Description
Technical field
The present invention relates to a kind of portable power tool (power tool) with output shaft, this output shaft has the erection unit that can lock be used to keeping processing apparatus.The key that in particular, the present invention relates to a kind of power tool of the above-mentioned type and be applicable to this power tool, this power tool by key operated erection unit to keep described processing apparatus.
Background technology
The common issue with of such power tool is, on the one hand, is difficult to when not in use storing keys safely, is difficult to when needed on the other hand the immediate access key.This problem particularly relates to those Portable grinder and the drilling machines that need to change very continually respectively grinding abrasive disk and drill bit.
For this problem, previous solution comprises outside appurtenances usually in described power tool or supply line, with carrying key when not using., these accessories in most of examples are inconvenient, because they affect the operation of power tool and/or can not guarantee that key does not get loose and drops to somewhere in safe enough ground, cause can not easily finding key in the time of needs.Another solution is that operating personnel are contained in key in its pocket., when power tool, used by other people and before operating personnel perhaps can forget the transfer key, thereby, because perhaps finding key can cause some troubles, when tool operation, may cause unnecessary delay or interruption like this.
Summary of the invention
An object of the present invention is to provide a kind of portable power tool, it has output shaft, this output shaft has the erection unit for processing apparatus, and portable power tool comprises the device be used to the operation key that carries erection unit, thereby can not hinder the operation of described power tool, and safety and the easy storage mode that obtains key are provided when not using key.
Another object of the present invention is to provide a kind of key, and it is applicable to being carried on safely on described power tool, and easily obtains when needed.
The more purpose of the present invention and advantage will be disclosed in following specification and claim.
The preferred embodiment of the present invention is described in detail as follows in connection with accompanying drawing.
The accompanying drawing explanation

Fig. 3 still shows through the lever of power tool and the longitudinal cross-section that is stored in the key in lever with magnification ratio.
Fig. 4 shows the cross section through lever in Fig. 3 and key.
Fig. 5 shows the stereogram of power tool shown in Figure 1, shows in addition processing apparatus erection unit and the operation key that is in the erection unit of cohesive position.
The specific embodiment
Power tool as shown in the figure comprises air grinder, and this air grinder comprises housing 10, and this housing 10 has the main lever 11 that attaches to its rear end, and the less important lever 12 that is fixed to housing 10 1 sides by the mode of screw rod 15.As shown in Figure 3.Main lever 11 has by the choke valve of bar 13 operations, and for the accessory 14 of Bonding pressure pipeline.Housing 10 comprises the electric rotating machine that is set to output shaft is provided power, on this output shaft, disposes for by form, being the erection unit 16 that the processing apparatus of grinding abrasive disk 17 is fixed to output shaft.Erection unit 16 comprises the hexagon jack section do not shown in figure, with key 20, to be connected, for when changing processing apparatus, tightening or loosening erection unit 16.This power tool also comprises the protection device 22 for grinding abrasive disk 17 is protected.
Key 20 comprises columniform shank part 26, and form is the connecting portion 27 of die nut.This shank part 26 comprises the storage tank (pocket) 28 in order to accommodating this connecting portion 27, and this connecting portion 27 is supported on this shank part 26 pivotally by the one end and via horizontal pin 29, thereby moves between folding position and the moving position that stretches out.In folding position, this connecting portion 27 fully is placed in storage tank 28, and wire spring 31 is set to towards this connecting portion 27 of its extended position bias voltage.Respectively as Fig. 3 and shown in Figure 2.This shank part 26 has handle 32 in its outer end.
Less important lever 12 is tubulose, and has open outer end, and this open outer end is used for the described installation screw rod 15 of access, and can be used in the accommodating key 20 that is in storage or favorite places.By the external diameter that makes described shank part 26, slightly be less than the internal diameter of described less important lever 12, and make described connecting portion 27 be in folding position to be placed in fully in described storage tank 28, thereby realize this point.In addition, less important lever 12 has inner sleeve 33, and this inner sleeve 33 extends with the only about half of length of the length of described less important lever 12, and has shoulder 30, when key 20 occupies its memory location in described less important lever 12, to be connected with described connecting portion 27.Because connecting portion 27 keeps towards its extended position bias voltage always, so it will contact with the inner surface of described less important lever 12 always.This means, described connecting portion 27 easily is connected with the internal end surface of described sleeve 33, thereby forms locked instrument, so that key 20 is remained on to the memory location that it is positioned at described less important lever 12.In the memory location of key 20, the outer end of described shank part 26 and handle 32 will flush with the outer end of described less important lever 12 substantially.Can find out, described connecting portion 27 has two purposes, namely, when key 20 occupies the memory location that it is positioned at less important lever 12 inside, connecting portion 27 is as the locked instrument that is in the key 20 of part extended position, as shown in Figure 3, and at key 20, shift out and will be connected to erection unit 16 from its memory location when tightening or loosening erection unit 16, connecting portion 27 is as the Connection Element that is in complete extended position.As shown in Figure 2 and Figure 5.
Yet described less important lever 12 section within it is formed with respectively two couples of cam face 34a, 35a and 34b, 35b, it is set to impel connecting portion 27 to arrive complete folding position from it, to be positioned at the locking position release key 20 of described less important lever 12 inside.This can be by utilizing handle 32 and obtaining from about 90 degree of complete locking position (as shown in Figure 4) screw key 20, and any one cam face 34,35 inwardly all will impel connecting portion 27 and interrupt the linking between the shoulder 30 of connecting portion 27 and described sleeve 33, thereby discharge key 20 with for operation.Between the outer, radial flange 38 of described sleeve 33 and described shank part 26, be provided with helical spring 37, this helical spring 37 is set to apply axial bias power on key 20, thereby at rotation 90 degree so that, after connecting portion 27 coordinates from itself and the locking of described sleeve 33 and break away from and be connected, be convenient to key 20 from described less important lever 12, moving out.
In Fig. 5, demonstrated the operating position of key 20 when tightening or loosening erection unit 16, thereby processing apparatus 17 has been fixed to the output shaft of described power tool.
The key that can fold 20 of the erection unit 16 by being provided for operating processing apparatus, and make in the memory space in its less important lever that is suitable for being placed in described power tool 12, just can obtain such device, by this device, key 20 is safely stored and can be easily got when needed when not using.The key that this can fold and very compact lever configuration, provide a kind of key storage device, and it can not affect the operation of power tool, and still can easily obtain key when needed.
