Specific embodiment：
The present invention is further illustrated below in conjunction with the accompanying drawings.
As shown in Figure 1, a kind of device of quick assembling liquid nitrogen frozen roller pin of the present invention, including locating piece 1 and limit base
2, locating piece 1 is fixedly connected on the top of limit base 2, and 4 elastic bearing of limit shaft is in limit base 2, and the upper end of limit shaft 4 is worn
It crosses locating piece 1 and stretches out outside locating piece 1.Elastic bearing has positioning pin 3 on the side wall of limit base 2, one end of the positioning pin 3 with
The side wall of limit shaft 4 is inconsistent.
The first limit hole 21 and the second limit hole 11,21 He of the first limit hole are respectively equipped on limit base 2 and locating piece 1
Second limit hole 11 connects, and by 8 elastic bearing of the first spring in the first limit hole 21,4 upper end of limit shaft leads to limit shaft 4
The second limit hole 11 is crossed to stretch out outside locating piece 1.
Location hole 22 is equipped on the side wall of limit base 2, which connects with the first limit hole 21, and with first
21 perpendicular setting of limit hole, 3 elastic bearing of positioning pin is in location hole 22.
Positioning pin 3 in the present invention is in location hole 22 by 7 elastic bearing of an elastic mechanism, which wraps
