Description

Technical Field

[0001] This invention relates to a pen, and more particularly to a pull-press dual-operation mechanical pencil. Background Technology

[0002] A pull-and-press dual-operation mechanical pencil is a writing instrument that offers multiple operation methods, including pulling and pressing to extend the lead. Most convenient pens on the market today offer either a press-and-press or pull-and-press design. Comparing the two, the press-and-press design is less convenient than the pull-and-press design, while the pull-and-press design is less common and offers limited functionality.

[0003] Therefore, we need a pull-and-press dual-operation mechanical pencil that can accommodate both operating methods, allowing people to choose their preferred method. Summary of the Invention

[0004] The purpose of this invention is to solve the problem that existing pencils have a single operation mode for lead extension and retraction, which cannot accommodate multiple operation modes, and to provide a dual-operation automatic pencil that combines lifting and pressing.

[0005] To achieve the above-mentioned objectives, the present invention adopts the following technical solution: A dual-operation mechanical pencil with lifting and pressing mechanism includes a lifting assembly, a transmission component, and an automatic lead module; the lifting assembly includes a front rod and a rear rod; the front rod and the rear rod are sleeved together to maintain at least the stroke for lifting out the lead; The transmission component is partially sleeved inside the rear rod, with the transmission component partially protruding from the rear rod, providing the stroke for pressing out the core; The front rod and the transmission component can be displaced relative to the rear rod, but they are not easily detached from the rear rod; The automatic lead core module is placed inside the lifting kit, and the transmission component is located at the non-writing end of the automatic lead core module and is detachably connected to the rear rod.

[0083] By rotating the rotating component 5, and through the cooperation of the rotation control protrusion 321 and the rotation control groove 51, the pressing component 32 can adjust the length of the ejected rubber 6. Example 5

[0084] like Figures 14 to 16 The illustrated pull-and-press dual-operation mechanical pencil includes a pull assembly, a transmission component 3, and an automatic lead module 4.

[0091] A limiting buckle 12 is provided on the side of the front rod 1 near the transmission component 3.

[0092] The aforementioned transmission component 3 is also provided with a core-loading hole 34, which facilitates the placement of the lead core.

[0093] A rubber 6 can be added to the transmission component 3, which is located away from the end of the front rod 1.

[0094] Supplementary Explanation 1. The eraser 6 mentioned above can be replaced with other small tools such as decorations, stamps, and storage tools.

[0095] 2. When using rubber 6, rubber 6 can also be used as the pressing object in the pressing operation. Through the transmission of rubber 6, the action is applied to the transmission component 3 to press out the core. The specific method depends on the actual production situation. For example: Option 1: In the initial state, the rubber is retracted into the rear rod, and the core cannot be pressed out at this time. Only after rotating or pulling out the rubber does it have the pressing function. Option 2: In the initial state, part of the rubber is exposed outside the rod, and the core can be pressed out. Whether the rear rod has a rotation function or not does not affect the actual pressing effect. Option 3: In the initial state, the rubber can press out the core. At this time, the rear rod can also be rotated to retract the rubber into the rear rod, thereby locking the pressing out effect.

[0096] 3. To prevent accidental pressing and ejection of the core, the threaded connection between the transmission base 31 and the pressing member 32 is a single-sided threaded connection. When the thread is fully tightened, the pressing member 32 will form a limit with the end of the rear rod 2 or be retracted into the rear rod 2, which plays a locking role to prevent accidental pressing and ejection of the core.

[0097] 4. Regarding the rubber part of the components of the present invention, it should be noted that, under normal circumstances, after adding the rubber, the length of the original pressing member 32 can be appropriately reduced or the length of the rear rod can be increased, so that the dimensional relationship between the rubber and the rear rod, including the dimensions in the exposed state and / or the dimensions in the retracted state, meets the actual use requirements.

[0098] 5. When there is no pressing component, the transmission component partially protrudes from the rear rod. When there is a pressing component, whether the transmission component protrudes from the rear rod is not a necessary condition. When the pressing component or transmission component is not equipped with a rubber eraser, its initial state may be adjustable to partially protrude from the rear rod. If a rubber eraser is provided, the rubber eraser replaces the pressing component or transmission component, and its initial state may also be adjustable to partially protrude from the rear rod. When a rotating component is provided on the rear rod, the rotating component replaces this function of the rear rod. The aforementioned pressing component, transmission component, or rubber eraser may initially be adjustable to partially protrude from the rotating component. In summary, the main purpose of whether the rear rod is protruding is to provide space for the pressing operation.

[0099] 6. Operating Instructions: 1. Lifting Operation: Clamp the rear rod 2 with your thumb and forefinger, and clamp the front rod 1 with two fingers. Contract your two fingers and the thumb and forefinger together to cause displacement between the front rod and the rear rod, which satisfies the lead ejection trigger stroke, and then the lead can be ejected and retrieved normally.

[0100] 2. Pressing Operation: While keeping the rubber, transmission component, or pressing component protruding a certain distance from the rear rod, keep the rear rod stationary and press the rubber, transmission component, or pressing component to meet the lead ejection trigger stroke, thus enabling normal lead ejection and lead retraction.
