The specific embodiment

See also Fig. 2 to Fig. 5, the utility model provides a kind of breast bench to adjust the preferred embodiment of the locked instrument of runner, be to be pivoted with lifting and the angle of inclination that two rotating shafts 30 can be controlled saw carriage 21 in this breast bench 20 relatively on this breast bench 20, and these rotating shafts 30 are terminal and be pivoted with two runners 40 in the outside of this breast bench 20 and can conveniently rotate, wherein:

This rotating shaft 30, its end is to convex with a pivot cover portion 31, in this pivot cover portion 31 and cut and be provided with a confined planes 311, simultaneously, the end of this pivot cover portion 31 is provided with a spiro union portion 32 in addition, and it is the end that is convexly set in this pivot cover portion 31 for a screw rod, in addition, be with a packing sleeve 33 in this rotating shaft 30 and in the outside of this breast bench 20 pivot, the end of this packing sleeve 33 is slightly protruding in this pivot cover portion 31;

These runner 40 central authorities are equipped with a coupling hole 41, this coupling hole 41 is that cover is fixed in the pivot cover portion 31 of this rotating shaft 30, and be provided with a limiting section 411 on this coupling hole 41 and with respect to this confined planes 311, these runner 40 pivots are limited in this rotating shaft 30, and these runner 40 rotatable these rotating shafts 30 are rotated, simultaneously, the ring week of this runner 40 go up and convex with a throw rod 42 and can conveniently rotate this runner 40, in addition, the outside of this runner 40 also is bolted with a fixing button 43 with respect to this spiro union portion 32, these fixing button 43 central authorities are provided with a screw 431 with respect to spiral shell on this spiro union portion 32, and can on this spiro union portion 32, have an axial spiral shell to advance, simultaneously, the outer rim of this fixing button 43 is that rotate with convenient the rotation section 432 that convexes with predetermined number.

By for further understanding the effect that the utility model structural feature, application technology means and institute's expection are reached, now the utility model occupation mode is narrated, believing be able to have more deep and concrete understanding to the utility model therefrom, as described below:

See also shown in Figure 6, breast bench of the present utility model 20 needs when the lifting of saw carriage 21 and angle of inclination are controlled in this rotating shaft 30, need first this fixing button 43 of spiral shell pine, make this runner 40 free to rotate, and drive lifting and the angle of inclination that saw carriage 21 is controlled in this rotating shaft 30; Please cooperate consult shown in Figure 5, after the position adjustment of breast bench 20 saw carriages 21 is finished, screw tight this fixing button 43, this fixing button 43 is moved toward these runner 40 directions, this runner 40 can be subjected to the packing of this fixing button 43 and move and join with the end face of this packing sleeve 33 toward these breast bench 20 directions, when this this runner 40 of fixing button 43 packings, after making this runner 40 and this

packing sleeve

33 and 43 formation of this fixing button compel admittedly, this runner 40 promptly can't rotate, and make this rotating shaft 30 that the fixing effect of a packing be arranged, can not be subjected to the influence of external force and rotate.

In addition, consult shown in Figure 7ly, the utility model provides a kind of breast bench to adjust another embodiment of the locked instrument of runner, and its major function is identical with last embodiment, so repeat no more, wherein, this packing sleeve 33a is that it is the outside that is fixedly arranged on this breast bench 20 for one lamellar, and its front end is also slightly protruding in this pivot cover portion 31, this packing sleeve 33a is fixedly arranged on this breast bench 20, can avoid this packing sleeve 33a because of stressed excessive rotating, and can increase its locking intensity.
