[0002] MEMS inertial sensors are mainly used in consumer electronics products such as mobile phones, GPS navigation, game consoles, digital cameras, music players, wireless mice, PDs, hard disk protectors, smart toys, pedometers, and anti-theft systems. Due to their basic measurement functions such as acceleration measurement, tilt measurement, vibration measurement, and even rotation measurement, there will be more and more consumer electronics applications to be explored.

[0003] After the MEMS inertial sensor is manufactured, the component needs to be tested for strength. However, under the existing technology, the component cannot be quickly positioned during testing, and the component cannot be firmly fixed on the workbench for strength testing, which results in a large amount of time and manpower consumption and a decrease in production.

The user starts motor 1 to move the rotating shaft and the transmission belt at the same time. The movement of the transmission belt drives the bidirectional threaded rod to rotate, so that the moving block 1 and the moving block 2 on the bidirectional threaded rod move in relative directions and drive the clamping block 1 and the clamping block 2 to quickly position and clamp the component, thereby solving the problem that the component cannot be quickly positioned when being detected and the component cannot be firmly fixed on the workbench for strength detection, thereby consuming a lot of time and manpower and reducing production.

[0005] In order to solve the above technical problems, the utility model is realized by the following technical solutions:

[0014] 1. The utility model sets a clamping block 1. Specifically, the user starts the motor 1 to rotate the rotating shaft and drive the transmission belt to move at the same time. Under the action of the transmission belt, the bidirectional threaded rod moves.

[0027] A specific application of this embodiment is: the user places the component to be inspected on the gasket 11, then starts the motor 1 24 to rotate the rotating shaft 241, and the synchronous movement of the transmission belt 25 causes the bidirectional threaded rod 22 fixed inside the fixed column 26 to rotate.

Since the bevel gear 1 311 is meshed and connected with the bevel gear 2 312, the bevel gear 2 312 drives the threaded rod 33 to rotate at the same time. When the threaded rod 33 moves, the rotating block 34 descends, and the descent of the rotating block 34 drives the connecting block 42 and the cross bar 55 to descend at the same time. Since the slideway 1 4 fixed on the left side of the connecting block 42 is slidably connected with the slider 2 41, it is smoother when descending and will not deviate. Then the detection probe 541 contacts the component to perform strength detection on the component.
