DETAILED DESCRIPTION

[0024] 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.

[0025] See also Figure 1-Figure 5 The utility model provides a technical solution: a panel saw that is convenient for adjusting the angle of a cutting tool, comprising: a body 1 and a threaded rod 16, a motor 2 is arranged inside the body 1, a saw blade 3 is fixedly connected to the output end of the motor 2, and a limit plate 4 is arranged on the top of the body 1.

[0026] The side of the machine body 1 away from the limit plate 4 is movably connected with a protective plate 5 through a rotating shaft, and a lever 6 is fixedly connected to one side of the protective plate 5. A first connecting rod 7 is movably connected to one side of the lever 6 through a rotating shaft, and a tension spring 8 is fixedly connected between the first connecting rod 7 and the lever 6. A handle 9 is provided on one side of the first connecting rod 7, and a second connecting rod 10 is fixedly connected to one side of the handle 9. The outer side of the second connecting rod 10 is slidably connected to a driving gear 11 through a slider, and a limiting groove matching the second connecting rod 10 and the slider is provided inside the driving gear 11; one side of the driving gear 11 A limit block 12 is fixedly connected to the side of the body 1, and an annular groove is opened inside the body 1 for the limit block 12 to rotate; the outer side of the driving gear 11 is meshingly connected with the driven gear 13, one side of the driven gear 13 is fixedly connected with a worm 14, and the outer side of the worm 14 is meshingly connected with a worm wheel 15; one side of the worm wheel 15 is fixedly connected to a connecting shell 25, the inner side of the connecting shell 25 is fixedly connected to the motor 2, and the two sides of the worm wheel 15 are movably connected to the body 1 through a rotating shaft, the driving gear 11 and the driven gear 13 form a meshing transmission structure, and the protective plate 5 forms a rotating structure with the body 1 through the rotating shaft.

[0027] When the protective plate 5 is rotated and contacts the handle 9, the first connecting rod 7 will move the handle 9, and the handle 9 can pull the second connecting rod 10 to slide inside the driving gear 11. When the protective plate 5 is fully rotated and opened, the handle 9 will also be brought out of the body 1. At this time, the second connecting rod 10 can be driven to rotate by the handle 9, and the second connecting rod 10 can be driven to mesh with the driven gear 13 through the outer slider. When the driven gear 13 rotates, it can drive the worm 14 to mesh with the worm wheel 15, so that the connecting shell 25 is rotated, and the angle of the saw blade 3 on one side of the connecting shell 25 is also changed. At this time, the wooden board can be cut at different angles.

[0028] Since the number of teeth of the driving gear 11 is smaller than that of the driven gear 13, the handle 9 will drive the worm 14 to perform a deceleration motion when it rotates, so that the connecting shell 25 rotates more slowly, thereby improving the adjustment accuracy. At the same time, the force required for the handle 9 to rotate will also be reduced accordingly, so that the angle of the saw blade 3 can be adjusted more easily. After the adjustment is completed, the protective plate 5 is closed by rotating.

When the lever 6 contacts the handle 9, it will continue to push the handle 9. When the handle 9 is completely entered into the body 1, the first connecting rod 7 will pass over the handle 9. At this time, the tension spring 8 will be reset, and the first connecting rod 7 will also be pulled to rotate and reset. In this way, the angle of the panel saw can be easily adjusted through the above operation.

[0029] See also Figure 1 , Figure 2 , Figure 3 and Figure 6 A threaded rod 16 is threadedly connected to the top of the body 1 through a fixed block, one end of the threaded rod 16 is movably connected to the limit plate 4 through a bearing, and one end of the threaded rod 16 is fixedly connected to a first bevel gear 17; the outer side of the first bevel gear 17 is meshedly connected to the second bevel gear 18, one side of the second bevel gear 18 is fixedly connected to a large gear 19, and one side of the large gear 19 is movably connected to the limit plate 4 through a rotating shaft; the outer side of the large gear 19 is meshedly connected to a small gear 20, one side of the small gear 20 is fixedly connected to a fan blade 21, one end of the fan blade 21 is movably connected to the limit plate 4 through a bearing, and a ball 22 is rollingly connected to the bottom of the limit plate 4; the outer side of the ball 22 is rollingly connected to the upper end surface of the body 1, and the interior of the limit plate 4 is movably connected to a roller 23 through a rotating shaft, and a scale mark 24 is provided on the upper end surface of the body 1, and the first bevel gear 17 and the second bevel gear 18 constitute a meshing transmission structure.

[0030] In specific implementation, when cutting the wood board, a panel saw is required, which can quickly cut the board. In order to limit the cutting size of the wood board on the panel saw, the threaded rod 16 is threadedly transmitted with the machine body 1 by rotating the threaded rod 16, and the threaded rod 16 will drive the limit plate 4 to move. The scale mark 24 at the bottom of the limit plate 4 can accurately grasp the moving distance of the limit plate 4, which is convenient for adjusting the position of the limit plate 4. The ball 22 at the bottom of the limit plate 4 can reduce the friction during movement. When the threaded rod 16 rotates, it will drive the first The bevel gear 17 is meshed with the second bevel gear 18, and the second bevel gear 18 can drive the large gear 19 to rotate. When the large gear 19 rotates, it will mesh with the small gear 20 to rotate the fan blades 21. Since the number of teeth of the large gear 19 is greater than that of the small gear 20, the fan blades 21 can be driven to accelerate. When the fan blades 21 rotate rapidly, the wood chips on the bottom scale mark 24 will be blown away to prevent the wood chips from affecting the observation of the scale mark 24. In this way, the position of the limit plate 4 can be easily adjusted through the above operation, so as to facilitate the limitation of the processing size of the wooden board.

[0031] To sum up: when using a panel saw that is easy to adjust the tool angle, first start the motor 2 to drive the saw blade 3 to rotate, then place the wooden board on the table top of the body 1, and press against the limit plate 4, and then push the wooden board to move.
