Abstract

The invention discloses a threaded nail puller. The threaded nail puller comprises a nut sleeve and a nail locking tube. The nail locking tube is cylindrical, external threads of the nail locking tube are matched with internal threads of the nut sleeve, two gaps are oppositely formed in the side wall of the lower end of the nail locking tube, a pair of circular-arc-shaped clamping blocks are oppositely arranged on the lower end faces of the lower ends of two pieces of the nail locking tube, wherein the centers of circles of the circular-arc-shaped clamping blocks are opposite, and rubber pads are arranged on the opposite faces of the two circular-arc-shaped clamping blocks. Compared with the prior art, the threaded nail puller has the advantages that when a threaded nail is pulled, the head of the threaded nail is clamped into the circular-arc-shaped clamping blocks on the lower end faces of the nail locking tube, a spanner is utilized to rotate the nut sleeve, the threaded nail is clamped into the nail locking tube, the threaded nail is gradually screwed out along with ascending of the nail locking tube in the nut sleeve, clamping force of the nail locking tube to the threaded nail can be increased through the gaps and the rubber pads, and the anti-skidding effect is achieved.

Description

A kind of drive screw nail puller

Technical field

The present invention relates to a kind of drive screw nail puller.

Background technology

Existing drive screw nail nipping tool mostly is that screw rises, claw hammer, pliers etc., during nail nipping, easily skid, and bad control, efficiency is lower, but also unusual sweat also easily curves drive screw sometimes, affects secondary and uses, and causes the wasting of resources.

Summary of the invention

The problems referred to above that the present invention need to solve are for above-mentioned the deficiencies in the prior art, and a kind of drive screw nail puller is provided.

For solving the problems of the technologies described above, the technical solution used in the present invention is:

A kind of drive screw nail puller, comprise ut socket and pinning pipe, described pinning pipe is cylindrical shape, the outer surface of pinning pipe is provided with external screw thread, the external screw thread of pinning pipe matches with the internal thread of ut socket, the upper end of pinning pipe is threaded connection the one end at ut socket, the lower end of pinning pipe is greater than upper end, and on the sidewall of the lower end of pinning pipe, be relatively provided with the gap that twice are consistent with the axial direction of pinning pipe, on the lower surface of the two halves lower end of the pinning pipe being divided into by twice gap, relatively be provided with a pair of center of circle circular arc fixture block in opposite directions, distance between two circular arc fixture blocks equals the diameter of drive screw, on the opposite face of two circular arc fixture blocks, be provided with rubber blanket.

The length of described ut socket is more than or equal to the length of drive screw.

The width in described gap is less than or equal to 1mm.

Compared with prior art, the invention has the beneficial effects as follows: when playing drive screw, the head of a nail of drive screw is sticked between a pair of circular arc fixture block on pinning pipe lower surface, then use spanner rotating nut sleeve, drive screw is just clamped in pinning pipe, and along with pinning pipe is soaring in ut socket, drive screw is screwed out gradually, gap and rubber blanket can strengthen the chucking power of pinning pipe double thread nail, prevent from skidding.

Accompanying drawing explanation

Fig. 1 is the structural representation of drive screw nail puller of the present invention;

Fig. 2 is pinning end surfaces structural representation.

Wherein, 1, ut socket, 2, pinning pipe, 3, gap, 4, circular arc fixture block, 5, rubber blanket.

The specific embodiment

Below in conjunction with accompanying drawing, describe the preferred technical solution of the present invention in detail.

As shown in Figure 1, a kind of drive screw nail puller, comprise ut socket 1 and pinning pipe 2, described pinning pipe 2 is cylindrical shape, the outer surface of pinning pipe 2 is provided with external screw thread, the external screw thread of pinning pipe 2 matches with the internal thread of ut socket 1, the upper end of pinning pipe 2 is threaded connection the one end at ut socket 1, the lower end of pinning pipe 2 is greater than upper end, and on the sidewall of the lower end of pinning pipe 2, be relatively provided with the gap 3 that twice are consistent with the axial direction of pinning pipe 2, on the lower surface of the two halves lower end of the pinning pipe 2 being divided into by twice gap 3, relatively be provided with a pair of center of circle circular arc fixture block 4 in opposite directions, distance between two circular arc fixture blocks 4 equals the diameter of drive screw, on the opposite face of two circular arc fixture blocks 4, be provided with rubber blanket 5.

The length of described ut socket 1 is more than or equal to the length of drive screw.

The width in described gap 3 is less than or equal to 1mm.

Drive screw nail puller of the present invention, when playing drive screw, the head of a nail of drive screw is sticked between a pair of circular arc fixture block 4 on pinning pipe 2 lower surfaces, then use spanner rotating nut sleeve 1, drive screw is just clamped in pinning pipe 2, and along with pinning pipe 2 is interior soaring at ut socket 1, drive screw is screwed out gradually, gap 3 and rubber blanket 5 can strengthen the chucking power of pinning pipe 2 double thread nails, prevent from skidding.
