Abstract

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.

Abstract

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.

Abstract

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.

Abstract

A reciprocating pencil sharpener has a shavings receptacle, a stationary member, a cutter and a ratchet mechanism. The cutter includes a blade secured to a blade holder. The ratchet mechanism is mounted between the stationary member and the cutter and allows the cutter to rotate relative to the stationary member in one direction only. When a user desires to sharpen a pencil, the user can keep the pencil in the hand and rotate the pencil in reciprocating rotation, thus obtaining the sharpened point of the pencil. Consequently, it is convenient for the user to apply a rotational force and a high efficiency of sharpening operation is achieved.

Abstract

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.

The automatic locking device is mounted on the slider and has a resilient member selectively engaging at least one of the engaging teeth. The screw locking device is mounted on the slider and has a relative travel distance between the screw locking device and the slider. The blade is mounted slidably in the blade holder and connected to the slider.

Abstract

A flat-clinch stapler has a base, a magazine assembly, a handle device, a flat-clinch device and a buffering device. The magazine assembly and the handle device are pivotally connected with the base. The flat-clinch device has a slider and a moving board. The slider is slidably mounted on the base. The moving board is mounted above the slider and is pivotally connected with the base. The buffering device has a protrusion, a block and an elastic member. The protrusion is securely disposed on the moving board. The block is slidably mounted on the base and abuts the protrusion. The elastic member abuts the block and the base. When the moving board is pivoted, the block is driven by the protrusion to move.

Abstract

A pencil sharpener has a waste case, a blade base, a blocking chunk, a blade, a rotating knob and an adjusting shaft. The waste case has a mounting hole and multiple positioning segments formed on the inner wall of the mounting hole. The blocking chunk is moveably mounted on the bottom of the blade base along an axial direction of the blade base. The blade is mounted securely on the blade base. The rotating knob is mounted rotatably in the mounting hole in the waste case and has at least one engaging segment selectively engaging the positioning segments of the waste case. The adjusting shaft is connected securely with the rotating knob and is disposed on the blocking chunk. When the rotating knob is rotated, the adjusting shaft is rotated to push the blocking chunk to move along the axial direction of the blade base.

Abstract

A slider has an upper sliding element, a lower sliding element and a resilient tab. The upper sliding element has two first engaging segments disposed on an inner side of the upper sliding element. The lower sliding element has two second engaging segments disposed on an outer side facing the inner side of the upper sliding element and engaging the first engaging segments. A tab holding base is formed on and protrudes from the outer side of the lower sliding element and has a chamber defined in the tab holding base. The resilient tab is held in the chamber in the lower sliding element and has two legs. Accordingly, a slider having a structure in a closed condition is provided to prevent objects from entering into the chamber to interfere the operation of the resilient tab and the operation of the slider is smooth.

Abstract

A stapler has a center of gravity and has a base assembly, a magazine assembly and a trigger assembly. The magazine assembly connects to the base assembly and has a cap. The trigger assembly connects to the base assembly and has a trigger lever and a limiting lever. The limiting lever prevents the trigger lever and the cap from pivoting excessively to keep the center of gravity of the stapler over the base assembly so that refilling the stapler is convenient.
