An upsetting position is arranged on the pier hammer 9.

[0026] In this embodiment, the rotating mechanism includes a mounting plate 8 disposed inside the machine housing 1, a rotating shaft 12 welded to the right side of the mounting plate 8, a reduction motor 11 fixedly mounted on the outside of the slide 6, a worm wheel 13 fixedly mounted on the outer surface of the rotating shaft 12, and a worm 14 fixedly mounted on the output shaft of the reduction motor 11 and meshing with the worm wheel 13. The reduction motor 11 is started to drive the worm 14, and the worm 14 rotates and meshes with the worm wheel 13 to drive the mounting plate 8 through the rotating shaft 12, so as to realize the replacement of several pier hammers 9, which not only reduces the occupied space, but also realizes the replacement of several pier hammers 9.

[0027] A feed port 2 is provided on the left side of the machine housing 1, and a connection block 10 fixed to the right side of the slide 6 is fixedly installed at the output end of the hydraulic telescopic rod 7.

The installation of the limit seats 15 ensures that the rotating shaft 12 rotates stably and improves the adjustment of the pier hammer 9. A wiring hole is opened in the machine housing 1.

[0029] Embodiment 2:

[0030] See also Figure 4 On the basis of the first embodiment, a clamping mechanism for clamping steel bars is provided inside the machine housing 1, and the clamping mechanism includes a telescopic electric cylinder 3, a first clamping plate 4 and a second clamping plate 5; the number of the telescopic electric cylinders 3 is two, and the two telescopic electric cylinders 3 are symmetrical and installed on the outside of the machine housing 1 by bolts, and the inside of the opposite side of the machine housing 1 is provided with through holes, and the output ends of the two telescopic electric cylinders 3 extend to the inside of the machine housing 1 through the through holes.
