As shown in fig. 1 to 4, an embodiment of the present invention proposes a stopper 10 including a base case 100, a first fixing shaft 210, a blocking block 300, a second fixing shaft 220, a first support plate 410, a second support plate 420, and a driving mechanism 600. The base cartridge 100 is provided with a receiving chamber 111 and a blocking hole 121 communicating with the receiving chamber 111. The first fixing shaft 210 is fixedly coupled with the base case 100. The blocking piece 300 is disposed through the first fixing shaft 210 and is used for rotating around the first fixing shaft 210. The second fixing shaft 220 is fixedly coupled with the base case 100. The first support plate 410 is disposed in the accommodating cavity 111, and the first support plate 410 is disposed on the second fixed shaft 220 in a penetrating manner and is used for rotating around the second fixed shaft 220. The second support plate 420 is disposed in the accommodating cavity 111, the blocking block 300 and the first support plate 410 are rotatably connected with the second support plate 420, the rotation axis between the blocking block 300 and the second support plate 420 is a first movable shaft 510, and the rotation axis between the first support plate 410 and the second support plate 420 is a second movable shaft 520. The driving mechanism 600 is used to drive the second support plate 420 to move or rotate until the blocking block 300 is at the first position, when the blocking block 300 is at the first position, the blocking block 300 passes through the blocking hole 121 and protrudes out of the base box 100, and the first fixing shaft 210 and the first fixing shaft 510 are arranged in parallel along the first direction, and the first fixing shaft 510, the second fixing shaft 520 and the second fixing shaft 220 are arranged in parallel along the second direction, and the first direction is perpendicular to the second direction (note that "perpendicular" herein does not only mean absolute perpendicular, but also allows a certain error to exist, as long as the same effect can be achieved); the driving mechanism 600 is further configured to drive the second support plate 420 to move or rotate until the blocking block 300 rotates to the second position, where the blocking block is received in the receiving cavity 111.
When the stopper 10 is in the blocking state, the driving mechanism 600 drives the second supporting plate 420 to rotate or move until the blocking block 300 protrudes from the blocking hole 121, and the blocking block 300 is used for contacting the moving conveyed object 40 and stopping the movement of the conveyed object 40 (see fig. 6). In addition, at this time, the direction in which the first fixing shaft 210 and the first fixing shaft 510 are juxtaposed is perpendicular to the direction in which the first fixing shaft 510, the second fixing shaft 520 and the second fixing shaft 220 are juxtaposed, and when the blocking piece 300 is impacted by the conveyed object 40, the blocking piece 300 will rotate circumferentially around the first fixing shaft 210, and since the tangential direction of a certain point on the circumference is perpendicular to the radial direction of the circumference at the point, the arrangement direction of the first fixing shaft 510, the second fixing shaft 520 and the second fixing shaft 220 is on the same line with the tangential direction of the circumferential force exerted by the blocking piece 300, that is, the circumferential force exerted by the blocking piece 300 directly acts on the second fixing shaft 220 along the second direction, and the arrangement makes the circumferential force exerted by the blocking piece 300 have no component in the first direction, so that the blocking piece 300 can be prevented from being transferred into the accommodating cavity 111 to fail due to the excessive impact force exerted. Therefore, the stopper 10 has better blocking performance and can bear larger impact force, and can timely stop the conveyed object from moving and has longer service life. When the stopper 10 is in the non-blocking state, the blocking block 300 is rotated to the first position, i.e. is received in the receiving chamber, so that the movement of the conveyed object 40 is not blocked.
Specifically, as shown in fig. 1 and 5, the base cartridge 100 includes a base body 110, a first shield 120, and a second shield 130. The base body 110 is provided with a containing cavity 111, the first guard plate 120 and the second guard plate are connected with the base body 110 and cover the cavity wall of the containing cavity 111, and the first guard plate is provided with a blocking hole 121.

This arrangement is advantageous in forming a stable support for the blocking piece 300 in the first position, so that the blocking piece 300 has a good impact-bearing capacity.
As shown in fig. 1 and 5, the base body 110 is provided with two pin holes 117 disposed opposite to each other, and the limiting pin 810 passes through the two pin holes 117 and is fixedly connected with the walls of the two pin holes 117.
Specifically, as shown in fig. 2 and 4, the projections of the first movable shaft 510, the second movable shaft 520, and the fourth movable shaft 540 on the second support plate are arranged in a triangle. The stress point of the fourth movable shaft 540 is not located on the connection line of the stress points of the first movable shaft 510 and the second movable shaft 520, which can protect the fourth movable shaft 540 better due to the triangle stability principle, and can avoid the rigidity of the second support plate 420 from being reduced due to the fact that the penetrating hole of the fourth movable shaft 540 is drilled on the connection line of the stress points of the first movable shaft 510 and the second movable shaft 520.
Further, the fourth movable shaft 540 is provided at a side of the plane defined by the first movable shaft 510 and the second movable shaft 520 opposite to the first fixed shaft 210. The blocking piece 300 is provided with an avoidance slope 320, and the avoidance slope 320 is arranged opposite to the blocking plane 310. The arrangement is such that the stop block 300 does not collide with the wall of the stop hole 121 when the avoidance ramp 320 of the stop block 300 is rotated downward from the first position to the second position.
Optionally, the driving mechanism 600 is an air cylinder, the cylinder barrel 610 of the air cylinder is fixedly connected with the base box 100, and the push rod 620 of the air cylinder is rotatably connected with the toggle plate 700.
