Rapid nail puller

Abstract

The invention discloses a rapid nail puller. The rapid nail puller comprises a U-shaped support, a handle segment and a supporting segment. The supporting segment is arranged on the support in a rotating mode through a hinging shaft. A moving rod is arranged in the supporting segment in a sliding mode, one end of the moving rod is connected with a pushing plate, and a nail pulling piece is fixed to the other end of the moving rod. Reinforcing blocks are fixed to the upper portions of the two side walls of the supporting segment, the two ends of the lower surface of each reinforcing block protrude downwards to form a ridge-shaped contact surface, and the upper surface of the moving rod is matched with the lower surfaces of the reinforcing blocks. The nail pulling piece is composed of a connecting segment and a nail pulling segment connected with the connecting segment, the upper surface of the nail pulling segment is a horizontal plane, the lower surface of the nail pulling segment is an inclined plane, an acute angle is formed between the horizontal plane and the inclined plane, and the tail end of the nail pulling segment is provided with an arc groove in the direction where the end face of the nail pulling segment points to the connecting segment, wherein a steel nail body can pass through the arc groove. The acting force which an operator needs to apply when inserting the nail pulling segment into a board in an inclined mode is greatly reduced, so that the time for pulling out a single steel nail is directly shortened, and the nail pulling efficiency is improved.

Description

technical field [0001] The invention relates to the field of recycling wooden molds for exterior walls, in particular to a quick nail puller. Background technique [0002] When pouring the foundation of a building, wood formwork or steel formwork is required for external fixing and molding, and wood formwork is more widely used than steel formwork because of its lower cost. When the wood formwork is fixed, the drawing screw is mainly used for overall fixing, and the steel nail is used for auxiliary fixing. After the poured concrete is solidified, the wooden formwork needs to be dismantled, but a large number of steel nails will remain on the wooden formwork composed of wooden boards, and many steel nails are easily scratched or nailed during the disassembly process. Wearing the feet of the construction workers on the construction site, and the excessive residue of steel nails are not conducive to the next fixed use of the wooden board.

AI Technical Summary

Problems solved by technology

After the poured concrete is solidified, the wooden formwork needs to be dismantled, but a large number of steel nails will remain on the wooden formwork composed of wooden boards, and many steel nails are very easy to be scratched or nailed during the disassembly process. Wearing the feet of construction workers on the construction site, and too many steel nails are not conducive to the next fixed use of wooden boards
