The utility model belongs to electric welding machine equipment technical field discloses a kind of electric welding machine current remote control device, the rotation angle of current control knob is realized to the control of electric welding machine current size by control, the electric welding machine current remote control device includes remote control module, wireless communication module, controller, box, pivot, driving part, transmission rod subassembly, camera probe and display, using remote control module remote control mode, control driving part drives pivot rotation, pivot is connected with the current control knob of electric welding machine by driving subassembly, transmission rod subassembly passes on the torque of pivot to current control knob, compared with the connection mode of hose, transmission rod subassembly cannot distort storage elastic potential energy, effectively prevent the misrotation of current control knob, can ensure that the rotation ratio of pivot and current control knob is 1:1 accurate transmission, and feedback to the adjustment result by camera probe, realize the accurate adjustment of operator to current control knob rotation angle.

This utility model relates to the field of trailer technology, providing a trailer with a bidirectional retractable and foldable awning. It includes a trailer board, with base blocks fixed to both sides of the bottom end of the trailer board. A mop is hinged to the outer wall of one end of the base block. Both sides of the trailer board have longitudinal retraction structures, and the top of each longitudinal retraction structure has a transverse retraction structure fixed to it. This utility model, by incorporating the transverse retraction structure, allows the slide block and moving rod to move via a lead screw under the drive of a servo motor, realizing the unfolding and folding of the transverse awning along the length of the trailer board. This achieves the functions of "bidirectional retraction" and "foldability," allowing the width of the transverse awning to accommodate goods of different sizes. Automatic retraction is achieved via the servo motor, making operation simple. This device provides a convenient function for lateral retraction of the transverse awning, improving the adaptability and convenience of the foldable awning trailer during use.
