Preferably, hasp lock includes the lock for being fixed on locking lid, the axis pin on lock, is fixed in L bracket Lock tongue convex block and the lock body of lock is rotationally connected with by axis pin.

By using such scheme, specifically, during normal use lock can be fastened on by the lock body of setting The fixation to both is completed on tongue convex block, enabling prevent locking lid from opening, equipment operation is simple and convenient, adds equipment Practicality effect.

Preferably, being fixedly connected with rotating bar in the locking lid, pulley is rotatably connected in the rotating bar.

By using such scheme, the pulley in locking lid can be slightly compressed on the measurement line of rotating wheel, prevent rotating wheel The situation that line comes off from rotating wheel is measured during rotation during excessive velocities, adds the stabilizing effect of equipment.

Preferably, the reversing arrangement includes a U-shaped base being fixed in L bracket and is fixed on U-shaped base The major axis at both ends.

By using such scheme, reversing arrangement can be such that the measurement line of different directions is embedded in along the track of its restriction Into rotating wheel, can fixation measuring line the direction of motion so that left and right both direction come line can be changed back into Into rotating wheel, equipment operation is simple and convenient, adds the practicality effect of equipment.

Preferably, it is rotatably connected to rubber bush on the major axis.

By using such scheme, rubber bush is rotatably connected on major axis so that enable in use Measurement line is connected on the lateral wall of rubber bush, and measuring line during stretching measurement line is less likely to occur to wear, and improves The service life of equipment, adds the practicality effect of equipment.

In conclusion the utility model has the advantages that：

1. adding rubber mat material in the groove of rotating wheel, the friction of measurement line and rotating wheel is increased, overcomes and is surveying Only measurement line is mobile during amount and the problem of rotating wheel is motionless, add the accuracy of measurement；

2. reversing arrangement can be such that the measurement line of different directions is embedded into along the track of its restriction in rotating wheel, can consolidate The direction of motion of location survey amount line；

3. the rubber bush of reversing arrangement can increase the frictional force of measurement line and rubber bush, stability is added；

4. the pulley in locking lid can be slightly compressed on the measurement line of rotating wheel, when preventing excessive velocities when rotating wheel rotates The situation that measurement line comes off from rotating wheel；

5. the design of thread-like groove allows measurement line simultaneously wound in four thread-like grooves in rotating wheel, increase The attachment point of measurement line and rotating wheel, makes measurement line not easily to fall off on rotating wheel, improves the accuracy of measurement；

Fixed between 6.L shapes stent and locking lid by hasp lock, hasp lock is not only convenient but also quick and can open repeatedly Or close, while security is highly stable；

7. when hasp lock is opened, the area that the design of L bracket can expose rotating wheel is bigger, can be very convenient On rotating wheel place or take out measurement line.
