[0025] In order to make the technical means, creative features, objectives and effects achieved by the present invention easier to understand, the present invention is further described below in conjunction with specific implementation methods:

[0027] By inserting the plug-in column 21 into the interior of the sliding slot and making the circular fixing frame 33 stuck in the interior of the fixed slot 22, the plug-in column 21 can be fixed, thereby fixing the connecting cover 2. When the connecting cover 2 is removed, the transmission screw 32 can be rotated by rotating the knob 31, and the circular fixing frame 33 can be slid, thereby being disengaged from the fixed slot 22, so that the plug-in column 21 is no longer restricted, making it convenient to remove the connecting cover 2, making it more convenient to maintain the transformer rectifier 1, and facilitating the use of the transformer rectifier 1.

[0033] When the wire passes through the connecting hole 44, the driving slider 45 is released to allow the sliding baffle 43 to slide upward, so that the annular slider 441 can press the wire tightly. At the same time, the sliding of the annular slider 441 in the connecting hole 44 can squeeze the spring three 442, and the rotating pressure plate 443 can be squeezed by the limiting groove to rotate, so that the rotating pressure plate 443 can rotate and press the wire tightly, so that the connection effect between the transformer rectifier 1 and the wire is better, and the loosening of the wire is avoided.

[0034] The following is a detailed description of the working principle of the transformer rectifier which is easy to maintain.

[0035] like Figures 1-5As shown, the voltage transformer rectifier 1 is blocked in the wire insertion hole 42 by the sliding baffle 43, which can avoid external dust from entering the inside of the wire insertion hole 42, causing poor contact of the wire insertion hole 42, and when in use, the sliding baffle 43 can be driven to slide by the driving sliding block 45, so that the communication hole 44 is in communication with the wire insertion hole 42, facilitating the voltage transformer rectifier 1 to connect the wire joint, and at the same time, the insertion column 21 is inserted into the sliding slot, and the back-shaped fixing frame 33 is clamped in the fixed clamping groove 22, which can fix the insertion column 21 and the connecting cover plate 2, when the voltage transformer rectifier 1 is disassembled and maintained, the knob 31 can drive the transmission screw 32 to rotate, and the back-shaped fixing frame 33 can be separated from the fixed clamping groove 22, so that the insertion column 21 is lost, the connecting cover plate 2 is conveniently disassembled, and the maintenance of the voltage transformer rectifier 1 is more convenient.

[0036] The above has made a detailed description of the utility model in general, but some modifications or improvements can be made on the basis of the utility model, which is obvious to those skilled in the art. Therefore, the modifications or improvements without departing from the spirit of the utility model are within the protection scope of the utility model.
