[0018] Clearly, the described embodiments are merely a part of the embodiments of the present application, rather than all the embodiments. Based on the embodiments of the present application, all the other embodiments obtained by those skilled in the art without creative labor fall within the scope of protection of the present application.
[0019] With reference to Figures 1 to 3 The utility model provides an embodiment: neutral pen holder is with integrated rotation formula anti -drop device structure, including the pen tube 1, provides the basis for other components and supports, its outside smooth design is favorable to the smooth sliding of mobile ring 2 on its surface, the outside sliding joint of pen tube 1 has mobile ring 2, mobile ring 2 can slide up and down along the outer surface of pen tube 1. The both sides of mobile ring 2 are respectively slidingly connected with moving rods 3, when being subjected to external force, the sliding of moving rod 3 in mobile ring 2 can transmit power to other components, the far side of two moving rods 3 is fixedly connected with controller 4, and controller 4 transmits the force applied by the user to the moving rod 3 connected thereto. The outside of the near side of two moving rods 3 is provided with spring 7, and spring 7 plays an important role of buffering and resetting. The inner walls of the both sides of mobile ring 2 are respectively fixedly connected with sliding blocks 6, and the sliding blocks 6 move synchronously with the sliding of mobile ring 2. The bottom end of sliding block 6 is fixedly connected with guide block 5, the near side of two sliding blocks 6 is respectively fixedly connected with buckle 8, and the buckle 8 cooperates with inverted triangular ring 9 to realize positioning and locking of rotating rod 10. The bottom end of pen tube 1 is rotatably connected with rotating rod 10, and rotating rod 10 is a key component for realizing the rotation function of the whole device. The top end of rotating rod 10 is fixedly connected with inverted triangular ring 9 inside. The special shape of inverted triangular ring 9 cooperates with buckle 8 to realize accurate control of rotating rod 10.
[0020] With reference to Figures 1 to 3 The bottom end of rotating rod 10 is fixedly connected with buffer pad 11, and when rotating rod 10 rotates or is subjected to external impact, buffer pad 11 can absorb and disperse energy by using the elastic deformation thereof. The bottom end of rotating rod 10 is fixedly connected with pen head 12. When rotating rod 10 rotates, pen head 12 is driven to rotate correspondingly. The bottom end of pen tube 1 is fixedly connected with pen cap 13, and pen cap 13 mainly plays a role of protecting pen head 12. Pen head 12 is slidingly connected to the inner wall of pen cap 13. The bottom end of buffer pad 11 is fixedly connected to the top end of pen head 12, so that buffer pad 11 and pen head 12 form an integral whole and can move synchronously. Meanwhile, buffer pad 11 is slidingly connected to the inner wall of pen cap 13, and in the sliding process of pen head 12, buffer pad 11 also slides along the inner wall of pen cap 13.
[0021] When the pen head 12 is extended or retracted, the buffer pad 11 can further buffer the impact force that can be generated, and the outer part of the buffer pad 11 is slidingly connected to the inner wall of the pen cap 13. The proximal sides of the two moving rods 3 are fixedly connected to the distal sides of the two buckles 8, respectively, and when the moving rods 3 slide in the moving ring 2, the buckles 8 are directly driven to move correspondingly. The outer parts of the two moving rods 3 are slidingly connected to the inner parts of the two guide blocks 5, respectively. The guide blocks 5 provide guidance and support for the sliding of the moving rods 3. The pen barrel 1 is provided with sliding grooves on both sides, and the outer part of the sliding block 6 is slidingly connected to the sliding groove inside the pen barrel 1. When the moving ring 2 slides, the sliding block 6 will slide in the sliding groove. This sliding connection mode ensures the stability and directionality of the movement of the sliding block 6, and also limits the activity range of the sliding block 6. The outer part of the guide block 5 is slidingly connected to the sliding groove inside the pen barrel 1. The guide block 5 also relies on the sliding groove to achieve stable sliding, similar to the sliding block 6. When the sliding block 6 slides in the sliding groove, the guide block 5 will also slide.
[0022] Working principle: the two buckles 8 and the inverted triangular ring 9 are connected and clamped, when fixed, the moving ring 2 drives the buckle 8 to slide in the sliding groove inside the pen barrel 1 through the sliding block 6, when the buckle 8 moves, the inverted triangular ring 9 moves, the outer part of the inverted triangular ring 9 slides in the inner part of the rotating rod 10, and at the same time, the rotating rod 10 moves to the sliding direction through the threaded structure inside the pen barrel 1, when the rotating rod 10 closely fits with the threaded structure, the rotating rod 10 and the pen barrel 1 present a fixed connection relationship, and when the rotating rod 10 moves, the buffer pad 11 avoids the pen barrel 1 and the pen head 12 from colliding, so as to realize the convenience of tightening and avoiding falling off after replacing the pen core for users with smaller hand strength.
