The body 1 comprises a hexagonal plate 101, two first jacks 1011 are formed in the hexagonal plate 101, a conical block 102 is fixedly connected to the bottom of the hexagonal plate 101, threads 1021 are formed on the outer surface of the conical block 102, and a threaded rod 103 is fixedly connected to the bottom of the conical block 102.

The mounting member 202 includes a mounting plate 2021, a chute 2022 is disposed on the mounting plate 2021, and a first through hole 2023 is disposed in the middle of the mounting plate 2021.

The gasket assembly 203 includes a sleeve gasket 2031, and the sleeve gasket 2031 is formed of a tapered gasket and a cylindrical gasket positioned within and unsecured from the first port 2023, with the bottom of the cylindrical gasket extending beyond the mounting plate 2021 and having a first gasket 2032 disposed on the outer surface of the sleeve gasket 2031.

The positioning assembly 205 comprises a rotating plate 2051, a second through hole 2052 corresponding to the first through hole 2023 is formed in the rotating plate 2051, a fixed block 2053 is fixedly connected to one side of the rotating plate 2051, a sliding block 2054 rotationally connected with the sliding groove 2022 is fixedly connected to the bottom of the rotating plate 2051, a second gasket 206 is arranged at the top of the rotating plate 2051, a third through hole 2061 corresponding to the second through hole 2052 is formed in the second gasket 206, the second through hole 2052 and the third through hole 2061 can form a cone frustum, the cone frustum corresponds to a conical gasket and is fixedly connected, and two second jacks 207 corresponding to the plug rods 208 are formed in the rotating plate 2051 and the second gasket 206.

The top inner diameter of the tapered washer is smaller than the top diameter of the tapered block 102 and the bottom inner diameter of the tapered washer is the same as the inner diameter of the tapered block 102.

The fixing bolt 3 comprises a screw 301 in threaded connection with a jack 1011, and two symmetrical ears 302 are fixedly connected to the top of the screw 301.

In use, the anti-drop member 201 is aligned with the mounting hole on the workpiece, and is lowered until the first gasket 2031 is placed on the workpiece, during which process the excess sleeve gasket 2031 is inserted into the mounting hole, at which time the first, second and

third openings

2023, 2052, 2061 on the anti-drop structure 2 are positioned in up-down alignment with the mounting hole, and then the plunger 208 is inserted in alignment with the second receptacle 207.

The body 1 is then aligned with the through hole, while the first insertion hole 1011 is aligned with the insertion rod 208 and moved downward, and during this process the insertion rod 208 is inserted into the first insertion hole 1011 so that the body 1 is perpendicular to the workpiece, and when the bottom of the body 1 is inserted into the sleeve gasket 2031, since the thread on the threaded rod 103 is protruded, the diameter of the thread is larger than the inner diameter of the cylindrical gasket, and it is necessary to rotate the body 1 using a tool.
