the force application tensioning mechanism (60) comprises a tension measurer (61) for displaying the tension, a mounting frame (62) for mounting and supporting, and a force application self-locking mechanism (63) arranged on the mounting frame (62);
one end of the tension measurer (61) is respectively connected with the free ends of the measured steel tape (10) and the standard steel tape (20), and the opposite end is connected with the force application self-locking mechanism (63);
the force application self-locking mechanism (63) is used for rotating under the action of external force so as to axially tighten the measured steel tape (10) and the standard steel tape (20) through the tension measurer (61), and reversely self-locking after the external force is eliminated.
9. The steel tape detecting apparatus of claim 8, wherein,
the tension measurer (61) comprises two spring scales, the two spring scales are arranged side by side, the first ends of the two spring scales are respectively connected with the free ends of the measured steel tape (10) and the standard steel tape (20), and the second ends of the two spring scales are respectively connected with the force application self-locking mechanism (63) through a traction rope (64).
10. The steel tape detecting apparatus of claim 9, wherein,
the force application self-locking mechanism (63) comprises two platform frame rollers (631) which are fixed at the top end of the mounting frame (62) at opposite intervals, two winding wheels (632) which are arranged between the two platform frame rollers (631), a rocker (633) which is respectively arranged at the outer sides of the two platform frame rollers and a bidirectional regulating mechanism (634);
the winding wheel (632) is connected with a bidirectional regulating mechanism (634) at the corresponding side through a connecting shaft (635) penetrating through a platform frame roller (631) at the corresponding side, and the bidirectional regulating mechanism (634) is connected with a rocker (633) at the same side;
two pulling ropes (64) connected with the two spring scales are respectively wound on corresponding winding wheels (632).
