[0001] The utility model relates to the technical field of electronic device brackets, and particularly relates to a clamping device. Background Art

[0002] With the popularization and diversification of electronic devices, the demand for electronic device brackets is increasing day by day. The main function of an electronic device bracket is to provide users with a stable and convenient way to place and use their electronic devices, such as tablet computers, smartphones, laptops, etc. Existing electronic device brackets are usually equipped with clamping devices, which are designed to clamp and fix the bracket on the edge of a table, the corner of a table, a car stereo screen or other supporting structures. However, existing clamping devices have some limitations in practical applications. They usually rely on two flat clamping surfaces to clamp an object. Although this design is simple, the anti-slip effect is generally average. Especially when the clamping device is loaded with a heavier device or used in a relatively large shaking environment (such as a car-mounted mobile phone bracket), there is a risk of shaking or even falling. Summary of the Utility Model

[0003] The purpose of the utility model is to provide a clamping device to solve the problem raised in the above background art: existing clamping devices usually rely on two flat clamping surfaces to clamp an object.

When the distance between the pushing member and the first clamping portion decreases, the abutting portion is used to abut against the second end of the movable clamping member to drive the first end of the movable clamping member to move close to the first clamping portion so as to be clamped with the first clamping portion. When the distance between the pushing member and the first clamping portion is the largest, the movable clamping member disengages from the first clamping portion under the action of elastic force.

Detailed implementation manners

[0028] The general idea of the technical solution provided by the present utility model is as follows:

[0029] Please refer to Figures 1 to 9 , a clamping device, including:

[0030] A connection base 100, one end of the connection base 100 is provided with a first clamping portion 110, the other end of the connection base 100 is provided with a second clamping portion 120 corresponding to the first clamping portion 110, the first clamping portion 110 is used to clamp an object with the second clamping portion 120, and a plurality of sunken accommodation cavities 200 are provided on the clamping end surface of the first clamping portion 110 and / or the second clamping portion 120 for clamping the object. A suction cup 210 is provided in the accommodation cavity 200, the suction cup 210 extends out of the accommodation cavity 200, and the accommodation cavity 200 is used to accommodate the suction cup 210 when the suction cup 210 is under pressure.

[0031] The connecting base 100 is the central supporting component of the clamping device, which provides structural stability and strength for the entire clamping device. One end of the connecting base 100 is provided with a first clamping portion 110, and the other end is provided with a second clamping portion 120. The first clamping portion 110 and the second clamping portion 120 are used to cooperate with each other to clamp an object. They can be independent components or extensions of the connecting base 100. The first clamping portion 110 and the second clamping portion 120 can be designed to be adjustable to adapt to objects of different thicknesses and shapes. Such designs are mature technologies in this field and will not be elaborated here.

[0032] A plurality of sunken receiving cavities 200 are provided on the clamping end faces of the first clamping portion 110 and / or the second clamping portion 120. These receiving cavities 200 are used to provide space for receiving the suction cups 210 when the suction cups 210 are under pressure, preventing the suction cups 210 from protruding from the clamping end faces of the first clamping portion 110 and / or the second clamping portion 120 and affecting the clamping effect.

[0033] The suction cups 210 are arranged in the receiving cavities 200 and protrude from the receiving cavities 200. The main function of the suction cups 210 is to provide additional adsorption force to help stably clamp an object, especially in occasions where it is necessary to prevent the clamping device from slipping or shaking. The suction cups 210 are usually made of soft and elastic materials, such as silicone or rubber. These materials can provide good adsorption force and can closely fit the surface of the object to be clamped. The shape of the suction cups 210 is usually circular or oval to facilitate evenly dispersing pressure and providing stable adsorption force. Their edges are designed to be able to closely fit the object surface to prevent air leakage, thereby maintaining the adsorption effect. When the suction cups 210 are pressed against the surface of an object, they will deform due to their own elasticity and external pressure to form a sealed edge. This sealed edge prevents air from entering between the suction cups 210 and the surface, thereby forming a low-pressure area inside the suction cups 210. The external atmospheric pressure presses the suction cups 210 against the surface to generate adsorption force.

[0034] By providing the first clamping portion 110 and the second clamping portion 120 at both ends of the connecting base 100, and arranging the suction cups 210 on the clamping end faces of the first clamping portion 110 and / or the second clamping portion 120 for clamping an object, additional adsorption force can be increased through the suction cups 210 when clamping the object, enabling the clamping device to clamp the object more stably, effectively avoiding the risk of falling caused by the heavy load or large shaking of the clamping device. In addition, when the object applies pressure to the clamping end face, the suction cups 210 can be received by the receiving cavities 200, making the clamping end face flat, having a larger contact area with the object, and not reducing the effective contact area with the object due to the protrusion of the suction cups 210, thereby further enhancing the clamping stability and adaptability.

[0035] To make the objectives, technical solutions, and advantages of the embodiments of the present utility model clearer, the following will clearly and completely describe the technical solutions in the embodiments of the present utility model with reference to the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are some, but not all, of the embodiments of the present utility model. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present utility model without creative efforts shall fall within the protection scope of the present utility model.

[0036] Please refer to Figure 1 , an anti-slip member 300 is provided on the clamping end face where the first clamping portion 110 and / or the second clamping portion 120 clamp an object, and a plurality of sunken receiving cavities 200 are provided on the anti-slip member 300. Specifically, the anti-slip member 300 can be made of a material with a high coefficient of friction, such as rubber, silica gel, or textured plastic. These materials can provide additional gripping force to prevent the object from sliding during the clamping process. The main purpose of the anti-slip member 300 is to increase the friction between the clamping end face and the object to be clamped, thereby improving the overall stability. The receiving cavity 200 is provided on the anti-slip member 300, and a suction cup 210 is provided in the receiving cavity 200. While the suction cup 210 provides an adsorption force, the anti-slip member 300 further provides additional friction, making the clamping more stable.

[0037] In addition to providing the anti-slip member 300 on the clamping end face where the first clamping portion 110 and / or the second clamping portion 120 clamp an object, the body of the first clamping portion 110 and / or the second clamping portion 120 can also be directly made of a material with a high coefficient of friction, thereby having the same effect as providing the anti-slip member 300 on the clamping end face where the first clamping portion 110 and / or the second clamping portion 120 clamp an object.

[0038] Please refer to Figure 1, the other end of the connecting base 100 is provided with a locking mechanism 400 and a ejector rod mechanism 500. The ejector rod mechanism 500 is movably connected to the connecting base 100. The locking mechanism 400 is used to control the movement of the ejector rod mechanism 500. One end of the ejector rod mechanism 500 facing the first clamping portion 110 is provided with a second clamping portion 120. The main function of the locking mechanism 400 is to control and lock the position and movement of the ejector rod mechanism 500. Through the locking mechanism 400, the user can control the position of the ejector rod mechanism 500. The main function of the ejector rod mechanism 500 is to provide an adjustable support structure for adjusting the distance between the first clamping portion 110 and the second clamping portion 120. By moving the ejector rod mechanism 500, objects of different sizes and thicknesses can be adapted to achieve flexible clamping. When the user needs to adjust the clamping device to adapt to objects of different sizes, the ejector rod mechanism 500 can be unlocked by operating the locking mechanism 400. Then, the user can move the ejector rod mechanism 500 manually or by other means to adjust the distance between the first clamping portion 110 and the second clamping portion 120. Once the required clamping distance is reached, the user can lock the position of the ejector rod mechanism 500 through the locking mechanism 400 to ensure that the clamping device remains stable during use.

[0039] Further, please refer to Figures 3 to 5 , the locking mechanism 400 includes a locking member 410 and a pushing member 420. The ejector rod mechanism 500 includes a rod portion 510 and a second clamping portion 120. The pushing member 420 is slidably connected to the other end of the connecting base 100. When the pushing member 420 slides, the distance between the pushing member 420 and the first clamping portion 110 can be changed; the pushing member 420 is telescopically connected to the rod portion 510 of the ejector rod mechanism 500. This connection method allows the user to adjust the relative position between the rod portion 510 and the pushing member 420. The locking member 410 is connected to the pushing member 420. The locking member 410 can drive the pushing member 420 to move. Once the position of the pushing member 420 is adjusted to a suitable position, the locking member 410 can lock the pushing member 420.

[0040] By driving the locking member 410 to change the distance between the pushing member 420 and the first clamping portion 110; when the distance between the pushing member 420 and the first clamping portion 110 is the largest, the telescopic connection between the pushing member 420 and the rod portion 510 is in an adjustable state; when the distance between the pushing member 420 and the first clamping portion 110 becomes smaller, the telescopic connection between the pushing member 420 and the rod portion 510 changes from an adjustable state to a non-adjustable state.

[0041] By driving the locking member 410 to change the distance between the pushing member 420 and the first clamping portion 110; when the distance between the pushing member 420 and the first clamping portion 110 is the largest, the telescopic connection between the pushing member 420 and the rod portion 510 is in an adjustable state, which means that the user can freely move the ejector rod mechanism 500 and adjust the distance between it and the first clamping portion 110 to adapt to objects of different sizes; when the distance between the pushing member 420 and the first clamping portion 110 becomes smaller, the telescopic connection between the pushing member 420 and the rod portion 510 changes from an adjustable state to a non-adjustable state. At this time, the pushing member 420 and the rod portion 510 are relatively fixed, and the pushing member 420 can push the second clamping portion 120 through the rod portion 510 to clamp the object together with the first clamping portion 110. After clamping the object, the locking member 410 locks the pushing member 420 at this time to prevent it from moving during use and ensure that the second clamping portion 120 and the first clamping portion 110 stably clamp the electronic device.

[0042] It can be understood that a locking and releasing mechanism may be included between the pushing member 420 and the ejector rod mechanism 500. When the distance between the pushing member 420 and the first clamping portion 110 is the largest, the locking mechanism is released, allowing the user to freely adjust the relative positions of the ejector rod mechanism 500 and the pushing member 420. As the distance between the pushing member 420 and the first clamping portion 110 becomes smaller, the locking mechanism is activated again to fix the relative positions of the ejector rod mechanism 500 and the pushing member 420. Alternatively, a snap or locking structure may be designed between the pushing member 420 and the rod portion 510, allowing the user to unlock by a simple pressing or triggering action when the distance between the pushing member 420 and the first clamping portion 110 is the largest, and then adjust the position of the ejector rod mechanism 500. After the adjustment is completed, press or trigger again to lock the position.

[0043] By driving the locking member 410 to change the distance between the pushing member 420 and the first clamping portion 110; when the distance between the pushing member 420 and the first clamping portion 110 is the largest, the telescopic connection between the pushing member 420 and the rod portion 510 is in an adjustable state, that is, the distance between the rod portion 510 and the pushing member 420 can be telescopically adjusted, and the rod portion 510 can drive the second clamping portion 120 to move, so as to adjust the distance between the second clamping portion 120 and the first clamping portion 110, and realize the adjustment of the space for clamping an object; after adjusting the space for clamping an object, when the distance between the pushing member 420 and the first clamping portion 110 becomes smaller by driving the locking member 410, the telescopic connection between the pushing member 420 and the rod portion 510 changes from an adjustable state to a non-adjustable state, so that the pushing member 420 can drive the rod portion 510 to clamp the second clamping portion 120 and the first clamping portion 110 on the object. By driving the locking member 410, the adjustable clamping space between the second clamping portion 120 and the first clamping portion 110 can be realized, so as to adapt to screens of different sizes and thicknesses. After adjusting the appropriate clamping space, driving the locking member 410 makes the distance between the pushing member 420 and the first clamping portion 110 decrease, prompting the telescopic connection between the pushing member 420 and the rod portion 510 to become a non-adjustable state, and the pushing member 420 can drive the ejector rod mechanism 500 with a fixed distance to clamp the object, ensuring its stable clamping, thereby improving the versatility and practicality

[0044] Please refer to Figure 4 and Figure 5, the clamping device further includes a movable clamping member 600. A first clamping portion 511 is provided on the side of the rod portion 510 facing the pushing member 420, and an abutting portion 130 is provided on the side of the connecting base 100 facing the pushing member 420. The movable clamping member 600 is displaceably inserted through the pushing member 420. The first end 610 of the movable clamping member 600 faces the first clamping portion 511, and the second end 620 of the movable clamping member 600 faces the abutting portion 130. The movable clamping member 600 is elastically connected to the pushing member 420. When the distance between the pushing member 420 and the first clamping portion 110 decreases, the abutting portion 130 is used to abut against the second end 620 of the movable clamping member 600 to drive the first end 610 of the movable clamping member 600 to move closer to the first clamping portion 511 so as to be clamped with the first clamping portion 511. When the distance between the pushing member 420 and the first clamping portion 110 is the largest, the movable clamping member 600 disengages from the first clamping portion 511 under the action of the elastic force. Specifically, the movable clamping member 600 is designed to be displaceably inserted through the pushing member 420. This design allows the movable clamping member 600 to move on the pushing member 420. The elastic connection between the movable clamping member 600 and the pushing member 420 means that there is a certain elastic force between the movable clamping member 600 and the pushing member 420, which can push the movable clamping member 600 back to the initial position. When the distance between the pushing member 420 and the first clamping portion 110 decreases, the pushing member 420 will drive the movable clamping member 600 to move closer to the abutting portion 130. As the movable clamping member 600 contacts the abutting portion 130, the abutting portion 130 will abut against the second end 620 of the movable clamping member 600, driving the first end 610 of the movable clamping member 600 to move closer to the first clamping portion 511, so as to achieve clamping with the first clamping portion 511.

[0045] Please refer to Figure 6 , the abutting portion 130 is a structure that gradually protrudes along the direction in which the movable clamping member 600 moves closer to the abutting portion 130. Please refer to Figure 7 , when the distance between the pushing member 420 and the first clamping portion 110 is the largest, the movable clamping member 600 remains in the initial state under the elastic force of the elastic connection with the pushing member 420. At this time, the second end 620 of the movable clamping member 600 does not contact the first clamping portion 511. At this time, the ejector rod mechanism 500 can move freely relative to the pushing member 420, that is, when the distance between the pushing member 420 and the first clamping portion 110 is the largest, the telescopic connection between the pushing member 420 and the rod portion 510 is in an adjustable state; Please refer to Figure 8When the distance between the pusher 420 and the first clamping part 110 decreases, the pusher 420 drives the movable latch 600 to move in the direction close to the abutting top part 130. The convex part of the abutting top part 130 will gradually abut against the second end 620 of the movable latch 600, pushing the first end 610 of the movable latch 600 close to the first clamping part 511 and engaging with the first clamping part 511. At this time, the ejector rod mechanism 500 is relatively fixed to the pusher 420 through the engagement of the movable latch 600 and the first clamping part 511. Therefore, when the distance between the pusher 420 and the first clamping part 110 decreases, the telescopic connection between the pusher 420 and the rod part 510 changes from an adjustable state to a non-adjustable state.

[0046] Please refer to Figure 5 and Figure 9 The first clamping part 511 is provided with a plurality of first teeth 5111, and the first end 610 of the movable latch 600 is provided with a plurality of second teeth 611. The first teeth 5111 are used for meshing connection with the second teeth 611. Specifically, when the distance between the pusher 420 and the first clamping part 110 decreases, the first end 610 of the movable latch 600 will approach the first clamping part 511, and the second teeth 611 will mesh with the first teeth 5111, so as to realize the engagement between the first end 610 of the movable latch 600 and the first clamping part 511.

[0047] Please refer to Figures 1 to 4 The clamping device further includes: an adapter 700. The adapter 700 is used to connect an electronic device, and the adapter 700 is movably connected to the connection base 100. Specifically, the adapter 700 can be connected to an electronic device (such as a mobile phone) through a bracket or directly connected to the electronic device. Since the adapter 700 is a mature technology in the art, it will not be elaborated here. It can adopt some widely recognized design schemes, such as a universal ball head, a magnetic suction bracket, etc., which are not limited thereto. The adapter 700 and the connection base 100 are movably connected, which means that the user can adjust the distance between the adapter 700 and the connection base 100;

[0048] By driving the locking mechanism 400 to control the distance between the adapter 700 and the connection base 100, when the distance between the adapter 700 and the connection base 100 is at its maximum, the adapter 700 and the connection base 100 are in a rotatable connection state. When the distance between the adapter 700 and the connection base 100 becomes smaller, the adapter 700 and the connection base 100 are in a non-rotatable connection state. Specifically, the user controls the distance between the adapter 700 and the connection base 100 by driving the locking mechanism 400. When the distance between the adapter 700 and the connection base 100 reaches the maximum, they are in a rotatable connection state, allowing the user to freely adjust the angle between the adapter 700 and the connection base 100, thereby adjusting the angle of the electronic device. When the distance decreases, the adapter 700 and the connection base 100 are in a non-rotatable connection state, completing the angle adjustment.

[0049] When the distance between the adapter 700 and the connection base 100 reaches the maximum by driving the locking mechanism 400, their connection becomes a rotatable state. At this time, the user can easily adjust the angle between the adapter 700 and the connection base 100, thereby adjusting the angle of the electronic device. When the distance between the adapter 700 and the connection base 100 becomes smaller, the adapter 700 and the connection base 100 become a non-rotatable connection state. At this time, the angle between the adapter 700 and the connection base 100 is fixed, thereby completing the angle adjustment of the electronic device. In this way, the user can conveniently adjust the angle of the electronic device according to actual needs, which not only improves the flexibility of use but also ensures that the electronic device maintains the best operating posture during use, greatly enhancing the user experience.

[0050] Please refer to Figure 2 and Figure 3 As shown in, the pusher 420 is provided with a limiting portion 421. A movable space for the adapter 700 is formed between the limiting portion 421 and the connection base 100. By driving the locking member 410 to control the displacement of the pusher 420, the distance between the limiting portion 421 and the connection base 100 is controlled. Specifically, when the pusher 420 moves, the distance between the limiting portion 421 and the connection base 100 changes, thereby controlling the moving distance of the adapter 700.

[0051] Please refer to Figure 2, one end of the adapter 700 is provided with a second clamping portion 710, and the connection base 100 is provided with a third clamping portion 140 that matches the second clamping portion 710. The second clamping portion 710 is used to be clamped with the third clamping portion 140. When the distance between the adapter 700 and the connection base 100 is at its maximum, the second clamping portion 710 and the third clamping portion 140 for connecting are not clamped. When the distance between the adapter 700 and the connection base 100 becomes smaller, the second clamping portion 710 is clamped with the third clamping portion 140. Specifically, the second clamping portion 710 and the third clamping portion 140 can be mechanical interfaces of any form, such as tooth-shaped, notch, protrusion, etc., for realizing the clamping and locking functions. When the distance between the adapter 700 and the connection base 100 is at its maximum, no clamping occurs between the second clamping portion 710 and the third clamping portion 140, which allows the user to freely rotate the adapter 700 to adjust the angle of the electronic device. As the adapter 700 approaches the connection base 100, the second clamping portion 710 and the third clamping portion 140 start to be clamped, thus locking the relative position between the adapter 700 and the connection base 100, and the two cannot rotate relative to each other. The design of this clamping mechanism enables the user to easily perform the clamping and unlocking operations, thereby completing the switching between the states where the adapter 700 and the connection base 100 can and cannot rotate relative to each other, while ensuring sufficient stability in the locked state.

[0052] Please refer to Figure 2 , the second clamping portion 710 includes a first tooth portion 711, and the third clamping portion 140 includes a second tooth portion 141 that matches the first tooth portion 711. The first tooth portion 711 is used to be meshed and connected with the second tooth portion 141. Specifically, the first tooth portion 711 and the second tooth portion 141 are structurally designed to be able to bite with each other. When the adapter 700 approaches the connection base 100, the first tooth portion 711 and the second tooth portion 141 start to be meshed, thus locking the relative position between the two. The meshed connection of the first tooth portion 711 and the second tooth portion 141 can provide a stable locking effect to prevent the device from rotating accidentally during use.

[0053] More specifically, the locking member 410 is designed to be able to drive the pushing member 420 to move. This driving mechanism may include manual operations such as rotation, pressing, or sliding, enabling the user to adjust the position of the pushing member 420 as needed. Further, once the position of the pushing member 420 is adjusted to the appropriate position, the locking member 410 can lock the pushing member 420 to prevent it from moving during use. This locking mechanism is used to restrict the movement of the adapter 700. It can be understood that this design of driving plus locking can be completed using common designs in the art, such as screw-nut connections, snap connections, etc., which are not limited herein. More specifically, in a screw-nut connection, the locking member 410 can be implemented using structures such as a screw and a nut. The screw can be rotated into the nut to drive the pushing member 420 to move through the rotation action, while the nut can fix the screw to prevent it from rotating back, thereby locking the position of the pushing member 420.

[0054] Further, please refer to Figure 5 , the locking member 410 is rotatably connected to the other end of the connection base 100. The locking member 410 is provided with a buckling portion 411 and an acting portion 412 extending outward along the rotation axis. The buckling portion 411 is used to drive the locking member 410 to rotate, and the acting portion 412 is used to follow the rotation of the locking member 410 and act on the pushing member 420 to drive the pushing member 420 to move. Specifically, one end of the locking member 410 and the connection base 100 can be rotatably connected through a rotating shaft 430.

[0055] Specifically, the buckling part 411 is a structure that extends outward along the rotation axis on the locking member 410. The user can rotate the locking member 410 by applying a force to the buckling part 411. The acting part 412 also extends outward along the rotation axis. When the locking member 410 rotates, the acting part 412 will rotate together with the locking member 410 and act on the pushing member 420. The function of the acting part 412 is to interact with the pushing member 420. This interaction can be a simple abutment, or an abutment plus a pulling action. This abutment and pulling action drives the pushing member 420 to move in a predetermined direction, thereby realizing the driving of the pushing member 420. More specifically, the abutment action means that when the acting part 412 rotates to a position in contact with the pushing member 420, continuously rotating the locking member 410 will cause the acting part 412 to exert a direct thrust on the pushing member 420. This thrust can be perpendicular to the surface of the pushing member 420 or applied at a specific angle, depending on the design of the pushing member 420 and the required movement direction. The abutment action is used to move the pushing member 420 in the direction close to the first clamping part 110, so that the distance between the pushing member 420 and the first clamping part 110 becomes smaller. The pulling action requires additional mechanical design. For example, the acting part 412 can be designed with a structure that can grasp or buckle the pushing member 420, and then as the locking member 410 rotates, the acting part 412 pulls the pushing member 420. The pulling action is used to move the pushing member 420 in the direction away from the first clamping part 110, so that the distance between the pushing member 420 and the first clamping part 110 becomes larger.

[0056] After the pushing member 420 moves to a suitable position, the locking member 410 can lock the pushing member 420 to prevent it from moving during use. Specifically, please refer to Figure 5 , the acting part 412 includes a first part 4121 and a second part 4122. The distance from the first part 4121 to the rotation axis of the locking member 410 is larger than the distance from the second part 4122 to the rotation axis of the locking member 410. In the initial state, the second part 4122 of the locking member 410 abuts against the pushing member 420. At this time, the pushing member 420 is in the first position. When the user needs to adjust the position of the pushing member 420, the locking member 410 can be rotated. As the locking member 410 rotates, the first part 4121 comes into contact with the pushing member 420 and begins to abut and push the pushing member 420 to move. Since the first part 4121 is farther from the rotation axis, the first part 4121 can abut and push the pushing member 420 to displace a certain distance, so that after the pushing member 420 moves to the second position, the first part 4121 locks the pushing member 420 in the second position. This design realizes the adjustment and locking of the pushing member 420 through a simple rotation action, with simple operation and stability. The user can easily adjust and fix the clamping device without additional tools.

[0057] Please refer to Figure 4, an elastic member 520 is provided between the pushing member 420 and the rod portion 510. The elastic member 520 is used to provide a force for the pushing member 420 to move away from the first clamping portion 110. Specifically, when the rod portion 510 is stressed, the rod portion 510 can provide a force for the pushing member 420 to move away from the first clamping portion 110 through the elastic member 520, so that the distance between the pushing member 420 and the first clamping portion 110 becomes larger. In this design, the acting portion 412 does not need to pull the pushing member 420 to make the distance between the pushing member 420 and the first clamping portion 110 larger, thereby simplifying the structure of the acting portion 412. If there is no elastic member 520 between the pushing member 420 and the rod portion 510, it is necessary to pull the pushing member 420 through the acting portion 412 to make the distance between the pushing member 420 and the first clamping portion 110 larger.

[0058] Please refer to Figure 5 , the elastic member 520 includes a second spring member 521. One end of the second spring member 521 abuts against the pushing member 420, and the other end of the second spring member 521 abuts against the rod portion 510. Specifically, the second spring member 521 can provide a tension force for the pushing member 420 and the rod portion 510 to move away from each other. When the distance between the pushing member 420 and the first clamping portion 110 is the largest, the telescopic connection between the pushing member 420 and the rod portion 510 is in an adjustable state. The second spring member 521 can push the pushing member 420 and the rod portion 510 to be in the maximum extended state. The tension of the second spring member 521 can be transmitted to the second clamping portion 120 through the rod portion 510, so that the second clamping portion 120 and the first clamping portion 110 can maintain a certain clamping force when clamping objects of different thicknesses, thereby realizing the adaptive clamping of objects of different thicknesses.

[0059] Please refer to Figure 9 , a first spring member 630 is provided between the movable clamping member 600 and the pushing member 420. The movable clamping member 600 and the pushing member 420 are elastically connected through the first spring member 630. The first spring member 630 provides a tension force for the movable clamping member 600 to move in the direction of the abutting portion 130. The movable clamping member 600 will have a certain displacement when being abutted by the abutting portion 130, but can return to the initial position through the restoring force of the first spring member 630 after not being abutted by the abutting portion 130.
