[0022] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0023] Reference Figure 1 , Figure 3 and Figure 4 This utility model provides an embodiment of a wall drilling device for building construction, comprising an electric hammer body 1, a drill bit 2 for drilling is provided at the left end of the electric hammer body 1, a sleeve 5 is provided at the right end of the electric hammer body 1, connecting rods 7 are fixedly connected to both the front and rear ends of the sleeve 5, a U-shaped plate 8 is fixedly connected to the upper left end of the connecting rod 7, the lower side of the U-shaped plate 8 is tightly fitted with the upper left end of the electric hammer body 1, a movable rod 11 is movably provided inside the left end of the connecting rod 7, an adjusting groove 22 is provided on the outer side of the connecting rod 7, a slider 23 is movably provided inside the adjusting groove 22, and the end of the slider 23 is fixedly connected to the outer right end of the movable rod 11. A connecting ring 12 is fixedly connected to the top left end of the U-shaped plate 8. A rotating ring 13 is rotatably connected to the outer left end of the connecting ring 12. A protective cover 14 is fixedly connected to the left end of the rotating ring 13. A through hole 15 for the drill bit 2 to pass through is provided in the middle of the protective cover 14. A partition 16 is fixedly connected to the inner left end of the protective cover 14. A threaded ring 17 is threadedly connected to the outer left end of the protective cover 14. A support bar 18 is fixedly connected to the outer side of the threaded ring 17. A limiting ring 19 is fixedly connected to the middle of the U-shaped plate 8. A limiting rod 20 passes through the middle of the limiting ring 19. The left end of the limiting rod 20 is threadedly connected to the inside of the connecting ring 12. A spring 21 is provided on the outer left end of the limiting rod 20.

[0024] By adjusting the cooperation of the slide groove 22 and the slider 23, the position of the movable rod 11 within the connecting rod 7 can be adjusted, thereby changing the distance between the protective cover 14 and the wall. During operation, pressing the left end of the protective cover 14 against the wall can effectively block flying debris. The compressed spring 21 keeps the protective cover 14 in close contact with the wall during drilling. During drilling, by rotating the protective cover 14, the partition 16 is positioned below the drill bit 2. At this time, the dust generated during drilling is blocked and collected inside the protective cover 14. After drilling, the partition 16 can be moved upward by rotating the protective cover 14. At this time, the partition 16 no longer blocks the collected dust, making it easy to clean. The support bar 18 increases the contact area with the wall and can be used by the operator to determine whether the electric hammer body 1 and the drill bit 2 are perpendicular to the wall. The slider 23 moves inside the adjusting slide groove 22 to prevent the movable rod 11 from disengaging from the connecting rod 7. By rotating the limiting rod 20, it can be removed from the connecting ring 12.

[0025] Reference Figures 1-3 The upper right side of the electric hammer body 1 is provided with a first threaded hole 3, the upper side of the sleeve 5 is provided with a first fastener 6, the lower end of the first fastener 6 is threaded to the inside of the first threaded hole 3, the upper left side of the electric hammer body 1 is provided with a second threaded hole 4, the right side of the U-shaped plate 8 is fixedly connected with a fixing ear 9, the front and rear ends of the fixing ear 9 are provided with second fasteners 10, the lower end of the second fastener 10 is threaded to the inside of the second threaded hole 4.

[0026] By engaging the first fastener 6 with the first threaded hole 3, the sleeve 5 can be fixed to the outside of the right end of the electric hammer body 1. By engaging the second fastener 10 with the second threaded hole 4, the fixing ear 9 is fixed to the upper side of the electric hammer body 1. Thus, the U-shaped plate 8 and the connecting rod 7 are installed on the outside of the electric hammer body 1. The installation is convenient and the disassembly is simple.

[0027] Working principle: The first fastener 6 and the second fastener 10 are used to install the socket 5 and the connecting rod 7 on the outside of the electric hammer body 1. The spring 21 can push the connecting ring 12, so that the protective cover 14 and the support bar 18 installed at its end are in close contact with the wall. The contact between the protective cover 14 and the support bar 18 and the wall can be used to determine whether it is perpendicular to the wall. The movable rod 11 can slide left and right inside the connecting rod 7, so that the protective cover 14 can move left and right. The electric hammer body 1 is started to drive the drill bit 2 to rotate and drill a hole in the wall. As the drilling goes deeper, the movable rod 11 gradually goes deeper into the connecting rod 7. During drilling, the protective cover 14 always covers the outside of the drilling area to intercept the dust generated during drilling.

[0028] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features.
