By providing the fixing device, the first fixing portion 14 is relatively fixedly connected to the tower 20, and then the lead 30 is relatively fixedly connected to the second fixing portion 16, so that the tower 20 and the lead 30 are relatively fixed. Therefore, the suspended lead 30 is effectively prevented from swinging under the influence of wind, abrasion between the lead 30 and the tower 20 due to swinging and contact is avoided, the service life of the lead 30 is prolonged, and the cost is reduced. Meanwhile, the lead 30 keeps working normally for a long time, and the counting accuracy of the counting meter is also ensured.
In some embodiments, the first fixing portion 14 and the second fixing portion 16 are both elastic, the first fixing portion 14 and the connecting portion 12 form a first clamping position for clamping the tower 20, and the second fixing portion 16 and the connecting portion 12 form a second clamping position for clamping the lead 30.
Further, the first fixing portion 14 and the second fixing portion 16 are both curved to form a first clamping position and a second clamping position with the connecting portion 12, respectively.
In practical application, a preset distance is reserved between the first clamping position and the second clamping position, so that the tower 20 is fixed at the first clamping position, the lead 30 is fixed at the second clamping position, and a distance is reserved between the tower 20 and the lead 30, so that the tower 20 and the lead 30 are further prevented from contacting, and abrasion is avoided.
In some embodiments, the fixing device further includes a first extending portion 11, one end of the first extending portion 11 is fixedly connected to one end of the first fixing portion 14 far away from the connecting portion 12, and the other end of the first extending portion 11 extends toward the other end of the connecting portion 12 and inclines toward a direction close to the connecting portion 12.

In some embodiments, the first fixing portion 14, the connecting portion 12 and the second fixing portion 16 are integrally formed. Further, the entire fixing device, i.e., the first extending portion 11, the first fixing portion 14, the connecting portion 12, the second fixing portion 16 and the second extending portion 13, is integrally formed. Specifically, both ends of a strip-shaped metal sheet are bent to form the fixing device.
Thus, a clamping position exists between the first fixing portion 14 and the connecting portion 12, and the metal sheet still has a certain elasticity after being formed, so that the corresponding clamping position can be changed. When the fixing device is used, the clamping position formed by the first fixing part 14 and the connecting part 12 is firstly opened, then the tower 20 is clamped, the clamping position formed by the second fixing part 16 and the connecting part 12 is opened, the lead 30 is clamped, and the tower 20 and the lead 30 are respectively fixed with the fixing device, so that the relative fixing between the tower 20 and the lead 30 is realized.
