[0049] Optionally, the head detection component 11 further includes a head adjustment assembly 112, and the head detection contact pin 111 is arranged on the head adjustment assembly 112; the head adjustment assembly 112 has an adjustment degree of freedom in the axial and / or radial direction of the head detection contact pin 111, and is used to move the head detection contact pin 111 in the axial and / or radial direction of the head detection contact pin 111, so that the head detection contact pin 111 can abut and contact the stimulating member 910 of the head portion 91. In some embodiments, the position of the head detection contact pin 111 in the axial direction relative to the head adjustment assembly 112 is adjustable, for example, the head detection contact pin 111 can be fixed or loosened by a jackscrew arranged on the head adjustment assembly 112, so as to adjust the head detection contact pin 111. In other embodiments, the head detection contact pin 111 can move axially and / or radially together with a part of the head adjustment assembly 112 after being installed on the head adjustment assembly 112, so as to align the stimulating member 910 to be detected. Preferably, the head detection contact pin 111 is detachably connected with the head adjustment assembly 112, so as to facilitate replacement of the head detection contact pin 111.

[0050] Please refer to Figure 5 andFigure 6 In an alternative example, the axial direction of the head detection stylus 111 is perpendicular to the first axis A1, and the adjustment freedom of the head adjustment assembly 112 along the radial direction of the head detection stylus 111 includes a vertical adjustment freedom and a horizontal adjustment freedom; the vertical direction is parallel to the first axis A1, and the horizontal direction is perpendicular to both the first axis A1 and the axial direction of the head detection stylus 111. It can be understood that, in the above example, the vertical direction is parallel to the horizontal direction, and the horizontal direction is perpendicular to the vertical direction. Figure 5 And Figure 6 In the example shown, the vertical direction refers to the up-down direction, and the horizontal direction refers to the direction parallel to the base 3. In this configuration, the head adjustment assembly 112 can fine-tune the position of the head detection stylus 111 to adapt to different electrode leads.

[0053] Generally, in order to facilitate the electrical conduction during the connection, the connecting contact 920 of the tail end part 92 is arranged in a ring shape, so that the tail end detection component 21 does not need to be arranged circumferentially around the second axis A2, and multiple tail end detection components 21 are also not needed. Based on this, the tail end adjusting assembly 212 is configured to be rotatable around the third axis A3, so that the tail end detection probe 211 arranged thereon can be conveniently brought into abutting contact with the connecting contact 920.

[0054] Optionally, the position of the tail end detection probe 211 along the axial direction thereof relative to the tail end adjusting assembly 212 is adjustable.
