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 invention discloses a telescopic disassembling and assembling tool for an automobile fuel pump, and relates to the field of automobile maintenance. The telescopic disassembling and assembling toolfor the automobile fuel pump comprises a shell, a rotary knob, a plurality of clamping jaws, a ratchet crank mechanism and a ratchet locking mechanism, wherein the rotary knob is rotatably connectedto the shell, the multiple clamping jaws are arranged in the circumferential direction of the shell and are configured to move in the direction close to or away from the shell so as to clamp or loosena fuel pump clamping ring, the ratchet crank mechanism is used for driving all the clamping jaws to move in the direction close to or away from the shell when the rotary knob rotates, and the ratchetlocking mechanism is used for limiting the ratchet crank mechanism to drive the multiple clamping jaws to move in the direction close to the shell or releasing the limitation. The telescopic disassembling and assembling tool for the automobile fuel pump can be quite conveniently clamped to or separated from the fuel pump clamping ring, so that the disassembling and assembling operation of the fuel pump is performed 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...
