Abstract
The invention relates to a clamping device preventing adjusting screws from falling. The clamping device comprises a first clamper and a second clamper. The first clamper comprises a first handle and a first grip jaw, both of which are fixedly connected. The first handle is provided with an internal thread portion in the manner of extending along the axial direction of a virtual penetration axis. The first handle is provided with a sliding section and an adjusting part. The adjusting part is arranged in the internal thread part in a threaded mode along an axial direction of the virtual penetration axis. One end of the adjusting part is provided with an anti-falling portion and extends to the sliding section. The distance between the top and the axis center of the anti-falling portion is larger than or equal to the hole diameter of the internal thread portion. The second clamper is connected to the first clamper and further comprises a fastening part, one end of which is slidably arranged at the sliding section of the first handle and abuts against the adjusting part. The adjusting part cannot separate from the first handle due to the anti-falling portion in order to prevent the adjusting part from overly rotating and falling down.
