Reinforcing bar binding device

A reinforcing bar binding device comprising:

• a binding section configured to bind a reinforcing bar;
• a holding section configured to hold the binding section;
• a lifting section configured to move the holding section in a vertical direction with respect to a body section of the reinforcing bar binding device;
• and
• an elastic section configured to attenuate a movement speed of the holding section in a lowering direction,
• wherein the elastic section attenuates the movement speed of the holding section in the lowering direction only in a state where the binding section abuts against the reinforcing bar.

A reinforcing bar binding device comprising:

• a binding section configured to bind a reinforcing bar;
• a holding section configured to hold the binding section;
• a connecting section connected to the holding section;
• and
• a control section configured to control movement of the holding section and the binding section, relative to a body section of the reinforcing bar binding device, by driving the connecting section,
• wherein the connecting section includes an engaging section configured to engage with the holding section, and
• wherein the control section is configured to perform:
• a first operation of lowering moving both the holding section and the engaging section in a first movement direction while the holding section and the engaging section are engaged, thereby causing the binding section to contact the reinforcing bar;
• and
• a second operation of moving the engaging section relative to the holding section to release engagement between the holding section and the engaging section in a state where the binding section abuts against the reinforcing bar.

A reinforcing bar binding device comprising:

• a binding section configured to bind a reinforcing bar;
• a holding section configured to hold the binding section;
• a lifting section configured to raise and lower the holding section with respect to a body section;
• and
• an elastic section configured to reduce a movement speed of the holding section in a lowering direction,
• wherein the elastic section reduces the movement speed of the holding section in the lowering direction only in a state where the binding section abuts against the reinforcing bar.
