A safety clamping jaw includes at least one lever arm, a wedge member provided on a first end of each lever arm, a roller provided on a second end of each lever arm, a cam member provided between the rollers, and a resilient member bearing against the cam member. Upon activation of the clamping jaw, each roller may push the cam member in a direction towards the resilient member, thereby compressing the resilient member. |
