The first locking device and the second locking device are respectively fixedly arranged on the upper side plate 19 at two sides of the recessed part, the guide block 10 is arranged on the recessed part of the upper side plate 19, so when the rotating arm 20 is at the guiding position (namely, when the rotating arm 20 is in the vertical state), the bottom wall 29 of the recessed part is vertical to the front side plate 15 and the rear side plate 31, so that the bottom wall 29 of the recessed part is at the horizontal position, the guide block 10 can extend upwards along the vertical direction, and the first locking device and the second locking device at two sides of the recessed part are inclined towards the front side of the rotating arm 20, and the guiding of the guide block 10 is not influenced; when the turning arm 20 is in the locking position, the upper side plates 19 fixing the first and second locking means (i.e. the upper side plates 19 on both sides of the recess) are in a horizontal position, while the bottom wall 29 of the recess is in an inclined position (when the guide block 10 has been retracted into the turning arm 20, the locking of the rocket by the first and second locking means is not affected), that is, when the rocket is locked using the first and second locking means, the upper side plates 19 fixing the first and second locking means are in a horizontal position, while when the guide block 10 is oriented, the upper side plates 19 fixing the first and second locking means are turned from a horizontal position to an inclined position, that is, the first and second locking means are inclined to the front side of the turning arm 20, without affecting the orientation of the guide block 10.

The invention integrates the guiding and positioning functions, when the rotating arm 20 is in a vertical state, the guide block 10 extends out, and the accurate guiding in the front and back direction and the left and right direction of the rocket can be realized in the rocket hoisting process; when the rotating arm 20 is in an inclined state, the locking head end 5 extends out to press the rocket locking convex block on the rocket, so that the rocket is locked in the front and back direction of the rocket and in the up-and-down direction of the rocket.

According to the invention, through manual operation, the lifting guide and rocket locking states can be switched rapidly and reliably, so that the lifting transshipment efficiency of the rocket is improved, and the space for independently installing the guide mechanism is saved. The invention is not only suitable for the transport vehicle loading the rockets of different models, but also suitable for the special launching vehicle launching the rockets of different models.

The invention has the following beneficial effects: the rocket locking mechanism integrates a guiding and positioning function, and can realize two functions of rocket hoisting and guiding and rocket locking; secondly, a guide mechanism is not mounted in the transport vehicle, so that the space is saved; the arrow locking mechanism manually realizes the switching of two states of guiding and arrow locking, and is simple to operate and convenient to maintain.
