Description

Technical Field

[0001] The present application relates to the technical field of jigsaws, and in particular to a dust-absorbing jigsaw. Background Art

[0002] A jigsaw is an electric tool mainly used for cutting curves on materials such as wood, plastic, and metal. Its working principle is to achieve cutting by driving the saw blade to move back and forth through a motor. The rotational motion of the motor is converted into a linear reciprocating motion of the saw blade through a series of transmission mechanisms. The saw blade is usually narrow and thin with sharp teeth to ensure cutting accuracy and efficiency.

[0003] Upon checking the announcement number: CN207289043U, a curved saw is disclosed, and this technology discloses "including: a saw blade, a motor for driving the saw blade to cut a workpiece, a casing for accommodating the motor, a bottom plate formed with a bottom plate plane, a reciprocating rod for realizing power transmission between the motor and the saw blade, and a surface light source device for lighting; the reciprocating rod extends in a direction perpendicular to the bottom plate plane; the casing has a lower end close to the saw blade and an upper end away from the saw blade in the direction along which the reciprocating rod extends; the surface light source device is installed to the lower end of the casing; the surface light source device includes: a light guide element and a light emitting element, the light guide element is formed with a light emitting surface for emitting light and a light incident surface for introducing light into the light guide element, the light emitting element is arranged at the light incident surface of the light guide element; the light emitting element emits light toward the light incident surface, and other technical solutions have the technical effects that the curved saw can perform shadowless lighting in a dim environment."

[0004] Regarding the above-mentioned related technologies, the inventor believes that most of the existing jigsaws are complex in design and inconvenient to operate. The complex internal structure will increase the maintenance cost of the jigsaw and make it more prone to local damage. The single-layer shell of most jigsaws has limited protection ability for the internal structure, and the convenience of use is poor. In addition, most of the existing jigsaws cannot absorb the debris generated by cutting, which is not environmentally friendly, and the flying debris may affect the quality of the cutting process. Therefore, a dust-absorbing jigsaw is needed to solve the above problems. Utility Model Content
