Set up like this, can drop the type nut through the second and make the locking plate reciprocate along locking screw to fix the cable fast, simultaneously, overall structure is simple, and the test is convenient.

Further, a top cover used for sealing the supporting column is arranged on the top plate. The arrangement of the top cover can prevent dust from entering.

Wherein, bottom plate, support column, roof, lifting screw, removal support, clamping screw, clamp plate, first butterfly nut, clamp plate, locking screw, locking plate, second butterfly nut, top cap etc. all adopt SUS304 material to support in this application, guarantee structural strength and life.

Has the beneficial effects that: during the use, place the product that awaits measuring on clamping mechanism fixed to pass through locking mechanism with its cable fixed, utilize elevating system to drive the product that awaits measuring and reciprocate, cooperate the tensile cable of locking mechanism, thereby carry out the atress test to the cable, and feed back the numerical value of gathering to display module through the dynamics probe. The device of this application, overall structure is simple, can be quick test the product that awaits measuring, and the measurement accuracy is high simultaneously, punctual demonstration result simultaneously. The mode that adopts lift screw and servo motor that sets up like this, device lifting precision is high, and lifting precision can reach 0.01mm, and the dynamics precision is high, and the dynamics precision can reach 0.01N, lets the test result more accurate.
