DETAILED DESCRIPTION OF THE EMBODIMENTS

[0019] Next, the technical solutions in the embodiments of the present utility model will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all of the embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present utility model.

[0020] Please refer to Figures 1 to 4 In the embodiment of the present utility model, a hole punching positioning device for construction engineering includes a positioning plate 1. An outwardly protruding pressing plate 2 is integrally formed on the outer periphery of the positioning plate 1. A guiding mechanism is installed at one end of the positioning plate 1, and the guiding mechanism is used to limit the moving position of a drilling head 9. The guiding mechanism includes a guiding column 3 fixedly connected to one end of the positioning plate 1. An anti-detachment portion 4 is integrally formed at the end of the guiding column 3 away from the positioning plate 1. A moving plate 5 is axially slidably connected to the outer wall of the guiding column 3. A connecting spring 6 is fixedly connected between the positioning plate 1 and the moving plate 5, and the connecting spring 6 is sleeved on the guiding column 3. A replacement mechanism is rotatably installed at the center of the moving plate 5, and the replacement mechanism is used to limit drilling heads 9 of different sizes.

[0021] In this embodiment: First, find the center of the hole to be punched by measurement. Then, according to the diameter of the hole to be punched, select a drilling head 9 of the corresponding size, and connect the drilling head 9 of the corresponding size to the output end of the drill gun. Then, select a docking plate 8 that matches the outer diameter of the drilling head 9, and then install and limit the docking plate 8 through the replacement mechanism;

[0022] After that, make the center of the inner circumference of the positioning plate 1 coincide with the measured center of the hole, and make the end of the positioning plate 1 away from the guiding column 3 fit against the wall, and apply sufficient pressing force to the pressing plate 2 with the hand to limit the positioning plate 1 on the wall;

[0023] After that, push the drill gun to move. The drill gun pushes the drilling head 9 to move until the drilling head 9 contacts the wall. In this process, the drill gun pushes the moving plate 5 to move, and the moving plate 5 compresses the connecting spring 6. After the drilling head 9 contacts the wall, start the drill gun, and the drill gun drives the drilling head 9 to rotate to realize the hole punching operation on the wall.

[0024] Please pay special attention to Figure 3 and Figure 4 The replacement mechanism includes a rotating plate 7 rotatably installed at the center of the moving plate 5. The rotating plate 7 is in a ring structure, and four insertion slots 12 are equidistantly arranged on the inner circumference of the rotating plate 7. The inner circumference and one end of the insertion slot 12 are both in an open structure. A docking plate 8 is detachably connected to the inner wall of the insertion slot 12. An insertion plate 10 that is inserted into the insertion slot 12 is integrally formed on the outer periphery of the docking plate 8. The replacement mechanism further includes moving slots 13 opened inside the rotating plate 7 and located on both sides of the insertion slot 12. One end of the moving slot 13 is communicated with the inner cavity of the insertion slot 12. A return spring 14 is fixedly installed at one end of the inner wall of the moving slot 13. The other end of the return spring 14 is fixedly connected to a limiting shaft 15 that penetrates into the inner cavity of the insertion slot 12. The end of the limiting shaft 15 located in the inner cavity of the insertion slot 12 is in a hemispherical structure. Hemispherical grooves 11 that match the hemispherical portions of the limiting shaft 15 are opened on both sides of the insertion plate 10.

[0025] In this embodiment: Select a docking plate 8 that matches the drill bit 9 of the corresponding size, align the outer circumference of the docking plate 8 with the inner circumference of the rotating plate 7, and align the insertion plate 10 with the insertion slot 12. Then, push the docking plate 8. The docking plate 8 drives the insertion plate 10 to insert into the insertion slot 12. When the insertion plate 10 contacts and presses against the hemispherical end of the limit shaft 15, the limit shaft 15 moves in the moving slot 13 under the force, and the moving limit shaft 15 presses against the return spring 14 until the limit shaft 15 completely enters the moving slot 13. When the insertion plate 10 completely enters the insertion slot 12, at this time, the hemispherical groove 11 is aligned with the hemispherical end of the limit shaft 15. At this time, the return spring 14 resets, and the reset return spring 14 pushes the hemispherical end of the limit shaft 15 to snap into the inner wall of the hemispherical groove 11, realizing the limitation of the docking plate 8 at the current position. This method can quickly install or replace the docking plate 8 with different inner diameters.

[0026] Please refer specifically to Figure 3 , the inner diameter of the docking plate 8 matches the inner diameter of the drill bit 9.

[0027] In this embodiment: The inner diameter of the docking plate 8 limits the corresponding drill bit 9, which can enable the drill bit 9 to move along the axial direction and prevent the drill bit 9 from shifting during the advancing process.

[0028] The above is only the preferred specific embodiment of the present invention, but the protection scope of the present invention is not limited thereto. Any person skilled in the art within the technical scope disclosed by the present invention, according to the technical solution of the present invention and its inventive concept, makes equivalent replacements or changes, and all should be covered within the protection scope of the present invention.
