Novel automatic telescopic pen

Abstract

The invention discloses a novel automatic telescopic pen. The novel automatic telescopic pen comprises a pen body and a cavity formed in the pen body. The end face of the left end of the pen body is provided with an open slot with a leftward opening. A first transmission shaft extending left and right is arranged in the cavity. The left end of the first transmission shaft is fixedly connected witha rotary rod extending out of the open slot. The tail end of the right end of the first transmission shaft is fixedly connected with a rotary disk. A first bevel gear located at the left end of the rotary disk is arranged on the first transmission shaft. The first bevel gear is in engagement connection with a power generation device. Clamping jaws are circumferentially and equidistantly distributed on the end face of the right end of the rotary disk. Sliding cavities provided with radial openings and circumferentially and equidistantly distributed are formed in the pen body. Springs are fixedly connected to the inner walls of the sliding cavities. The ends, close to the circle center of the pen body, of the springs are fixedly connected with lamping plates used for being connected with the corresponding clamping jaws in a sliding fit mode. The novel automatic telescopic pen is simple in structure, convenient to operate and capable of conducting multicolor switching and improving the convenience, changes the writing distance and prevents short-sightedness.

Description

technical field [0001] The invention relates to the technical field of stationery, in particular to an automatic new retractable pen. Background technique [0002] Pen is the most commonly used living device in life. Pens have undergone countless transformations and optimizations from ancient brushes to modern mechanized gel pens. The telescopic pens in the existing life are generally realized by the elastic change of the spring, the stability is not high, and it is easy to be damaged. And because the user's bad habits will cause the user's physical discomfort, it will cause irreversible damage such as myopia for a long time. Therefore, a new type of retractable pen has become an inevitable trend of development today, and the present invention illustrates a kind of retractable pen that can solve the above-mentioned problems. Contents of the invention [0003] The technical problem to be solved by the present invention is to provide a new automatic retractable pen, which...
