Common tensiometers include mechanical and electronic types.

[0003] In modern material testing and engineering applications, as an important measuring tool, the accuracy of a tensiometer directly affects the quality evaluation and performance analysis of products. However, many existing tensiometer measuring tools face serious problems during the calibration process, among which the most prominent are the phenomenon of the tension hook becoming unhooked and insufficient calibration accuracy. Content of the Utility Model

[0004] The purpose of the utility model is to provide a calibration tool for tensiometer measuring instruments to solve the problems raised in the above background technique.

[0005] To achieve the above purpose, the utility model provides the following technical solutions:

A first sliding groove is opened at the bottom of the fixing seat.

[0012] Preferably, the butting seat is slidably connected inside the first sliding groove. The second threaded rod is threadedly connected to the fixing seat. The butting seat is inserted into the inside of the first sliding groove.

[0013] Preferably, a measuring mechanism is arranged on the inner side wall of the mounting seat, and a hook mechanism is installed at one end of the first threaded rod.

[0014] Preferably, the measuring mechanism includes a measuring plate, a scale groove, and a second sliding groove. The measuring plate is fixedly connected to the inner side wall of the mounting seat. A scale groove is provided on the outer part of the measuring plate, and a second sliding groove is formed on the inner side wall of the measuring plate.

[0015] Preferably, a threaded movable plate is inserted into the second sliding groove, and the threaded movable plate is slidably connected inside the second sliding groove.

[0016] Preferably, the hook mechanism includes a fixed block, an insertion seat, and a hanging hook. The fixed block is rotatably connected to the outer side wall of the first threaded rod.
