DETAILED DESCRIPTION

[0020] The following will be combined with 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 of 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] Embodiment 1

[0022] See also Figure 1 - Figure 4 A wood cutting machine with adjustable cutting size includes a base 1, a fixed shaft 2 is fixedly connected inside the base 1, a clamping seat 3 is rotatably connected outside the fixed shaft 2, a hexagon socket bolt 4 is threadedly connected inside the clamping seat 3, an arc groove 5 for matching with the hexagon socket bolt 4 is opened inside the base 1, a limiting nut 6 is threadedly connected outside the hexagon socket bolt 4, a threaded rod 7 is threadedly connected inside the clamping seat 3, a push plate 8 is rotatably connected to one end of the threaded rod 7, and a fixed head 9 is fixedly connected to the other end of the threaded rod 7.

[0023] Specifically: when it is necessary to adjust the cutting size and angle of the wood, use a hexagonal wrench to loosen the hexagonal bolt 4. After the hexagonal bolt 4 is rotated, the gap between the limit nut 6 and the base 3 is increased, so that the base 3 can be moved. When the base 3 moves, it drives the hexagonal bolt 4 to slide inside the arc groove 5, thereby changing the direction of the wood on the top of the base 3. After the adjustment is completed, rotate the hexagonal bolt 4 to fix the base 3 on the top of the base 1.

[0024] Furthermore, a movable groove 10 is opened inside the base 1, and a movable block 11 is slidably connected inside the movable groove 10. Slide rods 12 are symmetrically slidably connected inside the movable groove 10, and one end of each slide rod 12 is fixedly connected to the movable block 11, and a spring 13 is sleeved on the outside of each slide rod 12. The other end of the two slide rods 12 away from the movable block 11 is fixedly connected to a mounting seat 14.

[0025] Specifically: the fixed head 9 is rotated, and the fixed head 9 drives the threaded rod 7 to rotate. When the threaded rod 7 rotates, the push plate 8 is driven to move, and the push plate 8 clamps the wood, thereby completing the clamping and limiting of the wood, which can meet the needs of cutting wood of different specifications and has strong adaptability.

[0026] Embodiment 2

[0027] Based on Example 1, in this embodiment, the top of the mounting seat 14 is fixedly connected to a fixing seat 15, the inside of the fixing seat 15 is rotatably connected to a damping shaft 16, the outside of the damping shaft 16 is rotatably connected to a damping block 17, the outside of the damping block 17 is fixedly connected to a protective shell 18, the inside of the protective shell 18 is fixedly connected to a motor 19, the driving end of the motor 19 is fixedly connected to a transmission shaft 20, and the outside of the transmission shaft 20 is fixedly connected to an active synchronous wheel 21.

[0028] Specifically: during the cutting process, some wood is larger in size, and the cutting disc 24 cannot complete the cutting operation at one time, so the cutting disc 24 needs to be moved and cut, and the handle 26 is moved. The handle 26 drives the protective shell 18 to move, and the protective shell 18 drives the damping block 17 to rotate. The damping block 17 and the damping shaft 16 are used in conjunction to limit the position of the cutting disc 24, and the cutting disc 24 can be suspended as needed. When the damping block 17 moves, it drives the damping shaft 16 to move, and when the damping shaft 16 moves, it drives the fixed seat 15 to move, and when the fixed seat 15 moves, it drives the mounting seat 14 to move, and when the mounting seat 14 moves, it drives the slide bar 12 to slide, and when the slide bar 12 slides, it drives the movable block 11 to move and squeeze the spring 13. The spring 13 gives the user a certain resistance to facilitate better control of the cutting. After the cutting is completed, the spring 13 rebounds and resets to assist the user in retracting the cutting disc 24.

[0029] Furthermore, the protective shell 18 is rotatably connected to an internal shaft 22 away from the active synchronous wheel 21, and the external part of the rotating shaft 22 is fixedly connected to a driven synchronous wheel 23, and the driven synchronous wheel 23 is connected to the active synchronous wheel 21 through a synchronous belt, one end of the rotating shaft 22 extends to the outside of the protective shell 18 and is fixedly connected to a cutting disc 24, a protective cover 25 is installed on the outside of the cutting disc 24, and a handle 26 is fixedly connected to the outside of the protective shell 18.

[0030] Specifically: when it is necessary to cut the wood, the motor 19 is started, and the motor 19 drives the transmission shaft 20 to rotate. When the transmission shaft 20 rotates, the active synchronous wheel 21 is driven to rotate. When the active synchronous wheel 21 rotates, the driven synchronous wheel 23 is driven to rotate through the synchronous belt. When the driven synchronous wheel 23 rotates, the rotating shaft 22 is driven to rotate. When the rotating shaft 22 rotates, the cutting disc 24 is driven to rotate. The protective cover 25 can protect the cutting disc 24 and prevent wood chips from splashing. The user presses the handle 26, and the handle 26 drives the cutting disc 24 to move downward, so that the wood can be cut.

[0031] 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.
