The inside of pendulum arc plate 4 is installed with fixed peg 5, for connecting and fixing relevant components, play the effect of control variable. The side of support plate 2 and fixed peg 5 is provided with sample clamping assembly 6, and sample clamping assembly 6 is used for clamping film sample, to ensure that sample keeps stable during testing. The lower of two sample clamping assemblies 6 is provided with cutting assembly 7, and cutting assembly 7 is used for standardizing the incision operation of film sample, to ensure that testing meets the standardization requirement. The inside of workbench 1 is provided with storage assembly 8, and storage assembly 8 is used for storing different levels of weight 501 and other test accessories, by reasonable layout, avoid the loss or messy problem of weight 501, improve the practicability and management convenience of equipment.

[0034] With reference to Figure 1 - Figure 3The sample clamping assembly 6 comprises a U-shaped block 601 which is an integral frame structure, and the inside of the U-shaped block 601 is designed to fix and guide the movement of the clamping assembly, while improving the stability and durability of the structure. The inner side of the U-shaped block 601 is provided with two clamping plates 602, which are respectively located on both sides of the inside of the U-shaped block 601, and the opposite side of each clamping plate 602 is fixedly connected with a rubber protrusion 603. The rubber protrusions 603 have softness and certain friction, which can effectively avoid scratching or tearing the film when clamping the sample, and at the same time, by increasing the contact area, it can ensure that the sample does not slip during the test, and further improve the accuracy of the test results. One of the clamping plates 602 is directly installed on the inside of one side of the U-shaped block 601 by means of bolt fixation, so as to keep it fixed, and the other clamping plate 602 is connected with the inside of the other side of the U-shaped block 601 through a plurality of springs 604. The springs 604 can provide a constant elastic force for the clamping plate 602, so that when the hand lever 605 is loosened, the clamping plate 602 can automatically approach the fixed clamping plate 602 to realize the function of rapid clamping, which greatly simplifies the operation process.

[0035] In order to further improve the flexibility of operation, the outer side of the clamping plate 602 is fixedly connected with a hand lever 605 which penetrates through the side wall of the U-shaped block 601 and can be slidingly connected inside the side wall. The design of the hand lever 605 facilitates the operator to adjust the position of the clamping plate 602 by simply pulling the hand lever 605. When the hand lever 605 is pulled, the clamping plate 602 will compress the spring 604 on it together, thereby increasing the distance between the clamping plates 602, which is convenient for placing the sample; when the hand lever 605 is loosened, the elastic force of the spring 604 will automatically reset the clamping plate 602 to firmly clamp the sample between the two clamping plates 602.

The two sides of the storage box 801 are fixedly connected with limiting strips 803, which ensure the stability of the storage box 801 during sliding and prevent shaking or deviation, thereby improving the convenience of storage and use. In order to facilitate the use of the operator, one side of the storage box 801 is fixedly connected with a handle 802, which is designed in accordance with ergonomics to facilitate the operator to pull out or push in the storage box 801 smoothly. The bottom of the storage box 801 is slidingly connected in an inner groove 804 inside the workbench 1, which is an embedded structure to ensure that the storage box 801 always moves along the fixed track during the pulling and pushing process, avoiding misoperation or position deviation, and further improving the space utilization and storage efficiency of the whole device.

The top of the fixed plate two 702 is installed with a cutter 703 made of high-strength material, which has sharp cutting performance and can accurately cut the film sample. The installation position of the cutter 703 is accurately adjusted to ensure that its cutting path meets the test standard requirements, providing consistency and reliability for the subsequent tear strength test. The fixed plate one 701 is stably connected outside the support plate 2 to provide a support and fixed basis for the whole cutting assembly 7, ensuring the stability and precision of the cutting operation.

[0038] Two limiting rods 705 and a control rod 704 are arranged between the fixed plate two 702 and the fixed plate one 701, and the limiting rods 705 and the control rod 704 realize the flexible movement of the cutting assembly 7 through their sliding connection structure. The main function of the limiting rods 705 is to limit the movement range of the fixed plate two 702, ensuring that the cutter 703 remains in the predetermined track during the cutting process, preventing the cutting path from deviating or excessive sliding, thereby improving the accuracy and safety of the cutting. The control rod 704 is designed for the operator to control the cutting action, which is slidingly connected outside the fixed plate one 701, so that the operator can flexibly adjust the movement of the fixed plate two 702 through the control rod 704, thereby controlling the cutter 703 to pre-cut the sample, which is convenient for the later tear test. In addition, the ends of the two limiting rods 705 and the control rod 704 are fixedly connected inside the fixed plate two 702, which can effectively improve the stability and movement coordination of the fixed plate two 702.
