[0025] The technical scheme in the embodiments of the present application will be described clearly and completely below. Obviously, the described embodiments are only some of the embodiments of the present application, but not all the embodiments. Based on the embodiments in the present application, all other embodiments obtained by those skilled in the art without creative labor are within the scope of protection of the present application.

[0026] Please refer to Figs. 1-3 , the embodiments of the present application include:

[0027] A depth detector for orthopedics, which comprises: a measuring cap 1, a measuring rod 2, a measuring sleeve 3, a connecting block 4, a copper ball 5, a vertical connecting groove 6, a horizontal connecting groove 7, a guide groove 8, a spring 9, and a indicating rod 10.

[0028] A measuring channel 11 and a mounting groove 12 are axially arranged in the measuring cap 1 from front to back, the front end of the measuring sleeve 3 is connected with the mounting groove 12 to complete the connection of the measuring cap 1 and the measuring sleeve 3, and the measuring channel 11 is connected with an active cavity 31 in the measuring sleeve 3 through the mounting groove 12, the front part of the indicating rod 10 is movably arranged in the active cavity 31, the measuring rod 2 is movably connected with the measuring channel 11, the front end thereof is connected with a probe 21 outside the measuring cap 1, the rear end thereof extends into the active cavity 31 through the mounting groove 12, and the rear end is connected with the front end of the indicating rod 10 through the connecting block 4, so that the measuring rod 2 and the probe 21 move forward and backward under the pushing and pulling action of the indicating rod 10 to perform measurement.

[0029] Further preferably, an anti-skid pattern 13 is arranged on the outer peripheral wall of the measuring cap 1 close to the measuring sleeve 3.

[0030] Further preferably, the measuring rod 2 is integrated with the probe 21.

[0031] Further preferably, the rear end of the measuring sleeve 3 is provided with an inwardly retracted limiting part 32 which is integrated with the measuring sleeve, and the indicating rod is provided with a protrusion which cooperates with the limiting part to prevent the indicating rod from being pulled out of the rear end of the measuring sleeve.

[0032] The top and / or bottom of the front part of the indicating rod 10 is provided with a vertical connecting groove 6, and one or both sides of the front part of the indicating rod 10 is provided with a horizontal connecting groove 7. The copper ball 5 is elastically arranged in the vertical connecting groove 6 and the horizontal connecting groove 7 by the spring 9, and a part of the copper ball 5 protrudes from the outer periphery of the indicating rod 10, and the protruding part is less than 1 / 3 of the whole copper ball 5, so as to form a self-adapting displacement limiting assembly.
