AI Technical Summary
Traditional push-button pens require multiple springs to be installed inside the pen barrel to achieve the rebound of the pen tip and the cap, which is complex in structure and does not have a decompression function.
A single spring is used to simultaneously achieve the rebound of the pen refill and the snap cap. Through the combination of a pull rod, push rod and locking component, combined with an external spring and elastic rubber ring, the structure is simplified and the decompression function is added.
The number of springs used was reduced, simplifying the structural design while increasing the product's aesthetics and decompression function, thus improving the user experience.

Abstract
Description
Technical Field
[0001] This utility model relates to pens, specifically to a press-type pen. Background Technology
[0002] Traditional push-button pens, due to structural design limitations, require at least one spring to be installed inside the pen barrel. The spring acts on the pen tip (pen tip spring) and / or the locking element / wheel of the telescopic locking mechanism (locking element / wheel spring) to achieve the return of the pen tip. If the return of the snap cap is required, a spring (snap cap spring) also needs to be installed on the snap cap. Utility Model Content
[0003] This invention proposes a press-type pen, which further improves the pen's structure by using a spring to simultaneously achieve the rebound of the pen core and the press cap.
[0004] The technical solution of this utility model: A push-button pen includes a pen barrel, a telescopic locking mechanism, a pen refill, a snap cap, and a snap cap spring. The telescopic locking mechanism is disposed within the pen barrel and consists of a push rod, a locking element, and a guide rail. The pen refill is disposed within the pen barrel, and the snap cap spring is mounted on the snap cap. The push-button pen also includes a pull rod and an elastic element. The pull rod is disposed within the pen barrel, passes through the locking element, and is rotatably connected to the locking element. The pull rod also passes through the push rod and is clearance-fitted with the push rod. One end of the pull rod is connected to the pen refill, and the other end is connected to the snap cap. A step is provided on the pull rod, which is located on the side of the locking element and supports the locking element. The elastic element is mounted on the push rod and applies an elastic force to the push rod. The push rod is in contact with the locking element.
[0005] Extended state: Pressing the snap cap once moves the lever, and the locking element, push rod, and pen refill move accordingly (pen refill extends). When the locking element disengages from the guide rail, (the elastic element applies elastic force to the push rod, and the push rod acts on the locking element) the locking element rotates; releasing the snap cap causes it to spring back, moving the lever, and the locking element, push rod, and pen refill move accordingly, with the locking element locking at the end of the guide rail; Retracted state: Press the snap cap again to move the lever, and the locking element, push rod, and pen refill move accordingly. The locking element is released. At this time, the locking element is not restricted, and the locking element (the elastic element applies elastic force to the push rod, and the push rod acts on the locking element) rotates again; release the snap cap, the snap cap springs back, and the lever moves, and the locking element, push rod, and pen refill move accordingly (the pen refill retracts), and the locking element enters the guide rail.
[0006] Further refining the above technical solution, the pen barrel has a step on its outer periphery; the spring is externally mounted, with one end of the spring resting on the step and the other end resting on the snap cap; the externally mounted spring, without affecting the pen's function, makes the pen more aesthetically pleasing.
[0007] Further refining the above technical solution, the spring is a one-piece molded plastic part; this lays the foundation for further enriching the functions of the spring in the future.
[0008] The above technical solution is further refined, including the shape of the spring.
[0009] To further refine the above technical solution, a pattern is printed on the spring.
[0010] Further refining the above technical solution, the elastic element is an elastic rubber ring, which is sleeved on the pull rod and clamped between the push rod and the snap cap.
[0011] Further refining the above technical solution, the pen barrel is composed of several pen barrel sections connected together.
[0012] The above technical solution is further refined, with each section of the pen barrel connected by threads.
[0013] Further refining the above technical solution, the spring is fitted with the pen barrel with a clearance, and the spring is in a relaxed state when the snap cap is not pressed once; thus, the spring can be easily rotated when flicked, serving as a stress-relieving toy.
[0014] Further refining the above technical solution, the pull rod is a round rod that passes through the central round hole of the locking component and leaves a gap between it and the central round hole of the locking component.
[0015] The advantages of this utility model are that it is reasonably designed and ingeniously conceived. Compared with the traditional press-type pen (with a snap-on cap), it saves at least one spring. It also maximizes the function of the spring, enhances the product's appearance design, and has a decompression function. Attached Figure Description
