Description
Technical field
The present invention relates to a kind of with drum-type tool magazine, and rotatable tool storehouse is to change the hand-held electricity of cutter
Power driven tools.
Background technology
The Chinese patent application of Publication No. CN101563192 discloses a kind of electricity with drum-type tool magazine
Power driven tools.This electric tool has pistol-shaped casing, and has the upwardly extending main shaft in gun barrel side, electricity
Power driven tools output shaft, in the exit in gun barrel direction, is a cutter dop, and casing is built with motor, drum-type cutter
Tool storehouse and actuating device, drum-type tool magazine is cylindrical structure, the axis of drum-type tool magazine and cutter card
The axis of head is parallel to main shaft, and drum-type tool magazine annular with oneself is provided with the cutter parallel with main shaft
Room, these cutter rooms occupy the overlapping bit aligned with cutter dop respectively according to the position of rotation of drum-type tool magazine
Putting, in this lap position, corresponding cutter can shift between cutter room and cutter dop, described transfer
Coaxial with cutter dop by being in, the actuator operating saddle form guided in hull outside is real
Existing.Drum-type tool magazine is formed on housing equally, and the center that drum-type tool magazine is surrounded by cutter room
Being run through by the power transmission shaft of actuating device in territory, rotary shaft drives with cutter dop through this tool magazine and by gear
Formula connects, and can rotate by band cutter dop.
If using the cutter in the electric tool tool magazine to be changed of this structure, then need whole cutter
Storehouse removes, and thus needs to tear open whole casing, very inconvenient.
Summary of the invention
The technical problem to be solved is, overcomes the defect of prior art, it is provided that one more tool changing
Cutter electric tool simply and easily in tool storehouse.
For solving above-mentioned technical problem, the present invention proposes a kind of electric tool, and it includes casing, motor, transmission
Device, cutter dop and drum-type tool magazine, the cutter room in described drum-type tool magazine can be adjusted to every time
Cutter in cutter room can be transferred on the position of cutter dop by one, and the power transmission shaft of described actuating device is located at
The outside of drum-type tool magazine, described drum-type tool magazine is rotationally connected with casing.
Described actuating device and motor drive connection, actuating device include change speed gear box, the first gear train, power transmission shaft,
Second gear train, the output shaft of motor is connected with change speed gear box, and the output shaft of change speed gear box is connected by the first gear train
Power transmission shaft, described power transmission shaft is located at the outside of drum-type tool magazine, and the other end of described power transmission shaft passes through the second tooth
Wheels are connected with cutter dop, rotate for band cutter dop.When starting electric tool, driven by motor passes
The output shaft rotation of dynamic device, and by power transmission shaft and the first gear train and the second gear set drive cutter dop
Rotate, complete the action of electric tool.
Described drum-type tool magazine includes the roller coaxial with drum-type tool magazine and for installing the rolling of roller
Wheel support, is provided with support seat in described casing, described rolling wheel support is rotatably connected in support seat, rotary motion trace
Place plane is perpendicular to the axis of roller.
Being additionally provided with on described support seat to rotate for rolling wheel support and guide and spacing arcuate groove, described roller props up
Frame is provided with the end that coordinates with arcuate groove the first spring with the first ball, when rolling wheel support rotates, first
Ball slides in arcuate groove, and the two ends of described arcuate groove are equipped with for spacing locating slot, described locating slot
Depth and width be all higher than arcuate groove.Using this structure, when rolling wheel support rotates, pair roller support is carried out
Guiding and spacing, the first ball is when sliding into the position of locating slot at arcuate groove two ends, due to locating slot
Depth and width are all higher than arcuate groove, and due to the elasticity of the first spring, the first ball is just stuck in locating slot,
Thus rotational angle and the stroke of pair roller support limits, and during position between arcuate groove two ends,
Owing to there being the guide effect of arcuate groove, rotation roller support of the most somewhat exerting oneself, rolling wheel support will be at arcuate groove
In the range of rotate.Arcuate groove head and the tail two ends are carried out spacing, is when rolling wheel support is screwed out, prevents firmly
Excessive and damage rolling wheel support, and when recovery roller support, play the effect of location.
Being provided with cutter room in the roller of described drum-type tool magazine, the center of described roller is provided with axial axis hole,
Described rolling wheel support is provided with axle and is connected with roller through axis hole, and described axle is provided with and is perpendicular to the of axis direction
Two springs, the two ends of described second spring are respectively connected with the second ball, and the circumference of described axis hole is provided with and cutter
The draw-in groove that the quantity of room is corresponding, described second ball and card slot fit.The bottom surface of described draw-in groove is cambered surface, uses
In accommodating second ball.On rolling wheel support during rotation roller, draw-in groove and the cooperation of the second ball can be passed through, make
Rotate the angle that equal transmission is fixing every time so that the cutter in the tool magazine of each turned position all with cutter dop
Positive corresponding, do not have deviation, make cutter discrepancy tool magazine the most smooth and easy.
After using said structure, the invention have the advantages that the power transmission shaft of actuating device is located at rolling by the present invention
The outside of cartridge type tool magazine, and not through drum-type tool magazine, but also drum-type tool magazine can be rotated
It is connected in casing, so need not take casing apart and just drum-type tool magazine can be screwed out, in order to change cutter
Cutter in storehouse, screws in casing after replacing again and the most directly can use, simple and convenient, makes this electric tool
The kind of portability cutter increases significantly, such as various screwdriver bits, drill bit etc., greatly extends this electronic work
The range of tool.
