Therefore, the operating rod of the box-type transformer of the present application is easy to align with the male head of the operating hole, and the operation is convenient.

Therefore, the operating rod of the box-type transformer of the present application is convenient for aligning the male connector of the operating hole, and is easy to operate.
[0048] In some other embodiments, the box-type transformer operating rod provided in the present application, the handle assembly 100 includes a vertical rod 110 and an adjustment hole 120 , the vertical rod 110 is slidably connected to the connecting member 210 , and the adjustment hole 120 is arranged on the vertical rod 110 .
[0049] In a specific implementation, the vertical rod 110 is arranged along the vertical direction, and the extension direction of the vertical rod 110 is perpendicular to the extension direction of the connecting member 210. The vertical rod 110 is slidably connected to the connecting member 210, and the connecting member 210 is fixed on the vertical rod 110 through the adjustment hole 120. The vertical rod 110 is rotated to drive the connecting member 210 to rotate around its own axis, so that the connecting female head 220 and the male head of the operating hole of the transformer rotate synchronously, thereby turning the transformer on or off.
[0050] The box-type transformer operating lever in the embodiment of the present application controls the rotation of the connecting member 210 by rotating the vertical rod 110, thereby realizing the operation of the transformer. The fixed position of the connecting member 210 can be flexibly adjusted through the adjustment hole 120, so that the female connector 220 and the male connector of the transformer operating hole can rotate synchronously.
[0051] In some embodiments, the box-type transformer operating rod provided in the present application has a plurality of adjustment holes 120 , which are arranged at intervals along the extension direction of the vertical rod 110 .

The connecting rod 211 is slidably connected to the vertical rod 110, and the adjusting portion 212 is arranged at one end of the connecting rod 211 and away from the connecting female head 220, so that the adjusting portion 212 can flexibly adjust the connection state between the connecting rod 211 and the vertical rod 110, so that the connecting rod 211 slides along the extension direction of the vertical rod 110, and when the connecting rod 211 moves to a suitable position, the adjusting portion 212 is plugged into the connecting rod 211, so that the connecting rod 211 is fixed on the vertical rod 110.
[0055] In some embodiments, the adjustment portion 212 may be a latch, and the connection state between the connecting rod 211 and the vertical rod 110 is adjusted by connecting or disconnecting the latch. When the latch is inserted into the adjustment hole 120, the connecting rod 211 is connected to the vertical rod 110 and thus fixed at a specific position; and when the latch is disconnected from the adjustment hole 120, the connecting rod 211 can slide along the extension direction of the vertical rod 110 to achieve position adjustment and change.
[0056] In some embodiments, the box-type transformer operating rod provided in the present application, the handle assembly 100 further includes a grip 130 , and the grip 130 is disposed at one end of the vertical rod 110 .
[0057] In a specific implementation, the handle assembly 100 further includes a grip 130, which is disposed at one end of the vertical rod 110. The operator grips the grip 130 to facilitate the rotation of the vertical rod 110.
[0058] In some embodiments, there are two grips 130, which are disposed at both ends of the vertical rod. In the embodiment of the present application, the vertical rod 110 is subjected to uniform force by two grips 130, thereby enhancing the durability of the vertical rod 110. The double grip design can also provide more gripping options, adapt to the needs and habits of different operators, and increase the flexibility and applicability of the operation.
[0059] In some embodiments, the box-type transformer operating rod provided in the present application has an insulating layer provided on the handle 130 .
[0060] In a specific implementation, an insulating layer is provided on the grip 130 to provide additional safety and electrical insulation performance. The insulating layer can be made of insulating materials, such as rubber, plastic, etc., and the present application does not limit this, as long as it has good insulation performance and wear resistance.
[0061] In some embodiments, the box-type transformer operating rod provided in the present application has a connecting cavity 221 in the connecting female head 220, and a chamfer is provided on the connecting cavity 221, and the connecting cavity 221 is used to be plugged with the operating hole male head of the transformer.
[0062] The female connector 220 has a connecting cavity 221, and the upper part of the connecting cavity 221 is provided with a chamfer. The chamfer increases the probability of the male connector of the operating hole being connected to the connecting cavity 221, facilitates the clamping of the male connector of the operating hole and the connecting cavity 221, and improves the plugging efficiency of the female connector 220 and the male connector of the operating hole.
[0063] The chamfered design helps to guide and position the male plug of the transformer's operating hole to be inserted into the connection cavity 221 .
[0064] In some embodiments, the operating rod of the box-type transformer provided in the present application has a plurality of damping strips disposed on the inner wall of the connecting cavity 221 , and the damping strips are disposed along the extension direction of the connecting cavity 221 , and the damping strips are used to increase the friction force so that the connecting cavity 221 is tightly plugged into the male head of the operating hole of the transformer.
[0065] A plurality of damping strips are arranged on the inner wall of the connecting cavity 221 . The damping strips are arranged along the extending direction of the connecting cavity 221 . The damping strips are used to increase the friction force.
[0066] The design of arranging a plurality of damping strips on the inner wall of the connection cavity 221 is intended to increase the friction force inside the connection cavity to prevent accidental separation between the connection female head 220 and the operation hole male head when the operating rod is rotated. These damping strips are arranged along the extension direction of the connection cavity 221 to form a damping mechanism to help maintain a tight connection between the connection female head 220 and the operation hole male head to prevent accidental separation caused by external force or vibration.
[0067] In some embodiments, the operating rod of the box-type transformer provided in the present application has a plurality of chamfers, which are arranged at intervals along the circumference of the connecting female head 220 so that the cross-section of the connecting cavity 221 is a polygon.
[0068] A plurality of chamfers are arranged at intervals along the circumference of the female connector 220, which can increase the number of sides and angles of the polygonal cross-section of the connection cavity 221. The design of these chamfers can make the shape of the connection cavity more complex, improve the matching degree and connection stability with the male connector of the operation hole. The polygon involves multiple angles, and two angles can clamp the male connector of the operation hole. Since the polygon contains multiple angles, the probability of connection between the male connector of the operation hole and the angle is increased, which facilitates the clamping of the male connector of the operation hole with the angle, so that the connection cavity in the female connector 220 can be quickly plugged into the male connector of the operation hole, improving the plugging efficiency of the female connector 220 and the male connector of the operation hole.
[0069] Due to the arrangement of multiple chamfers, the cross section of the connecting cavity 221 is polygonal, such as Figure 3 As shown, it can be a pentagon, a hexagon or a more polygonal shape. This design can increase the number of sides and angles of the connection cavity, making it easier for the male plug of the operating hole to find a matching position during insertion, thereby improving the accuracy and stability of insertion. Due to the presence of multiple angles, the male plug of the operating hole can more easily match the angle of the connection cavity during insertion, reducing friction and resistance during insertion, and improving insertion efficiency and smoothness.
[0070] By designing multiple chamfers, polygonal connection cavities and increasing the number of angles, the plug-in design of the connection female head 220 and the operation hole male head can be optimized, the plug-in efficiency and connection stability can be improved, thereby meeting the connection requirements.
[0071] In some possible implementations, the operating lever of the box-type transformer provided in the present application has an indicator light disposed on the outer side wall of the connecting female connector 220 .
[0072] In a specific implementation, an indicator light is provided on the outer wall of the female connector 220 to help the operator observe the plugging status of the female connector 220 and the male connector of the transformer operation hole, especially in a dim space with insufficient lighting. The indicator light can be an LED light or a light-emitting diode light strip, and this application does not limit this. Exemplarily, the indicator light is arranged around the female connector 220, and an indicator light is provided corresponding to each chamfer. This layout can make the indicator lights evenly distributed, which is convenient for the operator to observe from different angles and perform plugging.
[0073] In addition, the indicator light can also be electrically connected to the male head of the transformer's operating hole. The operator can visually judge the connection status between the female connector 220 and the male head of the transformer's operating hole by observing the on and off, flashing or color change of the indicator light, thereby improving the efficiency and accuracy of the connection work.
