[0027] A mouth-opening support assembly 2 is arranged below the lifting frame 101, and a lifting mechanism 3 is arranged on the top surface of the extension rod 103;

[0028] Among them, the mouth-opening support assembly 2 includes a chute 201 opened on the bottom surface of the extension rod 103, a slider 202 is slidably connected in the chute 201, a V-shaped connecting rod 203 is fixedly installed on one side of the slider 202 close to the lifting frame 101, a screw rod bin 204 is fixedly installed at the end of the V-shaped connecting rod 203, and bent rods 211 are symmetrically slidably connected to the outside of the screw rod bin 204, and a U-shaped support plate 212 is fixedly connected to the end of the bent rod 211; when the U-shaped support plate 212 moves to both ends of the screw rod bin 204, the width of the mouth is greater than the maximum width of the lifting frame 101. By horizontally and obliquely shaking the impression-taking main body 1, it is convenient for both ends of the lifting frame 101 to be inserted into the oral cavity in sequence. After the U-shaped support plate 212 is opened, it can form a snap fit with the corners of the mouth.

[0029] A double-headed screw rod 207 is rotatably installed inside the screw rod bin 204, threaded sleeves 208 are symmetrically threaded on both sides of the double-headed screw rod 207, a worm gear 209 is fixedly connected to the middle of the double-headed screw rod 207, and the worm gear 209 is meshed with a worm 210; a motor housing 205 is fixedly installed on the outside of the screw rod bin 204, a micro motor 206 is fixedly installed inside the motor housing 205, the micro motor 206 penetrates through the screw rod bin 204 and is fixedly connected to the worm 210, and the threaded sleeve 208 is fixedly connected to the bent rod 211; the worm 210 is connected to the inside of the screw rod bin 204, and the rotation of the double-headed screw rod 207 can drive the threaded sleeve 208 to move.

[0030] A rubber pad 213 is fixedly installed on the inner side of the U-shaped support plate 212; the rubber pad 213 can reduce the friction between the U-shaped support plate 212 and the corners of the mouth and reduce the pain during impression-taking.
