Detailed Description

The following describes the embodiments of the present invention in further detail with reference to the accompanying drawings.

By figure 1 to 4, including dull and stereotyped 1, dull and stereotyped 1 left and right sides is equipped with backup pad 2 of direction from top to bottom respectively, two backup pad 2 upper ends are equipped with about one direction and the ascending U template 3 of opening, the rectangle ring 4 that link up around the left and right sides is equipped with respectively in the U template 3, sliding connection has H type piece 5 in the

rectangle ring

4, 5 upper ends of H type piece are equipped with the type of falling L template 6, back of the body about two type of falling L templates 6 back to back mutually, the type of falling L template 6 upper end is equipped with grip block 7 of direction from top to bottom, be equipped with direction from top to bottom and gliding pull rod 8 from top to bottom on the U template 3, the left and right sides of pull rod 8 upper end articulates respectively has the connecting rod 9 of a plurality.

In order to enable the pull rod 8 to slide up and down, a horizontal fixing plate 10 is arranged between the two supporting plates 2, and the lower end of the pull rod 8 is rotatably connected with a screw rod 11 which is axially arranged up and down and is in threaded connection with the fixing plate 10.

In order to prevent the holding plate 7 from hurting the face of the child, the opposite ends of the two holding plates 7 are respectively provided with cotton pads 12.

In order to increase the comfort of children, the upper end of the U-shaped plate 3 is provided with a chin pad 13 positioned between the two clamping plates 7 through a connecting plate, and the upper end surface of the chin pad 13 is an arc-shaped surface with an inward concave part in the middle.

For better using effect, the flat plate 1 is provided with an expansion link 14 which is positioned at the rear part of the support plate 2 and is in the vertical axial direction, the upper end of the expansion link 14 is provided with a soft seat 15, and the upper side of the expansion link 14 is in threaded connection with a bolt knob 16 which can be in contact with the inner end of the expansion link.

In order to rotate the screw rod 11, the lower end of the screw rod 11 penetrates through the fixing plate 10 and is coaxially provided with a hand wheel 17.

When the utility model is used, firstly, the bolt knob 16 is rotated anticlockwise to enable the bolt knob 16 to be separated from the inner end of the telescopic rod 14, then the soft seat 15 is pulled upwards, the soft seat 15 drives the telescopic rod 14 to extend until the height of the soft seat 15 is matched with the height of a child, the bolt knob 16 is rotated clockwise to enable the bolt knob 16 to be in close contact with the inner end of the telescopic rod 14, and at the moment, the bolt knob 16 fixes the telescopic rod 14 at the current length;

the child sits on the soft seat 15 with the face facing right, the child places the chin on the chin pad 13, at the moment, the hand wheel 17 rotates anticlockwise, the hand wheel 17 drives the screw rod 11 to rotate anticlockwise, the screw rod 11 moves downwards while rotating due to the fact that the screw rod 11 is in threaded connection with the fixing plate 10, the screw rod 11 drives the pull rod 8 to slide downwards on the U-shaped plate 3, the pull rod 8 drives opposite ends of the connecting rods 9 on the left side and the right side to swing downwards, the connecting rod 9 on the left side drives the H-shaped block 5 to slide right in the rectangular ring 4 through the inverted L-shaped plate 6 on the left side, the connecting rod 9 on the left side drives the clamping plate 7 on the left side to move rightwards, the connecting rod 9 on the right side drives the H-shaped block 5 to slide left in the rectangular ring 4 through the inverted;
