Reciprocating tool
11701722 · 2023-07-18 · ·

Providing a reciprocating tool capable of reducing vibrations generated during operations and improving work performance and processing precision. A reciprocating tool includes a transmission gear part 61 and a counter weight part 62. The transmission gear part 61 includes a bevel gear 611 and a weight 611A. The bevel gear 611 is rotatable in a first direction about an axis B by receiving a drive force of a motor 3. The weight 62A is rotatable in a second direction opposite to the first direction about the axis B by receiving the drive force of the motor 3. A center of gravity 61G of the transmission gear part 61 and a center of gravity 62G of the counter weight part 62 are separated farthest from a blade mounting part 8 when the blade mounting part 8 is positioned in a rearward position. The center of gravity 61G of the transmission gear part 61 and the center of gravity 62G of the counter weight part 62 are closest to the blade mounting part 8 when the blade mounting part 8 is positioned in a forward position.

RECIPROCATING TOOL
20170361386 · 2017-12-21 ·

A reciprocating tool employs a motor gear of a drive motor to rotate a drive shaft. When the drive shaft rotates, a sliding member disposed into a ball rolling groove will move along the path of the ball rolling groove. At the same time, for the restriction of annular fixing member, the component force of the sliding member in an axial direction pushes a driven shaft to move back and forth repeatedly along the axial direction, so that a tool fixed on the driven shaft will also back and forth repeatedly in the axial direction, and thus a high efficient reciprocating tool is achieved.

Clamping Apparatus with Control Mechanism for Spring-Actuated Lever
20170282329 · 2017-10-05 ·

A clamping apparatus with a control mechanism includes a cam, a cam post, a handle, and a handle plate. The cam is configured to rotate into a clamped position in which the clamping apparatus is in a clamped state and an unclamped position in which the clamping apparatus is in an unclamped state. The cam post is rotatable with the cam. The handle is movable into a first position and a second position. The handle plate is rotatable with the handle. The handle plate is configured to rotate the cam post in a first direction when the handle moves from the first position to the second position. The handle plate is configured to rotate in a second direction without rotating the cam post in the second direction for a predetermined distance when the handle moves from the second position to the first position. The first direction is opposite to the second direction.

Power tool

There is provided a power tool in which impact applied to a power transmission portion can be mitigated to thereby suppress components constituting the power transmission portion from being deformed and damaged. The power tool includes a brushless motor 3 having a rotation shaft portion 31 rotatable about a rotation axis A1, a housing 2 accommodating therein the brushless motor 3, a power transmission portion 6 configured to receive a rotation force of the rotation shaft portion 31 and to transmit a driving force based on the rotation force, and a driven portion 7 configured to be driven by receiving the transmitted driving force. The rotation shaft portion 31 is supported by the housing 2 so as to be movable relative to the housing 2 in an axial direction of the rotation axis A1.
