[0002] The current simple vernier calipers are generally made of plastic, although the cost is low, but due to the easy deformation and the shrinkage of the plastic in the manufacturing process, the measurement reading error is relatively large, and it is also easy to break, which is inconvenient to use and carry. The accuracy is high, but the price is expensive. In business and daily life, there are some occasions that only need rough measurement and estimation, and do not need the accuracy of ordinary vernier calipers. In addition, it is best for students to have a hand when learning to use vernier calipers. , but it is difficult to satisfy because of the high price, so this part of users will need a simple vernier caliper that does not require high precision, is not easy to deform, is cheap and practical, and can be carried around and used at any time.

Embodiment Construction
[0038] Below in conjunction with accompanying drawing, simple and easy vernier caliper of the present invention is described in more detail.
[0039] Depend on Figure 1-2 As shown in 5, the simple vernier caliper of the present invention includes the simple vernier caliper of the present invention including the main ruler 1 and the auxiliary ruler 2 with scales, and the main ruler 1 and the auxiliary ruler 2 are made of sheet metal materials, wherein the auxiliary ruler 1 The chute 3 where the ruler 2 slides and cooperates with the main ruler 1 is a bent hook groove, and the two sides of the main ruler 1 have guide surfaces 4 corresponding to the shape of the hook groove, and the main ruler 1 and the auxiliary ruler 2 One of them will bend and stagger a chi wall thickness in the two outer dimension measuring heads 5, so that the plate surface is flush when the two measuring heads 5 are in contact.

Abstract
The related simple vernier caliper comprises: a main scale (1) and a secondary scale (2) both made from metal sheets, a warped sliding slot (3) for fit, two guide surfaces on (1) sides opposite to (3), and two external size measuring heads (5) of (1) and (2) with one being warped as the scale wall width to let heads contact flush. Wherein, this invention can be stamped for form while etching for scale both low cost and high precision, and has wide application.
Description
technical field [0001] The invention relates to a simple vernier caliper for measuring. Background technique [0002] The current simple vernier calipers are generally made of plastic, although the cost is low, but due to the easy deformation and the shrinkage of the plastic in the manufacturing process, the measurement reading error is relatively large, and it is also easy to break, which is inconvenient to use and carry. The accuracy is high, but the price is expensive. In business and daily life, there are some occasions that only need rough measurement and estimation, and do not need the accuracy of ordinary vernier calipers. In addition, it is best for students to have a hand when learning to use vernier calipers. , but it is difficult to satisfy because of the high price, so these users will need a simple vernier caliper that does not require high precision, is not easy to deform, is cheap and practical, and can be used at any time.
