[0041] In summary, when using the overall equipment: the user can pull the handwheel 9 outward to extend the connecting spring 8, causing the locking pin 13 on the locking ring 12 to disengage from the locking groove 11. At this time, the handwheel 9 can be rotated, which in turn drives the worm gear 5 to rotate through the pull rod 7, thereby causing the turbine 4 to drive the connecting block 14 to rotate, thus adjusting the angle of the device. When the tool 17 needs to be replaced, the fastening nut 22 can be removed first to take the pin 21 out of the through hole 20. At this time, the insert rod 18 and the motor 16 can be separated to disassemble the tool 17 for easy replacement. Furthermore, by setting the positioning block 23 and the positioning groove 24, relative rotation between the insert rod 18 and the motor 16 can be prevented, facilitating subsequent processing of parts. The user can also periodically disassemble the sealing block 31 through the internal hexagonal slot, and then add lubricating oil to the oil storage chamber 28 through the oil filling port 30.
