Description

  The present invention relates to a kind of external device for a manual tool, and more particularly to an external measurement device that can acquire the rotation angle of a manual tool.

  Please refer to FIG. According to a known technique, in order to measure the rotation angle of the connector 1a ′ of the drive head of the spanner 1a, an angle gauge 2 is installed on the connector 1a ′, and the angle gauge 2 has a scale 3, thereby the spanner When turning 1a, the rotation angle of the scale 3 of the angle gauge 2 is recorded to obtain the rotation angle of the connector 1a '. However, the operation is troublesome and has a large error due to manual work, which satisfies the user's request. I can't let you.

  In another known spanner 1b shown in FIG. 2, in order to measure the rotation angle of the connector 1b ′ of the drive head, an angle measuring device 5 is fitted to the housing 4 of the spanner 1b, and the transmission line 5 ′. The angle measuring device 5 is electrically connected to a control system (not shown) and the display device 6, and the angle measuring device 5 is installed in accordance with the outer shape of the housing 4. The angle measuring device 5 is a gyroscope. It can measure the amount of angular rotation and input it to the control system provided in the spanner 1 b and display it on the display device 6. Such an angle measuring device 5 cannot be used unless it is combined with a specific spanner 1b and its specific control system and display device 6, and its commonality is low, cumbersome and inconvenient to use, and has a relatively low error. Large and high in structural complexity.

  FIG. 3 shows a spanner 1c capable of measuring a rotational angle described in Patent Document 1, which is that the angle measuring system 7 detects the rotational angle of the connector 1c ′ of the drive head of the spanner 1c, and the number of rotational angles allows the workpiece to be measured. Evaluate the degree of tightening. The spanner 1c capable of measuring the rotation angle cannot be shared with other tools or arbitrarily exchanged the use position. Therefore, the manufacturing cost is high, the structure is relatively complicated, and the scene where it is used is Not wide.

  FIG. 4 is another example described in Patent Document 1, which discloses a spanner 1d capable of measuring a rotation angle, in which an angle measurement system 8 detects a rotation angle of a connector 1d 'of a drive head of the spanner 1d. Such an angle measuring system of the spanner 1d capable of measuring the rotation angle is directly mounted in the spanner 1d, and therefore cannot be shared with other tools, and the operating range is small.

  In the above-described known structure, the angle gauge 2, the angle measuring device 5, and the angle measuring systems 7, 8 are directly or directly attached to the spanners 1a, 1b, 1c, 1d, even if the operation is difficult or not difficult. Therefore, it can be used only for a specific spanner and cannot be used for other spanners. Therefore, it cannot be widely used, and its structure is complicated, so that the price is relatively high.
