Abstract: A work tool switches smoothly between operational modes and has a lever member that is easily joined. The work tool includes an operation member, a lever member, and a switching member. The lever member is swingable about a support shaft in response to an operation on the operation member and is swingable with the support shaft placed through the lever member. The lever member has an elongated hole through which the support shaft is placed. The elongated hole extends along the lever member. The switching member is linked with a swing of the lever member to move linearly.

Abstract: A cutting tool includes a rotary blade driven by a motor, a fixed blade disposed opposing the rotary blade, a housing holding the motor, and a battery mount part on a rear portion of the housing. The battery mount part has a guide groove that slidably receives a rail of a power tool battery pack. A blade cover is disposed partially around the rotary blade, and a portion or all of the blade cover has a shape in which the farther forward it goes the more it goes toward the side that has the fixed blade, viewed from the rotary blade. A base holds the fixed blade, and a portion or all of the base has a shape in which the farther forward it goes the more it goes toward the side that has the fixed blade, viewed from the rotary blade.

Abstract: An autofeed attachment (4) for a screw-driving apparatus (2) includes a base casing (30), a feeder casing (32) slidably mounted on the base casing (30) and a wheel (72) rotatably mounted within the feeder casing (32). When rotated in a forward direction, the wheel (72) advances a screw strip (50), which has a plurality of screws (52) coupled by a connecting strip. A wheel forward-direction rotating mechanism (60, 64, 66, 68) rotates the wheel (72) in the forward direction and restricts rotation of the wheel (72) in a reverse direction opposite the forward direction. A wheel-release mechanism (70, 107, 117) releases the restriction placed on rotation of the wheel (72) in the reverse direction. The wheel forward-direction rotating mechanism and the wheel-release mechanism are disposed, at least partially, inside of the wheel (72) and/or the rotational axis of the wheel (72) intersects a release button (107) of the wheel-release mechanism.

Abstract: An auxiliary handle (10) comprises a first clamp member (21), a second clamp member (31), an operation rod (40) and a grip (50). By rotation of the operation rod (40), the first clamp member (21) is moved toward a distal end of the operation rod (40), and at the same time, the second clamp member (31) is moved toward a base end of the operation rod (40). Accordingly, the first clamp member (21) and the second clamp member (31) are moved to be close to each other. As a result, an auxiliary handle attachable part (140) of a screw driver (100) is clamped by the first clamp member (21) and the second clamp member (31), and thereby the auxiliary handle (10) is attached to the screw driver (100).

Abstract: To reduce size increase, an impact tool includes a motor, a spindle located frontward from the motor and rotatable by the motor, a hammer supported by the spindle, an anvil strikable by the hammer in a rotation direction and having an insertion hole extending rearward from a front end of the anvil, a locking member supported by the anvil and movable to a locking position for locking a tip tool placed in the insertion hole and to an unlocking position for unlocking the tip tool, and a bit sleeve surrounding the anvil. The bit sleeve is movable to a movement-restricting position for restricting radially outward movement of the locking member and to a movement-permitting position for permitting radially outward movement of the locking member. The bit sleeve is at least partly between the hammer and the anvil in a radial direction.

Abstract: A power tool receives a reaction force with an auxiliary handle attached to the power tool. An auxiliary handle attachable to a power tool includes a first arm, a second arm that fastens, together with the first arm, at least a part of the power tool located between the first arm and the second arm, a handle, a grip sensor that detects the handle being gripped with the first arm and the second arm fastening at least the part of the power tool in between, and a signal output unit that outputs, to the power tool, a grip signal indicating that the handle is gripped based on a detection signal from the grip sensor.

Abstract: The drill includes a motor, a spindle rotatable with a rotational force transmitted from the motor, a clutch assembly that disables transmission of the rotational force to the spindle in response to a rotational load on the spindle reaching a release value and including an elastic member that adjusts the release value, and a change ring switchable from a clutch mode in which the clutch assembly is operable to a nonclutch mode in which the clutch assembly is inoperable in response to the change ring operated in a forward rotation direction. In the clutch mode, the elastic member elastically deforms to reduce the release value in response to the change ring operated in the forward rotation direction, and to increase the release value in response to the change ring operated in a backward rotation direction.

Abstract: A power tool allows mode switching and clutch operation torque switching using a single ring. An electric vibration driver drill includes an internal gear that meshes with planetary gears, an internal gear lock pin that moves forward relative to the internal gear to lock the internal gear, a first vibration cam fixed to a spindle, a second vibration cam that rubs against the first vibration cam and rotate relative to a gear housing, a vibration switch lever that moves forward relative to the second vibration cam to lock the second vibration cam in a nonrotatable manner, and an annular change ring that switches between forward movement and rearward movement of the internal gear lock pins and switches between forward movement and rearward movement of the vibration switch lever.
