[0024] The side surface close to the gear 207 of the pushing plate 204 is provided with a toothed rail which is engaged with the gear 207, the top end of the pushing plate 204 is provided with a connecting rod 209, the top end of the connecting rod 209 is fixedly connected with the pushing plate 204, the bottom end of the connecting rod 209 extends to the inside of the fixed plate 201 and is in contact with the fixed plate 201, both sides of the gear 207 are provided with a support 210 which is fixedly connected with the fixed plate 201, the rotating rod 205 penetrates through the support 210, both sides of the lifting plate 203 are provided with a round rod 211 which is fixedly connected with the positioning plate 202, the end of the round rod 211 away from the positioning plate 202 is provided with a torsion spring 212, the front surface of the fixed plate 201 is provided with a sliding groove 213, the lifting plate 203 is movably connected with the sliding groove 213, and the bottom end of the connecting rod 209 is provided with an electric push rod 214.

[0025] Please refer to Figure 1 and 4 Both ends of the base 1 are provided with the mounting plate 4, the bottom end of the mounting plate 4 is matched with the hole 3, and the top of the mounting plate 4 is fixedly provided with the handle 5.

[0026] When working, first use the electric push rod 214 to make the connecting rod 209 and the lifting plate 203 move upwards, and the distance between the two is enlarged, which is convenient for subsequent operation. Place the valve body on the base 1, and between the two positioning plates 202. After placing, use the electric push rod 214 to make the connecting rod 209 move downwards again, and the pushing plate 204 fixedly connected with the connecting rod 209 also moves downwards at the same time, and the tooth rail on the surface also moves downwards. Since the gear 207 is engaged with the gear 207, the rotation of the gear 207 can make the tooth rail and the pushing plate 204 move downwards, and the connecting rod 209 above the pushing plate 204 and the lifting plate 203 below move downwards. Since the lifting plate 203 is movably connected with the sliding groove 213, the lifting plate 203 can move downwards along the sliding groove 213, and the lifting plate 203 can move linearly. The bottom end of the connecting rod 209 is in contact with the fixed plate 201, and the downward movement of the connecting rod 209 ensures the downward movement of the lifting plate 203, so that the lifting plate 203 is in contact with the valve body, which is convenient for subsequent operation. During the rotation of the gear 207, since the gear 207 is fixedly connected with the rotating rod 205, the rotating rod 205 rotates together with the gear 207, and the rotating rod 205 penetrates through the two supports 210 and is in contact with the supports 210, which ensures the rotation of the rotating rod 205. Because the rotating rod 205 is screwedly connected with the threaded rod 206, the rotation of the rotating rod 205 can make the two threaded rods 206 move at the same time. The threads on the surfaces of the two threaded rods 206 are oppositely arranged, so that the rotation of the rotating rod 205 can make the two threaded rods 206 move at the same time, and push the sliding rod 208 to move. Since one end of the sliding rod 208 is slidably connected with the fixed plate 201, the sliding rod 208 can move along the fixed plate 201. During the movement of the sliding rod 208, the sliding rod 208 can be in contact with the positioning plate 202. Because the positioning plate 202 is movably connected with the fixed plate 201 through the round rod 211, the sliding rod 208 can make the positioning plate 202 and the round rod 211 rotate, so that the torsional spring 212 connected with the round rod 211 is deformed, the bottom end of the positioning plate 202 moves towards the middle of the base 1, and the positioning plate 202 changes from a vertical state to an inclined state. The positioning plate 202 can position the valve body, and the mounting plate 4 is in contact with the base 1, so that the mounting plate 4 can be separated from the base 1, combined with other holes 3, and rotated again. The inclination angle of the positioning plate 202 is adjusted by combining the mounting plate 4 with the hole 3, and the positioning plate 202 is blocked by the mounting plate 4 to prevent the positioning plate 202 from rotating, which is convenient for adjusting the positioning plate 202 again.

[0027] Meanwhile, the contents not described in detail in the specification are all prior art known to those skilled in the art.
