By arranging the cutting track 1 and the vehicle body 2, a cutting track can be effectively provided to the vehicle body 2 by installing the cutting track 1 on the metal plate, thereby realizing the cutting of the metal plate simply and effectively, and since the vehicle body 2 is small in size, it has sufficient portability.

[0017] As an improved specific implementation method, the upper side surface of the cutting track 1 is provided with a plurality of measuring grooves 3 arranged along the length direction of the cutting track 1, and a driving wheel 4 is rotatably provided on the side surface of the vehicle body 2, and a plurality of measuring blocks 5 are evenly distributed on the wheel surface of the driving wheel 4. When the driving wheel 4 rolls on the cutting track 1, the measuring blocks 5 are inserted into the measuring grooves 3. By setting the measuring grooves 3 and the measuring blocks 5, the cooperation of the two can be simply and effectively realized to realize the calculation of the moving distance of the vehicle body 2, thereby effectively realizing the control of the cutting length.

[0018] As an improved specific implementation method, a sensor is provided in the driving wheel 4, and the measuring block 5 is elastically and retractably installed on the driving wheel 4. When the measuring block 5 is squeezed back into the driving wheel 4 by the outside, the measuring block 5 triggers the sensor, and the sensor controls the vehicle body 2 to stop moving and cutting. Through the setting of the sensor, it can be effectively achieved that when the vehicle body 2 is about to exceed the cutting track 1, the vehicle body 2 can be effectively detected, thereby avoiding the problem of excessive cutting.

The sensor is an induction ring coaxial with the driving wheel 4, and the induction ring passes through all the mounting grooves 41. One end of the measuring block 5 facing the bottom of the mounting groove 41 is connected to the bottom of the mounting groove 41 through a spring, and a trigger column 51 is coaxially fixed to the end, and the end of the trigger column 51 facing away from the measuring block 5 is against the induction ring. When the measuring block 5 is squeezed back by the outside, the trigger column 51 squeezes the induction ring. Through the above structure, the measuring block 5 can be used without being inserted into the measuring groove 3 to detect whether the vehicle body 2 moves beyond the cutting track 1. The overall structure is simple and easy to implement. The induction ring of this embodiment can be implemented by pressure sensing.

[0020] As a specific implementation of the improvement, the cutting track 1 includes a left rail 11 and a right rail 12 and a plurality of connecting rods 13 for connecting the left rail 11 and the right rail 12.

The air pump is connected to the suction cups 14 on the lower sides of the left rail 11 and the right rail 12. By setting the suction cups 14 and the air pump, the air pump can be used to pump air inside the suction cups 14 to generate negative pressure in the internal space of the suction cups 14, thereby enabling the left rail 11 and the right rail 12 to be better installed on the metal plate. The air pump in this embodiment is a hand-pressure air pump.

The upper end of the push rod 21 is elastically hinged on the lower side of the vehicle body 2, and the lower end is used to resist the connecting rod 13, so that during the cutting process, the connecting rod 13 is pushed to move a distance and then reset. Through the arrangement of the above structure, the vehicle body 2 will be blocked by the connecting rod 13 during the cutting process. The connecting rod 13 is temporarily pushed away by the push rod 21 in this embodiment, and then after the cutting head completes the cutting, the connecting rod 13 is reset to achieve the effect of continuous cutting. The end of the connecting rod 13 in this embodiment is connected to the left rail 11 and the right rail 13 in a manner that a fixed block is provided in the left rail 11 and the right rail 13, a long groove is provided on the side of the fixed block, the end of the connecting rod 13 extends into the long groove, and the end is connected to the two ends of the long groove by a spring, so that the connecting rod 13 can slide elastically in the long groove.
