A base support platform 104 is fixed to the top of the base support 101, and a fluid metering pump body 105 is installed on the top of the base support platform 104;

[0030] The mounting unit 200 includes a fluid metering pump base 201 fixed to the bottom of the fluid metering pump body 105, and mounting holes 202 are opened at the four corners of the fluid metering pump base 201. Four cylinders 203 are arranged above the base support platform 104, and a positioning column 204 that can be embedded in the mounting hole 202 is slidably connected in the cylinder 203. A threaded rod 205 is rotatably connected to the top of the positioning column 204, and the threaded rod 205 penetrates the cylinder 203 and is threadedly connected to the cylinder 203. An annular pressure plate 204a is fixed to the outer side of the positioning column 204, and the diameter of the annular pressure plate 204a is larger than the diameter of the mounting hole 202. An adjustment component 206 for adjusting the position of the cylinder 203 is arranged on the base support platform 104.

[0031] In addition, two rectangular plates 208 are arranged above the base support platform 104, and a rectangular groove 209 is opened in the rectangular plate 208. Two moving blocks 210 are slidably connected in the rectangular groove 209, and the inner walls on both sides of the moving blocks 210 are in contact with the inner walls on both sides of the rectangular groove 209.

[0032] In addition, the adjustment component 206 includes a travel groove 2061 opened in the base support platform 104, and a bidirectional screw 2062 is rotatably connected in the travel groove 2061.

[0033] During use, since the sizes of the fluid metering pump bodies 105 of different specifications are different, the sizes of the fluid metering pump bases 201 at the bottom thereof are also different. When installing the fluid metering pump bodies 105 of different specifications, firstly place the fluid metering pump base 201 at the bottom of the fluid metering pump body 105 on the base support platform 104, and then rotate the bidirectional screw 1 2062 to drive the L-shaped plate 2063 to move, and when the L-shaped plate 2063 moves, it drives the rectangular plate 208 to move, so that the two rectangular plates 208 are close to each other, and then rotate the bidirectional screw 2062 to drive the L-shaped plate 2063 to move. 64 drives the moving block 210 to move, and then drives the connecting plate 211 and the cylinder 203 to move, that is, the position of the positioning column 204 is adjusted, the positioning column 204 is adjusted to the top of the mounting hole 202, and then the threaded rod 205 is rotated to drive the positioning column 204 to move downward, when the bottom of the positioning column 204 is embedded in the mounting hole 202, and the annular pressure plate 204a and the top of the fluid metering pump base 201 are against each other, that is, the fluid metering pump body 105 is fixed on the base support platform 104, and different specifications of fluid metering pump bodies 105 can be fixed.

[0035] It should be noted that there is a distance between the bottom of the rectangular plate 208 and the base support platform 104, and the distance is greater than the thickness of the fluid metering pump base 201, so that after the fluid metering pump base 201 is placed on the base support platform 104, the rectangular plate 208 can move above the fluid metering pump base 201, and when the rectangular plate 208 moves, the bracket 213 moves accordingly in the stroke groove 214, and due to the setting of the guide rod 215, the bracket 213 can move back and forth stably in the stroke groove 214, thereby constraining the moving path of the rectangular plate 208 and ensuring its stable back and forth movement.

[0036] It should be noted that the above embodiments are only used to illustrate the technical solution of the utility model rather than to limit it. Although the utility model has been described in detail with reference to the preferred embodiments, ordinary technicians in the field should understand that the technical solution of the utility model can be modified or replaced by equivalents without departing from the spirit and scope of the technical solution of the utility model, which should be included in the scope of the claims of the utility model.
