Description
Technical field
The present invention relates to a kind of magnetic power-assisted hand drill, relate to a kind of any power source that do not use specifically, utilize permanent magnet magnetic force each other,, belong to the hardware ﹠ tools field by the hand drill of gear drive as power resources.
Background technology
In the process that engineering construction and industrial products are assembled, keep in repair, packed, usually need material surface is implemented boring or carried out holding screw by hand drill, existing portable boring bar tool is normally used power-actuated electric hand drill at present, and common torch is drilled with external AC power supply electric hand drill and rechargeable dc source electric hand drill.The shortcoming of external AC power supply electric hand drill is: must there be AC power the job site, need to connect long power lead, and when far away, the higher position construction of distance power supply or when running into power-off condition and taking place, electric drill can't use; In addition, AC power electric drill noise when work is big, and environment is had bigger noise pollution, consume more electric energy.The shortcoming of rechargeable dc source electric hand drill is: the torsion of electric drill is too little, can only punch on than veneer, can not punch on metallic plate, and the effective storage life of its battery is too short, generally can only continuous operation 1-3 hour, after the running down of battery, can not carry out work again.More than two kinds of electric hand drills because inside is provided with motor and coil, accessory is many, overall structure is comparatively complicated, unstable properties especially when electric hand drill is in the overload operation state, is easy to cause motor to damage, so the service life of above-mentioned two kinds of electric drills is too short, general one electric drill using about 6-10 month, will scrap basically, need purchase new electric drill and use.In addition, more than two kinds of electric drills all can not be under water or the work down of comparatively moist environment, otherwise the motor of electric drill can be damaged.
Summary of the invention
The objective of the invention is defective at the background technology existence, design provides a kind of magnetic power-assisted hand drill, this hand drill in use need not driven by power, only depend on the permanent magnetic iron magnetic force each other that is installed in the hand drill enclosure interior just can provide the hand drill running required power, thereby broken away from dependence to electric power, this hand drill is without any need for power supply and power lead, save the energy, accurate positioning, stable performance, torsion is big, jewel hole not only can punch on any plank, the jewel hole that can also on various metallic plates and adamantine corrosion resistant plate, punch, vibrations are little during boring, noise is little; This hand drill can carry out operation in water He under any wet environment, can not influence the performance of hand drill function; Because this hand drill inside does not have motor, need not to carry out special maintaining, complete machine is in light weight, long service life, portably use conveniently, can be widely used in industrial and mining enterprises, industrial production, product processing, electric equipment maintenance, space equipment maintenance, every field such as underwater installation maintenance such as steamer, submarine.
In order to achieve the above object, the present invention realizes by following technological means:
