Lower steady stripping causes the first connector 210 can be with respect to the first rolling element 130 certainly under a stretching force in steel tube surface to be measured
By sliding, the second connector 310 can opposite second rolling element 140 it is free to slide, thus can ensure that in test process, direction of pull
Always it perpendicular to the surface of steel pipe sample to be measured and radially extends.In this way, above-mentioned test fixture can be realized to direction of pull
Controllable with peeling rate, and peeling rate vertical with steel tube surface is uniform always for pulling force during ensureing anticorrosive coating peeling,
Conducive to the accuracy for improving test result, meet testing requirement, and easy to operate, laborsaving.
Each technical characteristic of embodiment described above can be combined arbitrarily, to make description succinct, not to above-mentioned reality
It applies all possible combination of each technical characteristic in example to be all described, as long as however, the combination of these technical characteristics is not deposited
In contradiction, it is all considered to be the range of this specification record.
Embodiment described above only expresses the several embodiments of the utility model, and description is more specific and detailed,
But therefore it can not be interpreted as the limitation to utility model patent range.It should be pointed out that the common skill for this field
For art personnel, without departing from the concept of the premise utility, various modifications and improvements can be made, these are belonged to
The scope of protection of the utility model.Therefore, the protection domain of the utility model patent should be determined by the appended claims.
