At this time, the several teeth 521 of the rotating rod 52 are no longer engaged with the engaging block 62, and the other hand can push the fitting plate 51, and the fitting plate 51 rotates together with the rotating rod 52. The clamping plate 5 is provided with a hole for the rotation of the rotating rod 52, so that the laminating plate 51 is in contact with the surface of the sand and stone. Move up, mesh with the teeth 521 again, complete the position limit of the rotating rod 52, and restrict the engaging block 62 by the inner wall of the mounting block 61, so that the rotating rod 52 cannot continue to rotate, and the fixing of the fitting plate 51 is completed. The bonding plate 51 is always attached to the surface of the sand and gravel to complete the fixation. When disassembling, it is only necessary to turn the screw 31 in the opposite direction, so that the U-shaped rod 3 is affected by the thread between the screw 31 and the threaded hole, and the U-shaped rod 3 is fixed. The distance between the two clamping plates 5 and the two fixed by the connecting block 4 is increased, and the sand and gravel can be disassembled without limiting the position. This solution is more suitable for the sand and gravel with pits and depressions on the surface. , while the fixation is stable, it can also reduce the blocking surface of the sand and gravel, which is more convenient for the detection and use of the sand and gravel.

In Figure 1: both ends of the U-shaped rod 3 penetrate through the bottom wall of the installation table 1, the U-shaped rod 3 is located below the connecting block 4, and a side wall of the U-shaped rod 3 is screwed and fixed with a screw 31, One end is rotatably connected with a rotating block 32, and the rotating block 32 is fixedly connected to the bottom of the installation platform 1. The U-shaped rod 3 is provided with a threaded groove, and the screw rod 31 rotates in the threaded groove opened by the U-shaped rod 3. The rod 3 moves upward due to the influence of the thread between the screw 31 and the thread groove when the screw 31 rotates, so that the positions of the two clamping plates 5 fixed at the upper end of the U-shaped rod 3 gradually move toward the two clamping plates 5 fixed by the connecting block 4. Move to achieve clamping and fixing of sand and gravel.

In Figure 2: the bonding plate 51 is fixedly connected with a bonding layer 511, the bonding layer 511 is made of rubber, and the elastic bonding layer 511 further increases the contact surface between the bonding board 51 and the surface of the sand and gravel, so that the sand and gravel are clamped It can be more stable when held fixed.

In Figure 3: a spring 601 is fixedly connected to the inner wall of the mounting block 61, and the other end of the spring 601 is fixedly connected to the engaging block 62; After the engaging block 62 is lowered in the retracted position, it is no longer engaged with the teeth 521, and the rotating rod 52 can be rotated, so that the bonding plate 51 is in contact with the sand and gravel.

In Figures 1 and 4: the upper end of the installation platform 1 is fixedly connected with a blowing pipe 7, and the blowing pipe 7 is connected with an external fan; At the same time of clamping, the dust remaining on the surface of the sand and gravel and the dust remaining on the surface of the mounting table 1 after clamping can also be cleaned, which is more conducive to the subsequent detection work.

The working principle and use process of the utility model: when in use, the sampled sand and gravel are placed between the two clamping plates 5 fixed by the U-shaped rod 3 and the two clamping plates 5 fixed by the connecting block 4. The threaded rod 3 is provided with a threaded groove, and the screw 31 rotates in the threaded groove opened by the U-shaped rod 3. By rotating the screw 31, the U-shaped rod 3 moves upward due to the influence of the thread between the screw 31 and the threaded groove during rotation. The two clamping plates 5 fixed on the upper end of the U-shaped rod 3 are moved gradually to the positions of the two clamping plates 5 fixed by the connecting block 4, and the distance gradually becomes smaller, until the sand and stone touch the two clamping plates fixed by the connecting block 4. Plate 5, complete the preliminary limit fixation, and then manually press the engaging blocks 62 in the four limiting components 6 to the inside of the mounting block 61, and the spring 601 will elastically deform when the engaging blocks 62 are pressed by the human hand. At this time, the several teeth 521 of the rotating rod 52 are no longer engaged with the engaging block 62, that is, the other hand can push the fitting plate 51, the fitting plate 51 rotates with the rotating rod 52, and the clamping plate 5 is provided with a Rotate the hole through which the rod 52 rotates, so that the bonding plate 51 is in contact with the surface of the gravel. After the contact, the human hand releases it and no longer presses the engaging block 62, so that the spring 601 rebounds and drives the engaging block 62 to move upward, and engages with the teeth 521 again. Intermeshing with each other, the limit of the rotating rod 52 is completed, and the inner wall of the mounting block 61 restricts the engaging block 62, so that the rotating rod 52 cannot continue to rotate, and the fixing of the lamination plate 51 is completed, so that the lamination plate 51 is always in contact with the sand. The surface of the stone is attached and the fixing is completed. When disassembling, it is only necessary to rotate the screw 31 in the opposite direction, so that the U-shaped rod 3 is affected by the thread between the screw 31 and the threaded hole. The distance between the two fixed connecting blocks 4 is increased, and the sand and gravel can be disassembled without limiting the position. This solution is more suitable for the sand and gravel with pits and depressions on the surface. It can reduce the blocking surface of sand and gravel, so as to facilitate the detection and use of sand and gravel.

Finally, it should be noted that the above are only the preferred embodiments of the present invention, and are not intended to limit the present invention. , it is still possible to modify the technical solutions described in the foregoing embodiments, or perform equivalent replacements to some of the technical features. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the present invention shall be included in the protection scope of the present invention.
