[0024] The first fixed seat 4 is connected to a copper rod 5. The top of the base 1 is equipped with a slide rail mechanism, which is connected to a second fixed seat 6. The second fixed seat 6 is connected to a carbon rod 7. The slide rail mechanism includes two slide rails 8 fixedly connected to the top of the base 1. The two slide rails 8 are symmetrically arranged and are firmly fixed to the top of the base 1. The bottom of the first fixed seat 4 and the second fixed seat 6 are provided with two slide grooves 9 that are adapted to the slide rails 8. The inner sidewalls of the two slide grooves 9 are slidably connected to the outer sidewalls of the slide rails 8. This design allows the first fixed seat 4 and the second fixed seat 6 to slide flexibly and stably along the slide rails 8, ensuring the stability of the device during operation.

[0025] The first fixing seat 4 has a first placement groove 10 on its top, and the copper rod 5 is located in the first placement groove 10. In order to further ensure the stability of the copper rod 5 during the test, the first fixing seat 4 has a first pressure block 11 on its top, and the bottom of the first pressure block 11 has a first arc-shaped groove that matches the copper rod 5, which can tightly fix the copper rod 5 in the first placement groove 10.

[0026] The second fixing seat 6 has a second placement groove 12 at its top, and the carbon rod 7 is located in the second placement groove 12. In order to ensure the stability of the carbon rod 7, the second fixing seat 6 has a second pressing block 13 at its top, and the bottom of the second pressing block 13 has a second arc-shaped groove that matches the carbon rod 7.

[0027] A vertically arranged baffle 14 is fixedly connected to the top of the base 1. The baffle 14 has two symmetrically arranged movable openings 15. An optical axis 16 is slidably connected to the inner side wall of the movable opening 15. The end of the optical axis 16 abuts against the outer side wall of the second fixed seat 6.

[0028] A buffer spring 17 is fitted on the outer wall of the optical axis 16. The two ends of the buffer spring 17 are fixedly connected to the outer wall of the baffle 14 and the outer wall of the optical axis 16, respectively. This design plays an important role in buffering and protection during the operation of the device. In particular, when the copper rod 5 and the carbon rod 7 come into contact and collide, it can effectively reduce the impact force and avoid damage to the device and the test materials.

[0029] The specific working principle of this utility model is as follows:

[0030] In the initial state, when a copper-carbon rod arc ignition test is required, the servo motor 2 is started first. After the servo motor 2 starts running, its output end drives the threaded rod 3 to rotate. Since the threaded rod 3 is connected to the first fixed seat 4 by a threaded sleeve, the first fixed seat 4 will move along the axial direction of the threaded rod 3, thereby driving the copper rod 5 placed on the first fixed seat 4 to move closer to the carbon rod 7. At the same time, the second fixed seat 6 can be flexibly adjusted in position through the slide rail 8 mechanism to ensure that the carbon rod 7 is in a suitable test position. When the copper rod 5 gradually approaches the carbon rod 7 and reaches a suitable distance, an arc ignition phenomenon will occur between the two. During this process, if the copper rod 5 and the carbon rod 7 come into contact and collide, the optical axis 16 will slide in the movable opening 15, and the buffer spring 17 will be compressed to play a buffering role and avoid damage to the device due to excessive impact force.

[0031] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
