The device comprises a creasing wheel arranged on a creasing wheel axle, wherein the creasing wheel axle is axially equipped with a row of rack-shaped clamping grooves; a first radial through hole and a second radial through hole are arranged on the inner wall of an axle hole of the creasing wheel; an axial through hole is arranged on the side face and is perpendicularly crossed with the first radial through hole and the second radial through hole; a tongue pressing block is inserted into the axial through hole; a bulge is arranged on the upper surface of the middle part of the tongue pressing block and props against the upper surface of the inner wall of the axial through hole; a latching block is inserted into the first radial through hole from top to bottom and is connected with the inner end of the tongue pressing block; a spring and a set screw are sequentially inserted into the first radial through hole from bottom to top; and a pressure pin is inserted into the second radial through hole and props against the lower surface of the outer end of the tongue pressing block. According to the invention, the latching block moves up and down through a lever mechanism formed by the tongue pressing block so that the latching block is meshed with or released from the clamping grooves; and therefore, the axial movement of the creasing wheel is convenient, and rapid self-locking localization of the creasing wheel can be realized.

The invention discloses an adjustable fracture reducer, which comprises a first guide rod, a second guide rod and a first half-ring fixing plate. One side of the first guide rod is movably connected with a first half-ring fixing plate. One side of the ring fixing plate is movably connected with a second guide rod, the top of the first guide rod is connected with a first semi-circular needle seat, the bottom side of the first guide rod is movably connected with a second half ring fixing plate, and the second The top of the half-ring fixing plate is fixedly connected with the second semi-annular needle seat, and there is a needle seat chute inside the second half-annular needle seat. The user can rotate the nut to loosen the connection between the needle holder and the needle seat chute, and manually Move the needle holder to a fixed position, so that the needle holder moves in the needle seat slide groove, which is convenient for adjusting the insertion position of the needle. The connecting plate is vertically arranged in the middle of the half-arc plate, which is convenient for the user to follow the position of the connecting plate. Adjusting the angle of the needle holder is suitable for the use of fracture reduction, and has broad development prospects in the future.

The invention provides a vertical cold isostatic press. The vertical cold isostatic press is characterized by comprising a high-pressure container and a seal end cover, wherein the high-pressure container is vertically arranged, and the top of the high-pressure container is open; the seal end cover is fixedly matched with the open end of the high-pressure container in a threaded manner, and the seal end cover comprises a threaded fixing seat and a seal seat which are arranged in a vertically split manner; the threaded fixing seat is fixedly matched with the high-pressure container in a threaded manner, and the seal seat is matched with the high-pressure container in a sealed manner; the threaded fixing seat can rotate independently relative to the seal seat, and an elastic mechanism is arranged between the threaded fixing seat and the seal seat; the elastic mechanism enables a certain separation gap to be formed between the threaded fixing seat and the seal seat, and the seal seat is connected to a connecting shaft penetrating through the center of the threaded fixing seat; and the connecting shaft is connected to a suspension mechanism enabling the seal end cover to be in a balance force state. By the adoption of the vertical cold isostatic press, on the basis of a horizontal type cold isostatic press, the situation that wear of a seal ring on the seal end cover is accelerated due to rotation is avoided, and meanwhile the vertical cold isostatic press is high in working stability, low in operation load, capable of being rapidly started and convenient to use.
