In order to adapt the length of the middle column to lead frames with different widths in the background art, the middle column is divided into a first middle column 5 and a second middle column 6, and the following settings are carried out:

referring to fig. 1, 4 and 5, a plurality of sliding bars 7 are fixed on the first middle column 5 at one side of the second middle column 6 in an annular array, first sliding grooves 8 with the same number as the sliding bars 7 are arranged on the second middle column 6 at one side of the first middle column 5 in an annular array, and the side surfaces of the sliding bars 7 are fan-shaped and can be in other shapes.

The first transmission rod 14 and the second transmission rod 12 are coaxially arranged on one side of the first limiting disc 4 opposite to the second limiting disc 30 respectively, the first transmission rod 14 and the second transmission rod 12 are both square and overlapped in side projection, the first transmission rod 14 is fixedly connected with the first limiting disc 4, the second limiting disc 30 and the second intermediate column 6 jointly form a first rod groove 9, one side of the first intermediate column 5, opposite to the second intermediate column 6, is fixedly embedded with a first motor 11, the output end of the first motor 11 is fixedly connected with a first threaded rod 10, one end of the first threaded rod 10 penetrates through the second intermediate column 6 and extends into the first rod groove 9, a first threaded hole in threaded connection with the first threaded rod 10 is formed in the second intermediate column 6, and a second rod groove 13 for the first threaded rod 10 to rotate is formed in one end of the second transmission rod 12.

Before adjusting the overall length of the center post, it should be noted that the second transmission rod 12 is a fixed arrangement, which is explained below, i.e. the second limiting disk 30 and the second center post 6 can slide relative to the second transmission rod 12.

When the overall length of the middle column is adjusted, the first motor 11 drives the first threaded rod 10 to rotate forwards or reversely, the second middle column 6 and the second limiting disc 30 axially displace under the conditions that the first threaded rod 10 and the first threaded hole are in threaded connection, the sliding strip 7 and the first sliding groove 8 are in sliding connection, the distance between the first limiting disc 4 and the second limiting disc 30 is adjusted to adapt to the furling of lead frame materials with different widths, the threaded connection is of a self-locking structure, and the position can be maintained.

Because the first rod groove 9 slides relative to the second transmission rod 12, the second transmission rod 12 can transmit torque through the first rod groove 9, and the purpose of the square section of the second transmission rod 12 is to ensure that the second transmission rod 12 is always in transmission fit with the first rod groove 9 and has a certain length, the threaded connection of the first threaded hole and the first threaded rod 10 is maintained, and the second transmission rod 12 cannot be hard to rotate the first threaded rod 10, and the hard size requirement is as follows: the second transmission rod 12 is in transmission fit with the first rod groove 9, the section of the second rod groove 13 is circular, and the section diameter of the second rod groove 13 is larger than that of the first threaded rod 10.

In order to solve the problem that the radius of the limiting disc is not adjustable in the background technology, the following settings are carried out:

Secondly, the present invention can adjust the position of each sliding plate 16 relative to the second sliding slot 15, so as to achieve the purpose of extending the radius of the limiting disc (the first limiting disc 4/the second limiting disc 30), which is specifically as follows: before the first electric telescopic rod retracts to the stop plate 20, the sliding plate 16 with the larger gravity in the plurality of sliding plates 16 is placed above, the sliding plate 16 with the larger gravity pushes the sliding disc 18 towards the vertical plate through the connecting rod 17, the gravity is compared less sliding plate 16 and is kept away from riser direction traction sliding disc 18 through connecting rod 17, make whole messenger towards the riser (first riser 2/second riser 3) the power of direction be greater than the power of keeping away from the riser direction after the effort is offset, cause sliding disc 18 to slide towards the riser direction, the tip of second electric telescopic handle 21 offsets with the riser, sliding disc 18 from this through the reaction force that second electric telescopic handle 21 promoted the riser slide on the transfer line, sliding disc 18 drives each sliding plate 16 through each connecting rod 17 and moves towards the direction of keeping away from second sliding tray 15, the radius up to sliding plate 16 surface to spacing dish axis position satisfies the needs.
