A bending plate 82 is fixed to one side of the placement plate 8, and the bottom of the bending plate 82 is clamped inside the card slot 81. An M-shaped partition 83 is fixed to the top of the placement plate 8.

[0041] It should be noted that the M-shaped partition 83 and the top of the placement plate 8 form a to-be-inspected area and a post-inspection area; the length and width of the bending plate 82 are the same as the length and width dimensions of the card slot 81. When it is necessary to batch-detect the washers, by clamping the bending plate 82 on one side of the placement plate 8 into the card slot 81 at the top of the workbench 1, and at the same time forming the to-be-inspected area and the post-inspection area by the M-shaped partition 83 on the top of the placement plate 8, the washers with unmeasured dimensions can be placed in the to-be-inspected area, and the inspected washers can be placed in the post-inspection area, thus avoiding the confusion between the unmeasured and inspected washers, facilitating the staff to distinguish the washers, and helping to improve the practicability of the device.

[0042] In this embodiment, a plurality of mounting blocks 9 are fixed to the side surface of the workbench 1 near the bottom. Mounting holes 91 are formed at the top of the mounting blocks 9. Through the arrangement of the plurality of mounting blocks 9, during use, place the workbench 1 in the working area, align the mounting holes 91 on the mounting blocks 9 with the holes in the working area, and by using the cooperation of bolts and nuts or pins, the mounting blocks 9 and the workbench 1 can be detachably mounted in the working area.

[0043] When this embodiment is used, the workbench 1 is placed in the work area, and the mounting holes 91 on the mounting block 9 are aligned with the holes in the work area. The mounting block 9 and the workbench 1 are detachably mounted in the work area by using the combination of bolts and nuts or latches. The block 21 in the detection mold 2 is placed on the inner side of the mold groove 11, and several screws 71 are screwed into the top of the several countersunk holes, and the bottom ends of the screws 71 are continuously screwed in until they are connected with the inner threads of the mold groove 11. The detection mold 2 can be fixed on the inner side of the mold groove 11, and the washers are placed In the inspection area, the bottom of the gasket will be placed on the top of several top pillars 31, the inner side will contact the side of the positioning pillar 23, and the outer side will contact the inner side of the inspection groove 22. The flushness of the top of the gasket and the top of the block 21, the fit of the inner side and the side of the positioning pillar 23, and the fit of the outer side and the inner side of the inspection groove 22 are observed in turn, and the key dimensions of the outer diameter, inner diameter and thickness of the gasket can be quickly inspected. After the inspection is completed, the pressure rod 51 is manually pressed down at one end of the front of the workbench 1. Since the key groove 53 on the side of the pressure rod 51 is located inside the fixing rod 54, the pressure rod 51 is pressed down. When the lever 51 is pressed, the end of the lever 51 located inside the placement groove 12 will tilt upwards, and the hinged connection between the one end of the lever 51 and the hinged plate 5 at the bottom of the connecting plate 3 can drive the connecting plate 3 to move upwards synchronously, and the telescopic rod 4 will be squeezed upwards to retract. At the same time, the return spring 41 will be subjected to the upward extrusion force applied, driving the connecting plate 3 and several supporting columns 31 upwards, and lifting the gasket in the detection groove 22 for the next gasket detection. When the upward force applied to the connecting plate 3 is cancelled, the return spring 41 will reset and push the telescopic rod 4 to extend and reset, and at the same time push the connecting plate 3 back to the position before moving upwards, further driving several supporting columns 31 to reset to the original height inside the detection groove 22, ensuring the reset effect after detection, so that it can cope with the rapid measurement of large batches of gaskets to be detected, unify the size specifications of the detection mold 2, avoid the influence of human factors, and cause inaccurate measurement results, thereby meeting the requirements of efficient and rapid detection, helping to improve production efficiency, and effectively reducing labor costs.
