The invention relates to low-disturbance soil pile forming equipment and a construction technology, and relates to the technical field of pile foundation construction, and the low-disturbance soil pile forming equipment comprises a stand column, a drilling system and a drilling power assisting device. Under the synergistic effect of low-pressure drilling and the drilling power assisting device and in combination with an intermittent stamping mode generated by the push-pull assembly, formation resistance is efficiently broken through on the premise of low disturbance; and meanwhile, the guiding and linkage assembly is used for achieving automatic lateral stabilization in the drilling process, deflection is effectively restrained, the pile forming perpendicularity is guaranteed, and the technology has the advantages of being small in construction disturbance, low in noise, free of slurry discharging, high in pile forming quality, high in equipment adaptability and the like, and is suitable for efficient low-disturbance construction in narrow sites.

The utility model discloses a kind of embroidery machine head with double-sliding-block transmission needle bar frame, including head shell, needle bar frame is slidably connected by guide rail device in head shell side edge, needle bar frame includes integrally formed first connecting arm and second connecting arm, the guide rail device includes guide rail, guide rail cooperatively connects first slider and second slider, first slider connects first connecting arm, second slider connects second connecting arm, the first connecting arm includes first connecting rod and first connecting block mutually at longitudinal direction ninety degrees included angle, ninety degrees included angle cooperatively connects first slider, the second connecting arm includes second connecting rod and second connecting block mutually at longitudinal direction ninety degrees included angle, ninety degrees included angle cooperatively connects second slider.The utility model is connected by two sliders two connecting arms of needle bar frame respectively, and the stability of needle bar frame relative to head sliding is improved by the clamping type connection of ninety degrees included angle, and the stability of single slider structure is better relative to long distance.
