Problems solved by technology

[0002] When measuring with a tape measure, especially the measurement of a longer size, whether the end hook can be well fixed will directly affect the accuracy of the measurement and the efficiency of the measurement. In view of this requirement, the publication numbers are CN1461401A and CN1945201A Chinese patent documents Different structural designs of the end hooks are proposed, but due to the limitation of the hook head, its overly complex structural design and excessive space occupation will affect the traditional use occasions and methods of use of the tape measure
And this kind of design is difficult to deal with when making diagonal dimensions such as frames
[0003] The overall effect is not good because the existing designs focus on the structural improvement of the tape measure itself

Embodiment Construction

[0026] Such as Figure 1 to Figure 2 In the tape measure fixing device shown, the vertical positioning plates 110 and 120 are connected together through the connecting plate 130 at the upper end, and there is a spare avoidance groove 140 in the middle of the positioning plates 110 and 120. After the positioning plates 110 and 120 are extended respectively, the two The extended parts of the latter intersect each other to form a right-angled structure, and the positioning plates 110 and 120 are used to stabilize and position the entire fixture to form a positioning base; wherein, the sides of the positioning plates 110 and 120 are also used as workpieces or Measure the edge of the object. In order to facilitate the measurement of metal workpieces, the side walls / sides of the inner and outer sides of the positioning plates 110 and 120 form the right-angle positioning surfaces of the workpiece, which can be used to locate the inner right angle or outer right angle respectively. In ...

Abstract

The invention discloses a measuring tape fixing device, which comprises a positioning base and a rotating arm pivotally connected to the positioning base, and a positioning part of a tape end hook is arranged on the rotating arm. It fixes the device through the positioning base, fixes the end of the tape with the hook positioning part of the end of the tape, and adjusts the rotation angle by means of a rotatable arm to meet the measurement needs of various angles.

Description

technical field [0001] The invention relates to a device for auxiliary fixing the end hook of the tape measure when measuring the tape measure. Background technique [0002] When measuring with a tape measure, especially the measurement of a longer size, whether the end hook can be well fixed will directly affect the accuracy of the measurement and the efficiency of the measurement. In view of this requirement, the publication numbers are CN1461401A and CN1945201A Chinese patent documents Different structural designs of the end hooks have been proposed, but due to the limited function of the hook head, its overly complex structural design and excessive space occupation will affect the traditional use occasions and methods of using the tape measure. And this kind of design is difficult to deal with when measuring the diagonal size of the frame, for example. [0003] Because existing designs all focus on the structural improvement of tape measure itself, thereby overall effec...
