[0021] Please refer to Figure 1 - Figure 3As shown, a kind of automobile water pump with mechanical flexible gear function, including pump body 1, pipe 2 is fixedly connected with one side of the top end of pump body 1, pump body 1 bottom end is provided with mounting seat 3, fixed mechanism is provided at the top of mounting seat 3, fixed mechanism includes two groups of moving grooves 4, and two groups of moving grooves 4 are opened in the top of mounting seat 3 two sides, screw rod 100 is provided in moving groove 4, and the both ends of screw rod 100 are rotatably connected with one end of two groups of moving grooves 4 penetrating mounting seat 3, one end of mounting seat 3 is provided with hexagonal column 9, the output shaft of hexagonal column 9 is fixedly connected with one end of screw rod 100 penetrating mounting seat 3, and the both ends of screw rod 100 are screw-connected with moving block 5, moving block 5 is fixedly connected with connecting column 6, and one end of connecting column 6 is fixedly connected with clamping block 7;

[0022] When working, the installation of pump body 1 can be realized by placing pump body 1 on the top of mounting seat 3 through the structural design of fixed mechanism, rotating hexagonal column 9 drives screw rod 100 to rotate, the threads opened at the both ends of screw rod 100 are opposite, so two groups of moving blocks 5 will move towards each other, to drive clamping block 7 to move and enter clamping groove 8 to tightly contact pump body 1, so as to achieve the ability of conveniently fixing pump body 1, and the functions of subsequent pump body 1 maintenance installation and disassembly are facilitated.

[0023] Further, as shown in the figure, Figure 1 Pump body 1 is provided with clamping groove 8 outside, the size of clamping block 7 is matched with clamping groove 8, and clamping block 7 is in clamping groove 8;

[0024] When working, when two groups of clamping blocks 7 move to the inside of clamping groove 8, pump body 1 is resisted by two groups of clamping blocks 7, so as to complete the fixing.

[0025] Further, as shown in the figure, Figure 3 Moving block 5 is in moving groove 4, and the size of moving block 5 is matched with moving groove 4;

[0026] When working, the rotation of screw rod 100 will make moving block 5 have the same rotating trend, because the size of moving block 5 is matched with moving groove 4, so the rotating trend of moving block 5 will be hindered by moving groove 4, and because moving block 5 is screw-connected with screw rod 100, so moving block 5 can move on screw rod 100 while screw rod 100 rotates.

[0027] Further, as shown in the figure, Figure 3 The bottom end of mounting seat 3 is fixedly connected with mounting plate 10, and screw 11 penetrates mounting plate 10;
