Driving apparatus
A handheld driving apparatus includes a container having a grasping member, a lock member having a protrusion, a trigger lever, and an action unit. The lock member moves between first and second positions along right and left directions. The second position is a fully pressed position. The trigger lever moves between third and fourth positions. The fourth position is a fully pressed position. The trigger lever is restricted from moving toward the fourth position by contacting the first protrusion when the lock member is in the first position. The trigger lever is free to move toward the fourth position without contacting the first protrusion when the lock member is in the second position. The action unit performs a mechanical action for mowing or cutting an object when the trigger lever is in the fourth position.
1. A handheld driving apparatus for mowing or cutting an object, the handheld driving apparatus being extended along a longitudinal direction from a container to an action unit in a plan view, the handheld driving apparatus comprising:
the container having a grasping member, the grasping member being configured to be held by a user while operating the handheld driving apparatus;
a lock member
including a first protrusion and a second protrusion, and
configured to be movably connected to the grasping member and move between a first position and a second position along a right and left direction, the first position being a rest position of the lock member, the second position being a fully pressed position of the lock member, the right and left direction being perpendicular to the longitudinal direction in the plan view;
a trigger lever configured
to be movably connected to the grasping member and move between a third position and a fourth position, the third position being a rest position of the trigger lever, the fourth position being a fully pressed position of the trigger lever,
to be restricted to move toward the fourth position in a first moving direction by contacting with the first protrusion of the lock member when the lock member is at the first position, and
not to be restricted to move toward the fourth position in the first moving direction without contacting with the first protrusion of the lock member when the lock member is at the second position;
the action unit
provided on the front side of the container, and
configured to drive in such a manner that a mechanical action for mowing or cutting the object is applied to the object when the trigger lever is at the fourth position; and
a holding member configured
to be movably connected to the grasping member and move between a fifth position and a sixth position, the fifth position is a rest position of the holding member, and the sixth position is a fully pressed position of the holding member,
to be restricted to move toward the sixth position in a second moving direction by contacting with the second protrusion of the lock member when the lock member is at the first position,
not to be restricted to move toward the sixth position in the second moving direction without contacting with the second protrusion of the lock member when the lock member is at the second position, and
to restrict the movement of the lock member when the holding member is at the sixth position.
2. The handheld driving apparatus according to claim 1 , further comprising a first elastic member, wherein:
the first elastic member is provided between the lock member and the grasping member, and the first elastic member is configured to energize the lock member along the right and left direction from the second position to the first position, and
the lock member is configured to move from the first position to the second position by being pressed along the right and left direction.
3. The handheld driving apparatus according to claim 1 , wherein:
the holding member include another elastic member between the holding member and the grasping member, and the second elastic member is configured to energize the holding member in a direction from the sixth position to the fifth position.
4. The handheld driving apparatus according to claim 1 , further comprising:
a limit switch
arranged between the lock member and the trigger lever, and
configured to initiate to cause the action unit to be driven when the lock member moves to the second position and the trigger lever moves to the fourth position.
5. The handheld driving apparatus according to claim 1 , wherein
the grasping member extends along the longitudinal direction, and
a length along the longitudinal direction of the grasping member is larger than a width along the right and left direction of the grasping member.
