It clamps the electronic water pump with a clamping assembly and places at least part of the mounting sleeve of the blocking assembly inside the water pump inlet. The movement of the stop rod drives the baffle to pass through the protective bracket and cooperate with the outer edge of the blade, thereby physically blocking the impeller of the electronic water pump. It can achieve electronic water pump stall without disassembly. At the same time, it does not require a power source and can achieve electronic water pump stall by manpower only, with less restriction on the application scenario.

Two racks 6 are symmetrically arranged on the rear surface of the first baffle 3 and slidably connected to the second baffle 5. Two drive components are provided on the rear surface of the second baffle 5. Each drive component includes two first support blocks 7 and a gear 8. The gear 8 is disposed between the two first support blocks 7 and rotatably connected to them. The gear 8 is connected to the adjacent racks 6. The transmission is driven by the meshing of two gears 8. One surface of each of the two first support blocks 7 is provided with a first locking device. The front surface of the first baffle 3 is provided with two second support blocks 9. The front surfaces of the two second support blocks 9 are provided with second locking devices. The surfaces of the two second support blocks 9 are provided with first sliding holes 10. The two first sliding holes 10 are slidably connected to sliders 11. The middle of the front surface of sliders 11 is provided with locking blocks 12. The surface of locking blocks 12 is provided with third locking devices. The front surface of locking blocks 12 is provided with second sliding holes 13. The inside of the second sliding holes 13 is slidably connected to a stop rod 14. The rear end of the stop rod 14 is provided with a stop piece 15.

[0021] The first locking device includes a rocker arm 16, which is fixedly connected to the front surface of the gear 8 and rotatably connected to the front surface of the first support block 7. One end of the rocker arm 16 is provided with a handle 17, and the surface of the first support block 7 is provided with an annular frame 18. The surface of the annular frame 18 is provided with a plurality of snap-fit ​​holes 19 evenly arranged in an annular shape. The rocker arm 16 is threadedly connected with a fixing bolt 20, and one end of the fixing bolt 20 extends into the snap-fit ​​hole 19.

[0022] The surface of the fixing bolt 20 is evenly provided with multiple anti-slip ridges. The anti-slip ridges serve to prevent slipping.

[0023] The second locking device includes a first rotating cap 21, and a first abutting rod 22 is provided on the rear surface of the first rotating cap 21. The first abutting rod 22 is threadedly connected to the second support block 9, and one end of the first abutting rod 22 extends into the first sliding hole 10.

[0024] The third locking device includes a second rotating cap 23, and a second abutting rod 24 is provided on the rear surface of the second rotating cap 23. The second abutting rod 24 is threadedly connected to the locking block 12, and one end of the second abutting rod 24 extends into the second sliding hole 13.

[0025] Limiting blocks 25 are provided at both ends of the slider 11. The limiting blocks 25 serve to limit the slider 11.

[0026] Working principle: During testing, the electronic water pump body 1 is placed between the first baffle 3 and the second baffle 5. The first locking device is set up so that by shaking the handle 17, the rocker arm 16 drives the gear 8 to rotate. Through the meshing transmission of two adjacent gears 8, the rotation of another gear 8 is driven. The two gears 8 mesh with their corresponding racks 6, thereby pulling the first baffle 3 closer to the electronic water pump body 1, so that the first baffle 3 and the second baffle 5 clamp the electronic water pump body 1. Then, the fixing bolt 20 is threadedly connected to the rocker arm 16, so that the fixing bolt 20 extends into the snap-fit ​​hole 19 to fix the gear 8. In summary, the first locking device, by shaking the handle 17, can clamp the first baffle 3 and the second baffle 5 to the electronic water pump body 1. This operation is time-saving and labor-saving, and improves work efficiency.

[0027] When the blades of the electronic water pump body 1 are engaged by the baffle 15, the position of the blades can be observed through the test through-hole 4. Then, the slider 11 is moved left and right until it reaches the designated position. The second locking device, by screwing on the first rotating cap 21, causes the first abutment rod 22 to press against the slider 11, thus fixing the slider 11. The baffle 14 moves along the second sliding hole 13 towards the test through-hole 4, and the baffle 15 passes through the test through-hole 4 and the water pump inlet 2. The baffle 15 then engages with the blades of the electronic water pump body 1. The third locking device, by screwing on the second rotating cap 23, causes the second abutment rod 24 to extend into the second sliding hole 13, allowing the electronic water pump body 1 to be tested. In summary, observing the position of the blades of the electronic water pump body 1 through the test through-hole 4 facilitates observation of the gaps between adjacent blades on the electronic water pump body 1. The baffle 15 will not bump into the blades, avoiding damage to them.
