Abstract

The utility model relates to an electric drill which is especially suitable for hand drills in families and occasions with no power. The pocket drawing hand drill comprises a wooden handle, a fixed shaft, a rotary sleeve, an axial interstage sleeve, rollers, a drill chuck, a locking cap and a rope pulling rod, wherein, the fixed shaft is composed of stepped shafts provided with major and minor diameter shafts; an inner shoulder whose upper and lower surfaces are conical surfaces is arranged on the middle part of the bore of the rotary sleeve; the small diameter shaft of the fixed shaft is fixed into the wooden handle. The bottom of the major diameter shaft is supported on the roller which is arranged on the conical surface of the rotary sleeve, and the outer surface of the major diameter shaft is movably matched with the bore of the rotary sleeve. Thus, the pocket drawing hand drill with the advantages of simple structure, small size and low cost is not electrically driven.

Description

Pocket drawing hand drill

The utility model relates to a kind of electrician's drill, is particularly suited for the manual electrician's drill of family and non-transformer occasion.

At present, common electrician's drill is small-sized electric hand drill, complex structure not only, and the cost height, and be unsuitable for the non-transformer occasion, use limited.

In view of this, the purpose of this utility model provides a kind of pocket tractive and bores, and bores with manual tractive rotating shaft and the manual of rotating shaft top manual compression power.

The purpose of this utility model is achieved in that it comprises wood handle, fixed axis, rotaring sleeve, axial shelves cover, ball, drill chuck, locking cap and rope stayed pole, wherein, fixed axis is that the multidiameter by large and small diameter shaft forms, and the endoporus middle part of rotaring sleeve has the upper and lower interior shoulder of inner conical surface that is; The small diameter shaft of fixed axis be fixed on wood in, and the bottom of major diameter axle is supported on the rotaring sleeve on the ball above the inner conical surface, and major diameter axle outer surface cooperates with the activity of rotaring sleeve endoporus.

Above-mentioned axial shelves cover is connected the rotaring sleeve upper end and sky is enclosed between wood handle and the fixed axis.

Above-mentioned drill chuck is the sleeve of large and small interior shoulder hole.

Place drill chuck below the following inner conical surface of above-mentioned rotaring sleeve endoporus shoulder.

Above-mentioned rope stayed pole is wrapped in the rotaring sleeve outer surface clockwise with its rope.

The endoporus shoulder of above-mentioned rotaring sleeve is radially offered a radial direction through hole.

Offer a radial hole on the above-mentioned locking cap outer wall.

Owing to adopt such scheme: simple in structure, volume is little, cost is low, also without driven by power.

One embodiment further specifies the utility model below in conjunction with accompanying drawing.

Fig. 1 the utility model exemplary embodiments outside drawing.

Fig. 2 the utility model typical case implements generalized section.

Among the figure: 1, wood 2, fixed axis 3, rotaring sleeve 31, shoulder 32, radial direction through hole 4, axially shelves cover 5, ball 6, drill chuck 61, big endoporus 62, little endoporus 7, locking cap 71, radial hole 8, the stayed pole of restricting

As shown in Figure 2, wood has a macropore to 1 bottom, and an aperture is arranged toward in, and wooden materials is made, and is suitable for handing and pushing (genus prior art);

Fixed axis 2 is step axles of a size diameter and is conical end in smaller diameter end; With the corresponding insertion of its large and small diameter shaft wood in 1 the large and small hole and its conical end wedging wood in 1, the minor diameter of this fixed axis 2 with wooden the tight secure fit of 1 aperture, and its major diameter and step thereof and wooden 1 macropore is had the space.

The endoporus middle part of rotaring sleeve 3 has shoulder 31, and these shoulder 31 above and below are that inner conical surface and center have a little centre bore, places a ball 5, the top of withstanding drill chuck 6 on the following inner conical surface on last inner conical surface; The upper and lower end of this rotaring sleeve 3 has external screw thread; In addition, radially offer a radial direction through hole 32, insert stock when supplying to tighten rotaring sleeve 3, increase rotating torque or laborsaving at interior shoulder 31; Simultaneously rotaring sleeve 3 middle part outer surfaces have straight knurling, turn when moment (little) rotaring sleeve 3 usefulness for hand.

Axial shelves cover 4 roofs have the aperture sky and are enclosed within on the minor diameter of fixed axis 2, and between roof and fixed axis 2 shoulders the space is arranged, and its cover endoporus has internal thread and is connected with rotaring sleeve 3 upper external screw threads, be in wood in 1 the macropore and sky be enclosed within wooden 1 and fixed axis 2 between, space (not contacting) is promptly arranged, cooperate and the major diameter axle that makes rotaring sleeve 3 endoporus and fixed axis 2 is movable, these fixed axis 2 major diameter axle bottom faces are supported on the rotaring sleeve 3 on the ball above the inner conical surface 5 again.

Drill chuck 6 be large and small in

shoulder hole

61,3 millimeters of 62(macropore φ, 1.7 millimeters of aperture φ) sleeve, except that drill chuck 6 centre positions, all have 3 or 4 uniform straight joint grooves, the drill bit resilient clamp and the two ends outer surface that make drill chuck 6 two ends can insert large and small different two specifications are the conical surface, and this drill chuck 6 inserts below the rotaring sleeve 3 middle interior shoulders 31.

Locking cap 7 is connected on the rotaring sleeve 3 lower end external screw threads with its internal thread, simultaneously compress drill chuck 6, make it clamp drill bit, offer a radial hole 71 on the outer wall of this locking cap 7 with its lower end inner conical surface, locking cap 7 is tightened in gib head insertion for hook wrench energetically, makes the drill bit firm grip.

The rope that rope stayed pole 8 is fastened two ends on this pull bar is wrapped in rotaring sleeve 3 outer surfaces clockwise, and tractive rotaring sleeve 3 rotates with the pulling pull bar.
