Technical Field

The invention relates to a pulling device, in particular to a building template nail pulling device.

Background

Before pouring the ceiling to the building, need use the nail to the template concatenation, make the template build the model that need pour, then pour concrete, need demolish the template after concrete solidifies, owing to all connect a lot of nails in the template after demolising, need pull out the nail and retrieve, also make things convenient for the template transport, in order to practice thrift the cost of labor now many building sites, directly carry the template that has the nail, directly carry and do not demolish easily to cause the injury to the workman to the nail on the template.

Current demolish the nail on the template and all adopt hand tool, and hand tool is not only inefficiency, but also complex operation, influences the engineering progress.

Disclosure of Invention

In order to overcome the defects that the conventional manual tool is adopted for removing the nails on the template, the manual tool is low in efficiency and complex in operation and influences the engineering progress, the invention has the technical problems that: the utility model provides a can retrieve the nail fast, can not cause the building templates nail pulling device of injury moreover to the workman.

The utility model provides a building templates nail pulling device, including the handle, open the bottom of handle has the recess, still including slider, the fixed plate, clamping device and a circular cylinder, the middle part of recess is equipped with slider, slider is used for driving the nail rebound, slider's bottom fixedly connected with fixed plate, the front side of fixed plate is equipped with clamping device, clamping device is used for pressing from both sides the nail tightly, the inboard fixedly connected with circular cylinder in bottom of recess, circular cylinder inner wall is opened there is the internal thread, internal thread and external screw thread engagement.
