The second accommodating groove 12 and the first accommodating groove 11 are respectively bolted to the first cover plate 61 and the second cover plate 62. The first cover plate 61 is provided with a shifting hole 611, and a shifting rod 63 is slidably installed in the shifting hole 611. The end of the shifting rod 63 is connected to the first clamping member 41, and a positioning block 7 is fixedly installed in the middle of the placement groove 14.

[0040] Specifically, a C-link 2 and a first clamp 41 are provided which can slide, and a second clamp 42 is fixedly installed on the C-link 2. Through the action of the reset spring 5, the first clamp 41 and the second clamp 42 are fixed on the four sides of the placement slot 14 to the C-shaped magnetic core and the connecting piece installed in the placement slot 14. A connecting protrusion 3 is provided between the two C-links 2, and the connecting protrusion 3 is fixedly connected to the first clamp 41 in the sliding direction. When the lever 63 slides, the first clamp 41 slides with it, thereby causing the connecting protrusion 3 to slide. When the two first clamps 41 move away from each other, the convex portion of the connecting protrusion 3 slides between the two C-links 2, causing the C-link 2 to drive the second clamp 42 to move away from each other, thereby taking and placing the C-shaped magnetic core.

[0041] In this way, the first clamping member 41 and the second clamping member 42 provided under the action of the return spring 5 complete the positioning of each welding part of the C-shaped magnetic core, so that each part of the C-shaped magnetic core is in a relatively fixed state, which is convenient for welding.

[0042] In some feasible embodiments, the connecting protrusion 3 is a trapezoidal block, and the side of the C-link 2 close to the connecting protrusion 3 is set to be inclined.

[0043] The first clamping member 41 is connected to the connecting protrusion 3 by a pin or bolt penetrating the mounting through hole 13, so that when the first clamping member 41 slides when the lever 63 is moved, the connecting protrusion 3 is driven to slide synchronously. The placement groove 14 is a groove position set according to the C-shaped magnetic core. Two C-shaped magnetic cores are placed in the placement groove 14 in a mirror-symmetrical manner. The first clamping member 41 is against the side of the C-shaped magnetic core, and the second clamping member 42 is against the side of the connecting piece.

The lever 63 is a cylindrical rod. When the lever 63 is moved, the first clamping member 41 is opened, and at the same time, the first clamping member 41 drives the connecting protrusion 3 to slide. The connecting protrusion 3 pushes the C-type connecting rod 2 to open the second clamping member 42, and then the C-type magnetic core part is taken out or put in. After the lever 63 is released, the first clamping member 41 and the second clamping member 42 are reset under the action of the reset spring 5.

[0045] The positioning block 7 is in the shape of a rectangular plate and is located between the two C-shaped magnetic cores. The thickness of the positioning block 7 is set according to the required gap between the two C-shaped magnetic cores.
