The lower ends of the two screw rods 4 are rotatably arranged on the left and right ends of the base 1 respectively. The transmission shaft 8 is rotatably arranged on the upper side of the base 1, and the middle part is connected to the motor 5 installed on the base 1 through a gear transmission. The transmission shaft 8 is located between the two screw rods 4 and the two ends are respectively connected to the bottom of the two screw rods 4 through a bevel gear transmission. The left and right sides of the circular lifting seat 2 are respectively integrally formed with cross arms 3, and the two cross arms 3 are respectively threadedly sleeved on the two screw rods 4; The clamp includes a cylinder 6, a telescopic structure and a clamping plate 7. There are three clamping plates 7 and they are evenly arranged on the inner side of the cylinder 6. The clamping plate 7 is an arc-shaped plate structure, and an anti-skid layer 15 is arranged on its inner wall. The anti-skid layer 15 is a rubber layer. In order to allow each clamping plate 7 to clamp the motor equipment more firmly, the clamping plate 7 is connected to the cylinder 6 through a telescopic structure. The telescopic structure includes a threaded rod 11, a bobbin 12 and a limiting light rod 13; the bobbin 12 is fixed to the back of the middle part of the clamping plate 7, and the bobbin 12 is threadedly sleeved on the threaded rod 11. The threaded rod 11 passes through the single-side wall of the bobbin 12 and is threadedly connected to the wall. A handwheel 14 is fixed to one end of the threaded rod 11 located on the outer side of the bobbin 12. The limiting light rods 13 are fixed to the left and right ends of the back side of the clamping plate 7 respectively, and the limiting light rods 13 movably pass through the single-side wall of the bobbin 12; The cylinder 6 is rotatably arranged inside the ring lifting seat 2 and is fixed inside the ring lifting seat 2 by a positioning structure.
