Description

Technical Field

[0001] This utility model relates to the field of jigsaw technology, and more specifically, to a jigsaw with an auxiliary cutting device. Background Technology

[0002] A jigsaw is a commonly used electric cutting tool. It uses a motor to drive the saw blade to perform high-speed reciprocating linear motion, thereby enabling the cutting of various materials such as wood, metal, and plastic. Because of its narrow and short saw blade, it is very suitable for curved cutting and processing of complex shapes. It is widely used in woodworking, decoration and other fields. A traditional jigsaw usually includes a housing, a motor installed in the housing, an output shaft driven by the motor to perform reciprocating motion, and a saw blade connected to the output shaft.

[0003] To improve cutting stability and precision, existing technologies typically include a pressure frame around the saw blade at the bottom of the jigsaw base. This frame is used to press the workpiece surface firmly during the cutting process, providing an additional stable support point for the tool. This effectively prevents the saw blade from jumping at the start of the cut and reduces the machine body's forward tilting or lateral swaying during the cutting process, thus ensuring the flatness and verticality of the cut to a certain extent.

[0004] Existing jigsaws with auxiliary cutting devices can provide uniform and stable downward pressure when cutting flat plates, ensuring smooth cutting. However, when cutting curved workpieces, they cannot fit well with the curved surface, resulting in pressure concentration and a significant reduction in the support area. This unstable support can cause the jigsaw to tilt, vibrate, or even suddenly slip during the cutting process, causing the cutting path to deviate from the predetermined trajectory. This not only seriously affects the cutting accuracy and processing quality but also poses certain safety hazards. Therefore, we propose a jigsaw with an auxiliary cutting device.

[0005] The purpose of this invention is to provide a jigsaw with an auxiliary cutting device to address the aforementioned shortcomings of the prior art.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a jigsaw, including a saw body, a handle and a pressure frame, wherein magnetic suction components are provided on both sides of the pressure frame of the jigsaw, and an elastic frame is provided on the outer side wall of the saw body of the jigsaw.

[0007] A curved edge is set at the bottom of the elastic frame, including an edge piece. The edge piece can be engaged with a magnetic component and held in place by the magnetic component. Several sliding holes are opened on the surface of the edge piece, and an elastic moving part is slidably connected to the inner sidewall of the sliding hole.

[0008] The elastic moving part includes a universal ball seat elastically connected to the bottom of the side piece, and the inner side wall of the universal ball seat is rotatably connected with a ball.

[0009] The lever-pressing structure can be used in conjunction with an elastic frame to drive the curved edge pressing up and down.

[0010] As a further description of the above technical solution: the magnetic suction assembly includes an L-shaped frame, and a magnetic suction piece is installed on the top of the inner sidewall of the L-shaped frame.

[0015] The jigsaw with an auxiliary cutting device provided by this utility model, as described above, has the following beneficial effects:

[0016] This utility model discloses a jigsaw with an auxiliary cutting device. When cutting workpieces with curved surfaces, the end of the lever pressing structure can be pinched upwards, causing the first end of the lever pressing structure to descend. The pressure bar and pressure frame press down on the curved surface edge, allowing the elastic moving part to contact and adapt to the contour around the cutting point of the curved workpiece. The ball bearings facilitate the movement of the elastic moving part on the surface of the curved workpiece while continuously adapting to the contour of different cutting points. This ensures that the jigsaw fits the surface of the curved workpiece more closely during cutting, reducing displacement and shaking. Furthermore, it does not require electrical equipment to drive it, saving resources and facilitating operation. This solves the problem that existing jigsaws with auxiliary cutting devices have poor auxiliary cutting effects when cutting non-curved materials. Attached Figure Description

[0029] To enable those skilled in the art to better understand the technical solution of this utility model, the present utility model will be further described in detail below with reference to the accompanying drawings.

[0030] Please see Figures 1-4 This utility model provides a technical solution: including a jigsaw 1, including a saw body, a handle and a pressure frame, magnetic suction components 2 are provided on both sides of the pressure frame of the jigsaw 1, and an elastic frame 4 is provided on the outer wall of the saw body of the jigsaw 1.

[0031] In another embodiment of the present invention, preferably, the magnetic suction component 2 includes an L-shaped frame 201, and a magnetic suction piece 202 is installed on the top of the inner side wall of the L-shaped frame 201.

[0032] Curved edge 3 is set at the bottom of elastic frame 4 and includes edge piece 301. Edge piece 301 can cooperate with magnetic component 2 and be attracted by magnetic component 2. Several sliding holes 302 are opened on the surface of edge piece 301. Elastic moving part 303 is slidably connected to the inner side wall of sliding hole 302.

[0033] The elastic movable component 303 includes a universal ball seat 3033 elastically connected to the bottom of the side piece 301, and a ball bearing 3034 is rotatably connected to the inner side wall of the universal ball seat 3033.

[0034] In another embodiment of this utility model, a slide rod 3031 is fixed to the top of the universal ball seat 3033. The slide rod 3031 is slidably connected to the slide hole 302. A top piece 3035 is fixed to the top of the slide rod 3031. A spring A3032 is sleeved on the outer wall of the slide rod 3031. The spring A3032 is located between the side piece 301 and the universal ball seat 3033, providing an upward elastic restoring force for the universal ball seat 3033 and the ball 3034.

[0035] In another embodiment of this utility model, the elastic frame 4 includes a mounting plate 401 fixed to the outer wall of the saw body of the jigsaw 1. A spring B402 and a guide assembly 403 are mounted on the bottom of the mounting plate 401. An edge piece 301 is fixed to the bottom of the spring B402 and the guide assembly 403. The entire curved edge 3 can be elastically raised and lowered relative to the jigsaw 1. When the pressing lever pressing structure 5 is stopped, the spring B402 resets and drives the curved edge 3 to rise and reset, so that the pressing frame of the jigsaw 1 presses the workpiece.

[0036] The lever pressing structure 5 can cooperate with the elastic frame 4 to drive the curved surface pressing edge 3 to rise and fall, and is used to drive the curved surface pressing edge 3 to move downward against the elastic force of the spring B402.

[0037] In another embodiment of this utility model, the lever pressing structure 5 includes two sets of lever bodies 501. The middle part of the lever body 501 is rotatably connected to the outer wall of the saw body of the jigsaw 1. The ends of the two sets of lever bodies 501 are connected to each other through a handle 502. A spring C503 is installed on the outer wall of the handle 502. The top of the spring C503 is installed at the bottom of the handle of the jigsaw 1. The spring C503 is connected to the bottom of the handle of the jigsaw 1, providing a restoring force for the lever mechanism, so that the handle 502 remains in a low position when it is not squeezed.

[0038] In another embodiment of the present invention, a pressure strip 504 is hinged to the first end of the lever body 501, and a pressure frame 505 is slidably connected to the bottom of the pressure strip 504. The bottom of the pressure frame 505 is disposed on the top of the side piece 301.

[0039] Working principle: This embodiment provides a jigsaw with an auxiliary cutting device. When in use...

[0040] When cutting on curved sheet metal, the operator holds the handle of the jigsaw 1 and pinches the handle 502 upwards. The lever pressing structure 5 moves accordingly, the tail end of the lever body 501 rises upwards, the spring C503 is compressed and shortened, and its head end presses downwards. Through the pressure bar 504 and the pressure frame 505, the curved pressing edge 3 is pressed downwards, so that it overcomes the elastic force of the spring B402 and moves downwards. At the same time, it disengages from the magnetic attraction of the magnetic attraction component 2 and places the jigsaw 1 on the workpiece. The ball bearings 3034 at the bottom of the multiple elastic moving parts 303 are in close contact with the workpiece surface under the pressure of the spring A3032. Since each elastic moving part 303 can extend and retract independently, the ball bearings 3034 make it easy for the elastic moving part 303 to move on the surface of the curved workpiece while continuously adapting to the contour of different cutting points of the curved workpiece. This makes the jigsaw 1 fit more closely with the surface of the curved workpiece during cutting, reducing displacement and shaking.

[0041] After the cutting work is completed, release the handle 502. Under the combined action of spring C503 and spring B402, the lever pressing structure 5 and the curved pressing edge 3 automatically reset. The magnetic suction component 2 magnetically attracts the edge piece 301 through the magnetic suction piece 202, keeping the curved pressing edge 3 in the current position, reducing shaking, so that when the jigsaw 1 cuts on the flat workpiece, it can be smoothly carried out by the pressing frame without the need for electrical equipment drive, saving resources and facilitating operation.

[0042] The foregoing description only illustrates certain exemplary embodiments of the present invention. Undoubtedly, those skilled in the art can modify the described embodiments in various ways without departing from the spirit and scope of the present invention. Therefore, the above drawings and descriptions are illustrative in nature and should not be construed as limiting the scope of protection of the claims of the present invention.
