Detailed Description

In order to make the technical means, creation features, achievement purposes and functions of the present invention easy to understand, the present invention is further described below with reference to the following embodiments.

Referring to fig. 1-5, the present invention provides a technical solution: the utility model provides a carving machine tool bit structure that protection nature is good, including tool bit 4, installation head 3 and mount pad 2, tool bit 4 is fixed in installation head 3 bottom, installation head 3 is installed in mount pad 2, the mounting groove has been seted up in the mount pad 2, be provided with the internal thread in the mounting groove, 3 annular side of installation head is provided with the external screw thread, installation head 3 is connected with mount pad 2 through the screw thread, 3 tops of installation head are fixed with

ratchet

6, 2 inside upside rotations of mount pad are connected with dwang 5, dwang 5 bottoms are fixed with

spacing shifting block

7, 7 inboard spacing blocks 8 that are fixed with of spacing shifting block, stopper 8 is fixed on mount pad 2.

The limit shifting block 7 is matched with the ratchet wheel 6. The rotating rod 5 extends out of the top of the mounting seat 2. The connection part of the mounting seat 2, the rotating rod 5 and the limiting shifting block 7 is provided with a containing groove 21, and the specification of the containing groove 21 is larger than that of the limiting shifting block 7.
