The first piston 213 is slidably disposed in the cylinder 211, the limit plate 217 is fixedly connected to the cylinder 211 by bolts, and the limit plate 217 covers the opening of the cylinder 211. The limiting plate 217 is provided with a through hole for the piston rod 280 to pass through, one end of the piston rod 280 passes through the through hole and then is coaxially and threadedly connected with the first piston 213, and one end of the piston rod 280 far away from the first piston 213 is universally connected with the loop bar 310 through the spherical connecting piece 220.

The housing 212 is integrally molded on the outside of the cylinder block 211, and a second oil chamber 240 is formed between the housing 212 and the cylinder block 211. The second piston 214 is inserted into the second oil chamber 240, and the inner circumferential surface of the second piston 214 abuts against the outer circumferential surface of the cylinder block 211, and the outer circumferential end of the second piston 214 abuts against the inner circumferential surface of the housing 212.

When the triangular bracket is used, a surveying and mapping staff firstly unfolds the supporting leg 300, when the supporting leg 300 is unfolded, the supporting leg 300 drives the piston rod 280, the piston rod 280 drives the first piston 213 to move towards the limiting plate 217, and hydraulic oil in the first oil cavity 230 slowly flows to the second oil cavity through the oil through hole 215; then, the big head screw 218 is rotated, so that one end of the big head screw 218, which is far away from the bolt head of the big head screw, extends into the oil through hole 215, and further plugs the oil through hole 215, so that the length of the connecting mechanism 200 can not be adjusted temporarily, the holder 100 can be kept stable, and at the moment, the surveying and mapping tool is installed on the platform to begin surveying and mapping.

When the weight of the surveying and mapping tool is large, the length of the connecting mechanism 200 cannot be adjusted temporarily, so that the tripod is not easy to slide relative to the ground, the probability of toppling of the triangular support is reduced, and a surveying and mapping instrument is further effectively protected; even if the oil through hole 215 is not closed by the tapered surface of the big head screw 218 to cause oil leakage, the height of the holder 100 is not easily suddenly reduced due to the damping effect generated by the oil through hole 215, and further the probability of damage of the surveying and mapping instrument is reduced.

When the surveying and mapping personnel finish surveying and mapping work, the triangular support is required to be collected, firstly, the surveying and mapping instrument is taken down from the triangular support, then the big head screw 218 is rotated to enable one end, away from the bolt head, of the big head screw 218 to be away from the oil through hole 215, the oil through hole 215 is enabled to keep smooth flowing of hydraulic oil, the big head screw 218 is rotated after the supporting leg 300 is contracted, one end, away from the bolt head, of the big head screw 218 extends into the oil through hole 215, the oil through hole 215 is blocked, the piston rod 280 cannot move any more, and finally the sliding rod 320 slides into the sliding groove in the sleeve rod 310.

When the amount of the hydraulic oil in the first oil chamber 230 and the second oil chamber 240 is insufficient, the hydraulic oil is added to the damping assembly 210 through the oil filling hole, at this time, the big head screw 218 needs to be rotated, so that the tapered surface of the big head screw 218 is far away from the oil through hole 215, at this time, the hydraulic oil in the second oil chamber 240 flows to the first oil chamber 230 through the oil through hole 215, and when the hydraulic oil is filled, the big head screw 218 is rotated to enable the tapered surface to abut against the oil through hole 215.

The implementation principle of the triangular support of the invention is as follows:

when the tripod is used, the sliding rod 320 is slid to a required length, and then the supporting legs 300 are spread, so that the supporting legs 300 form a tapered structure to stably support the tripod head 100. Firstly, a surveying staff unfolds the supporting leg 300, when the supporting leg 300 is unfolded, the supporting leg 300 drives the piston rod 280, the piston rod 280 drives the first piston 213 to move towards the limiting plate 217, and hydraulic oil in the first oil chamber 230 slowly flows to the second oil chamber through the oil through hole 215; then, the big head screw 218 is rotated, so that one end of the big head screw 218, which is far away from the bolt head of the big head screw, extends into the oil through hole 215, and the oil through hole 215 is blocked, so that the length of the connecting mechanism 200 cannot be adjusted temporarily, the holder 100 can be kept stable, and at the moment, the surveying and mapping tool is installed on the platform to begin surveying and mapping.

When the weight of the surveying and mapping tool is large, the length of the connecting mechanism 200 cannot be adjusted temporarily, so that the tripod is not easy to slide relative to the ground, the probability of toppling of the triangular support is reduced, and a surveying and mapping instrument is further effectively protected; even though oil through hole 215 is not closed by the conical surface of thumb screw 218 and is caused the oil leak, because the damping action that oil through hole 215 produced, the height of cloud platform 100 is difficult suddenly to reduce, and then has reduced surveying instrument's probability of damaging.

The above are all preferred embodiments of the present invention, and the protection scope of the present invention is not limited thereby, so: all equivalent changes made according to the structure, shape and principle of the invention are covered by the protection scope of the invention.
