Abstract
The utility model discloses a retractable wrench, including wrench body, wrench body is including keeping silent and the handle, the handle includes and keeps silent the telescopic link of structure as an organic whole and the sleeve that the telescopic link outer wall was located to the cover, set up at least one through -hole along telescopic axle arrangement on the telescopic lateral wall, be equipped with the screw that corresponds with the position of through -hole on the telescopic link, wear to be equipped with the bolt in at least one through -hole, the bolt runs through the through -hole and extends to the screw position. The utility model discloses the length that can adjust the spanner according to the work occasion needs of difference during the regulation, only needs to adjust telescopic link and telescopic relative position for the screw of before mutually supporting is corresponding with other through -hole and screw respectively with the through -hole, after reaching required position, penetrates the bolt through -hole and extends to the screw again, and tighten the bolts can. The utility model is simple in operation, convenient to use.
Description
Technical field
The utility model belongs to handware production technical field, is specifically related to a kind of telescopic spanner.
Background technology
Spanner is a kind of conventional installation and removal instrument, usually with carbon structural steels or alloy structure steel making.Spanner utilizes lever principle to twist bolt, screw, nut and other screw threads and tightly holds the opening of bolt or nut or the hand tools of trepanning firmware.Spanner is shaped with opening or the trepanning of grip bolt or nut usually in the one or both ends of shank, during use, threadingly direction of rotation applies external force at shank, just can twist bolt or nut.
When installing in the processing of different workplaces or dismantle securing member, some needs is dark or shallow by the position at the securing member place of twisting, even some is too concealed, because of apart from too far away or operating space is narrow and small and it is too late to make operator stretch out one's hand, and the length of existing spanner is general all unadjustable, therefore need ceaselessly to change spanner different in size in different workplaces, this mode not only makes work more loaded down with trivial details, and carries very inconvenient.
Utility model content
The utility model provides a kind of telescopic spanner, according to different workplace needs, can regulate the length of spanner.
The technical solution of the utility model is: a kind of telescopic spanner, comprise wrench body, described wrench body comprises jaw and handle, described handle comprises the expansion link be structure as a whole with jaw and the sleeve being sheathed on expansion link outer wall, the sidewall of described sleeve offers at least one axial arranged through hole along sleeve, described expansion link is provided with the screw corresponding with the position of through hole, bolt is equipped with, described bolt-through through hole and extend to screw position at least one through hole.
When needing the length regulating spanner, the disassembling bolts being fixedly connected with sleeve and expansion link will be used for, then the relative position of adjustable telescopic rod and sleeve, the screw cooperatively interacted before making and through hole respectively with other through hole and screw corresponding, after reaching desired location, again bolt penetrated through hole and extend to screw, tighting a bolt.
In order to prevent spanner from going out from slippage on hand, as preferably, described sleeve outer wall is provided with leather skid resistant course.
As preferably, described sleeve outer wall is provided with grabs the depression of taking for hand.
As preferably, described sleeve outer wall is provided with the decorative pattern in irregular arrangement.
As preferably, the diameter of described sleeve reduces from the one end away from expansion link gradually towards one end of expansion link.
Compared with prior art, the beneficial effects of the utility model are embodied in:
The utility model can need the length regulating spanner according to different workplaces, during adjustment, only need the relative position of adjustable telescopic rod and sleeve, the screw cooperatively interacted before making and through hole respectively with other through hole and screw corresponding, after reaching desired location, bolt penetrated through hole and extends to screw, tighting a bolt.The utility model is simple to operate, easy to use.

Detailed description of the invention
As shown in Figure 1, the utility model comprises wrench body, wrench body comprises jaw 1 and handle 2, handle 2 comprises the expansion link 21 be structure as a whole with jaw 1 and the sleeve 22 being sheathed on expansion link 21 outer wall, the sidewall of sleeve 22 offers at least one axial arranged through hole 221 along sleeve 22, expansion link 21 is provided with the screw 211 corresponding with the position of through hole 221, is equipped with bolt 3 at least one through hole 221, and bolt 3 runs through through hole 221 and extends to screw 211 position.
When needing the length regulating spanner, remove being used for being fixedly connected with sleeve 22 with the bolt 3 of expansion link 21, then the relative position of adjustable telescopic rod 21 and sleeve 22, the screw 211 cooperatively interacted before making and through hole 221 respectively with other through hole 221 and screw 211 corresponding, after reaching desired location, again bolt 3 penetrated through hole 221 and extend to screw 211, tighting a bolt 3.
In order to prevent spanner from going out from slippage on hand, the slip-proof way in the utility model can have multiple, such as, be provided with leather skid resistant course at sleeve 22 outer wall; Sleeve 22 outer wall is provided with grabs the depression 223 of taking for hand, sees Fig. 3; Sleeve 22 outer wall is provided with the decorative pattern 222 in irregular arrangement, sees Fig. 4; The diameter of sleeve 22 reduces from the one end away from expansion link 21 gradually towards one end of expansion link 21, sees Fig. 5.
