The slider 38 is slidably connected to the guide rail 32, and the guide rail 32 is fixedly mounted on the top surface of the reinforcement plate 1. There are two screw rods 33, and the two screw rods 33 are rotatably set on the guide rail 32. One of the screw rods 33 is fixedly connected to the first gear 34, and the other screw rod 33 is transmission-connected to the transmission shaft 36 through a pulley set 37. The second gear 35 is fixedly mounted on the end surface of the transmission shaft 36, and the second gear 35 also meshes with the first gear 34. The transmission shaft 36 is rotatably set inside the guide rail 32, and the slider 38 is also threadedly connected to the screw rod 33. There are two splints 31, and the two splints 31 are symmetrically arranged on both sides of the center position of the reinforcement plate 1. The two splints 31 cooperate with each other to firmly clamp the reinforcement plate 1 on the aging test plate, thereby achieving the purpose of protecting the bottom wall of the plate body.

[0024] The adjusting assembly 4 includes a turntable 41, a handle 42, a linkage shaft 43, a first friction plate 44, a connecting rod 45, a second friction plate 46, a ball rod 47, a connecting seat 48, a first spring 49, a semicircular block 410, a fixing plate 411 and a second spring 412. The turntable 41 is fixedly mounted on the end surface of the linkage shaft 43, the handle 42 is slidably arranged on the turntable 41, the linkage shaft 43 is fixedly mounted on the end surface of the screw rod 33, the first friction plate 44 is fixedly mounted on the connecting rod 45, the connecting rod 45 is fixedly mounted on the ball rod 47, and the connecting rod 45 is also slidably connected to the linkage shaft 43, the second friction plate 46 is fixedly mounted on the reinforcement plate 1, the ball rod 47 is slidably arranged inside the linkage shaft 43, the connecting seat 48 is fixedly mounted on the ball rod 47, and the first and second friction plates 46 are fixedly mounted on the reinforcement plate 1. The two ends of a spring 49 are fixedly connected to the connecting seat 48 and the connecting shaft 43 respectively. The semicircular block 410 is fixedly installed on the end face of the handle 42. When in use, the handle 42 will slide away from the center of the turntable 41, thereby increasing the actual torque, allowing the user to operate the overall structure more effortlessly, and further facilitating actual use. The fixed plate 411 is fixedly installed on the semicircular block 410. The two ends of the second spring 412 are fixedly connected to the fixed plate 411 and the turntable 41 respectively. The first friction plate 44 and the second friction plate 46 are both annular in design, and the adjacent sides of the first friction plate 44 and the second friction plate 46 are provided with friction grooves for enhancing friction. In the initial state, the arc surface of the semicircular block 410 is tangent to the ball head end face of the ball head rod 47.

[0025] Working principle: when the reinforcing plate 1 is connected to the bottom wall of the aging test plate to enhance the strength of the aging test plate, the handle 42 is pushed so that the semicircular block 410 fixed on the handle 42 does not contact the ball end of the ball head rod 47. Because the turntable 41 is fixed on the linkage shaft 43, the ball head rod 47 slides inside the linkage shaft 43 and the turntable 41 through the connecting seat 48. The connecting seat 48 also uses the first spring 49 to further connect with the linkage shaft 43. When the semicircular block 410 does not contact the ball head rod 47, under the action of the first spring 49, the ball head rod 47 slides toward the turntable 41 with the connecting rod 45 fixed thereto. The first friction plate 44 fixed on the connecting rod 45 slides synchronously without contacting the second friction plate 46. At this time, the turntable 41 can be driven to rotate by the handle 42, and the synchronous linkage shaft 43 and the screw rod 33 fixedly connected to the linkage shaft 43 rotate synchronously, and the splint 31 slidably connected to the guide rail 32 and threadedly connected to the screw rod 33. As the screw rod 33 rotates, the splint 31 will slide on the guide rail 32. In this process, one of the two screw rods 33 is fixed with the first gear 34, and the other screw rod 33 is provided with a pulley set 37, which is connected to the transmission shaft 36 through the pulley set 37. The first gear 34 is also engaged with the second gear 35 fixed on the transmission shaft 36. Therefore, when the single screw rod 33 rotates in the forward direction, the other screw rod 33 will rotate in the reverse direction. The two clamping plates 31 on the two screw rods 33 are threadedly connected to the screw rods 33 through the slider 38. At this point, the two clamping plates 31 perform relative mirror sliding motions, thereby clamping the entire reinforcement plate 1 on the bottom wall of the aging test plate. Then release the handle 42. The second spring 412 with its two ends fixedly connected to the turntable 41 and the fixed plate 411, and the fixed plate 411 is fixed on the semicircular block 410. Therefore, when the second spring 412 is in Under the action, the handle 42 slides back to the center of the turntable 41, and the semicircular block 410 squeezes the ball head rod 47, so that the ball head rod 47 slides together with the first friction plate 44 toward the second friction plate 46 until the first friction plate 44 contacts the second friction plate 46. Because the second friction plate 46 is fixed on the reinforcement plate 1, and the adjacent sides of the second friction plate 46 and the first friction plate 44 are provided with friction patterns, after the two contact, the friction patterns fit each other, generating a certain friction force, thereby locking the position of the first friction plate 44, limiting the rotation of the ball head rod 47 and the screw rod 33, and further locking the position of the splint 31.
