Description

Multifunctional measuring tape

Technical Field

The invention relates to the technical field of measuring tools, in particular to a multifunctional measuring tape.

Background

Measuring tapes are common tools in daily life. The tape measure may comprise a body, a tape reel (tape reel) and a tape measure blade (measuring tape blade). The body houses a spool about which the tape measure blade is wound, and at least a portion of the tape measure blade. The body further includes a slot through which the distal end of the tape measure blade extends from the body. A tab (tab) or hook may be attached to the distal end of the tape blade. The projection may allow the distal end of the tape blade to be secured to an object.

Such tape measures may allow a craftsman to measure objects having dimensions that far exceed the craftsman's reach. For example, the craftsman may secure the tab at one end of an object and take the tape measure to the other end of the object. Assuming that the tab remains fixed to the object, moving the tape measure towards the other end of the object will cause the tape measure blade to unwind from the reel and thereby extend from the body. The craftsman can then view the measuring indicia on the tape blade to determine the length of the extended tape blade and thereby measure the length of the object.

The inventor finds in research that the conventional tape measure has at least the following disadvantages in use:

when the traditional measuring tape is used, the traditional measuring tape only has a measuring function and is mainly used for measuring straight lines, and the traditional measuring tape is single in function and cannot be used for other independent operations. The operation needs to be matched with other tools for use, so that great inconvenience is brought to the operation of people.
