The invention relates to a double-circumference synchronizer with springs. The double-circumference synchronizer comprises a gear hub and a gear sleeve. The gear hub is sleeved on a transmission shaft, the gear sleeve is movably connected with the gear hub by splines, peripheral grooves are formed in the centers of two end surfaces of the gear hub, and an annular neutral positioning spring is arranged in a groove gap between upper and lower spline teeth. Synchronizing rings are connected to axial end surfaces of the gear hub, inner conical surfaces of the synchronizing rings are connected with outer conical surfaces of combination teeth, and annular pre-synchronizing springs are sleeved on protruded structures of the synchronizing rings. The double-circumference synchronizer has the advantages that friction torque among the conical surfaces of the synchronizing rings and the combination teeth can be preliminarily adjusted, so that the gear shifting smoothness of a sped changer can be improved; the synchronizer can assuredly have a neutral position and is compact in structure.

A riding mower comprises a raising and lowering mechanism (30, 33, 100), the raising and lowering control lever (27), and a PTO mechanism (17a, 17b) operated by a clutch lever (29). When the raising and lowering mechanism (30, 33, 100) reaches a predetermined height, a operatively connecting mechanism (5) transmits, to the raising and lowering control lever (27), a return-to-neutral displacement for returning the raising and lowering control lever (27) to the neutral position, and transmits, to the clutch lever (29), a disengaging displacement for returning the clutch lever (29) to the disengage position. A first adjusting operation member (55a) adjusts a triggering displacement at which the raising and lowering displacement is transmitted to the raising and lowering control lever (27) as the return-to-neutral displacement. A second adjusting operation member (55b) adjusts a triggering displacement at which the raising and lowering displacement is transmitted to the clutch lever (29) as the disengaging displacement.

The invention discloses a multifunctional movable surgical instrument disinfection cabinet which includes a disinfection cabinet body, wherein universal wheel devices are symmetrically arranged on thebottom surface of the disinfection cabinet body, a cabinet door opening is formed in the front surface of the disinfection cabinet body, a cabinet door is arranged on the cabinet door opening, a filter board is arranged at the lower 1/3 part inside the disinfection cabinet body, a drying device and an ozone generating device are arranged on the side surfaces of the interior of the disinfection cabinet body, a timing device is arranged in the middle of the upper part of the ozone generating device, an air filtration device and a gas pump are arranged on the side surfaces of the outside of thedisinfection cabinet body, an illumination device is arranged in the middle of the internal upper part of the disinfection cabinet body, a drainage device is arranged on the right part of the bottom of the disinfection cabinet body, an observation port is arranged in the middle part of the cabinet door, and a controller is arranged at the top of the disinfection cabinet body. The multifunctional movable surgical instrument disinfection cabinet has the advantages of simple structure and strong practicability.

The invention discloses a leafrogging device for on-line cold foiling of a printing machine. The leafrogging device comprises an unwinding device, a winding device, two anilox rollers and four groups of driving mechanisms, wherein the unwinding device and the winding device are used for unwinding and winding alumite foil respectively; the anilox rollers are arranged on the pathways that the alumite foil enters and leaves a printing unit respectively, and are arranged between the two side wall plates of the printing machine; each end of the anilox rollers is connected with one group of driving mechanism; the anilox rollers can slide along guide grooves, which are in the two side wall plates of the printing machine, under the driving of the driving mechanisms. The leafrogging device utilizes the characteristic that a roller is free from printing in a neutral position, adopts reciprocating movement of the anilox rollers to control conveying resulting velocity of the alumite foil, and improves usage rate of the alumite foil, that is, cost is reduced effectively and environment is protected while realizing on-line cold foiling; a key part adopts a cam mechanism; the structure is simple; operation is stable.
