For achieving the above object, the invention provides a kind of manual hole digger, wherein, comprising: square frame, it is for hollow structure and lower end is provided with opening; The top of the inner chamber of this square frame has been horizontally set with one first frame plate, and the bottom symmetry of the inner chamber of this square frame is convexly equipped with two the second frame plates; Lifting platform, it is arranged in the inner chamber of described square frame in the mode that can slide up and down; Motor, it is fixedly installed on the bottom of described lifting platform; Drill bit, its upper end is connected with described motor; Screw mandrel, the bottom of two these screw mandrels is rotatably sheathed on described two the second frame plates respectively, and the top of these two screw mandrels is rotatably sheathed on described first frame plate respectively; Described lifting platform is provided with two screws to be connected with a joggle with these two screw mandrels; First gear, the upper end of described two screw mandrels is located at by two these the first gears respectively fixed cover; Driving shaft, its lower end is rotatably sheathed on described first frame plate, and the upper end of this driving shaft is piercing in the top of described square frame; Second gear, its fixed cover is located at the bottom of described driving shaft, and the both sides of this second gear are connected with a joggle with described two the first gears respectively; And handwheel, it is fixedly installed on the upper end of described driving shaft.
Preferably, in technique scheme, on described handwheel, eccentric setting has one handle.
Preferably, in technique scheme, the inner chamber of described square frame is arranged with two chutes, and the two ends of described lifting platform respectively active card are embedded in these two chutes.
Preferably, in technique scheme, the diameter of described second gear is greater than the diameter of described first gear.
Compared with prior art, the present invention has following beneficial effect:
The present invention drives the first gear and the second pinion rotation by rotating handwheel, thus is controlled the lifting of lifting platform by the rotation of screw mandrel, and with the process of digging pit of Non-follow control drill bit, it is simple and light, rapid operation, common agricultural to be suitable for.
