Specific embodiment
For the technical solution of the utility model and its course of work is further described, in conjunction with Figure of description, this is practical new
The specific embodiment of type is as follows:
As depicted in figs. 1 and 2, the utility model discloses a kind of electric screw driver buffer, described device by
Spring guide pillar mechanism 1, screwdriver connecting plate 2 and robot connecting plate 3 form.
As shown in Figure 3 and Figure 4, the spring guide pillar mechanism 1 is made of guide post 101, spring 102 and guide column sleeve 103.Its
In, the top of the guide post 101 is equipped with limit outer；The guide column sleeve 103 is sleeved on the lower section of guide post 101 and along guide post 101
Linear movement, the two sides of the bottom of guide column sleeve 103 are equipped with symmetrical otic placode, are provided with connecting hole on otic placode；The spring 102 is sleeved on
