[0014] Compared with the prior art, the present invention has the following beneficial effects:

[0015] 1. This device can achieve the function of first-level damping adjustment and control by setting a second adjustment device. When the shock-absorbing protective card cover squeezes and compresses the shock-absorbing spring, the shock-absorbing spring squeezes the fixed support ring, so that the fixed support ring and the pressing support plate play an auxiliary buffering adjustment role through the auxiliary support column. At this time, the auxiliary support column can fluctuate up and down in the buffering adjustment ring through the auxiliary buffering piston ring to play a buffering and shock-absorbing role, and the gas pressure inside the buffering adjustment ring can be detected in real time through the second pressure sensor. When the gas pressure inside the buffering adjustment ring is too high, the gas control valve automatically makes the buffering adjustment ring discharge a specified amount of gas outward, and the fluid flow sensor can control the second delivery hose to supplement a specified amount of gas into the inside of the buffering adjustment ring, so that the buffering adjustment ring can play an adaptive support auxiliary buffering shock-absorbing adjustment role for the auxiliary buffering piston ring and the auxiliary support column, so that the damping of this device can be adjusted during use, and it is safe during use and has sufficiently good shock-absorbing and buffering performance.

[0016] 2. This device realizes the function of two-level damping adjustment and control by setting a first adjustment device. When this device approaches the critical point of shock absorption and buffering performance during operation, hydraulic oil can be added to the interior of the buffer adjustment frame through the first delivery hose, and the hydraulic oil can be automatically delivered to the interior of the buffer column. In this process, the first pressure sensor can detect the internal pressure of the hydraulic oil buffer box in real time. When the hydraulic oil pressure inside the buffer column is too high, the hydraulic oil enters the interior of the hydraulic oil buffer box, and at this time, the electric control valve and the gas flow sensor can discharge the specified amount of hydraulic oil in the buffer adjustment frame from the interior of the first delivery hose, which plays a role in pressure relief, so that there is always enough buffer hydraulic oil inside the buffer column, and the amount of hydraulic oil can be automatically adjusted when the pressure is too high. Therefore, the damping of this device can be conveniently adjusted and controlled, so that this device can safely and stably perform shock absorption and buffering.

[0017] 3. This device evenly fixes auxiliary pressing plates on the outer end of the fixed connecting plate, and evenly fixes auxiliary supporting springs on the outer end of the fixed mounting base, so that each auxiliary pressing plate is located directly above each auxiliary supporting spring. Therefore, when the fixed connecting plate and the auxiliary pressing plate move downward instantaneously beyond a specified distance, each auxiliary pressing plate can be squeezed out from the upper end of the auxiliary supporting spring, and by pressing the auxiliary supporting spring, it plays an auxiliary safety buffer and shock absorption role.

[0040] The working principle of embodiment 1 is as follows: the device can be fixedly installed by the fixed mounting base 7, and the device can be connected to a device that needs to be buffered and shock-absorbing by the fixed connecting plate 1. During use, the fixed connecting plate 1 is pressed to make the telescopic shock-absorbing column 4 and the main buffer piston ring 10 move downward along the inside of the buffer column 8, and the inside of the buffer column 8 is filled with hydraulic oil, so that the main buffer piston ring 10 plays an auxiliary and shock-absorbing role when it moves up and down inside the buffer column 8, and at this time, the telescopic shock-absorbing column 4 can press and compress the shock-absorbing spring 5 through the shock-absorbing protective card cover 3, thereby playing an auxiliary shock-absorbing and buffering role, so that the device has sufficient shock-absorbing and buffering performance during use;
