Description

Technical Field

[0001] The present application relates to the field of tea sets, and in particular to a travel amplification structure for a cup cover, a cup cover and a tea cup. Background Art

[0002] A teacup is a utensil used to brew tea. When the brewing time is too long or too short, the taste of the tea will be reduced, so it is crucial to control the brewing time reasonably.

[0003] The related technology discloses a teacup, comprising a cup body and a cup cover, wherein the cup cover is provided with a magnetic attraction mechanism for adsorbing a tea bin; when it is necessary to brew tea, the magnetic attraction of the magnetic attraction mechanism to the tea bin is released, and the tea bin falls into the water in the cup body; when it is necessary to separate tea and water, the cup body is inverted and returned to an upright position, and the tea bin is adsorbed by the magnetic attraction mechanism on the cover body to achieve tea and water separation; when it is necessary to continue brewing tea, the magnetic attraction of the magnetic attraction mechanism to the tea bin is released, and the tea bin falls into the water in the cup body to continue brewing tea.

[0004] With respect to the above-mentioned related technologies, the inventors believe that the following defects exist: although the teacup in the related technology can reasonably control the time of brewing tea, after the tea is brewed, the user first needs to manually turn the teacup upside down so that the tea compartment is adsorbed by the magnetic suction mechanism on the cup lid. At this time, the user needs to turn the teacup upside down again so that the cup lid is located on the top of the cup body, thereby reducing the convenience of using the teacup. Utility Model Content

[0005] In order to improve the convenience of using a teacup, the present application provides a stroke amplification structure for a cup cover, a cup cover and a teacup.

[0006] The stroke amplification structure for a cup cover provided in the present application adopts the following technical solution:

[0007] A stroke amplification structure for a cup cover, comprising:

[0008] A cup cover base, wherein a through hole is provided on the cup cover base;

[0009] A traction rope, one end of which is connected to the cup cover base, and the other end of which passes through the through hole and is used to be connected to the tea brewing component;

[0010] A stroke amplification mechanism, the stroke amplification mechanism comprising a gear structure and a connecting rod structure, the gear structure and the connecting rod structure are linked to each other, and the traction rope is connected to the stroke amplification mechanism;

[0011] A driving mechanism, wherein the driving mechanism is used to drive the stroke amplification mechanism to operate, wherein the stroke amplification mechanism causes the traction rope to bend and deform during operation, and the traction rope drives the tea brewing component to move toward a direction close to the cup cover base when bent and deformed, and the output stroke of the traction rope is greater than the input stroke of the driving mechanism.

[0012] By adopting the above technical solution, when the tea is brewed, the driving mechanism is used to drive the gear structure to operate and thus drive the connecting rod structure to operate. The connecting rod structure causes the traction rope to bend and deform during operation, and the traction rope drives the tea brewing piece to move in the direction close to the base of the cup cover when it is bent and deformed. Since the movement stroke of the driving mechanism is smaller than the movement stroke of the tea brewing piece, the driving mechanism can not only move the tea brewing piece from the cup body to the position of the cup cover, thereby realizing the separation of tea and water; at the same time, the driving mechanism can also move the tea brewing piece from the cup cover to the cup body, thereby realizing quick tea brewing. Compared with the background technology, during the process of brewing tea, the user does not need to invert the teacup twice, thereby improving the convenience of using the teacup.

[0013] Optionally, the gear structure includes a linkage gear, which is rotatably connected to the cup cover base; the connecting rod structure includes a linkage rack, which is slidingly matched with the cup cover base; the linkage gear and the linkage rack are meshed with each other, and the linkage rack drives the stroke amplification mechanism to operate when sliding.

[0014] By adopting the above technical solution, since the linkage gear and the linkage rack are meshed with each other, the linkage gear is driven to rotate through the driving mechanism. When the linkage gear rotates, it drives the linkage rack to slide. When the linkage rack slides, it drives the stroke amplification mechanism to operate, thereby driving the tea brewing piece to move toward or away from the cup cover base.

[0015] Optionally, the stroke amplification mechanism includes a linkage component and a stroke amplification component, the linkage rack drives the linkage component to operate during sliding, the linkage component is used to drive the stroke amplification component to operate, and the stroke amplification component causes the traction rope to bend and deform during operation.

[0016] By adopting the above technical solution, the linkage gear is driven to rotate through the driving mechanism, and the linkage gear drives the linkage rack to slide. When the linkage rack slides, the linkage component is driven to run. When the linkage component runs, the stroke amplification component is driven to run. When the stroke amplification component is running, the traction rope is bent and deformed, thereby realizing the movement of the tea brewing part from the cup body to the position of the cup cover, thereby realizing the separation of tea and water.

[0017] Optionally, the stroke amplification component includes two followers, both of which are slidably engaged with the cup cover base; the traction rope passes through the followers, and the traction rope is slidably engaged with the followers; the linkage component is used to drive the stroke amplification component to operate, so that the two followers in the stroke amplification component move towards or away from each other.

[0018] By adopting the above technical solution, since the traction rope passes through the follower and the traction rope and the follower slide and cooperate with each other, when the linkage component drives the stroke amplification component to operate, when the two followers in the stroke amplification component move in directions away from each other, the two followers drive the traction rope to bend and deform. Since the total length of the traction rope remains unchanged, the traction rope drives the tea brewing component to rise during the bending and deformation process, so that the tea brewing component moves from the cup body to the position of the cup cover base, thereby realizing the separation of tea and water; when it is necessary to brew tea again, the stroke amplification component is driven to operate by the linkage component, so that the two followers in the stroke amplification component move in directions approaching each other, thereby reducing the degree of bending and deformation of the traction rope, and the tea brewing component falls into the cup body under the action of its own gravity, thereby realizing re-brewing of tea.

[0019] Optionally, the linkage assembly includes an active member and two connecting members, the active member slidingly cooperates with the cup lid base, the driving mechanism is used to drive the active member to slide, and the motion trajectory of the active member and the motion trajectory of the driven member have an intersection; one end of the connecting member is rotatably connected to the active member, and the other end of the connecting member is rotatably connected to the driven member.

[0020] By adopting the above technical solution, since the motion trajectory of the active member and the motion trajectory of the driven member have an intersection; one end of the connecting member is rotationally connected to the active member, and the other end of the connecting member is rotationally connected to the driven member. Therefore, when the driving mechanism drives the active member to slide, the active member simultaneously drives one end of the two connecting members to move along the motion trajectory of the active member, and the other ends of the two connecting members respectively drive the two driven members to move in the direction of approaching or moving away from each other, thereby changing the bending deformation of the traction rope.

[0021] Optionally, the motion trajectory of the active member and the motion trajectory of the driven member are perpendicular to each other.

[0022] By adopting the above technical solution, since the movement trajectory of the active member and the movement trajectory of the driven member are perpendicular to each other, the active member can drive the two driven members to move a greater distance during the movement. Therefore, when the length of the traction rope remains unchanged, the movement stroke of the driving mechanism is further reduced.

[0023] Optionally, a support seat is fixedly provided on the cup cover base, the active member abuts against the support seat, and the active member and the support seat are slidably matched.

[0024] By adopting the above technical solution, the support seat not only supports the active part, but also guides the active part, thereby increasing the stability of the active part's movement.

[0025] Optionally, the connecting member includes a connecting rod, a first sleeve and a second sleeve, one end of the connecting rod is fixedly connected to the first sleeve, and the other end of the connecting rod is fixedly connected to the second sleeve; the first sleeve is rotationally connected to the active member, the second sleeve is rotationally connected to the driven member, and the length direction of the connecting rod intersects with the motion trajectory of the first sleeve.

[0026] By adopting the above technical solution, since the length direction of the connecting rod intersects with the motion trajectory of the first sleeve, the active member drives the first sleeve to move during the movement, and at the same time makes the sleeve and the active member rotate relative to each other. The sleeve drives the connecting rod to move during the movement, and the connecting rod drives the second sleeve to move. Since the second sleeve is rotationally connected to the driven member, the second sleeve drives the driven member to move during the movement.

[0027] Optionally, the active part includes an active block, the active block is slidingly matched with the cup cover base, and the driving rack is fixedly connected to the active block; an active rod is provided on the active block; the first sleeve is sleeved on the active rod and is rotatably connected to the active rod.

[0028] By adopting the above technical solution, the active member drives the active rod to move when it moves, the active rod drives the first sleeve to rotate around the active rod when it moves, the first sleeve drives the connecting rod to move when it rotates, and the other end of the connecting rod drives the driven member to move.

[0029] Optionally, the follower includes a follower block and a follower rod, the follower block is slidably matched with the cup cover base; the follower rod is fixed on the follower block, and the second sleeve is sleeved on the follower rod and rotatably connected to the follower rod.

[0030] By adopting the above technical solution, the connecting rod drives the second sleeve to move when it moves. Since the second sleeve is sleeved on the driven rod and is rotatably connected with the driven rod, the second sleeve drives the driven rod to move when it moves. When the driven rod moves, it drives the driven block and the cup cover base to slide relative to each other.

[0031] Optionally, a guide mechanism is provided on the cup cover base, and the driven block is slidably engaged with the guide mechanism.

[0032] By adopting the above technical solution, the guide mechanism has a guiding effect on the driven block, thereby increasing the sliding stability of the driven block.

[0033] Optionally, there are multiple groups of the stroke amplification components, and the multiple groups of the stroke amplification components are arranged at intervals on the active parts of the linkage component, and the traction rope passes through the driven parts of the multiple groups of stroke amplification components in sequence.

[0034] By adopting the above technical solution, since there are multiple groups of stroke amplification components, the multiple groups of stroke amplification components are arranged at intervals on the active parts of the linkage components, and the traction rope passes through the multiple groups of stroke amplification components in turn, the traction rope can be bent and deformed multiple times by the driving mechanism running through the multiple groups of stroke amplification components at the same time, thereby further reducing the movement stroke of the driving mechanism.

[0035] A cup cover comprises the above-mentioned stroke amplification structure for the cup cover, and also comprises a top cover, wherein the top cover is arranged on the cup cover base, and the stroke amplification mechanism is located inside the top cover; the driving mechanism is located on the top or side of the top cover, and the control method of the driving mechanism is pushing, pulling, pressing or rotating.

[0036] By adopting the above technical solution, the cup cover base has a protective effect on the stroke amplification mechanism, which not only increases the cleanliness of the surface of the stroke amplification mechanism, but also extends the service life of the stroke amplification mechanism and the linkage mechanism; at the same time, since the driving mechanism is located at the top or side of the top cover, and the control method of the driving mechanism is push-pull or press or rotate, a variety of control methods can be used to drive the traction rope to bend and deform.

[0037] Optionally, a reset mechanism is provided on the top cover, and the reset mechanism is used to drive the stroke amplification mechanism and / or the driving mechanism to reset.

[0038] By adopting the above technical solution, after the stroke amplification mechanism or the driving mechanism is running, the reset mechanism can reset the stroke amplification mechanism or the driving mechanism.

[0039] Optionally, the reset mechanism is a reset spring, one end of the reset spring abuts against the top cover or the cup cover base, and the other end of the reset spring abuts against the stroke amplification mechanism and / or the driving mechanism. When the stroke amplification mechanism and / or the driving mechanism drive the traction belt to be retracted, the stroke amplification mechanism and / or the driving mechanism squeeze the reset spring, and the reset spring stores elastic potential energy. When the reset spring releases the elastic force, the stroke amplification mechanism and / or the driving mechanism returns to its initial position.

[0040] By adopting the above technical solution, since one end of the return spring abuts against the top cover or the cup cover base, and the other end of the return spring abuts against the stroke amplification mechanism and / or the driving mechanism, the stroke amplification mechanism or the driving mechanism squeezes the return spring during operation, so that the return spring stores elastic potential energy. When the return spring releases the elastic force, the stroke amplification mechanism and / or the driving mechanism returns to the initial position, thereby increasing the convenience of the user in making tea.

[0041] Optionally, the top cover is covered on the cup cover base; the driving mechanism includes an annular internal gear, which is fixed inside the top cover, and the annular internal gear is meshed with the linkage gear; the top cover is rotated by applying external force from the side or top of the top cover, thereby driving the stroke amplification mechanism to operate.

[0043] Optionally, the top cover is fixedly connected to the cup cover base; the driving mechanism includes a rotating grip, which is fixedly connected to the linkage gear; a rotating hole is provided on the top cover, the rotating grip passes through the rotating hole, and one end of the rotating grip protrudes from the top cover; the grip is rotated by applying external force from the top of the top cover, thereby driving the stroke amplification mechanism to operate.

[0044] By adopting the above technical scheme, when the tea is brewed, the holding piece is rotated by applying external force from the top of the top cover, and the rotating holding piece drives the linkage gear to rotate. The linkage gear drives the linkage rack to slide when rotating, and the linkage rack drives the active member to slide along the length direction of the slide groove when sliding. The active member drives the stroke amplification mechanism to operate when sliding, and the stroke amplification mechanism causes the traction rope to bend and deform multiple times during operation, thereby driving the tea bin to rise and realizing the separation of tea and water; when it is necessary to brew tea again, the rotating holding piece is rotated in the opposite direction, thereby driving the linkage gear to rotate in the opposite direction, and the linkage gear drives the linkage rack to slide in the opposite direction, thereby reducing the bending deformation of the traction rope and realizing re-brewing of tea.

[0045] Optionally, the top cover is covered on the cup cover base; the driving mechanism includes a push-pull seat and a driving rack, the top cover is provided with a slide groove, the push-pull seat slides in cooperation with the slide groove, and the top of the push-pull seat protrudes from the surface of the top cover; the driving rack is fixed on the push-pull seat, and the driving rack is meshed with the linkage gear; the push-pull seat is pushed by applying external force from the top of the top cover, thereby driving the stroke amplification mechanism to operate.

[0046] By adopting the above technical scheme, when the tea is brewed, the push-pull seat is pushed by applying external force from the top of the top cover, so that the push-pull seat slides along the length direction of the slide groove, and the push-pull seat drives the driving rack to slide along the length direction of the slide groove; since the driving rack and the linkage gear are meshed with each other, the driving rack drives the linkage gear to rotate when sliding, and the linkage gear drives the linkage rack to slide when rotating, and the linkage rack drives the active part to slide along the length direction of the slide groove when sliding, and the active part drives the stroke amplification mechanism to operate when sliding, and the stroke amplification mechanism causes the traction rope to bend and deform multiple times during operation, thereby driving the tea bin to rise and realizing the separation of tea and water; when it is necessary to brew tea again, the push-pull seat is pushed in the opposite direction, and the push-pull seat drives the driving rack to slide in the opposite direction, thereby driving the linkage gear to rotate in the opposite direction, and the linkage gear drives the linkage rack to slide in the opposite direction, thereby reducing the bending deformation of the traction rope, and realizing re-brewing of tea.

[0047] Optionally, the driving mechanism also includes a push-pull block, one end of which is fixedly connected to the push-pull seat; a first guide hole is also provided on the top cover, and the other end of the push-pull block passes through the first guide hole, and the push-pull block is slidably matched with the cup cover base; the push-pull block is pushed or pulled by applying external force from the side of the top cover, thereby driving the stroke amplification mechanism to operate.

[0048] By adopting the above technical solution, the push-pull block is pushed by applying external force from the side of the top cover, which not only can separate the tea brewing and the tea water, but also can drive the push-pull seat to slide back and forth by pushing the push-pull block, further increasing the convenience of tea brewing.

[0049] Optionally, the driving mechanism also includes a pressing seat, and the top cover is also provided with a lifting groove that is interconnected with the sliding groove, and the pressing seat slides in cooperation with the lifting groove; the pressing seat is provided with a first inclined surface, and the push-pull seat is provided with a second inclined surface, and the first inclined surface abuts against the second inclined surface; the pressing seat is pressed by applying external force from the top of the top cover, thereby driving the stroke amplification mechanism to operate.

[0050] By adopting the above technical scheme, the pressing seat and the lifting groove are slidably matched, and the pressing seat is pressed by applying external force from the top of the top cover, so that the pressing seat moves in the direction close to the push-pull seat. Since a first inclined surface is provided on the pressing seat and a second inclined surface is provided on the push-pull seat, the first inclined surface abuts against the second inclined surface. Therefore, the pressing seat drives the push-pull seat to slide along the length direction of the slide groove, and the push-pull seat drives the driving rack to slide along the length direction of the slide groove. The driving rack drives the linkage gear to rotate when sliding, and the linkage gear drives the linkage rack to slide when rotating. The linkage rack drives the active part to slide along the length direction of the slide groove when sliding, and the active part drives the stroke amplification mechanism to operate when sliding. When the stroke amplification mechanism is running, the traction rope is bent and deformed multiple times, thereby driving the tea bin to rise, thereby realizing the separation of tea and water.

[0052] By adopting the above technical solution, when the tea is brewed, in the process of pressing the pressing seat, not only can the tea and water be separated, but also because one end of the pulling member is fixedly connected to the active member and the other end of the pulling member passes through the second guide hole, the active member drives the pulling member to slide along the length direction of the slide groove during the sliding process, and the guide hole guides the pulling member, thereby increasing the sliding stability of the pulling member; when the tea is brewed, the pulling member is pulled in the opposite direction by applying an external force from the side of the top cover, and the pulling member drives the active member to slide, and the active member restores the stroke amplification mechanism to the initial position when sliding, thereby reducing the bending deformation of the traction rope and realizing re-brewing of tea.

[0053] Optionally, a positioning mechanism is provided on the cup cover, and when the traction rope drives the tea brewing component to move when it is bent and deformed, the positioning mechanism has a fixing effect on the stroke amplification mechanism or the driving mechanism.

[0054] By adopting the above technical solution, when the traction rope drives the tea brewing component to move during bending and deformation, the positioning mechanism has a fixing effect on the active component. Therefore, after the tea is brewed, the stroke amplification mechanism or the driving mechanism is fixed by the positioning mechanism so that the stroke amplification mechanism or the driving mechanism will not operate, so that the traction rope always maintains the maximum deformation amount, thereby ensuring that the tea brewing component is located outside the tea.

[0055] Optionally, the positioning mechanism is positioned by magnetic attraction, sleeve connection or snap connection.

[0056] By adopting the above technical solution, magnetic positioning is easy to use and does not require complicated operation procedures. You only need to place it on the object to be positioned, and it will be automatically adsorbed without moving or shaking, which is more stable; the use of ring positioning or buckle positioning has the advantages of convenience, speed and diverse styles.

[0057] A teacup comprises the above-mentioned cup cover and a cup body, wherein the cup cover is fitted on the cup body, and the tea brewing component is located inside the cup body.

[0058] By adopting the above technical solution, since the tea brewing component is located in the cup body, when the cup body is filled with a proper amount of boiling water, the travel amplification structure for the cup cover in the cup cover can not only move the tea brewing component in the cup body to the cup cover position, but also move the tea brewing component from the cup cover position into the cup body, so that there is no need to invert the cup body during the tea brewing process, thereby improving the convenience of using the teacup.

[0059] Optionally, a first magnetic component is fixedly provided on one end of the traction rope, and a second magnetic component is fixedly provided on the tea brewing component, and the first magnetic component and the second magnetic component are connected by magnetic attraction, sleeve connection or clamping.

[0060] By adopting the above technical solution, the first magnetic component and the second magnetic component are connected by magnetic attraction, sleeve connection or clip connection, which can not only fix the tea brewing component to the free end of the traction rope, but also increase the convenience of users in installing and disassembling the tea brewing component.

[0061] Optionally, a sealed channel is fixedly provided on the cup cover base, the first magnetic attraction component is movably provided in the sealed channel, and the tea brewing component is movably provided outside the sealed channel.

[0062] By adopting the above technical solution, since the first magnetic component is movably arranged in the sealed channel, the sealed channel has a barrier effect on tea, thereby ensuring that the traction rope and the first magnetic component will not be soaked by the tea; at the same time, since the tea brewing component is movably arranged outside the sealed channel, it is convenient to brew tea, and at the same time, the magnetic attraction force between the first magnetic component and the second magnetic component facilitates the movement of the tea brewing component in the cup body.

[0063] In summary, the present application includes at least one of the following beneficial technical effects:

[0064] 1. When the tea is brewed, the driving mechanism is used to drive the linkage gear to rotate to drive the stroke amplification mechanism to move, thereby driving the traction rope to move, so that the traction rope is bent and deformed multiple times. When the traction rope is bent and deformed, it drives the tea brewing part to move in the direction close to the base of the cup cover; because the movement stroke of the driving mechanism is smaller than the movement stroke of the tea brewing part, the driving mechanism can not only move the tea brewing part from the cup body to the position of the cup cover, thereby realizing the separation of tea and water; at the same time, the driving mechanism can also move the tea brewing part from the cup cover to the cup body, thereby realizing fast tea brewing; compared with the background technology, in the process of brewing tea, the user does not need to invert the teacup twice, thereby improving the convenience of using the teacup;

[0065] 2. The cup cover base has a protective effect on the stroke amplification mechanism and the linkage mechanism, which not only increases the cleanliness of the surface of the stroke amplification mechanism and the linkage mechanism, but also prolongs the service life of the stroke amplification mechanism and the linkage mechanism;

[0066] 3. Since the tea brewing component is located in the cup body, when the cup body is filled with a proper amount of boiling water, the travel amplification structure for the cup cover in the cup cover can not only move the tea brewing component in the cup body to the cup cover position, but also move the tea brewing component from the cup cover position into the cup body, so that there is no need to invert the cup body during the tea brewing process, which improves the convenience of using the teacup.

In this embodiment, the tea brewing part 9 is used to hold tea leaves, and the specific tea brewing part 9 can be a tea warehouse or a tea bag.

[0089] Reference Figure 3 and Figure 4 The stroke amplification structure for the cup cover also includes a stroke amplification mechanism 3, which is arranged on the cup cover base 1, and the traction rope 2 is connected to the stroke amplification mechanism 3. Specifically, the stroke amplification mechanism 3 includes a gear structure and a connecting rod structure, which are linked to each other, and the traction rope 2 passes through the connecting rod structure. The connecting rod structure causes the traction rope 2 to bend and deform multiple times during operation, and the traction rope 2 drives the tea brewing component 9 to move toward the direction close to the cup cover base 1 when bending and deforming.

[0090] The gear structure includes a linkage gear 41, which is rotatably connected to the cup cover base 1. The connecting rod structure includes a linkage rack 42, which is slidably matched with the cup cover base 1. The linkage gear 41 and the linkage rack 42 are meshed with each other, and the linkage rack 42 drives the stroke amplification mechanism 3 to operate when sliding. The linkage gear 41 and the linkage rack 42 are combined to form a linkage mechanism 4. The linkage gear 41 is driven to rotate by the driving mechanism 5, and the linkage gear 41 drives the linkage rack 42 to slide when rotating, and the linkage rack 42 drives the stroke amplification mechanism 3 to operate when sliding, thereby driving the tea brewing component 9 to move toward or away from the cup cover base 1.

[0091] Specifically, a bearing platform 15 is fixedly provided on the upper surface of the cup cover base 1, and a first rotating shaft 16 is fixedly provided on the upper surface of the bearing platform 15, and the first bearing extends in the vertical direction. The linkage gear 41 is sleeved on the first rotating shaft 16, the linkage gear 41 is rotationally connected with the first rotating shaft 16, and the lower surface of the linkage gear 41 abuts against the top of the bearing platform 15, and the bearing platform 15 has an upward supporting effect on the linkage gear 41. The linkage rack 42 is slidably matched with the cup cover base 1; the linkage gear 41 and the linkage rack 42 are meshed with each other, and the linkage rack 42 drives the stroke amplification mechanism 3 to operate when sliding.

[0092] The stroke amplification structure for the cup cover also includes a driving mechanism 5, which is used to drive the stroke amplification mechanism 3 to operate. The stroke amplification mechanism 3 causes the traction rope 2 to bend and deform during operation. When the traction rope 2 is bent and deformed, it drives the tea brewing component 9 to move toward the direction close to the cup cover base 1. Specifically, the driving mechanism 5 is used to drive the gear structure to operate so as to drive the connecting rod structure to operate. During operation, the connecting rod structure causes the traction rope 2 to bend and deform. When the traction rope 2 is bent and deformed, it drives the tea brewing component 9 to move toward the direction close to the cup cover base 1. The output stroke of the traction rope 2 is greater than the input stroke of the driving mechanism 5.

[0093] When the tea is brewed, the driving mechanism 5 is used to drive the gear structure to operate, thereby driving the connecting rod structure to operate, so that the traction rope 2 is bent and deformed multiple times. When bending and deforming, the traction rope 2 drives the tea brewing component 9 to move in the direction close to the cup cover base 1; because the movement stroke of the driving mechanism 5 is smaller than the movement stroke of the tea brewing component 9, the driving mechanism 5 can not only move the tea brewing component 9 from the cup body 8 to the position of the cup cover, thereby realizing the separation of tea and water; at the same time, the driving mechanism 5 can also move the tea brewing component 9 from the cup cover to the cup body 8, thereby realizing fast tea brewing.

[0094] Reference Figure 3 The stroke amplification mechanism 3 includes a linkage component 31 and a stroke amplification component 32. The linkage rack 42 drives the linkage component 31 to operate during the sliding process. The linkage component 31 is used to drive the stroke amplification component 32 to operate. The stroke amplification component 32 bends and deforms the traction rope 2 during the operation. The linkage gear 41 is driven to rotate by the driving mechanism 5. The linkage gear 41 drives the linkage rack 42 to slide. When the linkage rack 42 slides, the linkage component 31 is driven to operate. When the linkage component 31 operates, the stroke amplification component 32 is driven to operate. When the stroke amplification component 32 operates, the traction rope 2 is bent and deformed, thereby realizing the movement of the tea brewing component 9 from the cup body 8 to the position of the cup cover, thereby realizing the separation of tea and water.

[0095] In this embodiment, each stroke amplification component 32 includes two followers 321, and the two followers 321 are both slidably matched with the cup cover base 1, and the sliding direction of the followers 321 is the second direction. The traction rope 2 passes through the followers 321, and the traction rope 2 and the followers 321 are slidably matched. Specifically, a through hole 3213 or a ring or a hook can be provided at one end of the two followers 321 close to each other, and the traction rope 2 passes through the through hole 3213 or the ring or the hook. The linkage component 31 is used to drive the stroke amplification component 32 to operate, so that the two followers 321 in the stroke amplification component 32 move in a direction close to or away from each other. When the linkage component 31 drives the stroke amplification component 32 to operate, when the two followers 321 in the stroke amplification component 32 move in directions away from each other, the two followers 321 drive the traction rope 2 to bend and deform. Since the total length of the traction rope 2 remains unchanged, the traction rope 2 drives the tea brewing component 9 to rise during the bending and deformation process, so that the tea brewing component 9 moves from the cup body 8 to the position of the cup cover base 1, thereby realizing the separation of tea and water; when it is necessary to brew tea again, the linkage component 31 drives the stroke amplification component 32 to operate, so that the two followers 321 in the stroke amplification component 32 move in a direction close to each other, thereby reducing the degree of bending and deformation of the traction rope 2, and the tea brewing component 9 falls into the cup body 8 under the action of its own gravity, thereby realizing re-brewing of tea.

[0096] The linkage assembly 31 includes an active member 311 and two connecting members 312. The active member 311 is slidably matched with the cup cover base 1. The driving mechanism 5 is used to drive the active member 311 to slide along the first direction. The motion trajectory of the active member 311 and the motion trajectory of the driven member 321 have an intersection. One end of the connecting member 312 is rotationally connected to the active member 311, and the other end of the connecting member 312 is rotationally connected to the driven member 321. Since the motion trajectory of the active member 311 and the motion trajectory of the driven member 321 have an intersection. One end of the connecting member 312 is rotationally connected to the active member 311, and the other end of the connecting member 312 is rotationally connected to the driven member 321. Therefore, when the driving mechanism 5 drives the active member 311 to slide, the active member 311 simultaneously drives one end of the two connecting members 312 to move along the motion trajectory of the active member 311, and the other ends of the two connecting members 312 respectively drive the two driven members 321 to move in the direction of approaching or moving away from each other, thereby changing the bending deformation of the traction rope 2.

[0097] In this embodiment, the motion trajectory of the active member 311 and the motion trajectory of the driven member 321 can also be perpendicular to each other. When the motion trajectory of the active member 311 and the motion trajectory of the driven member 321 are perpendicular to each other, the active member 311 can drive the two driven members 321 to move a greater distance during the movement. Therefore, when the length of the traction rope 2 remains unchanged, the movement stroke of the driving mechanism 5 is further reduced.

[0098] A plurality of support seats 12 are fixedly arranged on the cup cover base 1, and the plurality of support seats 12 are rectangular. The active member 311 abuts against the support seat 12, and the active member 311 slides and cooperates with the support seat 12. The support seat 12 not only supports the active member 311, but also guides the active member 311, thereby increasing the stability of the movement of the active member 311.

[0099] The connecting member 312 includes a connecting rod 3121, a first sleeve 3122 and a second sleeve 3123. One end of the connecting rod 3121 is fixedly connected to the first sleeve 3122, and the other end of the connecting rod 3121 is fixedly connected to the second sleeve 3123. The first sleeve 3122 is rotationally connected to the active member 311, and the second sleeve 3123 is rotationally connected to the driven member 321. The length direction of the connecting rod 3121 intersects with the motion trajectory of the first sleeve 3122. Since the length direction of the connecting rod 3121 intersects with the movement trajectory of the first sleeve 3122, the active member 311 drives the first sleeve 3122 to move during the movement, and at the same time makes the sleeve and the active member 311 rotate relative to each other. During the movement, the sleeve drives the connecting rod 3121 to move, and the connecting rod 3121 drives the second sleeve 3123 to move. Since the second sleeve 3123 is rotationally connected to the driven member 321, the second sleeve 3123 drives the driven member 321 to move during the movement.

[0100] The active member 311 includes an active block 3111, which is slidably matched with the cup cover base 1, and a linkage rack 42 is integrally formed on a side of the active block 3111 close to the linkage gear 41. An active rod 3112 is provided on the active block 3111, and a first sleeve 3122 is sleeved on the active rod 3112 and is rotatably connected to the active rod 3112. When the active member 311 moves, the active rod 3112 moves, and when the active rod 3112 moves, the first sleeve 3122 rotates around the active rod 3112, and when the first sleeve 3122 rotates, the connecting rod 3121 moves, and the other end of the connecting rod 3121 drives the driven member 321 to move.

[0101] The follower 321 includes a follower block 3211 and a follower rod 3212, and the follower block 3211 is slidably matched with the cup cover base 1. The follower rod 3212 is fixed on the follower block 3211, and the second sleeve 3123 is sleeved on the follower rod 3212 and is rotatably connected to the follower rod 3212. When the connecting rod 3121 moves, it drives the second sleeve 3123 to move. Since the second sleeve 3123 is sleeved on the follower rod 3212 and is rotatably connected to the follower rod 3212, when the second sleeve 3123 moves, it drives the follower rod 3212 to move. When the follower rod 3212 moves, it drives the follower block 3211 and the cup cover base 1 to slide relative to each other.

[0102] In this embodiment, the number of the stroke amplification components 32 can be one or more groups. When the number of the stroke amplification components 32 is multiple groups, the multiple groups of stroke amplification components 32 are arranged at intervals on the active member 311 of the linkage component 31, and the traction rope 2 sequentially passes through the driven members 321 of the multiple groups of stroke amplification components 32. Since the number of the stroke amplification components 32 is multiple groups, the multiple groups of stroke amplification components 32 are arranged at intervals on the active member 311, and the traction rope 2 sequentially passes through the driven members 321 of the multiple groups of stroke amplification components 32, the traction rope 2 can be bent and deformed multiple times by the driving mechanism 5 running through the multiple groups of stroke amplification components 32 at the same time, and the movement stroke of the driving mechanism 5 is further reduced.

[0103] A plurality of guide mechanisms 13 are provided on the cup cover base 1, and the number of the guide mechanisms 13 is the same as the number of the driven blocks 3211, and the driven blocks 3211 slide and cooperate with the guide mechanisms 13. The guide mechanism 13 has a guiding effect on the driven blocks 3211, thereby increasing the stability of the driven blocks 3211 sliding. In this embodiment, each guide mechanism 13 includes two guide blocks 131, and the two guide blocks 131 are fixed to the upper surface of the cup cover base 1, and each guide block 131 extends along the second direction, and a guide groove 132 is formed between the two guide blocks 131, and the driven member 321 slides and cooperates with the guide groove 132. It is worth noting that the sum of the thickness of the driven block 3211 and the diameter of the two traction ropes 2 is less than the width of the guide groove 132, thereby ensuring that the guide block 131 pulls the traction rope 2 to bend and deform, and the smoothness of the movement of the guide block 131 and the traction rope 2 in the guide groove 132 is increased.

[0104] Reference Figure 3 and Figure 4 This embodiment also discloses a cup cover, which includes not only the above-mentioned stroke amplification structure for the cup cover, but also a top cover 6, which covers the cup cover base 1, and the diameter of the top cover 6 is the same as the diameter of the cup cover base 1. The driving mechanism 5 is located on the top or side of the top cover 6, and the control mode of the driving mechanism 5 is push-pull or press or rotate, so a variety of control modes can be used to drive the traction rope to bend and deform.

[0105] Reference Figure 3 and Figure 4 In this embodiment, the top cover 6 is covered on the cup cover base 1, and the top cover 6 is rotatably connected to the cup cover base 1, and the stroke amplification mechanism 3 and the linkage mechanism 4 are both located in the top cover 6. The cup cover base 1 has a protective effect on the stroke amplification mechanism 3 and the linkage mechanism 4, which not only increases the cleanliness of the surface of the stroke amplification mechanism 3 and the linkage mechanism 4, but also prolongs the service life of the stroke amplification mechanism 3 and the linkage mechanism 4.

[0106] In this embodiment, the specific driving mechanism 5 includes an annular internal gear 51, which is fixed to the annular inner wall of the top cover 6, and the annular internal gear 51 is meshed with the linkage gear 41. The top cover 6 is rotated by applying an external force from the side or top of the top cover 6, thereby driving the stroke amplification mechanism 3 to operate.

[0107] Reference Figure 3 and Figure 4 The cup cover is provided with a positioning mechanism 7, which has a positioning effect on the stroke amplification mechanism 3 or the driving mechanism 5. In this embodiment, when the traction rope 2 drives the tea brewing component 9 to move to the position of the cup cover base 1 when it is bent and deformed, the positioning mechanism 7 has a fixing effect on the active component 311. Since the positioning mechanism 7 has a fixing effect on the active component 311 when the traction rope 2 drives the tea brewing component 9 to move to the position of the cup cover base 1 when it is bent and deformed, when the tea is brewed, the positioning mechanism 7 fixes the active component 311 so that the active component 311 will not move relative to the cup cover base 1, so that the traction rope 2 always maintains the maximum deformation, thereby ensuring that the tea brewing component 9 is located outside the tea.

[0108] The positioning mechanism 7 is magnetic positioning, ring positioning or snap positioning. The magnetic positioning is easy to use and does not require complicated operating procedures. It only needs to be placed on the object to be positioned and it will be automatically adsorbed without movement or shaking, and it is more stable. The ring positioning or snap positioning has the advantages of convenience, speed and diverse styles.

[0109] In this embodiment, the positioning mechanism 7 includes a first magnetic positioning member 71 and a second magnetic positioning member 72. A first mounting cylinder 3113 is fixedly provided on the upper surface of the active member 311, and the first magnetic positioning member 71 is fixed in the first mounting cylinder 3113. A second mounting cylinder 66 is fixedly provided on the inner side wall of the top cover 6, and the second magnetic positioning member 72 is fixed in the second mounting cylinder 66. There is a magnetic attraction between the first magnetic positioning member 71 and the second magnetic positioning member 72, and the first magnetic positioning member 71 and the second magnetic positioning member 72 can be magnets. When the traction rope 2 is bent and deformed, it drives the tea brewing component 9 to move to the position of the cup cover base 1, and the first magnetic positioning component 71 on the active component 311 has a magnetic attraction effect on the second magnetic positioning component 72 on the top cover 6. Therefore, when the tea is brewed, the second magnetic positioning component 72 has a magnetic attraction effect on the first magnetic positioning component 71, so that the active component 311 is magnetically attracted to the top cover 6, so that the active component 311 will not move relative to the top cover 6, so that the traction rope 2 always maintains the maximum deformation, thereby ensuring that the tea brewing component 9 is located outside the tea.

[0110] Reference Figure 1The present embodiment discloses a teacup, which comprises the cup cover and a cup body 8, wherein the cup cover is fitted on the cup body 8, and a tea brewing component 9 is located inside the cup body 8. Since the tea brewing component 9 is located inside the cup body 8, when a proper amount of boiling water is filled in the cup body 8, the travel amplification structure for the cup cover in the cup cover can not only move the tea brewing component 9 in the cup body 8 to the cup cover position, but also move the tea brewing component 9 from the cup cover position to the cup body 8, so that the cup body 8 does not need to be inverted during the tea brewing process, thereby improving the convenience of using the teacup.

[0111] The implementation principle of Example 1 is as follows: after the tea is brewed, the top cover 6 is rotated by applying an external force from the side or top of the top cover 6, and the linkage gear 41 rotates. Since the linkage gear 41 and the linkage rack 42 are meshed with each other, the linkage gear 41 drives the linkage rack 42 to slide when rotating, and the linkage rack 42 drives the stroke amplification mechanism 3 to operate when sliding. The stroke amplification mechanism 3 causes the traction rope 2 to bend and deform multiple times during operation, and the traction rope 2 drives the tea brewing part 9 to move toward the direction close to the cup cover base 1 when bending and deforming; since the movement stroke of the driving mechanism 5 is smaller than the movement stroke of the tea brewing part 9, the driving mechanism 5 can not only move the tea brewing part 9 from the cup body 8 to the position of the cup cover, thereby realizing tea and water separation; at the same time, the driving mechanism 5 can also move the tea brewing part 9 from the cup cover to the cup body 8, thereby realizing fast tea brewing; compared with the background technology, during the process of brewing tea, the user does not need to invert the teacup twice, thereby improving the convenience of using the teacup.

[0112] Example 2

[0113] Reference Figure 5 and Figure 6 , the difference between this embodiment and embodiment 1 is that: in this embodiment, the top cover 6 is covered on the cup cover base 1, and the top cover 6 is fixedly connected to the cup cover base 1. The specific driving mechanism 5 includes a rotating grip 52, and the rotating grip 52 is fixedly connected to the linkage gear 41. A through rotating hole 61 is provided on the upper surface of the top cover 6, and the rotating grip 52 passes through the rotating hole 61. The rotating grip 52 is rotatably connected to the top cover 6, and the top end of the rotating grip 52 protrudes from the top cover 6. The rotating grip 52 is rotated by applying an external force from the top of the top cover 6, thereby driving the stroke amplification mechanism 3 to operate.

[0114] The implementation principle of Example 3 is as follows: after the tea is brewed, the rotating grip 52 is rotated by applying an external force from the top of the top cover 6, and the rotating grip 52 drives the linkage gear 41 to rotate. The linkage gear 41 drives the linkage rack 42 to slide when rotating, and the linkage rack 42 drives the active member 311 to slide along the length direction of the slide groove 62 when sliding. The active member 311 drives the stroke amplification mechanism 3 to operate when sliding, and the stroke amplification mechanism 3 causes the traction rope 2 to bend and deform multiple times when running, thereby driving the tea bin to rise and realizing the separation of tea and water; when it is necessary to brew tea again, the rotating grip 52 is rotated in the opposite direction, thereby driving the linkage gear 41 to rotate in the opposite direction, and the linkage gear 41 drives the linkage rack 42 to slide in the opposite direction, thereby reducing the bending deformation of the traction rope 2 and realizing re-brewing of tea.

[0115] Example 3

[0116] Reference Figure 7 and Figure 8 The difference between this embodiment and the first embodiment is that: in this embodiment, two support blocks 17 are fixedly provided on the upper surface of the cup cover base 1, and the two support blocks 17 are parallel to each other. A rotation groove 18 is provided on the side where the tops of the two support blocks 17 are close to each other. The axis of the linkage gear 41 extends along the second direction, and the second rotation shaft 43 (refer to Fig. 9 ), the two second rotating shafts 43 are respectively located in the two rotating grooves 18, the two second rotating shafts 43 are respectively rotatably connected to the two second supporting blocks 17, and the linkage gear 41 and the linkage rack 42 are meshed with each other.

[0117] In this embodiment, the top cover 6 is covered on the cup cover base 1, and the top cover 6 is fixedly connected to the cup cover base 1. The specific driving mechanism 5 includes a push-pull seat 53 and a driving rack 54. The upper surface of the top cover 6 is provided with a through slide 62, and the slide 62 extends along the first direction. Both ends of the slide 62 are closed. The push-pull seat 53 passes through the slide 62, and the push-pull seat 53 and the slide 62 are slidably matched, and the top of the push-pull seat 53 protrudes from the surface of the top cover 6. The driving rack 54 is fixed to the lower surface of the push-pull seat 53, and the driving rack 54 is meshed with the linkage gear 41.

[0118] The implementation principle of Example 4 is as follows: when the tea is brewed, the push-pull seat 53 is pushed to make the push-pull seat 53 slide along the length direction of the slide groove 62, and the push-pull seat 53 drives the driving rack 54 to slide along the length direction of the slide groove 62; because the driving rack 54 and the linkage gear 41 are meshed with each other, the driving rack 54 drives the linkage gear 41 to rotate when sliding, and the linkage gear 41 drives the linkage rack 42 to slide when rotating, and the linkage rack 42 drives the active member 311 to slide along the length direction of the slide groove 62 when sliding, and the active member 311 drives the stroke amplification mechanism 3 to operate when sliding, and the stroke amplification mechanism 3 causes the traction rope 2 to bend and deform multiple times when operating, thereby driving the tea bin to rise and realizing tea and water separation; when it is necessary to brew tea again, the push-pull seat 53 is pushed in the opposite direction, and the push-pull seat 53 drives the driving rack 54 to slide in the opposite direction, thereby driving the linkage gear 41 to rotate in the opposite direction, and the linkage gear 41 drives the linkage rack 42 to slide in the opposite direction, thereby reducing the bending deformation of the traction rope 2, and realizing re-brewing of tea.

[0119] Example 4

[0120] Reference Fig.10 and Fig.11 The difference between this embodiment and the embodiment 3 is that the driving mechanism 5 further includes a push-pull block 55, which extends along the first direction, and one end of which is fixedly connected to the push-pull seat 53. In this embodiment, the push-pull block 55 can be located not only on the side of the push-pull seat 53 close to the through hole 11, but also on the side of the push-pull seat 53 away from the through hole 11. The push-pull block 55 is pushed or pulled by applying an external force from the side of the top cover 6, thereby driving the stroke amplification mechanism 3 to operate.

[0121] The side wall of the top cover 6 is also provided with a first guide hole 64, and the other end of the push-pull block 55 passes through the first guide hole 64, and the push-pull block 55 is slidably matched with the cup cover base 1. Not only can the tea brewing and tea water separation be achieved by pushing the push-pull seat 53, but also the push-pull seat 53 can be driven to slide back and forth by pushing the push-pull block 55, which further increases the convenience of tea brewing.

[0122] Example 5

[0123] Reference Fig.12 and Fig.13The difference between this embodiment and the embodiment 4 is that the driving mechanism 5 further includes a pressing seat 56, and the top cover 6 is further provided with a lifting groove 63 which is interconnected with the slide groove 62. The pressing seat 56 is slidably matched with the lifting groove 63, and the pressing seat 56 can only be lifted and lowered in the lifting groove 63. The pressing seat 56 moves toward or away from the push-pull seat 53 during the lifting process. The push-pull seat 53 is pushed by applying an external force from the top of the top cover 6, thereby driving the stroke amplification mechanism 3 to operate. The pressing seat 56 is provided with a first inclined surface 561, and the push-pull seat 53 is provided with a second inclined surface 531, and the first inclined surface 561 abuts against the second inclined surface 531. Since the pressing seat 56 and the lifting slot 63 are slidably matched, the pressing seat 56 is pressed by external force to move toward the push-pull seat 53. Since the pressing seat 56 is provided with a first inclined surface 561 and the push-pull seat 53 is provided with a second inclined surface 531, the first inclined surface 561 abuts against the second inclined surface 531. The pressing seat 56 is pressed by applying external force from the top of the top cover 6, thereby driving the stroke amplification mechanism 3 to operate.

[0124] When the pressing seat 56 is pressed, the pressing seat 56 drives the push-pull seat 53 to slide along the length direction of the slide groove 62, and the push-pull seat 53 drives the driving rack 54 to slide along the length direction of the slide groove 62. The driving rack 54 drives the linkage gear 41 to rotate when sliding, and the linkage gear 41 drives the linkage rack 42 to slide when rotating. The linkage rack 42 drives the active part 311 to slide along the length direction of the slide groove 62 when sliding. The active part 311 drives the stroke amplification mechanism 3 to operate when sliding. When the stroke amplification mechanism 3 is running, the traction rope 2 is bent and deformed multiple times, thereby driving the tea bin to rise and realizing the separation of tea and water.

[0125] In this embodiment, the driving mechanism 5 further includes a pulling member 57, one end of which is fixedly connected to the active member 311; a second guide hole 65 is provided on the top cover 6, and the other end of the pulling member 57 passes through the second guide hole 65, and the pulling member 57 is slidably matched with the top cover 6. The pulling member 57 is pulled by applying an external force from the side of the top cover 6, thereby driving the stroke amplification mechanism 3 to operate.

[0126] When the tea is brewed, in the process of pressing the pressing seat 56, not only can the tea and water be separated; at the same time, since one end of the pulling member 57 is fixedly connected to the active member 311, and the other end of the pulling member 57 passes through the second guide hole 65, the active member 311 drives the pulling member 57 to slide along the length direction of the slide groove 62 during the sliding process, and the guide hole guides the pulling member 57, thereby increasing the sliding stability of the pulling member 57; when the tea is brewed, by pulling the pulling member 57 in opposite directions, the pulling member 57 drives the active member 311 to slide in opposite directions, and the active member 311 restores the stroke amplification mechanism 3 to its initial position when sliding, thereby reducing the bending deformation of the traction rope 2 and realizing re-brewing of tea.

[0127] Example 6

[0128] Reference Fig.14 In this embodiment, a first magnetic component 21 is fixedly provided at one end of the traction rope 2 close to the tea brewing component 9, and a second magnetic component 91 is fixedly provided inside the tea brewing component 9. The first magnetic component 21 and the second magnetic component 91 are connected by magnetic attraction, sleeve connection or clamping, and the force between the first magnetic component 21 and the second magnetic component 91 is greater than the sum of the gravity exerted on the tea leaves and the tea brewing component 9. The magnetic attraction between the first magnetic component 21 and the second magnetic component 91 can not only fix the tea brewing component 9 to the free end of the traction rope 2, but also increase the convenience of the user to install and remove the tea brewing component 9.

[0129] A sealed channel 19 is fixedly provided on the side of the cup cover base 1 facing away from the upper cover, the top of the sealed channel 19 is interconnected with the through hole 11, the bottom of the sealed channel 19 is sealed, and the length of the sealed channel 19 is less than the height of the cup body 8. The first magnetic component 21 is movably provided in the sealed channel 19, and the tea brewing component 9 is movably provided outside the sealed channel 19. Since the first magnetic component 21 is movably provided in the sealed channel 19, the sealed channel 19 has a barrier effect on the tea, thereby ensuring that the traction rope 2 and the first magnetic component 21 will not be soaked by the tea; at the same time, since the tea brewing component 9 is movably provided outside the sealed channel 19, it is convenient to make tea, and at the same time, the magnetic attraction between the first magnetic component 21 and the second magnetic component 91 facilitates the movement of the tea brewing component 9 in the cup body 8.

[0130] Example 7

[0131] Reference Fig.10 and Fig.15 The difference between this embodiment and embodiment 4 is that: the top cover 6 is further provided with a reset mechanism 10, which is used to drive the stroke amplification mechanism 3 and / or the driving mechanism 5 to reset (combined with Figure 3 ). After the stroke amplification mechanism 3 or the driving mechanism 5 is running, the reset mechanism 10 can reset the stroke amplification mechanism 3 or the driving mechanism 5.

[0132] Reference Figure 3 and Fig.15 In this embodiment, the specific reset mechanism 10 is a reset spring, one end of the reset spring abuts against the top cover 6 or the cup cover base, and the other end of the reset spring abuts against the stroke amplification mechanism 3 and / or the driving mechanism 5. When the stroke amplification mechanism 3 and / or the driving mechanism 5 drive the traction belt to be reeled, the stroke amplification mechanism 3 and / or the driving mechanism 5 squeeze the reset spring, and the reset spring stores elastic potential energy. When the reset spring releases the elastic force, the stroke amplification mechanism 3 and / or the driving mechanism 5 returns to the initial position.

[0133] Reference Fig.15Specifically, a limiting member 67 is installed at one end of the slide slot 62, and a limiting slot 68 is provided on the side of the limiting member 67 close to the push-pull seat 53, and a limiting column 58 is fixedly provided on the side of the push-pull seat 53 close to the limiting member 67. The return spring is located in the slide slot 62, and one end of the return spring close to the limiting member 67 is connected to the limiting slot 68, and the other end of the return spring is sleeved on the limiting column 58. The limiting slot 68 and the limiting column 58 respectively have a limiting effect on both ends of the spring. When the push-pull seat 53 moves toward the direction close to the limiting member 67, the push-pull seat 53 and the limiting member 67 squeeze the return spring, so that the return spring undergoes elastic deformation and stores elastic potential energy; when the positioning effect of the positioning mechanism 7 on the push-pull seat 53 is released and the external force on the push-pull seat 53 is released, the push-pull seat 53 is reset under the elastic force of the return spring.

[0134] The above are all preferred embodiments of the present application, and the protection scope of the present application is not limited thereto. Therefore, any equivalent changes made according to the structure, shape, and principle of the present application should be included in the protection scope of the present application.
