The material blocking part 12 is movably arranged relative to the discharge hole 33.

The material blocking member 12 is used for blocking the discharge hole 33 to block the screw in the feeding channel 32 from entering the batch head channel 31 from the discharge hole 33. In this embodiment, the blocking member 12 is a baffle, and the blocking member 12 is moved to open or close the discharge hole 33. Specifically, a guide groove or a slide rail may be disposed on the inner wall of the batch head channel 31, so that the baffle slides in the guide groove or the slide rail to limit the movement track of the baffle, thereby stabilizing the movement direction of the baffle.

The linkage member 13 is rotatably mounted on the inner wall of the batch head channel 31, the linkage member 13 includes a first linkage end 131 and a second linkage end 132, the first linkage end 131 is movably connected to the material blocking member 12, the second linkage end 132 is located on the lifting path of the convex ring 11, and the lifting path of the convex ring 11 includes an open position and a closed position. When the convex ring 11 is at the closing position, the linkage piece 13 is separated from the convex ring 11, and the material blocking piece 12 closes the discharge hole 33; when the convex ring 11 is in the opening position, the linkage piece 13 is pushed by the convex ring 11 to rotate, and the material blocking piece 12 opens the material outlet 33.

The linkage part 13 is used for controlling the material blocking part 12 to move, and the first linkage end 131 and the second linkage end 132 are respectively located at two ends of the linkage part 13; specifically, when the linkage 13 rotates, the first linkage end 131 and the second linkage end 132 both move in opposite directions. The first linkage end 131 can be hinged to the material blocking part 12, and can also be linked to the material blocking part 12 to move, so that the first linkage end 131 drives the material blocking part 12 to open or close the material outlet 33 when moving. The second linkage end 132 is contradicted with the convex ring 11 in the descending process of the convex ring 11, the convex ring 11 pushes the second linkage end 132 to move along with the convex ring 11 when being contradicted with the second linkage end 132, so the second linkage end 132 drives the first linkage end 131 to move towards the direction opposite to the convex ring 11, and the material blocking part 12 is driven to gradually open the material outlet 33 until the convex ring 11 is separated from the second linkage end 132, and the material blocking part 12 resets under the self gravity thereof to close the material outlet 33.

In this embodiment, the material blocking member 12 blocks the screws in the feeding channel 32, so that the screws in the feeding channel 32 can enter the batch head channel 31 only when the material blocking member 12 is opened; the convex ring 11 is sleeved on the batch head 21, the convex ring 11 ascends and descends along with the batch head 21, when the convex ring 11 descends to be close to the linkage piece 13 and abuts against the second linkage end 132, at this time, the convex ring 11 is located at the opening position, the convex ring 11 pushes the linkage piece 13 to rotate, so as to link the first linkage end 131 to drive the material blocking piece 12 to move towards the direction opposite to the ascending and descending direction of the convex ring 11, so as to open the discharge port 33, and a screw enters the batch head channel 31 from the discharge port 33; the rear convex ring 11 continuously descends along with the screwdriver bit 21 and is separated from the second linkage end 132, at the moment, the convex ring 11 is located at the closing position, the material blocking member 12 resets under the action of the self gravity to close the discharge hole 33, and thus, screws of the discharge hole 33 are intercepted; because the batch head 21 is fast to rise and fall, so the time of conflict between the convex ring 11 and the second linkage end 132 is short, the discharge port 33 is opened, after a screw enters the batch head channel 31, the linkage part 13 is reset quickly to intercept the next screw extending out of the discharge port 33, so that the problem that the screw in the feeding channel 32 partially extends out of the channel and contacts with the electric batch 2 is solved, the electric batch 2 is prevented from being abraded in the rotating or lifting process of the electric batch 2, and the service life of the electric batch 2 is prolonged.

In the first embodiment of the transmission mechanism 1, as shown in fig. 2 to 4, the transmission mechanism 1 further includes a first insection 133, a second insection 111 and a third insection 121; the first insection 133 is positioned at the outer edge of the linkage piece 13, and the linkage piece 13 is a rotating disc; the second insections 111 are positioned on the outer edge surface of the convex ring 11 and are matched with the first insections 133; the third insection 121 is located at one end of the blocking member 12 close to the linking member 13 and is matched with the first insection 133.
