Technical problem to be solved in the utility model is to provide a kind of solid center bit, handle and drill body are threaded connection and reach detachable, and handle, at its lower end is provided with cross spiral cutter, reach the double-purpose functional of boring and dismounting, drill body inside is provided with hydraulic structure, can reach the effect of energy and labour saving.
For achieving the above object, the utility model provides following technical scheme: a kind of solid center bit, comprise handle and drill body, described handle tip is set to sphere structure, external thread structure is set to outside handle, handle, at its lower end is provided with cross spiral cutter, described drill body inside top is set to female thread structure, drill body inside is provided with hydraulic structure, drill body outer end is provided with screw blade, is provided with spiral row and cuts groove outside drill body, and described drill body inside is provided with oil pocket, be provided with conical blade bottom described drill body, described conical edge of a knife lower end is provided with knife needle.
Preferably, the sphere structure of described handle tip is set to soft molding material, especially elects elastomeric material as.
Preferably, described hydraulic structure is primarily of carriage release lever and swingle composition, described carriage release lever inside is provided with screw rod, screw rod is threaded connection in carriage release lever inner, fixing spring is provided with outside swingle, screw rod driven member and bearing are by interference fit, and bearing is threaded connection on swingle top.
Preferably, described knife needle selects high-hardness metal material, especially elects aluminum alloy materials as.
Preferably, the oil-in of described oil pocket is located at drill body hydraulic structure place, and rooved face is cut by the outlet row of being located at.
The beneficial effect of above technical scheme is adopted to be: the drill body inside of this solid center bit is provided with hydraulic structure, hydraulic structure group will be made up of carriage release lever and swingle, hand carriage release lever, by the cooperation transmitting force of screw rod and screw rod driven member, makes bit and moves downward, complete boring, such processing is energy-conservation and laborsaving, is provided with spring simultaneously, makes hole machined more accurate in carriage release lever inside, be provided with oil pocket in drill body inside in addition, reach lubrication; The handle of this solid center bit and drill body are threaded connection and reach detachable, and handle, at its lower end is provided with cross spiral cutter, reach boring and the dismounting double-purpose functional of solid center bit.
