Description

Technical Field

[0001] The utility model relates to the technical field of electric saws, in particular to a multifunctional electric saw. Background Art

[0002] A multi-function saw is a power tool that combines multiple cutting functions and features. Typically, it can be used to cut wood, metal, or other materials, with different types of cutting tools (such as circular saw blades, chain saw blades, etc.) and adjustment mechanisms to suit different work needs and materials. The design of a multi-function saw usually includes cutting depth and angle adjustment, safety protection devices, efficient electric motor and transmission system, and portable or fixed working platform.

[0003] The mechanical structure of the traditional multifunctional electric saw is used to enable it to efficiently cut a variety of materials such as wood and metal. It includes the following structures: In terms of adjustment system, a more accurate and easy-to-operate depth and angle adjustment system is adopted. In terms of safety, intelligent sensing technology, automatic braking system and intelligent adjustment of protective cover are introduced. Power transmission adopts efficient motors and optimized transmission systems to reduce energy consumption and improve cutting efficiency. The innovation of working platform and bracket develops multifunctional and adjustable design to adapt to a wide range of working scenarios and different workpiece requirements, improve stability and flexibility, and also includes lighting mechanism.

[0032] Specifically, by pulling the third fixed column 16, the first rack 9 is driven to move while the third fixed column 16 is moved, which causes the gear 10 meshing therewith to rotate.

[0034] Specifically, by pulling the wrench 22, the force of the wrench 22 causes the rotating column 23 to rotate. The movement of the rotating column 23 drives the rotating plate 24 at the bottom to rotate, and then the rotating plate 24 acts on the bent plate 26 at the top. The moving force of the bent plate 26 causes the connecting frame 27 of the side wall to start moving, and at the same time, the movement of the connecting frame 27 causes the spring 25 fixed to the inner wall to contract. The movement of the connecting frame 27 also causes the slider 21 of the side wall to resist, and the slider 21 slides inside the hollow plate 32. Then, the handle 3 can be pulled, and the movement of the handle 3 causes the slider 21 to move. The movement of the slider 21 drives the clamping block 20, and the bottom of the clamping block 20 slides on the top of the turntable 6, thereby successfully clamping the plate.

[0035] Reference Figure 1 The top of the workbench 31 is fixedly connected to a base 7, the top of the base 7 is rotatably connected to a turntable 6, the side wall of the turntable 6 is fixedly connected to a connecting shaft 5, the inside of the connecting shaft 5 is slidably connected to a fourth fixed column 29, one end of the fourth fixed column 29 is fixedly connected to a cutting machine 4, one side of the cutting machine 4 is fixedly connected to a handle 30, and the bottom of the cutting machine 4 is slidably connected to a protective cover 28.

[0036] Specifically, when using the multifunctional electric saw, the cutting machine 4 is first rotated to perform cutting operations. Subsequently, the cutting machine 4 can be driven to move by setting the fourth fixed column 29. The outer wall of the fourth fixed column 29 is slidably connected to the inside of the connecting shaft 5, and one side of the connecting shaft 5 is fixed to the outer wall of the turntable 6. The turntable 6 can effectively control the flying chips through the protective cover 28 to prevent them from flying around by rotating on the top of the base 7. At the same time, pulling the handle 30 can drive the cutting machine 4 to move, thereby achieving a precise cutting effect on the material.

[0037] Working principle: When using the multifunctional electric saw, firstly, the cutting machine 4 is rotated to perform the cutting operation, and then the cutting machine 4 can be driven to move by setting the fourth fixed column 29, and at the same time, the outer wall of the fourth fixed column 29 slides inside the connecting shaft 5, and one side of the connecting shaft 5 is fixed to the outer wall of the turntable 6, and at the same time, the turntable 6 is rotated on the top of the base 7, and thus the flying chips can be controlled by the protective cover 28 to prevent the flying chips from flying everywhere, and the handle 30 is pulled to drive the cutting machine 4 to move, so as to achieve the effect of cutting the material, and then the third fixed column 16 is pulled, and at the same time, the movement of the third fixed column 16 drives the first rack 9 to move, and the movement of the first rack 9 can drive the gear 10 meshing therewith to rotate, and the gear 10 is also moved on the surface of the second rack 13, and then one side of the second rack 13 is fixed inside the first hollow column 8, and at the same time, the gear 10 rotates at the bottom of the second hollow column 12, and at the same time, the first rack 9 is fixed to the bottom of the third fixed column 16, and one side of the first connecting plate 11 The first connecting plate 11 is fixed to the bottom of the second hollow column 12, and the gear 10 is rotated inside the first connecting plate 11, so as to achieve the effect of adjusting the height of the lighting lamp 19. In addition, the cooperation between the first L-shaped connecting plate 17 and the second L-shaped connecting plate 18 can make the lighting lamp 19 have various angle adjustment functions. Next, by pulling the wrench 22, the force of the wrench 22 drives the rotating column 23 to rotate, and the force of the rotating column 23 drives the rotating plate 24 at the bottom to rotate, and the rotating plate 24 drives the bent plate 26 at the top to rotate, and at the same time At the same time, the force applied to the bending plate 26 can drive the connecting frame 27 of the side wall to move, and the movement of the connecting frame 27 can drive the spring 25 fixed to the inner wall to contract. At the same time, the movement of the connecting frame 27 will press the slider 21 of the side wall, and the slider 21 will slide inside the hollow plate 32. Then, the handle 3 can be pulled, and the force applied to the handle 3 will drive the slider 21 to move. At the same time, the movement of the slider 21 can drive the clamping block 20 to move, and the bottom of the clamping block 20 slides on the top of the turntable 6, thereby achieving the effect of clamping the plate.
