Handheld device for vertically pulling iron nail

Abstract

The invention discloses a handheld device for vertically pulling an iron nail. The handheld device for vertically pulling the iron nail comprises two clamps, a clamp fixing seat, a pin shaft, a spring, a steel rope, a pulley, a handle, a switch, a motor, a worm, a gear, a transmission wheel, a connecting rod, a pull block and a case. The two clamps rotate on the clamp fixing seat through the pin shaft. The clamps and the clamp fixing seats slide in the case. One end of the steel rope is connected with the clamps, and the other end of the steel rope is connected with the pulling block. The pulling block move downwards to drive the clamps and the clamp fixing seat to slide upwards through the steep rope. The motor drives the worm, the gear and the transmission wheel to rotate so as to enable the pulling block to slide up and down through the connecting rod. According to the structure, the two clamps are opened and placed at the to-be-pulled iron nail, the motor is started to drive the pulling block to move downwards, the clamps are pulled through the steep rope to clamp the iron nail, and then the clamps continue moving upwards to vertically pull out the iron nail. The handheld device for vertically pulling the iron nail has the beneficial effects that the iron nail can be vertically pulled out, accordingly the building construction cost is reduced, the efficiency is improved, the resources are saved, and meanwhile the handheld device for vertically pulling the iron nail is simple in structure and convenient to operate.

Description

technical field [0001] The invention relates to the field of building construction, in particular to a hand-held vertical nail pulling device. Background technique [0002] Iron nails are commonly used by people to connect and fix wooden parts, because they are cheap and easy to operate. During building construction, a large number of iron nails will be used. In many cases, iron nails need to be pulled out in order to reuse wooden parts; prior art It is to use a nail hammer to pull out the iron nails. The nail hammer pulls out the iron nails relying on the action of the oblique force on the iron nails. The hole of the nail to be pulled out will become larger and damage the surface of the component. For example, for parts with high surface requirements, it cannot be pulled out with a nail hammer; In addition, the iron nails that are pulled out will become bent, and the iron nails must be straightened before they can be used again, or they can only be discarded. Manually pulli...

AI Technical Summary

Problems solved by technology

It solves the problem of not damaging the surface of the component when the nail is pulled out, but the device cannot quickly put the nail into the groove in the middle of the nail removal hook, the efficiency is slow, and the labor intensity of manual removal of the nail is high
