Thus, a feature defining "a first" or "a second" may explicitly or implicitly include at least one such feature.

Referring to fig. 1 to 9, a pen with a replaceable pen core according to an embodiment of the present utility model includes a pen body and a pen core.

The pen body is provided with a pen refill cavity for containing a pen refill, the tail part of the pen refill cavity is provided with a pressing and ejecting mechanism, and the pressing and ejecting mechanism comprises a sleeve, a push rod, a sliding claw sleeve and a spring. The end of the pen core is connected with a push rod, the push rod is arranged in the sleeve, and the sliding claw is sleeved with the end of the push rod in an abutting fit manner under the action of the spring. The push-up mechanism is similar to the existing push-up ball-point pen in structure, and is different in that the refill of the existing ball-point pen is contacted with the sliding jaw under the action of the spring, the push rod is connected with the push tail cap, and the push rod is connected with the refill. The pen point of the pen core is exposed out of the pen body in a normal writing state, so that writing is convenient; when the pen core is required to be ejected, the pen core is pressed on the paper, the pen core is ejected, so that a user can conveniently pull out the pen core, and then the pen core is replaced or turned around (namely, the pen core is turned around, and the pen core is replaced by a rubber cap at the other end of the pen core, so that writing on a capacitive screen is more convenient); when reinstallation is performed, the pen refill is inserted into the pen refill cavity, and the tail end of the pen refill is connected with the push rod.

As one implementation mode, the inner wall of the sleeve is provided with n guide posts, n guide grooves are formed between the guide posts, n guide blocks matched with the guide grooves are arranged on the periphery of the push rod, n sliding blocks matched with the guide grooves are arranged on the periphery of the sliding claw sleeve, 2n convex teeth are arranged at the front end of the sliding claw sleeve, 2n convex teeth are sequentially arranged into a circle, n convex blocks corresponding to the convex teeth are arranged at the tail end of the push rod, the convex teeth are triangular, and the front ends of the convex blocks are inclined planes. In the concrete implementation, the convex teeth can also be arranged at the tail end of the push rod, and the convex blocks are arranged at the front end of the sliding claw sleeve. The tail end of the guide post and the front end of the sliding block are provided with corresponding matched inclined planes, the spring applies forward elastic force to the sliding jaw sleeve, n is an integer greater than or equal to 2, and n is generally 3 or 4. This part of the structure is similar to the structure of the existing push type ball point pen.

As an embodiment, the end of the sleeve is provided with an end cover, one end of the spring acts on the end cover, and the other end of the spring acts on the sliding claw sleeve. In practice, the sleeve may be provided on a main support in the pen body. The end cover seals the spring in the sleeve, so that the assembly is convenient, and the spring is prevented from falling off.

As one implementation mode, a control main board is arranged in the pen body, the pen refill is a ball-point pen refill or a neutral pen refill with a metal part, and a signal transmitting end of the control main board is communicated with the metal part of the pen refill. The metal part of the conventional ball-point pen refill or gel ink pen refill is a pen point, and if the ball-point pen refill or gel ink pen refill with a metal shell is adopted, the metal part is a metal shell.

As one implementation mode, the tail end of the pen core is provided with a rubber cap. The rubber cap is made of conductive silica gel, so that writing on the capacitive screen is facilitated, and the writing on the capacitive screen is realized by turning around the pen core and inserting the pen core into the pen core cavity; the pen point can be directly used for writing on the capacitive screen, and the pen point is metal and can be directly used for writing on the capacitive screen.

As an implementation mode, the front end of the push rod is provided with a slot corresponding to the tail end of the pen core, and the pen core is in interference connection with the slot of the push rod, so that the pen core is conveniently pulled out and reinserted into the slot.

As one implementation mode, a limiting part for preventing the push rod from being ejected out of the sleeve by the spring is arranged in the pen core cavity. The limiting part prevents the push rod from separating from the sleeve along with the pen core when the pen core is pulled down.

As one implementation mode, an action part for preventing the refill from shaking along with the push rod during writing is arranged in the refill cavity. The action part can adopt an elastic piece arranged on the side surface of the pen refill cavity, and the top of the elastic piece is contacted with the pen refill.

Although embodiments of the present utility model 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 utility model as defined by the appended claims and their equivalents.
