A large-angle rotation robot joint includes a thigh and a lower leg. The lower end of the thigh is hinged to the upper part of the lower leg to form a knee joint. A through hole at the upper end of the thigh serves as a hip joint. The lower leg is L-shaped, consisting of a long arm and a short arm. The hinge point between the lower leg and the thigh is at the junction of the long and short arms. A primary link is hinged to the thigh, and the other end of the primary link is hinged to a secondary link. The other end of the secondary link is hinged to the short arm of the lower leg. A hydraulic cylinder is hinged between the thigh and the primary link, with the hinge point between the hydraulic cylinder and the thigh located above the hinge point between the primary link and the thigh. This invention uses a four-bar linkage to meet the needs of large-angle rotation of the hydraulic cylinder-driven robot joint; it uses a double thigh arm design to facilitate component installation and avoid interference; and the left and right drive components are symmetrically arranged for balance.

This invention discloses a tilting and straightening device for large-tonnage components, relating to the field of component tilting technology. The device includes a frame, a first L-shaped hinged frame, a second L-shaped hinged frame, and a hydraulic cylinder. The short arms of the two hinged frames are nested and interlocked on the same horizontal plane. The device has a gravity-pneumatic linkage support system on the inner surfaces of the second short arm and the second long arm, and a mechanical locking mechanism between the two arms. The gravity-pneumatic linkage support system includes at least one first elastic pad, at least one second elastic pad, and a pneumatic circuit assembly connecting the two. The first elastic pad is vertically movable and protrudes from the surface of the second short arm, while the second elastic pad is vertically movable and flush with the surface of the second long arm in its natural state. When the component is pressed against the second short arm, the first elastic pad retracts, and gas pushes the second elastic pad to protrude and fill the gap between the side of the component and the long arm, preventing the component from sliding and colliding during tilting.

This application provides a Z-shaped guided osteotomy device for hallux valgus correction. The guided osteotomy device includes a Z-shaped integrated guide blade, a pair of alignment channels, and a handle. The guide blade includes a long arm segment and short arm segments at both ends of the long arm segment. The included angle between the long arm segment and the short arm segments is 60°-80°. The guide trajectories defined by the long arm segment and the short arm segments together constitute the spatial guide path for the Z-shaped osteotomy. The pair of alignment channels are centrally symmetrically arranged with respect to the longitudinal center of the long arm segment, and the axis of the alignment channels is perpendicular to the bone surface of the first metatarsal. The above device enables precise three-dimensional spatial control of the osteotomy position, angle, and direction, reducing reliance on the surgeon's personal experience, standardizing the results of complex orthopedic surgeries, and completing the Z-shaped osteotomy in one operation through the spatial guide path. This reduces the operation time, shortens the high-temperature friction time between the guide blade and the bone, avoids the risk of thermal damage to local bone tissue, and facilitates postoperative recovery for the patient.

This invention discloses a novel catamaran amusement boat and buoyancy skateboard, comprising a hull 1 (buoyancy skateboard 1) and a hull 2 ​​(buoyancy skateboard 2) that are movably connected to both sides of the lateral end of a T-shaped fixing device. A rudder blade is movably connected to the outer side of the center of the lateral end of the T-shaped fixing device. The rudder stick and the rudder blade are connected to form a steering system. One end of a spring is fixed to the longitudinal long arm of the T-shaped fixing device, and the other end is connected to a spring pressure plate. Both ends of the spring pressure plate are connected to one end of two movable connecting rods, and the other ends of the two movable connecting rods are connected to the hull (buoyancy skateboard). When the hull (buoyancy skateboard) is opened outward, the movable connecting rod drives the spring pressure plate to compress the spring. When closed, the spring returns to its original position and discharges the water between the hull (buoyancy skateboard) to generate power. Continuous opening and closing can continuously generate power to propel the hull (buoyancy skateboard) forward, increasing the fun and movement of the water amusement.

To provide a support post for tethering quadrupedal animals that improves work efficiency when tethering quadrupedal animals. [Solution] The support post 1 for tethering quadruped animals comprises a long arm portion 65 and a support post body portion 20 that supports the arm portion 65. The support post body portion 20 comprises a column portion 51 that stands upright and an extension portion 52 that extends from the upper part of the column portion 51 in a direction intersecting the upright direction of the column portion 51. The end of the extension portion 52 and the end of the arm portion 65 are connected by a connecting portion 60, and in a plan view, the extension direction of the extension portion 52 and the length direction of the arm portion 65 are different. As a result, when a dog D is tethered, the column portion 51 is not located in front of the direction the dog D's face is facing, thus improving workability, such as trimming.
