[0028] An anti-skid sleeve 671 is fixedly sleeved on the output shaft of the pulling rod 67 to prevent skidding.

[0029] A mounting plate 691 is provided at the upper part of the front side of the connecting plate 69, and one side of the mounting plate 691 is fixedly mounted on the protective frame 61, a bolt 692 is installed through a thread on the mounting plate 691, and a plurality of slots 693 are provided at equal intervals on the front side of the connecting plate 69, and the output end of the bolt 692 is inserted into the inner cavity of one of the slots 693, thereby fixing the rectangular block 65.

[0030] In this embodiment: when in use, the plug assembly 4 can be inserted into the inner cavity of the socket 2. After the insertion is completed, the bolt 692 can be rotated to move it away from the inner cavity of one of the slots 693, and then the pull rod 67 is pulled upward. When the pull rod 67 moves upward, it will drive the rectangular block 65 to move upward.

When the sliding plate 62 moves to one side, it will drive the clamping plate 66 to move and insert it between the two trapezoidal blocks 5. At this time, the plug assembly 4 can be clamped and fixed. After fixing, the bolt 692 is rotated in the opposite direction to allow it to continue to be inserted into the inner cavity of one of the slots 693.

[0031] Embodiment 2: This embodiment is an improvement made on the basis of embodiment 1. For details, please refer to Figure 1-3 and Figure 5The sealing assembly 3 includes a rotating rod 31 arranged at the upper front side of the top of the converter housing 1 and a first threaded rod 32 fixedly installed at one end of the rotating rod 31, and a second threaded rod 33 is fixedly installed at the other end of the rotating rod 31, and side plates 34 are fixedly installed on both sides of the top front side of the converter housing 1, and one end of the first threaded rod 32 away from the rotating rod 31 is movably installed on the adjacent side plate 34, and threaded sleeves 35 are threadedly installed on the output shafts of the first threaded rod 32 and the second threaded rod 33, and L-shaped rods 36 are fixedly installed on the front sides of the threaded sleeves 35, and dustproof plates 37 are fixedly installed on the lower ends of the L-shaped rods 36, and the rear sides of the dustproof plates 37 are respectively fitted on the converter housing 1 to achieve sealing of the socket 2.

A knob 332 is fixedly installed at the other end of the transmission rod 331 to drive the second threaded rod 33 to rotate.

[0033] Guide plates 361 are respectively provided on the outer sides of the L-shaped rods 36, and the rear sides of the guide plates 361 are respectively fixedly mounted on the converter housing 1, and guide rods 362 are respectively slidably installed on the guide plates 361, and the inner ends of the guide rods 362 are respectively fixedly mounted on the L-shaped rods 36, so as to guide the movement of the L-shaped rods 36.

[0034] In this embodiment: when the socket 2 on the converter housing 1 is not in use, it can be sealed to prevent dust. The knob 332 is turned to drive the transmission rod 331 to rotate. When the transmission rod 331 rotates, it will drive the second threaded rod 33 to rotate. When the second threaded rod 33 rotates, it will drive the first threaded rod 32 to rotate through the rotating rod 31. When the first threaded rod 32 and the second threaded rod 33 rotate, the threaded sleeve 35 will be driven to move relative to each other. When the threaded sleeve 35 moves relative to each other, it will drive the dustproof plate 37 to move relative to each other through the L-shaped rod 36 to achieve sealing of the socket 2. When the dustproof plate 37 is fitted, the knob 332 can be stopped from being turned.

[0035] Working principle: When in use, the plug assembly 4 can be inserted into the inner cavity of the socket 2. After the insertion is completed, the bolt 692 can be rotated to make it away from the inner cavity of one of the slots 693, and then the pull rod 67 is pulled upward. When the pull rod 67 moves upward, it will drive the rectangular block 65 to move upward. When the rectangular block 65 moves upward, it will drive the sliding plate 62 to move to one side through the sliding shaft 64. When the sliding plate 62 moves to one side, it will drive the clamping plate 66 to move and insert it between the two trapezoidal blocks 5. At this time, the plug assembly 4 can be clamped and fixed. After fixing, the bolt 692 is rotated in the opposite direction to allow it to continue to be inserted into one of the slots 693. The inner cavity of the plug assembly 4 can be released by reverse operation, and the socket 2 on the converter housing 1 can be sealed and dustproof when not in use. Turning the knob 332 drives the transmission rod 331 to rotate. When the transmission rod 331 rotates, it drives the second threaded rod 33 to rotate. When the second threaded rod 33 rotates, it drives the first threaded rod 32 to rotate through the rotating rod 31. When the first threaded rod 32 and the second threaded rod 33 rotate, they drive the threaded sleeve 35 to move relative to each other. When the threaded sleeve 35 moves relative to each other, it drives the dustproof plate 37 to move relative to each other through the L-shaped rod 36 to achieve sealing of the socket 2. When the dustproof plate 37 is fitted, the knob 332 can be stopped from being turned.
