[0025] Working principle: When it is necessary to inspect the strut body 6 during operation, first, multiple groups of strut bodies 6 are put into the inside through the L-shaped feeding bin 22 at the top of the feeding box 21 in turn. After the multiple groups of strut bodies 6 enter the feeding box 21, they can be offset to both sides through the inner inclined surface 2132 opened on the front and rear walls of the internal trapezoidal block 213. Then, part of the strut body 6 is laid flush on the inner bottom end of the feeding box 21 under the limit of the bottom semi-arc surface 2131, and the central single group of strut bodies 6 can fall in the lower feed 212 to the upper feeding port 3111 at the top of the discharging cylinder 311, and then fall into the U-shaped groove 3122 opened on the top of the feeding roller 312 perpendicular to the upper feeding port 3111, and then power is turned on to start the servo motor 411 to rotate and drive the threaded rod 41 2 is rotated, and the rotation of the threaded rod 412 can drive the long barrel nut 413 of the front threaded sleeve to move backward. When the long barrel nut 413 moves backward, it can drive the cross plate 414 fixed at the top to move. When the cross plate 414 moves, the two sets of sliding sleeves 421 can move in the sliding rod to move smoothly. When the cross plate 414 and the semicircular block 415 fixed at the top move to the rear side, the rotation of the threaded rod 412 can drive the belt group 71 at the rear end to rotate. The rotation of the belt group 71 can drive the first transmission rod 72 at the top to rotate. The rotation of the first transmission rod 72 can enable the longitudinal bevel gear 73 fixed at the front end to engage the transverse bevel gear 74 on the right side to rotate. The rotation of the transverse bevel gear 74 can drive the fixed second transmission rod 75 to limit The fixed bearing 76 inside the plate 77 rotates, and the second transmission rod 75 rotates to rotate the sprocket group 78 to drive the rotating shaft 3121 in the center of the picking roller 312 to rotate. The rotation of the rotating shaft 3121 can drive the picking roller 312 to rotate downward. The picking roller 312 rotates to rotate the support rod body 6 filled in the U-shaped groove 3122 downward and drop it through the drop-down port 3122 at the bottom to the square inner groove 511 opened inside the two sets of support platforms 5. Then the servo motor 411 is driven in the reverse direction to drive the threaded rod 412 to rotate in the opposite direction, thereby driving the semicircular block 415 at the top of the cross plate 414 to move forward to the maximum distance at the front end. When the semicircular block 415 pushes the center of the support rod body 6 to move forward, the maximum bending threshold will not break, and the threaded rod 4 When the first transmission rod 72 is reversed, the first transmission rod 72 can drive the fixed longitudinal bevel gear 73 to engage the transverse bevel gear 74 to reverse, and the transverse bevel gear 74 can drive the second transmission rod 75 to reverse, and then drive the sprocket group 78 to reversely drive the rotating shaft 3121 on the right side of the feeding roller 312 to reverse, so as to facilitate driving the rotating shaft 3121 to drive the feeding roller 312 to return to the bottom end of the feeding box 21. When the U-shaped groove 3122 at the top of the feeding roller 312 rotates to the top of the discharging cylinder 311 and is perpendicular to the upper feeding port 3111, a group of support rod bodies 6 at the bottom center of the feeding box 21 can be filled into the U-shaped groove 3122.After the bottom side support rod body 6 is inspected, the support rod body 6 is manually pushed to the left to be removed through the circular hole 512 opened on the left end support platform 5 and then taken out through the discharge port 121 opened on the support frame 12. This operation can be repeated and the operation is completed.
