Abstract
The utility model discloses a conjunction spanner, which is characterized in that a spanner sleeve consists of an opening body and a conjunction moving top head; when the moving top head is embedded in the sleeve, the spanner sleeve is of an orthohexagonal internal opening, and the spanner is used as a sleeve spanner; when the moving top head is removed, the spanner is used as an ordinary opening spanner. The utility model integrates the advantages of the opening spanner and the sleeve spanner, thereby being characterized in simple structure and convenient use.
Description
Technical field:
The utility model belongs to a kind of hardware ﹠ tools, is specially a kind of spanner.
Background technology:
Spanner generally is divided into two classes by its cover head shapes: open-end wrench and box spanner.No matter open-end wrench is monkey wrench or back-up wrench, and it is pullover to be opening, and its advantage is to be easy to from threading path to entering the operating position, and its shortcoming is to use and securing member turret head or nut is deformed skid; Enter the operating position and general sleeve, double offset ring spanner are axial directions from screw thread, be subjected to considerable restraint in the use, its advantage is the turret head or the nut of not easy damaged securing member.
Summary of the invention:
The purpose of this utility model provide a kind of both had open-end wrench from threading path to entering the operating position, easy to use, the novel spanner that has the advantage that sleeve hand, double offset ring spanner do not hinder securing member again.
The technical solution of the utility model is: the cover head part of spanner is by the opening main body and agree with movable top and forms, and angle is corresponding to be connected by agreeing with for the two, embeds to become the both whole hexagons internal orifice when agreeing with movable head, takes off that to become open-end wrench when agreeing with movable the top pullover.
The utility model has the advantages that: simple in structure, radially enter, easy to use, both can embed and agree with movable top and use as box spanner, can take off again and agree with movable top and use as open-end wrench.When wrench was worked, movable top and wrench main body produced certain power under the interaction that agrees with the angle face, kept hexagon internal orifice dimensionally stable, effectively prevented the distortion of wrench hexagon, skidded.Suitably increase the α angle, help movable block and when work, produce to the fastening effect of hexagon internal orifice.
Description of drawings:
Accompanying drawing 1 is a fit-type spanner structure schematic diagram.
1 for agreeing with movable top, and 2 are spanner cover head main body, and 3 are the concavo-convex angle that agrees with.
The specific embodiment:
Embodiment illustrates that the utility model architectural feature is as follows in conjunction with the accompanying drawings:
The fit-type spanner is by spanner handle and wrench is pullover forms, and spanner is pullover by cover head main body 2 with agree with movable top 1 and forms, main body 2 and come directly towards 1 between be connected by the concavo-convex angle 3 that agrees with; The contract mouth is a spill on the main body 2, and the contract mouth is a convex on 1 parts of movable top.
Take off movable top 1, spanner can be used as common open-end wrench and is inserted into the operating position, and uses as open-end wrench; Embedding activity top 1, the pullover internal orifice of spanner is regular hexagon, and spanner becomes box spanner.
Claims (2)
1, a kind of fit-type spanner, by spanner handle with spanner is pullover forms, it is characterized in that: spanner is pullover by the opening main body with agree with movable top and form, angle is corresponding to be connected by agreeing with for the two, the pullover one-tenth both whole hexagons of spanner internal orifice when embedding agrees with movable head takes off that to become open-end wrench when agreeing with movable top pullover.
2, fit-type spanner as claimed in claim 1 is characterized in that: the contract mouth is a spill on the pullover opening main body of spanner, and it is convex that the contract mouth is gone up in the pullover movable top of spanner.
