Alerting structure of electronic torque tool
An alerting structure of an electronic torque tool includes a tool body and an electronic module. The electronic module includes a sensing unit, a processing unit, and at least one display unit. The sensing unit senses an operational value of the tool body. The processing unit sends the operational value sensed by the sensing unit to the display unit. The display unit has at least one display block. When the operational value sensed by the sensing unit reaches a predetermined value, the processing unit generates a rotation signal in order for the contents displayed by the display block of the display unit to rotate back and forth through a predetermined angle and thereby produce a conspicuous alerting effect.
1. An alerting structure of an electronic torque tool, comprising:
a tool body having a shank, wherein the shank has a front end with a working head and a rear end forming a gripping end; and
an electronic module comprising a sensing unit, a processing unit, and at least one display unit, wherein the sensing unit is provided on the shank of the tool body and is configured to sense an operational value of the torque tool, the processing unit is electrically connected to the sensing unit and the display unit, and after the sensing unit sends the operational value sensed thereby to the processing unit, the processing unit sends the operational value to the display unit;
wherein the display unit has at least one display block for displaying the operational value, and when the operational value sensed by the sensing unit reaches a predetermined value, the processing unit generates a rotation signal in order for contents displayed by the display block of the display unit to rotate back and forth through a predetermined angle and thereby produce an alerting effect.
2. The alerting structure of claim 1 , wherein the display unit has at least two said display blocks, and the contents displayed respectively by the display blocks are rotated independently.
3. The alerting structure of claim 2 , wherein the contents displayed respectively by the display blocks of the display unit are rotated in a same direction simultaneously.
4. The alerting structure of claim 2 , wherein the contents displayed respectively by the display blocks of the display unit are rotated simultaneously but in different directions.
5. The alerting structure of claim 2 , wherein the contents displayed respectively by the display blocks of the display unit are rotated in different directions.
6. The alerting structure of claim 1 , wherein the display unit further comprises a stationary display block, and after the display unit receives the rotation signal, contents displayed by the stationary display block stay in place without being rotated.
7. The alerting structure of claim 2 , wherein the display unit further comprises a stationary display block, and after the display unit receives the rotation signal, contents displayed by the stationary display block stay in place without being rotated.
8. The alerting structure of claim 1 , wherein the predetermined angle through which the contents displayed by each said display block of the display unit are rotated is 90°.
9. The alerting structure of claim 2 , wherein the predetermined angle through which the contents displayed by each said display block of the display unit are rotated is 90°.
10. The alerting structure of claim 1 , wherein each said display block of the display unit is configured to display one of text, a number, and a pattern.
11. The alerting structure of claim 2 , wherein each said display block of the display unit is configured to display one of text, a number, and a pattern.
12. The alerting structure of claim 2 , wherein the shank has a longitudinal direction defined as a direction between the front end and the rear end of the shank, and the display blocks are arranged along the longitudinal direction of the shank.
13. The alerting structure of claim 1 , wherein the operational value of the tool body is a torque value or an angle value.
