Detailed Description

Referring to fig. 1-4, a switch on angle grinder, includes casing 1, a fixed ship type switch 2 that sets up on casing 1, ship type switch 2 is including shift knob 3 that can automatic re-setting, is close to one side of shift knob 3 is provided with movable push rod 4, be equipped with gag lever post 5 on casing 1, the one end of movable push rod 4 is equipped with

spout

6, 6 covers of spout are established on gag lever post 5, make this one end of movable push rod 4 can rotate and slide on gag lever post 5, movable push rod 4 can to shift knob 3 and promote shift knob 3 opens ship type switch 2.

Wherein, be provided with first spring 7 between one end of spout 6 and gag lever post 5. The first spring 7 drives the movable push rod 4 to return.

The other end of the movable push rod 4 is connected with the casing 1 through a second spring 8, specifically, a positioning column 9 is arranged on the movable push rod 4, a positioning groove 10 is arranged at a position of the casing 1 opposite to the positioning column 9, and the second spring 8 is arranged between the positioning groove 10 and the positioning column 9. The movable push rod 4 is driven by the second spring 8 to be away from the switch button 3 when not receiving the pushing force, so that the boat-shaped switch 2 automatically resets and keeps the off state.

In order to make the angle grinder use more convenient, still set up locking shaft 11 on the casing 1, still be provided with locking trip 12 on the activity push rod 4, activity push rod 4 promotes shift knob 3 is opened during ship type switch 2, locking trip 12 can the hook cover be in on the locking shaft 11, make activity push rod 4 keeps constantly promoting shift knob 3 makes ship type switch 2 is in the state of opening. When the angle grinder needs to be used by two hands, the movable push rod 4 can be locked on the locking shaft 11, so that the boat-shaped switch 2 can be always turned on without continuously pushing the movable push rod 4, and the angle grinder can continuously work.

In order to enable the movable push rod 4 to control the state of the switch button 3 through a shorter stroke, the movable push rod 4 further comprises a pressure rod 13, and the pressure rod 13 pushes the switch button 3 to open the boat-shaped switch 2.

In order to facilitate the user to push the movable push rod 4 more easily, the movable push rod 4 is provided with a raised push block 14 on the part arranged outside the shell 1, according to the human engineering design.

The utility model discloses a working process: in the initial state, the movable push rod 4 is kept away from the boat switch 2 by the driving force of the first spring 7 and the second spring 8. When the angle grinder is used, the movable push rod 4 is pressed towards one side of the ship-shaped switch 2, the second spring 8 is stressed and deformed, then the movable push rod 4 is pushed towards the front of the angle grinder (the movable push rod can also be pushed towards the rear of the angle grinder according to different arrangement directions of the ship-shaped switch 2), the press rod 13 on the movable push rod 4 is used for shifting the switch button 3 on the ship-shaped switch 2 to be switched, the ship-shaped switch 2 is opened, and a circuit in the angle grinder is switched on, so that the angle grinder can be used. When an internal circuit needs to be disconnected, the first spring 7 and the second spring 8 start to act only by loosening the pressing of the movable push rod 4, the movable push rod 4 returns to the initial state, and the switch button 3 is not stressed any more at the moment and also automatically resets to close the ship-shaped switch 2.

The above is only an embodiment of the present invention, and is not a limitation to the present invention in any form, and the present invention does not depart from the technical solution of the present invention, and the simple modification, equivalent change or modification made by the present invention all fall into the protection scope of the present invention.
