[0004] The utility model solves its technical problems by adopting the following technical solutions:

[0005] A circular saw blade bracket device includes a main bracket. A disc bracket with a saw blade over-travel groove is rotatably arranged in the middle of the main bracket. And an adjustment angle display scale for displaying the angle is arranged on the side of the disc bracket. A power saw frame is hinged on the disc bracket, and a circular saw blade driven by an electric motor is arranged in the power saw frame.

[0006] Preferably, a limit guard plate is fixedly arranged on the upper end surface of the main bracket through bolts.

[0007] Preferably, a second threaded fastening knob is further connected to the limit guard plate. The lower end surface of the second threaded fastening knob abuts against the upper end surface of the disc bracket to fasten the disc bracket. When the second threaded fastening knob is loosened, the disc bracket can be rotated.

[0008] Preferably, a bottom frame is fixedly arranged on the disc bracket through bolts. A rotating handle is fixedly arranged at the lower end of the power saw frame, and the rotating handle is rotatably arranged in the bottom frame, so that the cutting angle of the circular saw blade can be changed, and the application range is wider. A first threaded fastening knob for locking the rotation angle of the rotating handle is connected to the tail end of the bottom frame.

[0009] Preferably, two limit bosses are further fixedly arranged on the power saw frame to limit the downward rotation angle of the power saw frame, to prevent the circular saw blade from hitting the main bracket beyond the saw blade over-travel groove, effectively ensuring the safety of the circular saw blade.

[0010] Preferably, extension support frames are inserted at both ends of the main bracket, and the extension support frames can be telescopically inserted into the main bracket. When the part to be cut is long, the extension support frames can be pulled out and the bent parts at the tails of the extension support frames can be used for support.

[0011] The advantages and positive effects of the present utility model are as follows: it can provide good support for long components to facilitate cutting, can adjust the position of the cutting line by rotating the disc bracket, and can handle diagonal cutting at any angle.

[0014] Figure 2 is a schematic structural diagram of the present utility model. DETAILED DESCRIPTION OF THE EMBODIMENTS

[0015] The present utility model will now be further described in detail with reference to the drawings. These drawings are all simplified schematic diagrams, only illustrating the basic structure of the present utility model in a schematic manner, and therefore only showing the components related to the present utility model.

[0016] The following further details the embodiments of the present utility model with reference to the drawings:

[0017] As Figure 1-2 shown, a circular saw blade bracket device of the present utility model includes a main bracket 11. A disc bracket 12 with a saw blade overrun groove 13 is rotatably provided in the middle of the main bracket 11. An adjustable angle display scale 14 for displaying the angle is provided on the side of the disc bracket 12. A power saw frame 17 is hinged on the disc bracket 12, and a circular saw blade 18 driven by an electric motor 16 is provided in the power saw frame 17.

[0018] Preferably, a limit guard plate 15 is fixedly provided on the upper end surface of the main bracket 11 by bolts.

[0019] Preferably, a second threaded fastening wrench 22 is further connected to the limit guard plate 15. The lower end surface of the second threaded fastening wrench 22 abuts against the upper end surface of the disc bracket 12 to fasten the disc bracket 12. When the second threaded fastening wrench 22 is loosened, the disc bracket 12 can be rotated.

[0020] Preferably, a bottom frame 19 is fixedly provided on the disc bracket 12 by bolts. A rotating handle 20 is fixedly provided at the lower end of the power saw frame 17, and the rotating handle 20 is rotatably arranged in the bottom frame 19, so that the cutting angle of the circular saw blade 18 can be changed, and the application range is wider. A first threaded fastening wrench 21 for locking the rotation angle of the rotating handle 20 is connected to the end of the bottom frame 19.

[0021] Preferably, two limiting bosses 23 are fixedly arranged on the electric saw frame 17 to limit the downward rotation angle of the electric saw frame 17, preventing the circular saw blade 18 from hitting the main bracket 11 beyond the saw blade overtravel groove 13, effectively ensuring the safety of the circular saw blade 18.

[0022] Preferably, extension support frames 10 are inserted at both ends of the main bracket 11, and the extension support frames 10 are telescopically inserted into the main bracket 11.
