Embodiment
The utility model is described in detail with reference to specific embodiment.Following embodiments will be helpful to this area
Technical staff further understands the utility model, but does not limit the utility model in any form.It should be pointed out that to ability
For the those of ordinary skill in domain, without departing from the concept of the premise utility, various modifications and improvements can be made.
These belong to the scope of protection of the utility model.
As shown in Figure 1 to Figure 3, in embodiment, tool change arm provided by the utility model includes rotating part 1, extension 2, receives
Knife portion 3 and elastic fixing structure 4, rotating part 1, extension 2, receive knife portion 3 and be sequentially connected, and receives knife portion 3 and is provided with and holds cutter groove 31,
The slot bottom for holding cutter groove 31 extends along arc direction, and two end faces of tool change arm through-thickness form upper surface and lower end
Face, offers guide groove 22 on the lower face of extension 2；The guide groove 22 extends along 2 length direction of extension, rotating part 1
Circular through hole 11 is provided with geometric center.The elastic fixing structure 4 includes spring 42 and telescopic block 41, and spring 42 is installed on
In guide groove 22, telescopic block 41, spring 42, extension 2 are sequentially connected.
