Ratchet quantity on the utility model on fluted disc 4 and lower tooth disk 7 is uniformly distributed and offers by even numbers, as 16 teeth, and can

calibration

2,4,8,16 deciles; As 24 teeth, can

calibration

2,3,4,6,8,12,24 deciles, number of teeth amount can design according to actual requirement by that analogy.Accompanying drawing embodiment is depicted as the number of teeth 16 deciles, as example, operation principleas follows:

As shown in Figure 5, during original position, ratchet 12 coordinates with the ratchet root of lower tooth disk 7, and now positioning head 8 is in by spanner 5 front end 55 jack-up states, and spanner 5 handle bars 5 ' stick together (playing the role of positioning) with notch 53 limits, left side on housing 3; As shown in Figure 6, pull spanner 5 to housing 3 on notch 53 right edge stick together, spanner 5 drives lower tooth disks 7 and upper fluted disc 4, index dial 1 to rotate a tooth angle by ratchet 12, simultaneously positioning head (8) departs from 55 effects of spanner front end, and the compressed spring 10 of positioning head 8 ejects and falls in the decile teeth groove of fluted disc 4 upper fluted disc 4 location; Then spanner 5 is turned back to former original position (being Fig. 5 position), now positioning head 8 is again by spanner 5 front end 55 jack-up, complete 1/16 equation graduation.Pull wrench (5) and continue to repeat aforesaid operations, can complete by that

analogy

8,4,2 equation graduations.As needs complete 8 deciles, spanner (5) need to be repeated to 2 aforesaid operations, complete 1/8 equation graduation.As needs complete 4 deciles, spanner 5 need to be repeated to 4 aforesaid operations, complete 1/4 equation graduation.As needs complete 2 deciles, spanner 5 need to be repeated to 8 complete steps of aforesaid operations, complete 1/2 equation graduation.

The utility model is simple in structure, easily makes, and use production efficiency is high, precision is high, be applicable to most mechanical processing industries, and its versatility is stronger, is beneficial to storage and managenent, can be widely used in various drilling machines, milling machine and miscellaneous equipment and use.
