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] like 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 ord...

Abstract

The invention discloses a measuring tape fixing device which comprises a positioning base and a rotary arm pivoted on the positioning base and provided with a measuring tape end hook positioning component. The measuring tape fixing device is fixed by the aid of the positioning base, a measuring tape end is fixed by the measuring tape end hook positioning component, and rotating angle is adjusted by the aid of the rotary arm, so that the measuring tape fixing device can meet measuring requirements of different angles.

Description

Technical field [0001] The invention relates to a device for assisting in fixing the end hook of the tape measure during tape measure measurement. Background technique [0002] When measuring with a tape measure, especially when measuring longer sizes, whether the end hook can be well fixed will directly affect the accuracy and efficiency of the measurement. In view of this requirement, Chinese patent documents with publication numbers CN1461401A and CN1945201A Different structural designs of end hooks have been proposed. However, 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 the tape measure. And this type of design is difficult to deal with when measuring diagonal dimensions such as the frame. [0003] Since the existing designs focus on the structural improvement of the tape measure itself, the overall effect is not good. Contents of the invention [...
