[0024] The lower clamping structure 7 and the upper clamping structure 6 include a mounting block 701, a fixed clamping plate 703, a movable clamping plate 702 and a fastener 704. A fixed clamping plate 703 is fixedly installed on the upper surface of the mounting block 701 of the lower clamping structure 7 and the lower surface of the mounting block 701 of the upper clamping structure 6. A movable clamping plate 702 is movably installed on the upper surface of the mounting block 701 of the lower clamping structure 7 and the lower surface of the mounting block 701 of the upper clamping structure 6 and in front of the fixed clamping plate 703. Fasteners 704 are embedded near both sides on the front surface of the movable clamping plate 702. The rear ends of the fasteners 704 penetrate through the fixed clamping plate 703. Chutes 705 are formed on the upper surface of the mounting block 701 of the lower clamping structure 7 and the lower surface of the mounting block 701 of the upper clamping structure 6 and in front of the fixed clamping plate 703. The chutes 705 can assist the smooth movement of the movable clamping plate 702 and prevent the movable clamping plate 702 from separating from the mounting block 701. A support column 706 is fixedly installed on the lower surface of the mounting block 701 of the lower clamping structure 7. An extension block 707 is fixedly installed on the rear surface of the support column 706. Guide rods 708 are fixedly installed on both side surfaces at the rear end of the extension block 707. A stop block 709 is fixedly installed on one end surface of the guide rod 708. A connecting plate 601 is fixedly installed on the rear surface of the mounting block 701 of the upper clamping structure 6. Rack bars 602 are fixedly installed on both end surfaces of the connecting plate 601. The vertically moving rack bars 602 can drive the gear 902 to rotate. Flipping blocks 801 are fixedly installed near both sides on the front end surface of the flip plate 8. A rod groove 802 is formed inside the flipping block 801. One end of the guide rod 708 extends into the rod groove 802. A torsion spring 710 is sleeved on the surface of the guide rod 708 located inside the rod groove 802. One end of the torsion spring 710 is fixed to the inner end surface of one end of the rod groove 802, and the other end of the torsion spring 710 is fixed to the stop block 709. The upper clamping structure 6 is fixed to the lifting plate 5 through the mounting block 701, and the lower clamping structure 7 is fixed to the base 1 through the support column 706.

One end of the movable rod 901 is movably connected to the mounting block 701 of the lower clamping structure 7, and the other end of the movable rod 901 is movably connected to the support frame 2. A gear 902 is fixedly sleeved on the surface of the movable rod 901. The distance between the side baffles 9 is smaller than the width of the flip plate 8. The rack bars 602 are engaged with the gear 902. The side baffles 9 can shield both sides of the item to be detected to prevent the item from flying to both sides after breaking during the detection process.

[0025] It should be noted that the present utility model is a tightness adjustment structure of a tensile testing device. When in use, after the upper and lower ends of the item to be tested are respectively fixed by the upper clamping structure 6 and the lower clamping structure 7, as the upper clamping structure 6 continuously rises, under the cooperation of the rack 602 of the upper clamping structure 6 and the gear 902, the side baffle 9 will be driven to rotate forward. The flipped-up side baffle 9 can prevent the broken item from ejecting onto the tester. As the side baffle 9 flips up, the flap 8 will be flipped to the vertical state under the action of the torsion spring 710. The flap 8 can prevent the item from flying backward. After the side baffle 9 is flipped to the vertical state, due to its certain width, even if the upper clamping structure 6 continues to rise and the side baffle 9 continues to rotate forward, the relatively wide side baffle 9 can still play a protective role.

[0026] The above shows and describes the basic principles, main features and advantages of the present utility model. Those skilled in the art should understand that the present utility model is not limited by the above embodiments. The above embodiments and the descriptions in the specification only illustrate the principles of the present utility model. Without departing from the spirit and scope of the present utility model, the present utility model will have various changes and improvements, and these changes and improvements all fall within the scope of the present utility model claimed.
