Connecting screw hilt hands.The described screwdriver clamping any material screw also includes spring, and spring one end is even
Connecting handle, one end connecting screw hilt hands.
It is provided with reinforcing plate at described bending chuck arc opening, reinforcing plate is provided with identical with bending chuck
Arc opening.
Arranging an installing hole on described screwdriver, nail pressing includes guide rod, nut, and guide rod is arranged in installing hole,
The two ends of guide rod are provided with screw thread.
Described installing hole is pin-and-hole, is bearing pin in the middle part of guide rod, is interference fit or mistake between guide rod and installing hole
Degree coordinates.
Beneficial effects of the present invention:
1. present configuration is simple, durable, owing to handle is arranged on screwdriver handle side, and can the palm of the hand during operation
Hold screwdriver handle, finger manipulation handle, it is achieved one-handed performance, be effectively increased work efficiency, reduction
Labor intensity.
2., by arranging extension spring or spring, the operation to cartridge clip is the most laborsaving, convenient.
3., by arranging reinforcing plate on the basis of the realization not affecting function, add the clamping face of screw
Long-pending, ensure that what screw fastened smoothly completes.
4. by arranging guide rod, nut, the position of conveniently adjusted nut, make the bending of two intermediate plate front ends press from both sides
Head opening angle is identical, thus after ensureing pinching screw, screw is just to driver bit, and beneficially screw is tight
Correcting during Gu.
5., by installing hole being set to pin-and-hole, being set to bearing pin in the middle part of guide rod, having ensured nail pressing two further
The symmetry of side, thus after ensureing pinching screw, screw is just to driver bit, and beneficially screw fastened
Correcting in journey.
