[0046] In an alternative embodiment of the present utility model, a power module is fixedly arranged inside the first end of the axe handle 1. The power module is electrically connected to the sensor 7, the buzzer and the positioning module to supply power to the sensor 7, the buzzer and the positioning module.
[0047] In this embodiment, a power module is also built into the non-hollow structure at the first end of the axe handle 1. This power module uses small and light batteries such as dry batteries, lithium batteries, button batteries, etc. as the power supply.
