When the bonding position of the handle arrives, as the thickness is increased, the handle generates an acting force on the compression wheel 311, the acting force is upward, so that the L-shaped swinging body 41 rotates around the fixed rotating shaft 42, the L-shaped swinging body 41 drives the adjustable rotating shaft 312 to lift, the adjustable rotating shaft 312 drives the compression wheel 311 to lift, the distance between the compression wheel 311 and the roller 321 is increased, and the bonding position of the handle is transmitted; meanwhile, the first fixing pin 4321 is driven to move by the rotation of the L-shaped swinging body 41, so that the distance between the first fixing pin 4321 and the second fixing pin 4322 is increased, the tension spring 4323 connecting the first fixing pin 4321 and the second fixing pin 4322 is prolonged, the tension force generated by the tension spring 4323 acts on the first fixing pin 4321, the L-shaped swinging body 41 has a resetting trend through the first fixing pin 4321, and after the bonding part of the handle passes, the L-shaped swinging body 41 is reset by the tension force of the tension spring 4323; it is achieved that the pitch of the conveying passage formed by the upper conveying mechanism 31 and the lower conveying mechanism 32 is adjusted according to the thickness of the handle passing portion.

When the conveying device stops running, the nut 4332 is loosened, the bolt 4331 is screwed to change the thread length between the positioning block 431 and the L-shaped swinging body 41, the bolt 4331 drives the L-shaped swinging body 41 to rotate, and the L-shaped swinging body 41 drives the adjustable rotating shaft 312 and the pressing wheel 311 thereon to move, so that the distance between the pressing wheel 311 and the roller 321 is adjusted; tightening the nut 4332 prevents the bolt 4331 from loosening, avoiding pitch changes. Taking the connection of the mounting assembly 316 and the upper conveying belt wheel 313 as an example, the fixing screw 3163 is loosened, the mounting rod 3162 is slid, the relative position of the mounting rod 3162 and the mounting seat 3161 is adjusted, the position of the pin 3164 at the end part of the mounting rod 3162 is changed, and therefore the position of the upper conveying belt wheel 313 is changed, the distance between the upper conveying belt wheel 313 and the lower conveying belt wheel 323 is adjusted, and after adjustment, the mounting rod 3162 and the mounting seat 3161 are screwed through the fixing screw 3163. So that the distance of the conveying path formed by the upper and lower conveyors 314, 324 can be manually adjusted by the joint adjustment of the distance adjusting assembly 433 and the mounting assembly 316.
