[0028] A reduction motor 5 and a battery 6 are mounted on one side of the wire box 1, the battery 6 is a rechargeable battery, mainly used for supplying power to the reduction motor 5, and the reduction motor 5 is connected with the spool arranged in the wire box 1.The design of the reduction motor 5 usually comprises a motor and a gear box, a worm and gear reduction mechanism is designed in the gear box, the motor transmits power to the spool through the worm and gear reduction mechanism, thereby driving the spool to rotate, and the worm and gear reduction mechanism has a locking function, that is, the spool cannot rotate in the case of power failure.

[0029] A handle 7 is mounted at the rear of the wire box 1, and a button switch 8 for controlling the operation of the reduction motor 5 is arranged on the handle 7; the number of button switches 8 is two, one of which controls the forward rotation (or reverse rotation) of the reduction motor 5 to drive the spool to pay out the measuring line, and the other controls the reverse rotation (or forward rotation) of the reduction motor 5 to drive the spool to take up the measuring line.

[0030] A support frame 9 is fixed at the bottom of the wire box 1, a magnetic box 10 is fixed at the front end of the support frame 9, and a second adsorbing magnet 11 is fixed in the magnetic box 10.

[0031] As shown in Figure 3 , when the utility model is used, the magnetic box 10 is adsorbed on one end of the steel plate to be measured through the second adsorbing magnet 11, the reduction motor 5 is driven to pay out the measuring line 2 by operating the button switch 8, the worker pulls the measuring line 2 to the other end of the steel plate to be measured, and the first adsorbing magnet 4 is adsorbed and fixed on the edge of the steel plate to be measured, the adsorption positions of the first adsorbing magnet 4 and the second adsorbing magnet 11 are adjusted, so that the measuring line 2 is located at the most edge position of the two end sides of the steel plate to be measured.

[0032] In the embodiment, the front of the magnetic box 10 is open, so that the second adsorption magnet 11 in the magnetic box 10 can directly contact the steel plate to be measured, the suction force of the magnetic box 10 is improved, and the wire box 1 is stably fixed at the end of the steel plate.

[0033] In the embodiment, the bottom of the handle 7 is provided with a supporting screw rod 13, the supporting screw rod 13 is threadedly connected with the handle 7, the lower end of the supporting screw rod 13 is provided with a rubber pad, and the rubber pad at the lower end of the supporting screw rod 13 is adjusted to abut against the ground, so as to provide a support for the rear of the wire box 1.

Therefore, as shown in Figure 6 and 7 , the wire outlet hole 3 is designed as a rectangular hole arranged in the left-right direction, the tail end of the wire nozzle 12 is provided with a clamping groove 1201, and the clamping groove 1201 is clamped in the wire outlet hole 3. The wire nozzle 12 can be moved transversely along the clamping groove 1201, so that the position of the measuring line 2 is adjusted. The remaining structures in the embodiment are the same as those in embodiment two. The wire nozzle 12 is made of plastic material, and there is a certain frictional resistance between the clamping groove 1201 and the wire outlet hole 3, so that the wire nozzle 12 is not easy to slide after the position is adjusted.
