This may be achieved by a unidirectional bearing connection in the respective direction between the drive pulley 204 and the output shaft 205 of the welding-work motor.
The subassembly is fixed in butt fusion work for the fixed structure of portable baling press bottom, and the upper surface sets up fixed friction structure 4, butt fusion work piece 33 and the cooperation of fixed friction structure 4 make the joint of packing area generate heat the butt fusion through the friction.
In operation, when the handle 6 is lifted up after the previous strapping band joint is welded, the handle assembly is rotated, the pawl 61 automatically releases the unidirectional locking of the tension device of the hand baler by rotating, at the same time, the gear 62 drives the gear 72 on the swing link 7 to rotate, the swing link 7 is pressed down, and the connecting part 71 at the end of the swing link also acts downwards on the first input portion 11.

When the first input portion 11 is acted upon, the entire intermediate coupling member 1 is rotated in the first direction (counterclockwise in fig. 5), and the second input portion 12 is thereby rotated to the position shown in fig. 5, but since the welding work motor 200 and the transmission mechanism 202 are in a one-way transmission connection relationship, the output member 201 is engaged with the second input portion 12 at this time, but the transmission mechanism is not rotated in the reverse direction. When the locking mechanism connecting portion 13 is rotated in the first direction, the rotation axis between the inclined locking mechanism and the locking mechanism connecting portion 13 is also rotated to the outside of the second side of the plane, thereby releasing the locking, and the mounting bracket 31 can be rotated and lifted up to be in the state of fig. 5. The well-bonded packing belt can be removed, and meanwhile, the packing belt which needs to be packed and welded is placed into the bag.
After the strapping band is tensioned, the welding operation motor 200 is signaled to start operation, so that the output part 201 is driven to rotate by the motor, the second input part 12 is driven to rotate in the second direction, and thus the whole intermediate connecting part 1 is rotated in the second direction, the rotation axis between the inclined locking structure and the locking structure connecting part 13 also rotates to the outside of the first side of the plane to realize locking, in this state, the pressure spring 22 enables the intermediate connecting part 1 to keep the trend of rotating in the second rotation direction, so that the stopper 14 is pressed against the gear 101 of the limiting structure, and the mounting frame is pressed down to the welding operation angle under the action of the pressure spring 22, thereby realizing locking.

At this time, since the sector gear has been disengaged from the output member 201 (see fig. 6) and is held by the locking structure, the intermediate coupling member 1 is maintained in the normal operating state without being interfered.
After the melting is finished, the handle is lifted again, and the process is repeated.
