Publication number: 20170157747Abstract: The invention discloses a single-shaft hand tool, which comprises a first body and a second body. Wherein the first body is provided with a groove, the second body is provided with a protrusion, the protrusion is mounted within the groove in a nested manner, thus enabling the first body to be pivotally connected to the second body by means of a virtual pivot. The invention also discloses a double-shaft hand tool, which comprises a first body and a second body. The first body is pivotally connected to the second body by means of a virtual pivot. The first body is provided with a third groove and a first hole, the second body is provided with a fourth groove and a second hole. A first fastener passes through the first hole and the fourth groove. Meanwhile, a second fastener passes through the second hole and the third groove. Therefore, the first body is fixedly connected to the second body in the direction parallel to the axis of the virtual pivot.Type: ApplicationFiled: July 11, 2014Publication date: June 8, 2017Inventor: Min Wang

Publication number: 20170157748Abstract: The present invention provides a wrench, and its structure includes a guide rod, a first pawl mounted on the guide rod, a sliding member sheathed on the guide rod, a second pawl mounted on the sliding member and matching with the first pawl, and a toothed block disposed on the sliding member and matching with the guide rod. The toothed block has a first position and a second position. When the toothed block is in the first position, the toothed block is slidable along the guide rod toward the first pawl, and is locked in the direction away from the first pawl. When the toothed block is in the second position, the toothed block is slidable along the guide rod toward or away from the first pawl.Type: ApplicationFiled: July 11, 2014Publication date: June 8, 2017Inventor: Min WANG

Publication number: 20170157749Abstract: An apparatus to be used as an alternative for a wrench contains a fastener receiving head, a tubular body, a receiving channel, a first arm, and a second arm. The fastener receiving head is terminally connected to the tubular body and is designed to fit around a bolt head. The receiving channel traverses through the tubular body and the fastener receiving head so that a supply line associated with a faucet setup can be positioned within the receiving channel. The first arm and the second arm are perpendicularly connected to the tubular body so that the tubular body can be rotated by holding the first arm and the second arm.Type: ApplicationFiled: December 5, 2016Publication date: June 8, 2017Inventor: Aaron W Levy

Publication number: 20170157750Abstract: A skateboard tool having a fastener-engaging piece and a nut-engaging piece which work cooperatively to unscrew multiple fasteners simultaneously. The fastener-engaging piece has a handle and a body. The handle is rigidly connected to a shaft which extends into the body and is rotatably connected with a set of interconnected gears. The handle and shaft are rotatable with respect to the body. The body also includes a plurality of fastener-engaging bits that are rotatably driven by the gears. The handle and shaft are rotated, which in turn rotates the gears and rotates the fastener-engaging bits. There is also provided a wrench for engaging, and rotatably locking, nuts secured to the fasteners that are rotated by the fastener-engaging bits. The wrench has an elongated U-shaped body having a pair of legs and a connector base piece. Each of the legs includes at least one nut-receiving socket.Type: ApplicationFiled: December 7, 2016Publication date: June 8, 2017Inventor: David Koenes

Publication number: 20170157751Abstract: An impact spinning hand tool includes a hollow body, a first lever and a first elastic member. The hollow body includes a first position-limiting structure. The first lever includes a driving end exposed outside the hollow body, a spinning structure and a forcing end contained in the hollow body. The forcing end has a second position-limiting structure that is detachably limited by the first position-limiting structure. The first elastic member is pushed against the forcing end and the first position-limiting structure through two ends thereof. The first lever is located at a first position and presses the first elastic member to store an elastic restoring force when being connected with the hollow body. When the second position-limiting structure is released, the elastic restoring force drives the first lever to move to a second position so as to allow the spinning structure to perform an impact spinning action.Type: ApplicationFiled: December 4, 2016Publication date: June 8, 2017Inventor: Chih-Ching HSIEH

Publication number: 20170157752Abstract: An operation switch sends an ON signal to a control processor indicating the operation switch is triggered by a user. A magnetic sensor sends a sensor signal to the control processor based on a displacement of a chip rod in a rearward direction. In the case where the sensor signal has not yet been sent, the control processor performs a control in a first mode where a brushless DC motor is not driven. In the case where sensor signal is sent, control processor performs a control in a second mode wherein the brushless DC motor is driven. An output in the first mode is lower than in the second mode. Because of this manner of construction, even if an ON input is triggered and held by the user, electric power is conserved while the operation switch is switched on and a hexagonal nut is not fastened, improving power consumption efficiency.Type: ApplicationFiled: April 8, 2015Publication date: June 8, 2017Applicant: MAKITA CORPORATIONInventors: Takeshi NISHIMIYA, Kazunori TSUGE, Nobuyasu FURUI

Publication number: 20170157753Abstract: An electric power tool includes a housing, a motor, a deceleration mechanism, a final output shaft, a vibration mechanism, a vibration switching member, a stop member, and an expansion prevention portion. The vibration mechanism provides a vibration in an axial direction to the final output shaft. The vibration switching member is accommodated in a slit axially disposed on a front end of a tubular portion and moved back and forth in the slit by an operation from outside to switch on and off actuation of the vibration mechanism. The stop member is installed on the front end of the tubular portion to cover the slit.Type: ApplicationFiled: November 9, 2016Publication date: June 8, 2017Applicant: MAKITA CORPORATIONInventor: Hidenori NAGASAKA
