TECHNICAL FIELD
[0001] The patent relates to the technical field of writing tools, in particular to a pen with a core pulling function. BACKGROUND
[0002] The existing ballpoint pens or neutral pens on the market include a pen barrel and a pen core in the pen barrel, and the control of the pen core is realized through the setting of a top push button or a side push button. The push button of the ordinary push button ballpoint pen or neutral pen is set on the top end or side of the pen barrel, and needs to be directly used as a push button for finger pressing, or a sleeve called a push cap is sleeved on the push button, which is used as a push button for finger pressing, and the push cap is also located on the top end or side of the pen barrel, so that the top end of the pen barrel cannot be used for other purposes. If other functional parts, such as a touch head that can be used for touch input on an electronic touch screen or a rubber block that can erase ink traces, are arranged on the top end or side of the pen barrel, and the other functional parts are used as a push button for finger pressing, the push action will be not smooth and the hand feeling will be very poor due to the softness of the touch head and the rubber block, and the inner wall of the touch head needs to have a gap and the rubber block will be worn out during use. Moreover, the traditional top push button and side push button setting makes the use mode single and homogenized. With the increasing of the threshold of user's expectation for products, a pen that is different from the existing push button mode and can bring fresh use experience to users is needed. CONTENT OF THE UTILITY MODEL

The pen barrel is provided with the pressing and rotating mechanism and the core pushing mechanism at the upper end. One end of the core pushing mechanism abuts against the pressing and rotating mechanism, and the other end of the core pushing mechanism abuts against the pen core. When the pressing and rotating mechanism is forced to rotate, the core pushing mechanism moves from a first position to a second position, and the pen core is pushed out. When the pressing and rotating mechanism is forced to rotate back, the core pushing mechanism returns from the second position to the first position, and the pen core is retracted.
[0005] Further, the pressing and rotating mechanism comprises a rotating shaft and a guide block. The top end of the guide block comprises a first sliding part, and the bottom end of the guide block comprises a first limiting protrusion and a second sliding part.

[0045] The detailed features and advantages of the present patent are described in detail in the specific embodiments below, which are sufficient for any person skilled in the art to understand the technical content of the present patent and to implement it, and the person skilled in the art can easily understand the purposes and advantages related to the present patent according to the description, claims and drawings disclosed in the present specification.
[0046] In order to make the purposes, technical solutions and advantages of the present patent clearer, the embodiments of the present patent will be further described in detail below with reference to the drawings.
[0047] As shown in Figures 1-3 , a pen with a core-pushing function in a retracted state is shown, which includes a pen barrel 200, a pressing and rotating mechanism 300 and a pen neck 500. The pen barrel 200 is arranged at the upper part of the pen, and the pen neck 500 is arranged at the lower part of the pen. The pen barrel 200 and the pen neck 500 are hollow thin-walled cylindrical structures, and the interior of the pen barrel 200 and the pen neck 500 forms a cylindrical cavity after being connected. The upper end of the pen barrel 200 is provided with a rectangular open slot 210, and the pressing and rotating mechanism 300 is arranged at the same horizontal position as the open slot 210. Part of the pressing and rotating mechanism 300 protrudes radially from the cavity to the open slot 210, that is, the state of the pressing and rotating mechanism 300 can be adjusted, controlled and changed through the open slot 210.
[0048] As shown in Figure 4 and Figure 5 , the internal structure of the pen is further shown. The pen further includes a core-pushing mechanism 400 and a pen core 600. The cavity formed by the combination of the pen barrel 200 and the pen neck 500 is sequentially provided from top to bottom with a top plug 100, the pressing and rotating mechanism 300, the core-pushing mechanism 400, the pen core 600 and an elastic member 510. The top plug 100 is used to close the opening at the top end of the pen barrel 200. Part of the pressing and rotating mechanism 300 is arranged in the cavity, and the other part protrudes from the open slot 210. The pressing and rotating mechanism 300 abuts against the core-pushing mechanism 400, and the core-pushing mechanism 400 abuts against the pen core 600. The bottom end of the pen neck 500 is internally sleeved with the elastic member 510, and the inner diameter of the elastic member 510 is smaller than the inner diameter of the pen core 600. It is easy to understand that the force generated when the pressing and rotating mechanism 300 moves will be transmitted to the core-pushing mechanism 400, and the core-pushing mechanism 400 will push the pen core 600 out of the bottom end of the pen neck 500 under the action of force. The pen barrel 200 includes the open slot 210 and an inner wall limiting slot 220. The inner wall limiting slot 220 is arranged below the pressing and rotating mechanism 300 and is used to limit the displacement of the sliding block 420 in the axial direction. The top of the open slot 210 is provided with a first sliding groove 211 in the radial direction, and the first sliding groove 211 is an arc-shaped track, so that the pressing and rotating mechanism 300 can displace along the first sliding groove 211. The bottom of the open slot 210 is provided with a second limiting protrusion 212 at the outer end, and the second limiting protrusion 212 can cause the pressing and rotating mechanism 300 to displace fixedly.
[0049] The pressing rotating mechanism 300 comprises a rotating shaft 310 and a guide block 320. The rotating shaft 310 is fixed in the middle of the open slot 210. The guide block 320 is arranged on the rotating shaft 310. It is easily understood that the guide block 320 can rotate around the rotating shaft 310. The guide block 320 comprises a first sliding part 321, a first limiting protrusion 322 and a second sliding part 323. The guide block 320 has an arc-shaped pressing surface which is suitable for fingers. The top of the guide block 320 is provided with the first sliding part 321 which is an arc-shaped edge matching the first sliding slot 211. The bottom of the guide block 320 is provided with the second sliding part 323 which is an arc-shaped edge. The innermost end of the second sliding part 323 is provided with the first limiting protrusion 322. The second limiting protrusion 212 can make the guide block 320 fixedly slide in the rotating movement. It is easily understood that in the process of the rotating movement of the guide block 320, the first sliding part 321 slides on the first sliding slot 211, and the second sliding part 323 slides between the second limiting protrusion 212 and the third limiting protrusion 411. When the first limiting protrusion 322 slides to the second limiting protrusion 212 and abuts against each other, the first sliding part 321 is located in the cavity, and the second sliding part 323 protrudes out of the open slot 210. When the first limiting protrusion 322 slides to the third limiting protrusion 411 and abuts against each other, the first sliding part 321 protrudes out of the open slot 210, and the second sliding part 323 is located in the cavity. The positional relationship of the guide block 320, the rotating shaft 310, the open slot 210 and the pen barrel 200 is further shown in Figure 11
[0050] The pushing core mechanism 400 comprises a stop block 410 and a sliding block 420. The stop block 410 has a trapezoidal structure in cross section. The outermost end of the top of the stop block 410 is provided with the third limiting protrusion 411. The sliding block is arranged below the stop block. The sliding block is provided with a sliding slot which is matched with the limiting slot 220 of the inner wall, so that the sliding block moves along the axial direction in the limiting slot 220 of the inner wall. The stop block 410 is designed in an integrated manner with the sliding block. It is easily understood that when the stop block 410 is subjected to the thrust of the guide block 320, the thrust can be transmitted to the sliding block along the axial direction and the displacement of the sliding block can be achieved at the same time. The lower end of the sliding block abuts against the core 600. The bottom of the pen neck 500 is internally provided with an elastic member 510 which is sleeved on the core 600.
[0051] The pen comprises a core retraction state. When the first sliding part 321 is located in the cavity, the first stop portion abuts against the second stop portion, and the second sliding part 323 protrudes out of the open slot 210, the pen is in the core retraction state.
[0052] As shown in Figures 6-10 the pen comprises a core ejection state. When the first sliding part 321 is away from the cavity and completely protrudes out of the open slot 210, the first stop portion abuts against the third stop portion, and the second sliding part 323 is located in the cavity, the pen is in the core ejection state.
[0053] When the guide block 320 in the retracted state is pressed in the radial direction, the guide block 320 under pressure rotates counterclockwise around the rotating shaft 310, the first stop portion and the second stop portion begin to separate, the second sliding portion 323 gradually retracts into the cavity, and the first sliding portion 321 gradually protrudes from the opening slot 210; the first stop portion continuously moves into the cavity and exerts a pushing force on the stop block 410, the stop block 410 under the pushing force moves downward and converts the pushing force into an axial downward pressure, the stop block 410 simultaneously slides downward under pressure, the stop block 410 moves from the P point height to the Q point height, the first stop portion abuts against the third stop portion, the sliding block slides downward, exerts pressure on the refill 600 and drives the refill 600 to slide downward, the bottom of the refill 600 abuts against the elastic member 510, the elastic member 510 changes from the stretched state to the compressed state, and the refill 600 extends from the tail end of the pen neck 500.
[0054] When the guide block 320 in the extended state is pressed in the radial direction, the guide block 320 under pressure rotates clockwise around the rotating shaft 310, the first stop portion and the third stop portion begin to separate, the first sliding portion 321 gradually retracts into the cavity, and the second sliding portion 323 gradually protrudes from the opening slot 210; the first stop portion continuously moves out of the opening slot 210, the pushing force on the stop block 410 gradually weakens, the elastic member 510 changes from the compressed state to the stretched state and provides potential energy for the refill 600, the refill 600 provides an upward pushing force on the sliding block and the stop block 410, and as the second sliding portion 323 gradually slides to the position where the first stop portion abuts against the second stop portion, the stop block 410 returns from the Q point height to the P point height, and the refill 600 retracts from the tail end of the pen neck 500.
