The first embodiment is as follows:

referring to fig. 1, an inside and outside groove caliper gauge comprises a dial 1 and two first swing arms 21, one ends of which are hinged to each other through first joint locking nuts 61, wherein a pointer 3 for indicating scales on the dial 1 is fixedly connected to the end part of each first swing arm 21 close to the first joint locking nut 61, the dial 1 is fixedly sleeved on the first joint locking nuts 61, and when the two first swing arms 21 rotate around the first joint locking nuts 61, the pointer 3 rotates on the dial 1; the other end of each first swing arm 21 is hinged with one end of a second swing arm 22 through a second joint locking nut 62, the other end of each second swing arm 22 is hinged with a probe 4 provided with a probe 5 through a third joint locking nut 63, and the two probes 5 are detachably mounted on the probe 4; scales which take the hinge holes as the circle centers are carved at the two ends of each second swing arm 22, and scribed lines for indicating the scale reading are carved on the first swing arm 21 and the probe 4; spring pads are arranged below the first joint locking nut 61, the second joint locking nut 62 and the third joint locking nut 63, and when the nuts are loosened, certain friction force is generated among all the parts connected through the nuts, so that natural loosening is not generated among all the parts.

When the groove arranged on the outer surface of the part is measured, firstly, a first joint locking nut 61, a second joint locking nut 62 and a third joint locking nut 63 are loosened, the part to be measured is placed inside a caliper, the directions of two probes 5 are adjusted, the two probes 5 are in a horizontal state, the needle points of the probes 5 point inwards to an object to be measured, the third joint locking nut 63 is locked, the reading of the scribed lines on each probe 4 on a dial corresponding to the probe is respectively recorded, then, the first swing arm 21 and the second swing arm 22 are adjusted, the probes 5 are tightly pressed against the outer wall of the object to be measured, the first joint locking nut 61 and the second joint locking nut 62 are locked, the reading of two pointers 3 on the dial 1 and the reading of the scribed lines of each first swing arm 21 on the dial at the hinged part of the second swing arm 22 and the first swing arm 21 are respectively recorded, then, the first joint locking nut 61 and the second joint locking nut 62 are loosened, taking out the caliper gauge, placing the caliper gauge on a horizontal table surface, adjusting the first swing arm 21 and the second swing arm 22, respectively adjusting the reading of the two pointers 3 on the dial plate, the reading on the dial plate at the hinged position of the first swing arm 21 and the second swing arm 22, and the reading on the dial plate at the hinged position of each second swing arm 22 and the probe 4 to be the same as the reading recorded before taking out the caliper gauge, so that the caliper gauge is restored to the state when measuring at the outer side of the part to be measured, and then measuring the distance between the two pointers through a graduated scale or other measuring tools, namely, the distance between the grooves on the outer surface of the object.

Example two:

referring to fig. 2, an inside and outside groove caliper is disclosed, and the structure of the caliper in this embodiment is the same as that in the first embodiment, and will not be described herein again.

When measuring the groove arranged in the cavity of the part, firstly loosening the first joint locking nut 61, the second joint locking nut 62 and the third joint locking nut 63, putting the caliper gauge into the cavity of the part to be measured, adjusting the directions of the two probes 5 to enable the two probes 5 to be in a horizontal state and enable the needle points of the probes 5 to point to the object to be measured inwards, locking the third joint locking nut 63, respectively recording the reading of the scribed lines on each probe 4 on the dial corresponding to the probe, then adjusting the first swing arm 21 and the second swing arm 22 to enable the probes 5 to be tightly pressed against the outer wall of the object to be measured, then locking the first joint locking nut 61 and the second joint locking nut 62, respectively recording the reading of the two pointers 3 on the dial 1 and the reading of the scribed lines of each first swing arm 21 on the dial at the hinged part of the second swing arm 22 and the first swing arm 21, then loosening the first joint locking nut 61 and the second joint locking nut 62, taking out the caliper gauge, placing the caliper gauge on a horizontal table surface, adjusting the first swing arm 21 and the second swing arm 22, respectively adjusting the reading of the two pointers 3 on the dial plate, the reading on the dial plate at the hinged position of the first swing arm 21 and the second swing arm 22, and the reading on the dial plate at the hinged position of each second swing arm 22 and the probe 4 to be the same as the reading recorded before taking out the caliper gauge, so that the caliper gauge is restored to the state when measuring at the outer side of the part to be measured, and then measuring the distance between the two pointers through a graduated scale or other measuring tools, namely, the distance between the grooves on the outer surface of the object.

Of course, in the embodiment of the present invention, 1 second swing arm 22 is installed at the end of each first swing arm 21, and in other embodiments of the present invention, a plurality of second swing arms 22 may be sequentially hinged; the second swing arm 22 may not be provided, and the end of the first swing arm 21 away from the first joint lock nut 61 may be directly connected to the probe 4.
