[0041] The working principle of the present invention is as follows: after the inflatable target prosthesis is inflated, the base 1 is placed below the part where the inflatable target prosthesis contacts the ground, and water is injected into the sliding frame 2 through the water injection pipe 21. Subsequently, the driving motor 125 drives the first rotating wheel 126 to rotate, and the first rotating wheel 126 drives the second rotating wheel 128 to rotate through the rotating belt 127, and the second rotating wheel 128 drives the large gear 129 to rotate, and the large gear 129 engages with the two small gears 124 to rotate, and the small gear 124 drives the half gear 123 to rotate through the connecting rod, and the half gear 123 engages with the tooth groove 122 to drive the connecting plate 121 to slide in the sliding cavity 11. When the teeth of one half gear 123 and the gear are aligned, the connecting plate 121 is rotated. After the groove 122 is separated, the teeth of the other half gear 123 contact the tooth groove 122. At this time, the connecting plate 121 moves in the opposite direction, the large gear 129 continues to rotate, and the connecting plate 121 moves back and forth. The connecting plate 121 drives the sliding frame 2 to move above the base 1. The sliding frame 2 drives the support plate 22 and the sliding tip block 25 to move back and forth under the inflatable target prosthesis. The fixed block 221 and the sliding tip block 25 tear the bottom of the inflatable target prosthesis, simulating the state in the wild where the inflatable target prosthesis is blown by strong wind and rubs against the stones on the ground. When the bottom of the inflatable target prosthesis is torn and damaged, the inflatable target prosthesis will be deformed and collapsed due to insufficient air pressure.

[0042] During the inspection, the motor 241 drives the forward and reverse ball screw 242 to rotate, and the forward and reverse ball screw 242 drives the sliding block 243 to move in the opposite direction, the distance between the two sliding blocks 243 becomes larger, and the sliding block 243 pulls the fixed plate 245 downward through the rotating rod 244, and the fixed plate 245 drives the support plate 22 to move into the inside of the sliding frame 2, and the support plate 22 drives the fixed column 261 to wrap the vertical rod 264, and the total length of the fixed column 261 and the vertical rod 264 becomes shorter, and the support plate 22 is immersed in the water inside the sliding frame 2, and the water flows from the through hole 222 to the support plate 2 2, the fixed block 221 and the sliding tip block 25 are soaked, and the motor 241 drives the forward and reverse ball screws 242 to rotate in opposite directions, shortening the distance between the two sliding blocks 243 and moving the support plate 22 out of the sliding frame 2. At this time, the support plate 22 drives the fixed column 261 to rise, and the vertical rod 264 slides out of the sliding cavity 262. The total length of the fixed column 261 and the vertical rod 264 increases. At this time, the sliding frame 2 drives the support plate 22 and the sliding tip block 25 to move back and forth under the inflatable target prosthesis, simulating the use of the inflatable target prosthesis in the field when the ground is wet and wet.

[0043] The cooling fins in the support plate 22 cool the support plate 22 and the sliding tip block 25 , thereby reducing the temperatures of the support plate 22 and the sliding tip block 25 , simulating outdoor use in winter.

The scope of protection of the present invention is defined by the claims. Those skilled in the art may make various modifications or equivalent substitutions to the present invention within the spirit and scope of protection of the present invention, and such modifications or equivalent substitutions shall also be deemed to fall within the scope of protection of the present invention.
