[Technical field]

[0001] The utility model relates to the technical field of measuring devices, in particular to the technical field of M value measuring instrument transmission devices. [Background technology]

[0002] In the prior art, the measurement of the M value of an internal gear requires a specific measuring rod to be fixed in the tooth groove, and then an internal micrometer is used to measure left and right, up and down, and the minimum value is the actual part M value. However, during the measurement process, the M value measured by personal feel has a certain error, especially when measuring the M value in a narrow space that is not convenient for measurement, the fixed end of the internal micrometer is not easy to measure the highest point of the measuring rod, which easily causes the measurement deviation to increase. [Utility Model Content]

[0005] Preferably, a limiting sliding groove is provided on the inner side surface of the branch elastic foot corresponding to the position of the transmission rod, and the transmission rod is in sliding contact with the limiting sliding groove.

[0006] Preferably, a thickened mounting block is provided at the end of the branch elastic foot, and the measuring rod is detachably arranged on the thickened mounting block.

[0007] Preferably, the transmission rod is a smooth cylindrical straight rod, and a pointed head is provided at the bottom end of the transmission rod.

[0008] Preferably, the branch elastic feet and the measuring rod are arranged perpendicular to each other.

[0009] Preferably, there are multiple measuring rods, and the measuring rods are symmetrically arranged front to back.

[0010] Preferably, the diameter of the rolling steel ball is smaller than the bottom width of the groove of the inner teeth of the gear being measured.
