[0028] During operation, when the movable seat 3 needs to stop sliding on the guide rail 2, it will not stop immediately due to inertia, and the items on the movable seat 3 will continue to be transported, resulting in inaccurate positioning, affecting the subsequent use effect. In order to solve the problem that the movable seat 3 is inconvenient to stop, when the movable seat 3 stops, the driving mechanism is controlled by a computer program to start the driving mechanism, and the connected rack 54 is driven to move by the driving mechanism, and the rack 54 drives the gear 53 to rotate, and the gear 53 drives another rack 54 to move, so that the two racks 54 move at the same time, and the rack 54 drives the pressure block 55 to move, and when the pressure block 55 moves into the socket 59, the clamping generates friction, and the friction force stops the limit seat 5, and the fixed seat 4 and the movable seat 3 are stopped by the limit seat 5, thereby realizing the function of emergency stopping the movable seat 3.

[0029] Further, such as Figure 3 and Figure 4 As shown, the end of the pressing block 55 close to the guide rail 2 is provided with anti-skid grooves; the socket 59 is fixed with an anti-skid pad 510; the anti-skid grooves and the anti-skid pad 510 are used to increase the friction between the pressing block 55 and the socket 59.

By providing anti-slip grooves and anti-slip pads 510, when the pressure block 55 and the socket 59 are plugged together, the anti-slip grooves are in contact with the anti-slip pads 510, thereby increasing the friction force and reducing damage.

[0036] During operation, the movable seat 3 and the fixed seat 4 need to be connected together. By pressing the plug block 42, the plug block 42 moves to both sides, the spring 47 is stretched, and the top of the plug block 42 is inserted into the slot of the movable seat 3, so that the movable seat 3 and the fixed seat 4 are connected together; when the movable seat 3 needs to be disassembled, the pressure on the plug block 42 is released, and under the action of the spring 47, the plug block 42 moves toward the center, and the top of the plug block 42 leaves the slot of the movable seat 3, so that the movable seat 3 and the fixed seat 4 are separated, and the movable seat 3 can be disassembled.

[0037] Further, such as Figure 5 As shown, a threaded rod 45 is threadedly connected to the fixed seat 4; an elliptical block 44 is fixedly connected to the outer side of the threaded rod 45; the elliptical block 44 is arranged in the movable cavity 41; the top end of the threaded rod 45 passes through the conveyor belt 11 and is threadedly connected to the movable seat 3; a nut 46 is fixedly connected to the top of the threaded rod 45.

[0038] During operation, when the plug block 42 needs to be driven, the nut 46 is rotated, and the nut 46 drives the threaded rod 45 to rotate, and the threaded rod 45 drives the elliptical block 44 to rotate. The bottom of the threaded rod 45 rotates into the threaded groove at the bottom of the fixing seat 4. When the elliptical block 44 rotates until the major semi-axis contacts the plug block 42, the plug block 42 can be pushed and pressed to both sides until the plug block 42 enters the slot; when disassembly is required, the nut 46 is rotated in the opposite direction to rotate the elliptical block 44 90 degrees.

[0043] Working principle: when the moving seat 3 needs to stop sliding on the guide rail 2, it will not stop immediately due to inertia, and the items on the moving seat 3 will continue to be transported, resulting in inaccurate positioning, affecting the subsequent use effect. In order to solve the problem that the moving seat 3 is inconvenient to stop, when the moving seat 3 stops, the electric push rod 58 is controlled by a computer program, and the electric push rod 58 drives the connecting plate to move, and the connecting plate drives the connected rack 54 to move, and the rack 54 drives the gear 53 to rotate, and the gear 53 drives another rack 54 to move, so that the two racks 54 move at the same time, and the rack 54 drives the pressure block 55 to move, and the pressure block 55 moves into the socket 59, and the friction force is generated by clamping, and the limit seat 5 is paused by the friction force, and the fixed seat 4 and the moving seat 3 are paused by the limit seat 5, thereby realizing the function of emergency stopping the moving seat 3; when it is needed To connect the movable seat 3 with the fixed seat 4, the nut 46 is rotated, and the nut 46 drives the threaded rod 45 to rotate, and the threaded rod 45 drives the elliptical block 44 to rotate, and the bottom of the threaded rod 45 rotates into the threaded groove at the bottom of the fixed seat 4. When the elliptical block 44 rotates until the major semi-axis contacts the plug block 42, the plug block 42 moves to both sides by pressing the plug block 42, and the spring 47 is stretched, and the top of the plug block 42 is inserted into the slot of the movable seat 3, so that the movable seat 3 and the fixed seat 4 are connected together; when the movable seat 3 needs to be disassembled, the nut 46 is rotated in the opposite direction, and the elliptical block 44 is rotated 90 degrees to release the pressure on the plug block 42. Under the action of the spring 47, the plug block 42 moves toward the center, and the top of the plug block 42 leaves the slot of the movable seat 3, so that the movable seat 3 is separated from the fixed seat 4, and the movable seat 3 can be disassembled.
