A kind of telescopic hammer for building
Technical field
This utility model belongs to building and uses technical field of tools, especially relates to a kind of stretching for building
Contracting formula hammer.
Background technology
At present, the building hammer function commercially used is more single, can be only done and nails, beats
And pull out a nail.According to mechanics principle, in order to easy to use and laborsaving, it is longer that we always want to hammer handle,
But sometimes, owing to using limited space, we wish that again hammer handle can be shorter, and we are normal
The hammer seen is all the hammer handle of regular length, uses very inconvenient;Existing building hammer is substantially
The most do not add other functional structure, when building work high above the ground, it is sometimes desirable to carry out tightening or loosening spiral shell
Silk nail, then need to carry screwdriver specially and operate;And carpenter is setting up pillar and clamping fastener nut
Time, need simultaneously with the instrument such as hammer and spanner, carry inconvenience, also easily lose in the course of the work
Fall or lose, greatly reducing work efficiency, therefore being improved.
Summary of the invention
The purpose of this utility model is the deficiency existed for above-mentioned prior art, it is provided that one is used for building
Telescopic hammer, it have can the length of telescopic adjustment hammer handle, built-in screwdriver and elasticity bolt or
The feature of nut.
In order to realize above-mentioned purpose, this utility model be the technical scheme is that a kind of for building
Telescopic hammer, including tup and hammer handle, described tup is arranged on the end of hammer handle;Described tup
One end is provided with hammer cap, and the other end of described tup is provided with nail puller;The top of described tup offers nut
Groove;Described hammer handle includes fixing pipe and expansion link, and described expansion link is inserted in fixing pipe, described fixing
The sidepiece of pipe is provided with the fastening bolt of locking expansion link;The inside of described expansion link is provided with inner chamber, described
Inner chamber saving has screwdriver, and described screwdriver is provided with external screw thread, and the inner chamber of described expansion link is provided with
Female thread with external thread bolt connection.
It is provided with on described nail puller " V " type groove.
The outer surface of described expansion link afterbody is coated with Anti-slip cover.
After using said structure, compared to the prior art this utility model has the advantage, that this practicality is new
Type simple in construction, offers nut groove at the top of tup, has the function of tightening nut or bolt, nothing
Need to carry special instrument to operate, it is the most convenient to use;Slided in fixing pipe tune by expansion link
The length of the required hammer handle of joint, and utilize fastening bolt to be fixed, to reach free telescopic adjustment hammer handle
Length;The inner chamber saving of expansion link has screwdriver, when work high above the ground, owing to having hammer and spiral shell simultaneously
The function of silk cutter, during use, not only facilitates but also will not heave around.
