A threaded column 10 capable of being inserted into the inside of the stop groove 7 is provided at the position corresponding to the positioning groove 8 on the side wall of the diagnostic instrument body 1, and a force disk 9 is provided on the end of the threaded column 10 away from the positioning groove 8, which is placed on the side wall of the diagnostic instrument body 1. This design applies force to the cover plate 4 so that the bottom of the cover plate 4 rotates under the action of the rotating hinge 3 and fits with the top of the diagnostic instrument body 1, while positioning The column 6 is guided and moved along the positioning groove 8 to fit into the positioning groove 8, and then force is applied to the force disk 9 to drive the threaded column 10 to rotate and insert into the stop groove 7 of the positioning column 6 to stop the positioning column 6, thereby avoiding looseness between the diagnostic instrument body 1 and the cover 4, making it easier to close the cover 4 and improving the stability of holding. When the cover 4 needs to be opened, it is only necessary to rotate the force disk 9 in the opposite direction to drive the threaded column 10 out of the stop groove 7, and then apply force to the cover 4 to open the cover 4, thereby making it easier to open the cover 4 and enhancing the opening and closing effect of the cover 4.

[0026] Reference Figure 1 、 Figure 2 and Figure 3 When the top of the diagnostic instrument body 1 contacts the bottom of the cover 4 , the retaining groove 7 corresponds to the threaded column 10 . This design facilitates the insertion of the threaded column 10 into the retaining groove 7 .

[0027] Reference Figure 4 and Figure 5The side wall of the diagnostic instrument body 1 is provided with a threaded hole 11 connected to the positioning groove 8, and the threaded column 10 matches the threaded hole 11. This design facilitates the threaded column 10 to move laterally along the threaded hole 11 and insert into the retaining groove 7.
