Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0032] Reference Figure 1-Figure 2 and Figure 5 The utility model provides an embodiment of a slitting device for grooving in construction, comprising a blade 1 for grooving and slitting in construction. A dust removal mechanism 3 is provided on the outside of the blade 1 to prevent dust from flying when the device is slitting. An adjustment mechanism is provided on the rear side of the dust removal mechanism 3 to adjust the depth of the slit of the blade 1. The adjustment mechanism comprises a mounting plate 6, a handle 7, an adjustment member 5 and a base plate 4. The bottom of the base plate 4 is fixedly connected to a universal roller 41, and the number thereof is multiple, for assisting the movement of the device when in use. The handle 7 is fixedly connected to the top of the mounting plate 6 for easy use and gripping by the user. The bottom surface of the mounting plate 6 is fixedly connected to a motor 2 for driving the blade 1. A rotating shaft 11 is passed through and fixedly connected to the middle of the blade 1 for cooperating with the connection between the blade 1 and the motor 2. The rotating shaft 11 is fixedly connected to the output end of the motor 2.

[0033] Furthermore, the number of adjusting parts 5 is two, and the adjusting part 5 includes a hollow column 51, which is used to cooperate and connect various components. The bottom of the hollow column 51 is fixedly connected to the base plate 4, which is used to cooperate and connect various components. The upper part of the hollow column 51 is rotatably connected with an adjusting sleeve 52, which is used to adjust the lifting and lowering of the stud 53, thereby adjusting the depth of the cutting seam of the blade 1. The middle part of the adjusting sleeve 52 is threadedly connected with a stud 53, which is used to cooperate and adjust the distance between the mounting plate 6 and the base plate 4. The stud 53 is slidably connected to the hollow column 51, and the top of the stud 53 is fixedly connected to the mounting plate 6.

[0034] See also Figure 3-Figure 4 The dust removal mechanism 3 includes a shell 31, which is used to cover the blade 1 and collect flying dust while ensuring safety in use. It is used to connect the various components. The rotating shaft 11 passes through the shell 31 and is rotatably connected to the shell 31. The shell 31 is fixedly connected to the mounting plate 6 for connecting with the adjustment mechanism. The lower part of the shell 31 is fixedly connected to a telescopic sleeve 32, which can be made of rubber or other materials. It can be stacked and telescopic to cooperate with cutting slots of different depths. The left and right parts of the shell 31 and the telescopic sleeve 32 are both provided with a control part 33 for controlling the extension and retraction of the telescopic sleeve 32, which is used to cooperate with limiting the position of the bottom ring 321.

[0035] The cam 332 is fixedly mounted on the rear edge of the cam 331 and is used to lock the cam 332 in the cam 331 position.

[0036] Working principle: When in use, according to the required slit depth, rotate the adjustment sleeve 52, and the adjustment sleeve 52 will drive the stud 53 connected to it to move, thereby adjusting the distance between the mounting plate 6 and the bottom plate 4 to control the degree of slit cutting by the blade 1, and then rotate the screw 332 according to the position of the bottom plate 4 so that the screw 332 drives the telescopic sleeve 32 outside it to move, thereby adjusting the position of the bottom ring 321 connected to it, so that the bottom ring 321 adjusts the telescopic condition of the telescopic sleeve 32, so that the bottom ring 321 can fit the building surface when slit cutting, so that the telescopic sleeve 32 can produce the slit when the blade 1 is slit. The dust chips are covered. After the adjustment is completed, the user holds the handle 7 with his hand, places the device at the position where the slitting is required, turns on the dust suction device, and allows the dust suction device to suck and clean the dust chips generated during the slitting through the dust removal pipe 312. Then, the motor 2 is turned on, and the motor 2 will drive the blade 1 to rotate through the rotating shaft 11. The blade 1 will then cut the position where the building needs to be slit. The handle 7 is driven by the hand to drive the entire device to adjust the position of the slit. When the device moves, the ball 322 on the bottom ring 321 and the universal roller 41 on the bottom plate 4 will assist the device in moving its position.
