Abstract
The invention discloses a drawing pin. The drawing pin comprises a pin cap and a pin rod and is characterized in that the pin cap is flat, burrs are reserved on the pin rod, and barbs are arranged at the bottom end of the pin rod. The pin cap is simple in design and free of corners and therefore will not cause accidental scratches, and when the drawing pin is left unused, the pin point will not face upwards. By the adoption of the structure, the drawing pin can drill a hole in a cement wall conveniently; as the drawing pin and a soft material in a drawing pin sleeve can be fixed through the burrs, use is safe; as the barbs are used, friction force is increased, fixity is high, and the drawing pin will not loosen or fall off.
Description
Technical field
The present invention relates to a kind of drawing pin.
Background technology
Existing drawing pin uses extensively, usually be used to be fixedly connected with object, traditional drawing pin, after making, nail bar is smooth, there is no the design what is innovated, this just makes to bind in process easily to loosen, and figure head of a nail great majority are all oval in shape, and its edge is too sharp, easily scratch finger when binding, because drawing pin volume is little, easily lose, certain hidden danger can be there is.Tradition drawing pin is made into as straight drawing pin, and in use procedure, tightness is low, is not easy to fix with the soft material in thumb pin sleeve, not too safe, and after dropping, nail tip, easily can stab people upward.
Summary of the invention
The object of the invention is: provide a kind of safe handling, simplicity of design, stationarity is strong, the drawing pin that can not loosen.
Technical scheme of the present invention is: a kind of drawing pin, and comprise the head of a nail and nail bar, the described head of a nail is flat, and described nail bar leaves burr, arranges barb in nail bar bottom.
The material of the described head of a nail is elastomeric material.
Two hooks of described barb are symmetrical, and size is identical.
Described burr with between burr to follow closely distance on bar equal.
In the process of nail, can make to compare effort when just having started impact owing to being provided with barb, need to get hold of dynamics, nail is when idle, and due to the particularity of its design, nail tip can not upward, use safety.
The advantage that the present invention has and good effect are: head of a nail simplicity of design, there is no corner angle, can not surprisingly scratch, and time idle, nail tip can not be upward, after adopting said structure, convenient boring on cement wall, can be fixed with the soft material in thumb pin sleeve by burr, safe handling, due to the use of barb, strengthen frictional force, stationarity is strong, can not loose or dislocation.
Accompanying drawing explanation
Fig. 1 is structural representation of the present invention
Wherein 1, the head of a nail 2, nail bar 3, burr 4, barb
Detailed description of the invention
A drawing pin as shown in Figure 1, comprise the head of a nail 1 and nail bar 2, the described head of a nail 1, in flat, described nail bar 2 leaves burr 3, arranges barb 4 in nail bar 2 bottom.
The material of the described head of a nail 1 is elastomeric material.
Two hooks of described barb 4 are symmetrical, and size is identical.
Described burr 3 with between burr 3 to follow closely distance on bar 2 equal.
In the process of nail, can make to compare effort when just having started impact owing to being provided with barb 4, need to get hold of dynamics, nail is when idle, and due to the particularity of its design, nail tip can not upward, use safety.
The head of a nail 1 simplicity of design, there is no corner angle, can not surprisingly scratch, and time idle, nail tip can not be upward, after adopting said structure, convenient boring on cement wall, can be fixed with the soft material in thumb pin sleeve by burr 3, safe handling, due to the use of barb 4, strengthen frictional force, stationarity is strong, can not loose or dislocation.
Above one embodiment of the present of invention have been described in detail, but described content being only preferred embodiment of the present invention, can not being considered to for limiting practical range of the present invention.All equalizations done according to the present patent application scope change and improve, and all should still belong within patent covering scope of the present invention.
Claims (4)
