Specific embodiment
Below in conjunction with attached drawing, to the utility model, above-mentioned and other technical characteristic and advantage carry out clearly and completely
Description, it is clear that described embodiment is only the section Example rather than whole embodiments of the utility model.
With reference to Fig. 1, a kind of dismountable building drill bit chuck handle is present embodiments provided, including key body 1, the
One extension bar 2 and the second extension bar 3；Key body 1 is extended transversely through by first through hole 4, the first extension bar 2 and the second extension bar 3
First through hole 4 is stretched into from the both sides of first through hole 4 respectively, and is pieced together with key body 1 T-shaped；First extension bar 2 is far from key
The end of body 1 is equipped with the first force section 5, and the second end of the extension bar 3 far from key body 1 is equipped with the second force section 6, the first force
5 and second force section 6 of portion is in flat.
In the present embodiment, due to having the first extension bar 2 and the second extension bar 3, it can be pieced together with key body 1 and be in
It is T-shaped.And it is respectively formed the first force section 5 and the second force section in the end of the end of the first extension bar 2 and the second extension bar 3
6, therefore just compare when exerting a force to extension bar and save labour.Because of the stress point there are two tools when exerting a force to extension bar,
So it opposite can save labour.In fact, artificially going rotation is limited with every 90 degree of corner in fact, there are one can during stress point
90 degree are turned over to rely on this stress point, and is not just worked to next 90 degree of this stress points.Therefore it provides two by
Force practicallys guarantee that extension bar can be relied in all processes of rotation, use.
With reference to Fig. 2, in one embodiment, the first extension bar 2 is equipped with square protruding 7 close to the end of key body 1, and second
Extension bar 3 is equipped with square groove 8 close to the end of key body 1, and the first extension bar 2 and the second extension bar 3 pass through 7 He of square protruding
Square groove 8 is connected in the first through hole 4, and is pieced together with key body 1 T-shaped.
In the present embodiment, the first extension bar 2 and the second extension bar 3 are connected by square groove 8 and square protruding 7.
Here, square groove 8 and square protruding 7 are interference fitted, and can be connected the first extension bar 2 and the second extension bar 3 by squeezing.
The first extension bar 2 and the second extension bar 3 can be detached by directly extracting.Here, square groove 8 and square protruding 7 can also be
Magnetic connection, the mode used is similar with interference fit, does not repeat herein.It can be pieced together after connection with key body 1 in T
Type, this structure is similar to spanner, therefore just compares when exerting a force to extension bar and save labour.In another embodiment, may be used
With respectively in the end of the first extension bar 2 and the end set internal thread and external screw thread of the second extension bar 3, so as to by the first reinforcing
2 and second extension bar 3 of bar connects.
With reference to Fig. 2, in one embodiment, the first force section 5 is equipped with the first via 9.First force section 5 is equipped with anti-
The length direction of sliding line, the ridge orientation of anti-skid chequer and the first extension bar 2 is vertical.It in the present embodiment, can by the first via 9
The first force section 5 is fixed on power drill, the first extension bar 2 is tied on power drill by rope here.Also,
Friction when exerting a force to the first extension bar 2 can be provided by anti-skid chequer, because of the direction and the of the first extension bar 2 of rotation
The length direction of one extension bar 2 is coplanar, so when the ridge orientation of anti-skid chequer and the vertical length direction of the first extension bar 2,
Also it is vertical with the direction of the first extension bar 2 of rotation.So it is also big painstakingly when rotating the first extension bar 2, convenient for rotation.
Correspondingly, in one embodiment, the second force section 6 is equipped with the second via 10.Second force section 6 is equipped with anti-
The length direction of sliding line, the ridge orientation of anti-skid chequer and the second extension bar 3 is vertical.In the present embodiment, pass through the second via 10
Second force section 6 can be fixed on power drill, here be tied the second extension bar 3 on power drill by rope.And
And friction when exerting a force to the second extension bar 3 can be provided by anti-skid chequer, because of the direction of the second extension bar 3 of rotation
It is coplanar with the length direction of the second extension bar 3, so when the ridge orientation of anti-skid chequer and the length direction of the second extension bar 3 are vertical
When, it is also vertical with the direction of the second extension bar 3 of rotation.So it is also big painstakingly when rotating the second extension bar 3, convenient for rotation.
Fig. 1 is referred again to, in one embodiment, the end of key body 1 is equipped with cone tooth 11, and the end of cone tooth 11 is equipped with positioning
Pin 12, and key body 1, cone tooth 11 and positioning pin 12 are coaxially disposed.
In the present embodiment, key body 1, cone tooth 11 and positioning pin 12 are coaxially disposed, help to fasten and unclamp brill
Drill bit on collet.Because three is coaxial, stress is concentrated and is not disperseed.
Particular embodiments described above has carried out into one the purpose of this utility model, technical solution and advantageous effect
The detailed description of step, it should be understood that the foregoing is merely specific embodiment of the utility model, are not used to limit this reality
With novel protection domain.Particularly point out, to those skilled in the art, it is all the spirit and principles of the utility model it
Any modification, equivalent substitution, improvement and etc. that are interior, being done, should be included within the scope of protection of this utility model.
