In each figure, 1 is electric hand drill, and 2 be pull bar, and 3 be support, and 4 be transverse axis, and 5 be axis hole, and 6 be tip section pull bar, and 7 be length
Sign, 8 is slightly connect pull bar, and 9 be card.
Embodiment：
The design is described further below in conjunction with the accompanying drawings.
As shown in Fig. 2, Fig. 3, Fig. 4, Fig. 5, the pull bar depth gauge rule of the design includes support 3 and pull bar 2, and pull bar 2 is one kind
Worn by the spring card assembling to match on the light-wall pipe and Ge Jie pipes of more piece gradient-thickness and be connected the tube assembly formed,
It can be condensed to it is very short can also pull into longer, can be used according to specific use occasion to adjust, be most slubbing in its root
The lower end of pull bar 8 is fixedly connected with 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 is with the support 3 in its two-end part by piercing into the oval axis hole 5 to match with transverse axis on support
The connection of interference fit, transverse axis are the oval relative to axle of transverse axis being occurred by external force effect relative to the rotary motion of support
During the oval generation relative motion in hole, the mutual cooperation of transverse axis 4 and axis hole 5 can produce such action character：When running to horizontal stroke
The position that be combined with each other both when length radius on axle ellipse coincides with the length radius on axis hole ellipse can keep one compared with
Stable state, the direction of pull bar that thereby can to transverse axis and thereon or position are adjusted, as shown in Figure 2, Figure 4 shows；In pull bar 2
On, the curvature for the card 9 being equipped with each section from coarse to fine is become larger by small, i.e., the combination tensity between each section pull bar is by thick
To carefully tapering into（The curvature of card 9 is small mean its be bonded the degree of outer tie rod tube wall circumference it is relatively low and in outer tie rod
Between stretching degree it is higher）, such movement effects can be produced by being arranged such：When operation tip section pull bar, outwards extension is completely pulled out
Tip section pull bar always can fully extended first and then secondary details drawing when each section pull bar or backward retraction are fully retracted each section pull bar
Bar is fully extended successively again or tip section pull bar be fully retracted the pull bar of rear details again successively be fully retracted and so on and
Other successively stretching orders are not had, and as shown in Fig. 3, Fig. 5, this thickness section pull bar protracts or returned completely successively completely successively
Contract effectively played a role for the pull bar depth gauge rule of the design without disorder flexible rod assembly design be must
Want, be otherwise then cisco unity malfunction；The digital ascending setting order of length mark 7 on pull bar 2 originates in the tip
The top that this section pull bar is arrived in the root of section pull bar 6 upwards is connected in time root of details pull bar upwards until this section is drawn again after nearby
The setting on the top of bar and so on, as shown in figure 3, the length indication numeral of tip section pull bar altogether for 8 scales be 0-
8cm, the pull bar of secondary details is then 9-16cm, and it is all same long preferably to save by that analogy and often set scale sign;By such as figure
By pull bar depth gauge rule device near the body front end of electric hand drill 1, pull bar is axially parallel to electric hand drill main shaft for citing shown in 1
Direction, the shrinking pull bar depth gauge rule of shape it can put as shown in Figure 1 during without using depth gauge rule（Pull bar is after）；Need to use
When, then operate 180 ° of angles of pull bar rotation and cause direction of the pull bar towards apex point, such as foregoing transverse axis coordinates with the nervous of axis hole ellipse
Effect can cause the location status of pull bar forward backwards all relatively stable so as to be advantageous to the operation of pull bar and use, and operator can be first
Previously draw 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
Size requirement come the pull bar that bounces back, i.e., pull bar is reclaimed on the top that tip section pull bar is pinched with hand successively, now, if the length because of drill bit
Degree is smaller so that the pull bar of tip section is not completely pulled out the situation that can reaches matched apex point yet（Be not in or seldom can
Occur）, it is necessary to operator observe tip section pull bar it is matched and retraction when tip section pull bar and secondary details pull bar between joint part length
Sign numerical value change determines to control；If drill bit it is longer, it is necessary to stretch out tip section pull bar and its under pull bar could be matched in brill
Point, then same is to operate tip section pull bar retraction to bore the length dimension set deeply, for example hole depth requires 3cm, then tip section pull bar 6 is just
Bounce back 3cm, is determined by the length indication of the joint part between tip section pull bar and secondary details pull bar for 3, if retracted length
The retraction time details pull bar that can be then continued more than the length value of tip section setting after tip section is fully retracted, same is by secondary
The length indication numerical value of joint part between details pull bar and the 3rd details pull bar determines, by that analogy, is designed just as original
Foot bar the same play a part of with reference to controlling hole depth, the design of rod assembly that thickness section pull bar protracts or bounced back successively successively
Effectively played a role for it and provide abundant guarantee.It is not difficult to find out, the foot bar of depth gauge rule is changed to more piece by a whole section
The design of the pull bar of gradient-thickness reduces the volume of depth gauge rule, can also without using when change position, be depth gauge rule dress
A kind of useful improvement put.
