AI Technical Summary
Technical Problem
Makeup pen leads are prone to falling off or breaking when dropped or bumped, and cannot be fully retracted into the lead sleeve, affecting cleanliness and durability.
Method used
Design a cosmetic pen with a retractable lead. By setting a stop structure and a friction pusher inside the lead sleeve, and using a push rod to drive the lead sleeve and the lead to move back and forth synchronously, the lead can be flexibly extended and retracted. Combined with the protective function of the lead sleeve, it avoids direct impact.
Benefits of technology
It effectively prevents the pen tip from being damaged in case of accidental drops, improves the pen tip's drop resistance and lifespan, and meets the length adjustment needs of different makeup applications.

Abstract
The application discloses a cosmetic pen with a retractable refill, which comprises a pen body with a refill cavity, a refill arranged in the pen body, a refill sleeve, a push rod and a pushing mechanism, wherein the pushing mechanism is used for driving the push rod to drive the refill sleeve and the refill to move forward or backward; the cosmetic pen further comprises a first stop structure and a second stop structure. Thus, after use, the pushing mechanism drives the push rod to move backward, and drives the refill and the refill sleeve to move backward and retract into the pen body; when the refill sleeve moves to the second stop structure, the second stop structure limits the refill sleeve, prevents the refill sleeve from continuously moving backward, and the push rod continuously moving backward can drive the refill to completely retract into the refill sleeve; the refill retracts into the refill sleeve, the length of the exposed refill can be flexibly adjusted, the refill can be completely wrapped by the refill sleeve, the impact force can be effectively buffered when the cosmetic pen accidentally falls, and the fragile refill can be prevented from being directly impacted and damaged.
