In the measurement process, in order to ensure that the probe 200 does not slide out of the sleeve body 110, the limiting mechanism may be used to limit the probe 200, so that the measurement work can be performed normally. After the measurement is completed, the user only needs to slightly increase the acting force of the push plate 230 towards the rear end 112 of the sleeve body 110, so that the protrusion 221 is compressed towards the retraction spring 223 in the accommodating groove 222, and the protrusion 221 is allowed to retract into the accommodating groove 222 under the driving of the retraction spring 223, so that the probe 200 can slide out of the sleeve body 110 smoothly.
Referring to fig. 1, the end of the push plate 230 near the front end 111 of the sleeve body 110 has a slant structure. By setting the front end 111 of the push plate 230 to be an inclined plane structure, it is more beneficial for a user to accurately read the scale value corresponding to the front end 111 of the push plate 230 in the measurement process.
Fig. 7 is a schematic view of the split type high-precision measuring scale shown in fig. 2 in a measurement initial state. Referring to fig. 7, when one end of the push piece 230 near the front end 111 of the sleeve body 110 is located at the head end of the scale 130, one end of the measuring rod 210 far from the slider 220 is flush with the end of the thin sleeve 120. Therefore, the accuracy of the measuring ruler can be ensured to be kept at a higher level, and errors caused by the measuring ruler are avoided.
Fig. 6 is an enlarged schematic view of the portion B in fig. 4. Referring to fig. 6, an end of the measuring rod 210 remote from the slider 220 is provided with a positioning hook 211. In the measuring process, the measuring rod 210 extends out of the end part of the thin sleeve 120 and extends into the bone hole to be measured, one end part of the rod 210 to be measured far away from the sliding block 220 is propped against the surface of the bone hole, which is far away from the surface of the bone hole, and the back of the bone hole can be hooked by the positioning hook 211, so that the measuring ruler can be positioned accurately, and the reading is convenient and quick.
The above embodiments are not intended to limit the scope of the present utility model, so: all equivalent changes in structure, shape and principle of the utility model should be covered in the scope of protection of the utility model.
