As a kind of further improvement, it is provided with column on the trolley, the clump weight is through on column.Column is used
In fixed weight block, the quantity by increasing and decreasing clump weight is also adjustable drag size.
As a kind of further improvement, the column is two.Better fixed weight block, preventer are revolved along column
Turn.
As another further improvement, it is provided with leading screw bearing on the orbital platform, the lead screw passes through axis
It holds and is connect with leading screw bearing.
As an improvement being provided with fixed pulley at the top and bottom of the chassis, the drawstring is successively bypassed at the top of chassis
With the fixed pulley of bottom.
As an improvement being provided with annular groove on the rail wheel outer ring surface, the track is connected in annular groove.
It prevents nut from rotating by groove and track clamping, so that nut is not rotation with the rotation of lead screw, can only rotate with it and preceding
After move.
As an improvement the driving device is motor, certain driving device may be to appoint including artificial mechanism etc.
The equipment that meaning mode drives lead screw to rotate.
The device for moderating force's instrument resistance having the beneficial effect that with above structure of the utility model,
Structure is simple to operation, changes traditional manual operating force measuring device tool resistance device, by controller come the resistance of moderating force's instrument
Multi-gear adjustment resistance, electrodeless adjustment resistance may be implemented in power size.In addition strength device can be realized by controller programming
The automation control of tool resistance.
