Displayed on different display screens. The function of the lock screen is such that the operating unit does not perform the sensing signal of the position sensor (30) or suspend the function of the position sensor. The above-mentioned function of locking or unlocking can be performed by other buttons.

The mode of use of this embodiment will be described below, and a gravity sensor is used as the orientation sensor (30) for illustration.

In general, when the wrench is operated, the height of the eye is above the wrench. Therefore, the effect of the fifth to seventh figures is to set the numerical display orientation to the upward direction so that the value is displayed on the upward display screen (ie, Contrary to the display of gravity.)

As shown in the fifth figure, the driving head (18) of the wrench (10) drives a screw (41) through a sleeve (40), and the screw is screwed on a horizontal plane; at this time, gravity sensing After sensing the direction of gravity, the display screen (20) can be operated to display the display screen (20), so that the relevant data will be displayed by the display screen (20), including when the screw (41) is driven. Torque value for users to watch and read. In the present embodiment, the other two display screens (22) (24) that are not facing upward are set to not display numerical values.

In the state of use of the sixth figure, the wrench (10) drives a screw (42) through a sleeve (40), the screw is screwed to the standing surface; at this time, the wrench is oriented on the vertical axis (at this time) S) rotating 90 degrees for the center, after the gravity sensor (30) senses the direction of gravity, it can be judged that the display screen (24) is the display screen facing upward, and therefore, the display screen (24) will display data for use. Learn about the torque that drives the screw.

In the state of use of the seventh figure, the wrench (10) drives a screw (43) screwed on the upright surface. At this time, the wrench can judge that the display screen (22) is an upward display screen, and The display (22) displays the values.

In addition, if the direction of gravity is just between two of the display screens, such as display screens (20) and (24), the two display screens will display values. For example, in the eighth figure, if the screw (44) driven by the wrench (10) is located on a slope, and the rotation angle of the wrench is between 35 degrees and 55 degrees, the two display screens (20) ) (24) will display the value. That is, in the range of positive and negative δ degrees of gravity direction (G), the upward angles of the two display screens (20) (24) are the same or about the same, so that the values are simultaneously displayed on the two display screens, the user The information can be read by the two display screens or one of the display screens at the same time. The δ angle of the embodiment is an angular range of 10 degrees, and may also be in the range of 5 degrees or 15 degrees.

The switch button (15) can be pressed to switch the value to another display (20) for display, and the user can obtain information from the display screen (20) facing one side. Press the toggle button (15) again and the value will be displayed from the display (20) to the next display (22), as shown in Figure 11. Therefore, when the button (15) is pressed, the value will be switched in a clockwise sequence (also in a counterclockwise order) according to the display screen (20), the display screen (22) and the display screen (24) to form a loop.

Referring to the tenth figure, in practice, the switching button (15) can be a cycle of secondary pressing. For example, when the button (15) is pressed, the value will be displayed on the display screen (20); and then the button is pressed ( 15) When it is next, the value will be switched to the other two display screens (22) and (24) at the same time; the next time, the value will return to the display (20) display.

Accordingly, the present invention moves values between the display screens centered on the vertical axis (S).

Moreover, when one of the buttons is pressed, the function of locking the display screen can be implemented, so that the value can only be displayed on a certain selected display screen. For example, in the fifth figure, when the lock function is executed, the value will only be displayed on the display screen (20). Even if the wrench is rotated to a different angle, the value will not be displayed on other display screens. When one of the buttons is pressed, the lock function can be released, so that the value can be changed to a different display again. The display is displayed.

It can be understood that a switch button can be disposed on each side of the main body (12) to facilitate the user to switch the value to a different display screen.
