A fastening tool including a magazine securely and releasably retained on the fastening tool by a cam mounted on one of the fastening tool and the magazine. In a single rotary motion, the cam wedges together the housing member of the fastening tool and the housing member of the magazine, while simultaneously rotating cam lobes into respective chambers formed on the fastening tool and the magazine. The cam rotation and magazine retention system is accomplished without tools.

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.

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.

A spring arm sleeve, with which a joining element of a joining device is positionable and which comprises the following features: a tubular section which is formed by a circumferential or all-round wall, the circumferential wall comprises in the circumferential direction a plurality of U-shaped apertures regularly spaced apart from one another, which form a plurality of one-sidedly fastened spring arms which are inclined radially inwards into the tubular section and extend from a fixed end in a first longitudinal direction.

A control and protection mechanism and a nail gun having the same. The control and protection mechanism includes first and second micro-motion switches, a toggle block, a lock pin, an actuating member, a micro-motion contact and a driving rod. The switch bracket is attached to the main body; the first and second micro-motion switches are fixed on the switch bracket; the toggle block is rotatably attached to the switch bracket, and includes a lock groove, a trigger end and a toggle end. The toggle end is operably coupled to the first micro-motion switch and the trigger end extends into inside the main body such that when the piston moves in the cylinder to a position, the piston pushes the trigger end to prompt the toggle block to rotate and therefore the toggle end to move, thereby causing the first micro-motion switch to change its switch state.

The present invention discloses a fastening device, comprising a main body and a holding part, wherein the main body constitutes a main plane, and the holding part and the main body are rotatably connected to each other; and the holding part comprises a first arm and a second arm, the first arm is provided with a first connection mechanism and a second connection mechanism, the first arm is rotatably connected to the main body via the first connection mechanism, and the second arm is rotatably connected to the first arm via the second connection mechanism. Such a fastening device can be used for the installation of floorings. Not only can the height of a handle be changed, but also the angle at which the handle is held can be changed at the same time. Moreover, the fastening device is further provided with a detachable auxiliary moving device, which can easily move a base during use, but the auxiliary moving device can be removed when it is not needed, which is convenient for packaging and transportation.

A concrete nailer has a cutout defined by a magazine. The cutout is disposed proximate the drive track of the concrete nailer and provides the concrete nailer with sufficient reach to perpendicularly nail a complete range of U-shaped channels or track available to the job site against concrete, even though the magazine accommodates both long and short nails. The concrete nailer has the added ability to nail thick boards like 2×4's to concrete.

The invention relates to a nail device for setting nails into an object, comprising a housing, a setting mechanism for setting the nail along a setting axis, a bolt-guiding element for contacting on the object at a first contact point, in particular a trigger for activating the setting mechanism, a swivelable support foot for contacting on the object at a second contact point, wherein a connecting line between the first and the second contact point and the setting axis span a device plane of the nail device, characterised in that the swivel axis of the support foot is oriented substantially perpendicular to the device plane.

A magazine for use with a fastening tool. The magazine can have a pusher assembly that can be retracted into a recess in the magazine to facilitate loading and reloading of fasteners. The pusher assembly can have a pusher assembly knob which can be reversibly latched to a detent to maintain the pusher assembly in a retracted state. The fastening tool can use a magazine which can be reloaded by a method which has a step of reversibly retracting the pusher assembly into the retracted state to allow for feeding one or more fasteners to the magazine.

The screwing accessory device comprises a receiving box, a rack and a pushing component. The receiving box is for receiving the screwed component. The rack is connected to the receiving box. The pushing component is disposed within the receiving box and is used for pushing the screwed component.
