If the cable is too thin, the clamp may not effectively clamp it, resulting in improper cable guidance or even damage. Therefore, the lack of adaptive adjustment in cable clamps affects the efficiency and accuracy of 3D scanning and requires further improvement. To address this, a cable clamp for retracting and deploying 3D inspection well scanners has been proposed. Utility Model Content

A semicircular groove 6 is provided at one end of the two fixed blocks 5 that are close to each other. A cable placement area is formed between the two semicircular grooves 6. The two fixed blocks 5 make a linear motion close to each other and complete the cable clamping operation. Specifically, the lower end of the lower fixed block 5 is fixedly connected to the base plate 1, and a bracket 2 is installed on the base plate 1. The front end of the bracket 2 is installed with a top plate 3, and the upper end of the top plate 3 is installed with an electric cylinder 4. The electric cylinder 4 is transmission-connected to the upper fixed block 5. When in use, the bracket 2 is installed on the 3D scanner wire reel frame. After the wire is reeled in, the end of the cable is placed between the two fixed blocks 5. The output end of the electric cylinder 4 is controlled to drive the upper fixed block 5 to move downward to clamp the cable so that the cable will not spread out. However, when fixing cables of other sizes, it is necessary to replace devices of other sizes. The operation is more cumbersome, which increases the cost of use and has a low scope of application.
[0026] In order to solve the above-mentioned drawbacks, two symmetrically arranged slide grooves 9 are opened in the inner wall of the semicircular groove 6 in the horizontal direction. A first fixed plate 7 is slidably assembled in the slide groove 9, and a second fixed plate 8 is slidably assembled inside the fixed block 5 in the vertical direction. By arranging the movable first fixed plate 7 and the second fixed plate 8, the size of the interior of the semicircular groove 6 can be adjusted, so that lines of different sizes can be fixed without replacing other equipment, reducing the cost of use and improving the scope of use of the device.
[0027] On the basis of the above scheme, the adjusting component 12 is provided to drive the two symmetrically arranged first fixing plates 7 to perform relative linear motion, and synchronously drive the second fixing plate 8 to perform linear motion in the vertical direction. Specifically, a second rectangular slot 11 is provided in the interior of the two fixing blocks 5, and a first rectangular slot 10 is provided on the left and right sides of the two second rectangular slots 11. The first rectangular slot 10 is provided in the fixing block 5, and an adjusting component 12 is provided in the two second rectangular slots 11. The two adjusting components 12 are symmetrically distributed up and down; the adjusting component 12 includes a first bevel tooth 121, the first bevel tooth 121 is provided in the second rectangular slot 11, the internal thread of the first bevel tooth 121 is provided with a first screw rod 122, the first bevel tooth 121 is meshed and connected with two second bevel teeth 123 symmetrically distributed on the left and right, the first bevel tooth 121 and the second bevel tooth 123 are of the same size, and a second screw rod 124 is installed at one end of the two second bevel teeth 123 away from each other, and the two second screw rods 124 are respectively movably inserted into the two first rectangular slots 10 on the left and right and movably connected to the inner wall of the first rectangular slot 10, the two The threads of the second screw rods 124 are all threadedly sleeved with connecting plates 126, and the two connecting plates 126 are symmetrically distributed on the left and right. The four first rectangular grooves 10 are respectively connected to the four slide grooves 9, and the connecting plates 126 extend into the slide grooves 9 and are fixedly connected to the first fixed plate 7. The front and rear ends of the connecting plates 126 are respectively slidably connected to the front wall and rear wall of the first rectangular groove 10, and the end of the first screw rod 122 close to the second fixed plate 8 is movably connected to the second fixed plate 8. When in use, it drives the second screw rod 124 on the right to rotate, and the second screw rod 124 on the right side rotates. 24 drives the second bevel tooth 123 on the right to rotate, and the rotation of the second bevel tooth 123 on the right drives the first bevel tooth 121 to rotate. The first bevel tooth 121 drives the second bevel tooth 123 on the left and the second screw rod 124 on the left to rotate. When the two second screw rods 124 rotate, the two connecting plates 126 approach each other and move into the semicircular groove 6. When the first bevel tooth 121 rotates, the first screw rod 122 moves toward the semicircular groove 6, driving the second fixing plate 8 to move synchronously into the semicircular groove 6, so that the size of the cable fixing area of the semicircular groove 6 changes.
[0028] In order to support the rotation of the first bevel gear 121 , the outer surface of the first bevel gear 121 is movably sleeved on the support plate 13 , and the support plate 13 is installed on the second rectangular groove 11 through a screw.

[0031] In addition, in order to be able to quickly adjust the size of the fixed line area of the semicircular groove 6, a moving rod 14 is installed at the right end of the right connecting plate 126. The moving rod 14 is movably inserted into the right side of the fixed block 5 and fixedly connected to the limiting block 15. The outer surface of the moving rod 14 is provided with scale lines. According to the radius of the cable, the radius of the cable is subtracted from the radius of the semicircular groove 6 to obtain the value to be adjusted. When the adjusting component 12 is rotated, the connecting plate 126 drives the moving rod 14 to move, so that the value on the scale line on the moving rod 14 is the same as the value subtracted from the radius of the cable and the semicircular groove 6, thereby accurately adjusting the distance required to move the first fixed plate 7 and the second fixed plate 8 without repeated adjustments, reducing the time for later adjustments and improving work efficiency.
