around the outer wall of the metal ring, whether the outer surface of the sampled metal ring has the concave and convex states can be rapidly judged, so as to rapidly judge whether the sampled metal ring meets the production and use requirements, the middle part of the front end face of the detection rod 23 is provided with a smooth convex shape, so that friction is greatly reduced when the detection rod 23 is contacted with the outer wall of the metal ring, and the sampled outer wall of the metal ring is not damaged, the whole detection main body 20 can be taken out from the inside of the first limit outer frame 29 and the second limit outer frame 37 after the sealing plate fixedly installed on the front end of the first limit outer frame 29 through threads is taken down, so that the detection pen 22 can be replaced by screwing the fastening bolt 27, the front end of the adjusting bolt 35 can move in the threaded jack arranged at the bottom of the first limit outer frame 29 through screwing the adjusting bolt 35 after the paper sheet is inserted into the slot 36 before detection, so that the spring 33 can be extruded between the first limit outer frame 29 and the second limit outer frame 37 to be closed, and the front end of the detection pen 22 can be contacted with the middle part of the paper sheet, thereby the line body drawn by the detection pen 22 can be left on the device detection observation paper sheet, the supporting buffer spring 6 arranged between the supporting block 5 and the supporting frame 8 can prevent the supporting frame 8, the supporting plate 11 and the limiting groove hole 12 from rapidly descending when the extrusion pressure of the fastening threaded rod 7 to the inside of the fastening groove 9 is insufficient, the buffer function is achieved, thereby effectively preventing the possibility of contact collision between the detection mechanism 1 and the upper end surface of the supporting base 4, effectively protecting the device, and the device can be designed into different specifications and sizes according to the specification of the metal ring to be detected, thereby realizing the rapid and accurate detection of metal ring samples with different types, the invention can rapidly detect the outer wall of the sampled metal ring in the using process, whether the outer wall that can accurate detection go out metal ring has sunken and protruding to the testing result is convenient for audio-visual observation.

Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that changes, modifications, substitutions and alterations can be made in these embodiments without departing from the principles and spirit of the invention, the scope of which is defined in the appended claims and their equivalents.
