[0019] In order to make the purpose and advantages of this utility more clear, the utility is described in detail below with reference to the embodiments. It should be understood that the following text is only used to describe one or several specific implementation methods of this utility and does not strictly limit the scope of protection specifically requested by this utility.

[0020] like Figure 1-Figure 3As shown, a flexible package tensile test fixture includes a mounting plate 1, and two clamps 2 are movably connected to the bottom surface of the mounting plate 1. An elastic member is arranged between the clamp 2 and the mounting plate 1, and the side walls on the opposite sides of the clamp 2 are fixedly connected with a clamping block 5, and the clamping blocks 5 on both sides are staggered. The clamping blocks 5 are all trapezoidal structures, which are used to increase the contact surface with the flexible package and increase the friction force. The right side clamp 2 and the clamping block 5 are both hollow structures, and the inner cavity of the clamping block 5 is provided with a trapezoidal block 6. The trapezoidal block 6 is respectively provided with an insertion rod 7 on the upper and lower sides. The insertion rod 7 is L-shaped, which is convenient for assembling a rebound part on the insertion rod 7. The insertion rod 7 passes through the clamping block 5 and is movably connected to it. The side wall of the insertion rod 7 is provided with a rebound component, and the side wall of the left clamping block 5 is provided with a slot 14 corresponding to the insertion rod 7, and the inner cavity of the right splint 2 is provided with a driving component.

[0021] like Figure 1 and Figure 2 As shown, the tensioner includes a movable block 3 fixedly connected to the top surface of the clamping plate 2. Two slide slots are defined on the bottom surface of the mounting plate 1. The movable block 3 is slidably connected to the slide slots. A screw 4 is threadedly connected between the two movable blocks 3. The sidewall threads of the screw 4 are symmetrically arranged in opposite directions. The tensioner utilizes a conventional vise or other clamping structure, which is state of the art and therefore will not be described in detail in this solution.

[0022] like Figure 2 As shown, the drive assembly includes a fixed plate 9 arranged in the inner cavity of the right splint 2, and a plurality of connecting plates 8 are fixedly connected to the left wall of the fixed plate 9. The connecting plates 8 all pass through the splint 2 and are fixedly connected to the trapezoidal block 6. The side wall of the right splint 2 is threadedly connected with a bolt 10, and the bolt 10 is rotatably connected to the fixed plate 9.

[0023] Among them, when the bolt 10 is rotated, the connecting plate 8 and the trapezoidal block 6 can be pushed to move synchronously through the fixing plate 9, so that the insertion rod 7 can be inserted into the slot 14 synchronously, thereby achieving a stable fixation effect and effectively improving its stability in use.

[0024] like Figure 3 As shown, the resilient member includes a positioning rod 11 fixedly connected to the side wall of the insertion rod 7, a positioning hole 12 is opened on the inner wall of the clamping block 5, and a spring 13 is fixedly connected between the positioning rod 11 and the positioning hole 12.

[0025] When the soft package needs to be loosened, the reverse bolt 10 drives the trapezoidal block 6 to move to the right, and the force of the spring 13 is used to drive the insertion rod 7 out of the slot 14, so as to achieve the purpose of convenient reset.

[0026] The working principle of the utility model is as follows: first, the mounting plate 1 is installed on the tensile testing equipment, and then the soft package is placed between the clamping blocks 5 on both sides, and then the screw 4 is rotated to drive the movable block 3 to move relative to each other, and the movable block 3 drives the clamping block 5 to squeeze the soft package through the splint 2, which can increase the contact surface between the soft package and the splint 2, and then the bolt 10 is rotated to push the connecting plate 8 to move through the fixed plate 9, and the connecting plate 8 drives the trapezoidal block 6 to push the insertion rod 7 to move outward, and at the same time the spring 13 is compressed, so that the insertion rod 7 is inserted into the slot 14, and the soft package is fixed for a second time, thereby further improving its stability.

[0027] The above description is only a preferred embodiment of the present invention. It should be noted that those skilled in the art can make various improvements and modifications without departing from the principles of the present invention, and such improvements and modifications should also be considered within the scope of protection of the present invention. Structures, devices, and operating methods not specifically described or explained in this application shall be implemented in accordance with conventional means in the art unless otherwise specified or limited.
