Embodiment
When needs detection vehicle steering turn around parameters when, first detector is arranged in main body platform 6 upper surface
On the center steering angle instrument installing hole 8 in portion, being arranged on by vehicle afterwards in main body platform 6, then workman is by the insertion end of ratchet spanner
It is inserted in adjustment hole 9, pulls spanner simultaneously, the insertion end of wrench is disposed with the square rotation hole with driving gear 14 and matches
Insert structure, pull spanner counterclockwise and driving gear 14 can be made to rotate counterclockwise, driving gear 14 rotates so that nibble with it
The left tooth bar 13 and the right telescopic arm 4 that close move toward main body platform 6 direction, simultaneously because be mounted with ratchet 16, and ratchet 16 and driving tooth
Wheel 14 engagement, can cause driving gear 14 to rotate clockwise, it is to avoid left telescopic arm 3 and right telescopic arm 4 outward movment, Zuo Shen
Contracting arm 3 and right telescopic arm 4 rotate along with driving gear 14 and draw close toward detected automobile, until on left cross bar 1 and right cross bar 2
Rubber antiskid clamp 11 and automobile laminating are off rotating driving gear 14, start detector simultaneously and detect automobile, complete
After becoming detection, workman presses unblock button 10, unlocks button 10 and power transmission shaft 17 can be made to move down, and power transmission shaft 17 moves down so that ratchet
15 move down, and ratchet 15 misplaces with driving gear 14, now can control driving gear 14 by ratchet spanner and turn clockwise
Dynamic so that rubber antiskid clamp 11 does not leans on mutually with automobile, change the new automobile needing detection, repeat the above steps afterwards, enter
Row detects next time, is all extended by driving gear 14 controller due to left telescopic arm 3 and right telescopic arm 4 and shortens, thus left
Telescopic arm 3 and right telescopic arm 4 can be synchronized with the movement, and improve the degree of accuracy of detection, rotate driving tooth by ratchet spanner simultaneously
Wheel 14 facilitates the operation of whole device, by installing rubber antiskid clamp 11, it is possible to well avoid clamp to contact with automobile
It is damage car, simultaneously by installing ratchet 15, it is possible to function well as the left telescopic arm 3 of control and the feeding side of right telescopic arm 4
To feature, enable to workman simultaneously and avoid operational error.
