Although the above structure can solve the technical problems well, the inventor still has room for improvement on the basis of the above structure, particularly because the fixing of the apron 2 cannot be optimized, and the buffering capacity and the fixing capacity of the above device can be further optimized in practical use, particularly for some slight impacts, such as low-speed impact of people or low-speed impact of bicycles and the like, the buffering capacity of the above structure is not strong, so that the injury to people is large, and further improvement is made for the purpose, and the specific scheme is as follows: a first electromagnet 101 with a first coil is arranged on the outer side of the T-shaped groove 56 close to the enclosing plate 2, a movable fixing rod 103 is arranged in the limiting rod 54, an opening 102 is arranged at the position of the T-shaped groove 56 corresponding to the fixing rod 103, a second electromagnet 104 with a second coil is sleeved on the end side of the fixing rod 103 close to the opening 102, a concave third electromagnet 105 is sleeved on the outer end of the fixing rod 103 far away from the enclosing plate 2, the outer end of the fixing rod is embedded in a notch of the third electromagnet 105, the third electromagnet is provided with a vertical coil and a horizontal coil which are sleeved, the first coil, the second coil, the vertical coil and the horizontal coil can be independently controlled by a controller, a fixing cap 106 is arranged on one side of the third electromagnet 105 far away from the fixing rod 103, and a sliding seat 109 which can slide is arranged on one side of the fixing cap 106 close to the enclosing plate 2, the end side of the second spring 107 close to the fixing cap 106 is fixedly provided with a fixing ring 108, one side of the sliding seat 109 close to the third magnet 105 is provided with a permanent magnet, the first spring 52 is a low-elasticity spring, the second spring 107 is a high-elasticity spring, when the device is in actual use, the fixing capacity in the vertical direction is insufficient, and through the cooperation effect of the first electromagnet 101 and the second electromagnet 104, the fixing rod 103 can be driven by the second electromagnet 104 to enter the opening 102, so that the T-shaped block 18 can be vertically limited, more reasonably, a plurality of concave grooves corresponding to the fixing rod 13 can be arranged in the T-shaped block, so that the whole device can realize stable limiting in the vertical direction through the cooperation of the concave grooves and the fixing rod 103, and because the first spring 52 is a low-elasticity spring (low-elasticity spring relative to the second spring), therefore, the first magnet 101 and the second magnet 104 can well realize the matching effect of the fixing rods with lower elasticity, not only can be fixed in a contact manner through the effect of the electromagnet, but also the first fixing rod 103 can be easily pulled out to release the limit through the pulling of the fixing cap 106, so that the first electromagnet and the second electromagnet are well protected, and the service lives of the first electromagnet and the second electromagnet are prolonged; it should be noted that, under normal conditions, the second spring has a high elastic force (high elastic force relative to the first spring), and a non-connection structure is provided between the fixing ring 108 on the second spring 107 and the sliding seat 109, so that the first spring 52 having a low elastic force on all sides functions again, and thus, when a pedestrian or a bicycle collides, the first spring 52 can well achieve buffering, not only does not damage the device, but also has less injury to people, because the first spring 52 can be compressed smoothly under low impact, thereby reducing casualties; however, when the elastic force of the first spring 52 is insufficient to achieve the above-mentioned buffering, the sliding seat 109 can enter into the fixed ring 108, and it should be noted that the sliding seat 109 can slide along the bottom side of the fixed cap 106, and can also move in the fixed cap 106 along the direction in which the fixed rod 103 extends, specifically, because a telescopic structure such as a telescopic sleeve is accommodated in the fixed cap 106, the end of the sliding seat 109 connected with the fixed cap 106 is connected with the telescopic structure such as the telescopic sleeve, in other words, when the fixed rod 103 drives the third electromagnet 105 and the fixed cap to move, the positional relationship between the sliding seat 109 and the fixed ring 108 is actually fixed, and the positional relationship between the first spring 52 and the upright 53 is not changed due to the movement of the fixed cap 106, and a pressure sensor is provided between the first spring 52 and the upright 53, the pressure sensor is connected with the controller, when the pressure signal outputted by the pressure sensor exceeds the threshold value (i.e. the elastic force of the first spring 52 is not enough to buffer), the controller controls the horizontal coil of the third electromagnet 105 (i.e. the horizontal direction in fig. 6, which can also be understood as the direction of elongation of the fixing cap or the vertical direction of the fixing rod 103) to work, so that the third electromagnet 105 can act with the permanent magnet on the sliding seat 109, so that the sliding seat 109 moves towards the fixing ring 108 and enters the fixing ring 108, when the fixing rod 103 acts forwards again, the actual acting force should be the pressure of the first spring and the pulling force of the second spring, and because of the high elastic force of the second spring, the buffer can be increased instantly, and the increase of the force can make the impact of an electric vehicle or a motorcycle or even an automobile, the device has good protection effect, avoids the damage of the device and the injury of personnel, and realizes great reliability and safety. Meanwhile, it should be noted that the threshold may be set according to the impact strength of normal pedestrians and bicycles, so that a suitable first spring is selected to have a suitable first elastic force, and a suitable second spring material and a second elastic force are selected according to the impact of, for example, a motorcycle or an automobile, so as to reduce injury; it should be noted that, in the process of releasing the fixing of the T-shaped block, the sliding seat is usually reset, and the reset position may be a position separated from the fixing ring 108, so that the releasing force may be small, the acting force of the first and second electromagnets is reduced, the current may be small, and it is considered that the releasing may be realized by the movement of the fixing cap. To sum up, through the effect of first electro-magnet, opening, dead lever, second electro-magnet, third electro-magnet, locking cap, second spring, retainer plate, sliding seat etc. can realize the buffering of two kinds of modes of high buffering and low buffering, can deal with the buffering of different situation, improve the protection to personnel simultaneously, greatly improved whole device's stability, reliability and security.
