[0064] To make the objectives, technical solutions and advantages of the present invention more clear, the embodiments of the present invention will be described in further detail below with reference to the accompanying drawings.

[0065] Please refer to Figure 1 As shown, the present application provides a side-pressing silent writing tool 1, which may include: a pen core 9, a spring 10, a pen body 3 and a side-pressing mechanism. The spring 10 and the side-pressing mechanism are installed in the pen body 3. The pen body 3 has a relative writing end and an operating end along its axial direction. The writing tool 1 can be transformed between a non-use state in which the pen core 9 is retracted from the writing end into the pen body 3 along the axial direction of the pen body 3 and a use state in which the pen core 9 is extended from the writing end to the pen body 3 along the axial direction of the pen body 3.

[0066] The side pressing mechanism may include a side pressing block 5 , a pressing head 7 , a fixing block 8 , an inner slider 4 and a pressing cap 6 .

[0067] The side pressing block 5 is slidably disposed on the operating end of the pen shaft 3 and protrudes from the surface of the pen shaft 3 .

[0068] The press head 7 can be slidably installed at the operating end of the pen body 3, and has an internal hollow cylindrical wall structure. The wall structure has a sliding groove 71, a symmetrical first snap-fit ​​structure 76 and a second snap-fit ​​structure 77. A pushing portion 75 is provided in the sliding groove 71. The surface of the press head 7 has an extension portion 72, which abuts against the side press block 5 and cooperates with the side press block 5 for the user to press.

[0069] The fixed block 8 is fixedly installed on the pen shaft 3 between the press head 7 and the pen shaft 3. A cylindrical platform 81 extending radially along the pen shaft 3 is provided on the inner side of the fixed block 8. The cylindrical platform 81 passes through the sliding groove 71 of the press head 7 and extends into the interior of the press head 7. The press head 7 can slide relative to the fixed block 8 in the axial direction of the pen shaft 3.

[0070] The inner slider 4 is located inside the pressing head 7 and is rotatably mounted on the cylindrical platform 81 of the fixed block 8. The inner slider 4 has a symmetrical double fishtail structure.

[0071] The pressure cap 6 is assembled at the operating end of the pen barrel 3 and abuts against the fixed block 8 and the side pressing block 5. The pressure cap 6 is provided with a pressure cap 6 boss and a cantilever buckle 62 along the axial direction of the pen barrel 3. The pressure cap 6 is assembled and fixed to the pen barrel 3 through the cantilever buckle 62, and the fixing block 8 and the press head 7 are confined in the pen barrel 3 through the pressure cap 6 boss.

[0072] When the writing tool 1 is converted from a non-use state to a use state, the side pressing block 5 pushes the pushing portion 75 of the pressing head 7, and the pushing portion 75 pushes the double fishtail structure, causing the inner slider 4 to rotate around the cylindrical platform 81 until the double fishtail structure engages with the first engaging structure 76 and the second engaging structure 77.

[0073] When the writing tool 1 is converted from the use state to the non-use state, the side pressing block 5 pushes the pushing portion 75 of the pressing head 7, and the pushing portion 75 pushes the double fishtail structure again, causing the inner slider 4 to continue to rotate around the cylindrical platform 81 until the double fishtail structure is disengaged from the first engaging structure 76 and the second engaging structure 77.

[0074] Please refer to Figure 2 In an embodiment of the present application, the pen holder 3 may further include a detachable neck 2. In this case, the neck 2 forms the writing end of the pen holder 3, and the spring 10 can be assembled within the neck 2. Specifically, the interior of the neck 2 is designed as a multi-step cylindrical cavity, and the refill 9 and spring 10 are assembled within the neck 2. A cylindrical hole is designed at one end of the neck 2 for the tip of the refill 9 to be ejected, and a thread is designed at the other end. The thread of the neck 2 cooperates with the internal thread of the pen holder 3.

[0075] Please refer to Figure 3. Two ribs are provided inside the upper end of the pen barrel 3. The fixed block 8 is designed to be not circular and is assembled in the pen barrel 3. A fixed block retaining rib 31 is provided in the pen barrel 3 to block the two sides of the fixed block 8 to prevent the fixed block 8 from rotating. A pen barrel through groove 32 and a through hole 33 are designed at one end of the pen barrel 3.

[0076] Please refer to Figure 4 The center of the pressure cap 6 is a through hole 33. When the pressing head 7, fixed block 8, and inner slider 4 are assembled inside the pen body 3, the pressure cap 6 passes through the pressing head 7 from the top and presses the top of the fixed block 8. The pressure cap 6 is provided with a pressure cap boss 61. The pressure cap 6 is installed in the pen body through the pressure cap boss 61, which provides an external shield for the pen body through the slot 32 to prevent debris from entering the interior of the writing instrument. The part of the pressure cap 6 that presses the upper end of the fixed block 8 is also provided with two cantilevered buckles 62. The cantilevered buckles 62 cooperate with the through holes 33 at corresponding positions on the pen body 3. After assembly, the pressure cap 6 and the pen body 3 are relatively fixed.

[0077] Please refer to Figure 5 The side pressing block 5 may include a side pressing portion 51, a connecting rib 52 and an assembly portion 53. The assembly portion 53 is cylindrical in design and is assembled on the extension portion 72 on the pressing head 7. The side pressing portion 51 and the assembly portion 53 are connected to form a component by the connecting rib 52.

[0078] Please refer to Figure 6The cylindrical wall structure of the press head 7 is provided with a sliding groove 71 extending from the middle to the tail, and a pushing portion 75 is provided on the top of the sliding groove 71. The inner side of the cylindrical wall structure is also provided with protruding ribs to form a first locking structure 76. A first opening 73 is provided between the first locking structure 76 and the tail of the press head 7. A second opening 74 is provided on the inner side of the wall structure of the press head 7 on the opposite side of the first locking structure 76, and the edge of the second opening 74 close to the head of the press head 7 forms a second locking structure 77. The widths of the first opening 73 and the second opening 74 match the size of the inner slider 4.

[0079] The central surface of the pusher 7 is provided with an extension 72, i.e., a boss of the pusher 7. The mounting portion 53 of the side pressing block 5 is mounted on this boss. For example, when the writing instrument 1 is to be used, the side pressing component can be pressed. This, via the connecting rib 52, causes the side pressing portion 51 to move downward along the axis of the pen body 3. This, in turn, drives the pusher 7 to generate a force acting on the pen refill 9, causing it to extend from the writing end.

[0080] Please refer to Figure 7 and Figure 8 The fixing block 8 is an arc-shaped cylindrical structure, and its arc shape matches the shape of the pen holder 3. An inner hole 43 is provided in the middle of the inner slider 4, and the inner slider 4 is rotatably fixed in the middle position of the cylindrical platform 81 through the inner hole 43.

[0081] The cylindrical platform 81 has a limiting structure for limiting the inner slider 4 in the axial direction of the cylindrical platform 81. For example, the cylindrical platform 81 has a relatively small cross-section in the middle section and relatively large cross-section sections on both sides, thus forming a limiting structure to limit the inner slider 4 in the middle section.

[0082] In an embodiment of the present invention, a boss 811 is provided in the middle of the fixed block 8. The boss 811 of the fixed block 8 cooperates with the inner hole 43 of the inner slider 4 to ensure that the inner slider 4 remains stationary relative to the fixed block 8 in the absence of external forces. When the pusher 7 moves downward, the internal rib of the pusher 7 hits a corner of the double fishtail structure, causing the inner slider 4 to rotate a certain angle relative to the fixed block 8.

[0083] The push head 7 limits the inner slider 4 so that the double fishtail structure is arranged axially along the pen barrel 3.

[0084] When the writing tool 1 is in a non-use state, the first fishtail 41 of the double fishtail structure faces the operating end of the pen shaft 3, and the second fishtail 42 faces the writing end of the pen shaft 3. The double fishtail structure has corner 1 411 of the first fishtail 41, corner 2 412 of the first fishtail 41, corner 3 413 of the second fishtail 42 and corner 414 of the second fishtail 42 in sequence along the rotation direction.

[0085] When the writing tool 1 is converted from the non-use state to the use state, the pressing head 7 is sequentially engaged between the first corner 411 and the second corner 412 by the first engaging structure 76 , and engaged between the third corner 413 and the fourth corner 414 by the second engaging structure 77 .

[0086] When the writing instrument 1 is switched from the use state to the non-use state, the push head 7 releases the engagement of the second engagement structure 77 and the first engagement structure 76 in sequence.

[0087] Specifically, please refer to Figure 9. When the pressing side block 5 moves downward, it drives the pressing head 7 to press downward, and the pushing portion 75 inside the pressing head 7 pushes the second corner 412 of the first fishtail 41, causing it to rotate a certain angle on the cylindrical platform 81 on the fixed block 8.

[0088] When the side button 5 is released, the refill 9 retracts a certain distance under the action of the spring 10. At this point, the fourth corner 414, which faces the second corner 412, is pushed by the bottom surface of the second opening 74 on the pusher 7, causing the inner slider 4 to rotate a certain angle. At this point, the first and second corners 411 and 412 engage with the protruding ribs on the inner side of the wall structure of the pusher 7 (the first engaging structure 76), while the third and fourth corners 413 and 414 engage with the edge of the second opening 74 near the rear of the pusher 7 (the second engaging structure). This is the state where the refill 9 is ejected, and its locked state provides relative force for writing, preventing it from retracting.

[0089] When the side button 5 is pressed again, the pusher 7 pushes angle 1 411, causing the inner slider 4 to rotate a certain angle. The refill 9, now under the force of the spring 10, moves backward, driving the pusher 7 with it. The second engaging mechanism then pushes angle 3 413, causing the inner slider 4 to rotate a certain angle. The positions of angles 1 411 and 2 412 are now interchanged with those of angles 3 413 and 4 414. This constitutes one cycle of pushing the refill out and pushing it back in, and the cycle continues.
