Further, when the position of the adjusting seat 801 needs to be adjusted according to the requirement of the clamping object, the adjusting seat 801 is rotated to rotate on the rotating seat 805 through the rotating groove 804, so that the plurality of rotating grooves 804 respectively squeeze the plurality of positioning rods 807, and then the positioning rods 807 are stressed and contracted, and meanwhile, the positioning rods 807 move in the telescopic movable grooves 806 and drive the positioning springs 809 to bear force, so that after the adjusting seat 801 is adjusted in place, the plurality of positioning rods 807 are driven to reset under the resilience force of the plurality of positioning springs 809 and clamped in the plurality of positioning grooves 808, and the position of the adjusting seat 801 can be fixed; in addition, when the calibrator 1 is installed on a clamped object, one clamping and positioning frame 802 is rotated to drive the corresponding gear 810 to rotate, the gear 810 rotates in the installation groove 812 through the gear shaft 811, the gear shaft 811 can drive the torsion spring 813 to bear force when rotating, meanwhile, one gear 810 rotates to drive the corresponding other gear 810 to rotate, and then the other clamping and positioning frame 802 is driven to rotate, so that the two clamping and positioning frames 802 can be synchronously unfolded, then placed at the clamping position, the clamping and positioning frames 802 are loosened, and then the two gear shafts 811 can drive the two gears 810 to reset under the rebound force of the two torsion springs 813, and then drive the two clamping and positioning frames 802 to reset, so that the sleeve joint box 5 is installed very conveniently and efficiently.

The foregoing is only a preferred embodiment of the present invention, but the scope of the present invention is not limited thereto, and any person skilled in the art, who is within the scope of the present invention, should make equivalent substitutions or modifications according to the technical scheme of the present invention and the inventive concept thereof, and should be covered by the scope of the present invention.
