[0026] Further, a rib 421 is protruded on an outer circumferential wall of the shaft shell 42, and a recess 61 is recessed on a position of an inner circumferential wall of the sleeve 60 corresponding to the rib 421, the recess 61 is used for the rib 421 to be embedded, so that the sleeve 60 and the shaft shell 42 are clamped with each other and can be in synchronous rotation, specifically, the number and length of the rib 421 are set according to the actual size of the shaft shell 42, which will not be limited herein, and the number of the recess 61 corresponds to the number of the rib 421.

[0027] Further, the groove 61 extends from the right end of the sleeve 60 to the center of the sleeve 60, and the length of the groove 61 is greater than the length of the rib 421, so that when the fixed shaft 10 is separated from the insertion hole 21, the right end of the damping rotating shaft assembly 40 is pressed to move the fixed part 20, the connecting part 30, the switching part 50 and the damping rotating shaft assembly 40 to the left end of the sleeve 60 at the same time, so that the damping rotating shaft assembly 40 is completely retracted into the sleeve 60.

[0028] Further, the sleeve 60 is fixedly connected with the seat ring 70, and the cover plate 80 is provided with a connecting hole 81 at the right end of the sleeve 60, and the shaft shell 42 of the damping rotating shaft assembly 40 is rotatably inserted into the connecting hole 81, so that the shaft shell 42 is pivotally connected with the cover plate 80, and the sleeve 60 and the shaft shell 42 are clamped with each other, so that the sleeve 60 and the shaft shell 42 can rotate synchronously, and the sleeve 60 is fixedly connected with the seat ring 70, so that the seat ring 70 is pivotally connected with the cover plate 80.

[0029] Further, the fixed shaft 10 is further provided with a second clamping groove 12, and the pressing clamping assembly 22 comprises a button 221, and the right end of the button 221 is provided with a clamping part 222, the clamping part 222 extends to the insertion hole 21, and is provided with a first protrusion 2222 and a first clamping groove 2221 in sequence, the first protrusion 2222 is used for clamping the second clamping groove 12, so that when the button 221 is pressed, the fixed shaft 10 is moved out of the second clamping groove 12, and the fixed shaft 10 is located in the first clamping groove 2221, so that the fixed shaft 10 moves in the axial direction; specifically, the inner side edge of the clamping part 222 is arc-shaped, so as to form the first clamping groove 2221, and when the button 221 is not pressed, the first protrusion 2222 is clamped in the second clamping groove 12, so as to limit the axial movement of the fixed shaft 10, and when the button 221 is pressed, the clamping part 222 moves to the right, so that the fixed shaft 10 enters the first clamping groove 2221, and if the clamping part 33 is not clamped in the first clamping groove 11 at this time, the fixed shaft 10 is relatively moved downward from the first clamping groove 2221 by moving the fixed part 20 upward, and then the fixed shaft 10 is separated from the insertion hole 21 of the fixed shaft 10, and specifically, the clamping part 222 is two and is symmetrically arranged on the same horizontal plane, so as to clamp the fixed shaft 10 more firmly.

[0030] Further, the press-fit assembly 22 further comprises a compression spring 223 fixedly arranged between the button 221 and the fixing member 20 to elastically push the button 221 and the fixing member 20 outward, so that the first protrusion 2222 returns to the second clamping groove 12 to limit the fixed shaft 10 from moving in the axial direction, and the fixing member 20 pushes the damping shaft assembly 40 extending out of the right end of the sleeve 60 to rotate and connect with the connecting hole 81 of the cover plate 80; specifically, the compression spring 223 pushes the fixing member 20, so that the fixing member 20 pushes the connecting member 30, and then pushes the damping shaft assembly 40 extending out of the right end of the sleeve 60, and the premise that the compression spring 223 can push the fixing member 20 is that the fixed shaft 10 is not inserted into the insertion hole 21, if the fixed shaft 10 is inserted into the insertion hole 21, the compression spring 223 will be blocked from moving; the reason that the fixing member 20, the connecting member 30 and the damping shaft assembly 40 can displace in the sleeve 60 is that the sleeve 60 has a cylindrical cavity, the fixing member 20, the connecting member 30 and the damping shaft assembly 40 fit with the cylindrical cavity, and because the length of the groove 61 in the sleeve 60 is greater than the length of the rib 421 of the shaft shell 42, whether the damping shaft assembly 40 is pressed to retract or the compression spring 223 pushes the fixing member 20 to make the damping shaft assembly 40 extend out of the sleeve 60, the rib 421 of the shaft shell 42 of the damping shaft assembly 40 moves in the length direction of the groove 61 in the groove 61, but the premise is that the fixed shaft 10 is not inserted into the insertion hole 21.

[0031] Further, the left end of the sleeve 60 extends towards the central axis direction to form a first blocking part 62, the right side of the button 221 extends radially to form a second blocking part 2211, and the compression spring 223 pushes against the button 221 so that the second blocking part 2211 abuts against the first blocking part 62 to prevent the button 221 from being separated from the sleeve 60; specifically, a hole is left in the middle of the first blocking part 62 for the left end of the button 221 to pass through, so that the left end of the button 221 protrudes out of the sleeve 60, facilitating the user to press it, and the abutment of the second blocking part 2211 against the first blocking part 62 prevents the button 221 from being separated from the sleeve 60, preventing the button 221 from being pressed to perform one-key quick disassembly; specifically, the assembly of the retainer ring 70 and the cover plate 80 is more convenient and fast before the fixed shaft 10 is inserted into the insertion hole 21, and since the length of the groove 61 is greater than the length of the rib 421, the right end of the damping shaft assembly 40 can be pressed to move the damping shaft assembly 40, the switching piece 50, the connecting piece 30 and the fixed piece 20 to the left, and at this time, since the second blocking part 2211 abuts against the first blocking part 62, the compression spring 223 is in a compressed state, and there is an outward tension on the fixed piece 20, the connecting piece 30, the switching piece 50 and the damping shaft assembly 40, if the right side of the sleeve 60 is aligned with the connecting hole 81 of the cover plate 80 at this time, and the pressing on the damping shaft assembly 40 is released, the compression spring 223 will push the fixed piece 20, the connecting piece 30, the switching piece 50 and the damping shaft assembly to the right, so that the right end of the shaft shell 42 of the damping shaft assembly 40 is inserted into the connecting hole 81, and the assembly of the retainer ring 70 and the cover plate 80 can be completed more conveniently and quickly.

[0032] Further, the shaft core assembly 41 is provided with a second protrusion 411, the right end of the switching piece 50 is provided with a first opening 52 and a second opening 53, the second opening 53 is provided on the right side of the first opening 52, and when the switching piece 50 slides to the left, the second protrusion 411 is clamped into the second opening 53, and when the switching piece 50 slides to the right, the second protrusion 411 is clamped into the first opening 52; specifically, when the switching piece 50 slides to the left, the second protrusion 411 slides into the second opening 53 to limit the position of the switching piece 50 and prevent it from sliding to the right by itself, which leads to the slow-falling state entering the non-slow-falling state, contrary to the user's intention and affecting the user's experience, and when the switching piece 50 slides to the right, the second protrusion 411 slides into the first opening 52 to limit the position of the switching piece 50 and prevent it from sliding to the left by itself, which leads to the non-slow-falling state entering the slow-falling state, contrary to the user's intention and affecting the user's experience; specifically, the second protrusion 411 is in the shape of a hemisphere to facilitate sliding into and out of the first opening 52.

[0033] Further, the sleeve 60 is provided with a strip-shaped avoiding opening 63, a first through hole 64 and a second through hole 65. The avoiding opening 63 is located on the moving path of the fixed shaft 10 during rotation of the sleeve 60, so as to avoid the fixed shaft 10 during rotation of the sleeve 60. The first through hole 64 is used for exposing the threaded hole 31. The second through hole 65 is used for exposing the first opening 52 and the second opening 53. Specifically, the avoiding opening 63 can not only avoid the fixed shaft 10, but also can be used for inserting the fixed shaft 10 into the insertion hole 21. In addition, the avoiding opening 63 can also limit the excessive rotation of the seat ring 70. When the seat ring 70 rotates to the position, the end wall of the avoiding opening 63 abuts against the outer peripheral wall of the fixed shaft 10, so that the seat ring 70 cannot continue to rotate. Specifically, the first through hole 64 can rotate with the sleeve 60 and align with the threaded hole 31. The user can use a tool to extend into the first through hole 64 and the threaded hole 31, and rotate the pushing piece 32 inwardly or outwardly, so as to switch the quick release state or the non-quick release state. Specifically, when the pushing piece 32 is rotated outwardly, the pushing piece 32 moves outwardly relative to the threaded hole 31. The elastic piece 35 pushes the clamping piece 33 outwardly, so that the clamping piece 33 exits the insertion hole 21. At this time, the quick release assembly enters the quick release state, and the fixed shaft 10 can be quickly released by pressing the clamping assembly 22. When the pushing piece 32 is rotated inwardly, the pushing piece 32 moves inwardly relative to the threaded hole 31. The pushing piece 32 pushes the clamping piece 33, so that the clamping piece 33 is inserted into the first clamping groove 11. The quick release assembly enters the non-quick release state. Specifically, the second through hole 65 can rotate with the sleeve 60. When the user rotates the second through hole 65 to the corresponding position of the first opening 52 and the second opening 53, the first opening 52 and the second opening 53 are exposed. The user inserts a tool into the sleeve 60, and slides the switching piece 50 to the left, so that the first clamping part 51 and the second clamping part 34 are clamped and fixed. The slow release state is entered. Or, the user slides the switching piece 50 to the right, so that the first clamping part 51 and the second clamping part 34 are loosened. The non-slow release state is entered.
