Description

Technical Field

[0001] The utility model relates to a pen, in particular to a lifting and pressing dual-operation automatic pencil. Background Art

[0002] A mechanical pencil with both a push-and-pull mechanism is a writing instrument that offers multiple operation modes, including both a push-pull mechanism and a push-pull mechanism. Most convenient pens on the market today offer either a push-pull or a push-pull mechanism. Comparing the two, push-pull mechanisms are less convenient than push-pull mechanisms, while push-pull mechanisms are less popular and offer a more limited operation, making them difficult to achieve both.

[0003] Therefore, we need a mechanical pencil that can take into account two operating modes at the same time, allowing people to choose their favorite operating mode at will. Utility Model Content

[0122] Supplementary Notes

[0123] 1. The eraser 6 can be replaced with other gadgets such as decorations, stamps, storage tools, etc.

[0124] 2. When using a rubber 6, the rubber 6 can also be used as a pressing object for the pressing operation. Through the conduction of the rubber 6, it acts on the transmission member 3 to press out the core. The specific method depends on the actual production situation. For example: In the first scheme, the rubber is retracted into the rear rod in the initial state. At this time, the core cannot be pressed out. The rubber has the function of pressing only after the rubber is rotated or pulled out. In the second scheme, the rubber exposes a part of the outer rod in the initial state, and the core can be pressed out. At this time, whether the rear rod has a rotation function or not does not affect the actual pressing effect. In the third scheme, the rubber can press out the core in the initial state. At this time, the rear rod can also be rotated to retract the rubber into the rear rod, thereby locking the effect of pressing out the core.

[0125] 3. In order to prevent the core from being ejected due to accidental pressing, the threaded connection between the transmission base 31 and the pressing piece 32 is a single-sided threaded connection. When the thread is fully tightened, the pressing piece 32 will form a limit with the end of the rear rod 2 or be retracted into the rear rod 2, playing a locking role to prevent the core from being ejected due to accidental pressing.

[0126] 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 size in the exposed state and / or the size in the retracted state, meets the actual usage requirements.

[0127] 5. When a pressing member is not provided, the transmission member partially protrudes from the rear rod. When a pressing member is provided, whether the transmission member protrudes from the rear rod is optional. When the pressing member or transmission member is not provided with an eraser, the initial state may be adjusted to partially protrude from the rear rod. If an eraser is provided, the eraser replaces the pressing member or transmission member, and the initial state may be adjusted to partially protrude from the rear rod. When a rotating member is provided on the rear rod, the rotating member replaces this part of the rear rod's function. The pressing member, transmission member, or eraser may be initially adjusted to partially protrude from the rotating member. In summary, the primary purpose of whether the rear rod is exposed is to provide space for the pressing operation.

[0128] 6. Operation method:

[0129] 1. Pulling operation: clamp the rear rod 2 with the tiger's mouth, clamp the front rod 1 with two fingers, and the two fingers and the tiger's mouth contract against each other, thereby causing displacement between the front rod and the rear rod to meet the lead-out trigger stroke, so that the lead can be discharged and collected normally.

[0130] 2. Pressing operation: On the premise of keeping the rubber, transmission part or pressing part exposed at a certain distance from the rear rod, keep the rear rod motionless and press the rubber, transmission part or pressing part to meet the lead discharge trigger stroke, so that the lead can be discharged and collected normally.
