[0032] Inside the fastening bracket 2, the support frame 21, support column 24, and top plate 23 form a whole. The limiting groove 22 opened in the support frame 21 can cooperate with the support component 3 to provide support for the support component 3. At the same time, the top plate 23 and support column 24 are also equipped with lifting plate 25 and pressure spring 26. This allows the top baffle 5 to contact the top of the object to be fastened, and the top baffle 5 and lifting plate 25 to move upward to compress the pressure spring 26 and form a pressure to stabilize the object to be fastened. When it is necessary to put the object to be fastened in, the screws connecting the top baffle 5 and lifting plate 25 can be removed, the top baffle 5 can be removed, the object can be put in, and then the top baffle 5 and lifting plate 25 can be connected and fixed.

[0033] In this embodiment, the support component 3 includes a threaded block 31, a positioning block 33, and a limiting slider 36. The threaded block 31, the positioning block 33, and the limiting slider 36 are all slidably connected to the inner wall of the support frame 21 through adjacent limiting grooves 22. The output shaft of the threaded block 31 is connected to a threaded sleeve 35 through a coupling. The threaded sleeve 35 is rotatably connected to the inner wall of the positioning block 33. A first screw 34 is threadedly connected to the threaded sleeve 35. The first screw 34 is fixedly connected to the adjacent contact plate 4. A limiting slider 36 is slidably connected to a limiting slider 37. The limiting slider 37 is fixedly connected to the adjacent contact plate 4. The support component 3 also includes a second servo motor 38. The output shaft of the second servo motor 38 is connected to a second screw 39 through a coupling. A threaded block 31 is threadedly connected to the second screw 39. The threaded block 31 is connected to the first servo motor 32. The top end of the second screw 39 is rotatably connected to the inner wall of the fastening bracket 2.

[0034] In this embodiment, the contact plate 4 includes two support plates 41. A connecting block 43 is installed on one side of the two adjacent support plates 41. The two connecting blocks 43 are fixed by screws. Both support plates 41 are arc-shaped, and a contact pad 42 is installed on both support plates 41.

[0035] How to use and how to work this device:

[0036] When in use, the device is surrounded by a ring consisting of a fastening bracket 2, a support component 3, a contact plate 4, and a top baffle 5. This provides secure protection for items placed on the vibrating table body 1, preventing the equipment or items from falling off the vibrating table body 1.

[0037] Inside the main body 1 of the vibration table, the table surface 11, the support legs 13, and the base 14 cooperate to form the main body. A vibration motor 12 is added to this main body to make the main body 1 of the vibration table into a main body that can actively generate vibration.

[0038] Inside the fastening bracket 2, the support frame 21, support column 24, and top plate 23 form a whole. The limiting groove 22 opened in the support frame 21 can cooperate with the support component 3 to provide support for the support component 3. At the same time, the top plate 23 and support column 24 are also equipped with lifting plate 25 and pressure spring 26. This allows the top baffle 5 to contact the top of the object to be fastened, and the lifting plate 25 to move upward to compress the pressure spring 26 to form a pressure stabilizing force on the object to be fastened. When it is necessary to put the object to be fastened in, the screws connecting the top baffle 5 and the lifting plate 25 can be removed, the top baffle 5 can be removed, the object can be put in, and then the top baffle 5 and the lifting plate 25 can be connected and fixed.

[0039] Within the support assembly 3, the threaded block 31, the second screw 39, and the second servo motor 38 form an initial support effect. After the first servo motor 32 is connected to the positioning block 33, the rotation of the second screw 39 driven by the second servo motor 38, under the limitation of the first servo motor 32 and the positioning block 33, can drive the threaded block 31 to rise and fall, which correspondingly drives the contact plate 4 to rise and fall. When it is necessary to adjust the distance between the contact plate 4 and the object to be fastened, it is only necessary to start the first servo motor 32 to drive the threaded sleeve 35 in the positioning block 33 to rotate, and the first screw 34 is fixedly connected to the contact plate 4. Furthermore, the contact plate 4 is connected to the limiting slide bar 37 via the limiting slider 36, which can limit the rotation of the first screw 34. Thus, the rotation of the threaded sleeve 35 will cause the first screw 34 to extend or retract from the threaded sleeve 35, allowing the contact plate 4 to move closer to or further away from the object to be fastened, forming a loose or tight enclosure. The limiting slide bar 37 slides in correspondence with the limiting slider 36, improving the overall stability of the movement of the contact plate 4. Moreover, when the first servo motor 32 drives the contact plate 4 to rise and fall, the sliding connection between the limiting slider 36, the positioning block 33, and the limiting slide groove 22 can also improve the overall stability of the movement.

[0040] Inside the contact plate 4, the contact pad 42 replaces the support plate 41 to prevent scratches or other objects from being placed on the surface to be fastened, while the connecting block 43 can establish a connection between the two support plates 41. When disassembly is required, the connection between the two support plates 41 can be released simply by removing the screws, which is convenient for maintenance or replacement.

[0041] The above are merely preferred embodiments of this utility model and are not intended to limit the utility model in any other way. Any person skilled in the art may make changes or modifications to the above-disclosed technical content to create equivalent embodiments for application in other fields. However, any simple modifications, equivalent changes, and modifications made to the above embodiments based on the technical essence of this utility model without departing from the technical solution of this utility model shall still fall within the protection scope of this utility model.
