Description
Technical field
The utility model relates to a kind of jaw spanner, is mainly used in to pull as round nut handles such as conduit switch, tracheae switches.
Background technology
The round nut spanner that uses mostly is sheet greatly now, skid easily when thin round nut handle is applied torsion, main cause is that the slight side partially of spanner when the application of force causes the stress point of spanner and round nut to be failed to remain on the same straight line and the sideslip of generation is caused.Make troubles to the user.
The utility model content
The purpose of this utility model provides a kind of above-mentioned defective that overcome, and can prevent to skid the jaw spanner of increasing work efficiency greatly effectively.
A kind of jaw spanner, comprise handle, claw type circular arc spanner, draw pin and supporting pin, claw type circular arc spanner is below handle, described claw type circular arc spanner is made up of two claw type arc plates, be provided with between two claw type arc plates that be arranged in parallel and draw pin and supporting pin, draw pin and supporting pin vertical fixing in the both ends of two claw type arc plates.
Described handle and draw pin and the supporting pin line between angle α be 0 the degree-90 the degree.
Described handle and draw pin and the supporting pin line between angle α be 70 the degree.
The utility model is simple and practical, and is reliable and secure.Because the round nut handle of being pulled when using is between two claw type arc plates that be arranged in parallel, so the time to the handle application of force, the stress point of wrench and round nut handle can remain on same plane, thereby effectively prevents the problem of skidding that causes because of the inclined to one side side of spanner, and has guaranteed safe in utilization.The utility model is applied widely, is particularly useful for pipe switch of work-yard narrow and toxic and harmful or liquid etc.
