[0025] This invention addresses the problem that fixtures are inconvenient for fine adjustments, and operators cannot adjust the clamping position according to the characteristics of the test material, thus reducing the accuracy and reliability of testing. It provides a solution such as… Figures 1-3 The manual clamping tool for pull-out testing shown includes a base 1, a fixed frame 2 fixedly connected to the top surface of the base 1, a first groove 21 opened on the side wall of the fixed frame 2, a first slider 22 slidably disposed inside the first groove 21, a moving block 41 slidably disposed on the side wall of the first slider 22, and a fixed block 4 fixedly connected to the bottom of the fixed frame 2 near the moving block 41; when performing a pull-out test, the material to be tested is installed on the fixed block 4 and the moving block 41.

[0026] In this utility model, an electric cylinder 25 is fixedly connected to the top surface of the fixed frame 2, and a connecting block 23 is fixedly connected to the top side wall of the first slider 22. The piston rod end of the electric cylinder 25 passes through the fixed frame 2 and is fixedly connected to the top surface of the connecting block 23. When a pull-out test is performed, the electric cylinder 25 is turned on, and the electric cylinder 25 drives the connecting block 23 to move up and down. The connecting block 23 drives the first slider 22 to move in the first slide groove 21.

[0027] In this invention, a first bevel gear 33 and a second bevel gear 34 are provided at the top of the second slide groove 3. The top end of the first lead screw 32 passes through the second slide groove 3 and is fixedly connected to the first bevel gear 33. A rotating rod 35 is provided on the side wall of the first slider 22. The rotating rod 35 passes through the first slider 22 and is fixedly connected to the second bevel gear 34. The first bevel gear 33 and the second bevel gear 34 are meshed together. When adjusting the moving block 41, rotating the rotating rod 35 causes the second bevel gear 34 to rotate, which in turn causes the first bevel gear 33 to rotate. The first bevel gear 33 then causes the first lead screw 32 to rotate, which in turn causes the second slider 31 to move. The movement of the second slider 31 then causes the moving block 41 to move, thereby completing the adjustment.

[0028] It should be noted that the first slider 22 has a second slide groove 3 on its side wall, and the second slider 31 is slidably connected inside the second slide groove 3. The side wall of the second slider 31 is fixedly connected to the side wall of the moving block 41. The first lead screw 32 is rotatably installed inside the second slide groove 3. The second slider 31 has a threaded hole, and the first lead screw 32 is connected to the threaded hole. When fine adjustments are needed, the first lead screw 32 is rotated, and the rotation of the first lead screw 32 drives the second slider 31 to move within the second slide groove 3, thereby completing the adjustment.

[0029] During the pull-out test, the first slider 22 is moved by the cooperation of the components. The movement of the first slider 22 drives the moving block 41 to move. The movement of the moving block 41 drives the test material to move upward, thereby completing the pull-out test. When fine adjustments are needed, the moving block 41 can also be moved manually to complete more precise adjustments.

[0030] The height of the moving block 41 can be manually and finely adjusted, allowing operators to flexibly set the clamping position according to specific test requirements and material properties, which helps to improve the accuracy and reliability of the test.

[0031] By manually making slight adjustments to the height of the moving block 41, the operator can also indirectly adjust the clamping force of the moving block 41 on the test material, ensuring that the test material will not slip or move during the pulling process, and at the same time, the test material will not be damaged due to excessive clamping force.

[0032] Through precise manual adjustment, the operator can adjust the moving block 41 to the optimal position in one go, reducing test interruptions caused by repeated adjustments. At the same time, manually adjusting the height of the moving block 41 can prevent damage to the moving block 41 due to excessive stroke.

[0033] Furthermore, both the fixed block 4 and the moving block 41 have clamping grooves 42 in the middle. Clamping plates 43 are slidably arranged on both sides inside the clamping grooves 42. The two clamping plates 43 located on the same plane are symmetrically arranged. The two clamping plates 43 located on the same plane have triangular grooves 45 and wavy grooves 44 on the side close to each other. When clamping, the material is placed in the wavy groove 44 or the triangular groove 45 according to the test material. Due to the combination of the openings of the wavy groove 44 and the triangular groove 45 in the clamping plate 43, the clamping plate 43 can adapt to test materials of different shapes and sizes, which improves the versatility and practicality of the clamping plate 43 and enables it to be used in a variety of different pull-out tests.

[0034] It should be noted that the triangular groove 45 has a stable structure and good clamping effect, and is suitable for tensile testing of hard or special materials, such as metals, plastics, rubber, etc., as well as some specimens that require special clamping methods. The wavy groove 44 has a soft tooth shape and is particularly suitable for tensile testing of soft strip materials, such as cloth and leather materials, woven strips, etc. The wavy groove 44 can also effectively prevent the test material from being damaged during the clamping process.

[0035] In this invention, a second lead screw 46 is provided on both sides of the fixed block 4 and the movable block 41. A threaded hole is provided on both sides of the fixed block 4 and the movable block 41. The second lead screw 46 is connected to the threaded hole. The second lead screw 46 passes through the fixed block 4 or the movable block 41 and is rotatably connected to the side wall of the corresponding clamping plate 43. When it is necessary to clamp the material, the second lead screw 46 is rotated. The rotation of the second lead screw 46 drives the clamping plate 43 to move, thereby completing the clamping of the test material.

[0036] It should be noted that a through groove 24 is provided on the side wall of the fixed frame 2, which is connected to the first sliding groove 21. The end of the rotating rod 35 passes through the through groove 24. When the first slider 22 moves up and down, the rotating rod 35 on it moves in the through groove 24.
