In each figure, 1 is electric hand drill, and 2 is pull bar, and 3 is support, and 4 is transverse axis, and 5 is axis hole, and 6 is tip section pull bar, and 7 is length
Sign, 8 slightly to connect pull bar, and 9 is card.
Specific embodiment：
Below in conjunction with the accompanying drawings the design is described further.
As shown in Fig. 2, Fig. 3, Fig. 4, Fig. 5, the pull bar depth indicator of the design includes support 3 and pull bar 2, and pull bar 2 is one kind
The tube assembly of linking is worn by the spring card assembling matched on the light-wall pipe and Ge Jie pipes of more piece gradient-thickness,
It can be condensed to it is very short can also pull into longer, use can be adjusted according to specific use occasion, in its root i.e. most slubbing
The lower end of pull bar 8 is fixedly connected a transverse axis 4 into symmetrical shape, and transverse axis 4 is rolled into the ellipse for leaving gap by spring steel plate
Form, transverse axis 4 and the support 3 in its two-end part are by the oval axis hole 5 matched with transverse axis that pierces on support
Nervous connection, transverse axis are the ellipse of transverse axis relative to axis hole the rotary motion that occurs relative to support is acted on by external force
During oval generation relative motion, transverse axis 4 can produce such action character with cooperating for axis hole 5：It is ellipse when transverse axis is run to
Length radius on circle coincide with axis hole ellipse on length radius when both the position that be combined with each other can keep one it is more stable
State, the direction of pull bar that thereby can to transverse axis and thereon or position be adjusted, as shown in Figure 2, Figure 4 shows；On pull bar 2,
The curvature of card 9 being equipped with each section from coarse to fine is become larger by little, i.e., respectively save combination tensity between pull bar by slightly to
Carefully taper into（The curvature of card 9 is little mean its laminating outer tie rod tube wall circumference degree it is relatively low and between outer tie rod
Stretching degree it is higher）, it is arranged such and can produces such movement effects：When operation tip section pull bar, outwards extension is completely pulled out respectively
When section pull bar or backward retraction are fully retracted each section pull bar tip section pull bar always can fully extended first and then secondary details pull bar
Fully extended successively again or tip section pull bar be fully retracted after time details pull bar again successively be fully retracted and so on and not
Have other priorities and stretch out order, as shown in Fig. 3, Fig. 5, this thickness section pull bar protracts completely successively or is fully retracted successively
It is necessary for the pull bar depth indicator of the design effectively plays a role without disorder flexible rod assembly design
, otherwise it is then cisco unity malfunction；The digital ascending setting order of length mark 7 on pull bar 2 originates in tip section
The root of pull bar 6 arrives the top of this section pull bar upwards and is connected in time root of details pull bar after nearby again upwards until this section pull bar
Top and so on setting, as shown in figure 3, the length indication numeral of tip section pull bar is 0-8cm for 8 scales altogether,
The pull bar of secondary details is then 9-16cm, often saves set scale sign by that analogy and preferably all same long;By such as Fig. 1 institutes
Show and illustrate by pull bar depth indicator device near the body front end of electric hand drill 1, the side for being axially parallel to electric hand drill main shaft of pull bar
To without using the shrinking pull bar depth indicator of shape putting as shown in Figure 1 during depth indicator（Pull bar is towards after）；Need to use
When, then operate pull bar to rotate 180 ° of angles and cause direction of the pull bar towards apex point, the such as aforementioned transverse axis nervous cooperation oval with axis hole
Effect can cause all relatively stable operation and use so as to be conducive to pull bar of pull bar location status forward backwards, and operator can be first
Previously drawn tip section pull bar 6, pull bar from fine to coarse can successively forward it is fully extended until matched in apex point position, then according to hole depth
Dimensional requirement come the pull bar that bounces back, i.e., pull bar is reclaimed on the top for pinching tip section pull bar with handss successively, now, if because of the length of drill bit
Degree is less so that the pull bar of tip section is not completely pulled out the situation that can just reach matched apex point yet（Be not in or seldom can
Occur）, it is necessary to operator observation tip section pull bar it is matched and retraction when between tip section pull bar and secondary details pull bar joint part length
Indicate change in value to control determination；If drill bit is longer, need to stretch out tip section pull bar and its under pull bar could be matched in brill
Point, then same is the length dimension for operating tip section pull bar retraction to bore deep setting, and such as hole depth requires 3cm, then tip section pull bar 6 is just
Retraction 3cm, is 3 determining, if retracted length by the length indication of the joint part between tip section pull bar and secondary details pull bar
More than the retraction time details pull bar that the length value of tip section setting then can continue after tip section is fully retracted, same is by secondary
The length indication numerical value of the joint part between details pull bar and the 3rd details pull bar determining, by that analogy, just as original design
Chi bar it is the same play a part of with reference to control hole depth, thickness section pull bar protract successively or bounce back successively rod assembly design
Effectively play a role for which and provide fully guarantee.It is not difficult to find out, the chi bar of depth indicator is changed to into more piece by a whole section
The design of the pull bar of gradient-thickness reduces the volume of depth indicator, can with without using when change position, be depth indicator dress
A kind of useful improvement put.
