[0023] In order to make the purpose, technical solutions and advantages of the present invention more apparent, the following exemplary embodiments of the present invention will be described in detail with reference to the accompanying drawings. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments of the present invention. It should be understood that the present invention is not limited to the exemplary embodiments described herein. Based on the embodiments of the present invention described in this utility model, all other embodiments obtained by those skilled in the art without creative work should fall within the scope of protection of the present utility model.

[0024] In the following description, numerous details are provided to facilitate a thorough understanding of the present invention. However, those skilled in the art will appreciate that the following description merely illustrates preferred embodiments of the present invention, and that the present invention may be practiced without one or more of these details. Furthermore, to avoid confusion with the present invention, some technical features well known in the art have not been described in detail.

[0025] To thoroughly understand the embodiments of the present invention, a detailed structure will be provided in the following description. Obviously, the implementation of the embodiments of the present invention is not limited to the specific details familiar to those skilled in the art. Preferred embodiments of the present invention are described in detail below, but in addition to these detailed descriptions, the present invention may also have other embodiments.

[0026] In one embodiment of the present invention, a clamping mechanism is provided, which can ensure that the object 3 to be clamped is firmly clamped and effectively prevent the object 3 from falling off during the clamping process. A clamping mechanism according to an embodiment of the present invention will be described in detail below with reference to the accompanying drawings.

[0027] See Figure 1 The clamping mechanism includes a driving member 1 and a plurality of clamping members 2. The plurality of clamping members 2 are respectively connected to the driving member 1 and can be switched between a clamping state and a release state by the driving member 1. The clamping members 2 have a clamping side facing the object 3 to be clamped and are provided with a spike portion 21 on the clamping side. The spike portion 21 penetrates into the wall of the object 3 to be clamped when the clamping member 2 is in the clamping state.

[0028] The driving member 1 can drive the plurality of clamping members 2 to move closer to or farther away from each other. When the plurality of clamping members 2 move closer to each other, the sharp portions 21 of the clamping members 2 abut and penetrate into the wall of the object 3 to be clamped, and at this time, the clamping members 2 are in a clamped state. When the plurality of clamping members 2 move farther away from each other, the sharp portions 21 of the clamping members 2 are separated from the wall of the object 3 to be clamped, and at this time, the clamping members 2 are in a released state.

[0029] The material of the side wall of the object 3 to be clamped can be a non-metallic material, such as plastic, rubber, etc., and is preferably plastic.

[0030] The sharp portion 21 can be conical or can be a conical structure composed of four triangular planes. Taking the sharp portion 21 as an example of a conical structure composed of four triangular planes, the machining of a plurality of sharp portions 21 can be completed at one time using a machining tool, effectively reducing the machining difficulty of the sharp portion 21. The machining tool can be a turning tool, etc.

[0031] In the above embodiment, when the object 3 to be clamped is clamped by the clamping members 2, the sharp portions 21 on the clamping members 2 can penetrate into the side wall of the object 3 to be clamped. When facing different shapes of the object 3 to be clamped, the clamping mechanism can firmly clamp the object 3 to be clamped, effectively avoiding the occurrence of situations such as falling off and overturning of the object 3 to be clamped during clamping, and improving the practicality and reliability of the clamping mechanism.

[0032] In some embodiments, referring to Figure 2 The sharp portion 21 on each clamping member 2 is a plurality of sharp portions 21, and the plurality of sharp portions 21 are arranged on the clamping side at a predetermined interval.

[0033] The user can determine the number of sharp portions 21 according to the weight of the object 3 to be clamped.

[0034] For example, when the object 3 to be clamped is light in weight, the number of sharp portions 21 can be two, and the two sharp portions 21 can be arranged at the ends of the clamping side. When the object 3 to be clamped is heavy in weight, the number of sharp portions 21 can be a plurality, and the plurality of sharp portions 21 can be arranged on the clamping side along the length direction of the clamping member 2.

[0035] In the above embodiment, by arranging a plurality of sharp portions 21 on the clamping side, the connection points between the clamping member 2 and the object 3 to be clamped can be increased, so that the connection between the two is more secure, effectively improving the safety and reliability of the clamping mechanism.

[0036] In some embodiments, the sharp portion 21 on each clamping member 2 is at least eight, and the at least eight sharp portions 21 are divided into at least two sharp groups, each sharp group having at least four sharp portions 21, and the at least two sharp groups are arranged on the clamping side at a predetermined interval.

[0037] The at least two spike groups arranged at predetermined intervals allow the clamping member 2 to better adapt to objects 3 of varying sizes and shapes, ensuring a more reliable and durable grip during the clamping process. Furthermore, the spike groups arranged at predetermined intervals make the clamping member 2 more versatile, providing a higher gripping capability for non-uniform or irregularly shaped objects 3.

[0038] In the above embodiment, at least two spike groups arranged at preset intervals can evenly distribute the clamping force on the object to be clamped 3, making the clamping process more stable and reliable, adapting to a wider range of clamping needs, and improving the efficiency, safety and reliability of the operation.

[0039] In some embodiments, see Figure 3 The clamping mechanism also includes a mounting member 4 , and the driving member 1 is connected to each clamping member 2 through the mounting member 4 , and the clamping member 2 is arranged on at least one side of the mounting member 4 .

[0040] The two ends of the mounting member 4 are respectively connected to the driving member 1 and the clamping member 2. The mounting member 4 can be rod-shaped, and one end of the rod-shaped mounting member 4 can be arranged above or below the clamping member 2. This application does not impose any restrictions on this.

[0041] In the above embodiment, the contact area between the clamping mechanism and the object to be clamped 3 can be further increased by the mounting member 4 to ensure firmness during the clamping process, thereby effectively improving the reliability of the clamping mechanism.

[0042] In some embodiments, see Figure 3 The clamping mechanism also includes a rotating shaft 5, and the mounting member 4 is rotatably connected to the clamping member 2 via the rotating shaft 5.

[0043] A portion of the rotating shaft 5 is passed through the mounting member 4, and another portion of the rotating shaft 5 is passed through the clamping member 2. In this way, the clamping member 2 can rotate circumferentially around the rotating shaft 5 to meet the clamping needs of objects 3 to be clamped of different shapes.

[0044] For example, the outer wall of the object to be clamped 3 is inclined. When the clamping operation is performed using the clamping mechanism, the clamping member 2 can deflect according to the shape of the outer wall of the object to be clamped 3, so that the clamping member 2 can be in close contact with the object to be clamped 3 and firmly penetrate the side wall of the object to be clamped 3.

[0045] In the above embodiment, the rotating shaft 5 can enable the clamping member 2 to have a larger rotation direction, so that the clamping mechanism can be applicable to objects 3 to be clamped with different outer wall shapes, effectively improving the universality and flexibility of the clamping mechanism.

[0046] In some embodiments, see Figure 3The clamping mechanism further includes a limiting shaft 6, which passes through the mounting member 4 and the clamping member 2, and forms a spacing cavity 7 with the mounting member 4 and the clamping member 2 respectively.

[0047] One end of the limiting shaft 6 passes through the mounting member 4 and is arranged in the clamping member 2, and a gap is formed between the limiting shaft 6 and the mounting member 4 and the clamping member 2 respectively, so as to ensure that the clamping member 2 can rotate at a small angle while avoiding the situation where the clamping cannot be clamped due to excessive rotation angle.

[0048] For example, when the clamping mechanism is not provided with a limit shaft 6, the clamping member 2 can freely rotate circumferentially about the rotation axis 5. During the process of the clamping mechanism moving toward the object 3 to be clamped, the clamping side of the clamping member 2 may rotate away from the object 3 to be clamped, thus preventing the clamping mechanism from smoothly clamping the object 3. However, the limit shaft 6 can ensure that the clamping side of the clamping member 2 always faces the object 3 to be clamped, thereby ensuring that the clamping mechanism can smoothly clamp the object 3.

[0049] In the above embodiment, the limiting shaft 6 can ensure that the clamping member 2 can rotate while the clamping side of the clamping member 2 is directed toward the object to be clamped 3, effectively ensuring the reliability and practicality of the clamping mechanism.

[0050] In some embodiments, see Figure 3 There are multiple limiting shafts 6, and the multiple limiting shafts 6 are arranged on opposite sides of the rotating shaft 5.

[0051] In the above embodiment, multiple limiting shafts 6 can improve the stability of the clamping mechanism and reduce the load of each limiting shaft 6, thereby increasing the load capacity of the entire clamping mechanism and further improving the reliability and practicality of the clamping mechanism.

[0052] In some embodiments, the axis of the limiting shaft 6 forms an angle with the axis of the rotating shaft 5 , and the angle is an acute angle.

[0053] The rotating shaft 5 can be arranged in the vertical direction, and an acute angle can be formed between the axis of the limiting shaft 6 and the axis of the rotating shaft 5. When the clamping member 2 rotates, the limiting shaft 6 can abut against the spacing cavity 7, which can effectively reduce the rotation angle of the clamping member 2.

[0054] In the above embodiment, the rotating shaft 5 with a certain inclination angle can limit the rotation angle of the clamping member 2. In this way, the rotation of the clamping member 2 is ensured while avoiding the situation where the clamping mechanism cannot clamp smoothly due to excessive rotation angle, thereby effectively improving the clamping efficiency and practicality of the clamping mechanism.

[0055] In some embodiments, see Figure 4 The angle of the spike portion 21 ranges from 40 degrees to 50 degrees.

[0056] The value range of the sharp angle is 40 degrees to 50 degrees (°), for example, 40°, 42°, 45°, 47°, 50°, preferably 45°.

[0057] In the above embodiment, the spike portion 21 with the above-mentioned sharp angle can enable the clamping member 2 to quickly penetrate into the side wall of the object to be clamped 3 when the clamping member 2 is in the clamping state, and when the clamping member 2 is in the loosened state, the spike portion 21 can smoothly separate from the object to be clamped 3, thereby further improving the practicality and reliability of the clamping mechanism.

[0058] Another embodiment of the present invention provides a transport device including the clamping mechanism as described above.

[0059] The transport device of the present invention includes the clamping mechanism as described above. Since the clamping mechanism has the beneficial effects as described above, the transport device including the clamping mechanism must also have the beneficial effects as described above.
