When the position of the tension roller needs to be adjusted, the adjustment lever 1202 is rotated to move the adjustment lever 1202 relative to the fixed base 1204. When the adjusting rod 1202 is screwed forward relative to the fixed seat 1204, the end of the adjusting rod 1202 pushes the pressing section 1201 forward along the first slideway 1203 by pressing action, and then drives the tensioning roller 4 to move forward, so that the belt 2 is tensioned; when the adjusting rod 1202 is rotated out reversely relative to the fixing seat 1204, under the action of the self-gravity and the contracting elastic force of the belt 2, the tensioning roller 4 drives the pressing section 1201 to slide backwards along the first slideway 1203, so as to keep the pressing section 1201 in contact with the adjusting rod 1202, and reduce the tightness of the belt 2. Specifically, the adjusting assemblies 12 are provided with two groups and are respectively arranged on two sides of the telescopic conveying device, and the two groups of adjusting assemblies 12 are synchronously adjusted when the telescopic conveying device is used.
