As shown in Figures 1 to 7, the quick-release safety seat includes a fixed seat 1, a seat body 2, and a mounting plate 3 arranged between the fixed seat 1 and the seat body 2. The fixed seat 1 is fixedly connected to the vehicle body, the mounting plate 3 is fixedly connected to the seat body 2, and the mounting plate 3 is slidably connected to the fixed seat 1. Specifically, the fixed connection can be a bolt and nut connection or welding. The fixed seat 1 has symmetrical guide rails 11 on both sides, and the two guide rails 11 are provided with a plurality of limiting holes 111. The bottom of the mounting plate 3 is provided with a locking member 4 that cooperates with the limiting hole 111 to lock or unlock the mounting plate 3. The locking member 4 includes a left limit rod 41, a right limit rod 42, a push-pull rod 44 and two connecting arms 47. One end of the two connecting arms 47 is hinged to the push-pull rod 44, and the other end is hinged to the left limit rod 41 and the right limit rod 42 respectively. When the push-pull rod 44 is pulled, the push-pull rod 44 drives the left limit rod 41 and the right limit rod 42 to move toward the center so that the left limit rod 41 and the right limit rod 42 leave the limit hole 111 to unlock the mounting plate 3; when the drag rod is pushed, the push-pull rod 44 drives the left limit rod 41 and the right limit rod 42 to slide to both sides and extend into the limit hole 111 to lock the mounting plate 3. The seat is adjusted by controlling the sliding of the left and right limit rods 42. The left and right limit rods 42 will not cause the seat to shake during use due to wear during use, thereby improving the stability and safety of the seat, and the adjustment is simple and convenient.

As shown in Fig. 3, Fig. 4 and Fig. 5, the locking member 4 further comprises a sleeve 45 and a return spring 43. The inner ends of the left limit rod 41 and the right limit rod 42 extend into the sleeve 45. The return spring 43 is located at the inner ends of the left limit rod 41 and the right limit rod 42 and exerts an outward elastic force on the left limit rod 41 and the right limit rod 42. The left limit rod 41 and the right limit rod 42 can slide in the sleeve 45. The sleeve 45 has a sliding groove inside. The ends of the left limit rod 41 and the right limit rod 42 have a slider matching the shape of the sliding groove. Therefore, the two ends of the sleeve 45 have connecting holes for the left limit rod 41 and the right limit rod 42 to pass through, and the connecting holes are connected to the sliding groove. The sleeve 45 plays a role in installing and connecting the left limit rod 41 and the right limit rod 42 and guiding during the sliding process to avoid the left limit rod 41 and the right limit rod 42 from sliding inconsistently and causing jamming during the sliding process. The return spring 43 is used to provide elastic force to the left limit rod 41 and the right limit rod 42. When the push-pull rod 44 is pulled, the left limit rod 41 and the right limit rod 42 move toward the center of the sleeve 45 to squeeze the spring. At this time, the left limit rod 41 and the right limit rod 42 disengage from the limit hole 111 to release the lock on the mounting plate 3. When the push-pull rod 44 is released, the left limit rod 41 and the right limit rod 42 slide toward the outer end under the action of the elastic force and extend into the limit hole 111 to lock the mounting plate 3.

Preferably, a handle 441 is provided at one end of the push-pull rod 44, and the handle 441 is rotatably connected to the push-pull rod 44. The handle 441 extends out of the fixed seat 1.
