When in use, referring to fig. 6, the lower end surface of the travel sleeve 1 is abutted against the angle measuring hole 101 at the preset position of the bone plate 10 to be measured, the push rod 2 is driven to move downwards, and when the lower end of the push rod 2 (which can be directly used as a measuring probe) is abutted against the bone surface 20 corresponding to the bone plate 10 to be measured, the scale 21 indicated by the scale line is read, namely the bone plate attaching angle alpha (namely the tilting angle of the bone plate 10 to be measured).
The angle measurement principle is as follows: the angle measuring hole 101 is located at a preset position, and the distance between the preset position and the attachment point of the bone plate 10 and the bone surface 20 (i.e., the vertex of the bone plate attachment angle α) is a preset known distance; the lower end of the push rod 2 is provided with a measuring probe, and the included angle between the measuring probe and the bone plate 10 is known; the extension distance of the measurement probe is known (the thickness of the bone plate 10 can be reduced in advance); in the plane coordinate system, the bone plate attaching angle alpha can be calculated by using a conventional mathematical formula. The angle measurement range can be flexibly designed according to the needs, and can be 0-30 degrees for example.
The bone plate attaching angle measuring device comprises a travel sleeve and a push rod which is arranged in the travel sleeve and can move up and down, wherein the lower end face of the travel sleeve is used for abutting against the upper surface of a bone plate to be measured, the lower end of the push rod is used for abutting against the corresponding bone surface of the bone plate to be measured, one of the travel sleeve and the push rod is provided with scales for displaying the attaching angle of the bone plate, and the other one of the travel sleeve and the push rod is provided with scales for reading the scales, so that the attaching angle of the bone plate and the bone surface can be measured.

To increase the contact area of the lower end of the travel sleeve 1 with the bone plate 10 to be measured (i.e. the lower end cross-sectional area of the row Cheng Taotong 1), and further improve the stability during measurement, the lower end of the travel sleeve 1 is preferably a flat abutment 11, and the probe rail 111 is located on the abutment 11. The shape of the abutment 11 can be flexibly set as required, however, in order to make the overall structure attractive, the shape of the abutment 11 may be square in side view and may be oblate in cross section.
In order to facilitate the driving connection of the lower end of the push rod 2 to the measuring probe 3, various structural forms which can be easily thought by a person skilled in the art can be adopted, for example, the lower end of the push rod 2 pushes the measuring probe 3 through a transverse push rod; however, in order to improve the fault tolerance of the probe during measurement and prevent the phenomenon of jamming during measurement, the invention preferably adopts the following structural form:

The measuring probe is designed to be arc-shaped, and the distance of the arc-shaped measuring probe extending out is converted into the stroke of the push rod by utilizing the structural principle of the cam roller, so that the numerical reading is visual and simple.
The angle measuring hole 101 is located at a preset position, and may be implemented by adopting a mode that the end of the angle measuring hole 101 away from the bone plate 10 (the end is regarded as a joint point between the bone plate 10 and the bone surface 20 at this time) is a preset distance, or adopting a mode that a bending part of the angle measuring hole 101 away from the bone plate 10 (the bending part is usually provided with a bending groove and is easy to identify; the bending part is regarded as a joint point between the bone plate 10 and the bone surface 20 at this time, namely, a black point on the left side of fig. 6) is a preset distance L.
