Detailed Description

The following description of the embodiments of the present invention will be made in detail with reference to the accompanying drawings.

In the description of the present invention, it should be noted that the terms "upper", "lower", "front", "rear", "left", "right", "vertical", "inner", "outer", etc., indicate orientations or positional relationships based on the orientations or positional relationships shown in the drawings, and are only for convenience of description and simplicity of description, but do not indicate or imply that the device or element being referred to must have a particular orientation, be constructed and operated in a particular orientation, and thus, should not be construed as limiting the present invention.

The measuring caliper comprises a caliper body 1, wherein a jaw 2 is arranged on the caliper body 1, the jaw 2 comprises a fixed jaw and a movable jaw, an inner gear jaw 3 is detachably connected to the fixed jaw and the movable jaw, and the inner gear jaw 3 is of an L-shaped structure. The two claws are provided with the corresponding inner-gear claws 3, and the L-shaped inner-gear claws 3 extend into the roller, so that the inner-gear size of the roller can be conveniently measured; can dismantle in order using as conventional slide caliper rule with shelves jack catch in the normal use, under the condition that does not change original slide caliper rule structure, the setting through shelves jack catch in the L type has further improved slide caliper rule's suitability, simple structure, and is with low costs.

In the utility model, the inner gear claw 3 comprises a vertical extension section 31 connected to the claw 2, and the lower end of the vertical extension section 31 is provided with a horizontal extension section 32 extending inwards. The vertical extension section 31 is convenient to install and measure the inner gear, and the horizontal extension section 32 can go deep into the roller to measure. The fixed jaw and the inner gear jaw 3 on the movable jaw are oppositely arranged to form a frame-returning structure shown in figure 2, and the end parts of the horizontal extension sections 32 of the inner gear jaws 3 are opposite to realize accurate measurement.

In the utility model, an installation clamping groove 34 is arranged on one side wall of the vertical extension section 31 opposite to the horizontal extension section 32, and the installation clamping groove 34 is clamped and installed on the clamping jaw 2. The mounting slot 34 extends from the upper end to the lower end of the vertical extension 31. The side wall of the vertical extension section 31 is provided with a plurality of mounting holes 33 which are arranged at intervals, and the fastening screws 4 are screwed and positioned opposite to the surfaces of the clamping jaws 2 through the mounting holes 33.
