Problems solved by technology

[0003] With the upgrade of the National VI regulations, the existing fuel pumps are often fixed in the fuel tank with the Cam-Lock assembly structure. This assembly structure is relatively large, and it is impossible to use fixed-sized tools to directly disassemble the fuel pump through the body inspection port. For installation, the fuel tank must be dismantled first, and then the oil pump must be disassembled. It is very inconvenient to use the existing maintenance tools for operation, which wastes manpower and working hours

Abstract

The utility model relates to a retractable automobile fuel pump disassembly tool, which relates to the field of automobile maintenance. The retractable automotive fuel pump disassembly tool includes a housing, a knob, a plurality of claws, a ratchet crank mechanism and a ratchet locking mechanism. The knob is rotatably connected to the housing, and the plurality of claws are arranged along the circumference of the housing. , and is configured to move toward or away from the housing to clamp or loosen the snap ring of the fuel pump. The ratchet crank mechanism is used to drive each claw to move toward or away from the housing when the knob is rotated. The ratchet is locked The mechanism is used to limit the ratchet crank mechanism to drive the plurality of claws to move toward the housing or release the above limitation. The retractable automotive fuel pump disassembly tool provided by the present application can be snapped or separated from the fuel pump snap ring very conveniently, so that the fuel pump can be disassembled and assembled quickly and efficiently.

Description

technical field [0001] The application relates to the field of automobile maintenance, in particular to a retractable automobile fuel pump disassembly tool. Background technique [0002] The automotive fuel pump is assembled in the fuel tank of the car, and is used to continuously supply the fuel in the fuel tank to the engine, and to feed back the remaining fuel in the tank to the key components of the instrument in real time. When the oil supply of the fuel pump is abnormal or the fuel sensor feedback is abnormal, the fuel pump needs to be inspected, repaired and replaced. [0003] With the upgrade of the National VI regulations, the existing fuel pumps are often fixed in the fuel tank with the Cam-Lock assembly structure. This assembly structure is relatively large, and it is impossible to use fixed-sized tools to directly disassemble the fuel pump through the body inspection port. To assemble, the fuel tank must be removed first, and then the oil pump is disassembled. I...
