Abstract

The present invention discloses a bracket crimping device, comprising a control component, a plurality of adjustment components arranged on the control component, and a plurality of crimping components respectively connected to the corresponding adjustment components. The present invention reduces the assembly accuracy of the bracket crimping device through the arrangement of the adjustment components, is compatible with lower processing accuracy, has better stability, and thus reduces research and development costs. Specifically, the crimping block is deflected to an appropriate angle by adjusting the length of the adjustment rod to avoid jamming of the plurality of crimping blocks when rotating. At the same time, the elastic connecting piece is adjusted to make each crimping block subject to the same locking force to avoid jamming during reverse rotation.
