[0016] 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.

[0017] Embodiment 1: Refer to Figures 1-3 , a building wall grooving device, including a base 4, a motor 2 fixedly connected to the base 4, a rotating shaft 8 rotatably connected to the output shaft of the motor 2 through a bearing, an abutting block 9 fixedly connected to the rotating shaft 8, a connecting edge 10 fixedly connected to the abutting block 9, a plurality of saw wheels 7 sleeved on the connecting edge 10, the plurality of saw wheels 7 being fixed by a fixing mechanism, driving the saw wheels 7 to move through a moving device, the saw wheels 7 rotating to groove, and by adjusting the number of saw wheels 7, the width of the groove can be adjusted during grooving, so as to be adjusted according to the actual needs of accommodating wires, improving the applicability of the device.

[0018] The fixing mechanism includes a threaded rod 11, a nut 12 threadedly connected to the threaded rod 11, a plurality of connecting columns 14 fixedly connected to the nut 12, a fixing ring 13 fixedly connected to the plurality of connecting columns 14, the fixing ring 13 abutting against the saw wheel 7 to fix the saw wheel 7. When the saw wheel 7 needs to be disassembled or installed, by rotating the nut 12, the nut 12 is disassembled, and thus the fixing ring 13 is removed to change the number of saw wheels 7 on the connecting edge 10.

[0019] The locking thread direction of the nut 12 is opposite to the rotation direction of the motor 2, and the nut 12 will be tightened more and more due to inertia, ensuring the connection tightness between the nut 12 and the threaded rod 11.

[0020] A fixing frame 15 is fixedly connected to the base 4, and a protective shell 1 is fixedly connected to the fixing frame 15. The protective shell 1 covers the saw wheel 7. The fixing frame 15 is rotatably connected to the rotating shaft 8 through a bearing. By adopting the protective shell 1, a protective effect is achieved, which is beneficial to the safety of grooving.

[0021] A handle 5 is fixedly connected to the base 4 for easy grasping.

[0022] Embodiment 2: In Embodiment 1, when grooving, the depth of grooving is fixed, that is, the depth at which the saw wheel 7 cuts in. Refer to Figure 3 , as another preferred embodiment of the present invention, on the basis of Embodiment 1, two threaded columns 3 are threadedly penetrated and connected to the base 4. Both of the two threaded columns 3 are rotatably connected with abutting plates 6 through bearings. By rotating the threaded columns 3, the positions of the abutting plates 6 can be adjusted. When the abutting plates 6 abut against the wall, the depth at which the saw wheel 7 cuts into the wall body will be changed, so as to open grooves with different depths.

[0023] When in use: By rotating the nut 12, the nut 12 is disassembled, so that the fixing ring 13 is removed, and the number of saw wheels 7 on the connecting edge 10 is changed. Then, when the nut 12 is rotated again, the fixing ring 13 abuts against the saw wheel 7. The fixing ring 13 and the abutting block 9 fix the saw wheel 7. Then, the moving device starts the motor 2 for cutting.

[0024] The above is only a 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 should be covered within the protection scope of the present invention.
