Abstract

A rechargeable electric drill with storage function is provided with a tool box for keeping drill bit or rotary tool head so that the drill bit is kept along with the electric drill, which is not easy to get lost, and allows easier use and carriage. The rechargeable electric drill contains a reversal knob, a switch, a battery pack and an actuating unit in the front and rear shells. The actuating unit consists of a motor and a gearbox secured to the rear cover, the output shaft of the gearbox is connected with the main shaft with a switchover gear and engages the output gear on the chuck shaft via the switchover gear while the tool box with a pusher mechanism is arranged in the front and rear shells of the rear cover, providing users with an electric tool of time-saving, improved work efficiency, and easy keeping and operation.

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 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 wheel, and meshes people's look by transposition gear and output gear on the collet axis and become; And in the forward and backward housing at bonnet place, also be equipped with the band transfer bar mechanism instrument cases.

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

Fig. 2. the A-A view of Fig. 1.

Fig. 3. the B-B view of Fig. 1.

Fig. 4. the C-C view of Fig. 1.

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

Procapsid (19), back casing (18) be symmetry substantially, reinforcement, joint pin, posting etc. are arranged on the inwall, the installing hole of switch (16), commutation button (15), upper end one sidewall and last Lian Yuanshang have slide groove (4), also have the driving hole (23) of instrument cases (6) on back casing (18) upper end face.

Transfer bar mechanism (1) is soft push rod, and an end is connected with control handle (20), and end is connected with magnet steel (2) in addition.

The cross section of instrument cases (6) 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 the locating notch of through-hole groove dislocation and the support of band through hole, a side in centre position also is fixed with spanner (22).

In the middle of the bonnet (5) through hole is arranged, there is installing hole at the edge, lays spring steel ball (21) in the open pore at edge.

Collet axis (11) is for there is through hole the centre, and appearance is the kink nut (12) of setting one's teeth on edge above the straight spline.

Keep away magnetosheath (8) between the through-hole groove of collet axis (11) and instrument cases (6).

Actuating unit is fixed on the bonnet (5) by direct current generator (3) and gear-box (7), motor shaft is connected with gear in the gear-box (7), the output shaft of gear-box (7) links into an integrated entity with the main shaft (13) of band transposition gear (14), and goes up output gear (9) the engagement composition that tape spool holds (10) by transposition gear (14) and collet axis (11).Drill chuck is fixed on the collet axis (11) with screw thread, and is connected locking with the outer buttress screw thread of nut of setting one's teeth on edge (12) and drill chuck.

With the bracket holes kink of instrument cases (6) on the cylindrical of power set, putting into spring steel ball (21) simultaneously locatees in bonnet (5) rim openings hole, put into together in the back casing (18), instrument cases (6) spanners (22) are placed in the driving hole (23), transfer bar mechanism (1) is placed in the slide groove (4) on the back casing (18), (15) are turned round in switch (16) commutation put into back casing (18), cover procapsid (19), screw links into an integrated entity, put into power brick (17) again and form the storable Charge).

Unclamp the drill chuck pin, required drill bit enters in the instrument cases (6) through the through hole in the middle of the collet axis (11) and deposits, and what a is put the spanner (22) on the instrument cases (6) is stirred again, changes an angle.Continue then to put into drill bit, enter in the instrument cases (6) and deposit from the intermediate throughholes of collet axis (11).And the like, can make standby drill bit and use, do not repeat.During use, find out needed that drill bit the driving hole (23) from back casing (18) earlier, stir control handle (20) then, promote drill bit forward by soft push rod, and enter in the drill chuck, make its chucking, at this moment Push switch (16), motor (3) rotates, and drives main shaft (13) and rotates, by the transposition gear (14) on the main shaft (13), make with the output gear (9) of its engagement and rotate, the drill chuck that just drives the collet axis (11) on it and have a drill bit rotates and carries out work, and work finishes, trip switch, motor (3) stops operating, drill chuck stops operating, stir control handle (20) again, soft push rod is withdrawn into original position, because the effect of magnet steel (2), drill bit retracted leave the instrument cases origin-location in, for using next time.And control handle (20) is locked on the forward and backward housing, avoid drill bit from instrument cases (6), to drop out.

The utility model is compared with prior art: can deposit drill bit or rotating tool head because instrument cases are arranged in the housing, begin Drilling tool and electric drill are kept at together at last, can not lose the phenomenon with the look round for drill bit, use, take Band is convenient. Especially be the user of ascend operation, the more easily instrument that uses is provided, loading and unloading, transposing are bored Head is convenient, and the phenomenon of drill bit from falling down in the air can not take place, and has alleviated labour intensity, has saved the time, carries High operating efficiency.
