The lower end of the telegraph pole is provided with a base disc; four buffer mechanisms are uniformly distributed on the outer circumferential surface of the base disc in the circumferential direction;

the lower end of the third telescopic rod is arranged on the lower end surface of the first cylindrical groove; the annular spherical hinge shell is arranged at the upper end of the third telescopic rod; a second spring is arranged between the outer circular surface of the annular spherical hinge shell and the lower end surface of the first cylindrical groove; the first support is fixed on the soil layer; the first telescopic rod and the second telescopic rod are arranged on the annular spherical hinge shell through spherical hinges; the side surface of the upper end of the fifth connecting block is arranged at the other end of the second telescopic rod; the lower end of the first hydraulic cylinder is fixed on the soil layer; the upper end of a pushing disc in the first hydraulic cylinder is connected with the lower end of the fifth connecting square block; for the oscillating mechanism; the lower side of one end of the swinging block is provided with an embedded groove; two limiting grooves are symmetrically formed in two sides of the lower end of the nesting groove; the lower side of one end of the limiting block is provided with an inclined plane; one ends of the two limiting blocks, which are not provided with inclined planes, are respectively arranged in the two limiting grooves;

when the utility pole is impacted; the utility pole is hard and not easy to break; the telegraph pole can drive the base disc to swing; the swinging of the base disc can lead the swinging block in a corresponding swinging mechanism in the eight swinging mechanisms to incline; two limit blocks on the swinging block can be contacted with the rotating shaft on the rotating support in the swinging fast-tilting process; thereby enabling the two limit blocks to move towards the inner sides of the limit grooves; when the two limiting blocks are all moved into the corresponding limiting grooves; the rotating shaft can be clamped in the embedding groove; at the moment, the two limiting blocks move out of the limiting grooves under the action of the corresponding first springs; the two limiting blocks and the nested slots form a closed rotating shaft sleeve; a rotating shaft sleeve consisting of two limiting blocks and an embedding groove is matched with the rotating shaft to form a rotating pair; the base disc can swing around the relative rotating shaft through the rotating pair; the base disc swings to drive the first connecting rod which is in the opposite direction to the rotating shaft to move upwards;

When the base disc swings around the relative rotating shaft; the first connecting rod and the first telescopic rod which are positioned in the same direction with the rotating shaft can slightly swing; but the swing of the first connecting rod and the first telescopic rod is under the action of a spherical hinge formed by the first connecting rod and the first telescopic rod and the expansion and contraction of the first telescopic rod; the first telescopic link can not drive the second telescopic link to swing.

When the first telescopic rod and the second telescopic rod swing; the impact force transmitted by the telegraph pole is large, so that the reaction force of the spherical hinge on the annular spherical hinge shell is relatively large when the first telescopic rod and the second telescopic rod swing; therefore, the annular spherical hinge shell can be subjected to a strong upward pulling force; damaging the annular spherical hinge shell; so that the annular spherical hinge shell loses the hinging function; therefore, the lower end of the isolation block is fixed on the soil layer; the upper end of the isolation block is arranged at the lower end of the concrete layer; two guide grooves are symmetrically formed in the inner wall of the second hydraulic cylinder; the upper end of the second hydraulic cylinder is arranged at the lower end of the concrete layer and is positioned in the first square groove on the isolation block; two guide blocks are symmetrically arranged on the outer circular surface of the upper end of the hydraulic inner column; two second clamping block grooves are symmetrically formed in the outer circular surface of the lower end of the hydraulic inner column; the upper end of the hydraulic inner column is arranged in the second hydraulic cylinder through the matching of the two guide blocks and the two guide grooves; the lower end of the hydraulic inner column is positioned in a circular hole on the isolating block, and two second clamping block grooves at the lower end of the hydraulic inner column are matched with the two second clamping blocks; two first block grooves are symmetrically formed in the outer circular surface of the heavy block; the heavy block is positioned in the circular hole on the isolation block, and the two first clamping block grooves on the heavy block are matched with the two first clamping blocks; when the hydraulic pressure in the first hydraulic cylinder becomes large and the pressure reaches the limit value of the pressure outlet; the liquid in the first hydraulic cylinder flows into the second hydraulic cylinder through the hydraulic pipe; the liquid flowing into the second hydraulic cylinder can push the hydraulic inner column; applying a downward pressure to the hydraulic inner column; when the pressure applied to the hydraulic inner column is greater than the thrust of the two fourth springs to the second fixture block; the hydraulic inner column moves downwards; the downward movement of the hydraulic inner column can give a downward thrust to the weight block; when the thrust force borne by the weight is greater than the thrust force of the two third springs to the first clamping block; the weight block moves downwards along the circular hole; so that the weight blocks are hammered towards the annular spherical hinge shell; the stability of the annular spherical hinge shell is enhanced; the first hydraulic cylinder and the second hydraulic cylinder are designed to add a thrust to the weight block through the hydraulic inner column; so that the initial speed of the weight is increased; the time for the weight to move downwards is reduced; the annular spherical hinge shell can be ensured to be stable in time. In the invention, when the buffer mechanism initially works; the upward tension on the annular spherical hinge shell is buffered through the elastic force of the second spring; when the upward pulling force on the annular spherical hinge shell is large, the stability of the annular spherical hinge shell is ensured through the weight block; the eight swing mechanisms designed by the invention have the function that when the impact point of the telegraph pole is positioned between the two adjacent buffer mechanisms; one of the eight swinging mechanisms corresponding to the opposite direction of the impact point can play a role; so that the buffer mechanism can be smoothly performed.

When people use the utility pole designed by the invention; when the utility pole is impacted; the utility pole is hard and not easy to break; the telegraph pole can drive the base disc to swing; the swinging of the base disc can lead the swinging block in a corresponding swinging mechanism in the eight swinging mechanisms to incline; two limit blocks on the swinging block can be contacted with the rotating shaft on the rotating support in the swinging fast-tilting process; thereby enabling the two limit blocks to move towards the inner sides of the limit grooves; when the two limiting blocks are all moved into the corresponding limiting grooves; the rotating shaft can be clamped in the embedding groove; at the moment, the two limiting blocks move out of the limiting grooves under the action of the corresponding first springs; the two limiting blocks and the nested slots form a closed rotating shaft sleeve; a rotating shaft sleeve consisting of two limiting blocks and an embedding groove is matched with the rotating shaft to form a rotating pair; the base disc can swing around the relative rotating shaft through the rotating pair; the base disc swings to drive the first connecting rod which is in the opposite direction to the rotating shaft to move upwards; the first connecting rod drives one end of the first telescopic rod close to the first connecting rod to swing upwards through the ball hinge; the first telescopic rod swings to enable one end, far away from the first telescopic rod, of the second telescopic rod to swing downwards through a spherical hinge formed by the spherical hinge and the annular spherical hinge shell; one end of the second telescopic rod, which is far away from the first telescopic rod, swings downwards to drive the fifth connecting square block to move downwards; impact force borne by the telegraph pole is sequentially transmitted to the ground through a series of transmissions of the buffer mechanism; therefore, when the telegraph pole is impacted, the impact force damages the foundation on the lower side of the telegraph pole; thereby protecting the utility pole.
