A dual-shaft synchronous transmission fixing device has a simplified structure and minified volume. The gap between the rotary shafts can be changed or adjusted according to the transmission specification so that the electronic device can be thinned and lightweight. The fixing device includes a driver and a reactor respectively disposed on a first shaft and a second shaft and a link unit engaged with the driver and the reactor, whereby the first and second shafts can be synchronously rotated. The fixing device further includes a main fixing plate and a subsidiary fixing plate having identical structures. The main fixing plate and the subsidiary fixing plate are disposed on the first and second shafts. Each of the main fixing plate and the subsidiary fixing plate has a base section for together pivotally connecting with the link unit.

A pneumatic turbine motor air chamber drives a pneumatic turbine to rotate through compressed air. The pneumatic turbine has a ring extended from inside thereof that has a plurality of barriers and forms a housing space to hold a speed regulator. The pneumatic turbine also has an air intake coupling hole leading to the housing space and at least one air discharge vent communicating with an air passage to discharge the compressed air. The ring is integrally formed with the pneumatic turbine to enhance operation steadiness of the pneumatic turbine.

The invention relates to a steel plate lifting and conveying mechanism, and the mechanism comprises positioning plates fixedly arranged at the two sides of a conveying support; a conveying device is assembled between the positioning plates at the two sides, and driving air cylinders are fixedly arranged at the bottoms of the positioning plates, wherein driving shafts of the driving air cylinders penetrate through the positioning plates to abut against the conveying device and are used for driving the conveying device to ascend and descend. According to the invention, the mechanism is simple instructure and convenient to operate; the driving air cylinder is used for driving the conveying device to vertically ascend and descend, and the inclination is avoided, so the stability and safety ofsteel plate conveying of the conveying device are improved; the conveying device can be lifted to different height positions through the driving air cylinder and can be accurately positioned, and thelifting process is stable and reliable.

The invention relates to an H-shaped steel conveying and jacking mechanism which comprises a base and a steel plate conveying mechanism arranged on the base. A front material blocking mechanism and arear material blocking mechanism which are used for positioning H-shaped steel are arranged at the two ends of the base. The front material blocking mechanism comprises a front bottom plate fixedly arranged on the base, and a front supporting plate is vertically and fixedly arranged on the front bottom plate. A front positioning plate is vertically arranged on the front supporting plate, the frontpositioning plate is assembled on the steel plate conveying mechanism, a front mounting plate is fixedly arranged on the inner side of the front positioning plate, front supports are symmetrically and fixedly arranged on the front mounting plate, and a front material blocking rod is rotatably connected to the front supports. A front driving mechanism used for driving the front material blocking rod to move up and down is arranged on the front bottom plate. The H-shaped steel conveying and jacking mechanism is simple in structure and ingenious in design, and by means of the front material blocking mechanism and the rear material blocking mechanism, H-shaped steel needing to be machined can be positioned on the steel plate conveying mechanism, and convenience, safety and accuracy are achieved.

The invention relates to a gushing arm assembly which is used for a dishwasher and comprises a gushing arm seat; a supporting seat which is connected to the gushing arm seat; a first gushing arm which is arranged on the supporting seat in a sleeving manner and is communicated with the gushing arm seat; a first bearing which comprises a first sliding ring and a second sliding ring which can slide relative to each other; the first gushing arm is provided with a first water inlet and a first flow guide pipe located on the periphery of the first water inlet, the first sliding ring is arranged on the outer wall of the first flow guide pipe in a sleeving mode, and the second sliding ring is arranged on the inner wall of the supporting base and located outside the first sliding ring, a first annular protrusion is arranged on the inner wall of the first sliding ring, a first annular groove is formed in the outer wall of the first flow guide pipe, and / or a second annular protrusion is arranged on the outer wall of the second sliding ring, a second annular groove is formed in the inner wall of the supporting seat, and the first gushing arm can rotate relative to the gushing arm seat through the first sliding ring and the second sliding ring. According to the gushing arm assembly, the first gushing arm is connected with the gushing arm base through the first bearing, and therefore friction resistance is reduced.
