[0026] The present invention provides a separation force detection fixture. A clamping gap 210 is formed between the first clamping arm 21 and the second clamping arm. The first clamping arm 21 and the second clamping arm 22 are rotatably connected, and the first clamping portion 211 of the first clamping arm 21 is driven by the first adjustment member 231 to move away from the second clamping portion 221 of the second clamping arm 22 to increase the clamping gap 210, so that the object to be tested can extend into the clamping gap 210. After clamping, the second adjustment member 232 can be used to maintain the clamping state of the first clamping arm 21 and the second clamping arm 22. After clamping, the separation force test can be carried out.

One end of the second clamping arm 22 away from the mounting base 24 extends obliquely towards the first clamping arm 21, and at the end of the second clamping arm 22, the second clamping portion 221 is formed.

[0030] In this embodiment, the first clamping portion 211 is formed at the lower end of the first clamping arm 21, and the second clamping portion 221 is formed at the lower end of the second clamping arm 22.

[0031] In this embodiment, the first clamping portion 211 is a first clamping plate, the second clamping portion 221 is a second clamping plate, the first clamping plate and the second clamping plate are arranged oppositely, and the first clamping plate extends along the vertically downward direction, the second clamping plate extends along the vertically downward direction, and a clamping gap 210 is formed between the first clamping plate and the second clamping plate.

[0032] In this embodiment, a fulcrum 220 is formed at the connection between the first clamping arm 21 and the second clamping arm 22, and the first adjusting member 231 and the second adjusting member 232 are respectively at both ends of the fulcrum 220.

[0033] In this embodiment, the middle part of the second clamping arm 22 is connected to the middle part of the first clamping arm 21.

[0034] In this embodiment, using the lever principle, a fulcrum 220 of the lever principle is formed at the connection between the first clamping arm 21 and the second clamping arm 22. That is, the second clamping arm 22 can rotate on the first clamping arm 21 around the fulcrum 220.

[0035] In this embodiment, a connecting arm extends outward at the first clamping arm 21, and a through groove 212 is formed between the connecting arms. The second clamping arm 22 passes through the through groove 212. A support shaft 213 is provided at the through groove 212. The second clamping arm 22 is connected to the first clamping arm 21 through the support shaft 213, so that the second clamping arm 22 is rotatably connected to the first clamping arm 21.

[0036] In this embodiment, the first adjusting member 231 is an elastic member. One end of the elastic member is connected to the first clamping arm 21, and the other end is connected to the second clamping arm 22. And the elastic member is at one end of the fulcrum 220 close to the clamping gap 210.

[0037] In some embodiments, a first groove 219 is provided on the first clamping arm 21, and a second groove is provided on the second clamping arm 22. The first groove and the second groove are arranged opposite to each other. One end of the elastic member extends into the first groove 219 and is fixedly connected to the bottom wall of the first groove; the other end of the elastic member extends into the second groove and is fixedly connected to the bottom wall of the second groove.

[0038] In this embodiment, the elastic member is a spring.

[0039] The elastic member is between the first clamping arm 21 and the second clamping arm 22 to drive the first clamping portion 211 of the first clamping arm 21 and the second clamping portion 221 of the second clamping arm 22 to move in a direction away from each other, so as to increase the clamping gap 210, so that the object to be measured can extend into the clamping gap 210.

[0041] When the adjusting screw extends toward the first clamping arm 21 through the first connection hole and a first distance is formed between the adjusting screw and the first clamping arm 21, since the elastic member drives the second clamping portion 221 to move in a direction away from the first clamping portion 211, the second clamping arm 22 rotates relative to the first clamping arm 21, so that the clamping gap 210 increases. At this time, the object to be measured can be extended into the clamping gap 210.

[0042] When the adjusting screw extends through the first connection hole towards the first clamping arm 21 and abuts against the first clamping arm 21, the rotation of the second clamping arm 22 at the first clamping arm 21 is restricted, so as to keep the first clamping part 211 of the first clamping arm 21 and the second clamping part 221 of the second clamping arm 22 in a clamped state.

[0048] The connecting member 1 extends towards the mounting base 24 to form a screw rod, which is connected to the second connection hole on the mounting base 24, so that the mounting base 24 and the connecting member 1 are detachably connected together. In this embodiment, the screw rod extends from the bottom of the connecting member 1, the second connection hole is opened at the top of the mounting base 24, and internal threads are formed on the inner wall of the second connection hole.

[0049] A mounting groove 241 is formed at the bottom of the mounting base 24. The first clamping arm 21 is connected to the mounting groove 241 through a movable shaft, so that the first clamping arm 21 is rotatably connected to the mounting base 24.

[0050] A connecting arm 214 is bent at one end of the first clamping arm 21 close to the connecting assembly 1. The first clamping arm 21 extends into the mounting groove 241 through the connecting arm 214 and is rotatably connected to the mounting base 24.

In this embodiment, the speed when the tensile testing machine pulls upwards is set, and the magnitude of the separation force is obtained when the speed of the tensile testing machine is constant.

[0052] In this embodiment, the clamping gap 210 between the first clamping portion 211 of the first clamping arm 21 and the second clamping portion 221 of the second clamping arm 22 can be used to clamp the sealing film of skin care products or the sealing film of medicine bottles.
