With the above structure, by extending in the length direction of the seat body 10 and the rotating member 40 being rotatably arranged on the seat body 10, the driving member 20 is drivingly connected to the rotating member 40, so that the driving member 20 can drive the rotating member 40 to rotate, and the first end of the first clamping plate 31 and the first end of the second clamping plate 32 are both drivingly connected to the rotating member 40, so that the first clamping plate 31 and the second clamping plate 32 can be driven to move closer to or away from each other under the action of the rotating member 40, so as to ensure that the lead seal can be disassembled.

[0033] like Figure 4As shown, the seat body 10 has a first guide groove 11, and the rotating member 40 includes a first bidirectional screw 41 arranged in the first guide groove 11. The rotation axis of the first bidirectional screw 41 extends along the length direction of the seat body 10. The first bidirectional screw 41 has a first left-handed thread segment and a first right-handed thread segment. The first end of the first clamping plate 31 is located in the first guide groove 11 and has a first threaded hole.

The first left-handed thread segment is threadedly matched with the first threaded hole, and the first right-handed thread segment is threadedly matched with the second threaded hole. With the above structure, a first guide groove 11 is provided on the seat body 10, so that the first bidirectional screw 41 can rotate in the first guide groove 11. Since the rotation axis of the first bidirectional screw 41 extends along the length direction of the seat body 10, the first clamping plate 31 and the second clamping plate 32 can move along the length direction of the seat body 10. Since the first bidirectional screw 41 has a first left-handed thread section and a first right-handed thread section, the first end of the first clamping plate 31 has a first threaded hole, and the first end of the second clamping plate 32 has a second threaded hole, and the first threaded hole and the second threaded hole are both located in the first guide groove 11, so that the first bidirectional screw 41 is threadedly matched with the first clamping plate 31 and the second clamping plate 32 respectively, so that the first clamping plate 31 and the second clamping plate 32 can be moved closer to or farther away from each other under the action of the first bidirectional screw 41.

[0034] Specifically, the first left-handed thread segment is threadedly matched with the first threaded hole of the first clamping plate 31, and the first right-handed thread segment is threadedly matched with the second threaded hole of the second clamping plate 32, so that the first left-handed thread segment and the first right-handed thread segment can move closer to or farther away from each other.

[0035] Furthermore, the first guide groove 11 can play a role of stopping and guiding the movement of the first clamping plate 31 and the second clamping plate 32 .

With the above structure, by setting the third clamping plate 33 and the fourth clamping plate 34, a second guide groove 12 is set on the seat body 10, the first guide groove 11 and the second guide groove 12 can be set at intervals in the width direction of the seat body 10, the first bidirectional screw 41 is rotatably set in the first guide groove 11, and the second bidirectional screw 42 is rotatably set in the second guide groove 12, the first end of the first clamping plate 31 and the first end of the second clamping plate 32 are both set on the first bidirectional screw 41, so that the first clamping plate 31 and the second clamping plate 32 can be driven to move closer to each other or away from each other under the action of the rotation of the first bidirectional screw 41. In addition, the first end of the third clamping plate 33 and the first end of the fourth clamping plate 34 are both set on the second bidirectional screw 42, so that the third clamping plate 33 and the fourth clamping plate 34 can be driven to move closer to each other or away from each other under the action of the rotation of the second bidirectional screw 42, so that the driving method is simple and convenient.

[0037] It should be noted that a third threaded hole is provided at the first end of the third clamping plate 33, and a fourth threaded hole is provided at the first end of the fourth clamping plate 34. Both the third threaded hole and the fourth threaded hole are located in the second guide groove 12, so that the third clamping plate 33 and the fourth clamping plate 34 can be controlled to approach or move away from each other under the action of the second bidirectional screw 42.

[0038] like Figure 4 As shown, a transmission structure 50 is provided between the first bidirectional screw 41 and the second bidirectional screw 42, so that the first bidirectional screw 41 and the second bidirectional screw 42 rotate simultaneously. With the above structure, by providing the transmission structure 50, the first bidirectional screw 41 and the second bidirectional screw 42 can rotate together through the transmission structure 50, thereby ensuring the reliability of the transmission structure 50.

The first gear 51 is sleeved on the end of the first bidirectional screw 41, and the second gear 52 is sleeved on the end of the second bidirectional screw 42. The first gear 51 and the second gear 52 are meshed. With the above structure, the first gear 51 is sleeved on the end of the first bidirectional screw 41, and the second gear 52 is sleeved on the end of the second bidirectional screw 42, and the first gear 51 and the second gear 52 can be meshed. When the first bidirectional screw 41 is driven to rotate, the second bidirectional screw 42 can be driven to rotate together under the action of the meshing of the first gear 51 and the second gear 52, so that the reliability of the transmission structure 50 can be ensured.

With the above structure, a mounting groove 311 is provided at the first end of the first clamping plate 31, and a fixing rod 314 is provided in the mounting groove 311. The pivot through hole 313 of the rotating plate 312 is sleeved on the fixing rod 314, so that the rotating plate 312 can rotate relative to the second end of the first clamping plate 31. When the second end of the first clamping plate 31 is needed to extend into the lead seal, the rotating plate 312 is in a storage position received in the mounting groove 311. This makes it easy to extend the first clamping plate 31 into the gap between the plug-in port and the lead seal. When extending into the plug-in port, the rotating plate 312 can be rotated so that the rotating plate 312 is in an outward swing position, which makes it easy to snap-connect the rotating plate 312 with the buckle of the lead seal, so that the rotating plate 312 can constitute a lead seal snap-on portion.
