Driver slot 90 is arranged on driving dish 94 towards on the surface of locking member 66, and this driver slot 90 is spiral shell Spin slot.The helix of helicla flute 90 is gradually increased (D2 > D1) around O point radius and extends.In this enforcement In example, O point is the center of driving dish 94, and certain O point can also be relative to the center deviation of driving dish 94 The heart is arranged.Helicla flute 90 has end wall 1 and an end wall 2 104, and wherein end wall 1 is closer to O Point.The angle change of end wall 1 102 to end wall 2 104 is more than or equal to 360 degree, such as 380 degree, and 400 Degree etc..

See Fig. 2 and Fig. 4, connect link slot 106 He that unit 84 includes being arranged on locking member 66 Connector 108.Visible, connecting unit 84 pivotably can set around axial direction 41 (can axis X 1) Put.Actuator 88 can move in link slot 106, and connector 108 can move in driver slot 90. Here, link slot 106 is arranged on locking member 66 towards on the end face of driving dish 94, this link slot 106 For elliptical slot.Elliptical slot 106 there is sidewall 1 and sidewall 2 112.Connector 108 is same Sample is arranged on the end face of driving dish 94, and its shape is all identical with actuator 88 with mounting means, Do not repeat at this.The width of elliptical slot 106 is equal or slightly larger than the diameter of actuator 88.Accordingly, The width of helicla flute 90 is equal or slightly larger than 108 diameters of connector.So, when actuator 88 is even Moving in access slot 106, connector 108 moves in driver slot 90 so that driver element 82 around While axial direction 41 rotation, translation is supported by.In the present embodiment, driver element 82 is vertically Translation in the plane of axial direction 41.It is to say, when operating element 80 drives driver element 82 Relative in the motor process connecting unit 84, driver element moves around driving axis X2, driving axis X2 is parallel to axis X 1, and in motor process, driving axis X2 and the distance variable of axis X 1.

Operating element 80 is an operation handle, and its end-to-end distance off-axis line X1 has certain distance, in order to easily Ground by operating element 80 drive driver element 82 around axial direction 41 rotating while linearly with Connect unit 92 to coordinate.

It is discussed in detail how operating assembly 42 is cut between disengaged mode and matching model below in conjunction with the accompanying drawings Change.

Refer to Fig. 5, Fig. 6 and Fig. 7, operating assembly 42 is moved to matching model by disengaged mode.As Shown in Fig. 5, in disengaged mode, connector 108 is located substantially at helicla flute 90 centre position, with end wall one 102 do not contact with end wall 2 104；Meanwhile, during actuator 88 is also located substantially at elliptical slot 106 Between position.Now, operating element 80 can relative on both direction E, F turn with clamping unit 38 Dynamic.That is, the activity of operating element 80 cannot drive locking member 66 to rotate around axis X 1, thus not Can be swung by clamping unit 38 and be affected.

And if, under the disengaged mode shown in Fig. 5, F drives operating element 80 in a second direction.As Shown in Fig. 6, operating element 80, while driving actuator 88 to move in link slot 106, also carries Dynamic driver slot 90 moves relative to connector 108, and then makes end wall 1 coordinate with connector 108, Actuator 88 also closely cooperates with sidewall 1.At this moment, operating assembly 42 is just moved by disengaged mode To matching model.It is to say, operating assembly 42 is connected without relative rotation with clamping unit 38, Under this pattern, driver element 82 and connection unit 84 and operating element 80 are relatively fixed, along second party Continuing to drive operating element 80 to F, so, operating element 80 is rotating counterclockwise around axis X 1 The most also drive locking member 66 to rotate around axis X 1, thus unclamp work 36.

Or, under the disengaged mode shown in Fig. 5, E drives operating element 80 in the first direction.Such as figure Shown in 7, operating element 80, while driving actuator 88 to move in link slot 106, also drives Driver slot 90 moves relative to connector 108, and then makes end wall 2 104 coordinate with connector 108, drives Moving part 88 also closely cooperates with sidewall 2 112.At this moment, operating element 42 also by disengaged mode move to Matching model.It is to say, operating assembly 42 is connected without relative rotation with clamping unit 38, at this Under pattern, driver element 82 and connection unit 84 and operating element 80 are relatively fixed, in the first direction E continues to drive operating element 80, and so, operating element 80 is same rotate clockwise around axis X 1 Time also drive locking member 66 to rotate around axis X 1, thus lock work 36.

As it is shown in fig. 7, operating assembly 42 is in matching model, drive operating element 80 can drive locking Part 66 rotates clockwise, and locks work 36.And in order to avoid operating assembly 42 operationally by locking Part 66 drives synchronous hunting.Therefore need by matching model, operating assembly 42 is moved to disengaged mode.Cause This is under this matching model, can drive shown in operating element 80 to Fig. 8 by F in a second direction, operation unit Part 80, while F moves in a second direction, promotes end wall 2 104 to disengage with connector 108. At this moment, operating assembly 42 is moved to disengaged mode by matching model.It is to say, operating assembly 42 can To rotate relative to clamping unit 38, in this mode, operating element 80 drive driver element 82 around The translation while that axial direction 41 being rotating.So, then can freely drive operating element 80 move to Correct position, also will not drive locking member 66 to rotate.

The most as shown in Figure 8, continue F in a second direction and drive operating element 80, promote end wall 1 Coordinate with connector 108, operating assembly 42 can be made again to be moved to matching model by disengaged mode.Visible Drive operating element 80 in one direction, operating assembly 42 can be made to be moved to disengaged mode by matching model Move to matching model again.But in real process, it is common that, as work head need to be locked, then by along One direction E operates operating element 80, makes operating assembly 42 be moved to matching model, behaviour by disengaged mode Make element 80 and can drive locking member locking work head.And after locking, then F drives behaviour in a second direction Making element 80, make operating assembly 42 be moved to disengaged mode by matching model, only operating element 80 moves To correct position and fixed, without driving locking member to move together.And if now Multi Role Aircraft 30 Work, locking member also will not drive operating element 80 to swing when swinging.And when unclamping work head, then edge Second direction F drives operating element, makes operating assembly 42 be moved to matching model, behaviour by disengaged mode Making element 80 can drive locking member to unclamp work head.

Refer again to Fig. 1, be fitted in upper cover body 72 at operating element 80, and be provided with Magnet 114.Upper cover body 72 are provided with the Magnet (not shown) attracting with Magnet 114.So, work 36 is installed to defeated After on shaft 34, drive operating element 80 to be at disengaged mode, freely drive operating element 80, When Magnet 114 and Magnet are attracting, operating element 80 is then moved to correct position.So, multi-functional In machine work process, operating element 80 just can be fixed by housing 32 relatively, does not also interfere with operator's Sight line, it is to avoid dangerous generation.Certainly, operating element 80 is relative to the fixing mode of housing 32 not Being only limitted to aforesaid way, those skilled in the art it is readily conceivable that other realization rate, as at housing 32 On buckle be set coordinate with operating element 80, as long as Multi Role Aircraft 30 can be made to work, it is to avoid operation The relative housing 32 of element 80 is movable.

It may be noted that in present embodiment, by driver slot is set to helicla flute, link slot is set to Elliptical slot；And actuator and connector are disposed as cylindrical pin, realize driver element around Being supported by of translation while that axial direction 41 being rotating, i.e. realizes operating assembly at matching model and de- Switch between on-mode.Helicla flute includes end wall one and end wall two, and link slot includes sidewall one and sidewall two, Wherein connector coordinates with end wall one or end wall two, simultaneously drives part and coordinates with sidewall one or sidewall one, behaviour It is in matching model as assembly；Connector and end wall one and end wall two all disengage and state operating assembly and be in Disengaged mode.But the present invention is not limited to aforesaid way, those skilled in the art it is readily conceivable that other Realization rate, switch between matching model and disengaged mode as long as being capable of operating assembly.

Such as, the helicla flute on driver slot exchanges mutually with the elliptical slot of link slot.Again or elliptical slot The change of shape, as being straight trough, or end wall is not semicircle, again or sidewall one and sidewall Two at least a part of which sides arrange the shape with connector mating shapes.Again or driver slot and link slot equal For helicla flute, and spiral fluted helix can also be to be different from this enforcement to be gradually increased around O point radius Extend, and be only to increase around O point radius to extend.And if both of which is helicla flute, then actuator or Connector coordinates with two spiral fluted end walls respectively, then operating assembly is in matching model.The most also Can not only limit to is helicla flute, and only need to be capable of operation can while rotating around axial direction 41 With translation.Driver element 82 is more than or equal to 360 degree relative to the rotational angle of clamping unit 40, Make operating element 80 anglec of rotation in the circumferential more than or equal to 360 degree, so can conveniently operate Element 80 can return back to correct position.Certainly, operating element 80 anglec of rotation in the circumferential also may be used With less than 360 degree.

Specific operation process is discussed in detail below in conjunction with the accompanying drawings.

Shown in Fig. 1, first work 36 is arranged on ring flange 58 and the locking piece 68 of output shaft 34 Between, if the opening (not shown) on the installation portion 60 of work 36 is for close, needing will lock Tight part 66 completely disengages from out with locking piece 68, it to be taken off from output shaft 34, then by locking piece 68 install to output shaft 34 after the opening of work 36.It may be noted that such as work head herein Opening is processed into nonocclusive, leaves the breach in the bar portion that may pass through locking piece.This kind of situation will be without locking Locking member is pulled down completely from locking member, only need to unscrew locking member, make locking piece and output shaft carrier it Between reserve and be available for the gap that the installation portion of work head passes.

After locking piece 68 is inserted the cavity 56 of output shaft 34, the top external screw thread in its bar portion 78 and lock The screwed hole 77 of tight part 66 contacts.At this moment, overcome the elastic force of elastic component 98, the most somewhat pull behaviour Make element 80, be further continued for driving operating element 80 so that operating assembly 42 is moved to joining by disengaged mode Syntype.Seeing Fig. 7, E drives operating element 80 in the first direction, drives actuator 88 connecting While groove 106 moves, also drive driver slot 90 to move relative to connector 108, and then make end wall 2 104 coordinate with connector 108, and actuator 88 also closely cooperates with sidewall 2 112.Operating element 42 are also moved to matching model by disengaged mode.In this mode, driver element 82 and connection unit 84 And operating element 80 is relatively fixed, E continues to drive operating element 80 in the first direction, and then passes through Driver element 82 drives locking member 66 around the relative locking piece of axis X 1 68 with the cooperation connecting unit 84 Rotate.Owing to the screwed hole 77 of locking member 66 and the bar portion of locking piece 68 are threaded engagement, revolve at screw thread Under the effect of clamp force, locking piece 68 while rotating axially on move, eliminate work 36 and locking piece Axial gap between 68 and the ring flange 58 of output shaft 34.As it is shown in figure 9, continue rotation process unit Part 80, until feel that operating element 80 rotates difficulty, now works 36, locking piece 68 and defeated Ring flange 58 three of shaft 34 is respectively provided with the biggest axial normal pressure each other, has accordingly The biggest frictional force, thus enough moments of torsion can be transmitted to prevent work head and locking piece 68 and output Occur between the ring flange 58 of axle 34 relatively sliding, and affect work efficiency.

After locking member 66 and locking piece 68 are locked completely, then may refer to Fig. 8.Operating assembly 80 quilt F drives in a second direction, promotes end wall 2 104 to disengage with connector 108.At this moment, operational group Part 42 is moved to disengaged mode by matching model.In this mode, operating element 80 drives driver element 82 around axial direction 41 rotating while translation.So, then operating element 80 can be driven to move Move the correct position absorbed mutually with the Magnet of setting in upper cover body 72 to Magnet 114, and then prevent locking member 66 drive operating assembly 42 to swing together.

By introduction to the operating procedure of installment work 36 above, it is readily appreciated that dismantlement work head Contrary operation is performed when 36.When needing dismantlement work 36, only need to drive operation unit counterclockwise Part 80, makes operating assembly 42 be moved to matching model by disengaged mode.

Specifically can be found in Fig. 6, F drives operating element 80 in a second direction, drives actuator 88 even While moving in access slot 106, connector 108 moves also relative to driver slot 90, and then makes end wall one 102 coordinate with connector 108, and actuator 88 also closely cooperates with sidewall 1.At this moment, operational group Part 42 is the most just moved to matching model by disengaged mode.In this mode, driver element 82 and connection are single Unit 84 and operating element 80 are relatively fixed, and drive operating element 80 counterclockwise, by driver element 82 Drive locking member 66 to rotate relative to locking piece 68 around axis X 1 and unclamp threaded, make locking Part 68 axially moves down certain distance；Finally, operating element 80 continues to rotate, until locking member 66 and lock Locking member 68 is completely disengaged threaded, now can be pulled down from output shaft 34 by locking piece 68, takes out work Work 36.

By described above, the Multi Role Aircraft 30 of the present invention is arranged on the operation on housing 32 by employing Assembly 42, in the case of not using other aid, only need to be in both direction clockwise or counterclockwise Drive operating assembly 42, can turn in the two directions relative to locking piece 68 by fast driving locking member 66 Dynamic, it is achieved the Fast Installation of work 36 or dismounting.Operation interface person the simplest, easily operated grasp. Add and rotate some circles drive locking member 66 and locking piece 68 screw fastening by operation operating assembly 42 Tightly, therefore, it is possible to ensure that the axial normal pressure that work 36 is subject to is sufficiently large, work 36 is made stably may be used It is installed on output shaft 34 by ground, prevents work 36 from occurring skidding under any working environment, carry The work efficiency of high workload 36.

It addition, operating assembly 42 is by arranging driver element 82 further and connecting unit 84, make behaviour Make assembly to switch between matching model and disengaged mode.After work 36 is locked, drive behaviour Make assembly 42 to be moved to disengaged mode by matching model, it is to avoid locking member 66 drives operating assembly 42 to move, Thus decrease the friction between operating assembly 42 and locking member 66 and vibrations, make whole instrument have more Good operating handle.And, operating element 80 is arranged at output shaft 34 one end away from ring flange 58, Hence away from work 36, work 36 will not be touched during operation operating element 80, thus prevent by mistake Hurt operator.

In above-mentioned embodiment, the angle that the operating assembly 42 of Multi Role Aircraft 30 rotates under matching model Scope is more than 90 degree, and preferred rotation angle range is more than or equal to 360 degree, less than or equal to 1080 Degree.It may be noted that the hand-held tool of the present invention is to drive locking member relative to locking piece by operating assembly Rotate against, and eventually through screw-threaded coupling.It should be understood readily by those skilled in this art, operating assembly can To rotate some circles, until locking member is locked with locking piece.

Wherein operating element 280 is with the operating element 80 in the first embodiment.With in the first embodiment Multi Role Aircraft 30 is compared, and driver element 282 and connection unit 284 have different structures.

As shown in figure 11, driver element 282 includes arranging the main body including being connected with operating element 280 286, the actuator 288 being arranged in main body 286.Wherein main body 286 includes superposed vertical circle Column connecting portion 292 and the discoid driving dish 294 being positioned at bottom.Wherein, connecting portion 292 and behaviour The connected mode making element 280 is same as the first embodiment, does not repeats at this.With the first embodiment Except that, operating element 280 can drive driving dish 294 to rotate around axis X 3.Actuator 288 Be arranged on the medial surface of driving dish 294, including the upper side 2881 be arrangeding in parallel and downside 2882, The first drive surface 2883 be arrangeding in parallel and the second drive surface 2884, the first cooperation face 2885 be arrangeding in parallel Face 2886 is coordinated with second.Wherein upper side the 2881, first drive surface 2883, first coordinate face 2885, Downside the 2882, first drive surface 2884 and the first cooperation face 2886 are sequentially connected with.And first drive surface 2883 are obliquely installed relative to upper side 2881；First cooperation face 2885 is perpendicular to upper side 2881 He Downside 2882.

As shown in figure 12, connect unit 284 and include the first connector 208 and the second connector 210, excellent Choosing, the first connector 208 and the second connector 210 stagger setting at axial direction 41.Here mistake Offer to put and refer to and horizontal direction both direction upper at axial direction 41 (longitudinal direction) and all stagger setting.

First connector 208 and the second connector 210 are outside axial direction 41 is arranged on locking member 266 On side.Concrete, the first connector 208 include the upper end face 2081 that be arranged in parallel and lower end face 2082, First abutment face 2083 and second abutment face the 2084, first slide surface 2085 of angled setting.Accordingly The second connector 210 also include the upper surface 2101 be arrangeding in parallel and lower surface 2102, angled set The first bearing surface 2103 and second bearing surface the 2104, second slide surface 2105 put.Wherein first connects The upper end face 2081 of part 208 be arranged in parallel with the lower surface 2102 of the second connector 210.Angled set First bearing surface 2103 of the first abutment face 2083 of putting and the second abutment face 2084 and angled setting With the second bearing surface 2104 towards setting.

Actuator 288 may select and coordinates in the first connector 208 or the second connector 210, i.e. actuator 28 select coordinate arbitrary with the first connector 208 and the second connector 210, and operating assembly 242 is in Matching model, operating assembly 242 is connected without relative rotation with clamping unit 238, then can drive Locking member 266 rotates.And actuator 288 disengages and joins with the first connector 208 or the second connector 210 Closing, i.e. actuator 288 is not arbitrary with the first connector 208 and the second connector 210 coordinates, then grasp Making assembly 242 and be in disengaged mode, operating assembly 242 then can relatively rotate with clamping unit 238, Affected from without being swung by clamping unit 238.

Concrete, referring to Figure 13 a to Figure 13 d, operating assembly 242 is with disengaged mode moves to Pattern.As depicted in fig. 13 a, in disengaged mode, actuator 288 and the first connector 208 and second connect Arbitrary in fitting 210 all mismatching, now, operating element 280 and clamping unit 238 can be at two Relatively rotate on direction.That is, the activity of operating element 280 cannot drive locking member 266 around axis X 3 Rotate, affected from without being swung by clamping unit 238.

And if, under the disengaged mode shown in Figure 13 a, E rotating operation element 280 in the first direction Mobile to Figure 13 b；Continue in the first direction during E rotating operation element 280, such as Figure 13 c institute Showing, the first drive surface 2883 of actuator 288 connects with the second slide surface 2105 of the second connector 210 Touch and slide along the second slide surface 2105.Now, actuator 288 is rotating around axial direction 41 The most in axial direction translation on 41.Continue E rotating operation element 280 in the first direction, until driving First drive surface 2883 of moving part 288 contacts with the second abutment face 2084 of the first connector 208；Drive First cooperation face 2885 of moving part 288 contacts with the first abutment face 2083 of the first connector 208.Can Seeing Figure 13 d and Figure 14, at this moment, actuator 288 coordinates with the first connector 208, operating assembly 242 Mobile to matching model.It is to say, operating assembly 242 connects without relative rotation with clamping unit 238 Connecing, in this mode, driver element 282 and connection unit 284 and operating element 280 are relatively fixed, E is rotated further operating element 280 in the first direction, and locking member 266 can be driven around axis X 3 turns Dynamic, thus lock work 236.

And during screwing, due to the first abutment face 2083 with the second abutment face 2084 is angled sets Put, so face 2885 and the first drive surface 2883 can be coordinated with first respectively to be in close contact, it is simple to behaviour Making element 280 drives locking member 266 to rotate around axis X 3.And it is sliding for preventing on axial direction 41 Dynamic, referring back to Figure 13 d, the upper side 2881 of actuator 288 is by the bottom surface 2102 of the second connector 210 Stop.And the included angle A between the first abutment face 2083 and the second abutment face 2084 and the first drive surface 2883 and first coordinate the included angle B between face 2885 identical, can be obtuse angle can also be acute angle.When So, if angle difference can also, if included angle A is more than included angle B, if the first abutment face 2083 He Second abutment face 2084 can stop the first cooperation face 2885 and the first drive surface 2883.

And during unscrewing, due to the first bearing surface 2103 with the second bearing surface 2104 is angled sets Put, so face 2886 can be coordinated to be in close contact with the second drive surface 2884 and second respectively, it is simple to behaviour Making element 280 drives locking member 266 to rotate around axis X 1.And it is sliding for preventing on axial direction 41 Dynamic, the downside 2882 of the first bearing surface actuator 288 is by the upper end face 2081 of the first connector 208 Stop.

And the angle C between the first bearing surface 2103 and the second bearing surface 2104 and the second drive surface 2884 With second coordinate the angle D between face 2886 identical, can be obtuse angle can also be acute angle.Certainly, If angle difference can also, if angle C is more than angle D, if the first bearing surface 2103 and second Bearing surface 2104 can stop the second drive surface 2884 and the second cooperation face 2886.

Certainly, face is coordinated to coordinate if only arranging the first bearing surface with second on actuator, it is also possible to reach To matching model, and locking member 266 is driven to rotate around axis X 3 by operating element 280.And First bearing surface can also be parallel to axial direction 41 and extend, or tilts necessarily relative to axial direction 41 Angle.

Included angle A between first abutment face 2083 and the second abutment face 2084 and the first bearing surface 2103 And the angle C that second between bearing surface 2104 can also angle identical.

It may be noted that in present embodiment, selectable with the first connector with the by arranging actuator Whether two connectors coordinate, realize driver element around axial direction 41 rotating while along axis Being supported by of direction translational, i.e. realizes operating assembly and switches between matching model and disengaged mode.Drive Moving part selectively coordinates with the first or second connector, and operating assembly is in matching model；Actuator with First and second connectors all disengage, and operating assembly is in disengaged mode.But the present invention does not limit In aforesaid way, those skilled in the art it is readily conceivable that other realization rate, as long as being capable of behaviour Make assembly to switch between matching model and disengaged mode.

Such as, actuator and the first connector or the second connector are not contacted with face by face and drive its turn Dynamic, such as latch, steel ball etc. can be set.

And for example driver element includes staggering two actuators arranged along described axial direction, and connects unit Including a connector, select coordinate and mismatch with two actuators by connector, realize behaviour Make assembly to switch between matching model and disengaged mode.Connector and two one of them cooperations of actuator, Operating assembly is in matching model；Actuator and two actuators all disengage, then operating assembly is in Disengaged mode.

First abutment face 2083 and the second abutment face 2084 and the first of angled setting of angled setting Bearing surface 2103 and the second bearing surface 2104 are towards setting.Can make operating element 280 in the circumferential The anglec of rotation, more than 360 degree, so can facilitate operating element 80 can return back to correct position.Certainly, Also can be by the first bearing surface 2103 of the first abutment face 2083 and the second abutment face 2084 with angled setting Arrange dorsad with the second bearing surface 2104, or by the first connector and the second connector position in the axial direction In same straight line, equally realize creating conception of the present invention.

And, those skilled in the art, it is readily conceivable that translation while rotating around axial 41, go back It can be simultaneously both direction translation in the axial direction with in the plane being perpendicular to axis direction.

By described above, the Multi Role Aircraft 230 of the present invention is arranged on the behaviour on housing 232 by employing Make assembly 242, in the case of not using other aid, only need to around axial direction 41 two not Same side drives up operating assembly 42, can exist relative to locking piece 268 by fast driving locking member 266 Rotate in both direction, it is achieved the Fast Installation of work 236 or dismounting.Operation interface is very simple, Easily operated person grasps.
