A lifting rod is arranged on the outer end of the oil pressing plug column, and the axis of the lifting rod is perpendicular to the axis of the oil pressing plug column. The rocker arm drives the oil pressing plug column to move axially through the lifting rod and simultaneously drives the lifting rod to rotate. The butter gun is improved in structure, which makes the operator more labor-saving during use.

[0004] Under low-temperature working conditions, the viscosity of base oil increases sharply due to low temperature. When the butter gun faces such high-viscosity lubricating grease, the oil injection resistance increases significantly. The hydraulic system needs to output greater pressure to push the lubricating grease to flow, which not only increases the energy consumption of the equipment, but also easily causes the hydraulic components to wear out more severely, shortens the service life of the butter gun, and at the same time, the high-viscosity lubricating grease is difficult to smoothly extrude from the oil outlet, resulting in a significant reduction in oil injection efficiency.

DETAILED DESCRIPTION

[0024] The two embodiments of the application will be described in detail below with reference to the accompanying drawings.

[0025] First embodiment:

[0026] Figures 1-6The utility model discloses a handheld electric butter gun, including electric gun body 1, the inner end sliding connection of electric gun body 1 has and pushes material inner ring block 7, is provided with extrusion spring 6 between electric gun body 1 and pushes material inner ring block 7, is provided with gypsy moth oil storage strip 8 in electric gun body 1, is provided with oil outlet joint 2 in the output end of electric gun body 1, the outer end middle part fixed connection of electric gun body 1 has external annular sheet 3, the lower end fixed connection of external annular sheet 3 has extension hand grip plate 4, the both ends symmetrical fixed connection of extension hand grip plate 4 has the shock pad 5 in, the side fixed connection of electric gun body 1 close to oil outlet joint 2 has electric ring dynamic block 9, the one end fixed connection of electric ring dynamic block 9 close to gypsy moth oil storage strip 8 has double thread sleeve ring layer 10, the output of electric ring dynamic block 9 installs a pair of displacement extension rods 11, is provided with auxiliary assembly 13 on the outside of displacement extension rod 11.

[0027] Figures 1-6 The utility model discloses auxiliary assembly 13 includes two half circle type extrusion contact block 14, gypsy moth oil storage strip 8 is located between oil outlet joint 2 and pushes material inner ring block 7 position, two half circle type extrusion contact block 14 with corresponding displacement extension rod 11 between each other connects, the fixed connection of displacement extension rod 11's outer end has gear outer ring 12, and the meshing connection between gear outer ring 12 and double thread sleeve ring layer 10, the outer end connection of half circle type extrusion contact block 14 has a plurality of electric heating sheet 16, the fixed connection of electric heating sheet 16 away from half circle type extrusion contact block 14's one end has anti -skid line arc outer sheet 17, be provided with hydraulic drive in electric gun body 1, fill with a plurality of oil in gypsy moth oil storage strip 8.

[0028] Figures 1-6When the handheld electric grease gun is started, the hydraulic driver in the electric gun body 1 starts to work to provide a power source for the entire oil injection process. The pressure generated by the hydraulic driver pushes the pushing inner ring block 7 to slide in the electric gun body 1. The spring 6 serves as a buffer and a reset when the pushing inner ring block 7 slides. The sliding of the pushing inner ring block 7 pushes the oil in the caterpillar oil storage strip 8 to move towards the oil outlet connector 2. In the process of pushing the oil, the electric ring moving block 9 is started synchronously. The electric ring moving block 9 generates power through internal circuit electrification to drive the displacement extension rod 11 connected thereto to move. The displacement extension rod 11 drives the auxiliary assembly 13 on the outside to operate. The two half-circle type extrusion contact blocks 14 in the auxiliary assembly 13 move around the caterpillar oil storage strip 8. At the same time, the gear outer ring 12 at the outer end of the displacement extension rod 11 is engaged with the double-threaded sleeve ring layer 10. The threaded structure of the double-threaded sleeve ring layer 10 guides and restricts the movement of the gear outer ring 12, so that the gear outer ring 12 drives the movement track of the displacement extension rod 11 and the half-circle type extrusion contact block 14 to be more stable. The half-circle type extrusion contact block 14 generates extrusion force to cooperate with the electric heating sheet 16 connected to the outer end of the half-circle type extrusion contact block 14 to generate heat through electrification, thereby providing a high-temperature environment for the extrusion process and preventing slipping. The anti-slip arc-shaped outer sheet 17 increases the friction between the half-circle type extrusion contact block 14 and the caterpillar oil storage strip 8 to prevent slipping during the extrusion process. Under the double action of extrusion and heating, the oil close to the position of the oil outlet connector 2 of the caterpillar oil storage strip 8 has its viscosity reduced due to high temperature and its flowability significantly enhanced due to the extrusion force of the half-circle type extrusion contact block 14. This enables the oil to be quickly extruded through the oil outlet connector 2, even in a low-temperature environment, so as to meet the equipment lubrication demand. In the scheme, the electric ring moving block 9 drives the auxiliary assembly 13, the gear outer ring 12 is engaged with the double-threaded sleeve ring layer 10 to guide precise extrusion, the electric heating sheet 16 reduces the viscosity of the oil, the anti-slip arc-shaped outer sheet 17 prevents slipping, the flowability and output efficiency of the oil are strengthened, the vibration and wear of the components are reduced, the stable operation of the equipment is ensured, the service life is prolonged, the maintenance cost is reduced, the lubrication demand of the equipment under different working conditions is effectively met, and the working efficiency, applicability and reliability of the grease gun are significantly improved.

Multiple auxiliary springs 15 are arranged in an arc-shaped equidistant manner. Two semi-circular extrusion contact blocks 14 are symmetrically arranged on both sides of a caterpillar-shaped oil reservoir 8. The auxiliary springs 15 adaptively adjust the extrusion force in real time according to the fit between the semi-circular extrusion contact block 14 and the caterpillar-shaped oil reservoir 8, forming a uniform multi-point pressure distribution, avoiding local pressure imbalance, achieving precise extrusion control of the oil, and ensuring the uniformity and accuracy of the oil injection process.
