Construction features
1. Measuring component and buckling component of products is located between enter line end and entrance line end ;
2. Movement characteristic of products can not be changed with outside mechanical tool ;
3.The operating organization has the free function to take off and buckle;
4. Operate part can not be taken down from the shell outer of products ,the shell can not influence the operating organization to work, the accessory group which replace the feelers pressure ,should guarantee the feelers pressure does not change while running .
5. Overall and mounting dimensioned chart.
