A electrical connector for removably engaging a welder to a spot welding tool having a first arm in a pivoting engagement to a second arm. The connector features an electrically conductive member engaged to or forming a powered translating shaft of a welder which is surrounded by a housing. The connector engages within a passage formed in a coupling to communicate forward and rearward movement and electric current to a first arm of a spot welding tool.

The present disclosure relates to a detachable quick connection apparatus for photographic equipment and a photographic equipment assembly. The apparatus comprises a locking means and a connection assembly, the locking means comprising a fixed seat provided with at least one through hole and a driving means rotatable relative to the fixed seat, at least one latching member being provided between the fixed seat and the driving means, the connection assembly is provided with an engagement slot which is engaged by the locking member, the locking means comprises a locking member provided in the driving means and a locking spring, the locking member comprises a locating member and a first elastic member which are mounted in the driving means, the locating member is at least partially engaged between the fixed seat and the driving means at the releasing position so that the driving means is stopped at the releasing position.

An elongate connector for subsea connection of cables and the like to wind turbine generators has a plurality of locking elements arranged on ramp surfaces and held in a plurality of cages on the connector. The cages are moveable to move the locking elements along the ramp surfaces between an engaged position and a disengaged position and the plurality of cages are moveable independently of each other. A release collar is provided, which can move all the cages simultaneously to the disengaged position, in order to allow removal of the connector.

An actuator system includes a motor having a system of rotating shafts, a conversion arrangement including one of the rotating shafts and converting rotational motion to elongation, and a brake arrangement having one of the rotating shafts as a brake shaft, an electromagnet, at least one brake chamber formed between the brake shaft and an associated brake wall, and a magnetoactive brake member for each brake chamber. Each brake chamber includes a free-wheeling region for receiving the respective brake member. Each brake chamber includes a braking region with a decreasing radial distance between wall and rotation axis. Each brake member is arranged movably in the respective brake chamber in such a way that frictional contact can be formed with the brake shaft and brake wall. In an activated state, the electromagnet is configured to bring each brake member into the associated free-wheeling region.

According to some embodiments, an adjustable assembly for a bicycle includes a lower tubular support configured to be attached to a bicycle frame; an upper tubular support configured to be attached to a bicycle saddle; an expansion portion support member positioned within an interior space of the lower tubular support; an expansion portion disposed at an upper end of the expansion portion support member; and a resilient member configured to provide an upwardly-directed force to the upper tubular support to provide movement of the upper tubular support away from the lower tubular support.

A bicycle seat post assembly includes a lower seat support secured to the frame, an upper seat support secured to the seat and movable relative to the lower seat support, and an adjusting mechanism coupling the lower seat support to the upper seat support. The adjusting mechanism includes a powered actuator engageable with both the lower seat support and the upper seat support and configured to move the upper seat support relative to the lower seat support, and a coupling device selectively connecting the powered actuator to one of the lower seat support or the upper seat support. The coupling device has a connected state wherein the powered actuator is operatively connected to the one of the lower seat support or the upper seat support and a disconnected state wherein the powered actuator is operatively disconnected to the one of the lower seat support or the upper seat support.

A telescopic mechanism includes a top tube, a bottom tube, a supporting tube, at least one stroke tube, at least one first positioning tube, at least one second positioning tube, and a control assembly. The bottom tube is slidably disposed around the top tube. The supporting tube is disposed in the top tube. The at least one first positioning tube and the at least one second positioning tube are disposed in the top tube. The control assembly is connected to the bottom tube and has a positioning base. The positioning base is movably disposed in the at least one stroke tube, the at least one first positioning tube, and the at least one second positioning tube. When the positioning base is fastened with the at least one first positioning tube, the top tube is moved toward a first direction relative to the bottom tube to form a first length.

The present disclosure may include a leg comprising first and second tubes, the first tube inside of the second tube, a lock mechanism within the second tube, the lock mechanism including a plug, a ramp, and bearings configured to roll along the ramp and contact the ramp and at least an interior wall of the first tube such that as the one or more bearings contact the ramp and the interior wall of the first tube, motion of the second tube relative to the first tube is inhibited, and a third tube inside of the second tube, and in response to the third tube being substantially disposed within the second tube, a proximate end of the third tube configured to push the one or more bearings towards the plug, reducing the interference of the one or more bearings with the interior wall of the first tube.
