US Patent 10161563 Stand clamp with ease of force application

The stand clamp with ease of force application comprises a fixed part, a movable part and a screwing-lock part. The movable part is pivotally coupled to the fixed part. The screwing-lock part includes a bolt, a pressing plate, a rotating rod and a resetting assembly, wherein two ends of the bolt are provided with a threaded section and a ratchet wheel section respectively. Further, the rotating rod slips with respect to the bolt to form a reset position and an actuating position. The resetting assembly is linked to the bolt and the rotating rod, such that the rotating rod is in the reset position under an ordinary state. In addition, the rotating rod can freely rotate with respect to the bolt at the actuating position. Therefore, an operator can freely change the position of the rotating rod and apply a force with a most suitable application angle.
