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 tablets, smartphones, laptops, etc. Existing electronic device brackets are usually equipped with clamping devices, which are designed to clamp and fix the brackets on the edge of a table, the corner of a table, a car stereo screen or other support structures. However, some existing clamping devices usually adopt a flat tray structure to clamp an object. When locking the object, it is difficult for this flat tray structure to closely adhere to the curved surface of the object, resulting in a small contact area and weak grasping force. Especially in a violently shaking or vibrating environment, the object is prone to lateral sliding, resulting in insecure clamping. Summary of the Utility Model

Detailed implementation manners

[0030] The general idea of the technical solution provided by the present utility model is as follows:

[0031] Please refer to Figures 1 to 11 , a clamping device, comprising:

[0032] A connection base 100, one end of the connection base 100 is provided with a clamping part 110, the other end of the connection base 100 is provided with a tray member 120, a space for clamping an object is formed between the tray member 120 and the clamping part 110, the clamping end face 121 of the tray member 120 for clamping the object has a concave structure 126, and the tray member 120 has elasticity, so that the tray member 120 can be deformed when subjected to an external force and return to its original state after the external force is removed.

[0033] The connection base 100 is the central support component of the clamping device, which provides structural stability and strength for the entire clamping device. One end of the connection base 100 is provided with a clamping part 110, and the other end is provided with a tray member 120. The clamping part 110 and the tray member 120 are used to cooperate with each other to clamp an object. They can be independent components or extensions of the connection base 100. The clamping part 110 and the tray member 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.

[0034] The clamping end face 121 of the tray member 120 for clamping an object has a concave structure 126. The concave structure 126 can be designed according to the shape of the object, and can be a single groove or a combination of multiple grooves to adapt to the curved surfaces of different parts. The concave structure 126 can be evenly distributed on the entire clamping end face 121 or concentrated in a specific area, depending on the shape of the object and the clamping requirements. The concave structure 126 enables the clamping end face 121 of the tray member 120 to better conform to the curved surface of the object. This design is particularly suitable for clamping objects with curved or irregular shapes, such as the casings of some electronic devices. Through the concave design of the concave structure 126, the contact area between the tray member 120 and the object increases, which helps to disperse the clamping force, reduce the pressure points on the object surface, and thus reduce the risk of damaging the object surface. In addition, a larger contact area means a stronger gripping force, which helps to keep the object stable under various operating conditions.

[0035] The tray member 120 has elasticity, and the elastic property is an important design feature of the tray member 120 in the clamping device. It allows the tray member 120 to deform when subjected to an external force and return to its original shape after the external force is removed. Due to the elasticity of the tray member 120, it can adapt to objects of different sizes and shapes. When clamping a curved object, the tray member 120 can deform accordingly according to the contour of the object to ensure close fit with the object surface, thereby providing a uniform clamping force. The tray member 120 can be made of materials with natural elasticity, such as silica gel, rubber, thermoplastic elastomer (TPE), polyurethane (PU), etc. These materials can deform when subjected to an external force and return to their original state after the external force is removed. Or spring or other elastic elements can be added to the tray member 120. These elements can be compressed when subjected to pressure and return to their original state after the pressure is removed.

[0036] By providing a clamping end face 121 with a concave structure 126 on the tray member 120 and the tray member 120 having elasticity, when clamping an object with a curved surface, the tray member 120 can deform to a certain extent according to the curved surface shape of the object, thereby increasing the contact area with the object, improving the gripping force and stability. Compared with the traditional flat tray structure, this design makes the clamping device more firm when subjected to an external force and is not prone to lateral sliding. Especially in a violently shaking or vibrating environment, it can also keep the object stable and provide more reliable support.

[0037] To make the objectives, technical solutions, and advantages of the embodiments of the present utility model clearer, the technical solutions in the embodiments of the present utility model will be clearly and completely described below with reference to the accompanying drawings in the embodiments of the present utility model. Apparently, 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.

[0038] Please refer to Figure 1 , Figure 2 and Figure 11 , on the clamping end face 121 of the tray member 120, a plurality of suction cups 122 are provided. Specifically, the main function of the suction cups 122 is to provide additional adsorption force to help stably clamp an object, especially in situations where it is necessary to prevent the clamping device from slipping or shaking. The suction cups 122 are usually made of soft and elastic materials. The discs are usually made of soft and elastic materials such as silica gel or rubber. These materials can provide good adsorption force and can closely fit on the surface of the object to be clamped. The shape of the suction cups 122 is usually circular or oval to facilitate evenly dispersing pressure and providing stable adsorption force. Their edges are designed to closely fit on the object surface to prevent air leakage, thereby maintaining the adsorption effect. When the suction cups 122 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 122 and the surface, thereby forming a low-pressure area inside the suction cups 122. The external atmospheric pressure presses the suction cups 122 against the surface to generate adsorption force.

[0039] Please refer to Figure 2 , on the clamping end face 121 of the tray member 120, a plurality of sunken receiving cavities 123 are provided. The suction cups 122 are arranged in the receiving cavities 123, and the suction cups 122 protrude from the receiving cavities 123. The receiving cavities 123 are used to accommodate the suction cups 122 when the suction cups 122 are under pressure. Specifically, these receiving cavities 123 are used to provide space to accommodate the suction cups 122 when the suction cups 122 are under pressure, preventing the suction cups 122 from protruding from the clamping end face 121 and affecting the clamping effect. When an object applies pressure to the clamping end face 121, the suction cups 122 can be received by the receiving cavities 123, making the clamping end face 121 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 122, thereby further improving the clamping stability and adaptability.

[0040] Please refer to Figure 1 and Figure 2, the clamping portion 110 is provided with a first anti-slip member 111, and a second anti-slip member 124 is provided on the clamping end face 121 of the tray member 120. The accommodating cavity 123 and the suction cup 122 are provided on the second anti-slip member 124. Specifically, the first anti-slip member 111 and the second anti-slip member 124 can be made of materials with a high coefficient of friction, such as rubber, silicone, or textured plastic. These materials can provide additional gripping force to prevent the object from sliding during clamping. The main purpose of the first anti-slip member 111 and the second anti-slip member 124 is to increase the friction force between the clamping end face 121 and the object being clamped, thereby improving the overall stability. The accommodating cavity 123 and the suction cup 122 are provided on the second anti-slip member 124. While the suction cup 122 provides an adsorption force, the second anti-slip member 124 further provides additional friction force, making the clamping more stable.

[0041] In addition to providing the second anti-slip member 124 on the clamping end face 121 of the tray member 120, the body of the tray member 120 can also be directly made of a material with a high coefficient of friction, thereby having the same effect as providing the second anti-slip member 124 on the clamping end face 121 of the tray member 120.

[0042] Please refer to Figure 11 , the two outer edges 125 of the clamping end face 121 of the tray member 120 extend outward in perpendicular directions. In this way, the two outer edges 125 of the clamping end face 121 can accommodate objects with right-angled edges, such as car stereo screens, tablet computers, navigation devices, etc. The perpendicular outer edge 125 design can well fit the right-angled edge of the object, providing a stable support point to prevent the object from sliding or tilting during clamping.

[0043] Please refer to Figure 1 and Figure 2, at the other end of the connecting base 100, there is a locking mechanism 200 and a push rod mechanism 300. The push rod mechanism 300 is movably connected to the connecting base 100. The locking mechanism 200 is used to control the movement of the push rod mechanism 300. At one end of the push rod mechanism 300 facing the clamping part 110, there is a tray part 120. The main function of the locking mechanism 200 is to control and lock the position and movement of the push rod mechanism 300. Through the locking mechanism 200, the user can control the position of the push rod mechanism 300. The main function of the push rod mechanism 300 is to provide an adjustable support structure for adjusting the distance between the clamping part 110 and the tray part 120. By moving the push rod mechanism 300, it can adapt to objects of different sizes and thicknesses to achieve flexible clamping. When the user needs to adjust the clamping device to adapt to objects of different sizes, the user can operate the locking mechanism 200 to unlock the push rod mechanism 300. Then, the user can move the push rod mechanism 300 manually or by other means to adjust the distance between the clamping part 110 and the tray part 120. Once the required clamping distance is reached, the user can lock the position of the push rod mechanism 300 through the locking mechanism 200 to ensure that the clamping device remains stable during use.

[0044] Further, please refer to Figures 3 to 6 , the locking mechanism 200 includes a locking part 210 and a pushing part 220. The push rod mechanism 300 includes a rod part 310 and a tray part 120. The pushing part 220 is slidably connected to the other end of the connecting base 100. When the pushing part 220 slides, it can change the distance between the pushing part 220 and the clamping part 110; the pushing part 220 is telescopically connected to the rod part 310 of the push rod mechanism 300. This connection method allows the user to adjust the relative position between the rod part 310 and the pushing part 220. The locking part 210 is connected to the pushing part 220; the locking part 210 can drive the pushing part 220 to move. Once the position of the pushing part 220 is adjusted to a suitable position, the locking part 210 can lock the pushing part 220;

[0045] By driving the locking part 210 to change the distance between the pushing part 220 and the clamping part 110; when the distance between the pushing part 220 and the clamping part 110 is the largest, the telescopic connection between the pushing part 220 and the rod part 310 is in an adjustable state; when the distance between the pushing part 220 and the clamping part 110 becomes smaller, the telescopic connection between the pushing part 220 and the rod part 310 changes from an adjustable state to a non-adjustable state.

[0046] By driving the locking member 210 to change the distance between the pushing member 220 and the clamping portion 110; when the distance between the pushing member 220 and the clamping portion 110 is the largest, the telescopic connection between the pushing member 220 and the rod portion 310 is in an adjustable state, which means that the user can freely move the ejector rod mechanism 300 and adjust the distance between it and the clamping portion 110 to adapt to objects of different sizes; when the distance between the pushing member 220 and the clamping portion 110 becomes smaller, the telescopic connection between the pushing member 220 and the rod portion 310 changes from an adjustable state to a non-adjustable state. At this time, the pushing member 220 and the rod portion 310 are relatively fixed, and the pushing member 220 can push the tray member 120 through the rod portion 310 to clamp the object together with the clamping portion 110. After clamping the object, the locking member 210 locks the pushing member 220 at this time to prevent it from moving during use and ensure that the tray member 120 and the clamping portion 110 stably clamp the electronic device.

[0047] It can be understood that a locking and releasing mechanism may be included between the pushing member 220 and the ejector rod mechanism 300. When the distance between the pushing member 220 and the 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 300 and the pushing member 220. As the distance between the pushing member 220 and the clamping portion 110 becomes smaller, the locking mechanism is activated again to fix the relative positions of the ejector rod mechanism 300 and the pushing member 220. Alternatively, a snap or lock structure can be designed between the pushing member 220 and the rod portion 310, allowing the user to unlock by a simple pressing or triggering action when the distance between the pushing member 220 and the clamping portion 110 is the largest, and then adjust the position of the ejector rod mechanism 300. After the adjustment is completed, press or trigger again to lock the position.

[0048] By driving the locking member 210 to change the distance between the pushing member 220 and the clamping portion 110; when the distance between the pushing member 220 and the clamping portion 110 is the largest, the telescopic connection between the pushing member 220 and the rod portion 310 is in an adjustable state, that is, the distance between the rod portion 310 and the pushing member 220 can be telescopically adjusted, and the rod portion 310 can drive the tray member 120 to move, so as to adjust the distance between the tray member 120 and the 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 220 and the clamping portion 110 becomes smaller by driving the locking member 210, the telescopic connection between the pushing member 220 and the rod portion 310 changes from an adjustable state to a non-adjustable state, so that the pushing member 220 can drive the rod portion 310 to clamp the tray member 120 and the clamping portion 110 on the object. By driving the locking member 210, the adjustable clamping space between the tray member 120 and the 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 210 reduces the distance between the pushing member 220 and the clamping portion 110, prompting the telescopic connection between the pushing member 220 and the rod portion 310 to become a non-adjustable state, and the pushing member 220 can drive the ejector rod mechanism 300 with a fixed distance to clamp the object, ensuring its stable clamping, thereby improving the versatility and practicality

[0049] Please refer to Figure 5 、 Figure 6 and Figure 10, the clamping device further includes a movable clamping member 400. A first clamping portion 311 is provided on the side of the rod portion 310 facing the pushing member 220, and an abutting portion 130 is provided on the side of the connecting base 100 facing the pushing member 220. The movable clamping member 400 is displaceably disposed on the pushing member 220. The first end 410 of the movable clamping member 400 faces the first clamping portion 311, and the second end 420 of the movable clamping member 400 faces the abutting portion 130. The movable clamping member 400 is elastically connected to the pushing member 220. When the distance between the pushing member 220 and the clamping portion 110 decreases, the abutting portion 130 is configured to abut against the second end 420 of the movable clamping member 400 to drive the first end 410 of the movable clamping member 400 to move closer to the first clamping portion 311 so as to be clamped with the first clamping portion 311. When the distance between the pushing member 220 and the clamping portion 110 is at its maximum, the movable clamping member 400 disengages from the first clamping portion 311 under the action of the elastic force. Specifically, the movable clamping member 400 is designed to be displaceably disposed on the pushing member 220. This design allows the movable clamping member 400 to move on the pushing member 220. The elastic connection between the movable clamping member 400 and the pushing member 220 means that there is a certain elastic force between the movable clamping member 400 and the pushing member 220, which can push the movable clamping member 400 back to its initial position. When the distance between the pushing member 220 and the clamping portion 110 decreases, the pushing member 220 will drive the movable clamping member 400 to move closer to the abutting portion 130. As the movable clamping member 400 comes into contact with the abutting portion 130, the abutting portion 130 will abut against the second end 420 of the movable clamping member 400, driving the first end 410 of the movable clamping member 400 to move closer to the first clamping portion 311, thereby achieving clamping with the first clamping portion 311.

[0050] Please refer to Figure 7 , the abutting portion 130 is a structure that gradually protrudes along the direction in which the movable clamping member 400 moves closer to the abutting portion 130. Please refer to Figure 8 , when the distance between the pushing member 220 and the clamping portion 110 is at its maximum, the movable clamping member 400 remains in its initial state under the elastic force of the elastic connection with the pushing member 220. At this time, the second end 420 of the movable clamping member 400 does not come into contact with the first clamping portion 311. At this time, the ejector rod mechanism 300 can move freely relative to the pushing member 220, that is, when the distance between the pushing member 220 and the clamping portion 110 is at its maximum, the telescopic connection between the pushing member 220 and the rod portion 310 is in an adjustable state; Please refer to Figure 9, when the distance between the pushing member 220 and the clamping portion 110 decreases, the pushing member 220 drives the movable locking member 400 to move in the direction approaching the abutting portion 130. The convex portion of the abutting portion 130 will gradually abut against the second end 420 of the movable locking member 400, pushing the first end 410 of the movable locking member 400 closer to the first engaging portion 311 and engaging with the first engaging portion 311. At this time, the ejector rod mechanism 300 is relatively fixed to the pushing member 220 through the engagement of the movable locking member 400 and the first engaging portion 311. Thus, when the distance between the pushing member 220 and the clamping portion 110 decreases, the telescopic connection between the pushing member 220 and the rod portion 310 changes from an adjustable state to a non-adjustable state.

[0051] Please refer to Figure 6 and Figure 10 , the first engaging portion 311 is provided with a plurality of first teeth 3111, and the first end 410 of the movable locking member 400 is provided with a plurality of second teeth 411. The first teeth 3111 are used for meshing connection with the second teeth 411. Specifically, when the distance between the pushing member 220 and the clamping portion 110 decreases, the first end 410 of the movable locking member 400 will approach the first engaging portion 311, and the second teeth 411 will mesh with the first teeth 3111, thereby realizing the engagement between the first end 410 of the movable locking member 400 and the first engaging portion 311.

[0052] Please refer to Figures 2 to 5 , the clamping device further includes: an adapter 500. The adapter 500 is used to connect to an electronic device, and the adapter 500 is movably connected to the connection base 100; specifically, the adapter 500 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 500 is a mature technology in this field, it will not be elaborated here. It can adopt some widely recognized design solutions, such as a universal ball head, a magnetic suction bracket, etc., and is not limited thereto. The adapter 500 and the connection base 100 are movably connected, which means that the user can adjust the distance between the adapter 500 and the connection base 100;

[0053] By driving the locking mechanism 200 to control the distance between the adapter 500 and the connection base 100, when the distance between the adapter 500 and the connection base 100 is at its maximum, the adapter 500 and the connection base 100 are in a rotatable connection state. When the distance between the adapter 500 and the connection base 100 decreases, the adapter 500 and the connection base 100 are in a non-rotatable connection state. Specifically, the user controls the distance between the adapter 500 and the connection base 100 by driving the locking mechanism 200. When the distance between the adapter 500 and the connection base 100 reaches its maximum, they are in a rotatable connection state, allowing the user to freely adjust the angle between the adapter 500 and the connection base 100, thereby adjusting the angle of the electronic device. When the distance decreases, the adapter 500 and the connection base 100 will be in a non-rotatable connection state, completing the angle adjustment.

[0054] By driving the locking mechanism 200 and controlling the distance between the adapter 500 and the connection base 100 to reach its maximum, the connection between the two becomes a rotatable state. At this time, the user can easily adjust the angle between the adapter 500 and the connection base 100, thereby adjusting the angle of the electronic device. When the distance between the adapter 500 and the connection base 100 decreases, the adapter 500 and the connection base 100 become a non-rotatable connection state. At this time, the angle between the adapter 500 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.

[0055] Please refer to Figure 3 and Figure 4 As shown in, the pusher 220 is provided with a limiting portion 221. A movable space for the adapter 500 is formed between the limiting portion 221 and the connection base 100. By driving the locking member 210 to control the displacement of the pusher 220, the distance between the limiting portion 221 and the connection base 100 is controlled. Specifically, when the pusher 220 moves, the distance between the limiting portion 221 and the connection base 100 changes, thereby controlling the moving distance of the adapter 500.

[0056] Please refer to Figure 3, one end of the adapter 500 is provided with a second engaging portion 510, and the connection base 100 is provided with a third engaging portion 140 that matches the second engaging portion 510. The second engaging portion 510 is used to engage with the third engaging portion 140. When the distance between the adapter 500 and the connection base 100 is at its maximum, the second engaging portion 510 and the third engaging portion 140 are not engaged. When the distance between the adapter 500 and the connection base 100 decreases, the second engaging portion 510 engages with the third engaging portion 140. Specifically, the second engaging portion 510 and the third engaging portion 140 can be any form of mechanical interface, such as teeth, notches, protrusions, etc., for achieving the engaging and locking functions. When the distance between the adapter 500 and the connection base 100 is at its maximum, no engagement occurs between the second engaging portion 510 and the third engaging portion 140, which allows the user to freely rotate the adapter 500 to adjust the angle of the electronic device. As the adapter 500 approaches the connection base 100, the second engaging portion 510 and the third engaging portion 140 start to engage, thus locking the relative position between the adapter 500 and the connection base 100, and the two cannot rotate relative to each other. The design of this engaging mechanism enables the user to easily perform the engaging and unlocking operations, thereby completing the switching between the states where the adapter 500 and the connection base 100 can and cannot rotate relative to each other, while ensuring sufficient stability in the locked state.

[0057] Please refer to Figure 3 , the second engaging portion 510 includes a first tooth portion 511, and the third engaging portion 140 includes a second tooth portion 141 that matches the first tooth portion 511. The first tooth portion 511 is used to engage with the second tooth portion 141 in a meshing connection. Specifically, the first tooth portion 511 and the second tooth portion 141 are structurally designed to be able to bite into each other. When the adapter 500 approaches the connection base 100, the first tooth portion 511 and the second tooth portion 141 start to mesh, thus locking the relative position between the two. The meshing connection between the first tooth portion 511 and the second tooth portion 141 can provide a stable locking effect to prevent the device from accidentally rotating during use.

[0058] More specifically, the locking member 210 is designed to be able to drive the pushing member 220 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 220 as needed. Further, once the position of the pushing member 220 is adjusted to a suitable position, the locking member 210 can lock the pushing member 220 to prevent it from moving during use. This locking mechanism is used to restrict the movement of the adapter 500. It can be understood that this design of driving and locking can be accomplished 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 210 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 220 to move through the rotational movement, while the nut can fix the screw to prevent it from rotating back, thereby locking the position of the pushing member 220.

[0059] Further, please refer to Figure 6 , the locking member 210 is rotatably connected to the other end of the connection base 100. The locking member 210 is provided with a clamping portion 211 and an acting portion 212 extending outward along the rotation axis. The clamping portion 211 is used to drive the locking member 210 to rotate, and the acting portion 212 is used to follow the rotation of the locking member 210 and act on the pushing member 220 to drive the pushing member 220 to move. Specifically, one end of the locking member 210 and the connection base 100 can be rotatably connected through a rotating shaft 213.

[0060] Specifically, the pressing part 211 is a structure that extends outward along the rotation axis on the locking part 210. The user can rotate the locking part 210 by applying a force to the pressing part 211. The acting part 212 also extends outward along the rotation axis. When the locking part 210 rotates, the acting part 212 will rotate together with the locking part 210 and act on the pushing part 220. The function of the acting part 212 is to interact with the pushing part 220. This interaction can be a simple abutment, or an abutment plus a pulling action. This abutment and pulling action drives the pushing part 220 to move in a predetermined direction, thereby realizing the driving of the pushing part 220. More specifically, the abutment action means that when the acting part 212 rotates to a position in contact with the pushing part 220, continuing to rotate the locking part 210 will cause the acting part 212 to exert a direct thrust on the pushing part 220. This thrust can be perpendicular to the surface of the pushing part 220, or applied at a specific angle, depending on the design of the pushing part 220 and the required movement direction. The abutment action is used to move the pushing part 220 in the direction close to the clamping part 110, so that the distance between the pushing part 220 and the clamping part 110 becomes smaller. The pulling action requires additional mechanical design. For example, the acting part 212 can be designed with a structure that can grasp or latch onto the pushing part 220, and then as the locking part 210 rotates, the acting part 212 pulls the pushing part 220. The pulling action is used to move the pushing part 220 in the direction away from the clamping part 110, so that the distance between the pushing part 220 and the clamping part 110 becomes larger.

[0061] After the pushing part 220 moves to a suitable position, the locking part 210 can lock the pushing part 220 to prevent it from moving during use. Specifically, please refer to Figure 6 , the acting part 212 includes a first part 2121 and a second part 2122. The distance from the first part 2121 to the rotation axis of the locking part 210 is greater than the distance from the second part 2122 to the rotation axis of the locking part 210. In the initial state, the second part 2122 of the locking part 210 abuts against the pushing part 220. At this time, the pushing part 220 is in the first position. When the user needs to adjust the position of the pushing part 220, the locking part 210 can be rotated. As the locking part 210 rotates, the first part 2121 comes into contact with the pushing part 220 and starts to abut against the pushing part 220 to move. Since the first part 2121 is farther from the rotation axis, the first part 2121 can abut against and push the pushing part 220 to displace a certain distance. After the pushing part 220 moves to the second position, the first part 2121 locks the pushing part 220 in the second position. This design realizes the adjustment and locking of the pushing part 220 through a simple rotation action, with simple and stable operation. The user can easily adjust and fix the clamping device without additional tools.

[0062] Please refer to Figure 5, an elastic member 700 is provided between the pushing member 220 and the rod portion 310. The elastic member 700 is used to provide a force for the pushing member 220 to move away from the clamping portion 110. Specifically, when the rod portion 310 is stressed, the rod portion 310 can provide a force for the pushing member 220 to move away from the clamping portion 110 through the elastic member 700, so that the distance between the pushing member 220 and the clamping portion 110 becomes larger. In this design, the acting portion 212 does not need to pull the pushing member 220 to make the distance between the pushing member 220 and the clamping portion 110 larger, thereby simplifying the structure of the acting portion 212. If there is no elastic member 700 between the pushing member 220 and the rod portion 310, it is necessary to pull the pushing member 220 through the acting portion 212 to make the distance between the pushing member 220 and the clamping portion 110 larger.

[0063] Please refer to Figure 6 , the elastic member 700 includes a second spring member 710. One end of the second spring member 710 abuts against the pushing member 220, and the other end of the second spring member 710 abuts against the rod portion 310. Specifically, the second spring member 710 can provide a tension force for the pushing member 220 and the rod portion 310 to move away from each other. When the distance between the pushing member 220 and the clamping portion 110 is the largest, the telescopic connection between the pushing member 220 and the rod portion 310 is in an adjustable state. The second spring member 710 can push the pushing member 220 and the rod portion 310 to be in the maximum extended state. The tension of the second spring member 710 can be transmitted to the tray member 120 through the rod portion 310, so that the tray member 120 and the 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.

[0064] Please refer to Figure 10 , a first spring member 600 is provided between the movable clamping member 400 and the pushing member 220. The movable clamping member 400 and the pushing member 220 are elastically connected through the first spring member 600. The first spring member 600 provides a tension force for the movable clamping member 400 to move in the direction of the abutting portion 130. The movable clamping member 400 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 600 after not being abutted by the abutting portion 130.
