then, the driving motor 33 provides power to correspondingly move the eccentric connecting sliding block 34 along the sliding track of the upper engaging member 31, and at the same time, the upper engaging member 31 is driven to move along the vertical direction in the upper sliding groove 302, and at the same time, the upper engaging member 31 drives the second crank 36 to swing around the supporting hinge shaft 38 rod through the first crank 35, so that the third crank 337 drives the lower engaging member 32 to move in the vertical direction, that is, the upper engaging member 31 and the lower engaging member 32 realize a relative approaching or relative distancing motion under the power, and during the relative distancing motion, the upper blank area 5 and the lower blank area 6 of the sample 1 to be tested can be relatively pulled apart, so that the two portions of the colloidal material 3 originally stuck together are gradually pulled apart, and the sample 1 to be tested is observed after being pulled apart.

Through the power that driving motor provided, corresponding make eccentric connection sliding block move about and reciprocate, then make the fastener move about when reciprocating, go up the fastener and drive down the fastener through a plurality of crank rods that connect gradually simultaneously and move. And this kind of structure can make last fastener and lower fastener realize relatively approaching movement and the relative motion of keeping away from, and this kind of removal effect appears on last fastener and lower fastener simultaneously, and it is same power carry out the output, just so control more easily the action of pulling open to the sample that awaits measuring of middle part, and owing to upwards pulling and pulling down have fine homogeneity or simultaneity, just so make the action of pulling open to the pressing position of the colloidal material of flexible body more unified, and then make the test effect more accurate.

The third embodiment:

the driving motor 33 is connected with a control host, the control host monitors the output power or output power of the driving motor 33, and the output power is converted into the physical bonding coefficient of the colloidal material 3 of the sample 1 to be detected;

the test method comprises the following steps: the control host machine sends a signal to enable the driving motor 33 to provide power, provides output power gradually increased from small to large, cannot pull the colloidal material when the output power is small, can smoothly separate the two parts of the colloidal material 3 when the output power exceeds a certain critical value, and can convert the relative size of the physical parameters of the adhesiveness of the colloidal material on the flexible body 2 by recording the output power of the critical value.

Through the monitoring function of the control host, the output power can be monitored or changed, the power for pulling the test sample is monitored and calculated, the pulling action for the connection position of the flexible body can be just realized under which power, namely, the power is gradually increased, or the change condition of the current is correspondingly monitored, the increased current is gradually given, the power required for pulling can be determined after the pulling action for the connection position of the colloidal material is realized at the critical point, and the physical parameter of the colloidal material can be quantitatively converted according to the power parameter or the current parameter, the physical parameter gets rid of the defect of visual observation, and the caking physical parameter of the colloidal material is relatively determined from quantitative data change.
