Description

Electric ballpoint pen with refill protection

technical field

The utility model relates to a ball-point pen, in particular to an electric ball-point pen for protecting the core.

Background technique

At present, there are two types of ballpoint pens available in the market according to the retractable refills, one with retractable refills and the other with non-retractable refills. The non-retractable ball-point pen tip of the pen core is exposed outside the pen tube, and the ball-point pen tip is easily damaged and cannot be used. When important things such as examinations and signing contracts need to use the pen and there is no spare pen, it will delay things. Existing retractable ball-point pens with refills are all artificially pressed, which is acceptable for normal people, but it is more laborious and inconvenient for handicapped people, the elderly, and young children to use.

Contents of the invention

The purpose of the utility model is to provide an electric ballpoint pen with a pen core that can be automatically retracted by electric power to protect the pen core.

The technical solution adopted by the utility model is that the electric ballpoint pen for protecting the refill, the refill is inserted in the pen tube, the nib of the refill is placed at the pen hole at the front end of the pen tube, and the tail end of the refill is sleeved on the pen tube. In the fixed frame, the fixed frame is connected with the front end of the telescopic rod, the middle end of the telescopic rod is connected with the runner on the rotating shaft of the miniature reversible motor, the miniature reversible motor is connected with the battery, and a limit plate is set at the end of the telescopic rod , on the inner wall of the pen tube, a telescopic rod touch switch is set before and after the fixed frame, a forward and reverse switch is set on the outer wall of the pen tube, and a spring is set on the middle shaft of the forward and reverse switch. The motor is connected.

Due to the adoption of the above technical scheme, the utility model has the following advantages: when the pen core is retracted into the pen tube, press and hold the front end of the forward and reverse switch, the miniature forward and reverse motor starts to rotate, and the miniature forward and reverse motor rotates on the shaft. The rotating wheel rotates accordingly, and then drives the telescopic rod to extend forward, the telescopic rod drives the fixed frame to extend forward, the fixed frame drives the pen core to extend forward, the fixed frame touches the touch switch on the front end, the power is turned off, and the miniature forward and reverse motor stops working , the tip of the pen is exposed from the barrel, and you can use it for writing. After use, release the hand holding the front end of the forward and reverse switch. Under the action of the spring, the front end of the forward and reverse switch is lifted up, the rear end is lowered and the reverse circuit is connected, the miniature forward and reverse motor starts to reverse, and the miniature forward and reverse motor The rotating wheel on the rotating shaft reverses accordingly, and then drives the telescopic rod to retract, the telescopic rod drives the fixed frame to retract, the fixed frame drives the pen core to retract, the fixed frame touches the touch switch at the rear end, the power is turned off, and the miniature forward and reverse The motor stops working, and the nib retracts into the pen tube to protect the nib. In short, press and hold the forward/reverse switch, the tip of the front end of the pen will protrude, release it, and the tip of the pen will automatically retract without worrying about the tip being exposed and damaged. It is easy and convenient to use.
