Description

A kind of laser marker

Technical field

The utility model relates to the instrument that a kind of horizontal vertical is measured, and relates in particular to a kind of laser marker that has locating device.

Background technology

Measuring appliance is indispensable instrument in building decorating industry.Widely used in the past is line of ink marker box, the line of ink marker is exposed outside, easily contaminated, when the traction line of ink marker is measured the snap the line operation, because line of ink marker blotting is inhomogeneous, the infull phenomenon of snap the line ink marks is often arranged, when reclaiming the line of ink marker, need handle to shake line of ink marker axle, the working costs effort, very inconvenient, and the resultant error of measuring is bigger.Along with the progress in epoch, the raising of people's living standard, line of ink marker box obviously can not satisfy present people's needs.Many enterprises have brought into use laser marker in the present architectural decoration, but these laser markers are difficult on floor or the soft operating surface and locate, and laser requires to use under highly stable state, and this has just influenced the accuracy of measuring.

Summary of the invention

Goal of the invention of the present utility model is in order to overcome the defective of above-mentioned prior art, a kind of laser marker to be provided, can simply and easily instrument be fixed on the operating surface, can making the result of measurement more accurate.

The novel technical scheme of this use is: a kind of laser marker, comprise level, support, base, generating laser and the locating device that is located on the base constitutes, and the locating device on the described base is made up of 2-3 draw point assembly;

Described draw point assembly is made up of knob, press button, spring and draw point, fixedlys connected with press button in the top of draw point, is provided with projection in the press button, and the press button below is provided with knob, is provided with spring and draw-in groove in the knob, and draw point passes the pin hole on spring and the base.

By the produced laser marker of technique scheme, be placed on the scope of operation of floor or softness, as long as press button can be fixed on base on the scope of operation to next pressure, thereby can regulate laser marker easily, this positioning device structure is simple, convenient and practical, have good use prospect.
