The invention discloses a clamping device for fixing a support. The clamping device comprises an inner rotating piece, an outer rotating piece, a first linkage structure, a second linkage structure and a fastening connecting piece used for connecting and fixing the support. A first through hole is formed in the inner rotating piece, the fastening connecting piece is provided with the inner rotating piece through the first through hole, the inner rotating piece is in threaded connection with the fastening connecting piece, a second through hole is formed in the outer rotating piece, and the inner rotating piece is provided with the outer rotating piece through the second through hole; and the first linkage structure is connected to the inner rotating piece, the second linkage structure is connected to the outer rotating piece, and the first linkage structure makes contact with the second linkage structure. When the outer rotating piece is rotated, the outer rotating piece can drive theinner rotating piece to rotate synchronously through a first acting force generated between the first linkage structure and the second linkage structure, and when a second acting force for rotating the outer rotating piece is larger than the first acting force, the outer rotating piece and the inner rotating piece move relatively. The fastening connecting piece can be prevented from being damaged.
一种用于固定支架的夹持装置,包括内旋转件、外旋转件、第一联动结构、第二联动结构及用于连接并固定支架的紧固连接件,内旋转件上设有第一通孔,内旋转件通过第一通孔套置在紧固连接件上,内旋转件与紧固连接件螺纹连接,外旋转件上设有第二通孔,外旋转件通过第二通孔套置在内旋转件上;第一联动结构连接在内旋转件上,第二联动结构连接在外旋转件上,第一联动结构与第二联动结构接触;当转动外旋转件时,外旋转件可通过第一联动结构和第二联动结构之间产生的第一作用力带动内旋转件同步转动,当转动外旋转件的第二作用力大于第一作用力时,外旋转件与内旋转件发生相对移动。其能避免紧固连接件损坏。
