[0004] To achieve the above purpose, the utility model provides the following technical solution: a gypsum board ceiling gap rear slotting device, which is used to cut an eight-shaped groove on the surface of the gypsum board, comprising:

[0005] Fixed structure.

[0006] A cutting structure is arranged on the fixing structure and is used for cutting the paper-faced gypsum.

[0007] Preferably, the fixing structure includes a hand piece, and a fixing threaded rod arranged on the hand piece for connecting the cutting structure, and a limiting threaded rod arranged on the hand piece for limiting the cutting structure, and the fixing structure is used to fix the cutting structure.

[0008] Preferably, the number of the fixing threaded rod and the limiting threaded rod is two, and the two fixing threaded rods and the limiting threaded rods are respectively arranged on both sides of the handpiece, one side is used to fix the first cutting piece, and the other side is used to fix the second cutting piece.

[0009] Preferably, four connecting holes are provided on the hand piece, and the four connecting holes are used to connect the two fixed threaded rods and the limiting threaded rod.

[0010] Preferably, the cutting structure comprises a first cutting member arranged on the fixing structure, and a second cutting member arranged on the fixing structure, and the cutting structure is used for cutting the splayed groove.

[0011] Compared with the prior art, the beneficial effects of the utility model are: the paper-faced gypsum board ceiling gap rear grooving device is easy to obtain materials and simple to make. All the required making materials are common materials on the market and do not require special procurement. In addition, it is simple to operate, highly practical, universal in use, easy to construct, and improves labor efficiency. BRIEF DESCRIPTION OF THE DRAWINGS

[0020] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0021] like Figure 1-2 As shown, the utility model provides a technical solution: a post-grooving device for gypsum board ceiling gaps, which is used to cut an eight-shaped groove 7 on the surface of the gypsum 6, including: a fixing structure and a cutting structure, the cutting structure is arranged on the fixing structure, and is used to cut the gypsum 6.

[0022] like Figure 3-4The fixing structure includes a hand piece 1, which is made of hot-dip galvanized sheet. The hand piece 1 is an open quadrilateral. Four connecting holes are opened on the hand piece 1. The sizes of the four connecting holes match the sizes of the fixed threaded rod 5 and the limiting threaded rod 4. The inner side of the connecting hole is provided with a thread that engages with the outer thread of the fixed threaded rod 5 and the limiting threaded rod 4. The four connecting holes are used to connect the two fixed threaded rods 5 and the limiting threaded rod 4, and the fixed threaded rod 5 provided on the hand piece 1 for connecting the cutting structure. The fixed threaded rod 5 is used to penetrate the first cutting piece 2 and the second cutting piece 3 and connect with the connecting holes, so as to connect the first cutting piece 2, the second cutting piece 3 and the hand piece 1. The two fixing threaded rods 5 and the limiting threaded rods 4 are connected in a row, and the number of the fixing threaded rods 5 and the limiting threaded rods 4 is two. The material of the fixing threaded rods 5 and the limiting threaded rods 4 is hot-dip galvanized bolts and nuts. The two fixing threaded rods 5 and the limiting threaded rods 4 are respectively arranged on both sides of the handpiece 1, one side is used to fix the first cutting piece 2, and the other side is used to fix the second cutting piece 3, as well as the limiting threaded rod 4 arranged on the handpiece 1 for limiting the cutting structure. The limiting threaded rod 4 is arranged on the rear side of the first cutting piece 2 and the second cutting piece 3 to block the first cutting piece 2 and the second cutting piece 3 to prevent the first cutting piece 2 and the second cutting piece 3 from rotating backward and offsetting when cutting. The fixed structure is used to fix the cutting structure.

[0023] The cutting structure includes a first cutting piece 2 arranged on the fixed structure, and a second cutting piece 3 arranged on the fixed structure. The first cutting piece 2 is connected to the front side of the second cutting piece 3, but the tip of the first cutting piece 2 and the tip of the second cutting piece 3 coincide with each other, ensuring that the splayed groove 7 can be accurately cut. The material of the first cutting piece 2 and the second cutting piece 3 is a 0.7 mm thick utility blade, and the cutting structure is used to cut the splayed groove 7.

[0024] In summary, in this embodiment, the first cutting piece 2 and the second cutting piece 3 are fixed on both sides of the hand piece 1 by fixing the threaded rod 5, and then the limiting threaded rod 4 is installed on the hand piece 1 to limit the first cutting piece 2 and the second cutting piece 3, and then the hand piece 1 is pressed obliquely and longitudinally into the gypsum 6, and moves along the gap of the gypsum 6 to remove the waste of the gypsum 6, and check the depth and quality of the splayed groove 7.

[0025] Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the appended claims and their equivalents.
