[0020] The pressing mechanism 3 includes a fixed pressing plate 31, a movable pressing plate 32, a guide rail 33, a slider 34, and a cylinder 35. The fixed pressing plate 31 is rotatably connected to the left end of the upper surface of the steel plate 1 via a rotating shaft. The guide rail 33 is located at the right end of the upper surface of the steel plate 1. The slider 34 is laterally slidably connected inside the guide rail 33. A cylinder 35 is provided on the upper surface of the slider 34. The outer arc surface of the cylinder 35 is rotatably connected to the elastically limited movable pressing plate 32. The slider 34 slides within the guide rail 33. The left and right positions of the movable pressing plate 32 are adjusted according to the different lengths of the highly adaptable composite film bags. The angle of the movable pressing plate 32 is adjusted by the relative rotation of the movable pressing plate 32 and the cylinder 35. Pressing the fixed pressing plate 31 and the movable pressing plate 32 causes deformation, thus adjusting the appropriate... The left and right ends of the highly compatible composite film bag are pressed against the workbench surface to ensure that the position between the highly compatible composite film bag and the steel ruler is fixed during the testing process, thereby improving the accuracy of the test results. The angle of the fixed pressure plate 31 is adjusted by the relative rotation of the fixed pressure plate 31 and the steel plate 1, reducing the space occupied by the steel ruler in the storage state. The pressing mechanism 3 also includes a rectangular plate 36 and a rectangular groove 37. The rectangular plate 36 is located at the lower end of the outer arc surface of the cylinder 35, and the rectangular groove 37 is located at the right end of the upper surface of the movable pressure plate 32. The rectangular plate 36 and the rectangular groove 37 are inserted into each other. By inserting the rectangular plate 36 and the rectangular groove 37, the relative rotation between the movable pressure plate 32 and the cylinder 35 is restricted, and the angle of the movable pressure plate 32 is determined. The pressing mechanism 3 also includes The mechanism includes rubber pads 38, which are respectively disposed on the lower surfaces of the fixed pressure plate 31 and the movable pressure plate 32, increasing the friction between the lower surfaces of the fixed pressure plate 31 and the movable pressure plate 32, and improving the holding firmness. The holding mechanism 3 also includes positioning baffles 39, which are respectively disposed on the left end of the upper surface of the steel plate 1 and the right end of the upper surface of the slider 34. When the fixed pressure plate 31 contacts the positioning baffle 39 on the left, the fixed pressure plate 31 is perpendicular to the steel plate 1. When the movable pressure plate 32 contacts the positioning baffle 39 on the right, the movable pressure plate 32 is perpendicular to the steel plate 1. The upper end of the cylinder 35 is provided with a limiting plate 4. The outer arc surface of the cylinder 35 is vertically slidably connected to a ring 6. A spring is provided between the upper surface of the ring 6 and the lower surface of the limiting plate 4. Spring 5 is movably sleeved on the outer arc surface of cylinder 35. Under the elastic force of spring 5, ring 6 applies a downward force to movable pressure plate 32, elastically limiting movable pressure plate 32. Limiting plate 4 is movably sleeved on the outer arc surface of screw at the upper end of cylinder 35. A nut is threaded to the upper end of screw, and the nut is used to fix limiting plate 4 to the outer arc surface of screw at the upper end of cylinder 35.

[0021] The working principle of the highly adaptable composite film bag laboratory steel ruler provided by this utility model is as follows: When testing the highly adaptable composite film bag, both the composite film bag and the steel ruler are placed on the workbench. The steel ruler is moved so that the steel plate 1 is in contact with the edge of the highly adaptable composite film bag. The fixed pressure plate 31 is rotated until it contacts the positioning baffle 39 on the left. At this time, the fixed pressure plate 31 and the steel plate 1 are perpendicular to each other. Under the action of the friction between the fixed pressure plate 31 and the steel plate 1, the fixed pressure plate 31 is not... It will easily rotate, maintaining a state perpendicular to the fixed pressure plate 31 and the steel plate 1. By pressing the fixed pressure plate 31 to deform it, the left end of the composite film bag is pressed onto the worktable, fixing the left end of the composite film bag to the starting position of the steel ruler. Then, the movable pressure plate 32 is lifted upward against the spring 5, causing the rectangular plate 36 to leave the rectangular groove 37. At this time, the movable pressure plate 32 can be pushed to rotate around the cylinder 35. When the movable pressure plate 32 contacts the positioning baffle 39 on the right, the movable pressure plate 32 and the steel plate 1... Perpendicular to each other, after releasing the movable pressure plate 32, under the elastic force of the spring 5, the ring 6 applies a downward force to the movable pressure plate 32, causing it to move downward. The rectangular plate 36 inserts into the rectangular groove 37, restricting the relative rotation between the movable pressure plate 32 and the cylinder 35, maintaining the movable pressure plate 32 and the steel plate 1 perpendicular to each other. Then, according to the position of the right end of the composite film bag, the slider 34 is pushed to slide laterally within the guide rail 33 to adjust the left and right position of the movable pressure plate 32. When the movable pressure plate 32 moves to... After pressing the right end of the composite film bag, press the movable pressure plate 32 to deform it, pressing the right end of the movable pressure plate 32 onto the workbench, fixing the position between the right end of the composite film bag and the steel ruler. Finally, use the magnifying glass 7 to observe the right end of the composite film bag at the corresponding scale strip 2 position on the steel plate 1, and test the length of the composite film bag. After the test is completed, repeat the above operation in reverse, rotating both the fixed pressure plate 31 and the movable pressure plate 32 to a state parallel to the steel plate 1, reducing the space occupied by the steel ruler when storing it.
