Embodiment

[0010] Briefly describe the present invention according to the diagram:

[0011] As shown in the figure: 1 is the shell, 2 is the coil, 3 is the fixed nail, 4 is the magnet, 5 is the clutch, 6 is the tape measure, 7 is the measuring device weight, 8 is the positioning ruler, and 9 is the chain roller.

[0012] The connection of this structural diagram is as follows: the tape measure shell 1 covers the coil 2, and the coil 2 is pulled back to the chain drum 9 by external pulling force, and the drum rotates and the clutch controller 5 is pushed forward to control the recovery of the tape tape 6, and the clutch 5 Pushing back can control the recovery of the tester coil, the coil is connected to the tester weight 7, the tester weight 7 is connected to the positioning ruler 8, the fixed nail 3 is equipped with a bow spring that can be automatically recovered and flat-turned, and the fixed nail 3 passes through Shell 1, the force of the nail point can lock the measuring device on th...

Abstract

The invention is fit to industry, building industry and other fields, and has wide usage. It is exact a tape measurement apparatus two-in-one of usage convenience, shortcut, practice, integration of tape and measuring apparatus two-in-one. The vertical weight dropper of the product can secede from tape arbitrarily. Using tape is same to other tapes. When using measuring apparatus, knot the vertical weight dropper back to small pull loop of line loop and acts freely. It is portable and can reduce cost.

Description

Technical field: [0001] The present invention is applicable to fields such as industry and construction industry, and has a wide range of uses. Specifically, it is a two-in-one tape measure measuring device. Background technique: [0002] The tape measures currently on the market are generally used for measuring sizes. If vertical line is to be measured, a measuring device must be purchased in addition, so the usage is single and cannot satisfy people's needs. Invention content: [0003] The object of the present invention is to solve the above disadvantages and provide a two-in-one tape measuring device that is convenient to use, fast and practical, and integrates the tape measure and the measuring device. [0004] The technical solution adopted by the present invention to solve its technical problems is: the connection of this structural diagram is such that the measuring tape shell encloses the recovery connecting strip. The sliver is recovered from the sliver drum b...
