Specific embodiment

It is the schematic diagram of the utility model as shown in Fig. 1 to Fig. 2, the utility model provides a kind of fixed drawing pin, by Eccentric structure is used in entire fixed drawing pin, structure is simple, and it is easily operated, and fall and be not easy to bounce, it is easy to use.

As shown in Figs. 1-2, in order to achieve the above object, the utility model adopts the following technical solution realizes, a kind of fixation Drawing pin, the fixed drawing pin include spike body 101, substrate 102；One end face of the spike body 101 and the substrate 102 One face is combined as a whole；The spike body 101 is located at one end and and the base plan for deviateing substrate center on the substrate 102 Vertically.

As shown in figures 3-8, the spike body 101 is located at the one end for deviateing substrate center on the substrate 102, understands shape in this way At eccentric structure.So-called eccentric structure includes but is not limited to following three kinds of situations, and one, including entirely fix in drawing pin gravity The structure that the heart and geometric center deviate；Two, it can also include: spike body 101 in the geometric center position for deviateing substrate 102 Structure；Three, it can also include that centered on substrate 102 when symmetrical figure, spike body 101 is set to the center of gravity for deviateing substrate 102 Position.For example, then in this configuration, fixing drawing pin from entirety when spike body 101 is located at the geometric center of substrate 102 Speech, geometric center and center of gravity are to be overlapped, and when fixed drawing pin falls from eminence, fixed drawing pin is easy to bounce, and falls It drops down onto and falls a little distant position apart from original.And the structure of the utility model is used, spike body 101 is located at the substrate The one end for deviateing substrate center on 102, causes the geometric center fixed drawing pin as a whole and center of gravity not same Position, when fixed drawing pin falls from eminence, it is not easy to bounce, convenient for finding the fixation drawing pin fallen；Preferably, when spike body 101 deviate the remoter of substrate center's deviation on the substrate 102, and effect is better.

The spike body 101 is vertebra body or cylinder or prismatoid, described logical since through-hole is arranged in the edge of workpiece The shape in hole is corresponding with the spike body 101 of the fixed drawing pin, it is preferable that the shape of spike body 101 is bullet or ladder Body, when that will fix drawing pin fixation workpiece, bullet or prismatoid are more convenient for through the through-hole on workpiece.

One end face of the spike body 101 is combined as a whole with a face of the substrate 102, and described is combined into one Body can be and spike body 101 and substrate 102 are sticked together；Or it is provided with hole on the substrate 101, the spike body 101 is embedding Enter in hole.

In addition, the shape of the substrate 102 is the irregular quadrilateral that regular quadrangle or four angles are circular arc.

Such as Fig. 3, shown in Fig. 4, when quadrangle of the shape using rule of the substrate 102, such as rectangle, spike body 101 are located on substrate 102 and deviate one end of substrate center and vertical with 102 plane of substrate, and spike body is in rectangular either end , eccentric structure can be formed between spike body 101 and substrate 102；In another example trapezoidal, spike body 101 is located on substrate 102 Deviate one end of substrate center and vertical with 102 plane of substrate, and preferably, be biased to one end of trapezoidal long side in substrate 102, This not only realize easily holds, and the advantages of easily looking for, as well as in the case where not influencing stress, saves materials.

As shown in Figure 5, Figure 6, when the shape of the substrate 102 uses four angles for the irregular quadrilateral of circular arc, such as Four angles are the rectangle of circular arc, spike body 101 be located on substrate 102 one end of deviation substrate center and with 102 plane of substrate Vertically, eccentric structure can be formed between spike body 101 and substrate 102, this shape is not easy to hurt hand, and in fixed workpiece When, it is also not easy to keep workpiece damaged, plays the role of protection.

In addition, the shape of the substrate 102 is triangle or three angles are the sealene triangle of arc.

As shown in fig. 7, the shape when the substrate 102 uses triangle, it is preferable that spike body 101 is located on substrate 102 Deviate one end of substrate geometric center and vertical with 102 plane of substrate, for example, one angle of triangle is set as apex angle, in addition two A angle is base angle, then spike body 101 is located at substrate 102 close to the one end at two base angles, and this not only realize easily holds, easily look for Target-seeking advantage saves materials as well as in the case where not influencing stress.

As shown in figure 8, the shape of the substrate 102 uses three angles for the sealene triangle of arc, it is preferable that spike Body 101, which is located on substrate 102, deviates one end of substrate geometric center and vertical with 102 plane of substrate, for example, by one, triangle Angle is set as apex angle, other two angle is base angle, then spike body 101 is located at substrate 102 close to the one end at two base angles, this shape It is not easy to hurt hand, and when fixed workpiece, is also not easy to keep workpiece damaged, plays the role of protection, meanwhile, also save Material has been saved, cost is reduced.

In addition, the shape of the substrate is ellipse.

When the shape of the substrate 102 is using ellipse, spike body 101 is located at deviation substrate geometric center on substrate 102 One end and vertical with 102 plane of substrate, eccentric structure can be formed between spike body 101 and substrate 102, this shape is not easy Hurt hand, and when fixed workpiece, is also not easy to keep workpiece damaged, plays the role of protection.

In addition, the spike body 101 is centrum or cylinder.

As shown in Fig. 2, Fig. 9, the spike body 101 can use cylinder or centrum, it is preferable that selection centrum works as selection When centrum, the upper bottom surface product of centrum is less than bottom area, is easy to passing through spike body 101 into the through-hole on workpiece.

In addition, the other end of the substrate 102 includes hand-held part, the hand-held part includes anti-skid bulge or antiskid groove.

The hand-held part includes anti-skid bulge or antiskid groove, is to facilitate to hold and play anti-skidding work when hand-held With.

In addition, the substrate 102 and spike body 101 are made of high-molecular compound, metal or alloy, the substrate 102 It is integrally formed with spike body 101.

The substrate 102 and spike body 101 are integrally formed, and integrated molding is for easy to process and substrate 102 and spike Connection between body is stronger.

Preferably, the spike body 101 is combined with the marginal portion of one end close to substrate 102.

It is combined using spike body with the marginal portion of one end close to substrate, is in order to hand-held more convenient.

In addition, the utility model also provides a kind of fixation device using above-mentioned fixed drawing pin, comprising: fixed drawing pin, work Part, workbench；For example, the workpiece is pcb board material.The edge of the workpiece is arranged through-hole, the shape of the through-hole with The spike body of the fixed drawing pin it is corresponding；For example, through-hole can be arranged at four angles of workpiece.

The above is only the preferred embodiment of the utility model only, is not intended to limit the utility model, all at this Made any modifications, equivalent replacements, and improvements etc., should be included in the utility model within the spirit and principle of utility model Protection scope within.
