In order to improve ease of maintenance of an aircraft passenger seat, the aircraft passenger seat 100 is adapted to be changeable between an upright position and a bed mode position at which the backrest is folded forward. A mechanism for locking the seat at each of the positions is provided with lock pins 350 provided on both sides of the backrest, a handle unit 200 mounted to a rear face of the backrest, and two wires 300 for connecting the handle unit 200 and the lock pins 350. A structure for connecting the wires 300 to the handle unit 200 is improved to facilitate the maintenance of the wires and to make the handle unit lightweight.

A rectangular stage includes a deck supported by a frame and removable legs. The legs insert into a corner receiving assembly below the stage deck at each corner. The leg receiving assembly includes a cylindrical socket into which the top of the leg inserts. The leg receiving assembly also includes a retaining linkage that extends through a slot in the side of the socket and engages the leg. The retaining linkage also includes a manually actuatable latch coupled to the cam to maintain the cam in engagement with the leg.

A process of making a wear-resistant actuating lever is disclosed. The wear-resistant actuating lever includes a lever body made of metal and an integrally molded cover layer made of a polytetrafluoroethylene-based material. The lever body includes a head segment having an upper major surface, a cam-forming surface, a through hole, and at least one upper concavity formed in the upper major surface. The integrally molded cover layer covers on the head segment and is molded thereon using plastic injection molding, and includes an upper portion covering an upper major surface, a cam portion covering a cam-forming surface, and an upper protuberance portion in the upper concavity.

The present invention provides a fixing bracket of a sprinkler for safely fixing and easily mounting and separating a reducer of a sprinkler. The fixing bracket has a body having holes for mounting the reducer, and a pressing lever pressing the bar to bring the bar in contact with the reducer in a space inside the body, in which the body has a pair of walls facing each other and having the holes, respectively, and a bridge connecting the walls, and the pressing lever is turned around a hinge shaft at a first side of the body and presses the bar through an opening formed through the bridge when being turned.

A power tool is provided with a telescopic pole including a first pole configured to telescopingly move in an out of a second pole. A locking mechanism is provided including a first section configured to connect to the second pole and a second section configured to connect to the first pole. The first section includes a sheaf mountable on and surrounding at least part of the second pole, a resilient tab connected to the sheaf, and a catch formed on the tab. The catch is configured to locate within the recess of the second pole when the sheaf is mounted on the second pole.

A tripod for video-photographic equipment, includes: at least one leg having a first, a second and a third section that engage so as to axially slide in a telescopic manner one after the other; a first clamping device that is provided between the first and the second section and a second clamping device that is provided between the second and the third section, an actuating element that is connected to the first clamping device, a transmission element that connects the first and the second clamping device such that the movement of the first clamping device causes the second clamping device to move in a similar manner so that said first and second clamping devices simultaneously clamp and release, and an adjustment member that is provided at the first clamping device in order to adjust the second clamping device via the transmission element.

Telescoping pole systems and clamps thereof are described. The clamps include a body having one or more pin extensions and one or more locking extensions. The pin extensions and the locking extensions are arranged in an alternating manner. A pivot handle is operably connected to the body and has a lever arm that extends from an offset hinge, the offset hinge defining a hinge axis. A pivot pin passes through the one or more pin extensions of the body and the offset hinge of the pivot handle. The pivot pin defines a pivot axis. The hinge axis and the pivot axis are parallel but offset from each other and the one or more locking extensions are arranged to be actuated by the offset hinge as the pivot handle is rotated about the pivot axis of the pivot pin. The poles of such systems may be multi-lobed.

The present invention disclosed a paddle, which includes a blade and a pole that connects to the blade. The pole consists of a first rod and a second rod capable of entering and moving within; with one end of the second rod connected to the first rod and able to move simultaneously. Wherein, the material of the first rod within the pole is different from that of the pole, and the paddle is less likely to break instantaneously.

The disclosure provides an operating rod assembly and a string trimmer. The operating rod assembly includes a first rod provided with a first limiting piece, a second rod provided with a second limiting piece and a connector for connecting the first rod and the second rod. An outer diameter of the second rod is smaller than an inner diameter of the first rod; the first limiting piece and the second limiting piece are matched to limit the relative rotation angle between the first rod and the second rod. When the connector is in a locking state, two ends of the connector respectively lock the first rod and the second rod; when the connector is in a loosening state, the connector releases the second rod or the first rod, and the first rod and the second rod can rotate and stretch relative to each other.

An apparatus for cleaning swimming pools, cement finishing tools, ceiling wire applications, and the like, comprising a first tube having a first end with a collar housing and a first locking assembly with a first collar housing. The second end of the first tube being configured for attaching a tool thereto. An end tube with a first end having a second locking assembly and a second collar housing, is slidably connected to a decagon shaped inner tube having a first end and a second end. The first end of the inner tube being secured to the first tube by the first locking assembly, and the second end being secured to the end tube by the second locking assembly.
