This invention discloses a transformer lead fixing device with deformation self-compensation function, relating to the field of transformer technology. The invention includes a fixing plate fixed to the transformer housing, a lead fixing component, a deformation self-compensation mechanism, and a pin mechanism. The deformation self-compensation mechanism includes a clamping component fixed to the end of the lead and multiple stops disposed on the fixing plate. The clamping component has a multi-segmented bent elastic structure, and the stops have inclined abutment surfaces. The pin mechanism adjustably mounts the lead fixing component to the fixing plate. When the lead fixing component is driven to move closer to the transformer housing, the clamping component and the inclined abutment surfaces of the stops abut against each other, generating elastic deformation and achieving electrical contact between the clamping component and the terminal block. This invention, through the multi-segmented bent elastic structure of the clamping component and the unidirectional displacement adjustment of the pin mechanism, achieves adaptive compensation for deformation caused by thermal expansion and contraction and vibration, ensuring long-term stable electrical contact between the terminal block and the lead, and facilitating subsequent maintenance and adjustment.

The utility model discloses a non-woven fabric processing and production corner cutting device which comprises a base, a supporting plate is arranged on one side of the upper wall of the base, a top plate is fixedly installed on the supporting plate, a through groove is formed in the top plate, a sliding frame is installed in the through groove in a sliding mode, a motor is fixedly arranged at the bottom of the sliding frame, and the motor is connected with the base. The non-woven fabric cutting device relates to the technical field of non-woven fabric processing, the pressing and covering assembly applies appropriate pressure to non-woven fabric through the combination of the pressing rod, the spring and the pressing plate, it is ensured that the fabric is smooth in the cutting process, sliding or wrinkling is avoided, the cutting precision and the edge flatness are improved, and the cutting efficiency is improved. And the adjusting assembly allows a user to change the corner cutting width according to the cutting requirement, and the applicability and flexibility of the equipment are improved.
