It presses and clamps, lift and unclamp, it is easy to operate.For the medium and small range sensors of 10N-100N, generally use 0.5-1kg's
Screw rod hand actuable clamping device, but clamping and release require to can be manually rotated screw rod every time, it is more troublesome.And for 10N and below
Small-range sensor, typically only by the area of the clamp clip for the screw rod hand actuable clamping device for reducing medium and small range sensors,
Reduce mode as tie down screw and screw rod hand actuable clamping device volume to mitigate the weight of screw rod hand actuable clamping device.
But for the operators using screw rod hand actuable clamping device, the clamping that measures each time and loosens, require
It can be manually rotated repeatedly, operation is more troublesome, influences the efficiency of test；And when operator's twistlock, once tension
The Unidirectional acting force of a horizontal direction can be then generated to clamping device, sensor can then be damaged by the torsional forces for being more than range
It is bad.For 10N and small-range sensor below, it is easy to which there is a situation where artificial damages.

It is semicircle, and two the second magnet 210 of magnet group 210a are symmetrical arranged.
In some other embodiment, above-mentioned magnet can be substituted using electromagnetic component.At this point, the first clamping component 100
First element including being located at second end 104, the second clamping component 200 include being located at the second element at the 4th end 204, and first yuan
Part and second element are electromagnetic component, alternatively, one of first element and second element are electromagnetic component, another one is magnetic
Iron.In this way, the polarity of electromagnetic component can be changed by changing the sense of current of electromagnetic component, to realize first element
It attracts each other with second element or mutually exclusive.At this point, first element and second element all can be one.
For example, the sense of current of first element can be fixed when first element and second element are electromagnetic component,
At this point, first element close to the side of second element polarity be the pole N, can by change second element sense of current come
Change second element close to the side of first element polarity so that second element close to the side of first element polarity in N
Switch between pole and the pole S.It is of course also possible to select the sense of current of fixed second element, and change the electric current of first element
Direction.
In another example when second element is electromagnetic component, first element is close to second element when first element is magnet
The polarity of side is the pole N, can change second element close to first element by changing the sense of current of second element
The polarity of side, so that polarity of the second element close to the side of first element switches between the pole N and the pole S.It is of course also possible to
Select second element for magnet, first element is electromagnetic component.
