[0035] In this embodiment, a sliding structure is formed between the mounting plate 402 and the interior of the mounting groove 401. The cross-section of the mounting groove 401 and the mounting plate 402 is inverted convex. The sliding between the inverted convex mounting plate 402 and the interior of the mounting groove 401 is utilized to improve the stability of the initial sliding installation of the serrated clamp 14.

[0036] In this embodiment, a limiting groove 404 is provided on the inner wall of the fixing groove 405, and both ends of the upper end of the positioning rod 407 are fixedly connected with limiting blocks 406 that slide in cooperation with the inside of the limiting groove 404.

At the same time, the rise of the sliding plate 10 will drive the protective cover 202 to rise synchronously, so that the protective cover 202 can shield and protect the new material during the whole process, so as to avoid the new material fragments accidentally flying too far, which will increase the difficulty of subsequent cleaning for the staff, or the damage caused by the flying fragments to the surrounding equipment or personnel, thereby improving the safety of the test. After the test is completed, the rotating rod 206 is toggled in the opposite direction to separate the card plate 204 from the inside of the card seat 201 completely.

[0041] When the teeth of the serrated clamp 14 are severely worn or need maintenance and replacement, the pull rod 403 can be pulled to drive the positioning rod 407 to rise and compress the mounting spring 409 until it is completely disengaged from the positioning hole 408, and then the serrated clamp 14 can be pushed to make the mounting plate 402 completely slide out of the mounting groove 401 for removal. During installation, the pull rod 403 is first pulled to make the positioning rod 407 completely separate from the mounting groove 401, and then the mounting plate 402 is slid into the mounting groove 401, and then the pull rod 403 is released, and the elastic force of the mounting spring 409 is used to make the mounting plate 402 drop and clamp into the positioning hole 408, so as to achieve the limited fixation of the mounting plate 402 after sliding with the mounting groove 401, so as to realize the quick disassembly and assembly of the serrated clamp 14, which is convenient for its maintenance or replacement.
