[0024] As shown in the figure, Figures 1-6 The utility model discloses a detection equipment for measuring jig core hole, detection equipment includes plug gauge body 1, through end 2 and stop end 3, through end 2 and stop end 3 are connected with plug gauge body 1 both ends respectively through a plurality of connecting components, and connecting component includes connecting column 4, connecting rod 5 and limiting block 6, and one end of connecting column 4 is fixedly connected with one side of through end 2, and both ends of plug gauge body 1 are equipped with the clamping groove 7 matched with connecting column 4, and the outer side of connecting column 4 is equipped with a plurality of movable movable groove 8 for limiting block 6 and the fixed groove 9 for connecting rod 5, and the inside of movable groove 8 is communicated with the inside of fixed groove 9, and one end of limiting block 6 is connected with one side in the inside of movable groove 8 through elastic member, and one end of connecting rod 5 is located in the inside of fixed groove 9, and the bottom of connecting rod 5 is fixedly connected with the top of limiting block 6, and the inside of clamping groove 7 is equipped with a plurality of insertion grooves 10 matched with the shape of limiting block 6, when installing through end 2 and stop end 3, push pressing plate 11, make limiting block 6 move to the inside of movable groove 8 and extrude spring 15, and one end of connecting column 4 is inserted into the inside of clamping groove 7 opened in one end of plug gauge body 1, when one end of connecting column 4 and the inside bottom of clamping groove 7 are attached, release pressing plate 11, under the elastic action of spring 15, drive limiting block 6 to reset, so that one end of limiting block 6 is inserted into the inside of insertion groove 10, and the stability of through end 2 and stop end 3 when using is guaranteed through the cooperation between limiting block 6 and insertion groove 10 to limiting connecting column 4,

[0025] The end of the connecting rod 5 away from the fixed groove 9 is provided with a pressing plate 11, the pressing plate 11 is arc-shaped, the outer side of the plug gauge body 1 is provided with a flexible pad 12, the bottom of the pressing plate 11 is provided with a limiting rod 13, the bottom end of the limiting rod 13 is arc-shaped, the both ends of the plug gauge body 1 are provided with a plurality of recesses 14 matched with the bottom end of the limiting rod 13, the elastic member is a spring 15, one end of the spring 15 is fixedly connected with one side in the recess 14, the other end of the spring 15 is fixedly connected with one end of the limiting block 6, when the pressing plate 11 moves, the limiting rod 13 at the bottom slides on the surface of the plug gauge body 1, and the recess 14 provided at both ends of the plug gauge body 1 can block the bottom of the limiting rod 13, when the pressing plate 11 does not need to move, the cooperation of the limiting rod 13 and the recess 14 can improve the stability of the pressing plate 11, and because the bottom of the limiting rod 13 is arc-shaped, when the pressing plate 11 is pushed, the bottom end of the limiting rod 13 slides out of the recess 14, and the limiting rod 13 will not be stuck.

[0026] Working principle: when it is needed to replace the through end 2 and the stop end 3, the pressing plate 11 is pushed to move the pressing plate 11 outward of the connecting column 4, when the pressing plate 11 moves, the connecting rod 5 moves to the inside of the fixed groove 9, because the bottom of the connecting rod 5 is fixedly connected with the top of the limiting block 6, so the connecting rod 5 moves to move the limiting block 6 to the inside of the movable groove 8, and the limiting block 6 extrudes the spring 15, when the outside of the limiting block 6 is no longer in contact with the inside of the insertion slot 10, the through end 2 and the stop end 3 are pulled to take out the connecting column 4 from the inside of the clamping groove 7, so that the through end 2 and the stop end 3 are disassembled;

[0027] When the through end 2 and the stop end 3 are installed, the pressing plate 11 is pushed to move the limiting block 6 to the inside of the movable groove 8 and extrude the spring 15, one end of the connecting column 4 is inserted into the clamping groove 7 opened at one end of the plug gauge body 1, when one end of the connecting column 4 is in contact with the bottom end of the inside of the clamping groove 7, the pressing plate 11 is loosened, under the elastic action of the spring 15, the limiting block 6 is reset to insert one end of the limiting block 6 into the insertion slot 10, the cooperation between the limiting block 6 and the insertion slot 10 limits the connecting column 4, so that the stability of the through end 2 and the stop end 3 in use is ensured;

[0028] The arc-shaped pressing plate 11 can be more fitted to the palm of the user in use, so that the user can push conveniently, the flexible pad 12 provided at the outer side of the plug gauge body 1 can increase the friction between the palm of the user and the plug gauge body 1, and reduce the risk of the plug gauge body 1 falling off;

[0029] When the pressing plate 11 moves, the limiting rod 13 arranged at the bottom slides on the surface of the plug gauge body 1, and the bottom of the limiting rod 13 is blocked through the groove 14 arranged at both ends of the plug gauge body 1. When the pressing plate 11 does not need to move, the stability of the pressing plate 11 can be improved through the cooperation of the limiting rod 13 and the groove 14. Moreover, because the bottom of the limiting rod 13 is in an arc shape, when the pressing plate 11 is pushed, the bottom end of the limiting rod 13 can slide out of the inside of the groove 14, and the situation that the limiting rod 13 is stuck cannot occur.
