[0046] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0047] Reference Figures 1-4 An adjustable clamping device includes a T-shaped base 1, with two sliding columns 2 slidably connected inside the T-shaped base 1. A rotating column 3 is rotatably connected to each of the two sliding columns 2. A rotating shaft 61 is rotatably connected inside the rotating column 3. A turntable 4 is fixed to the end of the rotating shaft 61. An annular opening 5 is provided on the turntable 4. A sliding rod 6 is slidably connected inside the annular opening 5. A clamping ring 7 is fixed to the end of the sliding rod 6.

[0048] An adjustable clamping device further includes a drive component, a first rotating component, and a second rotating component.

[0049] The driving component facilitates the sliding of the two sliding columns 2 in the same direction. The driving component includes a motor 21 and a double-ended screw 22. The motor 21 is fixed on the T-shaped base 1, and the double-ended screw 22 is fixed on the output end of the motor 21. The sliding column 2 is threadedly connected to the double-ended screw 22.

[0050] The first rotating component drives the rotating column 3 to rotate. The first rotating component includes a transmission component and a limiting component. The transmission component facilitates driving the rotating column 3 to rotate, while the limiting component restricts the rotation of the rotating column 3. The transmission component includes a rotating rod 31, a rocker arm 32, a driving gear 33, a driven gear 34, and a support shaft 35. The rotating rod 31 is rotatably connected to the sliding column 2, the rocker arm 32 is fixed to the rotating rod 31, the driving gear 33 is fixedly sleeved on the rotating rod 31, the driven gear 34 is fixedly sleeved on the rotating column 3, and the support shaft 35 is fixed to the sliding column 2. The driven gear 34 is rotatably connected to the support shaft 35, and the driven gear 34 meshes with the driving gear 33. The rotation of the driving gear 33 is transmitted to the driven gear 34 through the meshing relationship, thereby driving the rotating column 3 to rotate. This gear transmission method has the advantages of smooth transmission and high precision, and can accurately control the rotation angle of the rotating column 3 to meet different clamping requirements.

[0051] The limiting component includes a socket 36 and a pin 37. The socket 36 is formed on the rotating post 3, and the pin 37 passes through the rotating post 3 and is inserted into the socket 36. Multiple sockets 36 are arranged in a circumferential array on the rotating post 3. The pin 37 passes through the rotating post 3 and can be inserted into sockets 36 at different positions. When it is necessary to fix the angle of the rotating post 3, the pin 37 is inserted into the corresponding socket 36 to restrict the rotation of the rotating post 3, ensuring that the position of the rotating post 3 is stable during clamping and will not rotate due to external forces or other factors, thus guaranteeing the reliability of clamping.

[0052] The second rotating component is used to drive the rotating shaft 61 to rotate. The second rotating component includes a synchronous sliding component and a fastener. The synchronous sliding component facilitates the synchronous sliding of multiple sliding rods 6, and the fastener facilitates the restriction of the rotation of the rotating shaft 61.

[0053] The synchronous sliding component includes a handle 62, a collar 63, a support rod 64, and a slider 65. The handle 62 is fixed to the rotating shaft 61, the collar 63 is fixed to the rotating column 3, the support rod 64 is fixed to the outer wall of the collar 63, and the slider 65 is slidably sleeved on the support rod 64. The slider 65 is fixedly connected to the slide rod 6. Four sliders 65 and support rods 64 are provided, corresponding to the number of slide rods 6. The annular opening 5 is also provided corresponding to the number of slide rods 6. When the handle 62 rotates, the collar 63 and support rod 64 drive the slider 65 to slide on the support rod 64, thereby achieving synchronous sliding of multiple slide rods 6. This allows the clamping ring 7 to simultaneously move closer to or further away from the clamped object, achieving a uniform and stable clamping action.

[0054] The fastener includes pin holes 66 and pins 67. Pin holes 66 are formed on the rotating post 3 and the rotating shaft 61. Pins 67 are inserted into the pin holes 66. The pin holes 66 are arranged in a circumferential array, and the outer contour of the pins 67 matches the inner contour of the pin holes 66. When the clamping ring 7 is adjusted to the appropriate clamping position, the pins 67 are inserted into the corresponding pin holes 66 to restrict the rotation of the rotating shaft 61, ensuring that the clamping ring 7 maintains a fixed position and clamping force during clamping, preventing the clamped object from slipping.

[0055] It should be noted that the specific model and specifications of the motor 21 need to be selected and determined according to the actual specifications of the device. The specific selection calculation method adopts the existing technology in this field, so it will not be elaborated here.

[0056] The functional principle of this utility model can be explained through the following operation methods:

[0057] When the motor 21 is started, the output end of the motor 21 drives the double-ended screw 22 to rotate. When the double-ended screw 22 rotates, the two sliding pins 2 located on different thread sections of the double-ended screw 22 will slide in the same direction along the inside of the T-shaped base 1, thereby adjusting the distance between the two sliding pins 2 to accommodate the width of objects of different sizes.

[0058] Rotating the crank 62 causes the rotating shaft 61 to rotate, and the turntable 4 on the rotating shaft 61 rotates accordingly. As the turntable 4 rotates, multiple sliding rods 6 located in the annular opening 5 of the turntable 4 shift with the rotation, and the slider 65 at its bottom slides along the support rod 64. With the cooperation of the slider 65 and the support rod 64, the four sliding rods 6 slide synchronously within the annular opening 5, thereby adjusting the opening and closing degree of the clamping ring 7 to accommodate objects of different shapes and sizes. After the clamping ring 7 is adjusted to the appropriate clamping position, the pin 67 is inserted into the corresponding pin hole 66 on the rotating column 3 and the rotating shaft 61 to restrict the rotation of the rotating shaft 61 and keep the clamping ring 7 in a stable clamping state.

[0059] When the angle of the clamping ring 7 needs to be adjusted, operate the rocker arm 32. The rocker arm 32 drives the rotating rod 31 to rotate, and the driving gear 33 on the rotating rod 31 rotates accordingly and meshes with the driven gear 34. The driven gear 34 drives the rotating column 3 to rotate around the support shaft 35, thereby changing the angle of the clamping ring 7. After adjusting to the appropriate angle, insert the pin 37 into the corresponding insertion hole 36 on the rotating column 3 and the rotating shaft 61 to restrict the rotation of the rotating column 3 and keep the clamping ring 7 at the desired angle.

[0060] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
