摘要： A spike puller for pulling a railroad spike of a track includes a housing, a linear displacement unit mounted at the housing, and a claw unit for gripping the railroad spike. The claw unit is displaceable in a linear manner relative to the housing in a displacement direction by using the linear displacement unit. The linear displacement unit includes a hollow tube which is guided in the housing. An electric drive unit electrically operates the linear displacement unit. A method for pulling a railroad spike of a track is also provided.

摘要： A gas-spring type driving tool with a charge valve, a relief valve, and an opening valve provided in an accumulation chamber. Compressed gas can be quickly charged into the accumulation chamber by connecting the charge valve to an external device. The relief valve maintains the accumulation chamber at a preset pressure. The opening valve is capable of opening the accumulation chamber quickly to the atmosphere. This allows for a quick removal of a jammed nail from a driving nose.

摘要： A fastener driving tool and an adapter for a fastener driving tool are described herein for permitting accurate placement of fasteners with respect to an edge of a board (e.g., a top edge of a siding board). The adapter may include an adapter body having a central opening for receiving a head of a fastener driving tool and two or more pins positioned in the adapter body. At least two of the pins are positioned in the adapter body such that, when the central opening receives the head, the pins are equidistant from a center of a barrel through which the fastener driving tool drives fasteners.

摘要： A gas spring-powered fastener driver includes a cylinder, a moveable piston positioned within the cylinder, a driver blade attached to the piston and movable between a ready position and a driven position, a lifter engageable with the driver blade to return the driver blade from the driven position to the ready position, and a multi-stage planetary transmission including an output shaft operatively coupled to the lifter to provide torque thereto, a first bearing supporting a first portion of the output shaft for rotation, a second bearing supporting a second portion of the output shaft for rotation, and first and second planetary stages. The fastener driver also includes a housing having a cylinder support portion and a transmission housing portion in which the first and second bearings are received. The cylinder support portion and the transmission housing portion are integrally formed as a single piece.

摘要： Realized is a driving device capable of controlling driving timing of a blade and driving timing of a feeder independently. The driving device of the present invention has a housing having an injection path, a blade hitting a nail supplied to the injection path, an electric motor, a controller controlling drive of the electric motor, a magazine accommodating connected nails, and a supply, mechanism sequentially supplying the connected nails, which are accommodated in the magazine, to the injection path. The supply mechanism has a reciprocable feeder backward and forward, an energizing member energizing the feeder forward, and a stopper holding a position of the backward moved feeder against energization of the energizing member. Then, holding the position of the feeder by the stopper is released based on control of the controller.

摘要： A dustproof magazine to be mounted in a nail gun including a muzzle unit includes a magazine body, a nail-pressing member, and a scroll spring connected therebetween. The magazine body includes spaced-apart first and second rail walls extending transverse to the muzzle unit, and disposed respectively distal from and adjacent to the muzzle unit. The nail-pressing member is mounted movably along and between the first and second rail walls, and includes a main body and a scraper set extending therefrom. Movement of the nail-pressing member away from the muzzle unit drives the scroll spring to resiliently convert from a winding state into an unwinding state, where a strip portion of the scroll spring unwinds and extends along the second rail wall. The scraper set is in contact with the strip portion during the movement of the nail-pressing member for scrapping foreign matters off the strip portion.

摘要： A driving mechanism and a nail gun having the same. The driving mechanism includes a driving force supply unit comprising a frame structure having a front limiting seat and a rear limiting seat; a piston movably arranged between the front limiting seat and the rear limiting seat in the frame structure; a striker co-movably connected to the piston; and a spring assembly disposed between the piston and the rear limiting seat in the frame structure, configured such that when the piston is driven to move backward in the frame structure, the spring assembly is pushed into a contract state to store energy therein, and when the piston is free, the spring assembly expands to release the stored energy therein to push the piston to move forward in the frame structure so that the striker is co-moved therewith to strike a nail out of a muzzle.

摘要： A driving tool includes a driver moving along a driving passage and a lift mechanism for moving the driver. The driving tool includes a pusher and an idling strike prevention mechanism interlocking with a position of the pusher. The pusher pushes a driving member from a side opposite to a first end surface of a tool main body such that the driving member contacts a tip end of the driver at a standby position. When the driver moves from the standby position to a top dead center, the pusher supplies the driving member to the driving passage. After that, the driver moves downward to a driving position to drive the driving member. When no driving member is left, the idling strike prevention mechanism restricts activation of the driving tool in interlocking with the pusher such that the pusher moves to an activation restriction on a side of the driving passage.
