The utility model discloses a plastic forming machine positioning mechanism which comprises a workbench, two ends of the upper surface of the workbench are symmetrically and fixedly connected with racks, the opposite sides of the two racks are both provided with blanking guide assemblies, the inner sides of the two blanking guide assemblies are both fixedly connected with connecting rods, and the connecting rods are fixedly connected with two ends of the workbench. The opposite sides of the two connecting rods are jointly and fixedly connected with a discharging hopper, a collecting box is placed in the center of the upper surface of the workbench, and a positioning assembly matched with the collecting box is installed on the upper surface of the workbench. According to the blanking device, by means of the blanking guide assembly, products formed and falling between the male die and the female die can fall into the blanking hopper and then fall into the collecting box, meanwhile, the cam rotates to periodically push the abutting and pushing plate in a reciprocating mode, so that the blanking hopper shakes back and forth in a small range, the products cannot be clamped on the inner wall of the blanking hopper, and the production efficiency is improved. And the water can also uniformly fall into all positions of the collecting box, so that the device is relatively practical.

The invention discloses a correction device for developmental dysplasia of the hip in children; the device comprises a first inverted V-shaped wrist support suitable for supporting the left knee wrist of a child, a second inverted V-shaped wrist support suitable for supporting the right knee wrist of a child, and a telescopic adjustment member used for adjusting the distance between the first inverted V-shaped wrist support and the second inverted V-shaped wrist support so as to spread the left thigh and the right thigh of the child; the effect is that the legs of the child can be spread to the abduction position and fixed, which is beneficial to the correction treatment of the developmental dysplasia of the hip, the thighs of the child are only supported by the first inverted V-shaped wrist support and the second inverted V-shaped wrist support, so that the use is comfortable, and the telescopic adjustment member itself has an adjustable telescopic length, so that the distance between the first inverted V-shaped wrist support and the second inverted V-shaped wrist support is adjustable, so that the distance between the first inverted V-shaped wrist support and the second inverted V-shaped wrist support can be adjusted to a suitable distance for use according to the size of the lower body of the child, and thus the invention has a good use effect.

The utility model discloses an aluminum flux-cored wire processing device for multi-welding-wire linear adjustment, and particularly relates to the technical field of welding wire processing, the aluminum flux-cored wire processing device comprises a sliding frame, the upper surface of the sliding frame is fixedly connected with two positioning adjusting sleeve plates, and the inner walls of the positioning adjusting sleeve plates are provided with multi-point-position adjustable assemblies; the multi-point-position adjustable assembly comprises two guide columns fixedly arranged on the inner walls of the positioning adjusting sleeve plates, a supporting block is fixedly connected to the position, located between the two positioning adjusting sleeve plates, of the upper surface of the sliding frame, and two electric cylinders are fixedly installed at the top end of the supporting block.
