Cross connecting rod and fixed plate is fixed on the top of lever main body.
Further, connecting rod is two symmetrical both sides for being fixed on support pouring weight, and the support pouring weight is in institute
State the surface of lever main body central point, the free ends of two connecting rods is connected lever main body by a piece of fixed plate respectively
Two ends.
Further, lever main body two ends are also each spirally connected balancing weight.
Further, support pouring weight is provided with the spirit bubble for being used for detecting lever main body horizontality.
The beneficial effects of the utility model are：
1. lever main body and Micro-force sensor are more accurate relative to the front and back position of iron stand, it is not necessary to adjust.
2. regulation lever balance is convenient in a free state：By the balancing weight for adjusting lever left and right ends, it is only necessary to one
Step can just be completed, and easy to adjust and accurate, equilbrium position is not easily moved about.
3. whether spirit bubble detection lever balances：The existing lever equilibrium condition tester lever that can only detect by an unaided eye is
No balance, error is larger.Increase spirit bubble, can judge whether lever is in poised state with simple and clear, and error is smaller,
Preparation is high, and observation is convenient.
4. the scale value of silk-screen is continuous on lever, accurately.It can realize and test down at an arbitrary position.
5. Micro-force sensor：Measure accuracy rate higher, it is easy to use.
6. directly the fixed seat on lever main body is fixed on iron stand with Quincunx screw before experiment, lever main body is fixed
Settle at one go, it is simple to operate.
