Abstract
A novel solid wrench is different from the existing solid wrench in appearance. Clamping surfaces of the solid wrench are two opposite V-shaped grooves forming an included angle of 90-150 degrees instead of two planes with fixed distance and parallel to each other.
Description
Affiliated technical field
The utility model relates to a kind of hand-operated tools that is used for turning outer-hexagonal (comprising Wai Sijiao) screw, is and the visibly different a kind of fork spanner of fork spanner profile that is now using.
Background technology
At present, known fork spanner (comprising single head fork spanner, double ended spanner and combination wrenches) mainly is made up of handle, chuck, is the chuck clamping screw that leans on fixed width, makes the screw rotation.During use, by the size that is turned screw, select the fork spanner of corresponding model, then, spanner clamps by the turn of the screw, pulls handle and makes the screw rotation.General fork spanner, the contact-making surface of its chuck and screw is the parallel plane of two fixed ranges; In use, lean on these two planes, the contact-making surface of (being turned) screw is applied a moment, screw is rotated.Owing to do not have the protruding tenon of start-stop action usefulness on the screw, and do not have corresponding stop draw-in groove on the spanner yet, lean on the clamping on two planes fully, screw is rotated.During use, if turned the shape deformation (screw such situation will occur through repeatedly turning) of screw, difficulty makes to turn failure during fork spanner cartridge clip screw.
Because existing fork spanner generally is a double end, so a kind of double ended spanner can only be used on the screw of two kinds of specifications.
The utility model content
The utility model technical problem to be solved is: the fork spanner (comprising single head fork spanner and combination wrenches) that uses now, and the contact-making surface of its chuck and screw is the parallel plane of two fixed ranges; In use, lean on these two parallel planes, the contact-making surface of (being turned) screw is applied a moment, screw is rotated.Owing to do not have the protruding tenon or the draw-in groove of start-stop action usefulness on the screw, and do not have corresponding stop draw-in groove or tenon on the spanner yet, lean on the clamping on two planes fully, force screw to rotate.During use, if turned the shape deformation (screw such situation will occur through repeatedly turning) of screw, difficulty causes to turn failure during fork spanner cartridge clip screw.
Because existing fork spanner generally is a double end, so a kind of double ended spanner can only be used on the screw of two kinds of specifications, function is on the low side.
The technical scheme that the utility model adopted is: novel V groove double ended spanner is characterized in that: its clamping face is two relative V-shaped grooves, and two face angulations of described V-shaped groove are 120 °; Novel V groove single head fork spanner is characterized in that: its clamping face is two relative V-shaped grooves, and two face angulations of described V-shaped groove are 120 °; The dual-purpose fork spanner of novel V groove is characterized in that: its fork spanner clamping face is two relative V-shaped grooves, and two face angulations of described V-shaped groove are 120 °.With the contact-making surface of fork spanner chuck and screw,, change the V-shaped groove of angled (90 °～150 °) into by a plane.When using spanner, make the V-shaped groove of spanner, aim at the convexity of (to what push up) two same one-tenth hexagonal angles on the screw, when pulling spanner, the V-arrangement draw-in groove on the spanner blocks the convexity on the screw, forces screw to rotate.Like this, spanner is more firm to the clamping of screw, and simultaneously, a double ended spanner can be suitable for the screw of 4 specifications.
The beneficial effect of the utility model: the one,, can protect screw, prevent the wearing and tearing of the outer rib of screw; The 2nd, in use, the scope of application of fork spanner has increased by one times.

The specific embodiment
The one, with the contact-making surface of fork spanner chuck and screw,, change the V-shaped groove of angled (90 °～150 °) into by a plane.
The 2nd, (among Fig. 2) during fabrication; With one now the plane chuck of the fork spanner manufacturing dimension of original fork spanner (promptly by) be fabricated to a kind of specification (as being 12/14) specification, and partly create another kind (as being 14/17) specification with opening V-shaped groove on the plane.Like this, the scope of application with single fork spanner has enlarged one times.
