[0026] Also includes:

[0027] A laser pen 12 is arranged inside the support column 3, and a mounting groove 11 is arranged between the laser pen 12 and the support column 3, and the top of the mounting groove 11 is in an open form;

[0028] A positioning top plate 9 is arranged above the corner of the laser die body 2, and a reflective glass 14 is arranged on the lower surface of the positioning top plate 9, and the reflective glass 14 is bonded and connected to the positioning top plate 9;

[0029] The laser outlet 8 is arranged at a corner of the laser die body 2 , and the laser outlet 8 runs through the laser die body 2 .

[0030] See also Figure 1, connecting frames 10 are provided on both sides of the lower end of the positioning top plate 9, and the connecting frames 10 and the positioning top plate 9 are an integrated structure. The connecting frames 10 support the positioning top plate 9, and form a height difference with the laser outlet 8, which is convenient for personnel to check. Positioning is performed through the effect of laser reflection, which is simple and convenient, and it is easy to detect in time when offset, thereby improving convenience and positioning accuracy. The laser generated by the laser pen 12 is irradiated through the laser outlet 8 to the reflective glass 14 on the lower surface of the positioning top plate 9. When the reflective glass 14 at the four corners is bright, it means that the positioning is good. When offset, the laser is blocked and loses brightness, so that the offset occurs in time and re-positioning is needed.

[0031] See also Figure 2 A limiting groove 13 is provided on the inner bottom surface of the mounting groove 11, and the laser pen 12 is inserted into the inner wall of the limiting groove 13, which plays a limiting protection effect, avoids shaking, deflection and tipping, and improves positioning accuracy.

[0035] Working principle: When in use, the connecting frame 10 is fixed to the laser cutting mold body 2 by means of the fixing plate 15 and the threaded fastener 16, the positioning top plate 9 is aligned with the laser outlet 8, and the laser pen 12 is placed in the limiting groove 13 inside the supporting column 3 to play a limiting protection effect, avoid shaking, offset and tipping, and improve the positioning accuracy. Then the laser cutting mold body 2 is placed on the supporting column 3 at the upper end of the positioning base 1, and the laser outlet 8 at the corner of the laser cutting mold body 2 is aligned with the opening of the mounting groove 11 of the supporting column 3. The laser generated by the laser pen 12 is irradiated through the laser outlet 8 to the reflective glass 14 on the lower surface of the positioning top plate 9. When the reflective glass 14 at the four corners is bright, it means that the positioning is good. When the offset occurs, the laser is blocked and the brightness is lost, so that the offset occurs in time and repositioning is required. Then the connecting handle 17 is inserted into the handle slot 18 to fix the positioning base 1 and the laser cutting mold body 2. Positioning is performed by the effect of laser reflection, which is simple and convenient, and it is easy to detect the offset in time, thereby improving convenience and positioning accuracy.
