The middle part of the posture adjusting beam 51 is provided with a posture adjusting beam pin seat 45 which is in hinged connection with a capital adjusting beam hinge shaft 34 at the middle part of the platform frame 44. Five positioning tool pin seats 47 are distributed on the posture adjusting beam 42. The positioning tool 48 is fixed on the posture adjusting beam 42 through the positioning tool pin seat 47 and the positioning tool pin shaft 49, the positioning tool pin shaft 49 penetrates through the positioning revolution pin seat 48, the positioning tool pin shaft 49 rotates by 90 degrees, locking can be achieved, the operation can be carried out by one hand, and the operation is convenient. Different positioning tool pin bases 47 can be selected according to different spring types. Note that the missile wing position should be near the attitude adjustment beam pin mount 45 when the missile is installed. The positioning tool 48 is provided with a roller group, so that the axial rotation and posture adjustment of the projectile body can be realized, and the effects of supporting and fixing the projectile body can be realized. When the package is not used, the positioning tool 48 can be taken down and hung downwards at the front end of the posture adjusting beam 51. A rear locking hook 46 and a front locking hook 52 are fixed on the lower sides of the front and rear ends of the posture adjusting beam 51. When the scissor fork lifting mechanism 4 falls back, the movable scissor fork linear guide rail 23 and the fixed scissor fork linear guide rail 25 move away from each other, and when the falling height is lower than the bullet hanging height by a certain distance (the distance is a specific numerical value), the rear lock hook 46 and the front lock hook 52 are respectively engaged with the movable scissor fork linear guide rail 23 and the fixed scissor fork linear guide rail 25, and the horizontal and pitching posture adjusting functions are automatically locked. Particularly, the sliding support buffer sleeves 36 are sleeved on the static scissor linear guide rail 25 and the movable scissor linear guide rail 23, and at the moment, the rear lock hook 46, the movable scissor linear guide rail 23, the front lock hook 52 and the static scissor linear guide rail 25 are engaged through the sliding support buffer sleeves 36, so that the friction force is increased, and the stability of horizontal locking is improved. Meanwhile, when the rear locking hook 46 and the front locking hook 52 are respectively engaged with the movable scissor linear guide rail 23 and the static scissor linear guide rail 25, the pulley 41 in the posture adjusting platform sliding groove 42 is extruded on the rubber buffer block 43, and the rubber buffer block 43 generates certain deformation, so that the friction force is greatly increased, and the stability of horizontal locking is further enhanced. When the scissor fork lifting mechanism 4 is lifted, the static scissor fork linear guide rail 25 and the moving scissor fork linear guide rail 23 move oppositely, and when the lifting height reaches a certain value (the distance is a specific value), the rear lock hook 46 and the front lock hook 52 are separated from the moving scissor fork linear guide rail 23 and the static scissor fork linear guide rail 25 respectively, so that the posture adjusting function is automatically unlocked. Specifically, the front latch hook 52 has a downward protrusion at the opening, and the rear latch hook 46 has a horizontal surface with a length slightly exceeding the length of the rear attitude adjustment platform chute 42 of the platform frame 44. During the lifting operation, the front latch hook 52 and the stationary scissor linear guide 25 are kept in an engaged state due to the protrusion on the front latch hook 52, and the movable scissor linear guide 23 slides forward on the horizontal hook seat of the rear latch hook 46. At this time, the horizontal hook seat of the rear lock hook 46 and the moving scissor fork linear guide rail 23 are still in an extrusion state under the weight action of the pitching posture-adjusting beam 7 and the projectile body, and the locking is still kept in the horizontal direction. When the lifting platform is lifted to a certain height, in the posture adjusting platform sliding groove 42 at the rear side of the platform frame 44, the pulley 41 slides forwards to the opening end part of the posture adjusting platform sliding groove 42, the vertical shaft on the sliding support 40 and the posture adjusting platform sliding groove 42 are mutually clamped, the pulley 41 cannot slide forwards continuously, and at the moment, the relative motion of the movable scissor linear guide rail 23 and the platform frame 44 is stopped. When the lifting operation is continued, the platform frame 44 moves forward relative to the static scissor linear guide rail 25, and at the moment, the static scissor linear guide rail 25 is separated from the front locking hook 52, so that automatic unlocking is realized. This embodiment realizes an automatic unlocking function of a certain height. Meanwhile, four pitching dampers 50 are fixed on two sides of the posture adjusting beam 51, are symmetrically arranged about the posture adjusting beam hinge shaft 34, and are in one-to-one correspondence with the damper bearing seats 35 on the platform frame 44. In the lifted state, an operator lifts and presses the projectile body up and down at the front end or the rear end of the projectile body, and then the pitching posture-adjusting operation of the ammunition and the pitching posture-adjusting beam 7 can be realized. In the reset state, the pitch damper 50 automatically adjusts the posture adjustment beam 51 to be restored to the horizontal state.

As shown in fig. 8, the drawbar 1 is formed by connecting a drawbar body 54 and a drawbar connecting rocker 56. The upper end of the drawbar body 54 extends out of the grip 55, and can be pulled by hand, and the pull ring 53 can be hooked on a traction seat of a tractor to realize mechanical traction. An opening plate 57 is fixed at the lower end of the draw bar body 54, the quick connection with the draw bar connecting rocker arm 56 can be realized by closing the opening plate 57, the operation can be performed by one hand, and the operation is convenient. The drawbar body 54, when removed, may be placed on the drawbar rest 11 of the travel chassis 3. The other end of the traction rod connecting rocker arm 56 is connected with a steering rocker arm 9 of the walking chassis 3 through a hexagonal flange surface locking nut 19, and the traction and steering effects are achieved on the vehicle body 2.

The above specific implementation mode greatly improves the simplified operation, the efficiency, the light weight and the safety. In the aspects of simplifying operation and improving efficiency, the manual unlocking/locking posture-adjusting limit function is eliminated, and the functions of automatically releasing the posture-adjusting limit during lifting, automatically resetting and locking the posture-adjusting limit during falling back are realized. The operation steps are simplified, the subsequent potential safety hazard caused by forgetting unlocking or locking, adjusting the posture and limiting in the operation process is eliminated, and the man-machine efficiency is greatly improved. Meanwhile, a modular design concept is adopted, and the modules have specific matching relation, so that the module can be modified and developed on the basis of the existing module, and strong product vitality is formed.
