Abstract

The utility model discloses a nail holding device, which comprises a first nail holding plate and a second nail holding plate. Two convex key pins are arranged on the first nail holding plate, two concave key pins are drilled in the second nail holding plate, the first nail holding plate and the second nail holding plate are combined integrally by means of matching of the two convex key pins and the two concave key pins, and three guiding holes with different apertures are drilled at a combination position of the first nail holding plate and the second nail holding plate. The nail holding device is novel in design, simple in structure and convenient in use, the trouble that a nail is nailed askew is avoided, furthermore, operators can be protected, and fingers of the operators are prevented from being injured by a crashing hammer.

Description

A kind of rotary screw device

Technical field

The utility model relates to a kind of instruments of labour, concrete relates to a kind of rotary screw device.

Background technology

Usually with the hand steered nail of living, so,, follow closely askewly easily when nailing, influenced operating efficiency because people's uncertainty often shakes by the hand channel of nail; Two just because of follow closely askew easily or basic just nail partially, so just there is hammer to injure the possibility of finger by a crashing object, operating personnel's personal safety has been caused potential safety hazard.

Summary of the invention

For addressing the above problem, the utility model provides a kind of rotary screw device, both can the fixing anti-non-magnetic shim of nail is askew, and can protect finger to avoid the possibility that is injured by a crashing object by hammer again.

For realizing above-mentioned technical purpose; Reach above-mentioned technique effect; The utility model is realized through following technical scheme: a kind of rotary screw device; Comprise that first holds up nail-plate and second to hold up nail-plate, said first holds up nail-plate to be provided with two convex key pins, and said second holds up and be drilled with two spill key pins in the nail-plate; Said first holds up nail-plate and said second to hold up nail-plate integrated through said two convex key pins and said two spill key pins cooperation, and said first holds up nail-plate and said second to hold up the junction of nail-plate to be drilled with the pilot hole in three different apertures.

Further, said first hold up nail-plate and said second to hold up also to be carved with anti-skidding line on the nail-plate.

The principle of the utility model is: the utility model is a kind of rotary screw device, and rotary screw device holds up nail-plate to form by two, links to each other through key pin; Hold up the junction of nail-plate to design the gathering sill that several specifications do not wait for two, according to the size of nail, the gathering sill of selecting to be fit to inserts; Rotary screw device is placed on the place that need nail after clamping nail, holds up and also is carved with many anti-skidding lines on the nail-plate; With hand steered firmly rotary screw device, nail hammers into through gathering sill.

The beneficial effect of the utility model is:

The utility model is novel in design, and is simple in structure, easy to use, solved the askew trouble of nail when nailing; The utility model can also be protected operating personnel's safety, prevents that finger from being injured by a crashing object by hammer.
