The autism eye movement track recognition instrument limits the head position of the patient through the swingable head limiting mechanism, the swing of the head of the patient can reduce the uncomfortable feeling, the eye movement tracking camera is driven to move synchronously through a power transmission assembly, the eyes of the patient can be kept facing the camera during the test process, the eyes of the patient are prevented from deviating from the shooting range of the camera, and the eye movement tracking camera is prevented from moving and lagging behind when the head of the patient swings, so that the shooting of the eyes is not delayed, and the accuracy of collecting the eye movement track of the patient is ensured.

The invention relates to the technical field of mark pens, in particular to an anti-layering multicolor propylene mark pen which solves the problems that when the mark pen is used, ink is often settled or condensed due to the fact that the mark pen is not used for a long time, the mark pen cannot be used for writing, and the ink cannot be continuously added into the mark pen after the ink is used up. An ink bin is arranged in the mark pen shell, and the ink bin is filled with layering-resistant multi-color propylene ink. The anti-layering multicolor propylene ink comprises the following components in percentage by mass: 15-22% of titanium dioxide, 0-6% of color paste, 50-60% of acrylic resin, 30-50% of water, 0.5-3% of water-soluble resin, 0.03-2% of a surfactant, 7-12% of other auxiliaries, 3-6% of an interphase regulator and 2-3% of a penetrant. Through the synergistic effect of the penetrant, the high-molecular polymer and the like added into the anti-layering multicolor propylene ink, the problem of edge permeation generated in the permeation process is solved.

The invention provides a pet feeding device which comprises a base, a pedal, a coupling rod, a food basin and a backflow plate, a basin groove is formed in one side of the base, the pedal is rotatably installed on the base, the coupling rod is slidably assembled on the base and movably connected with the pedal, the food basin is movably assembled in the basin groove, a backflow hole is formed in the middle of the food basin, and the backflow plate is arranged in the base. According to the pet food output device, the pedal is arranged at one end of the base, the food basin of a hollow structure is arranged in the base, output of pet food can be controlled according to the action that a pet presses the pedal, and the food can be quantitatively output according to the weight of the pet; and after the pet finishes eating, the residual food in the food basin can be recycled, so that the pet food is prevented from being damped and mildewed in the air or winged insects are prevented from being attracted.

The utility model discloses a rehabilitation assistive device for training mild cognitive impairment of old people, which comprises a fixed disc, and a bearing plate is mounted at the lower end of the front side of the fixed disc; the supporting plate is mounted at the lower end of the bearing plate, and mounting screws are arranged in through holes formed in the supporting plate; the observation assembly is arranged on the fixed disc; the rotating assembly is arranged at the rear end of the fixed disc; the cognitive card is attached to a groove formed in the rotating assembly.
