[0034] The side of the driving fixed seat 124 and the driven fixed seat 134 for mounting the feeding device is defined as the front side, the beam 18 is arranged on the opposite side for connecting the driving fixed seat 124 and the driven fixed seat 134, three groups of mounting holes 21 are arranged on the driving fixed seat 124 and the driven fixed seat 134 respectively, a rotating shaft 20 is arranged in one group of mounting holes on the driving fixed seat and one group of mounting holes on the driven fixed seat respectively, the two ends of the beam 18 are provided with limiting grooves 182, bearings 19 are arranged in the limiting grooves 182, and the two groups of rotating shafts 20 are connected to the bearings 19 and meet the requirement of the overall inclination of the beam, that is, the rotating shafts are not installed in the mounting holes in the same horizontal position.

[0035] Preferably, the limiting groove 182 comprises a rectangular part in the middle and arc-shaped parts extending along the two ends of the rectangular part, the arc-shaped parts are semicircular to make the limiting groove look like a runway, the bearing 19 can slide in the range of the limiting groove, the middle position of the beam is provided with a connecting hole 181 for connecting the second transmission member 103, and the connecting rod shaft as the second transmission member 103 and the connecting hole 181 constitute a rotation-stopping connection.

[0038] Working principle: in practical application, the pipeline needs to move from top to bottom, and initially the pipeline is manually inserted from the upper guide hole 113 into the lower guide hole. When the motor rotates, the second transmission shaft 141 is driven to rotate through the meshing of the first transmission member 102 and the third transmission member 142. From the front direction, the driving synchronous belt 123 always rotates counterclockwise, and the extrusion of the driven synchronous belt 133 drives the pipeline to move downward. The first one-way bearing 143 is used to prevent the driving synchronous belt from reversing. At this time, the second transmission member 103 does not rotate due to the action of the second one-way bearing 105. When the motor reverses, the second transmission member 103 drives the cross beam 18 to rotate. Since the cross beam 18 is inclined, the driving fixed seat 124 and the driven fixed seat 134 are separated to the two sides under the cooperation of the bearing 19 and the limiting groove 182, and at the same time the spring 152 in the two side reset assemblies is compressed. The first transmission member 102 and the third transmission member 142 are also separated. When the pipeline is inserted again, the motor rotates forward, the compressed springs 152 on both sides are reset, driving the driving fixed seat 124 and the driven fixed seat 134 to move to the middle, and the first transmission member 102 and the third transmission member 142 are meshed again.
