The telescopic ends of the electric telescopic rods are connected to limiting plates. The output shaft of the drive motor in the processing component is connected to a cam. Rollers abut against both sides of the cam, and the rollers rotate in the middle of a connecting block. Guide blocks are located on both sides of the connecting block and slide above them. The output shaft of the rotary motor of the transmission component is connected to a bevel gear set. A transmission rod passes through the other side of the bevel gear set and connects to a pulley. The two pulleys are connected by a conveyor belt located inside the baffle. A sprocket is located near the bevel gear set on the side of the pulley, and the two sprockets are connected and meshed by a chain. A cutting blade is bolted to both ends of the connecting block. A processing door is located on the side of the baffle near the processing component, and the cutting blade slides inside the processing door for cutting.

The utility model discloses an air path adjusting system and a vehicle, and the air path adjusting system comprises an air suspension which is provided with an air supply unit; and the battery pack is provided with a containing space, and the containing space selectively communicates with the air supply unit. According to the air path adjusting system, the air suspension is provided with the air supply unit, and the battery pack is provided with the containing space and is selectively communicated with the air supply unit through the containing space, so that air pressure balance inside and outside the battery pack is realized. Meanwhile, air pressure balance inside and outside the battery pack is achieved through the air supply unit of the air suspension, other devices do not need to be additionally arranged, and the size of an air path adjusting system is reduced. Besides, an internal circulation closed route is formed between the accommodating space and the gas supply unit, so that the gas entering and exiting the accommodating space of the battery pack is free of impurities and is not polluted by the outside, and the reliability of the battery pack and the gas path adjusting system is effectively improved.

The utility model relates to a Y-axis split type protection structure which comprises a sliding table, the sliding table is provided with a Y-axis guide device, and guide grooves are formed in the two sides of the Y-axis guide device. The split frame structure is arranged on the sliding table and comprises a supporting plate, two L-shaped connecting plates arranged on the two sides of the main plate and a pressing plate connected with the two L-shaped connecting plates, the pressing plate is arranged above the first supporting plate, the other ends of the two L-shaped connecting plates are connected to the guide groove in a sliding mode, and the two L-shaped connecting plates are connected with the pressing plate in a sliding mode. The L-shaped connecting plate, the supporting plate and the pressing plate are arranged at intervals to form a mounting groove and a protective cover. The split frame structure has the advantages of being high in structural stability and good in dustproof effect, the pressing plate serves as a part of the split frame structure and is placed above the L-shaped connecting plate and the supporting plate, certain pressure is applied to the pressing plate, looseness or displacement caused by vibration is prevented, and the protective cover can play a dustproof role.

A kind of wood fiber cellulose sponge processing mould, the inside of sponge bearing table is equipped with wood fiber cellulose sponge, the size of sponge bearing table is adapted according to the size of wood fiber cellulose sponge, there is interval between sponge conveying platform and sponge bearing table, the lower end of sponge conveying platform is equipped with fixed block and limiting U-shaped groove fixed by welding, a pair of fixed blocks are arranged in total in the lower end of sponge conveying platform, two limiting U-shaped grooves are arranged in total in the lower end of sponge conveying platform, and fixed block is located in the two limiting U-shaped grooves.This utility model can realize the positioning of wood fiber cellulose sponge with different sizes and shapes by setting limiting U-shaped groove below sponge conveying platform and using sliding bracket for sliding adjustment.Meanwhile, the position of sliding bracket is further fixed by first butterfly bolt on fixed block, ensuring the stability during conveying, adapting to the processing needs of wood fiber cellulose sponge with various specifications, improving equipment versatility;Reducing manual intervention, reducing operation difficulty and improving production efficiency.

The invention discloses a watertight suite of a handle part connector, a waterproof connector and an endoscope, and relates to the technical field of endoscopes. The watertight suite of the handle part connector comprises a first pipe body, a second pipe body, a reset structure and a sealing piece. The second pipe body is embedded in one end of the first pipe body in a sliding mode, the second pipe body and the first pipe body jointly form the installation space in a surrounding mode, the sealing piece is arranged in the installation space, and the radial size of the sealing piece is expanded after the axial size of the sealing piece is compressed so that the first pipe body and the second pipe body can be sealed. In this way, water can be prevented from entering the electrical element installed in the watertight external member of the handle part connector. And at the moment, the electrical element and the watertight external member of the handle part connector can be directly soaked and disinfected, so that the disinfection process is simplified, and meanwhile, the electrical element arranged in the watertight external member of the handle part connector is prevented from being polluted by the outside.

The utility model provides a nursing tray, and relates to the technical field of nursing trays, the nursing tray comprises a tray main body, the rear side edge part of the top end surface of the tray main body is rotatably provided with a sealing cover plate, the sealing cover plate used for sealing a tray groove is added on the basis of a traditional tray, so that the sealing of the tray groove is realized through the sealing cover plate; the medical instruments and the medical supplies stored in the tray groove are prevented from being attached by germs and the like possibly contained in the air, pollution is avoided, the state of the closed cover plate is automatically monitored, and when the closed cover plate is not in a closed state and exceeds a certain time limit, corresponding buzzing warning is automatically started, so that the medical instruments and the medical supplies are prevented from being polluted. The medical nursing tray solves the problems that most existing nursing trays are of an exposed structure, medical instruments and medical supplies placed in the existing nursing trays are exposed, germs and the like possibly contained in outside air are attached to the medical instruments and medical supplies placed in the existing nursing trays, and the medical instruments and medical supplies are polluted.
