The technical problem to be solved by the embodiment of the application is to provide a novel telescopic pen so as to enable pen cores of different specifications to be used.

In order to solve the technical problems, the embodiment of the application provides a novel telescopic pen, which comprises a pen point, a pen cap, a pen core arranged in the pen cap, and a connecting rod arranged in the pen cap, wherein the pen point is arranged at the tail end of the pen cap, the pen point is rotatable, the tail end of the connecting rod is in threaded connection with the pen point, the front end of the connecting rod is connected with the tail part of the pen core, a rubber ring A is arranged on the connecting rod, and the rubber ring A is attached to the inner wall of the pen cap.

Further, the friction force between the rubber ring A and the inner wall of the pen cap is larger than the acting force between the pen point and the connecting rod along the rotation direction when the pen point rotates.

Further, the front end of the connecting rod is provided with a connecting part for being inserted into the pen core, and the connecting rod is connected with the tail part of the pen core through the connecting part.

Further, a rubber ring B is arranged on the pen point, and the rubber ring B is attached to the inner wall of the pen cap.

Further, the front end of the pen point is provided with a rotating part, and a limiting part corresponding to the rotating part is arranged in the pen cap.

Further, a limiting groove is formed in the connecting rod, and the rubber ring A is arranged in the limiting groove.

The beneficial effects of the application are as follows: according to the application, the pen cores with different thicknesses and lengths can be matched through the connecting rod, and the disassembly is convenient.

Detailed Description

It should be noted that, without conflict, the embodiments of the present application and features of the embodiments may be combined with each other, and the present application will be further described in detail with reference to the drawings and the specific embodiments.

In the embodiment of the present application, if there is a directional indication (such as up, down, left, right, front, and rear … …) only for explaining the relative positional relationship, movement condition, etc. between the components in a specific posture (as shown in the drawings), if the specific posture is changed, the directional indication is correspondingly changed.

In addition, the description of "first," "second," etc. in this disclosure is for descriptive purposes only and is not to be construed as indicating or implying a relative importance or implying an indication of the number of features being indicated. Thus, a feature defining "a first" or "a second" may explicitly or implicitly include at least one such feature.

Referring to fig. 1 to 6, the novel telescopic pen of the embodiment of the application comprises a pen point, a pen cap, a pen core and a connecting rod.

The pen refill is inserted from the tail of the pen cap and is arranged in the pen cap. The connecting rod is arranged in the pen cap.

The pen point is rotatably arranged at the tail end of the pen cap. The tail end of the connecting rod is connected with the pen point through threads. The front end of the connecting rod is connected with the tail part of the pen refill, the connecting rod is provided with a rubber ring A, and the rubber ring A is clung to the inner wall of the pen cap. Because the friction between the rubber ring A and the pen cap is large, the pen point can not drive the connecting rod to rotate when the pen point rotates, so that when a user rotates the pen point, the connecting rod moves back and forth in the pen cap, the connecting rod drives the pen core to stretch out and draw back, and the pen point at the front end of the pen core stretches out and retracts into the pen cap.

Preferably, the friction force between the rubber ring A and the inner wall of the pen cap is larger than the acting force between the pen point and the connecting rod along the rotation direction when the pen point rotates.

As one implementation mode, the front end of the connecting rod is provided with a connecting part for being inserted into the pen core, and the connecting rod is connected with the tail part of the pen core through the connecting part. Preferably, the front end of the connecting part adopts a pointed design, so that the pen refill can be inserted more conveniently. Because the connecting part is inserted into the refill hole for connection, the thick and long refill can be adapted.

As one implementation mode, the pen point is provided with a rubber ring B, and the rubber ring B is clung to the inner wall of the pen cap. The rubber ring B increases the acting force between the pen point and the pen cap, so that the pen point is tightly matched with the pen cap, and normal operation is not influenced.

As one implementation mode, the front end of the pen point is provided with a rotating part, and a limiting part corresponding to the rotating part is arranged in the pen cap. The limiting part is positioned at the rear side of the rotating part, and the rotating part is matched with the limiting part to prevent the pen point from falling off from the pen cap when rotating.

As one implementation mode, the connecting rod is provided with a limiting groove, and the rubber ring A is arranged in the limiting groove. The limiting groove is used for limiting the rubber ring A, so that the rubber ring A is prevented from shifting when the connecting rod is installed in the pen cap.

According to the structure for screwing the connecting rod and the pen point, the pen point can be freely telescopic through rotating the pen point.

Although embodiments of the present application have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made therein without departing from the spirit and scope of the application as defined by the appended claims and their equivalents.
