[0026] The embodiment of the present invention relates to a portable line projection instrument fixed on an exterior wall nail, such as Figure 1-4 As shown, it includes a hanging plate 1, a supporting plate 2 and a line-casting instrument 9, the hanging plate 1 and the supporting plate 2 are in an L-shaped plate structure as a whole, a plurality of leveling screws 7 are installed side by side on the upper end of the supporting plate 2, the leveling screws 7 are arranged vertically, the upper ends of the leveling screws 7 are inserted into the bottom of the line-casting instrument 9, the leveling screws 7 are screwed with a leveling knob 6, the line-casting instrument 9 is placed on the leveling knob 6, and the line-casting instrument 9 is supported by the plurality of leveling knobs 6, and a level bubble 10 is arranged on the upper part of the line-casting instrument 9;

[0027] The front end of the hanging plate 1 is located behind the line-casting instrument 9 and is provided with a hollow area 5. The lower part of the line-casting instrument 9 is provided with a plurality of horizontal line-casting holes 11 evenly arranged around the circumference. The upper part of the line-casting instrument 9 is provided with a plurality of vertical line-casting holes 12 evenly arranged around the circumference. A centering observation hole 8 is provided in the middle of the front end of the line-casting instrument 9 and is perpendicular to the hollow area 5.

[0028] The bottom of the line-casting instrument 9 is provided with a socket for inserting the leveling screw 7. The inner wall of the socket cooperates with the leveling screw 7 to achieve a guiding effect, so that the line-casting instrument 9 can move up and down. In order to prevent the line-casting instrument 9 from slipping out, a nut can be screwed on the upper end of the leveling screw 7 to limit the highest upward position of the line-casting instrument 9. The leveling knob 6 is not only used to support the line-casting instrument 9, but also used to limit the lowest downward position of the line-casting instrument 9.

[0029] like Figure 1 to Figure 3 As shown, a leveling knob 6 is provided on the leveling screw 7 below the line caster 9, and the leveling knob 6 can be freely rotated on the leveling screw 7 to adjust its horizontal position. The line caster 9 is leveled by the three leveling knobs 6. The leveling knob 6 is generally used for fine adjustment. When making a large adjustment, the line caster 9 can be lifted up first, and after the three leveling knobs 6 are adjusted, the line caster 9 can be placed on the leveling knob 6.

[0030] like Figure 1 to Figure 3As shown, a centering observation hole 8 is provided in the middle of the line projection instrument 9, and the centering observation hole 8 is perpendicular to the wall. A hollow area 5 is provided on the hanging plate 1. The intersection of rays emitted from the horizontal line projection hole 11 and the vertical line projection hole 12 can be observed through the centering observation hole 8. The intersection of rays is projected into the hollow area 5. The position of the intersection of rays and the wall reference point is observed in the centering observation hole 8, so as to judge whether the position of the rays meets the requirements.

[0031] The hanging plate 1 and the supporting plate 2 are integrally made of L-shaped galvanized steel plates. The hanging plate 1 and the supporting plate 2 can be integrally formed or welded together.

[0032] There are three leveling screws 7 in total, and the three leveling screws 7 are arranged in an equilateral triangle.

[0033] The front end of the hanging plate 1 is located on both sides of the line-casting instrument 9, and each column of vertical hanging holes 3 has three vertical hanging holes 3. The front end of the hanging plate 1 is located between the two columns of vertical hanging holes 3 and is equipped with a horizontal hanging hole 4, and the horizontal hanging hole 4 is located above the line-casting instrument 9; vertical hanging holes 3 and horizontal hanging holes 4 are set on the hanging plate 1, and the function of the hanging holes is to firmly fix the hanging plate 1 to the wall by tools such as screws; the vertical hanging holes 3 and horizontal hanging holes 4 are both long through holes, so that the hanging plate 1 can be adjusted up, down, left and right within a certain range.

[0034] The hollow area 5 is a rectangular through hole, and the centering observation hole 8 is a circular through hole.

[0035] The line projector of the present invention adopts a finished ray projector, and its internal structure is consistent with the mature ray projectors on the market. The line projector 9 is a laser line projector.

[0036] Method of use of the present invention:

[0037] First, place the hanging board 1 close to the wall, and translate the hanging board 1 so that the reference point of the wall is in the hollow area 5.

[0038] Then turn on the line-casting instrument, the rays emitted from the horizontal line-casting hole 11 and the vertical line-casting hole 12 form an intersection, observe the positions of the ray intersection and the reference point through the centering observation hole 8, and translate the hanging plate 1 to make the reference point overlap with the ray intersection.

[0039] Then use screws to fix the hanging plate 1 firmly to the wall, observe the position of the spirit level 10, rotate the leveling knob 6 to level the projection instrument according to actual needs, and after leveling, observe from the centering observation hole 8 whether the position of the ray intersection and the reference point meets the requirements, and make fine adjustments according to actual needs.

[0040] In the description of the present invention, it is necessary to understand that the directions or positional relationships indicated by directional words such as "front, back, up, down, left, right", "lateral, vertical, perpendicular, horizontal" and "top, bottom" are usually based on the directions or positional relationships shown in the drawings. They are only for the convenience of describing the present invention and simplifying the description. Unless otherwise specified, these directional words do not indicate or imply that the devices or elements referred to must have a specific direction or be constructed and operated in a specific direction. Therefore, they cannot be understood as limiting the scope of protection of the present invention. The directional words "inside and outside" refer to the inside and outside relative to the contours of each component itself.

[0041] For ease of description, spatially relative terms such as "above", "above", "on the upper surface of", "above", etc. may be used here to describe the spatial positional relationship between a device or feature and other devices or features as shown in the figure. It should be understood that spatially relative terms are intended to include different orientations of the device in use or operation in addition to the orientation described in the figure. For example, if the device in the accompanying drawings is inverted, the device described as "above other devices or structures" or "above other devices or structures" will be positioned as "below other devices or structures" or "below other devices or structures". Thus, the exemplary term "above" may include both "above" and "below". The device may also be positioned in other different ways (rotated 90 degrees or in other orientations), and the spatially relative descriptions used here are interpreted accordingly.

[0042] In addition, it should be noted that the use of terms such as "first" and "second" to limit components is only for the convenience of distinguishing the corresponding components. If not otherwise stated, the above terms have no special meaning and therefore cannot be understood as limiting the scope of protection of the present invention.

[0043] The above is a detailed introduction to a portable line-casting instrument fixed on an exterior wall nail provided by the present application. Specific examples are used in this article to illustrate the principles and implementation methods of the present application. The description of the above embodiments is only used to help understand the method of the present application and its core idea; at the same time, for general technical personnel in this field, according to the idea of ​​the present application, there will be changes in the specific implementation method and application scope. In summary, the content of this specification should not be understood as a limitation on the present application.
