[Embodiment of the invention]

 The present invention will be described with reference to the drawings. In FIG. 1, a screwdriver selection shaft 1 is formed in, for example, a hexagonal prism shape, and a plus (+) blade is formed at one end in the longitudinal direction. A negative screwdriver shaft 3 having a screwdriver shaft 2 formed and a minus (-) blade shape formed on the other end side is formed on a straight line in the longitudinal direction of the screwdriver selection shaft 1. The gripping shaft 4 has a concave groove 5 for preventing slippage in the outer peripheral portion in the longitudinal direction, and has one end formed to have a slightly smaller diameter to form a distal end surface 6, and has a hexagonal prism shape inward from the distal end surface 6. A nut fitting hole 7 into which the hollow eyeglass nut is fitted is formed at the center of the distal end face 6. The screwdriver shaft insertion hole 8 is formed in the longitudinal direction at the center of the gripping shaft 4 in a cylindrical shape further inside the nut fitting hole 7. More specifically, the screwdriver shaft insertion hole 8 is formed in a cylindrical cavity having a hole diameter into which the plus screwdriver shaft 2 and the minus screwdriver shaft 3 can be loosely fitted, and the length is a plus screwdriver shaft. It is desirable to form it into a length of about 1/2 of 2.

The screwdriver selection shaft fitting hole 9 communicates with the screwdriver shaft insertion hole 8, and is formed in a hexagonal column shape further inside. More specifically, the screwdriver selection shaft fitting hole 9 is formed by piercing a hexagonal column-shaped cavity large enough to fit the screwdriver selection shaft 1. The female screw 10 is bored inward from one end face of the grip shaft 4 opposite to the end face 6. One end of the restraining shaft loose fitting hole 11 communicates with the inner end of the screwdriver selecting shaft fitting hole 9, and the other end communicates with the inner end of the female screw 10, and the inside of the screwdriver selecting shaft 1. Drill at the center of the diameter direction in a cylindrical shape in the longitudinal direction. The restraining shaft 12 is formed in a cylindrical shape having an outer diameter of a different diameter. More specifically, the narrow diameter side is formed so as to have a diameter capable of loosely fitting into the screwdriver selecting shaft fitting hole 9, It is desirable that the large diameter side is formed to have a diameter that can be loosely fitted into the restraining shaft loose fitting hole 11, and the entire length of the restraining shaft 12 is formed to be approximately 5 mm longer than the plus screwdriver shaft 2. . The screwdriver shaft loose fitting hole 14 is bored in the center of the restraining shaft 12 in the diametric direction in the longitudinal direction. More specifically, the inside diameter of the screwdriver shaft loose fitting hole 14 is formed in a column shape into which the plus screwdriver shaft 2 or the minus screwdriver shaft 3 can be loosely fitted.

The cover cylinder 15 is provided with a male screw 16 screwed into the female screw 10 at one end thereof, and is screwed longitudinally inward from the center of the male screw 16 in the diametrical direction to form a shaft storage hole 17. Is drilled in a cylindrical shape. More specifically, the inside diameter of the screwdriver shaft storage hole 17 is formed to a size that allows the screwdriver shaft 2 or the screwdriver shaft 3 to be loosely fitted. The speeder 18 is rotatably attached to a shaft 19 that is inserted into the end face of the lid tube 15 opposite to the male screw 16.
