THE BIT SOCKET FOR AUTO-DRIVER

摘要

PURPOSE: A bit socket for an electric driver is provided to be fixed to the electric driver with a different front part such that nuts with different diameters are coupled. CONSTITUTION: A bit socket for an electric driver(70) comprises a socket body(10), upper and lower gears, a diameter-adjusting variable band(20),a tip, and a connecting bar(40). The socket body comprises guide rails and a projection shaft(15). The upper and lower gears are embedded in the guide rails formed on front and rear inner walls. The upper and lower gears are fitted into the projection shaft. The upper and lower gears guide a nut(60) to a long bolt(50) with being settled to the guide rail and projection shaft. The diameter-adjusting variable band is fixed to the front periphery of the electric driver, and fixes the socket body to the leading end of the electric driver. One end of the tip is mounted on a bit mounting unit, and the other end is connected to the center of the lower gear. The tip rotates the lower gear by the electric driver. One end of the connecting bar is connected to the diameter-adjusting variable band, and the other end is connected to the socket body.
