Abstract
The invention discloses a bidirectional screw wrench with a replaceable rotary sleeve. The bidirectional screw wrench comprises a holding portion, a fixed sleeve connected with the holding portion and the rotary sleeve movably connected with the fixed sleeve. The bidirectional screw wrench is characterized in that the rotary sleeve is in a cylindrical step shape, a lower step is in an inner hexagonal shape, two holes are arranged in the peripheral wall of an upper step of the rotary sleeve, and elastic devices capable of contracting inwards are arranged in the holes. The bidirectional screw wrench with the replaceable rotary sleeve can adjust screw direction by adjusting the matched position between the rotary sleeve and the fixed sleeve. In screwing up and screwing off, the bidirectional screw wrench is convenient to use. In addition, when a fastener is screwed, the rotary sleeve needn't be taken off from the fastener, an angle of the wrench can be adjusted to screw continuously, and accordingly processing efficiency is greatly improved. The bidirectional screw wrench is simple in structure and convenient to operate.
Description
Technical field
The present invention relates to a kind of screwing or the two-way spanner that screws of the interchangeable rotary sleeve of loose nut.
Background technology
In present process of producing product, screw is used very general aborning as a kind of securing member.Common spanner in use, after spanner turn certain angle, spanner need to be taken out from screw, overlap again screw after the adjustment angle and screw again on screw, inefficiency, the friction that institute's the turn of the screw is caused is large, and when narrow and small in the operating space, manually-operated is more difficult, production efficiency is lower, some spanner is single screwing direction in addition, can only tighten or can only unscrew function singleness.
Summary of the invention
The present invention has overcome the defective of prior art, and the two-way spanner that screws of interchangeable rotary sleeve a kind of simple in structure, easy to operate is provided.
Technical scheme of the present invention is: a kind of two-way spanner that screws of interchangeable rotary sleeve, comprise the grip part, the fixed cover that is connected with described grip part, and the rotary sleeve that is flexibly connected with described fixed cover, it is characterized in that: described rotary sleeve is that cylindricality is step-like, get out of a predicament or an embarrassing situation and be that interior hexagon, the described rotary sleeve perisporium of topping bar arranges two holes, is provided with inwardly flexible elastic device in the hole.
Preferably, described fixed cover is U-shaped, and its medial surface perisporium is provided with the sawtooth of the opposite direction that rotates in a circumferential direction, and described elastic device comprises can be resisted against sour jujube tongue on described sawtooth.
Preferably, the inboard perisporium of described fixed cover is provided with two sulculuses radially, and described two sulculuses can pass through for the cooperation of sour jujube tongue simultaneously, and two sour jujube tongues do not abut to described sawtooth simultaneously.
The two-way spanner that screws of interchangeable rotary sleeve of the present invention, the position that can match with fixed cover by adjusting rotary sleeve, screw direction thereby adjust, tighten and unscrew and all facilitate use, do not need when screwing securing member in addition rotary sleeve is taken out from securing member, continue to turn after directly adjusting the spanner angle, thereby greatly improved working (machining) efficiency, simple in structure, easy to operate.
Description of drawings
Fig. 1 is the two-way schematic diagram that screws spanner of the interchangeable rotary sleeve of preferred embodiment of the present invention;
Fig. 2 is the two-way fixed cover cross-sectional schematic that screws spanner of the interchangeable rotary sleeve of preferred embodiment of the present invention;
Fig. 3 is the two-way partial schematic diagram that screws the rotary sleeve of spanner of the interchangeable rotary sleeve of preferred embodiment of the present invention.
The specific embodiment
Below in conjunction with accompanying drawing, the specific embodiment of the invention is described in further detail.
as Fig. 1, 2, shown in 3, the two-way spanner 1 that screws of the interchangeable rotary sleeve in preferred embodiment of the present invention, comprise grip part 2, the fixed cover 3 that is connected with grip part 2, establish a groove 4 in fixed cover 3, the inboard perisporium of groove 4 is provided with sawtooth 14 and the sawtooth 15 of the opposite direction that rotates in a circumferential direction, the inboard perisporium of groove 4 is established and in axial direction also is provided with sulculus 16 and sulculus 17, rotary sleeve 12 is that cylindricality is step-like, get out of a predicament or an embarrassing situation and be interior hexagon 13, top bar the perisporium perisporium along arranging porose 5 and hole 6 perpendicular to radial direction, hole 5 and hole 6 are different along the diametric distance to the terrace 7 of appearing on the stage of rotary sleeve 12, be respectively arranged with inwardly flexible elastic device 8 and elastic device 9 in hole 5 and hole 6, elastic device 8 and elastic device 9 ends are respectively arranged with sour jujube tongue 10 and sour jujube tongue 11, during use, topping bar of rotary sleeve 12 18 is assembled in groove 4, when sour jujube tongue 10 along sulculus 16 during against sawtooth 14, turn rotary sleeve 12, this moment, spanner 1 was a kind of direction that screws, when adjusting sour jujube tongue 11 along sulculus 17 during against sawtooth 15, turn rotary sleeve 12, this moment, spanner 1 was that another screws direction.
Above embodiment is only a kind of of embodiment of the present invention, and it describes comparatively concrete and detailed, but can not therefore be interpreted as the restriction to the scope of the claims of the present invention.Should be pointed out that for the person of ordinary skill of the art, without departing from the inventive concept of the premise, can also make some distortion and improvement, these all belong to protection scope of the present invention.Therefore, the protection domain of patent of the present invention should be as the criterion with claims.
