An auxiliary handle for an electric tool comprising a housing having a first engaging portion, a second engaging portion, and a third engaging portion, the auxiliary handle comprising:
- a handling portion;
- a fixing portion;
- and
- a locking portion,
- wherein the handling portion enables a user to handle the auxiliary handle and operate the locking portion,
- wherein the fixing portion is adapted to engage with the first engaging portion and the second engaging portion so as to removably connect the auxiliary handle to the housing,
- the locking portion is adapted to interact with the third engaging portion so as to lock the auxiliary handle, the locking portion comprises an actuating member fixedly connected to the handling portion and a locking member at least partially accommodated in the fixing portion, and
- the handling portion is operated so that the actuating member acts on the locking member whereupon a pressure is generated between the locking member and the third engaging portion of the housing to lock the fixing portion and the housing, and
- the actuating member is rod-shaped and the locking member is a steel ball, and the fixing portion is generally U-shaped and has a main extending axis and two clamping members extending generally perpendicular to the main extending axis, the clamping members being engaged with the first engaging portion and the second engaging portion of the housing respectively, the fixing portion having a hole along the main extending axis and a groove facing the housing and communicated with the hole, the locking member being accommodated in the groove and partially protruding from the groove, and the actuating member having one end fixedly connected to the handling portion and the other end accommodated in the hole.
An electric tool, comprising:
- a housing;
- a motor arranged in the housing;
- a transmission mechanism driven by the motor;
- a working head driven by the transmission mechanism;
- a main handle extending from the housing;
- and
- an auxiliary handle removably fixed on the housing, the auxiliary handle comprising:
- a handling portion, a fixing portion and a locking portion, the handling portion enabling the user to handle the auxiliary handle and operate the locking portion,
- wherein the housing has a first engaging portion, a second engaging portion, and a third engaging portion arranged between the first engaging portion and the second engaging portion, the fixing portion being engaged with the first engaging portion and the second engaging portion so as to connect the auxiliary handle to the housing, and the locking portion interacting with the third engaging portion so as to lock the auxiliary handle,
- the locking portion comprises an actuating member fixedly connected to the handling portion and a locking member at least partially accommodated in the fixing portion, and the handling portion is operated to enable the actuating member to act on the locking member so that a pressure is generated between the locking member and the third engaging portion of the housing to lock the fixing portion and the housing, and
- wherein the actuating member is rod-shaped and the locking member is a steel ball, and the fixing portion is generally U-shaped and has a main extending axis and two clamping members extending generally perpendicular to the main extending axis, the clamping members being engaged with the first engaging portion and the second engaging portion of the housing respectively, the fixing portion having a hole along the main extending axis and a groove facing the housing and communicated with the hole, the locking member being accommodated in the groove and partially protruding from the groove, and the actuating member having one end fixedly connected to the handling portion and the other end accommodated in the hole.
