The leather tape measure is made of fiberglass and PVC plastic, the alias is a fiber tape measure or a tape.
The tailor's foot is a leather tape measure.
Internal structure Related to the field of measuring tools, synchronous belt drive leather tape measure, is aimed at the public known as the leather tape, the internal structure of the coil with the spring reel and the size of the volume of the reel combined. If the size of the measurement of the leather tape is enlarged, it will produce radial tendency, and there is a kind of leather tape measure designed with less flexible technical problems.
The main point of design is that the front shell and the rear shell have a curved surface and a long longitudinal shape, and a short arc shape. In the front shell and the rear shell has the synchronous belt, the big gear, the small gear, the rotating drum, the rotation wheel; the large gear and the synchronous belt are arranged in the rotating drum, and the pinion and the synchronous belt are arranged on the rotating wheel extending the pinion pin shaft.
The leather tape measure is wound in the groove of the rotating wheel, and the rotating drum and the rotating wheel are set on the corresponding pin axis of the front shell and the rear housing. This kind of structure's leather tape measure aspect ratio produces the big change, uses the comfortable nimble, the take-up volume is more smooth, is the more ideal one kind of leather tape measure.
