Handheld cutting machines are also called stone cutting machines, electric circular saws, and marble machines. They can be used to cut materials such as stone, tiles, and wood. They can also be used for wall grooving during water and electricity installation. The corresponding saw blades are selected according to different cutting materials, and the large handle design makes it more comfortable to hold with both hands.

[0003] The cutting machine in the prior art includes: a circular saw blade; a shell having a fixed shield, the fixed shield including a receiving groove and a dust collecting pipe connected to the receiving groove, the circular saw blade is at least partially received in the receiving groove; a motor is received in the shell and has a motor shaft axis, the motor is used to drive the circular saw blade to rotate around the rotation axis. The handheld cutting machine is light and compact, easy to carry and operate, and workers can bring the handheld cutting machine to the work site anytime and anywhere without the need for additional equipment and fixed sites. At the same time, the handheld cutting machine is simple to operate, does not require auxiliary processes and skills, and improves work efficiency.

[0004] When using a handheld cutting machine for cutting, the rotation of the circular saw blade will lift up the chips and scatter them.

The movable rod 406 is provided with a movable hole, and the length of the movable hole is the same as the rotation path of the movable tooth 4091. The bottom of the kettle 3 is provided with threads around and is threadedly connected to the dust cover 2. The piston device inside the kettle 3 is evenly distributed with small holes to avoid one Too much water is discharged at one time, which affects the cutting object. A water outlet is provided at the bottom of the nozzle 301. Due to the rotation of the saw wheel 1, the water can be evenly distributed on the saw wheel 1 through centrifugal force, which effectively cools the saw wheel 1. Holes are provided on both sides of the dust discharge device 201. The saw wheel 1 is made of titanium alloy. This material has good corrosion resistance, heat resistance and wear resistance, and is suitable for high-speed and high-tension wire cutting. It can effectively reduce the inertia of the guide wheel and increase the life of the machine. There is a protective plate on the outside of the gear rotating device to prevent the gear from shifting during operation.

[0020] In a preferred embodiment, it includes a saw wheel 1 and a piston tube 4, wherein a motor 5 is fixedly connected to the bottom of the piston tube 4, a turntable 501 is fixedly connected to one side of the motor 5, a rotor 502 is fixedly connected to one side of the turntable 501, a rotating rod 503 is fixedly connected to one side of the rotor 502, a cross connecting plate 5031 is fixedly connected around the rotating rod 503, a fixed arm 8 is fixedly connected to one side of the motor 5, a handle 6 is fixedly connected to the middle of the fixed arm 8, and a switch handle 7 is fixedly connected to one side of the fixed arm 8.

[0022] In a preferred embodiment, it includes a motor 5, one side of which is fixedly connected to a motor connecting rod 909, one side of which is fixedly connected to an upper fixing seat 908, the bottom of which is fixedly connected to an upper supporting leg 906, one side of which is fixedly connected to a wrench 907, the bottom of which is fixedly connected to an upper supporting plate 905, the bottom of which is fixedly connected to four fixing rods 903, the bottom of which is fixedly connected to a supporting plate 902, the bottom of which is fixedly connected to a shell 904, the bottom of which is fixedly connected to a supporting leg 901, and the bottom of which is fixedly connected to a suction cup 9.

[0023] In this embodiment, it is necessary to specifically supplement that: threads are provided at the top and bottom of the four fixing rods 903, and are threadedly connected to the upper support plate 905 and the support plate 902. A spring is provided inside the outer shell 904. When the wrench 907 is pulled, the lifting and adsorption device automatically moves downward due to the action of gravity. When it moves downward to a certain height, the wrench 907 is pulled closer. When in use, the lifting and adsorption devices on both sides are at the same height to avoid deviation during cutting.

[0024] The working principle of the present invention is as follows: when using a cutting device for processing an office desk, first fix the suction cup 9 on the desktop, pull up the wrench 907 to adjust the height of the cutting device, and under the action of gravity, the lifting and fixing device will automatically move downward.

Press the switch handle 7 with one hand and hold the auxiliary handle 6 with the other hand. After the cutting device is started, the cross connecting plate 5031 will drive the rotating gear 409 to rotate, and the rotating gear 409 will drive the movable gear 4091 to rotate. Since the rotation of the movable gear 4091 will drive the entire piston device to move, the movement of the piston device will drive the motor 5 through the air inlet pipe 402. The hot air generated in the kettle 3 is sucked out, and then the piston device will suck out the hot air through the air outlet pipe 401, and the sucked out hot air is blown into the dust cover 2. The sucked out hot air can assist in discharging the debris generated during cutting from the dust discharge device 201, so as to avoid the motor emitting heat during long-term use of the handheld cutting machine, which may cause damage to the handheld cutting machine and affect work efficiency. When the piston device moves, it will also drive the piston in the kettle 3 to move. Through the up and down movement of the movable connecting rod 303, the water in the kettle 3 is squeezed and sprayed out from the nozzle 301. Due to the rotation of the saw wheel 1, the water can be evenly distributed on the saw wheel 1 through centrifugal force, which effectively cools the saw wheel 1. Since the amount of water discharged at one time is not much, it will not affect the cutting object.

[0025] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principle of the present invention should be included in the protection scope of the present invention.
