Referring to fig. 2 to 4, a first step portion 111 and a second step portion 112 are spaced apart from each other on a circumferential inner side wall of one end of the barrel body 11 close to the cap 13, and are used for being engaged with the cap 13 to assemble the cap 13 to the barrel body 11, and a specific assembly structure thereof will be described in detail later. An opening 113 is formed on the circumferential outer side wall of the cartridge body 11 at a position corresponding to the button 12. The end of the pen holder body 11 far away from the pen cap 13 is provided with an external thread part 114.

The button 12 is a U-shaped groove structure and includes a first inner side plate 121 and two second outer side plates 122 respectively disposed at two sides of the first inner side plate 121. At least two buckles 123 are convexly arranged at an interval at one end of the outer side of the second outer side plate 122 far away from the first inner side plate 121. At least two first oblique driving portions 124 are protruded from the inner side of the second outer plate 122 for cooperating with the lead driving assembly 20, and the assembly structure thereof will be described in detail later.

In this embodiment, the number of the latches 123 is four, and the four latches 123 are respectively disposed on two sides of the second exterior plate 122. The four buckles 123 are respectively clamped in the opening 113, so that the button 12 can be assembled on the circumferential outer side wall of the pen holder body 11.

The cap 13 includes a cap body 131, a clip 132 disposed on the circumferential outer sidewall of the cap body 131, a rubber cap 133 disposed on an end of the cap body 131 remote from the barrel body 11, and an eraser 134 disposed between the cap body 131 and the rubber cap 133.

The rubber 134 is partially positioned inside the cap body 131, and the rest part is covered by the rubber cap 133. When the user wants to use the eraser 134 for correction, the eraser cap 133 can be pulled off, so that the eraser 134 can be used. When not in use, the user can cover the rubber cover 133 to protect the rubber 134 from being lost.

The lead core transmission assembly 20 includes a core tube 21, a core rod 22 disposed at an end of the core tube 21 close to the nib assembly 30, and a core cap 23 disposed at an end of the core rod 22 away from the core tube 21.

At least two second oblique driving portions 211 are arranged on the circumferential outer side wall of the core tube 21 at intervals. The second oblique driving portion 211 has the same inclination angle as the first oblique driving portion 124 and is in abutting engagement with each other. When the button 12 is pressed, the button 12 moves toward the core tube direction, and the button 12 is not changed in a direction perpendicular to the axial direction of the core tube 21, so that the core tube 21 moves toward the core rod 22 by the cooperation of the first oblique driving portion 124 and the second oblique driving portion 211.

A third step part 212 is arranged on the circumferential inner side wall of one end of the core tube 21 close to the pen point assembly 20.

The core rod 22 includes a core rod body 221, a circular table portion 222 disposed at one end of the core rod body 221 near the core tube 21, a core rod clamp 223 disposed at the other end of the core rod body 221, and a spring 224 disposed around the outside of the core rod body 221.

The circular table portion 222 is interference-fitted with the third step portion 212, so that the core rod 22 can be assembled to the core tube 21. One end of the spring 224 near the circular table 222 abuts against the end surface of the barrel 21 near the nib assembly 30.

The end of the core cap 23 away from the core tube 22 is provided with a brim 231. The maximum bore diameter of the core cap 23 is smaller than the minimum axial diameter of the bottom surface of the mandrel holder 223. The core cap 23 is sleeved on the core bar chuck 223.

An inner thread part 31 is arranged on the circumferential inner side wall of one end of the pen point component 30 close to the pen holder component 10. The inner thread part 31 is matched with the outer thread part 114, so that the pen point component 30 can be assembled on the pen holder component 10. The bottom of the internal thread part 31 is convexly provided with a fourth step part 32. The cap brim 231 is fixedly interposed between the fourth stepped portion 32 and the bottom surface of the cartridge body 11.

A detailed description will be given below of how to use the side-push type mechanical pencil provided by the present invention. The two second oblique driving portions 211 are matched with the four first oblique driving portions 124. Pressing the button 12 causes the barrel 21 to move the stem 22 toward the nib assembly 30, and the spring 224 is compressed. Releasing the button 12, the spring 224 rebounds. Such repeated pressing of the button 12 causes the plunger 22 to reciprocate in the longitudinal direction thereof.

The cartridge cap 23 is fixed between the fourth stepped portion 32 and the bottom surface of the cartridge body 11. The core rod collet 223 reciprocates within the core cap 23. When the button 12 is depressed, the mandrel holder 223 is in an open state, and when the button 12 is released, the mandrel holder 223 is in a closed state.

The core rod gripper 223 grips the pencil core in the closed state and moves in the direction of the nib assembly 30. The plunger rod gripper 223 is moved to an initial position in an open state and returned to a closed state, so that the pencil leads are fed out of the nib assembly 30 by reciprocating motion.

Compared with the prior art, the side-push type mechanical pencil provided by the utility model has the advantages that the button 12 is arranged on the side wall of the pencil holder main body 11, the first inclined driving part 124 is arranged on the button 12, the second inclined driving part 211 is arranged on the core tube 21, and through the matching and mutual driving between the first inclined driving part 124 and the second inclined driving part 211 arranged on the core tube 21, when the button 12 is repeatedly pressed, the core rod 22 can reciprocate in the length direction, so that the purpose of feeding the core is achieved, and the using state of the rubber 134 at the pen cap 13 is not influenced. Meanwhile, when the side-push type mechanical pencil is used, when the button 12 needs to be pressed, the posture of a hand holding the pencil does not need to be changed, and the other hand does not need to be used for pressing the button 12, so that the side-push type mechanical pencil is convenient and quick to use.
