The present invention is a device that can be conveniently used to hold a person's height as a household product of the general household, the conventional keying mechanism is large and inconvenient to move the convenience can not be used conveniently in a general household and attach the scale to the wall The accuracy is poor when the key is scaled, and the discernment is weak when the key is frequently removed.

In the present invention, the conventional keying device is large and heavy, so there is no mobility, it is inconvenient to use in ordinary homes, so the volume is small and light, so it is easy to handle. The head is displayed accurately on the wall, and the horizontal level is installed so that the error of the key does not occur due to the horizontal error, and the height of the key can be displayed by the line indicator bar. I was.

The present invention makes the back of the case and the outer bottom of the case ⑦ at right angles, and the inside of the case is made of a container shape without a top lid for use as a pencil holder or a small box. A level bar is provided on the inner bottom of the case, and the penetrating groove is made longitudinally in the middle of the width of the lower part of the case, and the line is partially connected between the inner bottom of the case and the outer bottom of the case at the center of the groove horizontally and vertically. In order to be able to enter the middle space, attach the case spring ring in the front direction of the connection point and attach the line bar to the through groove located in the longitudinal direction in the middle of the width between the inner bottom of the case and the outer bottom. The rod spring ring is located near the front and the pointed end ⑤ connect the ⑨ rod spring ring attached to the line display bar and the case spring ring attached to the lower center of the case with ④ spring. The height of the outer surface of the case, which is the height of the person standing in front of the wall, is placed on the back wall by placing the keying device on the head of the person standing in front of the wall and pulling the bar to the front. By pulling down the tape measure on the inside of the back of the case and measuring the height to the sole of the foot, the height of the person, the height of the person can be accurately measured.

The effect of the invention is smaller and simpler than the conventional apparatus, which is convenient to handle, and can be used as a pencil holder.
