2. A process for producing a steel tape according to claim 1, wherein: the shifting lever (36) is rotatably arranged at the side end of the detection bracket (18) and is positioned at the lower side of one side, close to the second mounting frame (21), of the sliding rod (29).
3. A process for producing a steel tape according to claim 2, wherein: the sliding rod (29) comprises a semi-cylindrical bottom rod (31) and a semi-cylindrical positioning rod (32) which is rotatably connected to the side end of the bottom rod (31), the positioning rod (32) and the bottom rod (31) are attached to form the cylindrical sliding rod (29), and the end of a steel bar in the steel tape is clamped between the positioning rod (32) and the bottom rod (31).
4. A process for producing a steel tape according to claim 3, wherein: the magnetic attraction piece (34) is arranged at one side end, far away from one end of the rotating shaft center, of the positioning rod (32) and close to the bottom rod (31), and an iron piece (33) for magnetic attraction of the magnetic attraction piece (34) is arranged at one side end, close to the positioning rod (32), of the bottom rod (31).
5. A process for producing a steel tape according to claim 1, wherein: and a rotating ring (37) for abutting and sliding the shifting lever (36) is rotatably arranged at one end of the shifting lever (36) far away from the detection bracket (18).
6. A steel tape produced by the production process as claimed in any one of claims 1 to 5, wherein: including shell body (13), coiling be fixed in coil spring piece (14) and the coiling of shell body (13) inside center in and be convoluteed in shell body (13) and be fixed in chi strip (15) of coil spring piece (14) one end, chi strip (15) are made by the billet.
