[0050] Since the replacement frame 17 is arranged in a "U"-shaped frame structure, which is divided into a transverse frame body and two longitudinal frame bodies in the front and back. The lower ends of the two longitudinal frame bodies in the replacement frame 17 are both horizontally provided with an integrated cross plate portion 1701, and a through groove is opened on the cross plate portion 1701. Also, since roller members 1901 are arranged on the front and back sides of the upper section of the sleeve frame 19, the sleeve frame 19 is arranged in the gap between the two cross plate portions 1701, and the roller members 1901 movably penetrate through the groove of the cross plate portion 1701, and the edge of the groove of the cross plate portion 1701 is movably clamped in the cavity of the roller members 1901.

After the exchange frame 17 is placed, two of the positioning plates are movably clamped in the limit slide grooves on both sides of the sub-shell seat 16, and the lower sections of the two clamping claw plates 8 are movably inserted in the frame cavity of the exchange frame 17, so that the exchange frame 17 is in a The active state is positioned on the secondary housing seat 16, and because the telescopic electromagnet 18 is installed in the seat cavity of the secondary housing seat 16 by bolts after being installed, it is arranged in a vertical downward state, wherein the output end is plugged and connected to the middle of the horizontal frame body of the exchange frame 17 by bolts, the telescopic electromagnet 18 is started to operate, so that the exchange frame 17 slides directly under the secondary housing seat 16, and the sleeve frame 19 is placed in the gap between the two horizontal plate parts 1701 after being installed, and through the clamping action between the horizontal plate part 1701 and the roller part 1901, the exchange frame 17 slides and pushes and pulls the sleeve frame 19 to move synchronously;

[0052] After the sleeve rack 19 is installed, its upper section is movably sleeved on the lower section of the clamping claw plate 8, and is positioned in an active state, and its lower section is movably clamped on the tubular claw body of the claw head member 14, and the sleeve rack 19 is driven to slide on the lower section of the clamping claw plate 8;

[0053] Since the lower plate body of the clamping claw plate 8 is provided with two claw head members 14, a spiral groove 1401 is opened on the tubular claw body of the claw head member 14, and the spiral groove 1401 is set in a through state, and its spiral angle is forty-five degrees, and the spiral angles of the spiral grooves 1401 on the two claw head members 14 are set in opposite directions, and since the front and rear sides of the lower section of the sleeve rack 19 are both provided with pin column members 1902, the pin column member 1902 is inserted and threadedly fixed to the frame wall of the sleeve rack 19 after being installed, and is set in a vertical state, and it is movably inserted in the spiral groove 1401.

[0055] Since a torsion spring 15 is installed at the connection between the claw head member 14 and the circular shaft column 801, the torsion spring 15 is movably mounted on the circular shaft column 801 after being installed, one end of which is clamped on the circular shaft column 801, and the other end of which is clamped on the tubular claw body of the claw head member 14. Since the lower section of the claw head member 14 is arranged in a plate-like structure, a rubber pad is fixedly mounted on the plate-like claw body of the lower section.

The return spring 7 is symmetrically arranged about the horizontal center axis of the linkage frame 6. After the return spring 7 is installed, one end of the return spring 7 is movably inserted in the spring bin of the linkage frame 6 and pressed against the bin wall, and the other end of the return spring 7 is inserted in the spring bin of the main housing seat 5 and pressed against the bin wall. After the linkage frame 6 slides, the return spring 7 is squeezed and elastically deformed, and then reset by the elastic deformation of the return spring 7, which assists the reset sliding of the linkage frame 6;

[0060] Since the length of the transmission shaft 11 is greater than the maximum sliding distance of the transmission tube 12, when the linkage frame 6 is driven to slide, the sliding directions of the two linkage frames 6 and the clamping claw plates 8 are opposite, and the transmission tube 12 slides on the transmission shaft 11, that is, the sliding adjustment of the clamping claw plates 8 is not affected, and the clamping operation of the electronic components is performed by driving the claw head 14 to move in the opposite direction through the clamping claw plates 8;
