Description of the embodiments

The utility model is described in further detail below with reference to the drawings and the detailed description.

Referring to fig. 1 to 6, the storage module of the tape measure band comprises a main frame 1, a fixed wheel set 2, a movable wheel set 3 movable relative to the fixed wheel set 2 and a wheel set driving module for pushing the movable wheel set 3 are arranged on the main frame 1, the movable wheel set 3 is movably supported by guide posts 100 arranged on two sides, the fixed wheel set 2 and the movable wheel set 3 respectively comprise a plurality of groups of storage wheels 4 which are rotatably arranged on the fixed wheel set, a feeding wheel 5 is arranged on the front side of the fixed wheel set, and a pressing wheel 6 for pressing the tape measure band is arranged on one side of the feeding wheel 5. The device comprises a pinch roller adjusting mechanism 7 for adjusting the pinch roller, and comprises a rotating shaft seat 70, a rotating shaft 71 rotatably supported in the rotating shaft seat 70, an eccentric shaft 72 extending out of the rotating shaft seat 70 is arranged at the front end part of the rotating shaft 71, a hinge arm 73 is fixed at the rear end part of the rotating shaft 71, and the hinge arm 73 is pushed by a driving cylinder 74.

In the above structure, the hinge arm 73 can be driven by the cylinder, however, the rotating shaft 71 is rotated, so as to drive the eccentric shaft 72 at the end of the rotating shaft 71, and the distance between the feeding wheel 5 and the pinch roller 6 at the end of the eccentric shaft 72 can be adjusted, so that the friction force of the measuring tape is controlled, and the slipping phenomenon is prevented when the measuring tape is synchronous with the feeding wheel. The rear end portion of the rotating shaft 71 can directly extend into the main frame 1, however, the cylinder and the hinge arm are arranged in the main frame to drive the rear end of the rotating shaft 71, so that the driving device for the pinch roller 6 can not occupy the space of the working end surface of the main frame at all, and in addition, the space between the pinch roller 6 and the feeding roller 5 is more favorably controlled by pushing the hinge arm through the cylinder and controlling the eccentric shaft 72 of the front section of the rotating shaft.
