[0020] The preferred embodiments of the present utility model will be described below in conjunction with the accompanying drawings. It should be understood that the preferred embodiments described herein are only used to illustrate and explain the present utility model, and are not used to limit the present utility model.

[0021] Embodiment: As Figure 1-2 shown, the present utility model provides a technical solution, a slate clip with high safety, including a first frame 1 and a second frame 2. The first frame 1 is cross-mounted on one side edge of the second frame 2. The first frame 1 and the second frame 2 are in an L shape, which is convenient for clamping. The edge parts of the first frame 1 and the second frame 2 are provided with limiting holes 3 at equal distances. The edge parts of the first frame 1 and the second frame 2 are provided with five limiting holes 3, which is convenient for adjustment. A rotating bolt 4 is installed in the limiting holes 3 at the intersection position of the first frame 1 and the second frame 2;

[0022] The rotating bolt 4 is installed through the interiors of the first frame 1 and the second frame 2. The rotating bolt 4 is installed in the interiors of the first frame 1 and the second frame 2 through nuts, which is convenient for fixing. A rotating block 5 is rotatably installed at the bottom of the first frame 1 and the second frame 2;

[0023] A clamping plate 6 is installed on one side of the rotating block 5. The surface of one side of the clamping plate 6 is provided with a rough surface to increase the friction force. The clamping plate 6 is installed at one end of the rotating block 5 through a connecting rotating seat. The rotating block 5 is rotatably connected to the bottom of the first frame 1 and the second frame 2 through a rotating column, which is convenient for fitting with the surface of the clamped item. A rotating connection lock 7 is installed at the top of the first frame 1 and the second frame 2. One end of the rotating connection lock 7 is rotatably installed on the first frame 1, and the other end is installed with a chain 8, which is convenient for transmission. One end of the chain 8 is connected to the rotating connection lock 7 away from the first frame 1 and the second frame 2. A buckle lock 9 is installed in the middle of the chain 8. The buckle lock 9 is in a U-shaped structure. A threaded hole is penetrated at one end of the buckle lock 9, and a bolt is installed in the threaded hole through a fixing nut, which is convenient for fixing.

[0024] The working principle and usage process of the present utility model: First, the staff unscrews the bolt nut installed at one end of the buckle lock 9, sleeved the buckle lock 9 on the position of the grab hook of the excavator, and then reinstalls the bolt nut to limit the position of the buckle lock 9. After fixing the buckle lock 9, the staff adjusts the opening and closing width of the first frame 1 and the second frame 2 according to the size of the item to be clamped, and adjusts it by installing the rotating bolt 4 into different limiting holes 3 at the intersection position of the first frame 1 and the second frame 2;
