Copper binding wire tension tester with good fixing effect

Abstract

The invention provides a copper binding wire tension tester with the good fixing effect. The tester comprises a longitudinal installation frame, a Velcro buckle, an adjustable movable fixing frame structure, a copper binding wire clamping fastening seat structure, a lead screw, a longitudinal U-shaped sliding groove, a sliding block, a connection frame with an internal thread, a tension sensor, atransverse fixing plate, a longitudinal positioning pipe, a manual rotary frame structure, a ball bearing, a displaying screen and a miniature PLC, wherein the Velcro buckle is transversely adhered tothe outer sides of the lower parts of the longitudinal installation frame and the transverse fixing plate. Arrangement of a reinforcing limiting block and a jacking spacer block is beneficial for utilizing a jacking bolt to jack a copper binding wire between the jacking spacer block and the reinforcing limiting block, and accordingly the clamping and fixing degree of the copper binding wire can be improved; and arrangement of the transverse connection rod, the transverse positioning pipe and a rocking handle is beneficial for adjusting the length of the left end or the right end of the transverse connection rod conveniently, and accordingly the labor intensity of rotating the rocking handle can be saved when the length of the left side is increased.

Description
