Abstract
The utility model belongs to tools applied to the technical field of machines, in particular to an improved screw rod wrench. The improved screw rod wrench comprises a regular jaw and an adjustable jaw. The ends of two parallel guide posts are fixedly connected to the regular jaw. A shaft hole is formed in a jaw base on the portion, between the two guide posts, of the regular jaw. The other ends of the two guide posts are fixedly connected with a connecting board. A through hole is formed in the portion, between the two guide posts, of the connecting board. A screw rod is installed between the two guide posts. An end shaft of one end of the screw rod is matched with the shaft hole of the jaw base of the regular jaw and a shaft rod of the other end of the screw rod is matched with the through hole in the connecting board. A threaded hole in a jaw base of the adjustable jaw is matched with the screw rod. Two through holes of the jaw base of the adjustable jaw are matched with the two guide posts in a movable mode. The shaft rod, penetrating out of the through hole of the connecting board, of the screw rod is fixedly connected with a rod base provided with an inserting hole and a handle is installed in the inserting hole of the rod base in a matched mode. The improved screw rod wrench is reasonable and simple in structure, safe and reliable in performance, high in work efficiency, small in size, convenient to carry and low in cost and allows the distances of the jaws to be adjusted conveniently.
Description
Technical field
The utility model belongs to the instrument, particularly a kind of improved screw mandrel spanner that field of mechanical technique is used.
Background technology
At present, screw mandrel spanner is various informative, of many uses, but traditional screw mandrel spanner wants extremely effort of adjusting jaw distance, and conditioning equipment is comparatively huge, and jaw is easily loosening, after becoming flexible, can not again step up.Effort, time-consuming in the course of work, and inefficiency.So be badly in need of a kind ofly can laborsavingly regulating, jaw is convenient to the screw mandrel spanner clamping.
Utility model content
The purpose of this utility model is to provide a kind of improved screw mandrel spanner, and it is rational in infrastructure, simple, and the distance of adjusting jaw is very convenient, and performance safety is reliable, and operating efficiency is high, and volume is little, easy to carry, with low cost.
The purpose of this utility model is achieved in that a kind of improved screw mandrel spanner, comprise regular jaw and moving jaw, two its one end of guide pillar being parallel to each other affixed regular jaw, on the regular jaw jaw seat between two guide pillars, axis hole is being set, the other end of two guide pillars affixed connecting plate, on the connecting plate between two guide pillars, through hole is being set, between two guide pillars, screw mandrel is installed, the end axle of screw mandrel one end matches with the axis hole of regular jaw jaw seat, the axostylus axostyle of the screw mandrel other end matches with the through hole of connecting plate, screw on moving jaw jaw seat matches with screw mandrel, two through holes on moving jaw jaw seat coordinate with two guide pillars are moving, stretching out affixed the pole socket with jack on the screw mandrel axostylus axostyle of connecting plate through hole, in the jack of pole socket, coordinate handle is installed.
Regular jaw of the present utility model is fixed in the head of guide pillar, guide pillar coordinates with moving jaw jaw seat is moving, screw and the screw mandrel of moving jaw jaw seat are threaded connection, the jack of screw mandrel column base is six rib jacks, during work, handle six rib ends is inserted in the jack of screw mandrel pole socket, rotary handle, just can make screw mandrel rotation, screw mandrel rotation can drive moving jaw to slide, thereby makes the moving jaw adjusting jaw size that moves around carry out work.
Beneficial effect is: reasonable in design, simple in structure, with low cost, durable, safe and reliable, working range is large, easy to carry, is easy to the advantages such as adjusting.
The utility model is simple and reasonable for structure, and the distance of adjusting jaw is very convenient, and performance safety is reliable, and operating efficiency is high, and volume is little, easy to carry, with low cost.
Accompanying drawing explanation
Below in conjunction with accompanying drawing, the utility model is further described, Fig. 1 is perspective view of the present utility model.
The specific embodiment
A kind of improved screw mandrel spanner, as shown in Figure 1, comprise regular jaw and moving jaw, two guide pillars, 1 its one end of being parallel to each other affixed regular jaw 6, on regular jaw 6 jaw seats between two guide pillars 1, axis hole is being set, the other end of two guide pillars 1 affixed connecting plate 7, on the connecting plate 7 between two guide pillars 1, through hole is being set, screw mandrel 5 is installed between two guide pillars 1, the end axle of screw mandrel 5 one end matches with the axis hole of regular jaw 6 jaw seats, the axostylus axostyle of screw mandrel 5 other ends matches with the through hole of connecting plate 7, screw on moving jaw 2 jaw seats matches with screw mandrel 5, two through holes on moving jaw 2 jaw seats coordinate with two guide pillars 1 are moving, stretching out affixed the pole socket 3 with jack on the screw mandrel axostylus axostyle of connecting plate through hole, in the jack of pole socket 3, coordinate handle 4 is installed.
