Brief description). The laser module 5 is disposed at any one of the peripheral surfaces 23 of the body 2. The laser module 5 of the embodiment is vertically disposed in a vertical manner to be used against a vertical wall; the laser module 5 The three laser heads are arranged, and one end of each of the bases 11 is connected to each other and has a Y shape. The bases 11 are parallel to the same plane and have an angle of 120 degrees. The light source projectors are oriented toward the surroundings to illuminate the projectors of the respective light sources. The lines formed at the time are joined to form a closed laser frame pattern. When measuring, the second surface 122 can be closely attached to the wall surface, so that the laser frame pattern can be flat on the wall surface as a reference standard for thickness and flatness during construction.

The invention is characterized in that the design of the adjusting structure 14 is provided for the constructor to adjust the illumination angle of the light source projector, and can perform fine adjustment of the laser frame pattern; more specifically, when the laser head body 12 is assembled with the base 11, The first adjusting member 141 can be first screwed to the first locking hole 112. Then, the second adjusting member 142 is loaded and abutted on the assembly surface 111 (the order may be reversed); thereby, the screw head depth of the first adjusting member 141 can be used to control the laser head body 12 and the The distance between the base 11 and the tilt angle (as shown in FIG. 4 and FIG. 5) is to change the illumination angle of the light source projector to achieve the purpose of fine-tuning the illumination angle.

At the assembly surface 111, the second adjusting member 142 ensures that the distance between the laser head body 12 and the base 11 can be maintained at least at a distance (providing a support point), so that the first adjusting member 141 and the second adjusting member 142 are mutually connected. The pinning is formed to form a stable fixing effect, so that when both the first adjusting member 141 and the second adjusting member 142 are tightly fixed, an excellent fixing effect can be formed between the laser head body 12 and the base 11 so that The two cannot be separated or close together and can be maintained at a fixed angle. Improve the angle of the conventional laser head to easily shift the position, and ensure the smooth operation of the construction work.

In addition, the laser head body 12 is provided with a plurality of third locking holes 127, and each of the third locking holes 127 extends between the opening 125 and the side surface 123, and is screwed into each of the third locking holes 127. The locking member is provided with a third adjusting member 128. The third adjusting member 128 can enter and exit the opening 125 through the third locking hole 127 and abut against the lens column 131; thereby, the third adjusting member 128 on one side When the depth of the screw lock is increased and the screw depth of the third adjusting member 128 on the other side is reduced, the lens column 131 is slightly angularly deflected, and the angle of the lens column 13 is adjusted by using a screw-in locking method. Therefore, in addition to the angle adjustment of the laser head body 12 and the base 11, the invention can further adjust the angle of the lens column 13 to apply various usage conditions and requirements.

Furthermore, the laser head body 12 is further provided with two evasing grooves 129 at one end of the opening 125. The two evasing grooves 129 are respectively located at two sides of the lens column 13, and the two evasing grooves 129 The direction of the line is perpendicular to the direction of the line connecting the first surface 121 and the second surface 122. The dodging groove 129 is substantially in the form of a meandering groove. The lens column 13 protrudes from the two dodging grooves 129. One end of the opening 125; thereby, the dodging groove 129 helps to increase the range of the illumination angle of the lens column 13, and reduces the blocking interference caused by the laser head body 12 to the lens column 13, ensuring that the formed laser frame pattern can have High brightness and obvious visual effects.

Moreover, the lens column 13 is in a planar abutting surface 131 adjacent to one end of the second surface 122.
