Description
Technical field
The utility model relates to hardware & tools technical field, relates in particular to a kind of monkey wrench.
Background technology
Monkey wrench is conventional instrument in production and life, and major part is all to utilize lever principle to twist opening or trepanning firmware that bolt, screw, nut and other screw threads are tightly held bolt or nut.Spanner is conventionally shaped with clamp holder portion and applies external force shank and apply external force in the one or both ends of shank, the actual comparatively effort of using.
Summary of the invention
The technical problems to be solved in the utility model is to provide a kind of simple in structure, more labour-saving spanner.
The utility model is realized by the following technical solutions: adopt shaft-like caliper, comprise the first tong arm and the second tong arm, the first jaw and the second jaw, the first tong arm and the second tong arm are hinged by main shaft, the first tong arm and the second tong arm top arrange sector rack, the structure that the first described jaw and the second jaw are dovetail groove, is embedded with spanner, and the second described jaw is moving jaw; The first jaw is fixedly connected with by the first bolt with the first tong arm, the second described jaw is fixedly connected with by the second bolt with the second tong arm, the rear portion of the second jaw has horizontal guide slot, the built-in thumb wheel of gathering sill, the screw rod other end being fixedly connected with thumb wheel is fixedly connected with the second jaw, stir thumb wheel, can make the second jaw way moving in gathering sill.
As preferred technical scheme, described spanner adopts Luo vanadium steel material to make.
By using the beneficial effects of the utility model: by adjusting thumb wheel, fine-tuning two jaw distances, guarantee wrench and the complete close contact of hexagonal work piece on the first jaw and the second jaw, be difficult for getting loose, utilize the moving principle of tooth to make the direction of clamp power constant with size, more laborsavingly more have superiority, simple in structure, easy to use.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model.
The specific embodiment
In the present embodiment, with reference to adopting shaft-like caliper shown in Fig. 1, bag adopts shaft-like caliper, comprise the first tong arm 1 and the second tong arm 2, the first jaw 3 and the second jaw 4, the first tong arms 1 and the second tong arm 2 are hinged by main shaft 5, and the first tong arm 1 and the second tong arm 2 tops arrange sector rack 11, the structure that the first jaw 3 and the second jaw 4 are dovetail groove, is embedded with spanner 10; The second jaw 4 is moving jaw, the first jaw 3 is fixedly connected with by the first bolt 6 with the first tong arm 1, the second described jaw 4 is fixedly connected with by the second bolt 7 with the second tong arm 2, the rear portion of the second jaw 4 has horizontal guide slot 8, the built-in thumb wheel 9 of gathering sill, the screw rod other end being fixedly connected with thumb wheel is fixedly connected with the second jaw 4, and thumb wheel thumb wheel 9 can make the second jaw 4 at the interior way moving of gathering sill 8.
Wherein, spanner 10 adopts Luo vanadium steel material to make.
By adjusting thumb wheel, fine-tuning two jaw distances, guarantee wrench and the complete close contact of hexagonal work piece on the first jaw and the second jaw, are difficult for getting loose.Utilize the moving principle of tooth to make the direction of clamp power constant with size, more laborsavingly more have superiority, simple in structure, easy to use.
Obviously, those skilled in the art can carry out various changes and modification and not depart from spirit and scope of the present utility model the utility model.Like this, if of the present utility model these are revised and within modification belongs to the scope of the utility model claim and equivalent technologies thereof, the utility model is also intended to comprise these changes and modification interior.
