Environment-friendly gasoline engine particle trap

The invention discloses an environment-friendly gasoline engine particle trap. The environment-friendly gasoline engine particle trap comprises a trap body and exhaust pipes connected to the two ends of the trap body, the exhaust pipes are fixed to limiting moving mechanisms, the limiting moving mechanisms are driven by a bidirectional driving mechanism to move synchronously, the bidirectional driving mechanism comprises a screw rod and a driving part driving the screw to rotate, threaded sections with opposite rotating directions are arranged at the two ends of the screw rod, each limiting moving mechanism comprises a clamping mechanism and a limiting piece which are rotationally matched, and sliding blocks matched with the corresponding threaded sections are arranged on the limiting pieces; and the limiting moving mechanisms are arranged in corresponding guide pipes, guide grooves are formed in the guide pipes, each guide groove comprises a linear section and a spiral section which are connected, guide rods matched with the guide grooves are arranged on the clamping mechanisms, lock catches are arranged on the clamping mechanisms, unlocking pieces used for releasing the clamping mechanisms from clamping the exhaust pipes after the exhaust pipes are connected with the trap body are fixed beside the screw rod, and the unlocking pieces are matched with the lock catches. The trap has the advantages of being reasonable in structure, convenient to position and install and capable of improving installation efficiency.
