Abstract

The utility model relates to a power nail extractor, which is provided with a head restraint with a bayonet. The upper end of the head restraint is flexibly connected with the lower end of a screw. The upper end of the screw is provided with a power joint. A screwed sleeve is sleeved on the screw active cooperation part. The rotation of an engine drives the screw to rotate. The screw rotates and moves upwards relative to the screwed sleeve and drives the head restraint and the nail to move upwards, thereby successfully extracting the nail. The lower end face of the screwed sleeve is of figured face or serrated face or wavy face, which increases the friction of the wooden material around the screwed sleeve and the nail and enhances the reliability in nail extraction.

Description

Dynamic nail extractors

Technical field:

Dynamic nail extractors is to be used to extract wooden interior iron nail utensil, particularly with the nail extractor vertically directly fast extracted of power along iron nail.

Background technology:

Existing nail extractor all has band to be stuck in the dop of the bayonet socket of the head of a nail, and the dop that has bayonet socket is connected with the handle of driving.Driving handle drives bayonet socket and nail and tilts to move, thereby extracts nail; But the process of nail pulling tilts to the stressed of the head of a nail and nail, makes that the force rate of extracting nail is bigger, and it is time-consuming require great effort, and will damage nail hole and wood on every side.Existing dynamic nail extractors all is the motor driven gear reducing gear nail pulling dop of driven rotary again, makes dop tilt to move, the process of nail pulling tilts to the stressed of the head of a nail and nail, energy consumption is bigger, frame for movement more complicated heaviness, operation more complicated.

Summary of the invention:

The present invention is exactly the problem that solution complex structure, nail pulling are relatively required great effort, and provides a kind of simple in structure, and cost of manufacture is low, easy to operate dynamic nail extractors.

The present invention is in order to address the above problem, and dynamic nail extractors of the present invention has dop with bayonet, it is characterized in that: the dop upper end is connected with the screw rod lower end is active, and the screw rod upper end has power sub, and screw rod is with threaded sleeve movingly.Like this, the bayonet socket of dop is stuck in below the head of a nail, the power sub of screw rod upper end is connected (as being connected with motor shaft or being connected with the electric drill anchor clamps or being connected with I. C. engine crankshaft) with the power engine of rotation, rotation by engine drives the screw rod rotation, screw rod rotates on moving dop of shipper pole and the nail relative to screw shell and moves, and vertically successfully extracts nail.In order to increase the frictional force of the material such as wooden around screw shell and the nail, increase the reliability of nail pulling, the threaded sleeve lower surface is decorative pattern face or toothed surface or corrugated surface, material such as wooden around decorative pattern face or toothed surface or corrugated surface and the nail contacts like this, can increase resistance greatly, avoid the possibility of screw shell rotation, improve the reliability of work.

Description of drawings:

Accompanying drawing has represented that nail combines generalized section in a kind of dynamic nail extractors structure of the present invention and the plank, further specifies below in conjunction with the example of accompanying drawing.

Specific embodiment: dynamic nail extractors of the present invention shown in this accompanying drawing, dop 4 with bayonet is arranged, the dop inboard has goat's horn, has down dovetail groove along goat's horn continuously to the middle part.Dop upper end multidiameter and 7 sockets movingly of cored screw lower end annular bearing, the multidiameter upper end is fixedly connected with chuck 8 by screw 9, forms active connection.Cored screw 2 upper end stationary fits are fixed with power sub 1.Cored screw is with threaded sleeve 3 outward movingly.Like this, dop is stuck in down the bayonet socket of dovetail groove by its goat's horn transition with the head of a nail of nail 5 upper ends, forms the bayonet socket inboard and is stuck in below the head of a nail.The power sub 1 of screw rod upper end is connected with the power engine that rotates.Can be connected with motor shaft by shaft joint, also can be connected with the I. C. engine crankshaft end by shaft joint.Best, most convenient is that power sub is connected with the electric drill anchor clamps, and geometrical clamp is in the electric drill anchor clamps.Relatively rotate screw shell and move down, withstand on the plank upper surface.By the rotation of engine,, drive cored screw and rotate, and the screw shell lower end withstands on plank 6 upper surfaces, also just rotates relative to screw shell as driving electric drill.Cored screw 2 rotates relative to screw shell and dop, and it rises along threads turn, drive the relative plank of dop and nail and rise, and the vertical panel face is successfully extracted nail 5.So just nail is extracted in the labour-saving fast, and not crooked nail does not destroy the nail hole, does not damage the plank surface yet.Plank around the toothed surface or the corrugated surface of threaded sleeve lower surface wedge angle, toothed surface or corrugated surface and nail holds out against, and just increases resistance greatly, improves the reliability of work greatly.

Claims

1. a dynamic nail extractors has dop with bayonet, it is characterized in that: the dop upper end is connected with the screw rod lower end is active, and the screw rod upper end has power sub, and screw rod is with threaded sleeve movingly.

2. as the said dynamic nail extractors of claim 1, it is characterized in that: the threaded sleeve lower surface is decorative pattern face or toothed surface or corrugated surface.
