Technical Field

[0001] The utility model relates to the technical field of electric tools, in particular to a portable electric circular saw with safety protection. Background Art

[0002] A circular saw is a power tool designed for cutting wood. Its main components include a motor, saw blade, guard, base, handle, and power cord. The motor provides power, driving the saw blade for cutting; the guard protects the operator from the high-speed blade, preventing injury. The base and handle provide a stable operating platform and a comfortable grip, while the power cord provides energy. Circular saws are widely used, including in construction, renovation, furniture manufacturing, and DIY projects.

[0003] While existing circular saw designs incorporate cord storage, the lack of an effective winding mechanism means the cord remains tangled and untidy. This not only increases the saw's overall size, making it inconvenient to carry and store, but can also damage the cord and even lead to safety hazards such as electric shock. Currently, no effective solution has been proposed to address these issues. Utility Model Content

[0026] like Figure 1-Figure 4As shown, according to the embodiment of the utility model, the portable safety protection electric circular saw includes a bottom plate 1, a fixed cover 2 is fixedly connected to the top of the bottom plate 1, a saw blade 3 is arranged inside the fixed cover 2, the saw blade 3 is connected to the drive motor 4 through a transmission shaft, a handle 5 is provided on one side of the drive motor 4, a switch 6 is provided on the handle 5, one end of the handle 5 is connected to a power cord 7, the power cord 7 is connected to a plug 8, a fixed plate 9 is provided on one side of the bottom plate 1, a winding mechanism 10 is provided above the fixed plate 9, and the winding mechanism 10 includes a The winding pile 1001 has a buckle 1002 on one side of the top of the winding pile 1001, a socket 1003 on the top of the winding pile 1001, a mounting groove 1004 on the bottom of the winding pile 1001, a mounting block 1005 on the fixing plate 9, the mounting block 1005 matches the mounting groove 1004, and a limiting mechanism 11 is provided inside the mounting block 1005 and the fixing plate 9. The limiting mechanism 11 includes a card slot 1101 inside the mounting block 1005, a card block 1102 inside the card slot 1101, and a card block 1103. There are two 102, and a connecting block 1103 is connected to the bottom end of the card block 1102. A groove 1104 is provided inside the fixed plate 9, and the width of the groove 1104 matches the connecting block 1103. The two connecting blocks 1103 are connected by a spring 1105. A movable block 12 is connected to one side of the connecting block 1103. An opening 13 is provided inside the fixed plate 9, and the height of the movable block 12 matches the opening 13. An infrared sensor 14 is provided at one end of the outer side of the bottom plate 1. The infrared temperature sensor uses the thermal effect principle of infrared rays to sense temperature changes in the surrounding environment. The infrared sensor 14 is electrically connected to the controller 15, and the controller 15 is electrically connected to the drive motor 4. The controller 15 is arranged inside the handle, and a grip 16 is provided on one side of the handle 5. The grip 16 is connected to the fixed cover 2. A movable cover 17 is provided below the fixed cover 2, and the movable cover 17 is movably connected to the fixed cover 2. By setting the movable cover 17, when the saw blade 3 is not in use, the saw blade 3 can be protected by the movable cover 17 to ensure the protection effect of the saw blade 3.

[0027] In order to facilitate understanding of the above technical solutions of the present invention, the working principle or operation method of the present invention in actual process is described in detail below.

[0028] In actual application, when the electric circular saw needs to be used, the movable plate can be moved to drive the block 1102 to move, so that the limiting effect of the block 1102 on the winding pile 1001 becomes invalid, so that the winding pile 1001 can be disassembled, which is convenient for the user to spread out the power cord 7 and ensure the normal use of the handle 5. When the power cord 7 is connected through the plug 8, the electric circular saw can be used normally. By setting the infrared sensor 14, the electric circular saw can detect potential dangers in time and take corresponding measures when the user's fingers or other parts are close to the saw blade 3. When the user's body temperature is close to the saw blade 3 area, the sensor will immediately capture this temperature change and The information is transmitted to the controller 15, and the controller 15 will control the drive motor 4 to stop rotating to ensure the safety of the circular saw operation. After the circular saw is used, the power cord 7 can be wound around the winding pile 1001, which effectively reduces the disorder of the power cord 7. By moving the movable plate again, the card block 1102 can be driven to retract into the card slot 1101, so that the installation slot 1004 of the winding pile 1001 can be placed inside the installation block 1005. Then, by loosening the movable block 12, under the action of the spring 1105, the card block 1102 will be placed on the outside of the top of the installation slot 1004, which can fix the bottom end of the winding pile 1001 and ensure the fixing effect of the power cord 7.

[0029] To sum up, with the help of the above-mentioned technical solution of the present invention, by setting up the winding mechanism 10, when the electric circular saw is not in use, the power cord 7 can be neatly wound around the winding pile 1001, thereby effectively reducing the disorder of the power cord 7 and improving the portability and storage convenience of the electric circular saw. After the power cord 7 is wound around the winding post 1001, the power cord 7 and plug 8 can be fixed by the buckle 1002 and the socket 1003, preventing the power cord 7 from moving during transportation and storage, thereby reducing the risk of damage to the power cord 7 and avoiding safety accidents such as electric shock caused by the loose power cord 7. In addition, by providing the fixing plate 9 and the limiting mechanism 11, the winding post 1001 can be firmly fixed and easily removed, making it more convenient to unwind and wind the power cord 7, thereby increasing the convenience of use. In addition, by providing the infrared sensor 14, the electric circular saw can promptly detect potential dangers when the user's fingers or other parts approach the saw blade 3 and take corresponding measures. When the user's body temperature approaches the area of ​​the saw blade 3, the sensor will immediately capture this temperature change and transmit the information to the controller 15. Once the controller 15 receives the information of the person approaching from the infrared temperature sensor, it will quickly react and control the drive motor 4 to stop moving, preventing the drive motor 4 from continuing to rotate and causing harm to the user, thereby enhancing the safety of the electric circular saw.

[0030] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention.
