A locking mechanism for a power tool includes a fixed locking block installed below one end of the support, a fixed bracket installed at the other end of the support, and a locking handle hinged to the fixed bracket via a second pivot. A first pivot is located outside the second pivot on the locking handle, connected to one end of a drive shaft. The other end of the drive shaft is connected to one end of a lower moving plate located inside the support. A sliding locking block is installed below the other end of the lower moving plate. When the locking handle is rotated inward to the locked position, the drive shaft pushes the sliding locking block inward, reducing the distance between the sliding locking block and the fixed locking block, thus locking the support. When the locking handle is rotated outward to the open position, the drive shaft pushes the sliding locking block outward, increasing the distance between the sliding locking block and the fixed locking block, thus releasing the support. This invention features adjustable locking force and stable locking; the locking handle can be folded inward, making it less likely to be touched, ensuring the cutting accuracy and safety of the power tool.

This utility model discloses a breathing trainer with an airway convection structure, including an air cylinder, a lower cover, and an upper cover. The air cylinder has an internal movable chamber containing at least one weight. The weight is spaced from the inner wall of the movable chamber to form a first airflow channel. The air cylinder has a lower opening at its lower end and an upper opening at its upper end, both connecting to the movable chamber. The lower end and upper end of the first airflow channel are connected to both the lower and upper openings. The lower cover covers the lower opening and has an airflow tube. An operating element is located on the end of the airflow tube away from the lower cover. A second airflow channel, connecting the lower opening and the airflow tube, extends through the lower cover. The upper cover covers the upper opening, and the upper cover and air cylinder are spaced apart to form a third airflow channel connecting the upper opening to the outside. This breathing trainer is very clean and hygienic to use and is highly practical.

This utility model belongs to the technical field of aluminum profile production equipment, specifically providing a lifting fixture and device for aluminum profile production. The lifting fixture includes a lifting component and a connecting component. The lifting component is connected to a lifting rope, and the connecting component is rotatably engaged with the lifting component. The lower end of the connecting component extends into an installation cavity and is provided with a connecting end for detachable connection with the mold. In use, the connecting component is directly rotated to screw the connecting end into the threaded hole of the mold. The lifting device is then used to lift the mold to the mold installation position on the extrusion press. The connecting component is then rotated again to separate the connecting end from the mold. The lifting fixture provided in this application replaces the existing separate connection form of lifting ring and hook. Rotating the connecting component allows for connection and separation from the mold, making installation and disassembly simpler and more convenient. The length of the connecting component is longer than that of existing ordinary lifting rings, making it less likely to touch the mold when rotating the connecting component, thus helping to reduce the probability of burns.

The utility model discloses a liftable drawing faucet which comprises a tooth pipe and a water outlet elbow, the water outlet elbow is arranged on the inner side of the tooth pipe in a sleeved mode, a first O-shaped rubber ring is arranged on the outer side of the bottom of the water outlet elbow in a sleeved mode, a first clamping ring is installed on the inner side of the lower portion of the tooth pipe, and a second clamping ring is arranged on the outer side of the bottom of the water outlet elbow in a sleeved mode. The first clamping ring is clamped between the first O-shaped rubber ring and the second clamping ring, a guide inclined face is arranged on the inner side of the lower portion of the threaded pipe, a wear-resisting ring is installed on the inner side of the top of the threaded pipe, and a second buffering rubber ring is arranged at the bottom of the wear-resisting ring. The water outlet elbow is easy to lift, the first O-shaped rubber ring is supported by the first clamping ring to prevent the water outlet elbow from descending, the water outlet elbow is upwards pulled and limited by the second clamping ring, when the water outlet elbow is not used, the water outlet elbow can be pressed downwards, most of the water outlet elbow is retracted below the table top, the occupied space on the table is small, space resources are saved, meanwhile, the water outlet elbow is not prone to being touched, and the water outlet elbow is convenient to use. Usage is convenient and usage experience is good.

The utility model relates to the field of orthodontics of teeth, in particular to an orthodontic appliance. According to the locking bracket, a locking mechanism is arranged in the length direction of an arch wire groove, the locking mechanism comprises a locking plate, locking limiting heads and locking clamps, and the locking limiting heads are arranged at the two ends of the locking plate in the length direction; the locking plate is arranged in the arch wire groove; the locking limiting heads are clamped at the two ends, in the length direction of the arch wire groove, of the main body part; the locking clamp is used for pressing the arch wire and is movably connected to the locking limiting head. The mode of compressing the arch wire is simple and rapid, and operation of a doctor is facilitated; the oral cavity of a patient cannot be touched easily, and the oral cavity of the patient cannot be hurt easily. Compared with the prior art that the arch wire needs to be pressed in a rotating mode, the arch wire can be fixed only by using a tool to act on the locking clamp and pressing the arch wire after the locking clamp deforms, the operation is simple and rapid, the operation of a doctor is greatly facilitated, and the correction efficiency is improved.

A wafer correction device and a wafer correction method are provided. The wafer correction device comprises a rotating table, a lower chuck, an XY-axis moving platform, a measuring sensor, a Z-axis lifting mechanism, an upper chuck and a PLC system. The lower chuck is used to adsorb the wafer, the rotating table is used to drive the lower chuck to rotate, and the XY-axis moving platform is used to drive the rotating table to translate. The measuring sensor is located on the X-axis and is used to measure the distance of the point of the outer peripheral contour of the wafer when rotating into the sensing area of the measuring sensor. The wafer correction method comprises: rotating a first circle to determine and correct the X-axis direction offset distance ΔX between the first rotation center of the rotating table and the center of the wafer, rotating a second circle to determine and correct the Y-axis direction offset distance ΔY between the second rotation center of the rotating table and the center of the wafer, rotating a third circle to verify whether ΔX and ΔY are within the allowable error range, and determining the orientation of the V-shaped notch or straight edge based on the corrected center of the wafer.
