Description

Technical Field

[0001] The present invention relates to the technical field of electronic equipment accessories, and in particular to a flexible screen hinge structure. Background Art

[0002] Flexible screen refers to flexible OLED. The successful mass production of flexible screens is not only a major boon to the manufacturing of a new generation of high-end smartphones, but also has a profound impact on the application of wearable devices due to its low power consumption and bendable characteristics. In the future, flexible screens will be widely used with the continuous penetration of personal smart terminals. Flexible screen mobile phones refer to mobile phones with bendable and flexible screens. Because of their resemblance to a awn scroll, they are also called awn scroll phones. Compared with traditional screens, flexible screens have obvious advantages. Not only are they thinner and lighter in size, but their power consumption is also lower than the original devices, which helps to improve the battery life of the device. At the same time, based on their bendable and flexible characteristics, their durability is also much higher than previous screens, reducing the probability of accidental damage to the device.

[0003] The opening or closing between the screen and the device body is generally achieved by setting a hinge, and the torque of the hinge is needed to support the weight of the screen so that the screen remains at a certain rotation angle relative to the body. To achieve the folding function of the flexible screen, in addition to the screen itself, the connection component for folding, that is, the design of the connection shaft at the bend, is also the biggest technical challenge. Considering the particularity of the flexible screen, the traditional hinge cannot meet its functional requirements, and a special flexible screen hinge is needed to assist in the realization.

[0004] There are many flexible screen hinges in the prior art, such as the application number 202321380214.7, the authorization announcement number CN219697689U, and the name of a hinge for unfolding a water drop-shaped screen. The above patent discloses a hinge for unfolding a water drop-shaped screen, including a support, both ends of the support are fixedly connected to a bracket, the bracket is movably connected to a rotating component inside, and the rotating component is fixedly connected to a folding component at the outer wall of the bracket; the folding component is movably connected to a sliding component inside, and the sliding component is movably connected to the end of the bracket with a rotating component, and the folding component is movably connected to the outer wall of the sliding component. The door panel is movably connected. In the above patent, the rotating component is driven to rotate the rotating component and the folding component at the same time, and the door panel is driven to rotate by the folding component and the sliding component, and the mobile phone screen is folded by rotating and flipping the door panel.

[0005] Another example is a Chinese patent with application number 202410072827.7, authorization announcement number CN117847079B, and name "A folding hinge shaft and assembly mechanism". The above patent discloses a folding hinge shaft and assembly mechanism, including a plug-in housing, including a first fixed element, a first rotating shaft, a second rotating shaft, a locking element, a first hinge element, a second hinge element and a second fixed element. The assembly mechanism includes an assembly jig, a positioning assembly and a clamping assembly.

[0006] It is well known that the rotating shaft of the flexible screen is connected to the flexible screen through a hinge. And the rotating shaft on the flexible screen usually needs to use a locking part to lock the rotating shaft at a predetermined angle to achieve the angle adjustment of the flexible screen, or to ensure that the flexible screen will not be easily opened in the expanded or closed state. And it is well known that the locking part in the rotating shaft is generally divided into a locking block that is slidably connected to the inside of the rotating shaft through multiple springs and a locking block installed on the hinge. The elastic force of the spring drives the two locking blocks to engage to achieve the locking of the hinge. Since the spring is made of metal, after long-term use, the spring elasticity will be weakened due to metal fatigue, and it is easy to have insufficient elasticity.

[0007] When the spring is weakened, although the rotating shaft used in the flexible screen in the prior art can facilitate the replacement of the spring, in actual use, when one of the springs inside the rotating shaft is weakened, the other springs can barely make the two locking blocks engage, so it is impossible to remind the user that the spring inside the rotating shaft has weakened. At this moment, the user cannot know in time that the spring inside the rotating shaft has weakened. When one of the springs is weakened, the pressure on the other springs will increase, so that the life of the other springs will also be shortened. When the other springs are weakened again, there is not enough elastic force to drive the two locking blocks to engage. At this moment, the flexible screen cannot adjust the angle, and even the flexible screen can be easily unfolded in the closed state, which seriously affects the use of the user. When the spring is weakened, the rotating shaft in the prior art cannot adjust the elastic force of the spring so that the two locking blocks can engage, and cannot meet the emergency needs of the user.

[0008] It can be seen from this that how to promptly remind the user when the elasticity of the spring inside the hinge weakens and how to adjust the elastic force when the spring is released so that the flexible screen can be used normally is a technical problem that needs to be solved urgently. Summary of the invention

[0009] The purpose of the present invention is to provide a flexible screen hinge structure to solve the problems raised in the above background technology.

[0010] To achieve the above-mentioned purpose, the present invention provides the following technical solutions: a flexible screen shaft structure, comprising a shell and a mounting portion arranged inside the shell, a first hinge and a second hinge are respectively installed on both sides of the mounting portion, the first hinge and the second hinge are transmission-connected by a gear connector, and the shell is provided with a locking portion for positioning the gear connector; the locking portion comprises a sliding seat slidably connected to the inside of the shell through a slider, a plurality of groups of second locking blocks are installed on the sliding seat, and a plurality of groups of first locking blocks respectively matched with the second locking blocks are installed on the gear connector, and a plurality of groups of clamping springs are arranged between the shell and the sliding seat; a clamping portion for clamping the slider is arranged inside the shell, and when the elastic force of the clamping spring is less than the elastic force of the clamping portion, the clamping portion fixes the slider; and an adjusting mechanism for adjusting the elastic force of the clamping spring when it is released is arranged inside the shell, and when the clamping portion fixes the slider, the adjusting mechanism adjusts the elastic force released by the clamping spring after overcoming the elastic force of the clamping portion, so that the first locking block is again engaged with the second locking block.

[0011] Furthermore, the adjustment mechanism includes an adjustment seat slidably connected to the inside of the shell, the slider and the adjustment seat are intermittently connected through a connecting piece, and a driving piece is also provided on the shell. After the driving piece drives the connecting piece to connect with the adjustment seat, the adjustment seat slides inside the shell to adjust the elastic force released by the clamping spring.

[0012] Furthermore, a sliding groove is provided on the shell, and the sliding seat is slidably connected to the inside of the shell by sliding the slider in the sliding groove; the clamping part includes a clamping plate slidably connected to the side wall of the shell, a positioning block is fixedly connected to the clamping plate, and a clamping spring is arranged between the positioning block and the shell, and the elastic force of the clamping spring drives the clamping plate to contact the slider.

[0013] Furthermore, the driving member includes a driving block slidably connected to the inside of the shell, and a rotating rod is rotatably connected to the shell, and a driving gear is provided on the rotating rod, and a power rack fixedly connected to the driving block is slidably connected to the inside of the shell, and the driving gear is meshed with the power rack.

[0014] Furthermore, the connecting member includes a connecting plate installed on the bottom of the slider, and a buffer portion is arranged between the connecting plate and the slider, a connecting frame is fixedly connected to the connecting plate, and a snap-in plate is slidably connected to the connecting frame through a positioning member, and the driving block abuts and cooperates with the snap-in plate; a power frame is arranged on the bottom of the adjusting seat through a force-bearing plate; and a driving groove adapted to the driving block is opened on one side of the connecting frame, and when the driving block slides inside the driving groove, the abutting plate is driven to slide upward so that the snap-in plate is snapped into the power frame.

[0015] Furthermore, a locking member is provided between the shell and the power frame. When the adjustment seat slides inside the shell to adjust the elastic force released by the clamping spring, the locking member fixes the adjusted adjustment seat. The locking member includes a locking plate slidably connected to the inside of the shell, a locking spring is provided between the locking plate and the shell, and a locking groove is provided on the power frame. The elastic force of the locking spring drives the locking block to be clamped in the locking groove.

[0016] Furthermore, an unlocking portion is provided between the power frame and the clamping plate. When the adjustment seat slides inside the shell to adjust the elastic force released by the clamping spring, the state of the clamping plate is adjusted by the unlocking portion so that the clamping plate is away from the slider.

[0017] Furthermore, the unlocking part includes an unlocking rod fixedly connected to the power frame, an unlocking block is fixedly connected to the unlocking rod, and the positioning block is provided with an unlocking groove adapted to the unlocking block, and the unlocking block intermittently abuts against the unlocking groove.

[0018] Furthermore, a driving disk is installed on the end of the rotating rod, and a limiting portion is provided between the driving disk and the housing.

[0019] Furthermore, a reset member is provided between the driving block and the shell, and the reset member includes a reset plate fixedly connected to the bottom of the shell, and a reset spring is provided between the reset plate and the shell, and the elastic force of the reset spring drives the driving block away from the connection frame.

[0020] Compared with the prior art, the present invention has the following beneficial effects:

[0021] 1. When the clamping spring has insufficient elasticity due to long-term use or other circumstances (that is, the elastic force of the clamping spring is less than the elastic force of the clamping part), the clamping part will fix the slider at this moment, that is, the sliding seat cannot slide at this moment, that is, the first locking block cannot be engaged with the second locking block, that is, the gear connector cannot be locked at this moment, and the damping force of the flexible screen will disappear at this moment. The user can easily know that the clamping spring has insufficient elasticity without having to use specific equipment for detection, thereby avoiding the insufficient elasticity of the clamping spring, thereby avoiding the situation that affects the normal use of the user.

[0022] 2. After the clamping force slider is clamped, the adjustment mechanism is used to adjust the elastic force released by the clamping spring to keep the elastic force on the sliding seat constant, so that the first locking block can be engaged with the second locking block again. When the first locking block is engaged with the second locking block again, the state of the gear connector can be fixed again, and then the state of the flexible screen can be limited to meet the user's emergency needs and leave the user with sufficient time for inspection and maintenance, avoiding the situation where the flexible screen cannot be used normally due to insufficient elasticity of the clamping spring. It is suitable for wide promotion and use.

[0023] 3. Through the cooperation between the driving part, the connecting part, etc., when the clamping spring can normally drive the sliding seat to reset, the driving part will not be connected to the connecting part at this moment. Even if the driving part is driven to move at this moment, the state of the adjustment seat cannot be adjusted, thereby achieving the effect of preventing accidental touch. Only when the clamping spring cannot drive the sliding seat to reset, the connecting part is located directly below the adjustment seat. After that, the driving part drives the connecting part to connect with the adjustment seat, which drives the adjustment seat to slide inside the shell. Only at this moment can the elastic force of the clamping spring be adjusted when it is released, thereby further improving the practicality of the rotating shaft. BRIEF DESCRIPTION OF THE DRAWINGS

DETAILED DESCRIPTION

[0044] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0045] See also Figure 1-Figure 18 The present invention provides a technical solution: a flexible screen hinge structure, including a shell 1 and a mounting portion 2 arranged inside the shell 1. The mounting portion 2 is provided to facilitate the installation and use of the first hinge 3 and the second hinge 4 in the later stage. The first hinge 3 and the second hinge 4 are respectively installed on both sides of the mounting portion 2. Therefore, when the hinge structure is needed, the first hinge 3 and the second hinge 4 can be installed on a predetermined screen, and the flexible screen can be folded at this moment. The first hinge 3 and the second hinge 4 are connected by a gear connector 5. Specifically, the gear connector 5 includes two bases installed on the mounting portion 2. The two bases are rotatably connected with connecting gears 51 through a connecting shaft 52. The four connecting gears 51 are meshed in sequence, and the two connecting gears 51 located on the outermost side of the mounting seat 53 are respectively connected to the first hinge 3 and the second hinge 4, so as to facilitate the use of the hinge structure.

[0046] The housing 1 is provided with a locking portion 6 for positioning the gear connector 5. By providing the locking portion 6, the state of the connecting gear 51 can be locked, and then the first hinge 3 and the second hinge 4 on both sides of the gear connector 5 can be locked and fixed, so as to meet the need of the flexible screen to be in a static state after folding, and the effect is better. The locking portion 6 includes a sliding seat 63 slidably connected to the inside of the housing 1 through a slider 10, and a plurality of groups of second locking blocks 62 are installed on the sliding seat 63. Specifically, there are four second locking blocks 62, and a plurality of groups of first locking blocks 61 respectively matched with the second locking blocks 62 are installed on the gear connector 5. There are also four first locking blocks 61, and the first locking blocks 61 correspond to the second locking blocks 62 one by one. Specifically, a first locking surface 611 is provided on the first locking block 61, and a plurality of first locking surfaces 611 are distributed in a circumferential array on the first locking block 61, wherein a second locking surface 621 is also provided on the second locking block 62, and the installation method of the second locking surface 621 is consistent with the installation method of the first locking surface 611. Specifically, the first locking surface 611 and the second locking surface 621 are both wedge-shaped, and when the first locking block 61 and the second locking block 62 are engaged, when the connecting gear 51 rotates at this moment, a force is generated to drive the first locking block 61 and the second locking block 62 to move away from each other. Since the first locking block 61 is arranged on the mounting portion 2 through the mounting seat 53, when the first locking block 61 and the second locking block 62 rotate, the second locking block 62 is driven to slide to the side away from the first locking block 61. In addition, multiple groups of clamping springs 8 are arranged between the shell 1 and the sliding seat 63. The elastic force of the clamping springs 8 drives the first locking block 61 to engage with the second locking block 62. More specifically, when the first locking block 61 and the second locking block 62 rotate, the second locking block 62 will be driven to slide to the side away from the first locking block 61. When the first locking surface 611 tends to engage with the second locking surface 621 again, the elastic force of the clamping spring 8 will drive the second locking block 62 to engage with the first locking block 61 again, fixing the state of the connecting gear 51, and then fixing the first hinge 3 and the second hinge 4, thereby meeting the need for the flexible screen to be in a static state after folding, avoiding the flexible screen from unfolding without external force, and the effect is better.

[0047] The housing 1 is provided with a clamping portion 11 for clamping the slider 10. Specifically, there can be two clamping portions 11, which are respectively provided on both sides of the housing 1 for better effect. Specifically, the structures and working principles of the two clamping portions 11 are consistent, and only one of them is described below. When the elastic force of the clamping spring 8 is in normal use, the elastic force of the clamping spring 8 can easily drive the sliding seat 63 to slide, so that the slider 10 can easily drive the slider 10 to overcome the friction force generated by the clamping portion 11 and the slider 10, and then slide out of the clamping portion 11, and normally drive the first locking block 61 to engage with the second locking block 62. At this moment, when the clamping spring 8 has insufficient elasticity due to long-term use or other circumstances (that is, the elastic force of the clamping spring 8 is less than the elastic force of the clamping part 11), the clamping part 11 fixes the slider 10 at this moment, that is, the clamping spring 8 cannot drive the sliding seat 63 to reset, that is, the first locking block 61 cannot be engaged with the second locking block 62, that is, the gear connector 5 cannot be locked at this moment, and the damping force of the flexible screen will disappear. The user can easily know that the clamping spring 8 has insufficient elasticity without the need for specific equipment detection, so as to avoid the problem of insufficient elasticity of the clamping spring 8, which can prevent the flexible screen from being easily unfolded in the closed state after the elasticity of the clamping spring 8 is insufficient. Therefore, it can avoid the situation that seriously affects the user's use, improve the practicality of the rotating shaft, and achieve better use effect.

[0048] The housing 1 is provided with an adjustment mechanism for adjusting the elastic force of the abutting spring 8 when it is released, so as to keep the elastic force on the sliding seat 63 constant. When the clamping portion 11 fixes the slider 10, the adjustment mechanism overcomes the elastic force of the clamping portion 11 and adjusts the elastic force released by the abutting spring 8, so that the first locking block 61 is again engaged with the second locking block 62. Therefore, during use, when the elastic force of the abutting spring 8 is insufficient within a predetermined length and cannot drive the slider 10 to separate from the clamping portion 11, the travel of the abutting spring 8 is adjusted by using the adjustment mechanism, so that the abutting spring 8 can overcome the elastic force of the clamping portion 11 and drive the slider 10 to slide out of the clamping portion 11, so that the first locking block 61 can be engaged with the second locking block 62 again. When the first locking block 61 is engaged with the second locking block 62 again, the state of the gear connector 5 can be fixed again, so that the state of the flexible screen can be limited, which greatly meets the work needs. For this reason, when the elasticity of the pressing spring 8 is insufficient, the damping force of the flexible screen will disappear. The user can easily know that the pressing spring 8 is insufficient in elasticity without the need for specific equipment detection, so as to avoid the flexible screen being easily unfolded in the closed state after the pressing spring 8 is insufficient in elasticity, thereby avoiding the situation that seriously affects the user's use. Then, the adjustment mechanism is used to adjust the elastic force released by the pressing spring 8 to keep the elastic force on the sliding seat 63 constant, so that the first locking block 61 can be engaged with the second locking block 62 again. When the first locking block 61 is engaged with the second locking block 62 again, the state of the gear connector 5 can be fixed again, and then the state of the flexible screen can be limited, so as to meet the user's emergency needs and leave the user with sufficient time to go to a professional place for inspection and maintenance, so as to avoid the situation that the flexible screen cannot be used normally when the elasticity of the pressing spring 8 is insufficient, and it is suitable for wide promotion and use.

[0049] In the embodiment provided by the present invention, the adjustment mechanism includes an adjustment seat 7 slidably connected inside the housing 1. Specifically, a clamping spring 8 is arranged between the adjustment seat 7 and the sliding seat 63, and a limited axis is arranged between the adjustment block and the sliding seat 63 to improve the stability of the adjustment seat 7 and the sliding seat 63 when sliding, so as to achieve better use effect. The slider 10 is intermittently connected with the adjustment seat 7 through a connecting piece 14, and a driving piece 13 is also arranged on the housing 1. After the driving piece 13 drives the connecting piece 14 to connect with the adjustment seat 7, the adjustment seat 7 slides inside the housing 1 to adjust the elastic force released by the clamping spring 8. That is, when the first locking block 61 and the second locking block 62 rotate, the second locking block 62 will be driven to drive the sliding seat 63 to slide inside the housing 1. At this moment, during the sliding stroke of the sliding seat 63, the connecting piece 14 will be driven by the slider 10 to slide toward the side close to the adjustment seat 7 to keep the elastic force on the sliding seat 63 constant, so as to ensure that the first locking block 61 can be smoothly engaged with the second locking block 62. When the elasticity of the clamping spring 8 is insufficient (that is, the elastic force of the clamping spring 8 is less than the elastic force of the clamping part 11), the clamping part 11 fixes the slider 10 at this moment, that is, the clamping spring 8 cannot drive the sliding seat 63 to reset at this moment. At this moment, the connecting member 14 is located directly below the adjusting seat 7. After that, the connecting member 14 is driven to connect with the adjusting seat 7 by the driving member 13, and the adjusting seat 7 is driven to slide inside the shell 1 to adjust the stroke of the clamping spring 8, thereby increasing the elasticity of the clamping spring 8, and enabling the first locking block 61 to be engaged with the second locking block 62 again, so that the state of the gear connector 5 can be fixed again, and then the state of the flexible screen can be limited to meet the user's emergency needs. When the clamping spring 8 can normally drive the sliding seat 63 to reset, the driving member 13 will not be connected to the connecting member 14 at this moment. Even if the driving member 13 is driven to move at this moment, the state of the adjusting seat 7 cannot be adjusted, thereby achieving the effect of preventing accidental touch. Only when the clamping spring 8 cannot drive the sliding seat 63 to reset, the connecting member 14 is located directly below the adjusting seat 7 at this moment. After that, the connecting member 14 is driven by the driving member 13 to connect with the adjusting seat 7, which will drive the adjusting seat 7 to slide inside the shell 1. Only at this moment can the elastic force of the clamping spring 8 be adjusted when it is released to keep the elastic force on the sliding seat 63 constant, thereby further improving the practicality of the rotating shaft.

[0050] In the embodiment provided by the present invention, a slide groove 9 is provided on the housing 1, and the sliding seat 63 is slidably connected inside the housing 1 by sliding the slider 10 inside the slide groove 9. In the original state, the adjustment seat 7 is located on one side of the housing 1, and at this moment, the force plate 12 on the bottom of the adjustment seat 7 is also located on one side of the slide groove 9, and the pressing spring 8 is arranged between the sliding seat 63 and the adjustment seat 7 to meet the clamping needs of the first locking block 61 and the second locking block 62. The clamping part 11 includes a clamping plate 111 slidably connected to the side wall of the housing 1, a positioning block 113 is fixedly connected to the clamping plate 111, and a connecting block 112 is arranged between the positioning block 113 and the clamping plate 111, so as to ensure the stability of the clamping plate 111 during installation. In addition, anti-slip stripes are provided on the upper surface of the clamping plate 111, so as to further increase the friction between the clamping plate 111 and the slider 10, and the effect is better. A clamping spring 114 is provided between the positioning block 113 and the housing 1, and the elastic force of the clamping spring 114 drives the clamping plate 111 to contact the slider 10. Specifically, when the elastic force of the multiple sets of clamping springs 8 is not reduced, the elastic force of the multiple sets of clamping springs 8 is greater than the elastic force of the clamping spring 114, and thus the slider 10 can be driven to slide out of the clamping portion 11. When the spring elastic force inside the clamping spring 8 is weakened, the elastic force of the clamping spring 8 is less than the elastic force of the clamping spring 114, and the clamping spring 8 cannot drive the slider 10 to slide out of the clamping portion 11, that is, the gear connector 5 cannot be locked at this moment, and the damping force of the flexible screen will disappear at this moment. The user can easily know that the clamping spring 8 has insufficient elasticity without the need for specific equipment detection, thereby meeting work needs.

[0051] In the embodiment provided by the present invention, the driving member 13 includes a driving block 135 slidably connected to the inside of the housing 1, and a rotating rod 131 is rotatably connected to the housing 1, and a driving gear 133 is provided on the rotating rod 131, and a power rack 134 fixedly connected to the driving block 135 is slidably connected to the inside of the housing 1, and the driving gear 133 is meshed with the power rack 134. Specifically, during use, the driving gear 133 is driven to rotate by the rotation of the rotating rod 131, and the driving block 135 can be driven to slide through the power rack 134.

[0052] In the embodiment provided by the present invention, the connecting member 14 includes a connecting plate 141 installed on the bottom of the slider 10, wherein a connecting frame 142 is fixedly connected to the connecting plate 141, and a clamping plate 144 is slidably connected to the connecting frame 142 through a positioning member 146, and the driving block 135 is in abutment with the clamping plate 144. Specifically, a vertical groove 145 is provided on the connecting frame 142, and the clamping plate 144 is slidably connected to the connecting frame 142 through the vertical groove 145. Specifically, the positioning member 146 includes a connecting plate fixedly connected to the connecting plate 141, and a positioning spring is provided between the connecting plate and the connecting frame 142, and the elastic force of the positioning spring drives the clamping plate 144 away from the power frame 147. A power frame 147 is provided on the bottom of the adjustment seat 7 through the force plate 12; and a driving groove 143 adapted to the driving block 135 is provided on one side of the connection frame 142. When the driving block 135 slides inside the driving groove 143, the contact plate is driven to slide upward, so that the clamping plate 144 is clamped into the power frame 147. Therefore, during use, when the abutting spring 8 can normally drive the sliding seat 63 to reset, the driving member 13 will not be connected to the connection member 14 at this moment. Even if the driving member 13 is driven to move at this moment, the state of the adjustment seat 7 cannot be adjusted, so that the effect of preventing accidental touch can be achieved. Only when the abutting spring 8 cannot drive the sliding seat 63 to reset, the connection member 14 is located directly below the adjustment seat 7 at this moment. The driving gear 133 is driven to rotate by rotating the rotating rod 131, and then the driving block 135 can be driven to slide through the power rack 134. When the driving block 135 slides inside the driving groove 143, the clamping plate 144 will be driven to overcome the positioning piece 146 and then drive the clamping plate 144 to slide upward, so that the clamping plate 144 enters the power frame 147. When the clamping plate 144 is clamped with the power frame 147, the connecting frame 142 is driven to slide inside the shell 1 through the driving block 135, and then the connecting frame 142 can be driven to slide inside the shell 1 through the clamping plate 144, and the stroke of the clamping spring 8 can be adjusted to achieve the stroke for adjusting the elastic force released by the clamping spring 8 to meet working needs.

[0053] In another embodiment provided by the present invention, a buffer portion is provided between the connecting plate 141 and the slider 10. Specifically, the buffer portion includes a buffer block 191 fixedly connected to the bottom of the slider 10, and a buffer groove 192 is provided on the connecting plate 141. The buffer block 191 is slidably connected in the buffer groove 192, and a buffer spring 193 is provided between the buffer block 191 and the buffer groove 192. When the first locking block 61 is engaged with the second locking block 62 again, the sliding seat 63 will overcome the elastic force of the buffer spring 193 and drive the buffer block 191 to slide inside the buffer groove 192. In this process, the sliding seat 63 will press against the spring 8 to avoid motion interference.

[0054] In the embodiment provided by the present invention, a locking member 15 is arranged between the shell 1 and the power frame 147. When the adjustment seat 7 slides inside the shell 1 to adjust the elastic force released by the clamping spring 8, the locking member 15 fixes the adjusted adjustment seat 7; the locking member 15 includes a locking plate 151 slidably connected to the inside of the shell 1, a locking spring 153 is arranged between the locking plate 151 and the shell 1, and a locking groove 152 is opened on the power frame 147. The elastic force of the locking spring 153 drives the locking block to be clamped in the locking groove 152, so that the state of the adjustment seat 7 can be fixed.

[0055] In the embodiment provided by the present invention, an unlocking part is provided between the power frame 147 and the clamping plate 111. When the adjustment seat 7 slides inside the housing 1 to adjust the elastic force released by the abutting spring 8, the state of the clamping plate 111 is adjusted by the unlocking part so that the clamping plate 111 is away from the slider 10. The unlocking part includes an unlocking rod 16 fixedly connected to the power frame 147, an unlocking block 17 is fixedly connected to the unlocking rod 16, and an unlocking groove 18 adapted to the unlocking block 17 is provided on the positioning block 113, and the unlocking block 17 is intermittently abutted with the unlocking groove 18. In the stroke of driving the adjustment seat 7 to slide by the driving member 13, the unlocking rod 16 and the unlocking block 17 slide together, so that the unlocking block 17 slides into the unlocking groove 18, driving the positioning block 113 to drive the clamping plate 111 to slide to the side away from the slider 10, thereby reducing the friction between the clamping plate 111 and the slider 10. In this process, after the user knows that the spring 8 is not elastic enough, there is no need to use the clamping part 11 to limit the slider 10. At the same time, the clamping part 11 is unlocked passively during the sliding stroke of the adjustment seat 7, and there is no need to actively set the driving member 13 to drive the clamping part 11 to unfold, which has a better effect.

[0056] In the embodiment provided by the present invention, a driving disk 132 is installed on the end of the rotating rod 131. Specifically, a rotating groove is provided on the shell 1, wherein the driving disk 132 is installed in the rotating groove, and the driving disk 132 only protrudes about 0.5 mm, and a decorative strip is installed on the driving disk 132, and the decorative strips are distributed on the driving disk 132 in a circular array, which can increase the decorative effect and improve the friction when driving the driving disk 132 to rotate, and the use effect is better. A limiting portion is provided between the driving disk 132 and the shell 1. Specifically, the limiting portion includes an annular limiting strip fixedly connected to the driving disk 132, and an annular groove is provided on the shell 1, and the annular limiting strip is rotatably connected in the annular groove, so that the stability of the driving disk 132 during rotation can be improved, and external impurities can be prevented from entering the shell 1.

[0057] In the embodiment provided by the present invention, a reset member 136 is provided between the driving block 135 and the housing 1, and the reset member 136 includes a reset plate fixedly connected to the bottom of the housing 1, and a reset spring is provided between the reset plate and the housing 1. The elastic force of the reset spring drives the driving block 135 away from the connection frame 142, thereby increasing the damping for the rotation of the driving disk 132 and reducing the situation of accidental touch. At the same time, it is convenient for the driving block 135 to reset after completing the adjustment operation, meeting the working needs.
