Embodiment

Be described in detail below in conjunction with the embodiment of accompanying drawing the utility model.

Embodiment 1:

Fig. 1 is the front view of the embodiment 1 of the utility model, and Fig. 2 is the vertical view of Fig. 1, and Fig. 3 is the left view of Fig. 1; In conjunction with Fig. 1,2,3 shown, the laser measurement slide calliper rule of the utility model comprise blade 1; One end of blade 1 is provided with a circular hole 11; Laser marking device 3 is embedded in this circular hole 11, and laser marking device 3 comprises that one is arranged on the laser focusing knob 4 of its bottom, and the battery cover that the is arranged on laser marking device 3 tops switch 5 of holding concurrently; One numeral is installed on the blade 1 shows chi frame 2; Blade 1 can show chi frame 2 move left and right with respect to numeral; The upper and lower track 12 that respectively is provided with of blade 1; Numeral shows that the top and the bottom, bottom surface of chi frame 2 respectively are provided with the rail groove (not shown) that the track 12 with blade 1 adapts, and blade 1 can show move left and right on the chi frame 2 in numeral through the cooperation of track 12 and rail groove.

Numeral shows that the bottom surface of chi frame 2 is provided with a reference seat 6, and reference seat 6 shows that with numeral chi frame 2 adopts the detachable bayonet socket to be connected or screw connects; The middle part of reference seat 6 is provided with a circular hole 61, and this circular port 61 is a datum hole.

Present embodiment can use is measuring one to another or hole central projection distance between the two; Concrete use-pattern is: the circular hole 61 at the middle part of reference seat 6 is enclosed within on the measured axle; Move left and right blade 1; The laser cross curve of getting until laser marking device 3 overlaps with the measured axle or the center in hole, adjusts the laser focusing knob simultaneously, makes that laser rays is thin and clear; And then accurately move blade, at this moment can read the accurate projection distance of centre distance between the two through numeral demonstration chi frame 2.

General slide calliper rule are to be used for certain the fixedly distance of operation or measurement of parameter, so the utility model adopts hole and axle sleeve dress to realize the accurate setting of benchmark, and the embodiment of back mention spool with the accurate setting that realizes benchmark that cooperates in hole.If the diameter of the hole of benchmark or axle distance changes; Can select the diameter of corresponding datum hole or axle to replace; Therefore the utility model has designed dismountable reference seat, and datum hole that is provided with on the reference seat or axle adopt no diameter to select so that enough replacements to be provided.
