A use method of a grease gun with a pump head convenient to disassemble is characterized in that: the method comprises the following specific steps:

the method comprises the following steps: oil absorption, the upper end of the oil storage pipe 41 extends into the butter barrel, the T-shaped threaded rod 48 is drawn downwards to drive the material pushing plate 42 to move synchronously, the material pushing plate 42 moves inwards and sucks butter in the butter barrel into the oil storage pipe 41, the butter entering condition in the oil storage pipe 41 is observed through the observation window 49, when the butter is fully sucked, the locking block 47 can rotate upwards to fix the T-shaped threaded rod 48, and the butter is prevented from being extruded out of the oil storage pipe 41 by the material pushing plate 42 under the action of the elastic force of the third spring 43;

step two: installing, namely, inserting the clamping lugs 37 at two sides of the connecting pipe 26 into the connecting through groove 46, rotating the control handle 24, synchronously rotating the connecting pipe 26 connected with the lower end of the control handle 24 at the moment, rotating the connecting pipe 26 to drive the clamping lugs 37 connected with two ends of the connecting pipe to synchronously rotate, at the moment, under the action of the elastic force of the first spring 35, moving the lock disc 36 downwards and clamping the rubber sealing ring 38 into the rubber clamping groove 45, and simultaneously, because the lock disc 36 is movably connected, moving the connecting pipe 36 upwards and clamping the two groups of clamping lugs 37 into the clamping groove 44 at the moment, and finishing the installation of the oil storage pipe 41;

step three: oiling, the material pushing plate 42 moves upwards under the action of the elastic force of the third spring 43, butter can not move upwards continuously under the blocking of the material blocking rod 31, the T-shaped button 27 is pressed to move inwards along the sliding connection cavity 28, the material blocking rod 31 connected with the rear end of the T-shaped button 27 moves inwards synchronously, butter in the oil storage pipe 41 at the lower end enters the diversion cavity 2 through the through groove 33, when the left end of the material blocking rod 31 moves towards the inside of the sliding groove 30 and touches the induction block 25, the motor 14 rotates and drives the connecting shaft 18 connected with the output end to rotate synchronously, the turntable 17 rotates and drives the connecting bolt 21 connected with the lower end to rotate, the connecting rod 221 sleeved on the connecting bolt 21 drives the material pushing block 22 to move left and right, the material pushing block 22 can block the upper end of the drainage pipe 32 while pushing material, and butter in the diversion cavity 2 is discharged from the gun head 5 under the extrusion of the material pushing block 22, at this point the device may be greased.

Specifically, when the grease gun is used, the upper end of the grease storage tube 41 extends into a grease barrel, the T-shaped threaded rod 48 is drawn downwards to drive the material pushing plate 42 to move synchronously, the material pushing plate 42 moves inwards and sucks grease in the grease barrel into the grease storage tube 41, the condition that the grease in the grease storage tube 41 enters is observed through the observation window 49, when the grease is fully sucked, the locking block 47 can be rotated upwards to fix the T-shaped threaded rod 48, and the grease is prevented from being extruded out of the grease storage tube 41 by the material pushing plate 42 under the action of the elastic force of the third spring 43;

installing an oil storage pipe 41 at the lower end of the control handle 24, specifically, extending the clamping lugs 37 at two sides of the connecting pipe 26 into the connecting through groove 46, rotating the control handle 24, synchronously rotating the connecting pipe 26 connected at the lower end of the control handle 24 at the moment, and driving the clamping lugs 37 connected at two ends of the connecting pipe 26 to synchronously rotate by rotating the connecting pipe 26, wherein at the moment, under the elastic action of the first spring 35, the lock disc 36 moves downwards and clamps the rubber sealing ring 38 into the rubber clamping groove 45, and meanwhile, because the lock disc 36 is movably connected, the connecting pipe 26 moves upwards and clamps the two groups of clamping lugs 37 into the clamping grooves 44 at the moment, and the installation of the oil storage pipe 41 is completed;

the T-shaped threaded rod 48 can move by rotating the locking block 47 downwards, at this time, the material pushing plate 42 moves upwards under the action of the elastic force of the third spring 43, at this time, butter in the oil storage pipe 41 enters the drainage pipe 32 along the connecting pipe 26, the butter cannot move upwards under the blocking of the material blocking rod 31, the T-shaped button 27 is pressed to move inwards along the sliding connection cavity 28, at this time, the material blocking rod 31 connected at the rear end of the T-shaped button 27 moves inwards synchronously, at this time, the butter in the oil storage pipe 41 at the lower end enters the flow guide cavity 2 through the through groove 33, because the sensing block 25 is arranged at the left end of the sliding groove 30, when the left end of the material blocking rod 31 moves towards the sliding groove 30 and touches the sensing block 25, at this time, the motor 14 rotates and drives the connecting shaft 18 connected with the output end of the motor to rotate synchronously, the connecting shaft 18 rotates and drives the rotary disc 17 to rotate, the rotary disc 17 rotates and drives the connecting bolt 21 connected with the lower end of the rotary disc 17 to rotate, the connecting rod 221 sleeved on the connecting bolt 21 drives the material pushing block 22 to move left and right, the material pushing block 22 can push materials and block the upper end of the drainage tube 32 when moving right, grease in the diversion cavity 2 is extruded by the material pushing block 22 and is discharged from the gun head 5, and grease filling can be performed on equipment at the moment.
