Detailed ways

The following will clearly and completely describe the technical solutions in the embodiments of the present invention with reference to the drawings in the embodiments of the present invention. Based on the embodiments of the present utility model, all other embodiments obtained by persons of ordinary skill in the art without making creative efforts belong to the scope of protection of the present utility model.

Please refer to Fig. 1 to Fig. 4, the utility model provides a kind of technical scheme: a kind of stretching device, comprise control box 1, the top of control box 1 inner side wall is fixedly connected with limit ring 2, the inside of limit ring 2 is slidably connected with rack 3, the outer surface of rack 3 is meshed with gear 4, one side of the lower surface of rack 3 is fixedly connected with slider 5, and one side of slider 5 is fixedly connected with support plate 6. The bar 3 slides in the limit ring 2, thereby driving the support plate 6 to move to both sides through the slider 5, realizing the function of stretching the epidermis, reducing the physical consumption of the medical staff, saving time and effort, and at the same time, the stretching force on both sides is the same, so as to avoid causing damage to the patient. The middle part of the upper surface of the control box 1 is rotatably connected with a control block 9, and one end of the control block 9 is fixedly connected to the upper surface of the gear 4. Both sides of the upper surface of the control box 1 are provided with a square groove, and the inside of the square groove is fixedly connected with a glass 10.
