Clamping head

The utility model relates to a clamping head which comprises a first clamping head and a second clamping head rotatably connected with the first clamping head, the first clamping head is provided with a clamping cavity capable of containing a piece to be installed, and a connecting piece capable of synchronously rotating along with the second clamping head and reciprocating in the axial direction of the second clamping head is arranged in the second clamping head. The periphery of the connecting piece is polygonal, one end of the connecting piece extends into the clamping cavity, and the other end of the connecting piece is connected with an elastic telescopic piece. The clamping head has the advantages that the clamping head is provided, and the problems that in the prior art, the requirement for machining precision is high, and the clamping head cannot adapt to the assembling environment with the more stable requirement for the connecting state are solved. 本实用新型涉及一种装夹头，包括第一夹头及与第一夹头可转动连接的第二夹头，所述第一夹头上设有可容纳待装件
