finally, the swinging block and the rotating support rotate to the direction opposite to the direction of the impact on the telegraph pole; meanwhile, when the telegraph pole is impacted; the utility pole is hard and not easy to break; the telegraph pole can drive the base disc to swing; the base disc swings to drive the rotating disc to swing; at the moment, the rotating disc swings to drive the base disc to swing around the rotating shaft on the rotating support; 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 telegraph pole; when the fifth connected block moves downward; the fifth connecting block drives the pushing disc to move downwards; pushing the disc to move downwards can extrude liquid in the first hydraulic cylinder; so that the hydraulic pressure in the first hydraulic cylinder becomes large. The third clamping block is used for providing a guiding function for the shaft sleeve. 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 applied to the annular spherical hinge shell is large, the stability of the annular spherical hinge shell is ensured through the weight.

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 base disc swings to drive the rotating disc to swing; at the moment, the rotating disc swings to drive the base disc to swing around the rotating shaft on the rotating support; 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.

When the first telescopic rod 11 and the second telescopic rod 21 swing; the impact force transmitted by the utility pole 3 is large, so that the reaction force of the spherical hinge 24 on the annular spherical hinge shell 28 is relatively large when the first telescopic rod 11 and the second telescopic rod 21 swing; this may cause the annular spherical hinge housing 28 to be subjected to a strong upward pulling force; damage to the annular spherical hinge housing 28; so that the annular spherical hinge shell 28 loses the hinge function; therefore, the lower end of the isolation block 6 is fixed on the soil layer 1; the upper end of the isolation block 6 is arranged at the lower end of the concrete layer 4; the inner wall of the second hydraulic cylinder 32 is symmetrically provided with two guide grooves 46; the upper end of the second hydraulic cylinder 32 is arranged at the lower end of the concrete layer 4 and is positioned in the first square groove 36 on the isolation block 6; two guide blocks 45 are symmetrically arranged on the outer circular surface of the upper end of the hydraulic inner column 42; two second block grooves 44 are symmetrically formed on the outer circular surface of the lower end of the hydraulic inner column 42; the upper end of the hydraulic inner column 42 is arranged in the second hydraulic cylinder 32 through the matching of the two guide blocks 45 and the two guide grooves 46; the lower end of the hydraulic inner column 42 is positioned in the circular hole 35 on the isolation block 6, and two second clamping block grooves 44 at the lower end of the hydraulic inner column 42 are matched with two second clamping blocks 33; two first block grooves 41 are symmetrically formed on the outer circumferential surface of the weight 31; the weight 31 is positioned in the circular hole 35 on the spacer block 6, and the two first clamping block grooves 41 on the weight 31 are matched with the two first clamping blocks 39; when the hydraulic pressure in the first hydraulic cylinder 23 becomes large and the pressure reaches the limit value of the pressure outlet 27; the fluid in the first hydraulic cylinder 23 flows into the second hydraulic cylinder 32 through the hydraulic pipe; the fluid flowing into the second hydraulic cylinder 32 pushes the hydraulic inner column 42; a downward pressure is applied to the hydraulic inner column 42; when the pressure applied to the hydraulic inner column 42 is greater than the thrust of the two fourth springs 43 against the second latch 33; the hydraulic inner column 42 will move downward; the downward movement of the hydraulic inner post 42 will give a downward thrust to the weight 31; when the thrust force applied to the weight 31 is larger than the thrust force of the two third springs 40 on the first clamping block 39; the weight 31 moves downward along the circular hole 35; so that the weight 31 hits the annular spherical hinge shell 28; the stability of the annular spherical hinge shell 28 is enhanced; the first hydraulic cylinder 23 and the second hydraulic cylinder 32 designed by the invention have the function of adding a thrust to the weight 31 through the hydraulic inner column 42; so that the initial speed of the weight 31 becomes fast; the time for the weight 31 to move downward is reduced; the annular spherical hinge shell 28 can be ensured to be timely and stable. In the invention, when the buffer mechanism 2 initially works; the upward pulling force applied to the annular spherical hinge housing 28 is buffered by the elastic force of the second spring 29; the weight 31 ensures the stability of the annular spherical hinge housing 28 when the annular spherical hinge housing 28 is subjected to a large upward pulling force.

The specific implementation mode is as follows: when one uses the utility pole 3 designed according to the present invention; when the utility pole 3 is impacted; the utility pole 3 is hard and not easy to break; the telegraph pole 3 can drive the base disc 7 to swing; the base disc 7 swings to drive the rotating disc 15 to swing; the swinging of the rotating disk 15 brings the base disk 7 to swing around the rotating shaft 13 on the rotating support 9; the base disc 7 swings to drive the first connecting rod 10 which is in the opposite direction to the rotating shaft 13 to move upwards; the first connecting rod 10 drives one end of the first telescopic rod 11 close to the first connecting rod 10 to swing upwards through a spherical hinge 24; when the first telescopic rod 11 swings, the spherical hinge 24 formed by the spherical hinge 24 and the annular spherical hinge shell 28 enables one end of the second telescopic rod 21 far away from the first telescopic rod 11 to swing downwards; one end of the second telescopic rod 21, which is far away from the first telescopic rod 11, swings downwards to drive the fifth connecting square 22 to move downwards; in the invention, the impact force applied to the telegraph pole 3 is sequentially transmitted to the ground through a series of transmissions of the buffer mechanism 2; thereby preventing the foundation on the lower side of the telegraph pole 3 from being damaged by the impact force when the telegraph pole 3 is impacted; thereby protecting the utility pole 3.
