Description

Technical Field

[0001] The utility model relates to the technical field of electric tools, in particular to an angle grinder capable of preventing accidental touch. Background Art

[0002] Nowadays, people often use grinding tools in their daily production and life, and angle grinder is a common grinding power tool. Angle grinder, also known as grinder or disc grinder, is a portable power tool that uses fiberglass for cutting and grinding. It is mainly used for cutting, grinding and brushing metal and stone.

[0003] When using the common angle grinders on the market, one only needs to press the switch button to make the motor rotate, driving the sanding disc or cutting disc to rotate and then grind and cut the raw material, which is very convenient to use; however, when the user holds the angle grinder to work, due to the compact overall structure of the angle grinder, it is very easy to touch the switch button during use, causing the switch button to be accidentally touched, causing the angle grinder in the user's hand to be accidentally turned on or off, which not only affects the normal use of the angle grinder, but also poses a greater hidden danger to the user's work safety. Utility Model Content

[0004] In order to solve the above problems, the utility model proposes an angle grinder that prevents accidental touches, which solves the problem that the traditional angle grinder switch is easily accidentally touched.

[0005] The technical solution adopted by the utility model is: an angle grinder for preventing accidental touch, comprising a shell, a motor and a battery pack are installed in the shell, the motor is powered by the battery pack, an output shaft is arranged on the motor, the output shaft is used to install a sanding sheet or a cutting sheet, a protective cover is arranged on the outer side of the output shaft, a switch assembly is arranged on the shell, the switch assembly comprises a sliding switch and a boat-type switch, the shell is provided with a mounting groove corresponding to the sliding switch, the sliding switch and the mounting groove are slidably connected, the boat-type switch is located in the shell, the sliding switch is provided with a toggle piece corresponding to the boat-type switch, a mounting post is arranged on the sliding switch, the mounting post is located between the sliding switch and the toggle piece, and a strip-shaped limiting hole for the mounting post to pass through is opened at the bottom of the mounting groove.

[0006] Through the above technical solution, the sliding switch is pushed upward in the installation groove, and the toggle piece moves upward with the sliding switch. After moving a certain stroke, the toggle piece and the boat-shaped switch abut each other, and the sliding switch is continuously pushed upward, so that the boat-shaped switch triggers the battery pack under the action of the toggle piece, the battery pack starts to supply power, the motor starts working, and the user can use the angle grinder for cutting and grinding operations; when the grinder needs to be turned off, the user only needs to push the sliding switch downward, and after moving a certain stroke, the toggle piece and the boat-shaped switch abut each other, and the sliding switch is continuously pushed downward so that the battery pack turns off the power supply, and the grinder stops running; when the user turns the grinder on or off, the user needs to push the sliding switch a certain stroke before the boat-shaped switch is triggered, so that the grinder will not be turned on or off immediately when the user accidentally touches the sliding switch, leaving the user a certain reaction time to correct the wrong operation in time, so that the safety of the user when using the grinder is greatly improved.

[0007] Furthermore, the rocker switch includes a swing block and a fixed block, the swing block is mounted on the fixed block, the toggle member includes a connecting piece and a positioning protrusion, the connecting piece and the positioning protrusion are fixedly connected, and the swing block is driven by the positioning protrusion.

[0008] Through the above technical solution, the user pushes the sliding switch to make the connecting plate and the positioning protrusion move synchronously. After the positioning protrusion contacts the swing block, the swing block is driven to swing on the fixed block, thereby controlling the opening and closing of the battery pack, making the grinder very sensitive to opening and closing.

[0009] Furthermore, a limiting protrusion is arranged on the side of the strip-shaped limiting hole, a positioning groove is arranged at the bottom of the sliding switch corresponding to the limiting protrusion, and the limiting protrusion and the positioning groove are slidably connected.

[0010] Through the above technical solution, the coordinated use of the limiting protrusion and the positioning groove makes the sliding switch very stable as a whole during the sliding process in the installation groove, avoiding the sliding switch from being offset due to excessive pushing force of the user, and limiting the position of the sliding switch.

[0011] Furthermore, a mounting seat is provided in the housing, and the rocker switch is embedded in the mounting seat.

[0012] Through the above technical solution, the rocker switch is embedded in the mounting seat so that the rocker switch is installed very firmly in the housing. When the user uses the grinder to operate, the rocker switch will not be affected, thereby ensuring the overall sensitivity of the switch assembly.

[0013] Furthermore, a limiting groove is provided in the shell, and the connecting piece is slidably connected in the limiting groove.

[0014] Through the above technical solution, the connecting piece is installed in the limiting groove so that when the connecting piece slides back and forth with the sliding switch, the connecting piece can slide stably in the limiting groove to avoid affecting the abutment between the positioning protrusion and the swing block due to the deviation of the connecting piece.

[0015] Furthermore, a spline is installed on the output shaft, a limit seat is arranged in the shell corresponding to the spline, a locking button is passed through the limit seat, a limit groove is arranged on the spline corresponding to the locking button, and a mounting hole for the locking button to pass through is arranged on the shell.

[0016] Through the above technical solution, the cooperation between the spline and the locking button allows the user to easily replace the sanding disc or cutting disc of the angle grinder. BRIEF DESCRIPTION OF THE DRAWINGS
