Embodiment Construction

[0013] Description will be made below in conjunction with the accompanying drawings. Such as figure 1 with 2 Shown, a kind of tree growth automatic display ruler, it comprises marking base 5 and iron scale 1, is provided with scale observation hole 3 in the center of marking base 5, is provided with permanent magnet 2 and guide way behind marking base 5, on iron The outer surface of the quality scale 1 is molded with a transparent plastic layer 7, the permanent magnet 2 sucks the iron scale 1 and is closely attached to the identification seat 5, and the iron scale 1 with the transparent plastic layer 7 slides left and right along the guiding path. Rollers are arranged on the transparent plastic layer 7 so that the overlapping transparent plastic layer 7 is easy to slide relative to each other. The scale observation hole 3 is a square hole or a circular hole. The guiding path is a crescent-shaped guiding path or a square-shaped guiding path. The crescent-shaped guiding path...

Abstract

An automatic ruler for displaying plant growth comprises an identification base and an iron scale ruler. The automatic ruler is characterized in that a hole used for viewing scales is arranged in the center of the identification base, permanent magnets and guide rails are arranged behind the identification base, the iron scale ruler is sealed by a layer of transparent plastic, the permanent magnets attract the iron scale ruler and attach to the back of the identification base, and the iron scale ruler with the layer of transparent plastic slides transversely. According to this arrangement, the use of nails to fix and energy consumption can be saved. The automatic ruler has the advantages of being simple in structure and low in cost, so that mass production can be achieved.

Description

technical field [0001] The proposal relates to a measuring tool, in particular to an automatic display ruler for tree growth during plant growth. Background technique [0002] Existing tree growth display devices have recorded and measured through electric control, complex structure, and short life. There is a simpler method of fixing the tape measure on the tree with screws, and the tape measure is fixed on the tree like a snail. Hurt, tape measures have a short lifespan on the outside. Contents of the invention [0003] The proposal provides an automatic display ruler for tree growth, which is simple in structure, low in cost, and easy to be mass-produced. [0004] The technical measures adopted in this plan are: an automatic display ruler for tree growth, which includes a marking base and an iron scale, and is characterized in that a scale observation hole is set in the center of the marking base, and a permanent magnet and a guide are arranged behind the markin...
