The working principle of the invention is as follows:

1. when continuously drilling the wall body of the pipeline, firstly pulling the locking frame 34 upwards, making the pipeline to be processed enter from the feeding ring 33 and penetrate out from the pressing ring 28, at the moment, the pipeline is positioned on the arc-shaped placing groove 202 and slightly pressed by the top plate of the locking frame 34, starting the drilling motor 23, when the working rod 12 is pulled upwards, the main driving rod 21 descends, the main driving rod 21 drives the two driving plates 211 and the pressing short plate 214 to descend, the driving plate 211 drives the pressing long plate 216 to descend, the pressing long plate 216 presses the bending movable plate 391 downwards, as the bending movable plate 391 is elastically connected in the fixed side plate 39, the lifting driving plate 35 is subjected to downward elastic tension, so that the locking frame 34 is also subjected to downward elastic tension, at the other side, the pressing short plate 214 presses the buffer plate 29, the descending of the buffer plate 29 also causes the horizontally movable convex plate 274 to be subjected to downward elastic tension, finally, the compression ring 28 and the locking frame 34 generate downward pressure on two ends of the pipeline so as to realize compression fixation of the pipeline, and the drill bit 24 starts to drill the upper end wall body of the pipeline after the pipeline is compressed and fixed;

2. after drilling, the drill bit 24 is reset under the action of the long return spring 213 and the short return spring 212, then the working rod 12 is pressed downwards, the main driving rod 21 rises, at the moment, the driving plate 211 rises to drive the vertical supporting plate 22 to rise, the vertical rack 222 rises to drive the driving gear 26 to rotate clockwise, at the moment, the transmission gear 25 also rotates clockwise to drive the moving frame 32 to move backwards, in the moving process, due to the action of the elastic pressure spring 322, the pipeline is slightly pressed by the top plate of the locking frame 34 all the time, therefore, the feeding ring 33 and the locking frame 34 are matched to drive the pipeline to move backwards together to realize feeding, the lifting driving plate 35 continuously approaches the driving ejecting ball 363 when moving backwards, until the driving ball 363 pushes up the lifting driving plate 35 and is clamped in the strip-shaped clamping groove 352, at the moment, because of a certain distance of the lifting driving plate 35 rising, the locking frame 34 also rises, at this time, the pipeline is not under the pressure of the locking frame 34, then when the working rod 12 is reset, the transmission plate 211 descends, the vertical support plate 22 descends, the vertical rack 222 descends to drive the drive gear 26 to rotate anticlockwise, the moving frame 32 moves forwards, in the whole process that the lifting transmission plate 35 moves forwards, as the transmission top ball 363 is always clamped in the strip-shaped clamping groove 352, the feeding ring 33 and the locking frame 34 cannot drive the pipeline to move in the resetting process, the moving block 362 moves forwards until being limited by the adjusting moving groove 361, the transmission top ball 363 is separated from the strip-shaped clamping groove 352, at this time, the moving block 362 resets under the action of the moving reset spring 364, the lifting transmission plate 35 is squeezed by the elastic pressure spring 322 again to enable the locking frame 34 to compress the pipeline again, and the process that the main drive rod 21 ascends and resets realizes that the pipeline advances for a certain distance;

3. when adjusting the hole interval according to actual conditions, can make accommodate the screw 38 rotate through rotating adjusting nut 381, thereby adjust the displacement of feeding regulating block 37, the position of transmission top pearl 363 in regulation removal recess 361 is finally decided, for example, adjust a little earlier with feeding regulating block 37, transmission top pearl 363 is a little closer apart from the distance of lift driving plate 35 this moment, can earlier cooperate with transmission top pearl 363 when lift driving plate 35 moves backward, thereby make earlier the release of locking frame 34, even if locking frame 34 continues forward this moment, the pipeline can not continue to move again, thereby the displacement of the feeding at every turn of pipeline has been adjusted, finally, the adjustment to the hole interval has been realized.
