[0022] This section will describe in detail the specific embodiments of the utility model. The preferred embodiments of the utility model are shown in the accompanying drawings. The purpose of the accompanying drawings is to supplement the description of the text part of the specification with graphics, so that people can intuitively and vividly understand each technical feature and the overall technical solution of the utility model, but it cannot be understood as a limitation on the protection scope of the utility model.

[0023] Reference Figure 1-4 The utility model discloses a sawing angle adjustment device for a circular saw blade of a table saw machine, which includes a workbench 1 and a protective cover 3. A circular saw blade 2 is arranged on the workbench 1. Two L-shaped blocks 4 are fixedly connected to the outer surface of the protective cover 3. A handle 5 is fixedly connected to the outer surface of the protective cover 3. There are two handles 5 and they are distributed front and back. The protective cover 3 is located on one side of the circular saw blade 2. The lower surface of the protective cover 3 contacts with the workbench 1, and the lower surface of the L-shaped block 4 contacts with the workbench 1.

[0024] The fixed structure 14 includes a concave block 6, a limiting rod 7, a connecting block 8, a screw rod 9 and a slider 10. The lower surface of the concave block 6 is fixedly connected to the workbench 1, the side surface of the limiting rod 7 is fixedly connected to the concave block 6, the inner surface of the connecting block 8 is rotatably connected to the limiting rod 7, the side surface of the connecting block 8 is fixedly connected to the screw rod 9, the inner surface of the slider 10 is threadedly connected to the screw rod 9, the outer surface of the screw rod 9 is movably connected to the L-shaped block 4, the upper surface of the L-shaped block 4 is fixedly connected to the limiting block 12, the number of the limiting blocks 12 is multiple and distributed in a rectangular array, the L-shaped block 4 is provided with a connecting groove 13, the outer surface of the screw rod 9 is movably connected to the connecting groove 13, the end of the screw rod 9 away from the connecting block 8 is fixedly connected with an anti-dropping block 11, the side surface of the slider 10 is in contact with the L-shaped block 4, the limiting rod 7 passes through the connecting block 8, the side surface of the connecting block 8 is in contact with the concave block 6, and the number of the fixed structures 14 is two and distributed on the left and right.

[0025] Working principle: Under the action of the protective cover 3, the circular saw blade 2 on the workbench 1 can be protected to prevent objects in the outside world from touching the circular saw blade 2. When the circular saw blade 2 needs to be used, the slider 10 is rotated to move the slider 10 on the screw rod 9. When the moved slider 10 is no longer in contact with the L-shaped block 4, and the moved slider 10 will not be affected by the limit block 12. After the slider 10 is flipped, the screw rod 9 is flipped, so that the flipped screw rod 9 drives the connecting block 8, the slider 10 and the anti-slip block 11 to flip with the limit rod 7 on the concave block 6 as the center axis. When the flipped screw rod 9 is separated from the connecting groove 13, the fixing of the protective cover 3 is released, and the protective cover 3 can be removed from the workbench 1, and then the handle 5 is lifted upwards, so that the protective cover 3 can be removed from the workbench 1, and then it can be properly When the circular saw blade 2 is used normally and needs to be protected, the protective cover 3 is placed back on the workbench 1 and covers the circular saw blade 2, and the screw rod 9 is aligned with the connecting groove 13, and then the screw rod 9 is flipped in the opposite direction. When the flipped screw rod 9 enters the connecting groove 13, the slider 10 is rotated in the opposite direction to move the slider 10 on the screw rod 9. When the moved slider 10 contacts the L-shaped block 4, the protective cover 3 can be fixed to avoid accidentally touching the protective cover 3 and causing the protective cover 3 to move, so that the protective cover 3 can always protect the circular saw blade 2. At the same time, under the action of the limit block 12, the stability of the screw rod 9 can be improved to prevent the slider 10 from detaching from the L-shaped block 4 and the screw rod 9 from detaching from the connecting groove 13. Moreover, under the action of the anti-detachment block 11, the slider 10 can be prevented from detaching from the screw rod 9.
