Detailed description of the invention

In order to make the purpose of this utility model, technical scheme and advantage clearly understand, below in conjunction with drawings and Examples, prefix clamping device of the present utility model is further elaborated.Should be appreciated that specific embodiment described herein only in order to explain the utility model, and be not used in restriction the utility model.

As shown in Figure 1, a kind of prefix clamping device, comprises handle 1 and clamping part 2;

Handle 1 is fixedly connected with clamping part 2;

Clamping part 2 is arranged clamping hole 3;

Clamping hole 3 is set with prefix, and clamping part 2 is gripped by clamping hole 3 pairs of prefixs.

During use, prefix can be arranged in clamping hole 3, prefix is had the alignment work position, position of word by the hand-held handle 1 of operating personnel, and hammering prefix afterbody afterwards, completes mark work.Such operating personnel do not need directly to hold by prefix, thus avoid the phenomenon generation that hand is hindered in hammering, ensure that the safety of expression work is carried out, can also avoid firmly kicking the beam when there is hammering simultaneously, ensure the quality of mark, and structure is simple, with low cost.

More preferably, as a kind of embodiment of the present utility model, ejector pin 4 is comprised;

Clamping part 2 is arranged locating hole 5;

Locating hole 5 connects with the sidewall of clamping hole 3;

Ejector pin 4 is arranged on locating hole 5, and one end is connected with clamping part 2, and the other end is connected on the prefix in clamping hole 3.

Such ejector pin 4 can withstand on prefix through the sidewall of clamping hole 3, the state of prefix in clamping hole 3 can be made so more stable, firm, ensure that carrying out smoothly of mark work.

More preferably, as a kind of embodiment of the present utility model, plug screw 6 is also comprised;

Locating hole 5 arranges screw thread;

Plug screw 6 and locating hole 5 arrange screw thread match, for be threaded connection mode be arranged on locating hole 5;

Plug screw 6 is connected to one end of ejector pin 4, and then on the prefix that the other end of ejector pin 4 is connected in clamping hole 3.

Like this, by regulating plug screw 6 precession or back-out, the prefix in ejector pin 4 pairs of clamping holes 3 can be made to hold out against or unclamp, can conveniently prefix be fixed, and making more changing jobs of prefix become very easy.

More preferably, as a kind of embodiment of the present utility model, elastomeric element 7 is also comprised;

Elastomeric element 7 is arranged between plug screw 6 and ejector pin 4;

Plug screw 6 is connected to one end of ejector pin 4 by elastomeric element 7.

Wherein plug screw 6 can adopt polyurethane spring, but is not limited to this, also can be compression of metals spring etc.

Plug screw 6 is connected to one end of ejector pin 4 by elastomeric element 7, elastomeric element 7 can cushion the active force of plug screw 6 pairs of ejector pins 4, thus make the active force of ejector pin 4 pairs of prefixs remain on a suitable scope, avoid excessive the causing of the active force of ejector pin 4 pairs of prefixs to occur the damage of ejector pin 4 and prefix or the phenomenon of adhesion both occurring.

More preferably, as a kind of embodiment of the present utility model, handle 1 and clamping part 2 one-body molded.

Handle 1 and clamping part 2 can adopt metal material, as No. 45 steel or A3 steel etc., handle 1 and clamping part 2 one-body molded, be convenient to the making of this prefix clamping device, reduce cost of manufacture.

More preferably, as a kind of embodiment of the present utility model, clamping part 2 is arranged peep hole 8;

Peep hole 8 is suitable with the position of clamping hole 3, for observing working environment by peep hole 8, and then determines the operating position of prefix in clamping hole 3.

In mark work, operating personnel observe working environment (impression as identified) by peep hole 8, and the result arrived according to the observation is to adjust the operating position of prefix, the position of mark can be made so more accurate, thus the overall mark of control is neat, spacing is even, improves the quality of expression work.

Above embodiment makes the utility model have: reasonable in design, structure is simple, easy to use, can ensure that mark work safety carries out, and improve the advantage of the quality of mark work.

The above embodiment only have expressed several embodiment of the present utility model, and it describes comparatively concrete and detailed, but therefore can not be interpreted as the restriction to the utility model the scope of the claims.It should be pointed out that for the person of ordinary skill of the art, without departing from the concept of the premise utility, can also make some distortion and improvement, these all belong to protection domain of the present utility model.Therefore, the protection domain of the utility model patent should be as the criterion with claims.
