By providing the first measuring cylinder 601, the first prism diameter measuring guide head 602, the second prism diameter measuring guide head 603, the first comparison piston 604, the first return spring 605, the first light-transmitting glass plate 606, the sponge block 607, the second measuring cylinder 608, the first longitudinal and transverse diameter measuring guide head 609, the second longitudinal and transverse diameter measuring guide head 610, the second comparison piston 611, the second return spring 612 and the second light-transmitting glass plate 613, the hydraulic signal can be converted into a displacement signal, ensuring relatively accurate values are obtained after cooperating with the transparent scale bar 104.

[0035] Working principle: When in use, power on the supplementary light 105. The supplementary light 105 passes through the first light-transmitting glass plate 606, the second light-transmitting glass plate 613 and the transparent scale bar 104 from inside the support shell 101 and irradiates outward, so that the positions of the transparent scale bar 104 and the scale reference ring can be clearly seen. Push the movable measuring plate 203 to open the space between the movable measuring plate 203 and the fixed measuring plate 206. Place the walnut between the two toothed plates 207 and then release the movable measuring plate 203. The clamping spring 205 presses the movable measuring plate 203. At the same time, adjust the position of the walnut so that the edges of the walnut are stuck between the two toothed plates 207 and are aligned. At this time, the edge diameter of the walnut is approximately equal to the distance between the two toothed plates 207, which is also equal to the opening distance of the movable measuring plate 203, and is also equal to the moving distance of the active piston 304 after the movable measuring plate 203 is opened. It is also proportional to the volume of the hydraulic oil discharged from the inside of the edge diameter measuring active cylinder 302. Since there is a hydraulic transmission between the edge diameter measuring active cylinder 302 and the first measuring cylinder 601, after the active piston 304 moves a certain distance, the first reference piston 604 will displace a certain distance on the transparent scale bar 104 on one side of the first measuring cylinder 601 in the same proportion. Therefore, observing the reading of the scale reference ring on the first reference piston 604 on the transparent scale bar 104 is the edge diameter of the walnut at this time; When pressing the two vertical and horizontal diameter measuring piston columns 505, the hydraulic oil will be pressed into the second measuring cylinder 608 through the docking hose 507, the first drainage pipe 512, the second drainage pipe 513, the drainage three-way pipe 514 and the drainage main pipe 515, and squeeze the second reference piston 611 from one end of the second vertical and horizontal diameter measuring guide head 610, so that the scale reference ring on the second reference piston 611 retreats from the full scale of the transparent scale bar 104 to the measured scale. At the same time, the hydraulic oil at the other end of the second reference piston 611 is discharged into the return main pipe 511 through the first vertical and horizontal diameter measuring guide head 609, and then returns to the inside of the two vertical and horizontal diameter measuring active cylinders 501 through the first return pipe 508, the second return pipe 509 and the docking hose 507 respectively. Due to the hydraulic transmission, the distance between the two vertical and horizontal diameter measuring piston columns 505 is equal to the distance that the second reference piston 611 slides outward from the zero scale; After measuring the edge diameter of the walnut, adjust the position of the vertical and horizontal diameter measuring piston columns 505 so that the ends of the vertical and horizontal diameter measuring piston columns 505 are aligned with the middle of the walnut. Press the two vertical and horizontal diameter measuring piston columns 505 toward the middle. After the two vertical and horizontal diameter measuring piston columns 505 are all in contact with the walnut, observing the reading of the scale reference ring on the second reference piston 611 on the transparent scale bar 104 is the horizontal diameter of the walnut at this time; After measuring the transverse diameter of the walnut, twist the support plate 201. The support plate 201 drives the connecting cylinder 208 to rotate, so that after the walnut rotates 90 degrees, the positioning beads 212 are clamped into the corresponding positioning holes 210 for positioning. At this time, adjust the position of the vertical and horizontal diameter measuring piston column 505 again, so that the end of the vertical and horizontal diameter measuring piston column 505 is aligned with the middle of the walnut. Press the two vertical and horizontal diameter measuring piston columns 505 towards the middle. After the two vertical and horizontal diameter measuring piston columns 505 are both in contact with the walnut, observe the reading of the scale control ring on the second control piston 611 on the transparent scale bar 104, which is the vertical diameter of the walnut at this time; When adjusting the position of the vertical and horizontal diameter measuring piston column 505, twist the torsion wheel 406. The torsion wheel 406 drives the threaded column 405 to rotate. When the threaded column 405 rotates, it moves along the threaded cylinder 407, and at the same time drives the connecting sleeve 403 and the vertical and horizontal diameter measuring main cylinder 501 to move synchronously, and then drives the vertical and horizontal diameter measuring piston column 505 to move synchronously to ensure that the vertical and horizontal diameter measuring piston column 505 is aligned with the middle of the walnut; After the measurement is completed, turn off the supplementary light 105, push the moving measurement plate 203, so that the space between the moving measurement plate 203 and the fixed measurement plate 206 is opened, and take out the walnut.
