DETAILED DESCRIPTION

[0029] The following will be combined with the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

In the U"-shaped structure, the L-shaped support plate 211 and the telescopic bottom plate 212 are both in contact with the operating table 1, and a connecting rod 2121 is provided on the side of the telescopic bottom plate 212 facing the L-shaped support plate 211, and the connecting rod 2121 is embedded in the L-shaped support plate 211. A tightening structure for moving the telescopic bottom plate 212 toward the L-shaped support plate 211 through the connecting rod 2121 is provided in the L-shaped support plate 211, and a rotating handle 23 for facilitating the operator to rotate the tightening structure is embedded in the tightening structure, and the rotating handle 23 extends in a direction away from the operating table 1 and extends out of the L-shaped support plate 211.

[0031] The operating table 1 provides a stable working platform for installing and supporting the clamp body 2. The clamp body 2 is used to clamp and fix the raw material to keep it stable during the processing, improve the processing accuracy, and prevent the raw material from moving or loosening. The sliding connection between the clamp body 2 and the operating table 1 allows the clamp body 2 to slide on the operating table 1 to adjust the position and adapt to raw materials of different sizes, thereby enhancing the flexibility of the clamp, enabling quick position adjustment, and improving production efficiency. The L-shaped support plate 211 provides a fixed base, which ensures the stability of the clamp body 2 by connecting to the edge of the operating table 1. The telescopic bottom plate 212 cooperates with the L-shaped support plate 211 to form a "U"-shaped structure to clamp the edge of the operating table 1. The combination of the L-shaped support plate 211 and the telescopic bottom plate 212 provides an adjustable clamping method to adapt to the edges of the operating table 1 of different thicknesses. The connecting rod 2121 is used to connect the telescopic base plate 212 with the L-shaped support plate 211, and transmit the force of the tightening structure to ensure that the telescopic base plate 212 moves toward the L-shaped support plate 211 during the tightening process to achieve clamping. The tightening structure rotates to move the telescopic base plate 212 toward the L-shaped support plate 211 to clamp the edge of the operating table 1, which simplifies the clamping steps. The operator only needs to rotate to complete the clamping, thereby improving the installation efficiency. The rotating handle 23 facilitates the operator to rotate the tightening structure to achieve the clamping operation; the end of the rotating handle 23 away from the L-shaped support plate 211 should be provided with an extension or protrusion for facilitating the operator to rotate the rotating handle 23, and the size of the extension or protrusion should be adjusted according to the actual rotation strength to make it easier to rotate.

[0032] In this embodiment, the tightening structure includes a first rotating disk 24 and a limiting groove body. The first rotating disk 24 is located in the L-shaped support plate 211 and is rotatably connected to the L-shaped support plate 211.

A first annular groove 241 is provided on the side of the first rotating disk 24. A contraction rope 2122 is provided in the first annular groove 241. The two ends of the contraction rope 2122 are respectively fixedly connected to the first rotating disk 24 and the connecting rod 2121.

The cross-section of the middle groove 2111 is the same as the cross-section structure of the rotating handle 23, and the cross-section of the fixed groove 2112 is the same as the cross-section structure of the first limiting side plate 231. One end of the rotating handle 23 is located in the middle groove 2111, and the first limiting side plate 231 is located in the first rotating disk 24 and one of the fixed grooves 2112.

[0033] The first rotating disk 24 is used to generate tension on the retractable rope 2122 by rotating, thereby pulling the connecting rod 2121 to move, thereby achieving the tightening or loosening of the telescopic bottom plate 212 and the L-shaped support plate 211. The first annular groove 241 is used to accommodate the retractable rope 2122. The retractable rope 2122 is used to cooperate with the rotation of the first rotating disk 24 to move the connecting rod 2121, thereby achieving the conversion from rotational motion to linear motion, simplifying the structure of the clamping mechanism and improving the clamping efficiency; the retractable rope 2122 can be a steel wire rope, which has the characteristics of light weight, high strength, good elasticity, ability to withstand impact loads, and good winding properties. The limiting groove body is used to limit the position and rotation angle of the rotating handle 23, and limit the rotation of the first rotating disk 24 after the L-shaped support plate 211 and the telescopic bottom plate 212 clamp the operating table 1, so as to prevent the L-shaped support plate 211 and the telescopic bottom plate 212 from loosening, resulting in an unstable connection between the clamp body 2 and the operating table 1. The sliding connection between the rotating handle 23 and the first rotating disk 24 enables the rotating handle 23 to move inside the first rotating disk 24, thereby realizing the first limiting side plate 231 to move between the first rotating disk 24 and the limiting groove body, thereby achieving the function of the rotating handle 23 driving the first rotating disk 24 to move and the limiting groove body to limit the rotation of the first rotating disk 24. The first limiting side plate 231 is used to assist the rotating handle 23 in rotating the first rotating disk 24, thereby enabling the rotating handle 23 to stably rotate the first rotating disk 24, and cooperate with the limiting groove body to limit the rotation of the first rotating disk 24, thereby maintaining the clamping state of the L-shaped support plate 211 and the telescopic bottom plate 212.

The fixed block 234 is used to fix the rotating handle 23 through the sliding connection and the buckle 236 mechanism, thereby enhancing the stability of the rotating handle 23. The return spring 235 is used to provide elastic force to automatically return the fixed block 234, ensure that the fixed block 234 can automatically return to the initial position after use, and ensure the stable fixation of the rotating handle 23. The buckle 236 and the annular groove 2114 are used to fix the rotating handle 23. The annular groove 2114 can ensure that the buckle 236 can still be connected and fixed with the annular groove 2114 when the rotating handle 23 is rotated to any angle.

[0035] The working process of the clamping structure 21 is as follows: insert the "U"-shaped structure composed of the L-shaped support plate 211 and the telescopic bottom plate 212 into the edge of the operating table 1, so that the edge of the operating table 1 is located between the L-shaped support plate 211 and the telescopic bottom plate 212; pull the rotating handle 23 to move away from the operating table 1, so that the first limiting side plate 231 is only connected to the first rotating disk 24; turn the rotating handle 23, the rotating handle 23 drives the first rotating disk 24 to rotate, the retraction rope 2122 is tightened, and then the connecting rod 2121 is pulled toward the L-shaped support plate 211, so that the telescopic bottom plate 212 moves toward the L-shaped support plate 211, so that the L-shaped support plate 211 and the telescopic bottom plate 212 clamp the operating table 1; after clamping, push the rotating handle 23 toward the operating table 1, so that the first limiting side plate 231 is connected to the first rotating disk 24 and the limiting groove body at the same time, the anti-slip pad abuts against the operating table 1, and the buckle 236 is embedded in the annular groove 2114 and fixed.
