The clamp 7 is used to fix the brake pump on the fixed rod 3, and the clamp 7 can change its position, so that the position of the brake pump on the fixed rod 3 is adjustable, which is convenient for use. In addition, the push rod 2 connected to the piston in the brake pump is in contact with the slider 9. If it is necessary to push or pull the push rod 2, the force is directly applied to the slider 8. The slider 9 is installed on the slider 8, so the slider 8 will drive the slider 9 and then drive the push rod 2 to move. The slider 8 is slidably connected to the fixed rod 3. Therefore, even if the slide rod 8 is subjected to a force in an inclined direction, the force will not be applied to the push rod 2, which is convenient for use and achieves the purpose of protecting the push rod 2 and the brake pump body 1. The brake pump body 1 is placed in the V-shaped groove 11 and fixed by the clamp 7. When it is subjected to the pushing force of the push rod 2 for a long time, the brake pump body 1 may move. At this time, the limiting mechanism can be used to further strengthen the restriction on the brake pump body 1 and improve the stability during use.
