The slide rail 404 is slidably connected in the guide groove. Gear grooves are respectively provided on the slide blocks 403 on both sides of the guide groove. The gear grooves are respectively meshed and connected with the third gear 405. One side of the gear groove The operating table 1 is provided with a mounting groove, and the third gear 405 is rotatably connected in the mounting groove. An operating shaft 406 is fixedly connected to the rotating shaft of the third gear 405, and the operating shaft 406 is rotatably connected in the operating table 1. One end of the operating shaft 406 is rotatably connected to the U-shaped rotating frame 407. A movable groove is provided on the operating table 1 on one side of the U-shaped rotating frame 407, and the U-shaped rotating frame 407 is movably connected in the movable groove. An operating handle 408 is fixedly connected to the U-shaped rotating frame 407, and an operating hole 410 is provided on the arch plate 409. The handle rod of the operating handle 408 is slidably connected in the operating hole 410. Both ends of the arch plate 409 are fixedly connected to the operating table 1. In this embodiment, the user can manually adjust the working mode. Taking the conversion from the pipe 8 clamping mode to the pipe 8 cutting and grinding mode as an example, the specific operation is as follows:; First, pull the operating handle 408 to rotate the operating handle 408 from one end of the operating hole 410 to the other end. At this time, the operating handle 408 drives the operating shaft 406 to rotate through the U-shaped rotating frame 407, and the operating shaft 406 drives the third gear 405 to rotate. The third gear 405 drives the slide block 403 to slide along the slide rail 404 through the meshing action of the gear groove. The slide block 403 drives the connecting frame 315 to move to one side through the support rod 402. The connecting frame 315 simultaneously drives the movable block 308 to move, and the movable block 308 drives the sliding sleeve 305 to synchronously displace to one side (in the displacement direction of the first driving gear 301 to the second driving gear 302). In this process, the inner spline 306 of the sliding sleeve 305 on one side of the second driving gear 302 is separated from the outer spline 304 on the opposite side, so that the power connection between the second driving gear 302 and the driving shaft 309 is disconnected, and the sliding sleeve 305 on the first driving gear 301 is disconnected. In the sliding sleeve 305 on the side, the inner spline 306 and the outer spline 304 on the opposite side slide and mesh with each other. At this time, when the driving motor 314 drives the driving shaft 309 to rotate, the driving shaft 309 drives the spline shaft 311 to rotate, the spline shaft 311 drives the spline sleeve 310 to rotate, and the spline sleeve 310 drives the sliding sleeve 305 to rotate. When the outer spline 304 meshes with the inner spline 306, the sliding sleeve 305 drives the sliding sleeve shaft 303 to rotate, and the sliding sleeve shaft 303 drives The connected first driving gear 301 rotates, and the first driving gear 301 drives the cutting and grinding device 4 to perform cutting and grinding operations. When the external spline 304 and the internal spline 306 on the other side are separated from each other, the spline sleeve 310 also drives the sliding sleeve 305 to rotate. However, since the external spline 304 and the internal spline 306 are staggered and separated from each other, the sliding sleeve 305 on this side rotates relatively on the sliding sleeve shaft 303, so it cannot drive the second driving gear 302 to rotate.

[0027] See also Fig.11 In one embodiment of the present invention, slots 411 are respectively provided at both ends of the operating hole 410, and the operating handle 408 is respectively snap-connected in the slots 411.

Limiting slots are respectively provided on both sides of the notch of the slots 411, and connecting rods 413 are rotatably connected in the limiting slots. A torsion spring 414 is provided at the rotating connection of the connecting rod 413, and the other end of the connecting rod 413 is fixedly connected to the limit blocks 412. The limit blocks 412 are cylindrical, and the limit blocks 412 are respectively located on both sides of the notch of the slots 411. After the operating handle 408 is flipped to one end of the operating hole 410, it can be snap-connected in the slots 411. The operating handle 408 in the slots 411 can be blocked by the limiting components to prevent the operating handle 408 from sliding in the operating hole 410 during operation.
