[0028] Furthermore, as Figure 1As shown, a signal light 23 is provided on the top of the measuring box body 20, and the signal light 23 is electrically connected to a control circuit board 24, and the control circuit board 24 is electrically connected to the laser transmitter 21 and the laser receiver 22. Specifically, the signal light 23 is used to show that the laser transmitter 21 and the laser receiver 22 are working; when measuring the length, the laser transmitter 21 emits a laser beam, and at this time the laser receiver 22 receives the laser beam, the tool descends, and its tip gradually blocks the laser beam and descends to a set height, and the control circuit board 24 records the distance from when the tip of the tool gradually blocks the laser beam to the set height, which is recorded as the length of the tool; when measuring the diameter, the tool moves and cuts the laser beam, and the control circuit board 24 records the distance from when the tool starts to cut the laser beam to the set height, which is recorded as the diameter of the tool.
[0029] Furthermore, if Figure 4 As shown, the control circuit board 24 is also connected to a connection bus 26 and a power module 25 connected to the connection bus 26. The connection bus 26 includes a power line (not shown in the figure), a signal line (not shown in the figure) and a control line (not shown in the figure).
