Detailed Description

The technical solutions in the embodiments of the present invention will be described clearly and completely with reference to the accompanying drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only some embodiments of the present invention, not all embodiments. Based on the embodiments in the present invention, all other embodiments obtained by a person skilled in the art without creative work belong to the protection scope of the present invention.

Referring to fig. 1-4, the present invention provides a technical solution: the utility model provides a sprayer clamp plate of diesel engine, including clamp plate 2, the equal shaping in both ends of clamp plate 2 has two risers 1, the one end that clamp plate 2 was kept away from to 1 bottom surfaces of riser is provided with arch 9, be formed with centre gripping groove 3 between two risers 1 of 2 same ends of clamp plate, centre gripping groove 3 is the U-shaped groove, hemispherical counter bore 6 has been seted up at the middle part of 2 upper surfaces of clamp plate, vertical through-hole 4 that is used for the screw rod to pass through of offering in the counter bore 6, the upper surface of clamp plate 2 is by riser 1 to counter bore 6 direction highly degressive curved concave surface 7 in.
