Title:
CLAMPING FORCE-VISIBLE DEVICE AND CLAMP
Document Type and Number:
WIPO Patent Application WO/2020/143453
Kind Code:
A1
Abstract:
A clamping force-visible device, comprising a first clamping body (01) for clamping an object. The first clamping body (01) is telescopically mounted on a base (14). Elastic elements (110) are provided between the first clamping body (01) and the base (14). The first clamping body (01) and the base (14) are respectively provided with a clamping force scale (11) and a reading indicator (15). When the first clamping body (01) clamps an object, the elastic elements (110) measure the clamping force and point to the clamping force scale (11) by means of the reading indicator (15) to implement reading, such that the size of the clamping force can be intuitively seen and read during clamping to implement accurate clamping. The present invention also relates to a clamp comprising the clamping force-visible device.
