[0002] The jigsaw consists mainly of a frame and a cutting assembly. Figure 5 The cutting assembly includes a mounting frame, a plurality of rollers 62 rotatably arranged on the mounting frame, and two sets of retractable wire systems 7. The cutting wire 5 is led out from the first set of retractable wire system 7 and then reciprocatedly wound on the roller roller 62 to form a cutting mesh 511, and the end of the cutting wire 5 is connected to the second set of retractable wire system 7. The roller roller 62 is driven by a rotary drive motor to rotate forward and reverse. When the roller roller 62 rotates forward and reverse, it can drive the cutting mesh 511 to reciprocate and saw the cutting material. During the cutting process, the first set of retractable wire system will continuously release new cutting wires, and the second set of retractable wire system will continuously retract the worn-out old wires. The roller roller on the wire saw is a consumable item that needs to be disassembled and replaced after a certain period of time. The roller roller in the related art is locked with the main and auxiliary bearings fixed at both ends by a bolt structure. Therefore, when disassembling the roller roller, it is necessary to remove the bolt structure first, and then remove the roller roller, which is inconvenient to disassemble and assemble.
