This utility model relates to an engineering plastic positioning tool holder and anti-rotation tool holder system. The engineering plastic positioning tool holder includes a fiber-reinforced engineering plastic body and a cylindrical clamping cavity disposed therein. The inner wall of the clamping cavity is provided with two axially symmetrical protruding keys about a central axis. The axially symmetrical protruding keys and the body are integrally molded into an inseparable structure by injection molding, and their outer surface contours complement and match the contours of standard tool holder keyways. This utility model's engineering plastic positioning tool holder and anti-rotation tool holder system innovatively integrates the advantages of zero-backlash positioning, low-cost manufacturing, long service life, and lightweight design through an integrated protruding key structure. It effectively eliminates the circumferential rotational freedom of the tool holder while reducing manufacturing costs, providing a better solution for precision machining.

The invention provides a dust cover of a power transmission device for a vehicle, which can sufficiently ensure a labyrinth seal structure formed by the dust cover even when one end of a power transmission shaft is connected with another rotating body through a joint of an embedded structure, so as to suitably prevent foreign matters from entering the dust cover. The dust cover is of a split structure, so that the dust cover can be fixed to the gearbox after the power transmission shaft is assembled. Therefore, a labyrinth seal structure formed by the dust cover can be sufficiently ensured without fixing the dust cover at a position in order to avoid interference with a gear box which accommodates a bearing and an oil seal arranged at the other end of the power transmission shaft, so that intrusion of foreign matters can be appropriately inhibited.

[Use of the Article] This article is a holder for accurately positioning and temporarily securing gaskets used in ICF (ConFlat) flanges. [Function of the Article] This article is attached to the outer periphery of an ICF flange and holds the gasket in place, preventing it from falling or shifting, and facilitating and ensuring assembly. This allows for proper temporary securing of the gasket even when the flange surface is vertical. [Explanation of Configuration, etc.] This article has a roughly annular or partially divided structure and is designed to be detachably attached to the outer periphery of an ICF flange. The holder body has a support portion for holding the outer periphery of the gasket and is equipped with an elastic member or mechanical engagement means (e.g., a spring structure or clamp portion) for tightly fitting and engaging with the outer periphery of the flange. This configuration allows the gasket to be stably positioned between flanges even if the flanges do not have leak-check grooves, contributing to ensuring high airtightness in vacuum equipment. [Typical Usage] By attaching this article to the outer periphery of the flanges before inserting the gasket, the gasket is held in place. When the flanges are joined and fastened together in this state, the gasket undergoes plastic deformation, achieving an airtight joint. After the gasket is assembled, the item can be removed and reused. [Item description] The claws of this item are inserted between the flange bolts, so the claw width and shape are restricted by the bolt spacing, and it is inevitable that they will have a somewhat limited shape.
