Detailed Description

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

The bending device is characterized by comprising a horizontal rectangular plate 1, a first U-shaped rod 2 with a left end and a right end and a downward opening is arranged at the upper end of the rectangular plate 1, a second U-shaped rod 3 capable of sliding up and down is arranged at the upper end of the first U-shaped rod 2, front and back axial sliding shafts 4 are respectively arranged at the left end and the right end of the second U-shaped rod 3, bending rods 5 are respectively and rotatably connected to the left side and the right side of the upper end of the first U-shaped rod 2 through the shaft, the two bending rods 5 are opposite to each other in left and right, waist-shaped grooves 6 which are communicated along the length direction and front and back are respectively arranged at the upper sides of the two bending rods 5, the two waist-shaped grooves 6 are respectively and slidably connected with the sliding shafts 4 of the corresponding sides of the two waist-shaped grooves, arc-shaped plates 8.

In order to limit the second U-shaped rod 3 to only slide up and down, a rectangular box 9 with a downward opening is arranged at the upper end of the first U-shaped rod 2, and the second U-shaped rod 3 is positioned in the rectangular box 9 and is in sliding connection with the rectangular box 9.

In order to drive the second U-shaped rod 3 to slide up and down, the upper end of the first U-shaped rod 2 is provided with a fixing block 10 in the front-back direction, a screw rod 11 in the vertical axial direction is rotatably connected between the fixing block 10 and the upper side wall of the rectangular box 9, and the screw rod 11 is in threaded connection with the second U-shaped rod 3.

For better use effect, the opposite surfaces of the two arc plates 8 are respectively provided with an arc soft rubber pad 12.

In order to make the patient more comfortable, the rectangular plate 1 is provided with a headrest 13 positioned in front of the first U-shaped bar 2.

In order to rotate the screw rod 11 conveniently, the upper end of the screw rod 11 penetrates through the upper side wall of the rectangular box 9 and is coaxially provided with a hand wheel 14.

When the utility model is used, the device is firstly placed on an operating bed, the lower end face of a rectangular plate 1 is tightly attached to the upper end face of a bed plate, then a hand wheel 14 is rotated clockwise, the hand wheel 14 drives a screw rod 11 to rotate clockwise, the screw rod 11 drives a second U-shaped rod 3 to slide upwards in a rectangular box 9, the second U-shaped rod 3 drives two sliding shafts 4 to slide upwards, the two sliding shafts 4 slide in waist-shaped grooves 6 corresponding to the sliding shafts respectively, the two sliding shafts 4 drive two bending rods 5 to swing outwards, the two bending rods 5 drive arc-shaped plates 8 on the corresponding sides to swing outwards through connecting blocks 7 respectively, and when the distance between the two arc-shaped plates 8 can put down the head of a patient, the hand wheel 14 stops rotating;
