The purpose of providing the support plate 118 is to facilitate forming a planar four-bar mechanism between the two support legs 102, the support base 101 and the support plate 118. In this way, when one support leg 102 is rotated, the rotation of the other support leg 102 can be completed. When the support leg 102 rotates, the lock buckle 103 connected to the support leg 102 rotates together with the support leg 102 until the lock buckle 103 rotates to the inside of the lock plate 104, the lock buckle 103 squeezes the locking rod 119, and the locking rod 119 squeezes the elastic member until the lock buckle When 103 is fully rotated to the inside of the locking plate 104, the elastic member is specifically the first spring 105. The reaction force of the first spring 105 acts on the locking rod 119 and then acts on the lock buckle 103. The locking rod 119 fixes the position of the lock buckle 103, thereby completing the locking of the support leg 102, and finally completing the installation of the unmanned helicopter tripod; when storing, it is only necessary to rotate the support legs 102 on both sides of the support seat 101 in the opposite direction again. The lock buckle 103 squeezes the locking rod 119 and the first spring 105 under the action of external force, and the lock buckle 103 is rotated out of the locking plate 104 to complete the storage of the unmanned helicopter tripod. The advantage of this arrangement is that the support leg 102 can be well installed and stored through the locking assembly, the operation is simple, and the cost is low.

[0032] In some embodiments, the locking plate 104 is a U-shaped structure, the end surface of the locking plate 104 is fixedly connected to the side wall of the support base 101 , and the locking buckle 103 is used to follow the support leg 102 and screw into the locking plate 104 .
