A hand tool includes a trigger manually operated by an operator, a tool body configured to movably support the trigger, a biasing member configured to generate a biasing force for biasing the trigger in a direction opposite to a operation direction of the trigger, and a contacting member operated by a biasing force of the biasing member to act on the trigger or tool body. The biasing member and the contacting member are assembled integrally with the tool body or the trigger.

A hidden fastener and associated method for attaching decking members with side grooves to a support member includes a cross member and an elongate anchoring member. The cross member has a body with a front and rear end and defines a hole. The front end has at least one prong and the rear end includes a bent wing. At least one leg extends downward from the body intermediate the front and rear ends. Each of the front and rear ends are configured to engage with the groove of adjacent decking members. The front end is inserted into the groove of a leading decking member and the anchoring member is driven through the hole into the support member. A trailing decking member is placed with the rear end in the groove adjacent the leading decking member.

A fastener driver includes a housing defining a head portion and a handle portion, a drive mechanism positioned within the housing, and a firing mechanism. The firing mechanism includes a primary guide member supported within the head portion of the housing, a secondary guide member spaced from the primary guide member and supported within the head portion of the housing, a piston slidable along the primary guide member and the secondary guide member, a driver blade attached to the piston and configured to be movable along a drive axis, and a biasing member configured to move the piston and the driver blade from a top dead center (TDC) position toward a bottom dead center (BDC) position. A lifter assembly is operated by the drive mechanism to return the piston and the driver blade towards the TDC position, against the bias of the biasing member.

A return device includes a return wheel unit adapted to be mounted to a gun body of a fastening tool, and including a return wheel that is movable between a free position, where the return wheel is not in contact with an impact member of the fastening tool, and a return position, where the impact member is at a strike position and is not contact with a rotatable flywheel of the fastening tool, and where the return wheel is in contact with the flywheel and the impact member such that, when the flywheel rotates in a first rotational direction, the return wheel is driven by the flywheel to rotate in a second rotational direction opposite to the first rotational direction, and moves the impact member from the strike position to a standby position.

A quick release device for a panel of nail guns has a quick release mount, a pulling base, and an elastic element. The quick release mount is disposed on a body of a nail gun adjacent to a rear end of an ejecting track, and has two connecting boards and a pivotal rod connected to the two connecting boards. The pulling base is pressably connected to the quick release mount, selectively engages with a panel of the nail gun, and has an engaging hook, a pivot hole, and a pulling arm. The engaging hook is formed on the pulling base, and selectively engages with a limiting claw of the panel to limit a position of the panel relative to the ejecting track. The elastic element is mounted between the quick release mount and the pulling base to provide a returning force to the pulling base.

A drive blade lubrication assembly for use in a powered fastener driver (10). The powered fastener driver (10) contains a drive blade (42) which snap-fits with a reciprocating piston (58) by a blade seal (103) assembly. The drive blade lubrication assembly contains a lubricant applying member adapted to apply lubricant to a portion of the drive blade (42); and a lubricant storing device which is in fluid communication with the lubricant applying member. The lubricating storing device is adapted to replenish the lubricant in the lubricant applying member. A powered fastener driver (10) containing a drive blade lubrication assembly is also described. The use of the lubricant storing device in the present invention ensures that lubricant is continuously supplied to the drive blade (42) after long time usage of the powered fastener driver (10), so that friction between the drive blade and the blade seal assembly is minimized.

A power tool, comprising first and second module, removable from the first module, the first and second modules being insertable into one another along an insertion axis defining an insertion direction, the first module having a pressing inhibiting element, moved along with the second module, and a pressing blocking element, the inhibiting element being turnable with respect to the blocking element about the insertion axis between normal and detaching positions, the second module being held against the first module in the normal position and removable from the first module in the detaching position, the blocking element allowing the inhibiting element to be transferred along the insertion axis toward the first module into a pressing position when the inhibiting element is in the normal position, the blocking element blocking the insert fitting from being transferred into the pressing position when the inhibiting element is in the detaching position.

A fastener system comprising one or more fasteners and a fastener tool is disclosed. The fastener tool comprises a housing; an elongate magazine attached to the housing comprising an elongate partial surface between its ends configured to engage a support structure; a fastener carrying mechanism configured to carry the one or more fasteners with receptacles thereof accessible through the elongate partial surface; a pusher comprising a first end member and a second end member, the second end member providing a receptacle; and a location system formed from a receptacle of the one or more fasteners and the receptacle of the pusher second end member, each configured to locate the fastener tool over and in line with an elongate object on the support surface, and a drive system configured to drive a lead fastener to fasten the elongate object to the support surface.

A power tool including a housing and a motor housed in the housing. There is a spring engine housed in the housing and a driver blade driven by the spring engine. Additionally, the power tool holds a pipe clamp configured to be driven into a workpiece by the driver blade.

There is provided a working end for a nail driving tool for use in installing a siding component having a nailing strip. The working end has a body with a front end, rear end, sidewall, and a nail aperture between the front end and the rear end. A first guide is formed by a recess in the front end and is configured to align the nail aperture with the nailing strip by engaging a surface of the siding component. A receptacle is formed in the rear end of the body and is configured to receive the nail driving tool. One or more protrusions on the front end are spaced from the nail aperture. The one or more protrusions are configured to engage the nailing strip and align the nail aperture with a nail-receiving aperture of the nailing strip.
