Preferably, a chamfer is formed at the edge of the inlet at the bottom end of the anti-loosening pin mounting hole.
Preferably, the anti-loosening pin comprises a pin body, a tail chamfer and a head arc, wherein the tail chamfer and the head arc are fixedly arranged at two ends of the pin body respectively.
Preferably, the U-shaped notch is matched with the left end of the screw and the anti-loosening pin.
(III) advantageous effects
The invention has the beneficial effects that:
1. this special tamper-proof structure adopts the protruding design of side annular through rejecting traditional design theory, has avoided the overlapping risk with other patents, for the screw afterbody terminal surface processing that traditional tamper-proof structure adopted, positive design thinking, this design more possesses the novelty.
2. This special tamper-proof structure, through the side annular design that sets up, the disguise is stronger when the assembly, can avoid being cracked or carrying out artificial adjustment, can avoid the carburetor to damage or lose, and the security of product is better.
3. This special tamper-proof structure, simple structure, processing is convenient, can realize mass production, is convenient for promote this tamper-proof structure.
