Detailed Description
The following describes the embodiments of the present invention in further detail with reference to the drawings.
As shown in fig. 1-5, the invention comprises a frame 1, wherein the frame 1 is shaped like a Chinese character 'kou', a screw rod 2 is vertically arranged, two ends of the screw rod 2 are rotatably connected with the frame 1, two guide rods 3 which are arranged in parallel are arranged at two sides of the screw rod 2, the upper end and the lower end of the guide rods 3 are fixedly connected with the frame 1, a lifting frame 4 is connected with the screw rod 2 through a screw rod nut 5, two sides of the lifting frame 4 are slidably connected with the two guide rods 3, and the lifting frame 4 is driven by the screw rod 2 to move up and down along the two guide rods 3. The upper end of lead screw 2 is equipped with spindle nose 21, and spindle nose 21 and lead screw 2 are integrated into one piece structure, and the lower part of spindle nose 21 is equipped with the columniform cavity 22 coaxial with lead screw 2, and the upper portion of spindle nose 21 is link 23, and link 23 is equipped with the through-hole 25 coaxial with cavity 22 to link 23 is equipped with a plurality of radial evenly distributed's logical groove 24, logical groove 24 axial intercommunication cavity 22, and the quantity of logical groove 24 can be determined according to actual need, and in this embodiment, link 23 of spindle nose 21 is equipped with 6 logical grooves 24. The motor 6 and the speed reducer 7 are arranged on the frame 1, the driving shaft 8 is connected with the speed reducer 7, a radial pin shaft 11 is fixedly arranged at the lower end of the driving shaft 8, the pin shaft 11 is fixed on the driving shaft 8 by a set screw 12, and a shaft shoulder 9 is arranged in the middle of the driving shaft 8.
