[0018] When using the electric vehicle design component measuring device, first choose to use a steel ruler 5 or a tape measure 7 for measurement according to different measurement requirements. When choosing the steel ruler 5 for measurement, pull the steel ruler 5 outward, and the steel ruler 5 moves stably to the outside of the protective cover 1 through the pull-back mechanism 4. When the steel ruler 5 moves to the outermost side, the pull-back mechanism 4 is clamped, and the steel ruler 5 can be used for measurement at this time. After the steel ruler 5 is measured, the control end of the pull-back mechanism 4 can be rotated, and the pull-back mechanism 4 can drive the steel ruler 5 to move into the support box 3, and the support box 3 can protect the steel ruler 5. If the tape measure 7 is to be used for measurement, pull the tape measure 7 outward to a specified length, and the winding mechanism 6 can limit the tape measure 7 to be received in the support box 3. If the tape measure 7 is to be wound up, pull the control end of the winding mechanism 6, and the winding mechanism 6 can wind up the tape measure 7 under the action of elastic force, and the support box 3 can protect the tape measure 7.

[0019] like Figure 1 As shown, as a preferred embodiment of the utility model, the pulling back mechanism 4 includes: a sliding rod 41, both ends of which are fixedly connected to the inner wall of the protective sleeve 1, a slide plate 42 is sleeved on the sliding rod 41, one end of the steel ruler 5 arranged in the protective sleeve 1 is fixedly connected to the slide plate 42, and a return spring 43 for pulling the steel ruler 5 into the protective sleeve 1 is fixedly connected between the slide plate 42 and the inner wall of the protective sleeve 1; a clamping assembly 44, which is fixedly installed on the inner wall of the protective sleeve 1, and the clamping assembly 44 is cooperated with a clamping rod 45 fixed on the slide plate 42, and the clamping rod 45 is provided with a clamping slot, and the clamping assembly 44 can enter the clamping slot opened by the clamping rod 45 to clamp the clamping rod 45.

[0021] When the steel ruler 5 is used for measurement, the steel ruler 5 is pulled outward, and the steel ruler 5 drives the slide plate 42 and the clamping rod 45 to slide along the slide rod 41 and compress the reset spring 43. When the steel ruler 5 is fully pulled out, the clamping rod 45 enters the clamping groove. After the clamping slot opened by the clamping rod 45 is flush with the clamping block 447, the push spring 448 can push the slide plates 445 and the clamping block 447 on both sides to approach each other. The clamping blocks 447 on both sides can enter the clamping slot when they approach each other, so that the clamping rod 45 can be locked. After the measurement of the steel ruler 5 is completed, the turning handle 442 is turned, and the turning handle 442 drives the gear 443 to rotate. The rotation of the gear 443 drives the racks 444 on both sides to move away from each other. The racks 444 on both sides can push the slide plates 445 and the clamping blocks 447 on both sides to move away from each other, and the clamping blocks 447 can be separated from the clamping slot.

[0024] When using the tape measure 7 for measurement, the tape measure 7 is pulled outward, and the tape measure 7 drives the winding drum 64, the turntable 63 and the shaft rod 61 to overcome the resistance of the locking block 653 and rotate clockwise. At the same time, the torsion spring 62 generates a reset elastic force, and the locking block 653 can limit the counterclockwise rotation of the turntable 63, so that the tape measure 7 can be used for measurement. After the measurement is completed, pull the handle 652, and the handle 652 allows the pull rod 651 to drive the locking block 653 to disengage from the locking groove and compress the compression spring 654.
