To the direction in stroke axis to wave (pendulum) action drives process tool 20.Therefore, in a mode of operation, add
Work cutter 20 executes rocking action stroke.
Fig. 2 a and Fig. 2 b and Fig. 3 a and 3b show the detailed side view cutaway drawing of clamping device 30.Clamping device 30 wraps
It includes clamping element 31, keep sleeve 32 and pop-up element 33.
Fig. 5 shows the details of clamping element 31 into Fig. 9.Clamping element 31 is substantially shaped as with first end
311 and the second end 312 conical sleeve.As shown in figure 5, release lever 313 is fixed to the outer surface of clamping element 31.Release lever
313 is prominent from the outer surface of clamping element 31, and for operating clamping device 30 (specifically clamping element 31).Fig. 7,8
Several cross-sectional views of clamping element 31 are shown with 9.The first end of clamping element 31 includes internal screw thread and is used to that dress will to be clamped
30 connections (i.e. spiral connection) is set to holding sleeve 32.The second end of clamping element 31 includes for receiving process tool 20
Connect the reception recess portion 314 of end 201.Therefore, the second end of clamping element 31 is formed as slot.In addition to this, clamping element
31 include the recess portion 315 in inner surface area.Recess portion on the inner surface of clamping element 31 can also be described as cavity,
Pit or groove.As described in more detail la, the recess portion is for partly keeping blocking element 34.
Figure 10 a to Figure 13 shows the details for keeping sleeve 32.Keeping sleeve 32 is with first segment 321 and second segment
The form of 322 stepped (graded) cylindrical body, and the connection end 201 for keeping process tool 20.First
Section includes external screw thread, and is used to be swirled to the internal screw thread of clamping element 31.Fig. 2 a to 3b, which is shown, keeps 32 He of sleeve
Clamping element 31 is swirled to mutual arrangement.Keep sleeve 32 to be located in clamping element 31.The free end of second segment
Portion includes two cavitys 323 being located opposite to each other.When process tool 20 is clamped at 30 inside of clamping device, the two chambers
Body boundary adjacent with process tool 20 (border on).In addition, keeping sleeve 32 includes from inner surface longitudinally convex portion outstanding
324 (referring to Figure 10 b).When pop-up element 33, which is positioned at, keeps 32 inside of sleeve, the lug boss is for being cooperated to pop-up member
In the longitudinal groove 331 of part 33, to keep pop-up element 33 to orient relative to holding sleeve 32.In addition, sleeve 32 is kept to wrap
Containing the casing 325 for partly receiving blocking element 34.
As shown in Figure 14 to 18, pop-up element 33 is substantially shaped as the cylindrical body with circular cross-sectional region.Pop-up
Element 33 is used to pop up process tool 20 from clamping device 30.Popping up element 33 includes to extend along the outer surface of pop-up element 33
Longitudinal groove 331.When pop-up element 33 is positioned in sleeve 32, longitudinal groove is formed as cooperation and keeps sleeve 32
Lug boss.In addition to this, pop-up element 33 also includes flute profile cavity 332.The flute profile cavity is used to receive the connection of process tool
End 201.In addition, pop-up element 33 includes the recess portion 333 being located in exterior surface area, the recess portion is closed for partly receiving
Lock element 34.
As shown in Fig. 2 a to 3b, pop-up element 33, which is positioned at, to be kept in sleeve 32.As previously mentioned, keeping the protrusion of sleeve 32
Portion's cooperation is in the inside of the longitudinal groove of pop-up element 33.Pop-up element 33 holding sleeve 32 on its interior is positioned at folder again
Tight 31 inside (a to Fig. 3 b referring to fig. 2) of element.As previously mentioned, the external screw thread of sleeve 32 is kept to be screwed to the interior of clamping element 31
On screw thread.
Keep sleeve 32 that can rotate and can be rotated relative to pop-up element 33 relative to clamping element 31.
Blocking element 34 is formed as sphere (that is, ball) and is positioned within the inside pipe casing of sleeve 32.Blocking element 34
It is partially positioned in the recess portion of clamping element 31 (referring to Fig. 3 a and 3b) or is partially positioned in the recess portion of pop-up element 33
(a and Fig. 2 b referring to fig. 2).
Clamping device 30 further includes the first spring 35 and second spring 36.First spring 35 be torsionspring form and
It is positioned at clamping element 31 and keeps in the cavity between sleeve 32 (a to Fig. 3 b referring to fig. 2).The torsionspring 35 is used for bullet
Spring force is applied to clamping element 31 and keeps on sleeve 32, so that if clamping element 31 and holding sleeve 32 revolve relative to each other
Turn to need to overcome spring force.Second spring 36 is formed as popping up spring and is positioned at top and the lift lever of pop-up element 33
Between 121 (a to Fig. 3 b referring to fig. 2).The pop-up spring 36 is used to apply spring force to pop-up element 33, and adds to force
Work cutter 20 is detached from clamping device 30.
Clamping device 30 can be reversibly located in lock state and release conditions.When clamping device 30 is in locking shape
When state, process tool (i.e. saw blade) is positioned and keeps and (clamping) inside clamping device 30.It is released when clamping device 30 is in
When putting state, process tool 20 can be inserted clamping device 30 or remove from clamping device 30.
Fig. 2 a and 2b show the clamping device 30 being in the lock state.In lock state, pop-up element 33 is being kept
Upper position is in inside sleeve 32.Pop-up spring 36 is compressed, and blocking element 34 is partially positioned in and keeps sleeve 32
Casing 325 in and be partially positioned in pop-up element 33 recess portion 333 in.The inner surface area of clamping element 31 will be latched
Element 34 is pressed to and is pressed onto the recess portion 333 of pop-up element 33.It should be noted that the recess portion of clamping element 31 not with keep sleeve
32 casing 325 aligns (in line with), and blocking element 34 is positioned partially at the recess portion 333 of pop-up element 33
It is interior.Under the lock state, pop-up element 33 can not move down and be clamped element 31 and push away towards pop-up element 33
Dynamic blocking element 34 is latched.Also it is noted that, in the locked state, clamping element 31 is used to receive process tool 20
The reception recess portion of connection end 201 process tool 20 is latched in clamping device 30.Therefore, process tool 20 cannot be from folder
Tight device 30 removes.In addition, torsionspring 35 is not at compressive state during lock state, so that applying without spring force
To clamping element 31 or keep on sleeve 32.
In order to make clamping device 30 enter release conditions from lock state, the user of clamping device 30 must clamp member
Applied force on part 31, and clamping element 31 is rotated relative to pop-up element 33.It is located in clamping element 31 and pop-up element 33
Between torsionspring 35 by spring force be applied to clamping element 31 and pop-up element 33 on so that user must pass through compression
Torsionspring 35 overcomes spring force.
Fig. 3 a and 3b show the clamping device 30 in release conditions.In release conditions, pop-up element 33 is being kept
Lower position is in sleeve 32.Pop-up spring 36 is released and (unclamps), and blocking element 34 is partially positioned in holding
In the casing of sleeve 32 and it is partially positioned in the recess portion 315 of clamping element 31.The exterior surface area for popping up element 33 is existing
In the recess portion 315 for pressing to and being pressed onto clamping element 31 for blocking element 34.Pop up element 33 recess portion 333 not with keep sleeve
32 casing 325 aligns and blocking element 34 is positioned partially in the recess portion 315 of clamping element 31.In the release conditions
In, it is latched since pop-up element 33 is no longer clamped element 31, pop-up element 33 is pushed by pop-up spring 36 now and can
It moves down.Also it is noted that, in the released state, clamping element 31 for receiving the connection end of process tool
Process tool 20 is not latched in clamping device 30 by 201 reception recess portion.Therefore, process tool 20 can be from clamping device 30
It removes or process tool 20 is inserted into clamping device 30.In addition, torsionspring 35 is in during release conditions
Compressive state and to clamping element 31 and keep 32 applied force of sleeve.User must overcome the spring force of torsionspring 35, with
It is maintained at clamping device 30 in release conditions.
