BRIEF DESCRIPTION OF THE DRAWINGS

[0015] Figure 1 It is a front view schematic diagram of this embodiment;

[0016] Figure 2 yes Figure 1 Stereoscopic diagram;

[0017] Among them, there are a right-angle bar 1, a slider 1a, a lever 1b, a long strip 2, a limit portion 2a, a first laser 3, a green light 3a, a second laser 4, a blue light 4a, and a reference bar 5. DETAILED DESCRIPTION

[0018] like Figure 1 , Figure 2 As shown, this embodiment includes a right-angle bar 1 , a long bar 2 , a first laser 3 and a second laser 4 .

[0019] The long strip 2 passes through the right-angle end of the right-angle strip 1 in a plane, and divides the right angle of the right-angle strip 1 into two 45° angles. In other embodiments, the right-angle strip 1 and the long strip 2 are fixed, but in this embodiment, the right-angle strip 1 can slide back and forth on the long strip 2. Specifically, a slider 1a is provided at the right-angle end of the right-angle strip 1, and two right-angled strips are fixed at right angles to each other on both sides of the slider 1a. The slider 1a is provided on the long strip 2 and can slide back and forth on the long strip 2. In order to facilitate sliding, a lever 1b is also provided on the slider 1a in this embodiment, and the lever 1b can be used to pull the right-angle strip 1 to slide back and forth on the long strip 2.

[0020] The first laser 3 and the second laser 4 are both arranged on the strip 2. The first laser 3 and the second laser can slide back and forth on the strip 2 along the length direction of the strip 2. In this embodiment, a limiting portion 2a is provided at the end of the strip 2. Specifically, a stopper is provided at the end of the strip 2. The stopper can prevent the first laser 3, the second laser 4 and the right-angle strip 1 from sliding off the strip 2.

[0021] The first laser 3 and the second laser 4 can both emit two lasers, and the two lasers are respectively vertically hit on the two strips of the right-angle bar 1, that is, the two lasers emitted by the first laser 3 or the second laser 4 and the two strips of the second right-angle bar 1 form a rectangle. For the sake of distinction, the first laser 3 in this embodiment emits green light 3a and the second laser 4 emits blue light 4a. In other embodiments, the first laser 3 and the second laser 4 can also use other colors.

[0022] When drawing, it is only necessary to align the right-angle bar 1 with the horizontal line or vertical line of a certain view. The spacing between the first laser 3 and the second laser 4 of this embodiment on one strip of the right-angle bar 1 is equal to the spacing between the first laser 3 and the second laser 4 on the other strip of the right-angle bar 1, that is, the horizontal spacing in the left view is converted into the vertical spacing in the top view. When it is necessary to convert any horizontal spacing in the left view into the vertical spacing in the top view, it is only necessary to adjust the position of the first laser 3 and the second laser 4 on the strip 2.

[0023] Preferably, the present embodiment further provides a reference bar 5. The reference bar 5 is V-shaped, specifically, a 90° V-shape, and the corner end of the reference bar 5 is fixed on the long strip 2 and is located outside the right angle of the right-angled strip 1. The reference bar 5 can be rotatably connected to the long strip 2 or fixedly connected. When the fixed connection is adopted, the two strips constituting the reference bar 5 should be parallel to the two strips constituting the right-angled strip 1. The present embodiment adopts a rotatable connection. In the present embodiment, the V-shaped angle of the reference bar 5 is fixed, but in other embodiments, the V-shaped angle of the reference bar 5 can be set to any adjustable structure. The reference bar 5 adopts a foldable and unfoldable structure for easy storage.

[0024] When in use, use the reference bar 5 to align with a horizontal boundary or a vertical boundary of the main view, rotate the long strip 2 to make the right-angle bar 1 coincide with a horizontal edge or a vertical edge of a certain view, and then slide and adjust the positions of the right-angle bar 1, the first laser 3, and the second laser 4 on the long strip 2 to convert a local horizontal spacing in the left view into a local vertical spacing in the top view.

[0025] In other embodiments, the reference strip 2 may be a strip, one end of which may be fixed to the strip 2 or rotatably connected to the strip 2. Although a strip does not have as wide an application range as the two strips in this embodiment, it can also satisfy the function of reference alignment.

[0026] Finally, it should be noted that the above embodiments are only used to illustrate the technical solution of the utility model, rather than to limit the protection scope of the utility model. Although the utility model has been described in detail with reference to the preferred embodiments, ordinary technicians in this field should understand that the technical solution of the utility model can be modified or replaced by equivalents without departing from the essence and scope of the technical solution of the utility model.
