The utility model belongs to the field of shaving equipment, and discloses a shaver which comprises a tool apron, a blade and a handle. The blade is arranged on the tool apron; at least one side of the blade is provided with a cutting edge; the tool apron is provided with two oppositely-arranged first sides and two oppositely-arranged second sides adjacent to the first sides. The cutting edge of the blade is arranged on the first side of the tool apron; the position, located between the two first sides, of the tool apron is a middle section, the length of the first sides of the tool apron is smaller than that of the middle section, notches are formed in the positions, corresponding to the first sides, of the second sides of the tool apron, and the length of the cutting edges is matched with that of the first sides. According to the shaver, when the edge corner of the cutting edge is used for shaving beards below nostrils, the problem that the edge corner position, corresponding to the first side, of the second side of the shaver holder abuts against the skin and is not attached to the skin can be effectively solved, and therefore the effect and efficiency of shaving the beards below the nostrils are improved.

The utility model provides a current transformer which comprises a base and a cover plate, the base comprises a bottom plate, a mounting support plate vertically arranged on the bottom plate and two opposite side plates, one side of each side plate is provided with the mounting support plate, the other side of each side plate forms a first opening, one side of the cover plate is provided with a baffle plate which extends towards the bottom plate and is inserted into the first opening, and the baffle plate is provided with a second opening. The baffle, the two side plates and the installation supporting plate define a containing cavity used for containing a coil, a U-shaped blocking edge arranged around the edge of the baffle is formed on the face, away from the containing cavity, of the baffle, a U-shaped groove is defined between the U-shaped blocking edge and the baffle, a second opening of the U-shaped groove faces the bottom plate, and only the edge of a label needs to be inserted into the U-shaped groove in the installation process. And then the cover plate and the base are assembled, and the bottom plate of the base blocks the opening of the U-shaped groove, so that the sign is prevented from falling out, and compared with the prior art, the operation is very simple and rapid, later replacement is facilitated, and meanwhile, parameters can be conveniently identified when light is dark.

An automatic screw feeding mechanism solves the problems that an existing manual screw feeding operation mode is large in labor intensity, low in production efficiency, prone to neglected feeding and wrong feeding, difficult to meet quality requirements and incapable of adapting to automatic production. Comprising a bottom plate, a sliding seat supporting base is arranged on the front portion of the bottom plate, a screw feeding longitudinal sliding seat above the sliding seat supporting base is connected with a fixed guide block in a sliding mode through two sets of sliding seat longitudinal moving guide rails, and a fixed table lifting mechanism is arranged between a screw fixing table above the screw feeding longitudinal sliding seat and the screw feeding longitudinal sliding seat. The guide rail moving connecting frame is connected with a guide rail driving motor; a screw feeding mechanism above the screw fixing table is arranged on the fixed connecting cross beam in a sliding mode, and a screw feeding transverse moving frame is connected with a moving frame driving motor. The device is reasonable in design, compact in structure, low in labor intensity, high in production efficiency, good in safety and convenient to operate, can avoid the situation that the production takt is affected due to the fact that the number of installed bolts is large, and effectively prevents neglected installation and wrong installation of the bolts.
