Preferably, the trunk attaching surface is made of nontoxic, odorless and antioxidant plastic or rubber materials, and the materials can play a role in reducing the weight of the instrument and preventing skidding. The trunk attaching surface is fixed on the outer side of the ruler rod without the digital display screen, the outer side surface of the trunk attaching surface is arc-shaped, the lower end of the trunk attaching surface is flush with the rotating shaft of the digital display angle ruler, and the middle part of one side of the narrow edge of the arc-shaped structure is widened by about 3cm from the ruler rod. The arc structure is convenient for with the better laminating of trunk, can make digital display angle chi and branch that awaits measuring be in the parallel state after laminating with the trunk moreover, is favorable to improving the measurement accuracy of instrument. The lower extreme of the attached face of trunk and the axis of rotation parallel and level of digital display bevel protractor, what can be convenient with the axis of rotation of digital display bevel protractor and branch the branch point align. The widened part is convenient for an operator to fix the instrument on the corresponding position of the trunk, and the measurement precision of the instrument is not influenced.
Preferably, the laser pointer is a low-power laser transmitter, is powered by the button battery, and emits laser in a linear shape. The laser pointer is fixed at the front end of the outer side of the ruler rod with the digital display screen, is fixed at the center position of the ruler rod, is superposed with the central axis of the ruler body of the digital display angle ruler (namely the central line of the digital display angle sensor shaft), and emits a linear laser line which is vertical to the ruler rod. The laser emitted by the laser direction indicator is controlled by the switch, so that the electricity-saving effect can be achieved, and the problem of hurting people can be prevented.
