摘要： A writing tool includes a writing unit, a capillary member, a dispensing unit, and a replaceable ink cartridge. The capillary member, the dispensing unit, and the replaceable ink cartridge are mounted in the writing unit. The dispensing unit contacts the capillary member and has at least one cutting portion. The replaceable ink cartridge accommodates ink therein and has a film at one end thereof. The replaceable ink cartridge can be installed in the dispensing unit and the film can be pierced and cut by the at least one cutting portion. The ink flows through the film and is delivered to the writing unit via the capillary member and the dispensing unit for writing. The writing tool can thus dispense the ink fluently and leave no residual ink.

摘要： A pressure regulating device for a writing tool has a deformable member. Minor air pressure variations in a pen tube of the writing tool can be regulated by deformation of the deformable member. Major air pressure variations in the pen tube can also be regulated by movement of the pressure regulating device. Thus, the pen tube of the writing tool can avoid internal air pressure imbalance caused by external high temperature or low air pressure. Before the writing tool is shipped from a manufacturer, the deformable member is pressurized in advance, such that the minor air pressure variation formed when a pen cap caps the writing tool offsets the air pressure pre-applied to the deformable member. Accordingly, ink inside an internal chamber does not spout out upon removal of the pen cap and the ink will not be overly dispensed or leak during writing.

摘要： A writing tool has a pen tube, a capillary unit, and a dispensing unit. The capillary unit is mounted in the pen tube, and is connected to a nib. The dispensing unit is mounted in the pen tube, and has a communicating tube and a pressing segment connected to the communicating tube. The pressing segment has at least one connecting arm connected to the communicating tube. A dispensing interval is formed between the communicating tube and a periphery of the pressing segment. The communicating tube contacts the capillary unit to make the capillary unit form different compression densities via the pressing segment and the dispensing interval, thus facilitating dispensing ink downward easily through the dispensing interval and providing a better occlusion effect to further avoid ink leakage.

摘要： An automatic cover-opening device has a body, at least one cover panel and a recoil mechanism. The body has an insertion hole defined in the body. The at least one cover panel is mounted on the body and moveably closes the insertion hole. Each one of the at least one cover panel has a guiding segment having at least one guiding edge inclined relative to an axis of the insertion hole to guide an axial force along the axis of the insertion hole to a lateral direction non-parallel with the axis, so as to generate a lateral component force for opening the at least one cover panel. The recoil mechanism is disposed on the body to push the at least one cover panel to a closed position for closing the insertion hole. With such an arrangement, an automatic cover-opening device that can be applied for insertion of a rod-like object is provided.

摘要： A lead frame has a metal base, a silver-plated layer, and a silver oxide layer. The silver-plated layer is formed between the metal base and the silver oxide layer. The silver oxide layer has a polar outer surface and a thickness of equal to or more than 1.3 nanometers. The silver oxide layer is beneficial to increase the adhesive strength between the lead frame and the molding compound and avoid delamination of the molding compound from the lead frame, so the lead frame of the present invention can pass a more severe moisture sensitivity level when exposed to the environment.

摘要： A multi-inclined anvil structure for a stapler has a body, an operating portion and a flattening surface. The body has a horizontal imaginary plane. The operating portion is recessed downward in the top of the body and has a projection plane that has a narrow front and a wide rear. The flattening surface is formed in a bottom surface of the operating portion and has two inclined bottom portions. Each inclined bottom portion is inclined and has a high front and a low rear relative to the horizontal imaginary plane. An inclined bottom angle is formed between an extension direction of the inclined bottom portions and the horizontal imaginary plane. When the stapler is applied to staple a few sheets of paper, a staple-sliding problem can be resolved. When the stapler is applied to staple many sheets of paper, a well-clinched quality can be provided.
