[0014] The present invention provides an indoor decoration auxiliary wire groove opening device, which has the following beneficial effects:

[0015] (1) In the present invention, when the long board moves downward, the long board will drive the circular saw to move downward. When the circular saw moves downward, the circular saw will contact the ground. At this time, the circular saw will cut a wire groove on the ground. The distance the circular saw moves downward can be controlled by pressing the handle downward, so that the depth of the wire groove can be adjusted. The spring 1 can bear the weight of the circular saw disk, which can effectively prevent the circular saw from moving downward and causing damage to the ground when the worker's hand is separated from the handle. When the lever moves to the right to the rightmost end of the irregular long groove, the lever will be pushed upward by the elastic force of the spring 1. At this time, the lever will be stuck by the irregular long groove and the spring 1, and the height of the circular saw will be fixed. When the height of the circular saw is fixed, the depth of the ground cut by the circular saw will remain consistent, which can effectively prevent the worker from being unable to press the handle downward stably when cutting the ground, resulting in different depths of the wire groove cut by the circular saw, thereby affecting the later wire embedding.

[0016] (2) In this invention, the protective cover controls the distance the protective cover moves to the left according to the distance the circular saw moves downward, so that the protective cover can fit the circular saw more closely and effectively prevent the circular saw from falling off due to unexpected situations during operation, thereby causing the circular saw to bounce out. The nozzle sprays water at the cutting position of the circular saw, which can prevent the temperature of the circular saw from being too high and reduce the dust generated by the circular saw during the cutting process, thereby causing harm to the workers. When the circular saw cuts deeper, the nozzle will leak more. The nozzle controls the amount of water sprayed according to the distance the circular saw moves downward, thereby reducing the water consumption, preventing the ground from slipping, and reducing the difficulty of cleaning.

[0017] (3) In this invention, when the device needs to turn, the long rod will keep the rotation angles of the front and rear wheels consistent, which can facilitate the movement of the device. When the short rod moves along the arc surface of the arc block, the short rod will move to the middle part of the front and rear wheels. When the cross plate rotates, the cross plate will drive the wheels to correct, which can effectively prevent the wheels from tilting and causing the cut wire groove to shift. When the arc-shaped inclined plate moves, the arc-shaped inclined plate will contact the ground. At this time, the arc-shaped inclined plate will clear the obstacles in front of the wheels to prevent the wheels from pressing on the obstacles and shifting. BRIEF DESCRIPTION OF THE DRAWINGS

At this time, the lever 13 will be stuck by the irregular long groove and the spring 14, and the height of the circular saw 6 will be fixed. When the height of the circular saw 6 is fixed, the depth of the ground cut by the circular saw 6 will remain consistent, which can effectively prevent the worker from being unable to steadily press the handle 7 downward when cutting the ground, resulting in different depths of the wire grooves cut by the circular saw 6, which will affect the later wire embedding.
