A central bidirectional rotation locking mechanism for a folding tent includes a lock rod, an upper lock plate, and a lower lock plate assembly. The lower lock plate assembly includes a first lower plate, an unlocking plate, and a second lower plate. An elastic locking member and an unlocking mechanism used to control the elastic locking member to perform locking are disposed in the unlocking plate. The elastic locking member is used to lock the lock rod, and the unlocking plate is capable of bidirectional rotation. When the unlocking plate rotates, the unlocking mechanism is enabled to unlock the elastic locking member and the lock rod.

The invention discloses a packaging box for living bags. The packaging box comprises a packaging box body, wherein an installing rod is movably arranged on the inner wall of the bottom side of the packaging box body; a first winding shaft is fixedly arranged on the top of the installing rod; a limited groove is formed in the top of the first winding shaft in a vertical direction; a limited rod ismovably arranged in the limited groove; first sliding chutes are formed in the inner walls of the two sides of the limited groove; first sliding blocks are arranged in the two first sliding chutes ina sliding manner; and one sides, close to each other, of the two first sliding blocks are respectively and fixedly arranged at the two sides of the limited rod. As the distance between the first winding shaft and a second winding shaft is convenient to adjust, the packaging box is suitable for living bags of different sizes; and meanwhile two fixed plates can fix the living bags of different diameters and can enable the first winding shaft and the second winding shaft to rotate conveniently and stably, so that the packaging box body is relatively convenient to use and meets the requirements ofpeople.

A reproducing apparatus includes a reading unit configured to generate a reproduced signal containing information data recorded in a track using a reflected light of an optical beam, a clock generation unit configured to generate a clock having a frequency associated with a wobbling cycle of the track, and a control unit configured to detect a phase difference between the reproduced signal and the clock, and to control the clock generation unit using the phase difference detection result.

A magnetic recording / reproducing device of the present invention includes: a loading motor for driving a mechanism section; a holder section for maintaining the loading motor at a prescribed position; a worm gear rotatable along with a rotation shaft of the loading motor; and a worm gear bearing member integrally formed with the holder section, the worm gear bearing member being in contact with a tip of the worm gear, the worm gear bearing member includes a first deflection portion deflectable along a thrust direction along a rotation axis of the worm gear and a second deflection portion deflectable along a radial direction to the rotation axis of the worm gear, and force is generated at the tip of the worm gear along the thrust direction thereof by simultaneously deflecting the first and second deflection portions so as to define a position of the worm gear along the thrust direction thereof.

The invention provides a rust removal guiding device, and belongs to the technical field of steel bar truss machines. The device comprises a dust removing mechanism, a returning mechanism and a rust removal clearance adjusting mechanism; a first rust removing wheel of the rust removing mechanism is rotatably arranged at one side of a first rust removing wheel support; a second dust removing wheel is rotatably arranged at one side of a second dust removing support; a first sector gear connected with a first rotating shaft is engaged with a second sector gear which is connected with a second rotating shaft; a cylindrical sliding block of the returning mechanism is arranged in a fixing support by sliding leftwards and rightwards; a left returning spring is arranged between a left adjusting plug and the cylindrical sliding block, and while a right returning spring is arranged between the right adjusting plug and the cylindrical sliding block; a clearance adjusting plate of the dust removal clearance adjusting mechanism can swing up and down about a hinging point at the left end; the lower end of a compressing lead screw is in coaxial threaded connection with the second rotating shaft; a butterfly gasket, an adjusting spring and a locking nut are arranged at the upper end of the compressing lead screw. The rust removal guiding device is small in size, and can effectively remove rust on a steel bar.

The invention discloses a pipe sealing performance testing device, comprising a bottom plate, a top of the bottom plate is fixedly connected with a mounting frame, and both sides of the top of the inner cavity of the mounting frame are fixedly connected with a first cylinder, The output end is fixedly connected with an adjustment frame, the two sides of the top of the bottom plate are fixedly connected with a hydraulic cylinder, the output end of the hydraulic cylinder is fixedly connected with a placement arc frame, and both sides of the inner cavity of the installation frame are fixedly connected with a drive frame. Through the use of the first air cylinder, the second air cylinder, the hydraulic oil cylinder, the electromagnetic valve and the air pressure sensor, the present invention makes the equipment use a higher degree of automation, which is convenient for the user to operate and use. The use of the device can be more convenient for the fixed use of the equipment, and the use of the clamping device makes the use of the equipment more flexible, facilitates the sealing of pipes of different specifications, and improves the applicability of the equipment in use.

A control apparatus for an outboard motor mounted on a boat and equipped with a transmission having at least forward first and second speed gears and a reverse gear. The apparatus functions as a rudder angle detector that detects a rudder angle, a slip ratio detector that detects a slip ratio, and a transmission controller. The transmission controller controls the operation of the transmission to select one of the gears based on the detected engine speed or the detected slip ratio according to a comparison between the detected rudder angle and a predetermined angle.
