[0022] In this embodiment, a slider 15 is fixedly connected to the bottom of the transmission box 4 , a slide groove 6 is arranged parallel to the top of the base 1 , and the slider 15 is slidably connected inside the slide groove 6 .

[0023] In this embodiment, a support plate 10 is fixedly connected to the right end of the second motor mounting plate 7 , a guide block 9 is fixedly connected to the top of the support plate 10 , and the drill rod 11 passes through the guide block 9 to connect to the drilling rig 8 .

[0024] In this embodiment, a cavity is disposed on the top of the transmission box 4 , a hydraulic cylinder mounting plate 14 is disposed on the bottom of the cavity, and a hydraulic cylinder 12 is fixedly connected to the top of the hydraulic cylinder mounting plate 14 .

[0025] In this embodiment, the bottom of the second motor mounting plate 7 is arranged at the top of the cavity, and a pin seat 13 is fixedly connected to the bottom of the second motor mounting plate 7.
