The application discloses a cutting device for cable protection pipe production and relates to the technical field of cutting devices.The cutting device comprises a frame one, a plate two is movably arranged on the inner side of the frame one, a configuration mechanism is arranged on the front of the plate two, the configuration mechanism comprises a connecting rope and a counterweight, one end of the connecting rope is connected with one end of the plate two, and the other end of the connecting rope is provided with the counterweight.The cutting device can make the cutter move backward together with the cable when the cable is cut, the cable can be cut without stopping, and the cutting efficiency is improved;after the cable protection pipe is cut by the cutter, the counterweight moves downward under the action of gravity, thereby driving the connecting rope to move downward;when the connecting rope moves downward, the plate two is driven to move forward, and then the plate two can return to the front without using a transmission device, cost is saved, and the plate two can move backward together with the cable protection pipe to realize the cutting of the cutter on the cable protection pipe.

This invention discloses an electroplating apparatus for ultra-thin PCBs with high and low copper bosses, relating to the field of printed circuit board processing technology. It includes: an electroplating gantry frame with a support rod mounted on it, and a clamping unit for holding and fixing the PCB substrate on the support rod. The clamping unit includes: a fixed frame fixed to the support rod, a connector detachably connected to the fixed frame, two sliding rods slidably connected within the connector, a fixed clamping block fixedly connected to the two sliding rods, a movable clamping block hinged to the fixed clamping block, and a fixed tension spring fixedly connected between the movable clamping block and the connector. This invention uses a substrate to push the fixed and movable clamping blocks together, changing the traction direction of the fixed tension spring on the movable clamping block, thereby keeping the fixed and movable clamping blocks in a clamped or open state. Thus, when fixing and removing the substrate, simply pushing the fixed clamping block with the substrate is sufficient to clamp and remove the substrate, improving operational convenience and reducing the probability of substrate misalignment and wear.

This invention provides a shielded cable installation mechanism, relating to the field of cable installation technology, including cables; it also includes a locking mechanism, which has two sets, including a fixed cylinder, the cable being slidably connected to the fixed cylinder, one end of the fixed cylinder having multiple sets of locking grooves, and the other end having a rotating groove, the rotating groove having multiple sets of balance springs, the fixed cylinder having multiple sets of sliding grooves, the outer wall of the fixed cylinder having a hexagonal groove, the rotating groove having a locking ring rotatably connected to it, the locking ring having multiple sets of unlocking grooves, the multiple sets of balance springs corresponding one-to-one with the multiple sets of unlocking grooves, the two ends of the balance springs being fixedly connected to the inner side wall of the unlocking groove, and the outer wall of the locking ring having multiple sets of friction strips. This invention overcomes the problem of traditional cable installation requiring separate fixing of the cable body, shielding tube, and corrugated tube, and designs an integrated synchronous locking mechanism, realizing one-time rapid synchronous locking of the cable, shielding tube, and corrugated tube.
