The driving end is with outer square structure compatible with the screw hole of screw or with being adapted with screw head Interior square hole structure.
The resilient clamp bodies coordinate with driving end to grip screw.
The resilient clamp bodies are one.
The head end of the resilient clamp bodies is at least two circle helical structure made of elastic wire.
The resilient clamp bodies have when by screw hole hole opening's edge block when the rollback structure that can retract.
The resilient clamp bodies include the connecting rod of the supporting rod and integrally connected supporting rod and head end of end, connecting rod by It tilts and overhangs to preceding separate wrenching bar afterwards, supporting rod is tilted to overhang by rear to preceding close wrenching bar constitutes the rollback structure.
There are one the folding portion turned down outward, folding portion has to be coordinated the end tool of the supporting rod with screw head pushing tow With the pushing tow face of spreading supporting rod.
The front end of the folding portion is concordant with driving end.
Beneficial effects of the present invention are:Be provided on wrenching bar head end be connected with wrenching bar it is endwise resiliently overhanged Resilient clamp bodies, resilient clamp bodies are close to screw head and apply radial elastic active force to be gripped to screw, solve In the prior art due to intermediate plate does not have elasticity and need to be arranged sliding ring changing the distance between two intermediate plates to be clamped or Screw is unclamped so as to cause complicated problem, and the spanner structure of the structure is simple, easy to use.
Further, resilient clamp bodies have rollback structure, when needing trip bolt again or will not be because when unscrewing screw End for the hole opening's edge block resilient clamp bodies of screw hole causes spanner to be not easy to be inserted into asking in the screw hole of screw head Topic.
Further, the end tool of resilient clamp bodies is there are one the folding portion turned down outward, and folding portion has and head of screw Portion's pushing tow cooperation can be with clamp screws in assembly with the pushing tow face of spreading supporting rod, not only, also can be convenient to spiral shell in dismounting The clamping of nail avoids accidentally falling screw in dismounting.
