[0020] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0021] See also Figure 1-3 A novel adjustable tensile tester in this embodiment includes a base 1 and a clamping assembly. A controller 2 is installed on the right side of the top of the base 1, a lift 7 is installed on the left side of the top of the base 1, a movable seat 6 is installed on the lift 7, a fixed seat 3 is installed on the top of the base 1, and a mounting seat 5 is fixed on the opposite side of the fixed seat 3 and the movable seat 6, and a locking member for fixing the clamping assembly 4 is installed on the mounting seat 5.

[0022] The clamping assembly 4 includes a clamping seat 41, a guide rod 44 is fixed inside the clamping seat 41, and clamping plates 43 are slidably connected to the left and right sides of the outside of the guide rod 44. The two clamping plates 43 are rotatably connected to the opposite sides of the two clamping plates 43. The threaded rod 46 is threadedly connected to the inside of the clamping seat 41, and the side of the threaded rod 46 away from the clamping plate 43 is fixedly connected to a rotating block 42. The side wall of the rotating block 42 is provided with a plurality of circular grooves distributed equidistantly around.

[0023] It should be noted that the elevator 7 of the tensile tester is mainly composed of structures such as a transmission system, a guide rail system and a control system. The transmission system is the core part of the elevator, usually including components such as a motor, a reducer, and a gear box. They work together to convert electricity into mechanical energy, thereby driving the lifting and lowering of the fixture. In order to ensure the smooth lifting and lowering of the fixture, the tensile machine will be designed with a guide rail system. These guide rails can ensure the linear motion of the fixture during the lifting process, reduce deviation and vibration, and ensure the accuracy of the test results.

[0024] It can be understood that the mounting seat 5 and the clamping assembly installed on the movable seat 6 are driven to rise and fall by the elevator 7, and the clamping assembly installed on the fixed seat 3 is used to fix the other end of the material to be tested. Therefore, the distance between the two clamping assemblies can be adjusted, and the material can be subjected to a tensile test.

[0025] The locking member includes a positioning block 9 and an insertion rod 14. The positioning block 9 is fixed to the side of the clamp seat 41 close to the mounting seat 5. A positioning groove 8 is provided on the side of the mounting seat 5 close to the positioning block 9. The positioning block 9 is inserted into the inside of the positioning groove 8. The insertion rod 14 sequentially penetrates the mounting seat 5 and the positioning block 9 and extends to the outside. The external thread of the insertion rod 14 is connected to the annular plate 13.

[0026] It can be understood that by providing a locking piece to fix the clamping assembly, it is convenient to disassemble and replace different types of clamps, so that it is suitable for testing different types of materials and has good applicability.

[0027] In this embodiment, the arc rod 11 is fixed to one side of the annular plate 13 away from the mounting seat 5 , and a stopper is fixed to one end of the insertion rod 14 away from the annular plate 13 .

[0028] The setting of the stopper can limit the insertion rod 14 , so that the insertion rod 14 passes through the mounting seat 5 and the positioning groove 8 and extends to the outside, and the stopper can be pressed against the side wall of the mounting seat 5 .

[0029] See also Figure 2 , Figure 3 A U-shaped block 10 is fixed to one side of the mounting seat 5 , and the U-shaped block 10 is internally rotatably connected to a limiting plate 12 , the limiting plate 12 is a “U”-shaped plate, and the arc rod 11 is located inside the limiting plate 12 .

[0030] The limiting plate 12 is provided to limit the arc rod 11, so that the annular plate 13 is not easy to rotate, thereby ensuring stability.

[0031] See also Figure 1 , Figure 2 Two guide rods 44 are fixed inside the clamp seat 41, and the two guide rods 44 are symmetrically distributed front to back. The two clamp plates 43 are slidably connected to the outside of the two guide rods 44. The outside of the guide rods 44 is provided with a telescopic spring 45, and the telescopic spring 45 is installed between the clamp plate 43 and the inner wall of the clamp seat 41.

[0032] It should be noted that the guide rod 44 is provided to guide the clamping plate 43 , so that when the rotating block 42 rotates, the clamping plate 43 is pushed to translate, so that the two clamping plates 43 clamp and fix the material to be tested.

[0033] The working principle of the above embodiment is as follows: when in use, the material to be tested is placed between the two clamping plates 43. Under the limiting action of the sliding connection between the clamping plates 43 and the guide rods 44, the rotating block 42 is rotated to move the clamping plates 43 to one side of the material to be tested until it is clamped and fixed. The two clamping plates 43 are used to facilitate clamping of flat materials. If it is necessary to clamp special-shaped or different types of materials, the limiting plate 12 is rotated away from the arc rod 11, and the arc rod 11 is then rotated to drive the annular plate 13 to rotate until the annular plate 13 is removed from the insertion rod 14. After that, the insertion rod 14 is pulled out, and the positioning block 9 can be removed from the positioning groove 8, so that the clamp seat 41 can be disassembled conveniently, and different types of clamps can be replaced conveniently to improve applicability.

Moreover, the terms "include", "comprise" or any other variants thereof are intended to cover non-exclusive inclusion, so that a process, method, article or device including a series of elements includes not only those elements, but also other elements not explicitly listed, or also includes elements inherent to such process, method, article or device.
