These second wheel 20 pivots are in first support 12 of this framework 10, and lay respectively near each bottom tube 16 places, and roller 20 provides the foot rest 100 of present embodiment to be convenient to tow.

Please cooperate Fig. 5, Fig. 6, this telescopic lever 30 includes a holding rod 32, is linked to two extension tubes 34, two fixed covers 36 and two guide pin bushings 38 at holding rod 32 two ends, wherein the external form of holding rod 32 is that working platform 204 directions towards table saw 200 arch upward, that is generally be vertical and be connected with extension tube 34, holding rod 32 is docked with a loam cake 322 by a pedestal 321 to be formed and forms a medium altitude chamber 323 in inside, aforementioned pedestal 321 middle positions have an opening 324 and are communicated with this medium altitude chamber 323, and the medium altitude chamber 323 of this holding rod 32 communicates with this two extension tube 34 again; Each extension tube 34 stretches into corresponding bottom tube 16, and in have two relative hole clipping 341 and one first perforations 342 near free end, as shown in Figure 7; Each fixed cover 36 has two shell fragments 361 and one second perforation 362, fixed cover 36 is sleeved on extension tube 34, and the fixture block 361a of its shell fragment 361 inner faces embeds in the corresponding hole clipping 341, making that fixed cover 36 is unlikely breaks away from or rotates relative to extension tube 34, and its second perforation 362 just aligns with first perforation 342; 38 of this two guide pin bushings are set in respectively this bottom tube 16 and the respectively belled position of this extension tube 34 respectively, have the effect of rest extension tube 34.

This actuation member 40 includes a switch 42, two coupling components 44 and two positioning keys 46, wherein:

This switch 42 is placed in the medium altitude chamber 323 of holding rod 32, include a press button 421, a driven member 422 and two is the bias piece of spring 423, wherein, press button 421 is installed in opening 324 places of holding rod 32, and can not switch between activation point P2 in an activation point P1 shown in Figure 10 and shown in Figure 5 under the situation whether user presses; This driven member 422 is a long strip plate that cooperates holding rod 32 shapes to be bent to form, the pivot pin 43 of driven member 422 by and arranged on left and right sides pass and pivot in holding rod 32 and can be in medium altitude chamber 323 the pivot pendulum, do differentiation with pivot pin 43 present positions, the intermediate section 422a of driven member 422 just and the bottom butt of this press button 421, driven member 422 relative one section ends then have a slotted hole 422b; Repeat after the relevant position appearance as for this two spring 423.

This two coupling component 44 is led pushing block 442 by an elongated connecting rod 441 and respectively and is formed, wherein:

Each connecting rod 441 is placed through in the corresponding extension tube 34, and an end has a pivot hole 441a and constitutes first end of coupling component 44, one bolt 47 combines with a nut 48 after passing this pivot hole 441a and this slotted hole 422b, make connecting rod 441 and driven member 422 articulate, the other end of connecting rod 441 then is a thread section 441b, aforementioned spring 423 is sheathed on the connecting rod 441, as shown in Figure 5, spring 423 1 ends are butted on pedestal 321 inwalls, the other end is butted on a pad 45 and causes its elastic force and act on driven member 422, and then causes this press button 421 to be subjected to the roof pressure of driven member 422 and permanently move toward the not activation point P2 that protrudes in this opening 324;

Please cooperate Fig. 7, Fig. 8 again, lead pushing block 442 have a lateral groove 442a for a nut 49 ccontaining, this nut 49 screws togather with the thread section 441b of connecting rod 441, make that leading pushing block 442 links into an integrated entity with connecting rod 441, and lead second end that pushing block 442 constitutes coupling component 44, lead pushing block 442 and have an oblique guide groove 442b in addition.

Please cooperate Fig. 9, positioning key 46 is to be made of a contained piece 461 and a locating stud 462, restrain piece 461 and have the fin 461a that cooperates with the oblique guide groove 442b that leads pushing block 442, and a screw 461b provides the screw thread body 462a of a portion combination of locating stud 462, locating stud 462 has a head 462b in addition.

The above is foot rest 100 each the thin bilge construction and the relevant position explanation of the utility model one preferred embodiment, narrates it now again and manipulates in the back:

In Fig. 4, Fig. 5, telescopic lever 30 is that the bottom tube 16 of relative framework 10 is the state of pulling out, the head 462b of each locating stud 462 passed second positioning hole 162 of bottom tube 16 and stopped fixing on one and fasten position P3 this moment, the press button 421 of this switch 42 is maintained this not activation point P2 because of pressing, this moment, the user must spur foot rest 100, and the composite roller 20 of closing changes and then can drive table saw 200 easily with the conversion workplace.What another was carried is that the block 182c of the back foot pad 182 of present embodiment has and keeps out fixed cover 36 breaks away from bottom tube 16 to avoid the excessive pull of telescopic lever 30 quilts effectiveness because of projection enters bottom tube 16 inside.

When desiring folding telescopic lever 30, the user only needs this press button 421 of grip pressure to shift one's position to this activation point P1, can see through and promote driven member 422 generation pivot pendulum, and then affect connecting rod 441 and lead pushing block 442 and move towards roller 20 directions, lead the oblique guide groove 442b of pushing block 442 and will produce draw restraining piece 461, cause locating stud 462 not fasten position P4 along radially shrinking back to of bottom tube 16, that is the head 462b of locating stud 462 no longer forms with second positioning hole 162 of bottom tube 16 and fastens, as shown in figure 10, so far the user pushes telescopic lever 30, again after the application of force of removing press button 421, the elastic force of spring 423 will affect connecting rod 441 indirectly and lead pushing block 442 and keep towards the opposite direction that departs from roller 20 and move, first positioning hole 161 until locating stud 462 alignment bottom tubes 16, and its head 462b projection enters till first positioning hole 161, so promptly reach the purpose of folding telescopic lever 30, as shown in figure 11.

The foot rest 100 of present embodiment combines because of sawing 200 with table, and its telescopic lever 30 makes things convenient for the user to drive table saw 200 when being drawn out of and using, on the contrary telescopic lever 30 also space temporarily during by collection.Secondly, the framework 10 of foot rest 100 has the effect that protection table saw 200 each side plate avoid being collided, moreover holding rod 32, can obtain to control use than the labour-saving during driven member 422 of collocation form fit holding rod 32 with the design of arching upward.

The above only is a preferable possible embodiments of the present utility model, uses the equivalent structure variation that the utility model specification and claim are done such as, ought to be included in the claim of the present utility model.
