Meanwhile, in order to fix the bushing a516, that is, in order to fix the gear ring a514 rotated in place, in this embodiment, a locking knob a517 is further sleeved on the lower vertical section below the bushing a516, as shown in fig. 13, the locking knob a517 is in a bottle cap-shaped structure, and a cap bottom of the locking knob a517 is sleeved on the lower vertical section in a threaded manner, and when screwed upwards, the bushing a516 can be covered and axially pressed against the bushing a516 so as to be fixed. When the inner wall thickness measuring device 4 provided by the embodiment is used, the gear ring a514 is held to rotate like a steering wheel, the gear ring a514 drives the cylindrical driven gear a513 to rotate, so that the threaded pipe a511 is driven to rotate, the threaded pipe a511 enters/extends out of the upper vertical section a512 of the first connecting rod, on one hand, fine adjustment of height is performed, on the other hand, the measuring device 4 can be fixed at any time after rotating in place along with the threaded pipe a511, the gear ring a514 can be fixed after the locking knob a517 is screwed, namely, the threaded pipe a511 is fixed, and the measuring device 4 cannot rotate any more and cannot move up and down. And choose to adopt cylindrical driven gear a513, adopt a shaft-like gear structure in fact, only need to adopt the gear ring a514 that thickness is very thin like this, when rotating, although screwed pipe a511 (driven gear a513) is moving axially constantly, still can keep the contact with gear ring a514, the two can not break away from the engaged state, it is very ingenious and practical structurally. The working part a100 better realizes the installation of the measuring device 4 on the workbench 2, for example, during the actual manufacturing, the aforementioned supporting plate a1 can be fixedly connected with the workbench 2, and a plug part a7 can be fixedly connected to the bottom of the supporting plate a1 for being fixedly connected to the upper surface of the workbench 2; the top of the second connecting rod a52 can be directly fixed with the measuring scale 41, or the top of the second connecting rod a52 is provided with a connecting body a6 to fix the bottom of the measuring device 4, and the invention can be designed adaptively.

In the description of the present invention, it is to be understood that the terms "length", "width", "upper", "lower", "front", "rear", "left", "right", "vertical", "horizontal", "top", "bottom", "inner", "outer", and the like, indicate orientations or positional relationships based on the orientations or positional relationships illustrated in the drawings, and are used merely for convenience in describing the present invention and for simplicity in description, and do not indicate or imply that the devices or elements referred to must have a particular orientation, be constructed in a particular orientation, and be operated, and thus, are not to be construed as limiting the present invention. Further, in the description of the present invention, "a plurality" means two or more unless specifically defined otherwise.

While the invention has been described with reference to a preferred embodiment, it will be understood by those skilled in the art that various changes in form and detail may be made therein without departing from the spirit and scope of the invention as defined by the appended claims.
