and hurt sb.'s feelings, and are not subject to the impact force tapped.3 outer knurled of gland processing, when replacing striking head 4, convenient for unscrewing or twisting
Gland 3.
In addition to the implementation, the present invention can also have other embodiments, all to use equivalent substitution or equivalent transformation shape
At technical solution, be all fallen within the protection domain of application claims.
