The utility model discloses a safety lock for an electrical cabinet, and belongs to the technical field of safety locks, the safety lock comprises a lock body, a bolt and a key, the lock body comprises a body, a lock cylinder and a support marble, the lock cylinder is rotatably matched with the body, the support marble is matched with the body in a sliding mode in the length direction of the lock cylinder, the lock cylinder is provided with at least two support grooves, and the bolt is inserted into the support grooves. The body is provided with a support spring, and the support marble is inserted into one of the support grooves under the elastic action of the support spring. The key is matched with the lock cylinder in an inserted mode, and when the key is inserted into the lock cylinder, the support marbles are separated from the support grooves. The bolt is matched with the body in an inserted mode, the body is matched with a locking marble in a sliding mode, and when the support marble is separated from the support groove and the lock cylinder is rotated, the locking marble locks or unlocks the bolt. The cabinet door has the advantages that the cabinet door is not prone to being opened or closed by mistake after the key is inserted into the lock cylinder, and safety is improved.

The utility model discloses a pearl puncher's feeding mechanism, including the adsorption disc main part and the connecting rod of setting at the adsorption disc main part upside position, the fixed link of setting at the adsorption disc main part downside position, the downside terminal position of fixed link is provided with rubber adsorption disc, the middle inboard position of rubber adsorption disc, fixed link, adsorption disc main part and connecting rod is set up to have the suction chamber, and the elastic force is continuously exerted in the adsorption process to the outer spring, guarantees the always tight adhesion of the outer sleeve rubber pearl surface. This makes the connection between pearl and rubber adsorption disc more stable, effectively prevents the pearl from falling off due to reasons such as shaking, jolt in the handling process. Whether in the smooth movement process or in the slight vibration environment that the equipment operation can produce, can ensure that the pearl is firmly grabbed, greatly improves the reliability of feeding, reduces the production interruption or product damage risk caused by the pearl falling.
