The utility model discloses an easily follow device that bores core sampler drill bit and take out with core appearance has the opening on the safety cover of device, it includes five on -dismountable parts to bore core remove device: connecting axle, radial axis of rotation, axis of rotation fixed part, drill bit wall and press the core box and two can dismantle parts: handle and vertical power transmission shaft rotate. The top that the connecting axle is located the drill bit becomes integrative with brill core sampler leg joint, and the lower extreme and the bigger drill bit wall of diameter of connecting axle are a whole, radial axis of rotation is passed perpendicularly and is fixed on the connecting axle along the connecting axle diametric(al), is equipped with two dogtooth wheels in the just radial axis of rotation, have concave tooth on two vertical power transmission shaft's the face, this concave tooth with epaxial protruding gear engagement radially rotates, provide power for the lift of vertical power transmission shaft, two vertical power transmission shaft top -down stretch into and press the core box bottom, press the core box outer wall to have vertical tongue, can make and press three the vertical recess vertical slips of core box along the drill bit wall. This bores core sampling device, makes core appearance receive perpendicular pressure and drop, core appearance take out laborsaving, save time, high -efficient, swift, improved test data's accuracy.
