Embodiment Construction

[0010] specific implementation plan

[0011] exist figure 1 Among them, the basic structure of this novel drawing pin of the present invention is divided into three parts: nail cap 1, nail shank 2, and nail tip 3. There is a cross groove 4 in the symmetrical center of nail cap 1, and a cross groove 4 is formed on the nail tip 3 and nail shank 2. Rub has thread 5. The thumbtack of the present invention is made of metal material. When nailing items such as pictures and pictures on the wall, use a screwdriver to insert the cross groove 4 of the thumbtack and rotate clockwise to tighten the thumbtack, so that the nail is loaded, the thumbtack and the nail load will not fall off easily; , insert a screwdriver into the cross groove 4 of the thumbtack and rotate counterclockwise to loosen and remove the thumbtack.

The novel thumbtack is convenient to knock in and less prone to shedding and basically structurally comprises a thumbtack cap, a thumbtack stem and a thumbtack tip. A symcenter of the thumbtack cap is provided with a cross groove to realize utilization of a screw driver when the thumbtack is driven in or taken out; the thumbtack tip and the thumbtack stem are provided with threads to enable the thumbtack to be screwed or unscrewed when the thumbtack is driven in or taken out. The novel thumbtack has the advantages of integral simple structure, simplicity and convenience in operation, time saving, labor saving and high practicality and promotion value.

Description

Technical field [0001] The invention relates to a thumbtack used in daily life, in particular to a new type of thumbtack which is easy to nail off and prevents falling off. Background technique [0002] Thumbtacks are a kind of nail-carrying supplies in daily life. At present, thumbtacks are commonly used, and the ones that are easy to carry and take away are poor in anti-falling off; the ones that are better in tacking and anti-falling off are inconvenient to take away. It is difficult to realize that it is convenient to nail and prevent falling off, which brings inconvenience to people's use and affects people's lives. Contents of the invention [0003] In order to overcome the inconvenience caused by commonly used thumbtacks, the technical problem to be solved by the present invention is to provide a thumbtack used in daily life, especially a new type of thumbtack that is easy to nail and prevents falling off. [0004] The technical solution adopted by the present inv...
