Detailed Description

The invention is further described with reference to the following drawings and specific examples, but not to be construed as being limited thereto;

as shown in fig. 1, 2 and 3, the resettable lifting rod base comprises a rod base 1, a support rod 3, a resetting block 2, two positioning pins 4, two compression springs 10, two compression screws 5, a resetting jacking screw 6, a wave ball screw 8, a locking screw 7 and a magnet 9.

As shown in fig. 4, 5, 6 and 7, the rod base 1 has a central hole 12 with an inner wall opened with an axial arc-shaped groove 11, an outer cylindrical surface 19 of the rod base 1 has a locking screw hole 13 and a supporting screw hole 14 in the radial direction, and the top of the rod base 1 has two pin holes 17 to match with the small cylindrical end 42 of the positioning pin 4; as shown in fig. 3, the bottom of the rod seat 1 is provided with a plurality of blind holes 16 for placing the magnets 9; a circumferential ring groove 15 is formed on an outer cylindrical surface 19 of the rod seat 1 close to the bottom; the upper part of the outer cylindrical surface 19 of the rod seat 1 is provided with a scribed line 18, and the outer wall of the reset block 2 is provided with a scribed line 21 which is collinear with the scribed line 18 of the rod seat 1;

as shown in fig. 6, the reset block 2 has a central hole 23 with an inner wall provided with an axial arc-shaped groove 21, a jacking screw hole 24 is radially arranged on the outer wall of the reset block 2, two reset holes 28 are arranged on the end surface of the reset block 2, and the reset holes 28 are a screw hole 25, a large unthreaded hole 26 and a small unthreaded hole 27 sequentially from top to bottom along the axial direction; as shown in fig. 2 and 7, the positioning pin 4 has a large cylindrical end 41 and a small cylindrical end 42, which are respectively disposed in the large unthreaded hole 26 and the small unthreaded hole 27; as shown in fig. 2, the pressing screw 5 elastically presses the positioning pin 4 through the pressure spring 10 placed in the large unthreaded hole 26;
