Because the higher the height of the iron block 10 is, the larger the impact force is, and the different detection results are, people can adjust the height of the first sliding block 5 according to the requirements for different toughness of the anti-falling net, when the toughness of the anti-falling net required by people is larger, the output shaft of the driving motor 152 is started to rotate reversely, the output shaft of the driving motor 152 drives the screw 153 to rotate reversely, so that the screw 153 drives the thread bushing 154 to move upwards, and further drives the first sliding block 5 to move upwards, the first sliding block 5 moves upwards to drive the second swinging rod 131 and the second reel 132 to move upwards, and further drives the third sliding sleeve 135 to move upwards through the second pull rope 134, at the moment, the fifth spring 136 is stretched, when the first sliding block 5 moves upwards to the height required by people, people close the driving motor 152, and then let the iron block 10 detect the toughness of the anti-falling net, when the toughness of the anti-falling net required by people is smaller, can start driving motor 152, driving motor 152 output shaft drives screw rod 153 corotation, screw rod 153 drives thread bush 154 and moves down, make thread bush 154 drive first slider 5 and move down, first slider 5 moves down and drives second pendulum rod 131 and second reel 132 and move down, fifth spring 136 resets this moment, drive third sliding sleeve 135 and move down and reset, after first slider 5 moves down to the required height of people, people close driving motor 152, so, alright adjust the height of first slider 5, and then reach the mesh of preventing weighing down to detect to different toughness.

Referring to fig. 3, 15 and 16, the iron block buffering device further includes a buffering mechanism 16, the buffering mechanism 16 is used for buffering the iron block 10, the buffering mechanism 16 includes a buffering plate 161, a second fixing block 162 and an eighth spring 163, the second fixing block 162 is welded on the front side and the rear side of the lower portion of the frame body 2, the buffering plate 161 is slidably connected to the upper portion of the inner portion of the frame body 2, the buffering plate 161 is used for buffering the iron block 10, and the eighth spring 163 is connected between the tops of the two second fixing blocks 162 and the bottom of the buffering plate 161.

When the toughness of preventing weighing down the net is not closed, iron plate 10 drops down, prevent weighing down the net and can break, iron plate 10 drops down to buffer board 161 on, drive buffer board 161 and move down, eighth spring 163 is compressed this moment, so, buffer board 161 can cushion iron plate 10, avoid iron plate 10 directly to pound on support 1, prevent that support 1 from being damaged by iron plate 10, and then avoid causing economic loss, when iron plate 10 moves up and resets, eighth spring 163 resets this moment, drive buffer board 161 and move up and reset.

The above description is only for the purpose of illustrating the preferred embodiments of the present invention and is not to be construed as limiting the invention, and any modifications, equivalents, improvements and the like that fall within the spirit and principle of the present invention are intended to be included therein.
