Double-button mechanism and pressing pen thereof

Abstract

The utility model provides a double-button mechanism and a pressing pen thereof. The double-button mechanism comprises a pressing cap installed on the top of the penholder and a hook installed on the side face of the penholder. The hook is provided with a finger-pressing part and a fixing part; the fixing part penetrates through a long sliding hole in the side surface of the penholder and is fixedly connected with the lower part of the press cap; the periphery of the pressing cap and the inner periphery of the upper end of the penholder are provided with matched clamping parts for preventing the pressing cap from sliding out from the upper part of the penholder; the hook fixing part is not contacted with the upper edge of the long sliding hole in the side surface of the penholder. The hook is linked with the press cap, the hook is also a press piece, the press cap or the hook can be pressed to drive the telescopic locking structure in the pen holder, and the hook and the telescopic locking structure form a double-button mechanism. The pressing pen adopts the double-button mechanism. According to the double-button mechanism, limiting is achieved and the pressing cap is prevented from falling off through the clamping and stopping part matched with the outer periphery of the pressing cap and the inner periphery of the upper end of the penholder, and the hook fixing part does not make contact with the upper edge of the long sliding hole in the side face of the penholder. Therefore, collision between the hook fixing part and the upper edge of the long sliding hole is avoided, and damage caused by eccentric force is avoided.
