A method of coupling or decoupling a tool of a rotary-drive sub-assembly and a tool retainer of the rotary-drive sub-assembly includes rotationally anchoring the tool to a first tool-change member, rotatably coupled to a base, by engaging a tool-change-engagement portion of the tool with a first tool-engagement portion of the first tool-change member. The method also includes causing relative rotation between the tool and the tool retainer.

A wall anchor fastening and releasing tool having a tool body forming a slide housing, a handle rigidly projecting from the slide housing, a slide arranged inside the slide housing, and a first lever pivotally connected to the handle and arranged to displace the slide in the slide housing between a first position and a second position. When the first lever is in the first position, a screw gripping end of the slide is adjacent a first housing end, and, when in the second position, the screw gripping end of the slide is retracted in the slide housing and a screw pushing end of the slide is adjacent a second housing end, the screw gripping end of the slide being arranged to grip underneath a head of a wall anchor center screw, and the second housing end being arranged to grip underneath a wall anchor collar.

The invention relates to a riveting tool for setting blind rivet nuts and/or blind rivet screws with a drive piston hydraulically adjustable between a starting position and an end position and a pull rod operationally connected with the drive piston and adjustable between a rivet receiving position and a setting position. In order to provide a riveting tool with a hydraulically driven drive piston, which has a simple and good adaptability for the blind rivet screws and/or blind rivet nuts to be set, it is provided that a coupling unit, a tractive tool adjusted for the blind rivet nut and/or blind rivet screw as well as the pull rod are designed for the form-fitting connection of the pull rod with the tractive tool, which is releasable in the direction of the longitudinal axis and in the circumferential direction.

Tooling is held within the nose of a rotary punch and as the tool is rotated and forced against a workpiece a fastener within the tool becomes affixed to the workpiece. The tools have displacers which non-destructively deform and reshape the workpiece without any loss of workpiece material. The tools have various types of displacers including; tapered and arcuate displacers which act in concert to progressively act upon the workpiece; spherical displacers which may be fixed or rotatable such as caged ball bearings; and a full-circle displacer ring which wobbles as it presses against the workpiece. In the case of fixed spherical displacers, a multi-stroke method can be employed where the tool is rotated after each stroke in a group of installation strokes.

The invention provides device and method for removing a basket for a washer. The device comprises a structure for attaching to a basket disposed on a shaft of a washer, and a component threadably movable with respect to the structure to move the basket with respect to the shaft. The method comprises attaching the structure to a basket disposed on a shaft of a washer, and rotating the threadably movable component with respect to the structure to axially engage the shaft and move the basket with respect to the shaft.

The present invention discloses a gecko gun, which includes a housing with a left handle on the bottom, and a right handle. The mentioned left handle and right handle are all covered by a handle housing. The mentioned cover housing is installed with a U-shaped seat at the top end. The top end of the right handle is rotated with the top end of the housing through a spindle. The top end of the right handle is installed with a link mechanism, which is covered by the mentioned housing and fixed to the housing via screws. The link mechanism includes a first linkage assembly linked to the top end of the right handle and a second linkage assembly connected to the first linkage assembly, and the second linkage assembly is used to drive the U-shaped seat to shift forward and backward. Thereby the designed gecko gun will help achieve the effect of energy saving.

A rivet for blind fastening may include a screw with a handling element, a break groove, a head separated from the handling element by the break groove, and a threaded part. The rivet may also include a sleeve with a collar and a tubular shank having an internal thread intended to come into engagement with the threaded part of the screw. The handling element includes a first handling portion able to guide introduction of the rivet in a setting tool, and a second handling portion able to transmit a torque, the two handling portions being separated by a blocking portion able to limit an axial movement of the rivet in a setting tool. A setting nose may be used for installing such a rivet, and the rivet, setting nose and a setting method can be used in the assembly of aircraft structures.

A construction support structure contains: a plurality of first hollow posts, plural second hollow posts, and at least one platform. Each first hollow post includes at least one groove, and each groove has a first width section and a first narrow section, wherein a horizontal width of the first width section is more than the first narrow section. Each second hollow post includes two locking protrusions, and a distance between two sides of each locking protrusion is more than a distance between a top end and a bottom end of each locking protrusion, wherein each locking protrusion has a connecting section, a diameter of which is less than the distance between the two sides of each locking protrusion and the distance between the top end and the bottom end of each locking protrusion, and the connecting section corresponds to the first narrow section of each first hollow post.
