AI Technical Summary
Technical Problem
Existing dual-arm support structures are relatively complex and costly, making it difficult to achieve flexible and economical synchronous adjustment.
Method used
The first and second arms employ a two-bar linkage structure. A pre-tension spring is installed in one of the arms, which, in conjunction with a linkage rod, enables synchronous adjustment. The linkage rod slides or rolls in a groove to transmit the pre-tension force and maintain the arm in a suspended position.
Benefits of technology
It achieves synchronous adjustment with simple structure and low cost, keeps the equipment vertical on the same plane when adjusting height, allows relative rotation adjustment of the two arms, and meets flexible adjustment of orientation.

Abstract
The utility model relates to a synchronous adjusting double arm and a support. The synchronous adjusting double arm comprises a first section arm and a second section arm which are of four-bar linkage structures, and a pre-tightening spring is arranged in one arm to maintain the hovering position of the arm; wherein the end parts of the first section arm and the second section arm are connected through a shaft, the first section arm and the second section arm can rotate relatively to adjust the direction, a linkage rod is arranged at the axial lead in a penetrating manner, two ends of the linkage rod respectively slide or roll to abut against chutes on the far sides of the first section arm and the second section arm to realize double-arm linkage, and the two arms are far away from the shaft connecting end. And a suspension assembly and a base assembly are respectively arranged to form a complete bracket. The device has the characteristics of unique conception, simple structure and flexibility in adjustment and operation; especially, the two arms are of a four-connecting-rod structure, only one pre-tightening spring is arranged, synchronous adjustment is achieved through a linkage rod, during height adjustment, the hanging equipment can be kept on the same vertical plane, the two arms are allowed to rotate relatively, and adjustment of the orientation is met.
