DETAILED DESCRIPTION

[0015] The following are specific embodiments of the present invention and the accompanying drawings to further describe the technical solution of the present invention, but the present invention is not limited to these embodiments.

[0016] like Figure 1 , Figure 2As shown, the high stability electric hoist comprises an electric hoist as a whole 1, on which a slide rail 2 is arranged, and the electric hoist as a whole 1 slides on the slide rail 2 through a moving seat 16, and the electric hoist as a whole 1 is provided with a fixed seat 3 fixed to the moving seat 16, when the electric hoist as a whole 1 is fixed, the upper end of the fixed seat 3 is tightly attached to the lower end surface of the moving seat 16, and the fixed seat 3 is fixedly provided with a plurality of fixed columns 4 penetrating the connecting seat, and the lower end of the moving seat 16 is provided with a connecting portion 5, and the connecting portion 5 is provided with an opening matched with the fixed column 4, so that The fixed column 4 is provided with a positioning assembly 6 for positioning, and the positioning assembly 6 is composed of a positioning member 7 and a return spring. The positioning member 7 can be extended and retracted on the fixed column 4 under the action of the return spring. Several fixed columns 4 are provided with fixing rings 8 for shock absorption and strengthening the connection stability. The left and right sides of the slide rail 2 are provided with slide grooves 10 for the moving seat 16 to slide. The moving seat 16 is provided with two sliding parts 9 matching the slide grooves 10. The sliding part 9 and the moving seat 16 are an integrally formed structure, and the shape of the slide groove 10 is the same as that of the sliding part 9.
