The specific embodiment

To shown in Figure 6, a kind of vapour-pressure type saw blade location lock 10 that the utility model first preferred embodiment is provided mainly is made up of a basal disc 11, plural fixed bar 15, a shrouding disc 21, a piston plate 25 and a locking disk 31 as Fig. 1, wherein:

This basal disc 11, middle recessed and plurality of through holes 12 is set in the periphery isogonism, and these basal disc 11 outer rims are provided with a recess 13 corresponding to the position of respectively this perforation 12.

Plural number fixed bar 15, the top has a top board 16, end section forms a minor diameter part 17 in side face, and has a large-diameter portion 18 in lowermost end, this fixed bar 15 is to pass these perforation 12, and be provided with an elastic component 19 between this top board 16 and this substrate, this elastic component 19 is to be the folded mutually shell fragment of plural number in present embodiment.

This shrouding disc 21, intermediate recess and covering place on this

basal disc

11, and and 11 of this basal discs form a space, these shrouding disc 21 central authorities have a valve 22, this shrouding disc 21 is to be locked on this basal disc 11 by some screws 23.

This piston plate 25, plug is located in this shrouding disc 21, and on every side and be provided with oil sealing 26, this piston plate 25 can be driven and in these shrouding disc 21 intrinsic displacement preset distances, these piston plate 25 cards are the top boards 16 that are butted on these fixed bars 15.

This locking disk 31, its card is provided with plural fixing hole 32 corresponding to these fixed bars 15, respectively this fixing hole 32 is that to be arcuation microscler, its aperture is gradually little by a side direction opposite side, can cooperate this fixed bar 15 respectively to insert,, make this fixing hole 32 respectively be embedded in the respectively minor diameter part 17 of this fixed bar 15 with the part of its smaller aperture due again by this locking disk 31 of rotation by the part of larger aperture, reaching fixing effect, the periphery of this locking disk 31 has plural recess 33 corresponding to this fixing hole 32 respectively.

Present embodiment can cooperate a saw blade 41, and this saw blade 41 has some trepannings 42, and can be placed in these fixed bars 15 and between this basal disc 11 and this locking disk 31.

To shown in Figure 6, the utility model is to see through the gas injection in this shrouding disc 21 of this valve 22 earlier when installing saw blade 41 as Fig. 5, and therefore this piston plate 25 promptly shifts to this basal disc 11, and oppressing these fixed bars 15 simultaneously stretches out, and then this locking disk 31 is moved apart this basal disc 11; Again saw blade 41 is placed in these fixed bars 15 by these trepannings 42, fashionable at cover, can be by set recess 13 auxiliary alignings of these basal disc 11 outer rims; At last this locking disk 31 is placed in these fixed bars 15 by the part of the larger aperture of these fixing holes 32, rotating this locking disk 31 makes this fixing hole 32 respectively be embedded in the respectively minor diameter part 17 of this fixed bar 15 with the part of its smaller aperture due, to be fixed on these fixed bars 15, in rotation, can be aligned with the recess 13 of these basal disc 11 peripheries by the recess 33 of these locking disk 31 peripheries, the user can only can judge whether locking by outward appearance, and then can guarantee the lock-out state of saw blade 41.

Then, extremely shown in Figure 8 as Fig. 7, by air-breathing to this valve 22, force this piston plate 25 to move to this shrouding disc 21, these elastic components 19 promptly act on these fixed bars 15 and make in it and contract, these fixed bars 15 are promptly shifted to this basal disc 11 by its large-diameter portion 18 till touching with this locking disk 31, this saw blade 41 can be sandwiched between this locking disk 31 and this basal disc 11 thus, and can reach the effect that locks saw blade 41.

When desiring to unload saw blade 41, only need inverted sequence aforementioned operation mode to get final product.

What must be replenished a bit is, in the present embodiment, respectively this elastic component 19 also can be a spring, and have with on take off the identical effect of shell fragment.

As from the foregoing, the utility model has the advantage of:

One, locking is stable: by design of the present utility model, can be after fixing saw blade, and profit again Provide the strength of clamping saw blade with these elastic components, make the stable strength that is fixed of saw blade Clamping can make the locking condition of saw blade stable thus, and saw blade can not come off and drop out.

Two, install fast: by design of the present utility model, making things convenient for the user to be reached by this basal disc should Whether the recess of locking disk outer rim is aimed at, can only be found out to lock by outward appearance and finish, can be fast and Finish easily the action of installation.
