Switch assembly, control method of switch assembly and power tool

A method of activating a switch assembly, wherein

• the switch assembly including:
• a housing;
• a main control switch accommodated in the housing;
• a trigger switch arranged on the housing, wherein a first end of the trigger switch is exposed outside the housing, and a second end of the trigger switch is accommodated in the housing and is in contact with the main control switch;
• a first elastic piece and a second elastic piece, arranged in the housing;
• and
• a locking switch arranged on the housing, wherein
• a first end of the locking switch is exposed outside the housing, and a second end of the locking switch is in contact with the trigger switch,
• the locking switch is provided with a locking position and a releasing position,
• when the locking switch is in the locking position, the locking switch is opposite to the trigger switch and limits the action of the trigger switch, the trigger switch is in a locked state, and the main control switch cannot be started, and
• when the locking switch is located at the releasing position, the locking switch is located beside the trigger switch and limits are removed, the trigger switch is in a release state, and the main control switch can be started,
• the locking switch comprises a rotating portion and an abutting portion, the rotating portion is configured to be offset relative to the housing in the left and right direction of the rotating portion and rotated relative to the housing so that the abutting portion is synchronously driven to rotate for the trigger switch to be unlocked,
• the first elastic piece and the second elastic piece are respectively arranged on left and right sides of the rotating portion, the first elastic piece is used for driving the locking switch to reset when the locking switch is offset relative to the housing and the second elastic piece is used for driving the locking switch to reset when the locking switch is rotated;
• and
• the method comprising:
• toggling the locking switch towards one side, so that the locking switch being deviated relative to the housing, the locking switch moving from an opposite position of the trigger switch to a side position of the trigger switch, a limit between the locking switch and the trigger switch being released, and the locking switch being located at a releasing position;
• operating the locking switch to enable the locking switch to rotate relative to the housing;
• and
• operating a first end of the trigger switch to enable the trigger switch to rotate relative to the housing until the second end of the trigger switch triggering the main control switch, and the main control switch being started.

A power tool, comprising

• a motor;
• and
• a switch assembly to control activation or deactivation of the motor, wherein the switch assembly comprises:
• a housing;
• a main control switch accommodated in the housing;
• a trigger switch arranged on the housing, wherein a first end of the trigger switch is exposed outside the housing, and a second end of the trigger switch is accommodated in the housing and is in contact with the main control switch;
• a first elastic piece and a second elastic piece, arranged in the housing;
• and
• a locking switch arranged on the housing, wherein
• a first end of the locking switch is exposed outside the housing, and a second end of the locking switch is in contact with the trigger switch,
• the locking switch is provided with a locking position and a releasing position,
• when the locking switch is in the locking position, the locking switch is opposite to the trigger switch and limits the action of the trigger switch, the trigger switch is in a locked state, and the main control switch cannot be started, and
• when the locking switch is located at the releasing position, the locking switch is located beside the trigger switch and limits are removed, the trigger switch is in a release state, and the main control switch can be started,
• the locking switch comprises a rotating portion and an abutting portion, the rotating portion is configured to be offset relative to the housing in the left and right direction of the rotating portion and rotated relative to the housing so that the abutting portion is synchronously driven to rotate for the trigger switch to be unlocked,
• the first elastic piece and the second elastic piece are respectively arranged on left and right sides of the rotating portion, the first elastic piece is used for driving the locking switch to reset when the locking switch is offset relative to the housing and the second elastic piece is used for driving the locking switch to reset when the locking switch is rotated.
