Abstract

The present invention relates to a caliper button structure, which comprises a button and a caliper shell, and is characterized in that a button hole is formed on the handle part of the caliper shell, and a button is arranged inside the button hole; a small spring is arranged between the button and a supporting part inside the caliper shell; a connection rod is directly or indirectly connected with the button; the connection rod is provided with a compression spring; one end of the compression spring is supported on a fixed part of the caliper shell, and the other end is engaged with a pallet in contradiction way that controls the rotation action of a ratchet wheel disc; the pallet is fixed inside the caliper shell through a pin, and a torsion spring is arranged between the pallet and the caliper shell. The button structure is applicable to the caliper with a frame-typed structure, and has reasonable and simple structure, and is easy to be produced and assembled.

Description

technical field [0001] The invention relates to a long button structure. Background technique [0002] There are roughly two types of ordinary tape measures that can be seen on the market today. The tape is recovered by spring force. The spring and the core are mounted on the same axis. After the tape is pulled out by hand, the spring contracts to gather energy. After the tape is released by hand, it is recovered by elastic force. Tape, but the tape of this kind of tape generally does not exceed 10M. When the measuring tape is relatively long, once it exceeds 10M, it will be wound on the core of the measuring tape, which will cause the measuring tape to be relatively large in size, which is not easy to hold and use, and if the elastic force of the spring is too large, it is easy to cause the measuring tape to cut people's hands, and the elasticity is not enough. It is easy to cause the ruler tape to not be wound back on the ruler core smoothly, so further improvement is nee...
