Description
Technical field
The utility model is related to Wrench technical field more particularly to a kind of telescopic spanners.
Background technology
Spanner is during maintenance of equipment for bolt, bolt jointing part to be fastened and unclamped.Spanner usually exists
The one or both ends of shank are formed with the opening or sets of holes of grip bolt or nut, and threadingly direction of rotation applies in shank when use
External force can twist bolt or nut.But in different environment, threaded connector can be influenced to different extents, holds
Easily there is the different phenomenon such as corrosion, corrosion.In this way will be extremely laborious when being dismantled to it, it can also drag sometimes slow
The process entirely repaired.
Utility model content
It the purpose of the utility model is to overcome the deficiencies in the prior art, adapts to reality and needs, a kind of scalable pull is provided
Hand.
In order to realize that the purpose of this utility model, the technical solution adopted in the utility model be：
A kind of telescopic spanner, including front hand grip, fixes sleeve, back handle, handle, before the front hand grip inside is provided with
Handle internal thread hole, fixes sleeve side outer ring are provided with fixes sleeve outside threaded holes, in the fixes sleeve other side
It is provided with fixes sleeve internal thread hole, the handle side is provided with handle outside threaded holes, the front hand grip internal thread hole and institute
The cooperation of fixes sleeve outside threaded holes is stated, the fixes sleeve internal thread hole coordinates with the handle outside threaded holes, the front hand grip,
It is hollowed out in fixes sleeve, handle and is provided with through-hole, the back handle is arranged in the through-hole, and the back handle other side is solid
It is scheduled in handle, is coordinated with handle threaded screw bore by opening fixes sleeve so that back handle is moved forward and backward in through-hole to be made
Tool can stretch.
Described back handle one end is provided with the shaft shoulder, and the shaft shoulder is arranged in the through-hole in front hand grip.
The back handle does not have one end of the shaft shoulder to be provided with jump-ring slot, and the jump-ring slot passes through handle through hole, passes through clamp spring
So that back handle is fixed with handle.
The beneficial effects of the utility model are：
, can be easy to carry the utility model has the beneficial effects that simple in structure, when use, is easy to operate succinct, is suitable for
The fastening and dismounting of the big bolt of pretightning force.

Fig. 5 is hand sectional view.
Wherein, 1 front hand grip, 2 back handles, 3 fixes sleeves, 4 handles, 5 clamp springs, 6 through-holes, 7 front hand grip internal thread holes, 8 are consolidated
Determine internal thread of sleeve hole, 9 fixes sleeve outside threaded holes, 10 shaft shoulders, 11 jump-ring slots, 12 handle outside threaded holes.
Specific implementation mode
The utility model is further illustrated with reference to the accompanying drawings and examples：
Referring to Fig. 1-5.
The utility model discloses a kind of telescopic spanner, including front hand grip 1, fixes sleeve 3, back handle 2, handle 4, institutes
It states 1 inside of front hand grip and is provided with front hand grip internal thread hole 7,3 side outer ring of the fixes sleeve is provided with fixes sleeve external screw thread
Hole 9, fixes sleeve internal thread hole 8 is provided in 3 other side of the fixes sleeve, and 4 side of the handle is provided with the outer spiral shell of handle
Pit 12, the front hand grip internal thread hole 7 and the fixes sleeve outside threaded holes 9 coordinate, the fixes sleeve internal thread hole 8 with
The handle outside threaded holes 12 coordinate, and the front hand grip 1, fixes sleeve 3 hollow out in handle 4 and be provided with through-hole 6, after described
Handle 2 is arranged in the through-hole 6, and 2 other side of the back handle is fixed in handle 4, by opening fixes sleeve 3 and handle
4 threaded screw bores coordinate so that back handle 2 is moved forward and backward in through-hole 6 allows tool to stretch.
2 one end of the back handle is provided with the shaft shoulder 10, and the shaft shoulder is arranged in the through-hole 6 in front hand grip 1.
One end of 2 no shaft shoulder 10 of the back handle is provided with jump-ring slot 11, and the jump-ring slot 11 passes through handle（4）Through-hole
6, by clamp spring so that back handle 2 is fixed with handle 4.
The use principle of the utility model is summarized as follows：
Mobilizable back handle 2 is further added by the handle of spanner, increased back handle 2 can be shunk when usually using
Inside fixed handle, the inside that can be fixed on former handle of increased handle will not occur to increase that handle falls off asks
Topic, when without using handle is increased, which in the state in contraction will not be loosened by the connection of screw thread.
Handle extraction, regulation handle can will be increased by unscrewing fixes sleeve 3 and 4 threaded connection place of handle when needing to increase the arm of force
Length realize the loosening to fastener to reach to the requirement of decreased food.
The above description is only the embodiments of the present invention, and it does not limit the scope of the patent of the present invention, every
Equivalents made based on the specification and figures of the utility model are applied directly or indirectly in relevant technical field,
It is equally included in the patent within the scope of the utility model.
