Automobile calibration device

Abstract

The present invention relates to the field of automobile maintenance and device calibration technologies, and discloses a clamping apparatus and an automobile calibration device. The clamping apparatus includes a fixing plate, a fixing block and a tension knob. The fixing block includes a fixing block body and a locking spring piece. The fixing block body is installed on the fixing plate. A receiving cavity is enclosed by the fixing block body and the fixing plate. The locking spring piece is located in the receiving cavity. The tension knob is installed on the fixing block body. The tension knob is capable of rotating relative to the fixing block body, to extend inside the receiving cavity and to abut against the locking spring piece. When a to-be clamped and calibrated apparatus is inserted in the receiving cavity, the tension knob may push the locking spring piece to abut against the to-be clamped and calibrated apparatus. Because the locking spring piece is in surface contact with the to-be clamped and calibrated apparatus, a friction between the locking spring piece and the to-be clamped and calibrated apparatus increases, so that the locking spring piece may firmly abut against the to-be clamped and calibrated apparatus.
