A blind rivet setting device and method of setting a blind rivet. The device includes a housing; a pulling mechanism, arranged in the housing, that includes a chuck housing movable in a pulling direction and clamping jaws movable along a clamping distance in the chuck housing; an electric drive, structured and arranged to act on the chuck housing, that includes a control device; an electric battery structured and arranged as an energy source for the electric drive; and a spring structured and arranged in the chuck housing to apply a force to clamping jaws. For each clamping jaw, the chuck housing includes a guide path with a path base obliquely oriented to the pulling direction, and a back of each clamping jaw is supported against its respective path base over the clamping distance.

A power tool for joining a deformable element having a threaded shaft to a workpiece. The joining tool comprising a threaded dowel adapted to receive the threaded shaft and rotatably within the housing. A nose is arranged around the threaded dowel, and the dowel is slidably movable relative to the nose. A motor drives a drive train to rotate the threaded dowel. A hydraulic system drives another drive train to move the threaded shaft and compress the deformable element. The joining tool includes a sliding unit. The nose is attachable to the sliding unit, and in an attached position the nose is slidably connected to the housing so that the hydraulic system may move the nose axially to compress the deformable element.

A fastening tool includes a motor, an anvil, a pin-gripping part, a magnet having the north pole and the south pole aligned in a front-rear direction and configured to move integrally with the pin-gripping part in the front-rear direction, a first magnetic sensor having a first sensing surface, a second magnetic sensor having a second sensing surface and disposed rearward of the first magnetic sensor, and a control device configured to move the pin-gripping part rearward based on a detection result of the second magnetic sensor and to move the pin-gripping part forward based on a detection result of the first magnetic sensor. The first and second magnetic sensors are unipolar detection type sensors configured to detect a same specified pole of the magnet. Orientations of the first sensing surface and the second sensing surface relative to a movement axis of the magnet are opposite to each other.

A rivet module is provided to join at least two sheets of base materials in a solid state, the rivet module including: i) a shank portion to be mounted on a reciprocal and rotatable joining tool; ii) a base material friction portion that is integrally connected to the shank portion and drills through the base materials as the joining tool causes the base material friction portion to be rotated while applying pressure to the base materials; and iii) a base material fastening portion that is fixedly fitted to the shank portion, supports the base material friction portion, and is fastened to the base materials through a thread formed on the outer peripheral surface thereof.

An apparatus for mounting a blind rivet, configured to mount the blind rivet having a rivet body and a mandrel on a board, may include a rivet holder accommodating a mandrel therein and pressing a rivet head towards the board, a mandrel holder positioned inside the rivet holder and moving separately from the rivet holder to hold and pull the accommodated mandrel, and an impactor positioned inside the rivet holder to accommodate the mandrel holder therein and applying pressure to the mandrel holder holding the mandrel, thus lifting the mandrel holder together with the mandrel.

A fastening structure includes a blind rivet and a nut. The blind rivet includes a rivet body having a hollow sleeve, a rivet head at the end of the sleeve and a through-hole; and a mandrel having an elongated stem and a mandrel head. The nut is positioned around the sleeve side end of the rivet body and the mandrel head and abuts one of the workpieces. The end portion of the sleeve is enlarged by the mandrel head and is embedded in the internal screw threads of the nut. The workpieces are thus fastened between the nut and the rivet head.

A blind pull type fastener includes a pin, a sleeve, a collar, and a bulb-forming portion. The pin includes a head. The pin is pulled so that the head applies force to the bulb-forming portion. The bulb-forming portion is deformed to form a bulb. The collar is deformed into a void of the sleeve. The pin includes locking rings. The collar is deformed to lock with the locking rings.

A fastener installation tool and method for interference fit, said fastener (10) comprising a head and a grasping element, said tool comprising a first body (30) extending along a first main axis and having: —at least one load-reacting surface, of which one also constitutes a surface for the application of a load; —a load transmission surface, and—a housing extending along the first main axis from a first end of said first body, said housing being extended along the first main axis by a drilling extending from said housing as far as a second end of said first body. According to the invention, the load transmission surface is situated at the second end of the first body (30) and extends perpendicular to the first main axis, said load transmission surface being dimensioned to be able to bear simultaneously on the head and on the insert clamp.

An objective of the present invention is to attach an attached member to a resin panel with less man-hours. According to the present invention, provided is a manufacturing method of a resin panel including an attaching step. In the attaching step, an attached member is attached to a surface of a resin molded body by arranging a rivet body provided on a blind rivet in a concave portion formed on the surface, tearing a part of the rivet body to enlarge a diameter of the part of the rivet body, and allowing the part of the rivet body to penetrate a wall surface of the concave portion.

A power tool includes a motor and a gear speed reducer. The motor has a motor shaft that is rotatable in a normal direction and in a reverse direction. The gear speed reducer is operably coupled to the motor shaft. The gear speed reducer is configured such that a reduction ratio of the gear speed reducer is changed in response to a change of a rotation direction of the motor shaft.
