To the above, the utility model provides a slide caliper convenient to reading can fix the vernier on the main scale after the measurement is accomplished, and the reading is more convenient, improves measuring accuracy simultaneously.

The utility model discloses a realize through following technical scheme: the utility model provides a slide caliper convenient to reading, includes main scale, vernier scale, presses piece, buckle and connecting screw, the vernier scale cover is established in the main scale and the main scale bottom is equipped with the tongue, fixedly connected with depth chi on the lateral wall of vernier scale, the vernier scale bottom is equipped with the mounting groove that is used for installing the buckle, the buckle is "T" style of calligraphy structure, the buckle sets up the bottom at the main scale, the buckle top is seted up the recess that can supply the tongue card to go into, connecting screw hole has been seted up to the buckle bottom, press the piece to set up in the vernier scale bottom outside, press the piece to pass through connecting screw and buckle fixed connection, install reset spring between press piece and the vernier scale bottom.

As a preferred technical scheme of the utility model, including main scale clamp plate and fastening screw, the fastening screw has been seted up on the tail end of main scale, the chi clamp plate passes through fastening screw fixed connection on the main scale, just the degree of depth chi sets up between chi clamp plate and main scale.

As a preferred technical scheme of the utility model, the top of the head of main scale and vernier is equipped with the outer claw of measuring, the bottom of main scale and vernier is equipped with the interior claw of measuring.

Compared with the prior art, the beneficial effects of the utility model are that: the vernier caliper is additionally provided with the buckle, the pressing block, the reset spring and the connecting screw, the distance between the groove of the buckle and the main scale convex groove is controlled through the pressing block, and the friction force between the convex groove and the groove does not move relative to the position between the vernier and the main scale when reading can be realized, so that the reading is more convenient and accurate, the structure is simple, the operation is convenient, and the measuring accuracy is high.
