Abstract

The utility model discloses a rapid adjustment wrench which comprises a wrench head. The wrench head comprises two oppositely-arranged fixing jaws. A jaw opening is formed between the two fixing jaws. Cushion blocks for adjusting the width of the jaw opening are movably arranged in the jaw opening. A rotary shaft is arranged at the position close to the bottom of the jaw opening. The root portion of each cushion block is hinged to the rotary shaft. When the rapid adjustment wrench is used, the size of the jaw opening is not required to be accurately adjusted, the cushion blocks with the proper thicknesses are only required to be moved into or moved out of the jaw opening, the width of the jaw opening can be rapidly adjusted, and therefore the work efficiency is greatly improved.

Description

The fast spanner of adjusting

Technical field

The utility model relates to a kind of hand-operated tools, particularly a kind of fast tune spanner.

Background technology

Spanner is a kind ofly screw or unscrew the instrument that angle screw or nut are arranged, comprise fork spanner and shfting wrench, wherein, mouthful (jaw) spacing of pulling of fork spanner is changeless, so the user generally need to prepare screw or the nut of fork spanner to adapt to different model of Multiple Type; Existing shfting wrench needs to modulate worm gear in use, to adapt to the size of nut, so need to waste certain modulating time while using.

In sum, need a kind of spanner that can increase work efficiency of invention, require this spanner can the quick adjustment jaw size when the clamp nut.

Summary of the invention

In view of this, problem to be solved in the utility model is to provide a kind of fast tune spanner, and this adjusts spanner to save the worm gear modulated structure soon, and size that can the rapid adjustment jaw when the clamp nut, and then has improved the operating efficiency of spanner.

The utility model solves the problems of the technologies described above by following technological means:

Fast tune spanner of the present utility model, comprise driving end, described driving end comprises two opposed fixed jaws, form jaw between two fixed jaws, be provided with the cushion block for the adjusting jaw width in described jaw, bottom near described jaw is provided with rotating shaft, and the root of described cushion block is hinged in described rotating shaft.

Further, the cushion block in described jaw is set side by side with a plurality of.

Further, one among adjacent two cushion blocks is provided with projection, and another is provided with the groove matched with described convex shape; Also comprise flexible member, an end of flexible member is butted on fixed jaw, and the other end is butted on described cushion block.

Further, fixed jaw and with it among the two one of adjacent cushion block be provided with projection, another is provided with the groove matched with described convex shape.

Further, described flexible member is set in described rotating shaft.

Further, described flexible member is rubber ring or spring.

The beneficial effects of the utility model: fast tune spanner of the present utility model, comprise driving end, described driving end comprises two opposed fixed jaws, form jaw between two fixed jaws, be movably set with the cushion block for the adjusting jaw width in described jaw, bottom near described jaw is provided with rotating shaft, and the root of described cushion block is hinged in described rotating shaft.Without the size of accurately adjusting jaw, only need can read soon the width of the jaw adjusted to the cushion block of moving into the cushion block of appropriate thickness in jaw or take out of appropriate thickness from jaw during use, therefore greatly improve operating efficiency.

The accompanying drawing explanation

Below in conjunction with accompanying drawing, the utility model is further described.

Fig. 1 is the structural representation that the utility model is adjusted spanner soon;

Fig. 2 is A district enlarged diagram in Fig. 1;

Fig. 3 is the perspective view that the utility model is adjusted spanner soon;

Fig. 4 is the perspective view that the utility model is adjusted spanner soon.

The specific embodiment

Below with reference to drawings and Examples, the utility model is elaborated:

As shown in Figures 1 to 4, fast tune spanner in the present embodiment, comprise handle 9, be arranged on the driving end 1 of handle end, described driving end 1 comprises two opposed fixed jaws 2, form jaw 3 between two fixed jaws 2, be movably set with the cushion block 4 for adjusting jaw 3 width in described jaw 3, the bottom of close described jaw 3 is provided with rotating shaft 5, and the root of described cushion block 4 is hinged in described rotating shaft 5.Described rotating shaft 5 can be arranged on the position near jaw 3 two bottom sides, after using cushion block 4 to take out of from jaw, can, around the handle place to the jaw back, make and adopt cushion block 4 while adjusting the spanner nutting soon can not hold up and hinder one's work.While using fast tune spanner work of the present utility model without the size of accurately adjusting jaw, only need can read soon the width of the jaw adjusted to the cushion block of moving into the cushion block of appropriate thickness in jaw or take out of appropriate thickness from jaw, therefore greatly improve operating efficiency.

As the further improvement of above-mentioned embodiment, the cushion block 4 in described jaw 3 is set side by side with a plurality of.The thickness of described cushion block 4 equal two adjacent model nut opposite side distance from difference.A plurality of pads are set, and the thickness of each pad equal two adjacent model nut opposite side distance from difference, make the width of jaw can be adjusted to opposite side distance with various model nuts from adapting, compare existing fork spanner and there is significant progress.

As the further improvement of above-mentioned embodiment, one among adjacent two cushion blocks 4 is provided with projection 6, and another is provided with the groove 7 matched with described convex shape; Also comprise flexible member 8, an end of flexible member 8 is butted on fixed jaw 2, and the other end is butted on described cushion block 4.Adjust jaw apart from the time, pull cushion block 4 outside jaw, now, the cushion block extrusion spring, projection 6 skids off from groove 7; When pulling into cushion block to jaw inside, the cushion block extrusion spring, projection 6 slips into locking in groove 7, makes when nutting, and cushion block maintains static.

As the further improvement of above-mentioned embodiment, fixed jaw 2 and with it among the two one of adjacent cushion block 4 be provided with projection 6, another is provided with the groove 7 matched with described convex shape.Described cushion block 4 can closely cooperate with fixed jaw 2 by projection 6 and groove 7 under the promotion of flexible member 8.

As the further improvement of above-mentioned embodiment, described flexible member 8 is set in described rotating shaft 5, and described flexible member 8 is rubber ring or spring.Flexible member 8 is set in rotating shaft 5, has played the effect that promotes cushion block 4, the effect of location flexible member 8 has also been played in rotating shaft 5 simultaneously.

Finally explanation is, above embodiment is only unrestricted in order to the technical solution of the utility model to be described, although with reference to preferred embodiment, the utility model is had been described in detail, those of ordinary skill in the art is to be understood that, can modify or be equal to replacement the technical solution of the utility model, and not breaking away from aim and the scope of technical solutions of the utility model, it all should be encompassed in the middle of claim scope of the present utility model.
