The invention belongs to the field of ornament as well as self-defense articles, relating to a combined decoration self-defense ring provided with a ring circle. The ring circle is connected with a protrusion, and the protrusion is connected with a detachable decoration self-defense part; specifically, the decoration self-defense part can be connected with the ring circle by screw threads; in order to firmly connect the protrusion with the decoration self-defense part, the connection surface of the protrusion and the decoration self-defense part is a plane; in order to prevent rings from rotating, the upper part of the ring circle adopts circular arc structure, and the connection of the ring circle and the protrusion is in detachable or non-detachable connection. The invention has beautiful appearance and changeable modelling and adopts the novel design of combined structure to ensure that the self-defense function has total imperceptibility, has strong aggressivity and can not cause accidental injury.

The invention discloses an assembling tool for a shell and a stator of a direct drive motor. The assembling tool comprises a base, guide rods, a support ring and a guide ring. The upper end of the base is connected with the guide rods. A base boss is arranged in the center of the upper end face of the base. The support ring is installed on the upper end face of the base. A stator is attached to the outer wall of the base boss. The lower end face of the stator abuts against the support ring in an attached mode. The guide ring comprises a mounting table, and a mounting table lower bulge is formed on the lower end face of the mounting table. Lower bulge through holes penetrating through the inner and outer walls are formed in the mounting table lower bulge. The inner end of each lower bulge through hole abuts against a ball. The inner ends of the balls are exposed out of the lower bulge through holes and abut against the outer wall of the stator. A heat insulation ring is arranged on theupper end face of the mounting table, and the heat insulation ring abuts against the shell in an attached mode. The shell includes a second shell body matched with the stator. The shell is pressed downwards to drive the guide ring to be pressed downwards along with the guide rod so that the second shell body can be pressed into the outer wall of the stator in an interference fit manner. In the invention, the stator is fixed reliably and firmly, the temperature of the shell will not decrease rapidly, and the assembly of the shell and the stator is premise, reliable and efficient.

A multifunctional tractor for cervical vertebra and lumbar vertebra is composed of chair, vertical column, horizontal arm for tracting cervical vertebra, a main control box for controlling chair and bed, and the reposition physiotherapeutic equipment.

The invention relates to an efficient blister film slitting device and a slitting method thereof. The slitting device comprise a fixing plate, a tube core supporting mechanism and a slitting mechanism, wherein the tube core supporting mechanism is arranged at the front end of the fixing plate; the slitting mechanism is arranged outside the tube core supporting mechanism; the slitting mechanism isarranged at the rear end of the fixing plate; the tube core supporting mechanism comprises a fixing cylinder, a telescopic plate, a supporting plate, an anti-sliding plate and a limiting branched chain; the slitting mechanism comprises a rotary motor, a rotary plate, an adjusting cylinder, an adjusting frame, a slitting tool rest and a protective branched chain; the limiting branched chain comprises an installation plate, a regulating cylinder, a limiting block and a limiting frame; and the protective branched chain comprises a sliding plate, a connecting block, a working plate, a buffer spring, a protective plate and a rolling column. According to the slitting device and the slitting method thereof, the problems of poor flatness of the cut, easy extrusion deformation of the tube core, potential safety hazard in manual blanking and the like in existing slitting process of a blister film roll are solved.

The invention relates to the technical field of articles of daily use, and discloses a device capable of automatically moving by utilizing dead weights of beverages and convenient to move and fix. Thedevice comprises a refrigerator body; the inside of the refrigerator body is movably connected with placement frames; the left side of the refrigerator body is movably connected with a refrigerator door; the inside of the refrigerator door is movaly connected with taking frames; the insides of the taking frames are movably connected with power rods; the outsides of the power rods are sleeved withpower springs; the left side outside the refrigerator body is fixedly connected with a freezer; and the lower part of the refrigerator body is fixedly connected with a movement frame. After beverageson the placement frames are taken away, the placement frames are ascended under the action of elastic forces of the springs, and then racks of the placement frames are separated from power gears so as to facilitate placing beverages again, thereby achieving an effect of facilitating taking beverages and ensuring that in the taking process, other beverages cannot fall out of a refrigerator due tocarelessness to cause accidental damage.
