Outer spring and inner spring, be separately positioned on the both sides of push-and-pull seat;
Sliding axle, pass and be slidably connected in push-and-pull seat, outer spring and inner spring, sliding axle two ends are screwed onto the two ends of groove;
Vernier scale corresponding groove place is provided with a perspective groove, in order to observe the scale mark on push-and-pull seat.
Preferably, the scale mark on push-and-pull seat comprises two parts: left-hand scale line and right side scale line, lays respectively at left side and the right side at the top of push-and-pull seat.
Preferably, in perspective groove, window is installed.
Preferably, window is respectively arranged with a left scale line and a right scale mark, under measuring state, the left scale line on window aligns with the left-hand scale line of push-and-pull seat, or the right scale mark on window aligns with the right side scale line of push-and-pull seat.
Preferably, left-hand scale line and right side scale line comprise some scale marks respectively, and length respectively ecto-entad increases gradually, in order to show the dynamics of push-and-pull under measuring state.
Preferably, vernier is also connected with a pressing plate, prevents vernier to be separated with main scale by pressing plate and vernier scale.
Preferably, pressing plate and vernier scale are connected by screw main scale.
Preferably, also comprise a pit gauge, be slidably connected on main scale.
By the present invention, the power that user's measuring workpieces applies can be controlled, make its ergometry in allowed limits, both protected vernier caliper not to be damaged, ensure the accuracy of measurement data simultaneously, enhance productivity.
