At this time, the first connecting rod 1804 and the second connecting rod 1805 rotate synchronously, and the rotation of the first connecting rod 1804 and the second connecting rod 1805 drives the first gear 19 to rotate. The rotation of the first gear 19 drives the second gear 20 to rotate in the opposite direction. When the second gear 20 rotates, it drives the third connecting rod 2101 and the third synchronous wheel 2102 to rotate in the opposite direction, and drives the fourth synchronous wheel 2104 and the fourth connecting rod 2105 to rotate in the opposite direction through the second synchronous belt 2103.

The rotating rod 30 rotates on the rotating shaft 29, thereby cooperating with the rotation of the rotating cylinder 2206 to extend the second extension assembly 9 and the second extension plate 804 on the first extension assembly 8 outward, as shown in FIG. Figure 5 and Figure 8 As shown, the semicircular notch 805 between the second extension plate 804 and the second extension assembly 9 forms a through hole.

The first detection camera 27 detects the upper part of the expansion bolt, and the electric push rod 14 is used to adjust the front and rear positions of the first connecting plate 15 and the second connecting plate 16, so as to subsequently adjust the front and rear positions of the slide plate 23 and the first detection camera 27. The slider 26 and the slide plate 23 are used to adjust the up and down position and the left and right position of the first detection camera 27 respectively. When adjusting the up and down position of the first detection camera 27, the damping block 25 can keep the first detection camera 27 and the slider 26 fixed after being adjusted to the appropriate position. Figure 1 As shown, when the expansion bolts are conveyed to the bottom of the first conveyor belt 3 and the second conveyor belt 7, the second extension plate 804 at the corresponding position will be reset under the action of the elastic band 802, realizing the automatic stop of clamping the expansion bolts and feeding functions.
