The utility model clamps the clamping assembly by tweezers, so that the force sensor obtains the clamping force information, which is particularly suitable for high-precision medical tweezers, and has the advantages of simple structure, fast testing and high accuracy.

[0004] However, the device still has the following defects:

[0005] When the device is in use, the position of the second clamp is not fixed. When the test is performed, the second slider slides, which consumes force and causes deviations in the test results. At the same time, the tweezers are not fixed and need to be taken and placed all the time during the test, which is troublesome. Therefore, we need to propose a medical tweezers clamping force test tool. Utility Model Content
