[0002] During building construction, it is usually necessary to groove the ground and discharge water pipes, gas pipes, electric wire pipes, optical fiber cables, etc. into the grooves. When grooving for small-scale construction, people usually use a pneumatic hammer to complete it. When the pneumatic hammer strikes to groove, in order to ensure the accuracy of grooving, it is necessary to first cut a seam on the ground or wall. After cutting the seam, the pneumatic hammer is used to hammer, so that a suitable groove is cut out on the ground or wall. The existing grooving method is usually to hold a cutting device to cut the building. Since the machine is heavy, it is easy to cause the cut seam to bend, affecting the subsequent use of the groove, and at the same time, it is also easy to reduce the efficiency of cutting the seam.

[0031] In order to enable those skilled in the art to better understand the technical solution of the present invention, the present invention will be described in detail below with reference to the accompanying drawings. The description of this part is only exemplary and explanatory, and should not have any restrictive effect on the protection scope of the present invention.
[0032] Such as Figures 1-5As shown in the figure, a cutting seam device for building construction grooving includes an installation bracket 1 and a protective cover 3. A hand-held handle 11 is installed at the end of the installation bracket 1, and an angle sensor 12 and a display screen 13 with a single-chip microcomputer are installed inside the installation bracket 1. A driving motor 2 is installed on one side of the installation bracket 1 away from the hand-held handle 11, and a speed reducer 21 is connected to the output end of the driving motor 2. One end of the speed reducer 21 away from the driving motor 2 is connected to a cutting blade 22. The protective cover 3 is installed at one end of the installation bracket 1 away from the hand-held handle 11, and mounting plates 31 are installed at the upper and lower ends of the protective cover 3. One end of the mounting plate 31 is installed with a guide plate 32, and the other end of the mounting plate 31 is installed with a guide post 34. A moving roller 33 is installed on the outside of the guide plate 32, and a return spring 35 is sleeved on the outside of the guide post 34. During the moving cutting seam process, the moving roller 33 reduces the friction when the device moves. During the cutting seam, the angle sensor 12 detects the angle of the device, and the result is displayed through the display screen 13 with a single-chip microcomputer. When the angle deviates, the user can adjust the device according to the displayed angle information, thereby ensuring the straightness of the cutting seam and the cutting efficiency. A bearing is installed at the connection between the cutting blade 22 and the protective cover 3. Through the bearing, the rotation of the cutting blade 22 can be made more stable, thereby ensuring the cutting seam effect of the cutting blade 22. The mounting plate 31 and the protective cover 3 are installed in a snap-fit sliding structure, and the mounting plate 31 and the installation bracket 1 are arranged parallel to each other. The snap-fit sliding structure can make the mounting plate 31 slide smoothly along the protective cover 3, thereby facilitating the mounting plate 31 to contract towards the protective cover 3 under the push of the guide plate 32. The parallel arrangement can make the sliding of the mounting plate 31 more reliable and stable. Both sides of the guide plate 32 are inclined. The inclined setting can increase the passing performance of the guide plate 32, thereby facilitating the user to drive the device to move. A bearing is installed at the connection between the moving roller 33 and the guide plate 32. The moving rollers 33 are symmetrically arranged about the center line of the guide plate 32, and the moving rollers 33 and the guide plate 32 are arranged parallel to each other. During the moving process, the moving rollers 33 on the guide plate 32 can effectively reduce the friction when the guide plate 32 moves with the device, thereby facilitating the cutting seam of the device. The symmetrically arranged moving rollers 33 can ensure the stability of the guide plate 32 during movement, and the parallel arrangement can make the rotation of the moving rollers 33 more stable. The guide post 34 and the return spring 35 are arranged with their axes coinciding. The return spring 35 with the axes coinciding can be pushed to contract under the extrusion of the mounting plate 31, and then the return spring 35 can conveniently and reliably push the mounting plate 31 to reset after the device is used. The driving motor 2 and the installation bracket 1 are fixed by a flange and bolts. Through the flange and bolts, the connection between the driving motor 2 and the installation bracket 1 can be made more reliable and firm.
[0033] The working principle of the present utility model is as follows: When using this device, turn on the angle sensor 12 and the display screen 13 with a single-chip microcomputer. The user holds the handheld handle 11 and places the device on the area to be cut. At this time, the moving roller 33 contacts the building. Turn on the drive motor 2, and the drive motor 2 drives the cutting blade 22 to rotate through the reducer 21 to cut the ground. As the drive motor 2 rotates, the pressing device descends to cut a slit in the building. When cutting the slit, the guide plate 32 squeezes the mounting plate 31 and slides along the protective cover 3, thereby squeezing the return spring 35 to make the guide plate 32 contract towards the protective cover 3, which facilitates the cutting blade 22 to cut a slit in the building. At this time, pull the device to move. During the movement, the moving roller 33 on the guide plate 32 can effectively reduce the friction when the guide plate 32 moves with the device, which facilitates the slit cutting of the device. When cutting the slit, the angle sensor 12 detects the angle of the device, and the result is displayed through the display screen 13 with a single-chip microcomputer. When the angle deviates, the user can adjust the device according to the displayed angle information, thereby ensuring the straightness of the slit and the efficiency of the slit cutting.
