[0033] When this structure is adopted, the worker aligns the lower end of the inductor skeleton with the snap-in position 11, then snaps the lower end of the skeleton into the clamping position 201, and starts the driving structure 24. After the driving structure 24 is started, it drives the left clamping member 22 and the right clamping member 23 to move closer to each other relative to the connecting member 21. After moving closer to each other, the left clamping member 22 and the right clamping member 23 cooperate to form the clamping position 201, and the lower end of the skeleton is clamped.

In addition, since multiple snap-in positions 11 and multiple clamping devices 2 are provided on the connecting frame 1, workers can realize assembly line operations, thereby improving processing efficiency.

[0034] like Figures 4 to 5 As shown, a mounting seat 3 is connected to the lower side of the connecting member 21, and the driving structure 24 includes a first slider 241 and a second slider 242 which are slidably connected to the connecting member 21, and the first slider 241 and the second slider 242 are located on both sides of the connecting frame 1, the left clamping member 22 is connected to the first slider 241, and the right clamping member 23 is connected to the second slider 242. A synchronization component 243 is provided between the mounting seat 3 and the first slider 241 and the second slider 242, which can make the first slider 241 and the second slider 242 move synchronously closer to each other or move synchronously away from each other, and a driving motor 244 which can drive the synchronization component 243 to move is also connected to the mounting seat 3.

When the connecting block 2433 moves, it drives the lower end of the first rotating member 2431 to move, and the middle part of the first rotating member 2431 rotates relative to the connecting member 21. The upper end of the first rotating member 2431 pushes the first slider 241 to slide along the connecting member 21 toward the second slider 242.

The middle part of the first rotating member 2431 rotates relative to the connecting member 21, and the upper end of the second rotating member 2432 pushes the second slider 242 to slide along the connecting member 21 toward the first slider 241, so that the first slider 241 and the second slider 242 clamp the inductor skeleton.

[0036] like Figures 4 to 5 As shown, the linkage component 2434 includes a plurality of protrusions 24341 protruding from the connection block 2433, a first movable groove 24311 capable of sliding the protrusions 24341 is provided on the first rotating member 2431, and a second movable groove 24321 capable of sliding the protrusions 24341 is provided on the second rotating member 2432.

When the multiple protrusions 24341 follow the connecting block 2433 to move downward, the multiple protrusions 24341 push the first groove wall 24312 and the third groove wall 24322 respectively, so that the first slider 241 and the second slider 242 slide toward each other and get closer. When the multiple protrusions 24341 follow the connecting block 2433 to slide upward, the multiple protrusions 24341 push the second groove wall 24313 and the fourth groove wall 24323 respectively, so that the first slider 241 and the second slider 242 slide in the opposite direction and reset, and the first slider 241 and the second slider 242 move away from each other.

[0038] like Figures 4 to 5 As shown, the first slider 241 is provided with a protruding first protrusion 2411, the upper end of the first rotating member 2431 is provided with a first slide groove 24314 in which the first protrusion 2411 can move, the second slider 242 is provided with a protruding second protrusion 2421, and the upper end of the second rotating member 2432 is provided with a second slide groove 24324 in which the second protrusion 2421 can move.

The range of the angle between the connecting section 24315 and the inclined section 24316 is greater than 90°, so that the inclined section 24316 has a sufficient position for lateral movement when the first rotating member 2431 rotates. The structures of the first rotating member 2431 and the second rotating member 2432 are completely the same.

[0040] like Figure 5 As shown, the left clamping member 22 is provided with a first clamping groove 221, and the right clamping member 23 is provided with a second clamping groove 231.
