[0036] The measuring unit includes a primary nut disposed at the top of the rectangular housing. The primary nut is internally provided with a secondary nut, a tertiary nut, a quaternary nut, and a quinary nut.

[0037] The rotating unit includes an active bevel gear and a passive bevel gear disposed inside the rectangular housing, and the active bevel gear is externally connected to a rocker arm.

[0038] When measuring forgings, workers can control the simultaneous extension and retraction of each level of nuts by rotating a rocker arm. At the same time, each level of nut is marked with a scale, which can be adjusted and calculated according to the required dimensions of the forging.

[0039] Example 2

[0040] Reference Figure 1 , Figure 2 , Figure 4 , Figure 9 This is the second embodiment of the present invention. The difference between this embodiment and the first embodiment is that: a first through hole is provided at the central geometric position on the side of the rectangular shell that mates with the first-stage nut, and a telescopic bearing is provided inside the first through hole; a second through hole is provided at the geometric center of the bottom of the first-stage nut; and a first-stage movable groove is provided on the inner wall of the first-stage nut.

[0041] The rectangular housing protects the internal bevel gear structure from damage, and the primary nut protects the nuts and prevents them from taking up space when the other nuts are retracted.

[0042] The remaining structure is the same as that in Example 1.

[0043] Example 3

[0044] Reference Figure 1 — Figure 7 This is the third embodiment of the present invention. This embodiment differs from the second embodiment in that: the secondary nut is provided with a second through hole near the primary nut; the secondary screw is provided with a first thread through it, which engages with the primary screw; the secondary nut is provided with a primary limiting pin that engages with the primary movable groove; the inner wall of the secondary nut is provided with a secondary movable groove; the bottom end of the secondary nut is provided with a primary circular groove; the secondary screw is provided outside the primary circular groove; and the secondary screw is movably installed with a primary positioning pin within the primary circular groove.

[0045] The bottom end of the third-stage nut is provided with a third through hole, and a second thread is provided in the third through hole. The second thread is provided through the interior of the third-stage screw, and the second thread is engaged with the second-stage screw.

[0046] The tertiary nut is provided with a secondary limiting pin that cooperates with the secondary movable groove. The inner wall of the tertiary nut is provided with a tertiary movable groove. The bottom end of the tertiary nut is provided with a secondary circular groove. The tertiary screw is provided outside the secondary circular groove. The tertiary screw is movably installed with a secondary positioning pin in the secondary circular groove.

[0047] The fourth-stage nut has a fourth through hole at its bottom end, and a third thread is provided in the fourth through hole. The third thread is provided through the interior of the fourth-stage screw, and the third thread is engaged with the third-stage screw.

[0048] The fourth-level nut is provided with a third-level limiting pin that mates with the third-level movable groove. The inner wall of the fourth-level nut is provided with a fourth-level movable groove. The bottom end of the fourth-level nut is provided with a third-level circular groove. The fourth-level screw is provided outside the third-level circular groove. The fourth-level screw is movably installed with a third-level positioning pin within the third-level circular groove.

[0049] The fifth-level nut has a fifth through hole at the bottom and is completely closed at the top, with a chamfer on the outside. A fourth thread is provided in the fifth through hole, which engages with the fourth-level screw. The fifth-level nut is provided with a fourth-level limiting pin that cooperates with the fourth-level movable groove.

[0050] The outer walls of the primary, secondary, tertiary, quaternary, and quinary nuts are all marked with graduations for measurement. The primary screw rotates through the first thread, driving the secondary screw to rotate. Simultaneously, the secondary nut moves horizontally along the primary movable groove under the action of the primary limiting pin, achieving a telescopic effect. When the primary screw rotates clockwise, it can move the secondary nut closer to the bottom of the primary nut, mainly for retracting the nut. If the primary screw rotates counterclockwise, it moves the secondary nut away from the bottom of the primary nut, mainly for measuring the dimensions of forgings. The secondary, tertiary, and quaternary screws have the same effect as the primary screw. The primary circular groove and the primary positioning pin cooperate to fix the secondary screw at the bottom of the secondary nut for rotation, and the effect produced by the secondary circular groove and the secondary positioning pin is the same as described above. The tertiary circular groove and the tertiary positioning pin cooperate in the same way, so that each nut can only move horizontally.

[0051] The remaining structure is the same as that in Example 2.

[0052] Example 4

[0053] Reference Figure 1 — Figure 2 , Figure 8 — Figure 9This is the fourth embodiment of the present invention. The difference between this embodiment and the third embodiment is that the passive bevel gear inside the rectangular housing has a rotating shaft at its geometric center. The rotating shaft passes through the first through hole and the telescopic bearing and is connected to the first-stage screw.

[0054] The drive bevel gear inside the rectangular housing has a drive shaft located at its geometric center. The rectangular housing has a rotating hole at one end near the drive shaft, and a rotating bearing is installed in the rotating hole.

[0055] The clockwise rotation of the active bevel gear drives the passive bevel gear to rotate clockwise, and the clockwise rotation of the passive bevel gear drives the primary screw to rotate clockwise via the telescopic bearing. Conversely, the counterclockwise rotation of the active bevel gear drives the passive bevel gear to rotate counterclockwise, and the counterclockwise rotation of the passive bevel gear drives the primary screw to rotate counterclockwise via the telescopic bearing.

[0056] The remaining structure is the same as that in Example 3.

[0057] It should be noted that the above embodiments are only used to illustrate the technical solution of this utility model and are not intended to limit it. Although this utility model has been described in detail with reference to preferred embodiments, those skilled in the art should understand that modifications or equivalent substitutions can be made to the technical solution of this utility model without departing from the spirit and scope of the technical solution of this utility model, and all such modifications or substitutions should be covered within the scope of the claims of this utility model.
