Description

The storable Charge)

The utility model relates to a kind of rechargeable electric tool, particularly a kind of instrument cases is installed, and has the storable Charge) of storing drill bit or rotating tool head function.

Existing commercially available and use electric drill, its instrument and drill bit are separately to deposit, take care of, and the time spent, have taken electric drill to go for drill bit again, drill bit often takes place lose the phenomenon that can not find, and use, carry all inconvenient.Especially open-air work high above the ground is used more inconvenient.On one's body the operator also need take the drill bit of various different sizes to, when changing drill bit aloft, accidentally, drill bit also will climb down and seek from dropping to the ground in the air, has influenced work, brings many worries to the operator again.

The purpose of this utility model is to provide a kind of storable Charge), can deposit drill bit or rotating tool head in the electric drill, carries, easy to use, has improved operating efficiency.

The utility model be achieved in that the storable Charge) by commutation button, switch, power brick, torque adjusting device are installed in forward and backward housing, the powered rotation device is formed, and described actuating unit is fixed on the bonnet by motor and gear-box, the output shaft of gear-box links into an integrated entity with the main shaft of band transposition gear, and constitutes by the engagement of the output gear on transposition gear and the collet axis; And above motor, tooth case, instrument cases are installed.

Fig. 1, structural representation of the present utility model (taking away fore shell).

The A-A view of Fig. 2, Fig. 1.

The B-B view of Fig. 3, Fig. 1.

The C-C view of Fig. 4, Fig. 1.

Below in conjunction with accompanying drawing embodiment of the present utility model is further described:

Procapsid (24), back casing (23) be symmetry substantially, reinforcement, joint pin, posting etc. are arranged on the inwall, the installing hole that adjusting nut (8), switch (21), commutation button (20), Qianmen (9) are arranged on the outer surface, on (2) one sidewalls of back door slide groove (1) is arranged, also have the driving hole (27) of instrument cases (5) on back casing (23) upper end face.

The cross section of instrument cases (5) is a watt shape, 5 through-hole grooves equidistant, opening are arranged above, be used to lay drill bit or the rotating tool head of 5 φ below 6 * 90 millimeters, lower limb have equidistant and with 5 locating notches of through-hole groove dislocation and the support of band through hole, a side in centre position also is fixed with spanner (26).

In the middle of the bonnet (4) through hole is arranged, there is installing hole at the edge, lays spring steel ball (25) in the open pore at edge.

Collet axis (13) is for there is through hole the centre, and appearance is that kink the nut of setting one's teeth on edge (14) above the straight spline.

Qianmen (9) is housed between the through-hole groove of collet axis (13) and instrument cases (5).

Instrument cases (5) rear end have a back door connection (2).

Actuating unit is fixed on the bonnet (4) by direct current generator (3) and gear-box (6), motor shaft is connected with gear in the gear-box (6), the output shaft of gear-box (6) links into an integrated entity with the main shaft (16) of band transposition gear (17), and goes up output gear (11) the engagement composition that tape spool holds (12) by transposition gear (17) and collet axis (13).Drill chuck is fixed on the collet axis (13) with screw thread, and with the outer locking that is threaded of the nut of setting one's teeth on edge (14) and drill chuck (15).

Centring ring (18) on the annular of uniform through hole is arranged, inner ring is a splined hole.

The torque adjusting device is by being placed with steel ball (7) (1-2 grain) and spring (10) at the breach of regulating sleeve (19) and with gear-box (6) junction, inner face at regulating sleeve (19) is embedded with a steel ball, steel ball is transferred centring ring (18), connects adjusting nut (8) outward again and forms.

The main shaft (16) that the torque adjusting device is installed in actuating unit upward is connected one with it, again with the bracket holes kink of instrument cases (5) on the cylindrical of power set, putting into spring steel ball (25) simultaneously locatees in bonnet (4) rim openings hole, put into together in the back casing (23), instrument cases (5) spanners (26) are placed in the wrench hole (27), switch (21) commutation button (20) is put into back casing (23), cover procapsid (24), link into an integrated entity, put into power brick (22) again and form storable charging power station with screw.

Push back door (2) open, the through hole of required drill bit through the centre enters in the instrument cases (5) to be deposited, and what a is put the wrench (26) on the instrument cases (5) is stirred again, changes an angle.Continue the intermediate throughholes of from the back door (2) then and put into drill bit, enter in the instrument cases (5) and deposit.And the like, can make standby drill bit and use, and shut back door (2), do not repeat.During use, find out that required drill bit the wrench hole (27) from back casing (23) earlier, and promotion spanner (26), send only collet axis (13) rear end drill bit, push Qianmen (9) then aside, and the drill gun front end is downward-sloping, force drill bit to slip in the drill chuck, make its chucking, at this moment press beginning (21), motor (3) rotates, and drives main shaft (16) and rotates, by the transposition gear (17) on the main shaft (16), make output gear (11) rotation with its engagement, the drill chuck (15) that just drives the collet axis (13) on it and have a drill bit rotates and to carry out work, and work finishes, unclamp beginning, motor (3) stops operating, and drill chuck (15) stops operating, unclamp drill chuck, the drill gun front end is upwards mentioned, force drill bit to be slided back and leave the instrument cases origin-location in, for using next time.And shut Qianmen (9).Avoid drill bit from instrument cases (5), to drop out.

But clockwise direction rotates adjusting nut (8) and compresses regulating sleeve (19) and spring (10), and output torque is increased, and then moment diminishes on the contrary.

The utility model is compared with prior art: can deposit drill bit or rotating tool head because the instrument box is arranged in the housing, all the time with drilling tool and Electric drill is kept at together, can not lose the phenomenon with the look round for drill bit, uses, easy to carry. Especially be the work of ascending a height The user of industry provides the more easily instrument that uses, and loading and unloading, transposing drill bit conveniently drill bit can not take place from falling down in the air Phenomenon, alleviated labour intensity, saved the time, improved operating efficiency.
