[0026] like Figure 1-Figure 4As shown, an adjustment mechanism 3 is provided on the support seat 202, and the adjustment mechanism 3 includes a driving shell 301, and the driving shell 301 is rotatably connected to the outside of the transmission gear 205, and the outside of the driving shell 301 is rotatably connected to the first connecting rod 302 and the second connecting rod 306.

At this time, the first connecting rod 302 drives the transmission gear 205 outward under the elastic drive of the buffer spring 308 and keeps the transmission gear 205 meshed with the rack 206. When the driving block 305 rises, due to the restriction of the upper rack 206, the rise of the driving housing 301 is blocked, and the second connecting rod 306 stretches the buffer spring 308 and drives the driving rod 204 inward under the action of the inward component of the connecting rod, thereby adjusting the position of the drilling needle 208. When performing the drilling operation, the motor 209 is started and drives the toothed ring 211 on the outside of the driving sleeve 203 to rotate through the driving gear 210. The driving sleeve 203 rotates accordingly and drives all the meshed transmission gears 205 and the driving rod 204 to rotate through the inner rack 206, thereby realizing the simultaneous drilling operation of multiple holes.
