At this time, the pivoting pusher 160 is disengaged from the pin 144 and relatively rotated toward the pin 144.

When the driver pulls the swinging member 150 through the cable 40 again and rotates with the second pivot axis 118, the pivoting pusher 160 pushes the pin 144 to disengage the stop portion 142 of the lock plate 140. The second stop 138 of the plate 130 is limited. At this time, the hood collision hook 30 will move from a locked first position S to a completely unlocked second position R, as shown in FIG. Thus, the hood collision hook 30 is completely disengaged from the locking portion 132 of the gusset plate 130 and the locking groove 111 to be fully opened.

When the hood 20 is reversed to form a locking relationship with the locking mechanism 100 of the present embodiment, the hood collision hook 30 is re-moved from the fully unlocked second position R to the initial position T (ie, the fully locked state). , as shown in Figure 6 and Figure 7. Since the radius of rotation of the second stopping portion 138 of the gusset 130 is greater than the radius of rotation of the first stopping portion 134, the pin 144 must be pushed through the pivoting pusher 160 on the oscillating member 150 to move further away. The restriction of the stop portion 142 of the lock plate 140 thus achieves a two-stage safety unlocking operation.

When the double pull-type locking mechanism 100 of the embodiment is driven, the driver does not need to walk out of the vehicle 10 to pull the safety hook of the hood 20 (not shown), so that the hood 20 can be The hood crash hook 30 is completely disengaged from the locking relationship of the latch mechanism 100. That is to say, the two-stage operation locking mechanism 100 is completely realized in the vehicle 10, and the operation is simpler and easier.
