In order to ensure that the clamping of the carrier tapes 400 with different widths can be realized, the fixing rail clamp 5, the first sliding rail clamp 6, the second sliding rail clamp 7, the fixing clamp 81 and the reciprocating clamp 82 can be arranged, the mounting parts are detachably connected with the corresponding clamping ends, the fixing clamping ends are arranged on the transverse frame rod 4, the rotating rods 95 driven by the adjusting motor are rotationally connected to the fixing clamping ends, the clamping ends are in threaded connection with the outside of the rotating rods 95, two groups of guide rods 96 which are guided and connected in the guide sleeve 97 of the mounting parts are further arranged on the rotating rods, and the relative movement of the two groups of the fixing rail clamp 5, the first sliding rail clamp 6, the second sliding rail clamp 7, the fixing clamp 81 and the reciprocating clamp 82 which are oppositely arranged is controlled through the rotating rods 95.

The clamping end of the reciprocating clip 82 further comprises an opening 821 and a connecting part 822 which are elastically connected in the transverse direction, the clamping opening 91 is arranged at one side of the opening 821, the other side of the clamping opening is provided with a connecting slide slot 823, the end part of the connecting part 822 is provided with a connecting slide block 824 which is transversely and slidably connected in the connecting slide slot 823, two sides of the connecting slide block 824 are provided with abutting springs 825 which are abutted in the connecting slide slot 823, and one side of the fixed clip 81 is also provided with a bump surface 826 which is used for abutting the reciprocating clip 82, so when the screw motor starts to drive the screw 86 to rotate, the driving force of the power equipment is transmitted to the opening 821 through the connecting part 822, namely, when the opening 821 clamps the carrier tape 400 for fixed-length conveying, the process from rest to movement is an elastic process, at the moment, the loss of the power equipment can be reduced, by the bump surface 826 provided on the side of the fixed clip 81, it is meant that when the reciprocating length of the reciprocating clip 82 is the fixed length between the two sets of fixed clips 81, the reciprocating clip 82 will collide with the bump surface 826 of the fixed clip 81 to stop when moving in place, and the collision can ensure accurate fixed length precision of each transmission, but in frequent collisions, sudden suspension occurs in the power equipment, and small continuous movement will also cause a rigid impact force in the transverse direction to the fixed clip, and further frequently cause deformation of the fixed clip 81, thereby affecting the movement precision of the reciprocating clip 82, and by the arrangement of the transverse abutting spring 825, when the reciprocating clip 82 clamps the carrier tape 400 to move to one side and the fixed clip 81 is in collision abutment, at this time, because the connection part 822 rigidly connected with the power equipment is in a resilient connection in the transverse direction with the opening 821, therefore, the power equipment can have a buffering pause time, in which the clamping position of the carrier tape 400 by the opening clamp is unchanged, but the pause delay possibly occurring in the power equipment can drive the connecting part 822 to transversely and continuously move for a certain buffering distance, and the abutting spring 825 is compressed at the moment to eliminate the impact force caused by the sudden pause of the power equipment, so that the dual protection effect on the power equipment and the fixing clamp 81 is achieved, and meanwhile, the fixing clamp 81 is used as a movable limiting block at two ends of the reciprocating movable clamp 82, so that the fixed-length pulling precision is also higher, and the machining alignment errors among different machining procedures can be avoided.

For subsequent maintenance adjustment, the top end of the supporting guide post 300 is fixedly connected with the upper frame plate 100 through a bolt, and the bottom end thereof is welded and fixed on the lower frame plate 200.
