[0002] Common structures of clamping and fixing devices include components such as mounting base, jaws, and drive shaft, which achieve precise positioning and fixing through bevel gears and adjusting bolts.

[0003] Currently, existing clamping and fixing devices cannot achieve the function of locking on and off. After adjusting the clamping, it is necessary to operate again to lock the clamping device before it can clamp and fix the item, which is quite troublesome.

[0004] Therefore, we propose a clamping and fixing device that can be adjusted and locked simultaneously. Utility Model Content

[0016] To make the above-mentioned objectives, features and advantages of this utility model more readily understood, the specific embodiments of this utility model will be described in detail below with reference to the accompanying drawings.

[0017] Many specific details are set forth in the following description in order to provide a full understanding of the present invention. However, the present invention may also be implemented in other ways different from those described herein. Those skilled in the art can make similar extensions without departing from the spirit of the present invention. Therefore, the present invention is not limited to the specific embodiments disclosed below.

[0018] Secondly, the term "an embodiment" or "embodiment" as used herein refers to a specific feature, structure, or characteristic that may be included in at least one implementation of the present invention. The phrase "in one embodiment" appearing in different places in this specification does not necessarily refer to the same embodiment, nor is it a single embodiment or an embodiment selectively excluded from other embodiments.

[0019] Example 1: Please see Figure 1 - Figure 5 This is the first embodiment of the present invention. This utility model provides a clamping and fixing device that can be adjusted and locked simultaneously, including: a base 1, a connecting column 2 fixedly connected to the base 1, a fixing plate 3 fixedly connected to the end of the connecting column 2, three sets of sliding grooves 4 opened on the fixing plate 3, a sliding column 5 slidably connected in the sliding grooves 4, a pressing block 6 fixedly connected to the end of the sliding column 5, a rotating plate 7 rotatably connected to the outer side of the connecting column 2, three sets of inclined grooves 8 opened on the rotating plate 7, the inclined grooves 8 being adapted to the sliding column 5, and a self-locking mechanism 9 installed between the rotating plate 7 and the base 1.

[0020] The end of the compression block 6 is equipped with a sponge pad 24 to avoid rigid compression of the item, thereby protecting the clamped item.

[0021] It should be noted that the rotation of the rotating disk 7 causes the inclined groove 8, the sliding column 5, and the sliding groove 4 to cooperate, so that the sliding column 5 drives the squeezing block 6 to move, thereby clamping and fixing the item. During this process, self-locking is achieved through the action of the self-locking mechanism 9.

[0022] In the embodiments of this utility model, please refer to Figure 2 and Figure 4 The self-locking mechanism 9 shown in the figure includes a fixing block 10 sleeved on the outer side of the connecting column 2. The fixing block 10 is fixedly connected to the base 1, and a rotating ring 11 is rotatably connected to the outer side of the fixing block 10. The rotating ring 11 is fixedly connected to the rotating disk 7, and a limiting member 25 is installed inside the fixing block 10.

[0023] The limiting member 25 includes a spring 12 fixed inside the fixing block 10. The end of the spring 12 is fixedly connected to a movable column 13 that is slidably connected to the fixing block 10. The end of the movable column 13 is rotatably connected to a ball 14. The rotating ring 11 is provided with a groove 15 that is adapted to the ball 14. Multiple sets of grooves 15 are provided and are arranged in a circumferentially close arrangement. The other end of the sliding column 5 is equipped with a fastener 16.

[0024] Example 2: Please see Figure 1 - Figure 5 This is the second embodiment of the present invention. In the embodiments of this utility model, please refer to Figure 4 and Figure 5 The fastener 16 shown in the figure includes a connecting rod 17 fixedly connected to the movable column 13. The connecting rod 17 is slidably connected to the fixed block 10, and a limiting block 18 slidably connected to the fixed block 10 is installed at the end of the connecting rod 17. A threaded sleeve 19 slidably connected to the base 1 is fixedly connected to the limiting block 18. A movable part 26 for driving the threaded sleeve 19 to move is installed inside the threaded sleeve 19.

[0025] The movable component 26 includes a threaded rod 20 that is threadedly connected to the threaded sleeve 19. The threaded rod 20 is rotatably connected to the base 1, and a rotating rod 21 is fixedly connected to the threaded rod 20. The rotating rod 21 is slidably connected to the base 1, and the base 1 has an active groove 23 that is adapted to the rotating rod 21.

[0026] In addition, an operating block 22 is fixedly connected to the end of the rotating rod 21 to facilitate the rotation of the rotating rod 21.

[0027] Working principle: By rotating the rotating disk 7, the inclined groove 8 and the sliding column 5 are engaged, causing the sliding column 5 to slide inside the sliding groove 4. This causes the sliding column 5 to drive the pressing block 6 to slide, and the pressing block 6 to press the item. During this process, the rotation of the rotating disk 7 will drive the rotating ring 11 to rotate, and the rotation of the rotating ring 11 will cause the rolling groove 15 to rotate. During the rotation, the ball 14 will compress the spring 12 and retract into the fixed block 10. After the rotating disk 7 stops rotating, the ball 14 will be pushed into the rolling groove 15 by the action of the spring 12, thereby achieving the self-locking limit of the rotating ring 11 and the rotating disk 7. Furthermore, after the item is clamped and fixed, the rotating rod 21 is rotated by the action of the operating block 22. The rotation of the rotating rod 21 causes the threaded rod 20 to rotate, and the rotation of the threaded rod 20 causes the threaded sleeve 19 to move. This causes the limiting block 18 to move up to one side of the connecting rod 17. At this time, due to the compression of the connecting rod 17 by the limiting block 18, the connecting rod 17 cannot move, and the sliding column 5 cannot move. At this time, the ball 14 will not be able to slide inside the groove 15, and the rotating disk 7 will not be able to rotate, thus realizing the self-locking of the device and the stability of the structure.

Although only a few embodiments are described in detail in this disclosure, those who consult this disclosure will readily understand that many modifications are possible (e.g., changes in the size, dimensions, structure, shape, and proportions of various elements, as well as parameter values ​​(e.g., temperature, pressure, etc.), mounting arrangements, use of materials, color, orientation, etc.) without substantially departing from the novel teachings and advantages of the subject matter described in this application). For example, an element shown as integrally formed may be composed of multiple parts or elements, the position of elements may be inverted or otherwise altered, and the nature or number or position of discrete elements may be changed or altered.
