Specifically, as shown in fig. 3, the connector 11 is provided with a first groove 111, and the extending direction of the first groove 111 is the same as the axial direction (up-down direction shown in fig. 3) of the sleeve member 1, and the axial direction is not limited to a direction of a certain straight line, but may be a direction of a set of parallel lines, for example, the axial direction is a left-right direction shown in fig. 3 and is not limited to a straight line direction extending forward and backward. As shown in fig. 3, the length of the first groove 111 is smaller than the length of the joint head 11 in the axial direction; the first groove 111 may be a through hole groove penetrating through both sides of the connector 11, and it should be noted that, the inner side of the connector 11 is a side close to the hollow structure, and the outer side of the connector 11 is a side far away from the hollow structure. The first groove 111 may also be a groove structure that does not penetrate through the inner and outer sides of the connecting head 11, that is, the depth of the first groove 111 in the vertical axial direction is smaller than the thickness of the connecting head 11. The embodiment of the present invention is not limited to the specific penetrating form of the first groove 111 described above, as long as the first groove 111 can accommodate a part of the clamping member 2. According to the embodiment of the invention, the clamping component 2 is at least partially arranged in the first groove 111, so that on one hand, the first groove 111 can play a limiting role on the clamping component 2, and the stability of the clamping component 2 is improved; on the other hand, the first groove 111 can accommodate the clamping component 2, so that the clamping component 2 is accommodated in the first groove 111, and the structure of the material changing tool is simpler and more compact.
In some embodiments, as shown in fig. 3, the first grooves 111 are provided in plural, and the plural first grooves 111 are provided equidistantly in the circumferential direction of the joint head 11. Alternatively, the connector 11 may be provided in a polygonal shape in cross section perpendicular to the axial direction, and the number of sides of the cross section of the connector 11 may be the same as the number of the first grooves 111, that is, one first groove 111 is provided on each side of the polygonal shape.

One end of the opening of the outer sleeve 12 is fixedly connected with the connector 11 and is used for inserting the control rod moving body 3, so as to limit the control rod moving body 3; the lower end piece 13 and the outer sleeve 12 may be welded, connected by a connecting member, etc., and the embodiment of the present invention is not limited to the specific connection form of the lower end piece 13 and the outer sleeve 12, as long as the lower end piece 13 is fixedly connected with the outer sleeve 12. The outer sleeve 12 together with the lower end piece 13 provide structural support for the refueling tool such that the lower end piece 13 can be inserted directly into the core cascade header 4.

In some embodiments, as shown in fig. 1, the sleeve member 1 further comprises a compacting member 14. The pressing member 14 presses the control rod moving body 3 when the engagement member 2 is engaged with the control rod moving body 3. Specifically, during the process of inserting the control rod moving body 3 into the refueling tool, the control rod moving body 3 applies a force to the refueling tool in the axial direction toward the bottom of the sleeve member 1, so that the pressing member 14 is in a pressed state; under the condition that the clamping part 2 is connected with the limiting groove 31 on the control rod moving body 3, the pressed pressing part 14 applies opposite acting force to the control rod moving body 3, the acting force of the clamping part 2 clamped with the limiting groove 31 is increased by the opposite acting force, so that the connection between the clamping part 2 and the limiting groove 31 is more firm, and the connection reliability of a material changing tool and the control rod moving body is improved. According to the embodiment of the invention, the compaction part 14 is added in the sleeve part 1, so that when the control rod moving body is connected with the material changing tool, the control rod moving body can be compacted with the material changing tool, and the risk of unexpected unlocking of the material changing tool along with the control rod moving body due to vibration in the transferring process is reduced.
In some embodiments, as shown in fig. 1, the compacting member 14 includes a support sleeve 141, a support seat 142, and a second elastic member 143. The support sleeve 141 is provided in the outer sleeve 12, and the support sleeve 141 is provided in a structure having at least one end opened, specifically, one side of the support sleeve 141 near the connection head 11 is provided in an opened structure, so that the control rod moving body 3 can be partially inserted into the support sleeve 141. One end of the support sleeve 141 is detachably and fixedly connected with the lower end piece 13, specifically, one side of the support sleeve 141, which is close to the lower end piece 13, can be provided with a threaded structure, the lower end piece 13 is provided with a threaded groove matched with the threaded structure, and the support sleeve 141 is connected with the threaded groove of the lower end piece 13 through the threaded structure. Of course, the connection mode of the support sleeve 141 and the lower end piece 13 includes, but is not limited to, the above threaded connection mode, and the optional support sleeve 141 and the lower end piece 13 may also be connected by a clamping connection, a shaft pin fixing, etc., so long as the support sleeve 141 can be fixed in the circumferential direction and the axial direction relative to the lower end piece 13. As shown in fig. 1, the supporting seat 142 is disposed in the supporting sleeve 141, the supporting seat 142 is also configured as a hollow structure, a part of the control rod moving body 3 can be transmitted inside the supporting seat 142, the supporting seat 142 can move in the axial direction (up-down direction shown in fig. 1) relative to the supporting sleeve 141, during the process of inserting the control rod moving body 3 into the sleeve member 1, the control rod moving body 3 sequentially passes through the connector 11 and the outer sleeve 12, finally the control rod moving body 3 abuts against the supporting seat 142, the control rod moving body 3 drives the supporting seat 142 to move towards one side of the lower end member 13 relative to the supporting sleeve 141 until the clamping member 2 and the limiting groove 31 are aligned, and the clamping member 2 and the limiting groove 31 are fixed in both axial and radial positions.
