On the basis of the above embodiment, it is preferable that the center line of the mounting hole 4 is a vertical line or a horizontal line.
It should be noted that the center line of the mounting hole 4 is a vertical line, so that the center line of the mounting hole 4 and the center axis of the body 12 are perpendicular to each other in a vertical plane, so as to ensure that the bolt length is not limited when the external joint is mounted in the mounting hole 4. The center line of the mounting hole 4 is a horizontal line, so that the center line of the mounting hole 4 and the center axis of the body 12 are perpendicular to each other in a horizontal plane, so as to ensure that the length of the bolt is not limited when the external joint is mounted in the mounting hole 4.
In addition, the center line of the mounting hole 4 may intersect the center axis of the body 12 in a vertical plane or a horizontal plane, for example, an angle between the center line of the mounting hole 4 and the center axis of the body 12 in the vertical plane or the horizontal plane is 45 ° or 60 °, but there is a problem that it is inconvenient to process. I.e. the shape, position, etc. of the mounting holes 4 can be determined according to the actual situation and the actual requirements.
Preferably, the mounting hole 4 is a threaded hole, so that the bolt assembling operation can be performed quickly, and the mounting hole 4 can be processed and manufactured conveniently.

Therefore, when the protective cover 5 needs to be mounted on the outer side of the second end structure 2, the sliding rail 53 and the sliding groove portion 32 can be assembled, and the sliding rail 53 is pushed to move along the sliding groove portion 32 until the clamping position 54 is clamped with the mounting table 31, at this time, the protective cover 5 and the connecting seat 3 are assembled in place. When the protective cover 5 needs to be removed, the protective cover 5 can be reversely slid and the protective cover 5 can be removed.
It should be further noted that, when in use, the protection cover 5 can slide into the DC terminal along four directions, and the protection cover 5 is provided with a sliding rail 53 and a clamping position 54, so that the protection cover 5 can be effectively clamped, and the protection cover 5 is ensured not to fall off in the product transferring process. When in use, the protective cover 5 can slide in different directions according to different requirements of products, namely, the protective cover 5 can slide into the DC terminal transversely along the transverse sliding groove 321, or the protective cover 5 can slide into the DC terminal vertically along the vertical sliding groove 322.
The second end structure 2 can be effectively protected from damage during transfer of the DC terminals by using a protective cover 5. And, the visor 5 is detachably connected with the connection base 3, and when one of the visor 5 or the DC terminal is damaged, the damaged part can be replaced through the disassembling operation, and then the new part and other undamaged parts are continuously matched for use, so that the service life of the device is prolonged, and the maintenance cost of the device is reduced.
