Description

Spiral safety drawing pin

Technical Field

The utility model relates to a drawing pin for common stationery, in particular to a spiral safety drawing pin which has reasonable structure, prevents the puncture of a spiral telescopic needle rod, and has the dual purposes of inserting the nail and attracting magnetism.

Background

The drawing pin is a common stationery, can temporarily fix light articles such as paper and the like at a display position, is easy to replace and is convenient to carry. The problem is that the stitches of the common pushpin are exposed outside, so that a user, particularly an infant without nursing people, is easily stabbed in the using process; meanwhile, the single pin is easy to bend due to improper operation and has insufficient firmness; when the working interface is made of magnetic attraction metal materials, the pin drawing pin needs to be replaced by the magnetic attraction drawing pin, so that the economic cost is increased invisibly, and the resource saving is not facilitated. Compared with the safety thumbtack with the built-in spring, the spiral safety thumbtack provided by the invention has the advantages that the thumbtack can be pushed out more safely by pressure, the structure is simple, the realization is easy, and the problems are effectively solved.

SUMMERY OF THE UTILITY MODEL

The utility model relates to a spiral safety drawing pin, which aims to solve the problem that the common drawing pin is easy to stab a user, in particular to an infant without nursing; meanwhile, the single pin is easy to bend due to improper operation and has insufficient firmness; and the problem that the pin drawing pin needs to be replaced by the magnetic metal drawing pin is solved, and the spiral safety drawing pin which is simple in structure, easy to realize, safe and reliable is provided.

The utility model discloses the scheme that adopts is:

the spiral safety drawing pin mainly comprises a spiral pin cap body button, a drawing pin shell body, spiral sliding blocks with bulges at two ends, a groove track on the inner wall of the drawing pin shell body, a pin rod, a magnet and a pin outlet hole, wherein the upper end of the drawing pin shell body is connected with the spiral pin cap body button, and the lower end of the drawing pin shell body is connected with the magnet; the spiral sliding block with bulges at two ends is connected with the screw rod part of the screw cap body button part, and the lower end of the spiral sliding block is connected with the screw rod; the groove track on the inner wall of the thumbtack shell body is connected with the spiral sliding blocks with bulges at two ends; the nail rod can penetrate through the nail outlet hole.

During the use, will the cap body button of spiral nail piece clockwise rotation drives have bellied spiral slider with the nail pole, along the drawing pin shell inner wall recess track outwards removes, the nail pole runs through out the nail hole, alright insert the working face as required and use, or carry out the magnetite adsorbs the use.

In fact, the double-stitch design is firmer and more stable than a single stitch, is not easy to bend and is more durable. The nail magnetic dual-purpose is favorable to the resource cost saving.

The utility model has the advantages that:

the spiral safety drawing pin is simple in structure, easy to achieve, convenient and fast to operate, controllable in length of the spiral lifting needle rod, safe in puncture prevention, dual-purpose in nailing and magnetism, and favorable for saving resource cost.
