摘要： A support anti-breaking structure includes a first plate member (1), a second plate member (2) and a first fixing member (3). An end of the first plate member (1) is pivotally connected to an end of the second plate member (2) at a first pivotal connection (S1). The first fixing member (3) is formed by a flexible structure and fixed to a side of the first pivotal connection (S1). The first plate member (1) and the second plate member (2) can press the first fixing member (3), so that the first plate member (1) and the second plate member (2) can be rotatably folded. When the first plate member (1) rotates relative to the second plate member (2) in a direction of pulling the first fixing member (3), the first fixing member (3) will exert reaction force to the first plate member (1) and the second plate member (2) by structural strength itself, thereby restraining the rotation of the first plate member (1) relative to the second plate member (2), so as to effectively reduce the probability of breaking the first pivotal connection (S1) due to incorrect operation of the rotation and folding.
