Abstract

The invention provides a novel anchoring nail. An anchoring nail cap is connected with an anchoring nail stud through a spring; a rear clamping nail is arranged at a joint between the anchoring nail cap and the anchoring nail stud; the anchoring nail stud has a hollow structure in which an ejection shaft is arranged; one end of the ejection shaft is fixedly arranged on the anchoring nail cap, penetrates through the anchoring nail stud and is connected with a front clamping nail at the tail end; and the front clamping nail is opposite to the rear clamping nail, and is bent to the center. With the front clamping nail and the rear clamping nail, the novel anchoring nail has a good fixation effect, improves the labor efficiency, is replaceable and recyclable, and prolongs the service life.

Description

A kind of novel anchor nails

Technical field

The present invention relates to engineering accessory field, specifically a kind of have former and later two bails to play the anchor nails of better fixation.

Background technique

Use traditional anchor nails, the time has been grown loosening easily afterwards, and fixed effect is not fine, and not easy to operate.

Summary of the invention

For addressing the above problem, the invention provides a kind of novel anchor nails.

The present invention is achieved in that the holdfast cap links to each other with the holdfast post by spring, its joint is provided with the back bail, the holdfast post is hollow structure, hollow structure inside is provided with apical axis, apical axis one end is fixed on the holdfast cap and runs through the holdfast post and is connected with the preceding bail of end, preceding bail is relative with back bail direction, to the central direction bending.

The beneficial effect of the invention is: have former and later two bails, fixed effect is better, has improved efficiency, and replaceable, recycles, and has prolonged working life.

Description of drawings

Be described further below in conjunction with accompanying drawing.

Accompanying drawing is structural representation of the present invention.

Among the figure: 1, preceding bail, 2, the holdfast post, 3, apical axis, 4, the back bail, 5, spring, 6, the holdfast cap.

Embodiment

Holdfast cap 6 links to each other with holdfast post 2 by spring 5, its joint is provided with back bail 4, holdfast post 2 is hollow structure, hollow structure inside is provided with apical axis 3, apical axis 3 one ends are fixed on the holdfast cap 6 and run through holdfast post 2 and are connected with the preceding bail 4 of end, and preceding bail 1 is relative with back bail 4 directions, to the central direction bending, during use, holdfast cap 6 is depressed, and by the extruding of apical axis 3, bail 1 increases to the central direction crooked radian before making, make holdfast enter anchor hole smoothly, after entering anchor hole, preceding bail 1 recovers, with back bail 4 mutual extrusion, generation is pretended firmly, play good fixation, change as need, press holdfast cap 6, bail 1 is extracted holdfast post 2 out and is got final product to center curvature before making.

Claims (2)

1. a novel anchor nails is characterized in that, the holdfast cap links to each other with the holdfast post by spring, its joint is provided with the back bail, the holdfast post is hollow structure, and hollow structure inside is provided with apical axis, and apical axis one end is fixed on the holdfast cap and runs through the holdfast post and is connected with the preceding bail of end.

2. a kind of novel anchor nails according to claim 1 is characterized in that, preceding bail is relative with back bail direction, to the central direction bending.
