The present invention relates to the improvement of a bracket case for orthodontics. Particularly, the present invention facilitates the discrimination of a bracket for orthodontics stored in a case and allows an medical operator to discriminate and easily select a bracket when the medical operator selects the bracket suitable for the teeth and bonds and fixes the selected bracket to the outside of the teeth for the straightening of irregular teeth. The present invention provides a recessed groove in double rows on a main body which forms the bracket case for orthodontics, forms the shape of the recessed groove in sequence of a set of teeth, forms simultaneously the shape of the recessed groove into the shape of the teeth, and stores the bracket suitable for the same teeth as the shape of the recessed groove within each recessed groove so as to easily select the bracket suitable for the teeth viewing the shape of the recessed groove. A through hole is made in the bottom of the recessed groove as necessary. The bonding surface of an adhesive tape is exposed within the recessed groove through the through hole by bonding the adhesive tape in the bottom side. And, the bracket is bonded and fixed to the bonding surface in the arranged state. Thus, the bracket stored in the recessed groove is not fluctuated and stored in the arranged state.

The invention discloses a cutter for milling high-quality plate edges and a processing method thereof. A set of spiral cutting slots and a set of spiral tooth breaking slots are arranged on a cutter head of the cutter for milling high-quality plate edges, wherein the spiral cutting slots are used for forming cutting edges, and the spiral tooth breaking slots are crossed with the cutting slots andused for breaking the cutting slots to form edge teeth; and a set of spiral tooth disordering slots respectively crossed with the cutting slots and the tooth breaking slots are also arranged on the cutter head. The cutter for milling high-quality plate edges in the invention is additionally provided with one set of tooth disordering slots, the spiral angles of the tooth disordering slots are different from the spiral angles of the cutting slots and the tooth breaking slots, the tooth disordering slots pass through the edge teeth formed by the cutting slots and the tooth breaking slots to formnew irregular tooth slots on the passed edge teeth ,and the regular and uniform distribution of the original cutting edge teeth is destroyed so that many cutting edges are not symmetrical any more. As the regularity of the edge teeth on the cutting edges of the milling cutter is destroyed by the tooth disordering slots, no periodical regularity exists when a plate is milled and cut so that the milled plate edges are flat without corrugations.

The invention relates to a motor with irregular tooth tops capable of reducing the radial electromagnetic excitation force. The structure of the motor is the same as that of the prior art, and it is characterized by: A number of teeth with irregular tooth tops are set on the stator core and the rotor core at the same time. The tooth tops of the teeth are composed of several small teeth. The structure, as long as the perimeter of the addendum can be increased so that the radial force is a component of the normal force, it will all play a role in reducing the radial electromagnetic excitation force. When the tooth tip of the tooth adopts a sawtooth structure, it can adopt a one-way sawtooth structure or a two-way sawtooth structure, and the included angle between the hypotenuse and radial sides of the sawtooth structure can be selected according to requirements. The invention can be widely used in various motors such as permanent magnet motors, asynchronous motors, electric excitation synchronous motors and switched reluctance motors.

A unidirectional ratchet wrench structure has a wrench member, a pawl and a ratchet. The wrench member has an accepting space for accommodating the ratchet and an accepting space for accommodating the pawl. A toothed section of the pawl has a plurality of equiangular teeth and an irregular tooth. Since the irregular tooth is lower than the height of the equiangular teeth, the irregular teeth irregular tooth is capable of quickly disengaging from the equiangular teeth of the ratchet. The arc section and the toothed section have different arc measures and not push against the outer periphery of the ratchet at the same time, through the abutment of the pivoting point and the change of the center of gravity of the pawl when the wrench is rotated, the pawl is capable of producing a seesaw yaw movement to achieves the effect of quick engagement and disengagement.

Disclosed is a toothed metal framework composite gasket having irregular teeth, comprising a metal framework having tooth-shaped protrusions and a non-metallic sealing material (6), wherein multiple circles of irregular teeth curved in the direction of a pressure source are distributed radially and concentrically along upper and lower end faces of the metal framework, which are covered by a filled non-metallic sealing material. Compared with conventional sealing teeth, new moon-shaped or bow-shaped teeth provide two additional resilient points and additional flexibility, preventing stress building up at two break points at a top part and a root part of the teeth, having relatively high anti-yielding and anti-fatigue performance, and increasing the service life of the gasket. Moreover, a pressure-prevention boss (4) is designed between the irregular teeth, preventing crushing and damage of the irregular teeth caused by excessive pre-stressing force, and ensuring security of sealing. The toothed metal framework composite gasket achieves extremely large improvements in elasticity, toughness, and compression resistance, has a relatively high elastic resilience and pressure bearing capacity, and will not be crushed and does not damage a flange.
