Board connects, and is cased with screw rod in the threaded hole of connecting column, threaded hole is used cooperatively with screw rod, and the upper end of screw rod, which is connected with, holds
Plate.
The features of the present invention also characterized in that:
Guide sleeve includes tubing string, and raised edges are provided on tubing string bottom margin, and connecting column, protrusion side are cased in tubing string
Edge is arranged above bottom support bracket.
Bottom support bracket includes bottom plate, and bottom plate both sides are equipped with side wall perpendicular to the base plate, the side wall on bottom support bracket both sides with
It is bolted to connection between raised edges.
It is fixedly connected between the closed end of connecting column and bottom deck by countersunk bolt.
It is fixedly connected between the upper end of screw rod and top deck by countersunk bolt.
The beneficial effects of the present invention are:
This device solves the problems, such as that force snesor because external force reason tilts, can make power in actual application
The upper and lower surface of sensor is smooth, and power can be transmitted uniformly.Power is by the force snesor that is transmitted to of the parts uniformity on device, not shadow
Ring the normal use of force snesor.It simultaneously can be by adjusting screw rod being screwed into depth and meet different tests pair in connecting column
The requirement of present apparatus height, application performance improve.
