[0028] Specifically, such as Figure 2 , Figure 4 As shown, the displacement assembly 202 includes a movable plate 202a disposed at the bottom of the puncture needle body 1 of the strength testing machine. A storage rack 202b is slidably connected to the top of the inner side of the movable plate 202a. The top of the inner side of the storage rack 202b is engaged with the bottom fixing plate 201d.

[0029] Specifically, such as Figure 2 , Figure 4 As shown, storage channels 202c are fixedly connected to the front and rear sides of the storage rack 202b. The bottom of the storage channel 202c is rotatably connected to a moving wheel 202d.

[0031] In this embodiment: by setting up a movable plate 202a, a storage rack 202b, a storage channel 202c, a movable wheel 202d, and a fixing rod 202e, when using this blown film puncture resistance testing structure, the user can use a circular clamp 201a to receive and fix the test film, so that the test film is in a fixed state. At the same time, the support plate 201b, the positioning rod 201c, and the bottom fixing plate 201d provided on the surface of the circular clamp 201a can facilitate the user to place it inside the storage rack 202b, so that the user can use the puncture needle body 1 of the strength testing machine for puncture testing later.

[0032] Specifically, such as Figure 5 As shown, the bottom of the puncture needle body 1 of the strength testing machine is provided with an auxiliary component 3. The auxiliary component 3 includes a reinforcing rod 301 threadedly connected to both sides of the inner side of the storage frame 202b.

[0033] Specifically, such as Figure 5As shown, a sliding rod 303 is fixedly connected to the bottom of the reinforcing plate 302, and the side of the sliding rod 303 away from the reinforcing plate 302 is hemispherical.

[0034] In this embodiment: by setting up a reinforcing rod 301, a reinforcing plate 302 and a sliding rod 303, the reinforcing rod 301, the reinforcing plate 302 and the sliding rod 303 cooperate with each other. By rotating the reinforcing rod 301, under the action of the thread, the reinforcing rod 301 drives the reinforcing plate 302 to fit against the surface of the bottom fixing plate 201d, thereby completing the clamping and fixing. At the same time, the reinforcing plate 302 will not shift under the positioning of the sliding rod 303.

[0035] Specifically, such as Figure 2 As shown, the bottom of the positioning rod 201c is slidably connected to the inner side of the storage channel 202c, and a through hole is provided on the inner side of the positioning rod 201c.

[0036] Specifically, such as Figure 4 As shown, the front side of the movable plate 202a is threadedly connected to the surface of the fixed rod 202e, and a groove is provided on the inner side of the movable plate 202a.

Simultaneously, the support plate 201b, positioning rod 201c, and bottom fixing plate 201d on the surface of the circular clamp 201a allow the user to easily place it inside the storage rack 202b, facilitating subsequent puncture testing using the puncture needle body 1 of the strength testing machine. When storing the circular clamp 201a in batches, the user can insert the bottom fixing plate 201d and positioning rod 201c into the storage rack 202b and storage channel 202c. At this time, the circular clamp 201a and storage rack 202b... The structure is located at the top of the moving plate 202a. During testing, the user only needs to move the storage rack 202b, storage channel 202c, positioning rod 201c and other structures to the bottom of the puncture needle body 1 of the strength testing machine using the moving wheels 202d. This allows the user to rotate the fixing rod 202e. Under the action of the thread, the fixing rod 202e moves inside the moving plate 202a towards the inside of the storage channel 202c and the positioning rod 201c, so that the circular clamp 201a of the storage channel 202c and the positioning rod 201c is fixed at the bottom of the puncture needle body 1 of the strength testing machine, which is convenient for use in testing. After the test is completed, the fixing rod 202e is released, and the left-side undetermined circular clamp 201a is moved to the fixed position to continue the test, thus completing the batch test.
