A retractable pen includes an improved triggering device (i.e., an actuating means), which is easy for manufacturing and user-friendly. The retractable pen has a pen-body having two pen-tubes, a pen-cartridge within the pen-body, and an actuating means. The actuating means not only triggers the movement of pen-cartridge (slidable protrusion / retraction of the pen-cartridge) but also, at the meantime, triggers length-change of pen-body (slidable movement between the two pen-tubes).

The invention provides an anti-drop pen. The pen holder is provided with a four-shuttle pen cap. Through the four-shuttle pen cap, when using the pen to insert the pen cap at the end of the pen holder, or when retracting and releasing the pen and putting the pen cap on the nib, the It can prevent the pen from slipping and breaking, it is beneficial to protect the pen tip, and it can also beautify the pen.

A retractable pen includes a barrel, an ink cartridge, a limiting member, a shifting member and a deformable member. When the shifting member is moved relative to the limiting member between a first position and a third position, the ink cartridge can be moved from a retracted position to an extended position or from the extended position to the retracted position. When the ink cartridge is located at the extended position, the deformable member can be further compressed by between the shifting member and the ink cartridge, allowing the shifting member to be moved further from the third position to a second position closer to the ink cartridge. When the shifting member is located at the second position, the ink cartridge is continuously held to the extended position and pressed against a lead-out opening of the barrel without the risk of swaying when a user writes with the retractable pen.

The invention discloses a scanning pen and a scanning pen device. The scanning pen comprises a pen body and a pen point structure arranged at one end of the pen body. The pen point structure is provided with a lighting element and a camera shooting element. A telescopic pen point used for making contact with a to-be-scanned object is arranged at the end of the pen point structure in a penetratingmode. A trigger switch is arranged in the scanning pen and used for controlling on-off of the lighting element and the camera shooting element. When the telescopic pen point is pressed to retract to make contact with the trigger switch, the lighting element and the camera shooting element are turned on, so that the lighting element illuminates a scanned object, and the camera shooting element shoots the scanned object. The pen point structure is arranged at one end of the pen body in a protruding mode, the camera shooting element and the lighting element of the pen point structure are not shielded by the pen body, there is no shielding object in the camera, the scanning range is increased, the size of the scanning pen is reduced, and the problem that an existing scanning pen is limited inscanning range can be at least partially solved.

The invention discloses a curve plotter, comprising a penholder, the left end of the penholder is provided with a nib, the right end of the penholder is provided with a back cover, the penholder is provided with a pen core storage cavity, and the pen core storage cavity is provided with Pressing mechanism, the pen core storage cavity is fixedly connected with a fixed plate extending up and down, and the middle part of the fixed plate is provided with guide sliding holes extending left and right; the invention is simple in structure, easy to use, and the equipment is equipped with a telescopic pen core, which is effective It is equipped with a rotating drive mechanism and a rotating extrusion mechanism to effectively control the entry and exit of the pen core. It is equipped with a non-slip rubber pad to improve the user's hand experience. In addition, it is also equipped with a cutting mechanism. When you need to use scissors and other equipment, you can directly use the pen's own cutting mechanism to cut, and when cutting, you only need to squeeze it, which is convenient and labor-saving.

The invention provides a retractable pen for being accommodated in a portable electronic device. The retractable pen includes a pen case, a pen shaft, a pen cap, a driving part and an elastic part. The pen shaft is fixed in the pen case and has a first ratchet structure. The pen cap has a second ratchet structure that is movably engaged with the first ratchet structure. The driving part is rotatably sleeved on the pen shaft and located in the pen cover. The driving part has a third ratchet structure. The elastic member is sheathed on the pen shaft and abuts between the pen shaft and the driving member. The elastic member constantly drives the driving member to move towards the first ratchet structure or the second ratchet structure. In the first state, the third ratchet structure abuts the first ratchet structure. In the second state, the third ratchet structure is movably engaged with the second ratchet structure and abuts against the first ratchet structure, and pushes the cap away from the pen case.
