A tool holder of a machine tool, wherein a holder rear end part is fixed to the front end part of the spindle of the machine tool, a tool receiving surface part (8d) for receiving the rear end face of a shaft-like tool (11) fixed to a holder front end part so that a closed space (12) in contact with the rear end face can be formed and fog cutting fluid passages (8f, 9c) for leading fog cutting fluid fed from the front end part of the spindle to the closed space (12) are formed in a holder body (7) on a rotating center (R), and exhaust passages (8k, 8m, 8e) are formed for opening a part of the tool receiving surface part (8d) in contact with the closed space (12) to the atmosphere, whereby even when the shaft-like tool (11) is small in diameter and the amount of the fog cutting fluid flowing out to the atmosphere through a passage hole (11a) in the shaft-like tool (11) is small, the liquefied cutting fluid can be prevented from being accumulated in the fog cutting fluid passages (8f, 9c) by maintaining the flow velocity of the fog cutting fluid in the fog cutting fluid passages (8f, 9c) at proper levels.

The invention provides a multifunctional computer accessory machining device. The multifunctional computer accessory machining device comprises a rack, supporting legs, magnet blocks, impurity collecting boxes, supporting columns, a cross beam, a concentric-square-shaped sliding block, a telescopic push rod, a drilling motor, a drill bit and a deep groove ball bearing; the supporting legs are connected to the four corners of the bottom of the rack through bolts; the magnet blocks are connected to the upper middle portions of the inner sides of the supporting legs through bolts; and the impurity collecting boxes are arranged on the inner sides between the magnet blocks in an attracted manner. According to the multifunctional computer accessory machining device, by means of the arrangement of the stand columns, a fixing base, a clamping rod, a pull ring, a compressed spring and an anti-damage pressing base, various accessories can be better pressed and clamped, and drilling operation is facilitated; after the accessories are in place, the anti-damage pressing base can be used for conducting pressing and clamping operation, the pull ring is held by hand to pull the clamping rod, the anti-damage pressing base is lifted, and the accessories can be taken and placed; and the pull ring is loosened, due to the fact that the compressed spring releases energy, the anti-damage pressing base can rebound, the accessories are pressed, then drilling operation can be conducted, and operation stability is guaranteed.
