[0002] Lower limb circumference refers to the measurement of the circumference or diameter of the lower limbs (usually the calf and thigh). It is usually one of the indicators used to assess the risk and treatment effect of deep vein thrombosis (DVT) in the lower limbs. When treating the patient's lower limb circumference, it is necessary to measure the circumference of the lower limb with a measuring ruler.

[0003] However, when using the measuring ruler in the prior art, the circumference of the patient's lower limbs is often measured by retracting the measuring tape, and the multi-point positioning effect of the measuring ruler is not high, which makes it inconvenient for medical staff to measure the lower limbs by retracting the measuring tape when measuring the circumference of the patient's lower limbs, and affects the accuracy of the measurement data, which affects the effect of the treatment of the patient's lower limbs. Therefore, a vernier caliper with multi-point positioning is needed. Utility Model Content

[0007] Preferably, the position distribution of the measuring caliper and the auxiliary caliper is symmetrical about the central axis of the adjustment plate.

[0008] Preferably, the card slots are arranged in a straight line shape and at equal intervals on the surface of the adjustment plate.
