A No. 3 threaded hole 105 is arranged at each of the four corners of the upper end face of the movable base plate 112. Two No. 1 sliding grooves 106 are arranged on the upper end face of the movable base plate 112 near the two sides. Two No. 2 sliding grooves 107 are arranged on the upper end face of the movable base plate 112 between the four No. 1 sliding grooves 106. A No. 1 fixed groove 108 is arranged on the upper end face of the movable base plate 112 on the front and rear sides of the four No. 1 sliding grooves 106. A No. 2 fixed groove 109 is arranged on the upper end face of the movable base plate 112 between two of the four No. 1 sliding grooves 106. The fixed base plate 101 is fastened together with the movable base plate 112 through the screw thread cooperation of a No. 1 screw 111 and the No. 1 threaded hole 102.

[0030] Specifically, the movable base plate 112 is fastened and connected with the fixed base plate 101 through the screwing cooperation of the four first screws 111 with the four first threaded holes 102. When the movable base plate 112 needs to be replaced, only the four first screws 111 need to be removed for replacement. The four first fixing grooves 108 and the second fixing grooves 109 respectively formed on the upper end surface of the movable base plate 112 can prevent the operation from being affected by the protrusions of the ruler 5 and the fixed frame body 4.

[0032] Specifically, the close cooperation of the two first sliding blocks 210 on the lower end surface of the outer jaw housing 201 with the two first sliding grooves 106 and the close cooperation of the second sliding block 209 with the second sliding groove 107 can keep the front and rear ends of the outer jaw housing 201 on the same horizontal line at all times to prevent deviation. The inner wall 202 of the outer jaw housing 201 is provided with a third sliding groove 203 on the inner bottom surface near the front and rear ends, so that the inner jaw body 3 can be slidably arranged in the inner wall 202 through the third sliding block 306. The threaded cooperation of the first threaded rod 207 with the second threaded hole 104 through clockwise or counterclockwise rotation can realize the sliding arrangement of the outer jaw housing 201 in the pushing or pulling direction.

[0033] Referring to Figure 2 , Figure 6The two inner jaw bodies 3 comprise inner jaw housings 301, anti-skid pads 302 are fixedly arranged on the inner walls of the front and rear sides of the two inner jaw housings 301, two No. 2 rotating grooves 307 are formed in the middle of the inner walls of the left and right sides of the two inner jaw housings 301, No. 2 rotating plates 305 are embedded and connected to the inner walls of the two No. 2 rotating grooves 307, No. 2 threaded rods 303 are rotatably sleeved to the outer walls of the two No. 2 rotating plates 305, No. 3 sliding blocks 306 are fixedly arranged at the lower end surfaces of the two inner jaw housings 301, No. 2 anti-skid caps 304 are sleeved to the left and right sides of the outer walls of the two No. 2 threaded rods 303, and the four No. 3 sliding blocks 306 are slidingly arranged in the No. 3 sliding grooves 203.

[0034] Specifically, the two No. 3 sliding blocks 306 at the lower end surfaces of the inner jaw housings 301 are in close cooperation with the No. 3 sliding grooves 203, so that the front and rear ends thereof can always remain on the same horizontal line to prevent deviation. Since the anti-skid pads 302 are fixedly arranged on the inner walls of the left and right sides of the front and rear sides of the inner jaw housings 301, slippage can be effectively prevented when the circular metal part is fixed. The No. 2 threaded rods 303 are rotated clockwise or counterclockwise to be screwed with the No. 5 threaded holes 206, so as to slidingly arrange the inner jaw housings 301 to be pushed or pulled.

[0035] Referring to Figure 1 , Figure 7 The two fixed frame bodies 4 comprise fixed supports 401, support fixed blocks 402 are fixedly arranged at the front and rear ends of the outer walls of the two fixed supports 401, and the four support fixed blocks 402 are fastened in the No. 1 fixed groove 108 by being screwed with the two No. 2 screws 403 and the No. 4 threaded holes 110.

[0036] Specifically, the fixed frame body 4 can prevent the outer jaw body 2 from moving and falling off, and can always maintain precision.

[0037] Referring to Figure 1 , Figure 8 The ruler 5 comprises a scale 501 and two No. 3 screws 502, and the scale 501 is fastened in the No. 2 fixed groove 109 by being screwed with the two No. 3 screws 502 and the No. 6 threaded holes 113.

[0038] Specifically, the scale 501 can be used to more intuitively observe the metal part and correct it.

[0039] Working principle: the metal parts need to be corrected between the two outer jaw body 2, if it is polygon or irregular shape metal parts, only need to push the outer jaw shell 201 by rotating the first threaded rod 207. If it is a circular component first slightly adjust the overall position of the outer jaw, then rotate the second threaded rod 303 push the inner jaw shell 301, metal parts fixed for correction. Correction tool long time use will cause wear and tear, need to replace the outer jaw body 2 or inner jaw body 3, the outer jaw body 2 need to first four two screws 403 unscrew, remove the fixed frame body 4, remove the first anti-skid cap 208, the outer jaw body 2 from the side plate 103 in the second threaded hole 104 of the first threaded rod 207. The inner jaw body 3 need to remove the second anti-skid cap 304, the second threaded rod 303 from the outer jaw shell 201 of the five threaded hole 206. Caliper 501 only need to unscrew the two ends of the third screw 502. Replace the movable bottom plate 112, remove the outer jaw body 2, inner jaw body 3 and ruler 5, unscrew the fixed bottom plate 101 upper surface four corners of the first screw 111.
