Abstract
The utility disclose a multi-purpose quick solid wrench, including a wrench body and a bayonet. A slide block is arranged at one side inside the bayonet of the solid wrench. The moving direction of the slide block and the central line of the bayonet form a certain angle. The bayonet width of the utility model is changed because of the existence of the slide block, and the bayonet width becomes a changeable number, so the bayonet can lock all multi-arris faces, the sizes of which are between the maximum and the minimum. One wrench is applicable to assemble and dissemble various specifications of bolts and nuts.
Description
Technical field
The utility model relates to a kind of instrument, refers in particular to a kind of fork spanner that multiple edge bodies such as bolt, nut are used that loads and unloads.
Background technology
The fork spanner of permanent opening is the instrument that often uses in flight-line maintenance, when installing, it have small and exquisite, screens is accurate, characteristics such as simple to operate, when parts such as loading and unloading bolt, nut, is the instrument of people's first-selection.This fork spanner respectively has an opening at two ends, the nut of corresponding certain specification or the width of bolt are 17 millimeters as an opening size, and the other end opening is 18 millimeters or 19 millimeters.That is to say that the opening of stiff spanner is fixed, one can only dismantle the bolt or the nut of two sizes to spanner.And after in use whenever rotating to an angle, the opening of spanner need be withdrawn into beyond six aspects of screens, rotation is backward blocked another to six aspects then, could rotate nut or bolt once more like this.If seeing the place operation of road bolt not or nut, can only work gropingly with sensation, efficient is lower.
Summary of the invention:
The utility model technical issues that need to address provide the quick-action solid wrench of using of a kind of bolt that can twist a plurality of specifications or nut more
The utility model is achieved in that
The utility model comprises wrench body and conventional bayonet socket, in the wrench body of the side in the bayonet socket of fork spanner a slide block is set.
Further improvement of the utility model is: the moving direction of slide block becomes 0-60 degree angle with the center line of bayonet socket, so that slide block makes the reduced width of bayonet socket when stretching out.
Further concrete structure of the present utility model is: be shaped on a blind hole of depositing slide block in place, the side of spanner bayonet socket, the wrench body head, on the plane of wrench body head, be drilled with locating hole, locating hole communicates with above-mentioned blind hole, and orthogonal, be provided with one in it and limit the limited bolt of slide block shift position; One chute corresponding with above-mentioned limited bolt is set above the slide block, the cross sectional shape of the size of slide block and a back part thereof is corresponding with the blind hole of wrench body head, the one side of slip front is a circular arc, the rear portion end face of slide block is provided with blind hole, is provided with spring in blind hole, between the blind hole of slide block and wrench body.
The technological progress that the utility model is obtained is:
The utility model is because the existence of slide block, changed the width of bayonet socket, the width of bayonet socket is changed along with moving of slide block, therefore a bayonet socket just can be used to load and unload two kinds or two or more nut or bolts, and one can be used for the bolt of plurality of specifications, the loading and unloading of nut to spanner.
Therefore can reduce the quantity that service worker is carried instrument, alleviate working strength of workers.
The utility model is not when using, slide block is under the effect of spring, some stretches out the card face of bayonet socket, when needs are twisted with the bolt of bayonet socket same size or nut, slide block is pushed in the blind hole of getting back in the wrench body, and spanner can normally load and unload bolt, the nut that has corresponding size with the bayonet socket fixed width.When the less bolt and nut of needs loading and unloading size, because slide block reaches the outside of bayonet socket face, the bayonet socket face of slide block and opposite side can block six sides of bolt, nut, when pulling, slide block is subjected to the pressure vertical with glide direction, be that slide block can not slide, can be on six sides afterburning, thus tighten or unclamp nut; When the backward rotation spanner, this moment, slide block was to be subjected to inside thrust, and slide block unclamps, can be easily to the counter-rotation spanner, thus carry out afterburning next time.And will not extract out from bolt or nut by the spanner bayonet socket,, can easily use yet even bolt, nut are in the place that can't see.
Because the moving direction of slide block of the present utility model and the bayonet socket of spanner have certain angle, this angle generally is about 20 °, when slide block is in different positions, the bayonet socket size difference of spanner, after slide block is fully retracted wrench body, bayonet socket width maximum, when slide block reaches outermost, the bayonet socket minimum so the utility model can block many faceted pebbles of all sizes of boundary between minimum and maximum, is applicable to bolt, the nut of all specifications of loading and unloading circle between minimum and maximum bayonet socket.
Limited bolt on the wrench body and the chute on the slide block can limit the amount of movement of slide block, and slide block is moved in suitable scope.
Description of drawings:
Fig. 1 is the partial structurtes generalized section of Wrench head of the present utility model.
Wherein: 1, wrench body, 2, the blind hole in the wrench body, 3, spring, 4, the spring eye in the slide block, 5, limited bolt, 6, chute, 7, slide block, 8, bayonet socket.
The specific embodiment:
Below in conjunction with accompanying drawing the utility model is described in further details:
The utility model is in the wrench body 1 at bayonet socket 8 places of the dead mouth spanner of routine a slide block 7 to be set.
In the driving end of the wrench body 3 at the upper side place of spanner bayonet socket 8, system one is deposited the blind hole 2 of slide block 7, and the center line of two bayonet socket faces of the center line of this blind hole 2 and spanner bayonet socket 8 is into about 20 ° angle; Bore a locating hole on the plane of the driving end of wrench body 1, this locating hole communicates with blind hole 2, and orthogonal; The limited bolt 5 of one restriction slide block, 7 sliding positions is set in the locating hole; The size of slide block and shape are corresponding with blind hole 2, and a chute 6 is set above the slide block 7, and chute 6 is corresponding with the position of the limited bolt 5 of assembly wrench body head; Slide block 7 front ends are circular arc, and the rear portion end face is provided with blind hole, and this blind hole is provided with the spring 3 that slide block 7 is ejected for placing the spring eye 4 of spring in it.
