Abstract
The utility model discloses a hand drill with an energy storage function. The hand drill comprises a drill rod and a drill bit rod. Threads are arranged at one end of the drill rod, a thread bushing is sleeved on the drill rod and is positioned at the threads, the drill bit rod is arranged at the other end of the drill rod, a drill bit is mounted on the drill bit rod, the adjacent ends of the drill rod and the drill bit rod are respectively rotationally nested in a sleeve handle, a clutch device is positioned between the end of the drill rod and the corresponding end of the drill bit rod in the sleeve handle, and an energy storage wheel is mounted on the drill bit rod. The hand drill has the advantages that when downwardly pushed, the thread bushing drives the drill rod to rotate via the threads, the drill rod drives the drill bit rod to rotate via the clutch device, a user holds the handle of the drill rod by a hand, the drill bit can be driven by the drill bit rod to perform drilling, inertia generated when the drill bit rod rotates can be increased by the energy storage wheel, accordingly, the labor intensity can be relieved, the hand drill is high in drilling accuracy and can be used conveniently and reliably, and the hole drilling machining efficiency can be greatly improved.
Description
Technical field
The utility model relates to a kind of hand drill.
Background technology
Existing hand drill is comprised of drilling rod, drillstock and drive rod, drillstock, the drilling rod of this hand drill axially link together, axial length is longer, carry, use inconvenience, and connect by simple axle suit, frictional resistance is large, and the focus of work is unstable, process velocity is slow, and processing quality is poor.
Summary of the invention
It is higher that technical problem to be solved in the utility model is to provide a kind of working (machining) efficiency, can effectively reduce labor intensity, and easy to use and reliable Manual energy-storage bores.
For solving the problems of the technologies described above, the technical solution of the utility model is: Manual energy-storage bores, comprise drilling rod and drill bit shaft, one end of described drilling rod is provided with screw thread, on described drilling rod, be positioned at described screw thread place and be set with thread bush, the other end of described drilling rod is provided with drill bit shaft, in described drill bit shaft, drill bit is installed, the adjacent end portion of described drilling rod and drill bit shaft respectively turning set is contained in sleeve handle, between described drill rod end in described sleeve handle and described drill bit shaft end, be provided with arrangement of clutch, accumulation of energy wheel is installed in described drill bit shaft.
As preferred technical scheme, described arrangement of clutch comprises the active ratchet being located on described drilling rod, and described drilling rod is provided with the driven ratchet coordinating with described active ratchet.
As preferred technical scheme, described drilling rod and drill bit shaft by bearing respectively turning set be contained in described sleeve handle.
Owing to having adopted technique scheme, Manual energy-storage bores, comprise drilling rod and drill bit shaft, one end of described drilling rod is provided with screw thread, on described drilling rod, be positioned at described screw thread place and be set with thread bush, the other end of described drilling rod is provided with drill bit shaft, in described drill bit shaft, drill bit is installed, the adjacent end portion of described drilling rod and drill bit shaft respectively turning set is contained in sleeve handle, between described drill rod end in described sleeve handle and described drill bit shaft end, be provided with arrangement of clutch, accumulation of energy wheel is installed in described drill bit shaft; When promoting, thread bush drive drilling rod to rotate by screw thread downwards, drilling rod drives drill bit shaft to rotate by arrangement of clutch, with hand, grip drilling rod handle, drill bit bores under the drive of drill bit shaft, accumulation of energy wheel has increased inertia when drill bit shaft is rotated, and alleviated labour intensity, and boring accuracy is higher, greatly improved Drilling operation efficiency, easy to use and reliable.
accompanying drawing explanation
Fig. 1 is the structural representation of the utility model embodiment;
In figure: 1-drilling rod; 2-screw thread; 3-thread bush; 4-drill bit shaft; 5-drill bit; 6-accumulation of energy wheel; 7-sleeve handle; 8-is ratchet initiatively; The driven ratchet of 9-.
The specific embodiment
As shown in Figure 1, Manual energy-storage bores, comprise drilling rod 1 and drill bit shaft 4, one end of described drilling rod 1 is provided with screw thread 2, on described drilling rod 1, be positioned at described screw thread place and be set with thread bush 3, the other end of described drilling rod 1 is provided with drill bit shaft 4, in described drill bit shaft 4, drill bit 5 is installed, the adjacent end portion of described drilling rod 1 and drill bit shaft 4 respectively turning set is contained in sleeve handle 7, between described drilling rod 1 end in described sleeve handle 7 and described drill bit shaft 4 ends, be provided with arrangement of clutch, accumulation of energy wheel 6 is installed in described drill bit shaft 4.
Described arrangement of clutch comprises the active ratchet 8 being located on described drilling rod 1, and described drill bit shaft 4 is provided with the driven ratchet 9 coordinating with described active ratchet 8.
Described drilling rod 1 and drill bit shaft 4 by bearing respectively turning set be contained in described sleeve handle 7.
During boring, when promoting, thread bush 3 drive drilling rod 1 to rotate by screw thread 2 downwards, drilling rod 1 drives drill bit shaft 4 to rotate by arrangement of clutch, with hand, grip sleeve handle 7, drill bit 5 bores under the drive of drill bit shaft 4, and accumulation of energy wheel 6 has increased inertia when drill bit shaft 4 is rotated, alleviated labour intensity, and boring accuracy is higher, has greatly improved Drilling operation efficiency, easy to use and reliable.
More than show and described basic principle of the present utility model, principal character and advantage of the present utility model.The technical staff of the industry should understand; the utility model is not restricted to the described embodiments; that in above-described embodiment and description, describes just illustrates principle of the present utility model; do not departing under the prerequisite of the utility model spirit and scope; the utility model also has various changes and modifications, and these changes and improvements all fall within the scope of claimed the utility model.The claimed scope of the utility model is defined by appending claims and equivalent thereof.
