A use method of a flexible metal sheet cutting device comprises the following specific steps:

firstly, when a processing worker needs to cut a metal sheet, the cutting machine body 11 is held by a hand and is inclined, a cutting starting point of the metal sheet to be cut is placed between the upper and lower shearing blades 32, the processing worker manually rotates the rotary disc 13 according to the cut metal material and the working requirement, the rotary disc 13 rotates to drive the manual threaded shaft 39 to rotate through fixed connection, the manual threaded shaft 39 rotates to drive the movable connecting plate 37 to move leftwards through threaded connection, the movable connecting plate 37 moves leftwards and drives the working plate 64 to move leftwards through fixed connection, the working plate 64 moves leftwards and drives the cutting position of the shearing plate 31 to change, the effect of adapting to different working plates is achieved, meanwhile, the manual threaded shaft 39 rotates to drive the driving belt wheel 12 to rotate, the driving belt wheel 12 rotates to drive the driven belt wheel 17 to rotate through the transmission of the transmission belt 14, at the moment, the driven belt wheel 17 rotates and drives the movable threaded shaft 23 to rotate through fixed connection, at the moment, the movable threaded shaft 23 rotates and drives the supporting slide block 18 to move leftwards through threaded connection, at the moment, the supporting slide block 18 moves and drives the supporting working plate 44 to move through fixed connection, so that the position of the supporting working plate 44 is changed while the working plate 64 moves, at the moment, the supporting working plate 44 moves and enables the supporting rotating wheel 20 to be abutted and contacted with a workbench or a cutting working surface, and further, the integral support of the device is realized;

secondly, when the metal plate needs to be cut, the worker manually presses the switch plate 26, the switch plate 26 moves inwards under the elastic force of the switch spring 27, the switch plate 26 moves inwards and makes the switch plate 26 contact with the contact sensor 24, the contact sensor 24 starts the energy supply motor 51 through contact induction control, the energy supply motor 51 starts to drive the power rotating shafts 50 on the upper side and the lower side to rotate, the power rotating shafts 50 drive the rotating bevel gears 49 to rotate through fixed connection, the rotating bevel gears 49 drive the meshing bevel gears 47 to rotate through threaded connection, the meshing bevel gears 47 rotate and drive the rotating shaft 35 to rotate through fixed connection, the rotating shaft 35 drives the eccentric rotating wheel 36 to rotate through fixed connection, and the eccentric rotating wheel 36 deviates from the rotating center of the rotating shaft 35 and drives the eccentric rotating wheel 36 to start eccentric rotation, at the moment, the eccentric rotating wheel 36 pushes the supporting connecting rod 29 to move towards one side close to the symmetrical center in the process of eccentric rotation, at the moment, the supporting connecting rod 29 drives the shearing plate 31 to move relatively by overcoming the elastic force of the shearing spring 34 through fixed connection, at the moment, the shearing plate 31 moves relatively and is supported by the fixed supporting shaft 30 to drive the shearing plates 31 at two sides to be opened, and the supporting connecting rod 29 is moved back to the initial position again along with the rotation of the eccentric rotating wheel 36, so that the shearing plates 31 are opened and closed in an intermittent reciprocating manner, and metal cutting work is realized in the process;

thirdly, simultaneously, the switch board 26 moves inwards and drives the switch pull rope 28 and the connection pull rope 63 to be loose, at the moment, the rotating wire wheel 60 rotates under the action of the torsional elasticity of the torsion spring 61, at the moment, the rotating wire wheel 60 rotates and drives the turning shaft 42 to rotate through fixed connection, at the moment, the turning shaft 42 rotates and drives the turning plate 41 to turn through fixed connection, at the moment, the turning plate 41 turns and drives the turning support plate 16 to turn through fixed connection, at the moment, the turning cavity 46 with two sides turned to the outer side is used for facilitating a cutting person to hold the device by holding the turning support plate 16, so that the metal cutting work is more stable, meanwhile, the turning support plates 16 on two sides can also play a better protection effect, and the metal material which is ejected in the cutting process is prevented from causing harm to the working person;

fourthly, the rotating motor 52 is started to drive the supporting shaft 21 to rotate, the supporting shaft 21 rotates and drives the supporting runner 20 to rotate through fixed connection, the supporting runner 20 rotates and is abutted to a workbench or a working surface in a contact manner, the effect that the driving device is stable in the forward direction is further achieved, the cutting effect is improved through stable cutting feeding speed, and the cutting work of a processing worker is more convenient;

fifthly, when the metal plate in the vertical direction is cut, the turnover plate 45 can be supported by rotating outwards, the turnover plate 45 is supported by rotating outwards, the clamping plate 55 and the clamping cavity 58 are not clamped, the surface of the rotating friction plate 59 is abutted against the surface of the metal plate, the cutting direction and the cutting position are fixed in the subsequent cutting process, and the cutting efficiency of the metal plate is improved.

The invention has the beneficial effects that: the invention changes the positions of the working plate and the supporting working plate manually, adapts to the change of the working positions required by cutting different metal plates, is convenient for cutting personnel to hold the device by holding the overturning supporting plate through the rotating cavity with two sides overturned to the outer side, ensures that the metal cutting work is more stable, ensures that the overturning supporting plates on the two sides can also play a better protection effect, prevents metal materials ejected in the cutting process from causing harm to the working personnel, simultaneously realizes the stable forward effect of the driving device through the rotation of the supporting rotating wheel and the contact and the offset with the working table or the working surface in the working process, further improves the cutting effect through the stable cutting feeding speed, and ensures that the cutting work of processing personnel is more convenient.
