Furthermore, the terms "first," "second," and "third" are used for descriptive purposes only and should not be construed as indicating or implying relative importance.

[0030] Example 1

[0031] The blocking device disclosed in this utility model will now be described in conjunction with the accompanying drawings, as shown below. Figure 1 Appendix Figure 2 As shown, it includes a support 100, on which a horizontally extending horizontal shaft 200 and a blocking block 300 that rotates and moves around the horizontal shaft 200 are provided. The blocking block 300 can switch between a first state and a second state. In the first state, the blocking block 300 is supported on the support 100 and its length direction L extends horizontally. In the second state, the blocking block 300 is supported on the support 100 and its length direction L extends vertically. At the same time, the blocking block 300 protrudes above the top of the support 100.

[0032] The shape of the support 100 can be set as needed, as shown in the attached figure. Figure 1 Appendix Figure 2 As shown, the support 100 includes a base plate 110, on which at least one vertical plate 120 perpendicular to it is provided, and the horizontal shaft 200 can be connected to the screw hole of the vertical plate 120 by means of a threaded connection.

[0033] Even better, to ensure a stable connection, see attached... Figure 3 - Appendix Figure 5 As shown, the base includes two parallel vertical plates 120 with a gap between them. The horizontal shaft 200 can be a bolt, passing through concentric through holes in the two vertical plates 120 and locked to the two vertical plates by nuts. To ensure a stable connection between the vertical plates 120 and the base plate 110, one vertical plate 120 can be screwed, welded, or integrally formed with the base plate 110. A slot 111 is formed on the base plate 110, and a corresponding locking platform 121 is formed on the lower side of the other vertical plate 120. The locking platform 121 engages with the slot 111, thus limiting the position of the other vertical plate 120. Furthermore, when the two vertical plates 120 are connected together by bolts, the overall structure becomes more stable.

[0034] As attached Figure 1 Appendix Figure 2 As shown, a first limiting plate 130 is provided on the top of the base plate 110 and / or on the inner side of at least one vertical plate 120, located between the two parallel vertical plates 120 with a gap. In the first state, the blocking block 300 lies on the first limiting plate 130 provided on the top of the base plate. Preferably, a second limiting plate 140 is provided on the inner side of at least one of the vertical plates 120, located between the two parallel vertical plates 120 with a gap. The second limiting plate 140 is located on the side of at least one vertical plate 120 closer to the horizontal axis 200. The second limiting plate 140 can better limit the two vertical plates 120 and also limit the blocking block 300. Furthermore, the distance between the first limiting plate 130 and the second limiting plate 140 is greater than the width of the blocking block 300.

[0035] The bolts connecting the two vertical plates 120 pass through the blocking block 300 simultaneously, and the blocking block 300 is positioned between the two vertical plates 120.

[0036] The shape of the blocking block 300 can be designed into different shapes as needed. For example, in one embodiment, the blocking block 300 can be set as an L-shape or a right trapezoid, etc. More preferably, the shape of the blocking block 300 is a cuboid block, and the top corners of the two ends of the cuboid block are rounded.

[0037] As attached Figure 1 Appendix Figure 2 As shown, in order to facilitate switching the state of the blocking block 300, a waist-shaped hole 310 is formed on the blocking block 300. The extension direction of the waist-shaped hole forms an acute angle with the length direction L of the blocking block 300. In the second state, the waist-shaped hole is close to the lower end of the blocking block 300 and the waist-shaped hole is inclined from the lower end of the blocking block to the upper right end.

[0038] As attached Figure 1 - Appendix Figure 4 As shown, to facilitate manual operation of the blocking block 300 for state switching, an operation hole 320 is formed on at least one side of the blocking block 300. The operation hole and the waist-shaped hole are close to both ends of the blocking block 300. At least one of the vertical plates 120 has an operation notch 121 on its top that matches the operation hole on the side of the blocking block 300. The operation notch is semi-circular. In the first state, the operation hole and the operation notch are in the same position, and the diameter of the operation hole is approximately equal to the radius of the operation notch.

[0039] Example 2

[0040] This embodiment discloses a bullseye plate, as shown in the attached figure. Figure 6 Appendix Figure 7 As shown, the device includes a blocker 10 as described above. The blocker 10 is located on at least one side of the bullseye plate 20. In a first state, the top of the blocking block 300 of the blocker 10 is not higher than the bearing surface 201 of the bullseye plate 20. In a second state, the top of the blocking block 300 of the blocker 10 is higher than the bearing surface 201 of the bullseye plate 20. Thus, in the first state, the blocking block 300 does not obstruct the conveying of items on the bullseye plate 20, while in the second state, the blocking block 300 can block the conveying of items on the bullseye plate 20.

[0041] Furthermore, to facilitate manual operation by the operator, the cover plate 202 of the bullseye plate 20 is provided with a clearance hole 203 corresponding to the blocking block 300 of the blocker 10, and a clearance notch 204 corresponding to the operation notch on the vertical plate 120 of the base is provided at the clearance hole 203, and the clearance notch extends to the outside of the operation notch 121.
