Detailed ways

In order to better understand the technical content of the present invention, specific embodiments are provided below, and the present invention is further described with reference to the accompanying drawings.

Referring to FIGS. 1 to 4 , the present invention provides a construction safety protection device, comprising a positioning base plate 1 , a fixing cylinder 2 , a connecting portion 3 and a handle 4 , and the fixing cylinder 2 is installed on the top of the positioning base plate 1 . , the center of the fixing cylinder 2 is hollowed out in the horizontal direction, the fixing cylinder 2 is provided with a positioning frame, the front end of the positioning frame is provided with a positioning hole 6 for placing iron nails, and the connecting portion 3 is vertically installed on the The top of the fixed cylinder 2, the handle 4 is fixedly connected with the connecting portion 3.

The positioning frame includes a positioning clip 5 and a torsion spring. The positioning clip 5 is divided into an engaging portion 501 at the front end and a hinge portion 502 at the rear. The positioning hole 6 is located at the engaging portion 501, and the height of the engaging portion 501 is greater than the height of the hinge portion 502, thereby The depth of the positioning hole 6 is increased, and the iron nail has a better stabilization effect. The spring is sleeved on the outside of the pin shaft 8 , and both ends of the pin shaft 8 are rotatably connected with the upper and lower inner walls of the fixing cylinder 2 .

When using, first place the positioning base plate 1 on the plate that needs to be nailed, and apply pressure to the positioning base plate 1 through the handle 4 to ensure the stability of the positioning base plate 1. The positioning clip 5 is in a natural state, the front end is in an engaged state, and the positioning hole 6 is located at the occlusal position, pass the tip of the iron nail through the positioning hole 6, and the positioning hole 6 is perpendicular to the positioning bottom plate 1. At this time, hold the handle 4 with one hand and continue to press the positioning bottom plate 1, and the other hand can knock it with a hammer. When hitting the top of the nail, the handle 4 is inclined to the vertical direction, so that the hand holding the handle 4 is kept away from the striking track of the hammer to ensure that the hand will not be hurt when the nail is struck. The nails are supported and the verticality of the nails and the plate is ensured, so that the nails are vertically nailed into the plate under the knock of the hammer. The fixing cylinder 2 is located at the lower part of the whole device, next to the positioning bottom plate 1. When the top of the nails moves down and approaches At the top of the positioning hole 6, the iron nail has been nailed to a certain depth and is relatively firm. At this time, the tail of the positioning clip 5 can be pressed, so that the positioning hole 6 at the front end of the positioning clip 5 is opened to both sides, and the device is taken out at the same time. Use a hammer to hammer the rest of the nail into the board. The device can prevent the workers from directly supporting the nails with their hands, effectively preventing the accidental injury of the hammer to the hands when knocking the nails. Improve the nail effect.

The top of the fixing cylinder 2 is provided with a threaded hole, the threaded hole communicates with the interior of the fixing cylinder 2, and the fixing cylinder 2 is provided with a clamping plate 9 for pressing the positioning clip 5.
