When the drawstring 70 is installed, take the unilateral take-up mechanism as an example, as shown in Figure 5. By rotating the adjusting head 84, the first screw 81 is rotated, and the interlocking member 82 is moved along the axial direction of the first screw 81. The moving direction of the limiting member 82 can be adjusted according to the rotating direction of the adjusting head 84, thereby adjusting the adjustment. When the tightening wheel 83 moves toward the adjusting head 84, the distance between the adjusting wheel 83 and the rear pulley 60 of the body 13 is increased, thereby tightening the pulling rope 70, lifting the pulling rope 70 and actively The friction between the wheels 40, especially when the mask 14 is a tarpaulin or the cover 14 is subjected to a large pulling force, and the problem of idling between the driving wheel 40 and the pulling cord 70 is avoided.

When the cover is required to be retracted, as shown in FIGS. 3 and 6, the power source 21 is activated to sequentially drive the drive wheel 220, the transmission member 221 and the transmission wheel 222, and the transmission wheel 222 rotates the transmission shaft 23, The two driving wheels 40 that drive the two retracting mechanisms rotate, and then the pulling rope 70 rotates. When the pulling rope 70 rotates, the pulling rope 70 moves the linking member 92 toward the head 11 via the two fixing members 91, and simultaneously drives the vehicle body. The linking member 92 on both sides of the 13 moves along with one end of the mask 14 toward the head 11 to achieve the effect of retracting the mask. On the contrary, only the power source 21 needs to be reversely rotated, and the driving wheel 220, the transmission member 221, the transmission wheel 222, the transmission shaft 23, the driving wheel 40 and the pulling rope 70 are reversely rotated in the reverse direction, that is, the two fixing members 91 are driven. Together with the cover 14 moving toward the rear of the body, the effect of the cover 14 covering the top of the body 13 is achieved.
