[0036] The cutting knife 201a can be used to cut plastic products to obtain the desired shape and size. The cutting plate 201b is provided with cutting grooves to facilitate the cutting knife to cut plastic products. When the cutting knife 201a is not needed, the cutting knife 201a can be moved to the bottom of the cutting plate 201b to protect the cutting knife 201a and extend the service life of the cutting knife 201a.

[0037] Specifically, the cutting member 201 further includes a moving plate 201c and a motor 201d. The motor 201d is fixed to one side of the cutting blade 201a, and the moving plate 201c is fixed to the bottom of the motor 201d.

[0038] By moving the movable plate 201c, the movable plate 201c drives the cutting knife 201a to move, so that the cutting knife 201a moves above the cutting plate 201b, thereby cutting the plastic products. The setting of the motor 201d can drive the cutting knife 201a to rotate, thereby cutting the plastic products.

[0039] Specifically, the cutting member 201 further includes a moving rod 201e and a moving frame 201f. The moving rod 201e is fixed to one side of the moving plate 201c, and the moving frame 201f is hinged to one end of the moving plate 201c.

[0040] The movable rod 201e is provided for the convenience of the user to hold. By moving the movable rod 201e, the movable plate 201c can be driven to move. The movable frame 201f is used to support the movable plate 201c to prevent the movable plate 201c from deflecting.

[0041] Specifically, the limiting member 202 includes a limiting frame 202a and a limiting block 202b. The limiting frame 202a is fixed to the bottom of the moving frame 201f, and the limiting block 202b is arranged on one side of the limiting frame 202a.

[0042] The limit frame 202a is provided with a limit groove corresponding to the limit block 202b, and the limit block 202b is engaged with the limit groove. After the moving rod 201e is moved to the specified position, in order to prevent the moving rod 201e from falling, the limit groove and the limit block 202b are engaged to prevent the moving rod 201e from falling.

[0044] One end of the torsion spring 202d is fixed to one side of the limit block 202b, and the other end is fixed to one side of the rotating column 202c. When it is necessary to release the limit on the moving rod 201e, the limit block 202b is moved. The movement of the limit block 202b can apply a torsional force to the torsion spring 202d, and the limit block 202b moves and separates from the limit groove, thereby releasing the limit on the moving rod 201e. After the moving rod 201e is moved to the specified position, the limit block 202b is released. At this time, the force of the rotation of the torsion spring 202d can drive the limit block 202b to re-engage with the limit groove, so as to limit the moving rod 201e again.

[0045] Specifically, the limiting member 202 further includes a fixing plate 202e, which is fixed to one side of the rotating column 202c, and the fixing plate 202e is fixed to the bottom of the moving rod 201e.

[0049] Specifically, the adjusting member 203 includes an adjusting rod 203a and a positioning block 203b. The adjusting rod 203a is fixed to one side of the moving frame 201f, and the positioning block 203b is hinged to one end of the adjusting rod 203a.

[0050] When it is necessary to cut the plastic products at different angles, the movable frame 201f is moved. The movement of the movable frame 201f can drive the adjustment rod 203a to move. When the movable frame 201f moves, the movable frame 201f can be supported by the setting of the adjustment rod 203a to prevent the movable frame 201f from shifting. At this time, the angle of the cutting knife 201a can be tilted to cut the plastic products at different angles. The positioning block 203b is fixed to the bottom of the cutting board 201b. The adjustment rod 203a can be supported by the setting of the positioning block 203b to prevent the adjustment rod 203a from shifting.

[0051] Specifically, the adjusting member 203 further includes an adjusting column 203c and an adjusting frame 203d. The adjusting column 203c is fixed to one side of the moving frame 201f. The adjusting frame 203d is sleeved on the outside of the adjusting column 203c. The adjusting frame 203d and the adjusting column 203c are movably connected.

[0052] When the movable rack 201f needs to be moved, the adjusting column 203c is moved, and the adjusting frame 203d is fixed to the bottom of the cutting plate 201b. A movable groove is provided on the adjusting frame 203d, and the adjusting column 203c slides in the movable groove. When the adjusting column 203c is moved, the movable rack 201f can be moved toward the movable groove through the guidance of the movable groove, so that the movable rack 201f can be tilted, so that the angle of the cutting knife 201a can be tilted, so that the plastic products can be cut at different angles.

[0053] Specifically, the adjusting member 203 further includes a positioning disk 203e and a movable sleeve 203f. The positioning disk 203e is sleeved on the outside of the adjusting column 203c. The movable sleeve 203f is sleeved on the outside of the adjusting column 203c. The movable sleeve 203f and the adjusting column 203c are threadedly connected.

[0054] After the angle of the cutting knife 201a is adjusted to the specified position, in order to prevent the cutting knife 201a from moving on its own, the adjusting column 203c needs to be limited. The movable sleeve 203f is rotated to make the movable sleeve 203f contact one side of the adjusting frame 203d, so that the adjusting column 203c can be limited. The positioning plate 203e is used to support the adjusting column 203c to prevent the adjusting column 203c from shifting.

[0055] When in use, when it is necessary to cut plastic products at different angles, the cutting knife 201a needs to be adjusted to the top of the cutting plate 201b, and the limit of the moving rod 201e needs to be released first, and the limit block 202b is moved. The movement of the limit block 202b can apply a torsional force to the torsion spring 202d, and the limit block 202b moves and separates from the limit groove, so that the limit of the moving rod 201e can be released, and then the moving rod 201e is moved, and the moving rod 201e drives the moving plate 201c. Move, the moving plate 201c moves the cutting knife 201a to move, so that the cutting knife 201a moves to the top of the cutting plate 201b. At this time, the moving plate 201c needs to be limited to prevent the moving plate 201c from falling by itself, and the limit block 202b is released. At this time, the force of the rotation of the torsion spring 202d can drive the limit block 202b to re-engage with the limit groove, so as to limit the moving rod 201e again, and then start the motor 201d, and the motor 201d drives the cutting knife 201a to rotate so that the plastic product can be cut.

[0056] When the angle of the cutting knife 201a needs to be adjusted, the adjusting column 203c is moved, and the adjusting column 203c slides in the moving groove. When the adjusting column 203c is moved, it can slide in the moving groove, and the movable frame 201f can be moved toward the moving groove through the guidance of the moving groove, so that the movable frame 201f can be tilted, and the tilting of the movable frame 201f can make the angle of the cutting knife 201a tilt. After the angle of the cutting knife 201a is adjusted, the adjusting column 203c needs to be limited to prevent the adjusting column 203c from moving by itself, and the movable sleeve 203f is rotated to make the movable sleeve 203f contact with one side of the adjusting frame 203d, so that the adjusting column 203c can be limited, and then the motor 201d is started, and the motor 201d drives the cutting knife 201a to rotate, so that the plastic product can be cut at different angles.
