A component has a base bushing, which has a first axial end and an opposite second axial end and a first inner diameter, wherein the base bushing is equipped with a first internal thread with a first thread direction, and has a fastening bushing, which has a third axial end and an opposite fourth axial end and a second inner diameter. The fastening bushing is equipped with a second internal thread with a second thread direction which is opposite to the first thread direction, wherein the second inner diameter is smaller than the first inner diameter and the base bushing and the fastening bushing are separate elements and are arranged coaxially with respect to one another in the component. Alternatively, the base bushing and the fastening bushing are formed as a single piece.

An installation tool for a fastener of the pull screw type, comprising a breakable gripping element includes a body, a first sleeve movable axially and rotationally in the body that can drive the gripping element, a second sleeve movable axially in the body and immovable in rotation, and a driving device provided with a turning shaft. The shaft comprises a first free wheel for driving the first sleeve in rotation, a second free wheel, and a driving element positioned coaxially around the second free wheel. The driving element cooperates using a helical link with the second sleeve. The first free wheel drives the first sleeve in rotation in a first rotation direction of the shaft. The second free wheel brings the driving element in rotation in a second rotation direction of the shaft to move the second sleeve axially, allowing full setting in a single operating sequence.

A tool-change station includes a base, and a first tool-change member that is coupled to the base and is rotatable relative to the base. The first tool-change member includes a first tool-engagement portion, geometrically complementary with a tool-change-engagement portion of a tool of a rotary drive.

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 tool-change station includes a base, and a first tool-change member that is coupled to the base and is rotatable relative to the base. The first tool-change member includes a first tool-engagement portion, geometrically complementary with a tool-change-engagement portion of a tool of a rotary drive.

A rotary-drive sub-assembly includes a tool, a tool retainer, and a retaining member. The tool includes a fastener-engagement portion, a first threaded portion, and a tool-change-engagement portion between the fastener-engagement portion and the first threaded portion. The tool retainer includes a body. The body includes a symmetry axis, a second threaded portion and a key. The second threaded portion is configured to be threadably fastened with the first threaded portion of the tool so that the tool is rotationally anchored relative to the body of the tool retainer about the symmetry axis and is translationally anchored relative to the body of the tool retainer along the symmetry axis. The key is fixed relative to the second threaded portion. The retaining member is removably coupled to the body at a fixed location.

A method of threadably coupling a first fastener with a second fastener using a rotary drive including a tool. The method includes rotationally anchoring the second fastener relative to the tool by co-axially urging a fastener-engagement portion of the tool against the second fastener and rotating the tool relative to the second fastener using a socket of the rotary drive until the fastener-engagement portion of the tool mates with a receiving portion of the second fastener, receiving the first fastener within the socket of the rotary drive co-axially with the fastener-engagement portion of the tool, and rotating the first fastener with the socket of the rotary drive relative to a housing of the rotary drive to cause the first fastener to threadably engage the second fastener.

The present invention discloses a manual rivet tool, comprising a first handle assembly, a second handle assembly, a force amplification pulling mechanism, a planetary accelerating rotating mechanism and a quick replacement mechanism; the first handle assembly is fixed to the force amplification pulling mechanism; the second handle assembly is disposed on the force amplification pulling mechanism; the first handle assembly and the second handle assembly act on the force amplification pulling mechanism cooperatively to drive the force amplification pulling mechanism to output a pulling force; a threaded brace rod is fixed to the end of the force amplification pulling mechanism through the quick replacement mechanism, and the force amplification pulling mechanism outputs the pulling force to the threaded brace rod to act on a rivet nut; and the planetary accelerating rotating mechanism is engaged on the upper end of the force amplification pulling mechanism, and the planetary accelerating rotating mechanism drives the threaded brace rod to rotate rapidly by means of the force amplification pulling mechanism. The present application may complete manual riveting efficiently, and the tool is light in structure, convenient to carry, strong in pulling force, labor saving in operation and high in working efficiency.
