[0031] It should be noted that, in this embodiment, the upper pressure equalizing plate 2, the lower pressure equalizing plate 4 and the dynamometer 3 are all set to be circular. In other embodiments, the dynamometer 3 can also be set to be square, rectangular or other shapes, and its shape is not specifically limited here.

[0032] Specifically, the dynamometer box 1 includes a main body 11 and an extension portion 12 connected to the main body 11 . The extension portion 12 extends inward from an inner wall of the main body 11 .
