The pneumatic clamp for grinding the valve element comprises a flange seat and an air cylinder arranged on the flange seat, a chuck assembly is arranged at the output end of the air cylinder, the chuck assembly comprises a connecting rod and a cylindrical elastic piece, one end of the connecting rod is fixedly connected with the output end of the air cylinder, the elastic piece is provided with a center hole for the connecting rod to penetrate through, and the connecting rod is arranged in the center hole. A first taper hole and a second taper hole which are communicated with the center hole are formed in the two end faces of the elastic piece respectively, the first taper hole, the center hole and the second taper hole form a sand clock structure together, a shaft hole allowing the output end of the air cylinder to penetrate is formed in the flange base, and a first taper block matched with the first taper hole is fixedly arranged on the flange base. A second conical block matched with the second conical hole is detachably arranged on the connecting rod, and when the air cylinder drives the second conical block to get close to the first conical block, the two ends of the elastic piece are pressed to deform outwards. The clamp can stably fix the valve element, operation is convenient and efficient, and the chuck assembly is convenient to replace.

The utility model discloses a rotary tray device of a plug seedling transplanter, which relates to the technical field of plug seedling transplanters and comprises a bottom frame and an adjusting unit. Mounting plates are arranged on the left side and the right side of the bottom frame, and a controller is fixed to the top end of the left side face of the bottom frame; the adjusting unit comprises a fixing shaft, a fixing plate, two linear motors, a motor and a fixing column, the two linear motors are fixed to the two sides of the interior of the bottom frame respectively, the inner side faces of rotor bases of the linear motors are connected with the end of the fixing plate, the motor is fixed to the bottom face of the fixing plate, and an output shaft of the motor is connected with the bottom end of the fixing shaft; according to the rotary tray device of the plug seedling transplanter, the height of the tray rack can be adjusted by adopting the linear motor, meanwhile, the motor drives the tray rack to rotate to facilitate personnel to take seedlings, and meanwhile, the distance between the tray racks can be adjusted by clamping the elastic convex blocks and the fixing holes, so that the carrying quantity of the seedlings can be increased, and the seedling transplanting efficiency is improved. And the seedlings can be prevented from being damaged by pressure.

This utility model discloses a cable positioning system for architectural design. A cable clamping positioning component is installed on one side of the fixing plate. Both ends of the fixing plate in the cable mounting groove are welded with clamping mounting posts. One end of the cable clamp has a first clamping hole corresponding to the clamping mounting post, and the other end has a second clamping hole corresponding to the clamping mounting post. A stud is threaded into the limiting screw hole. A splicing component is provided on one side of the fixing plate. The utility model involves placing the fixing plate in the installation position until the clamping mounting posts are fully embedded into the ends of the first and second clamping holes, completing the initial fixing operation. The stud is installed in the limiting screw hole. Turning the rotating handle causes the anti-slip pad to press the cable firmly, preventing it from slipping and falling off. If the cable position needs to be adjusted, the rotating handle is turned in the opposite direction to loosen the mounting stud. Fixing and loosening are convenient. To remove the cable, simply pull the cable clamp away from the clamping mounting post. Disassembly and adjustment are simple, facilitating subsequent replacement and maintenance.
