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.

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 telescopic safety pen. The telescopic safety pen comprises a pen point, a pen body and a pen cap, wherein the pen body is further provided with a telescopic rod; one end of the telescopic rod is provided with external screw threads; the pen point is provided with internal screw threads; the pen point is in threaded connection with one end of the telescopic rod, while a groove is formed in the other end of the telescopic rod; the groove is an arc rectangular groove; concave cavities are symmetrically arranged in the groove; positioning spring beads are arranged in the concave cavities; concave holes are formed in the end of the telescopic rod; clamping spring beads are arranged in the concave holes; the concave holes and the concave cavities are arranged at the same end of the telescopic rod; clamping V-shaped ring grooves are symmetrically formed in the inner wall of one end of the pen body, while positioning convex blocks are symmetrically arranged on the inner wall at the other end of pen body; positioning holes are formed in the positioning convex blocks.
