DETAILED DESCRIPTION

[0025] In order to make the utility model purposes, technical scheme carry out clearly, completely describe, and the advantage is more clear and clear, following combining the drawing to the utility model embodiment further detailed explanation.Should understand, the specific embodiment described here is the utility model a part of embodiment, instead of all the embodiment, just to explain the utility model embodiment, and not for the limitation of the utility model embodiment, the ordinary skill in the art person who obtains all other embodiments without doing the creative labor is within the scope of the utility model protection.

[0026] Please refer to Figures 1-10 The utility model provides a kind of technical scheme: a double opening spanner with lubricating function, including double opening spanner body 1, the surface of double opening spanner body 1 is equipped with reserved port 2, both ends of reserved port 2 are equipped with installation groove 3, oil absorbing cotton block 6 is inserted in the inside of installation groove 3, oil absorbing cotton block 6 is inserted in installation groove 3 after being soaked by lubricating oil, both ends of double opening spanner body 1 are equipped with oil infiltration groove 4, oil infiltration groove 4 is equipped with oil infiltration hole 5 on surface, oil infiltration hole 5 is connected with installation groove 3, piston plate 7 is slidably connected in the inside of installation groove 3, one end of piston plate 7 is fixed with push rod 8.When the opening of handle needs to be lubricated, push rod 8 is pushed, push rod 8 pushes piston plate 7, piston plate 7 extrudes oil absorbing cotton block 6, and the lubricating oil absorbed by oil absorbing cotton block 6 is extruded, and the force of pushing push rod 8 and the distance of pushing push rod 8 are controlled according to needs, and the extruded lubricating oil is infiltrated to oil infiltration groove 4 through oil infiltration hole 5, that is, lubricating oil is delivered to the opening of double opening spanner body 1;Reserved port 2 is equipped with oil absorbing cotton block 6 and push rod 8 on both sides, and the lubrication of two openings of double opening spanner body 1 is satisfied.

[0027] The inside of the oil infiltration groove 4 is fixed with an oil application cotton strip 12, which protrudes from the oil infiltration groove 4. A sealing ring 9 is sleeved on the rod body of the push rod 8 and is fixed in the slot opening of the installation slot 3. The end of the push rod 8 away from the piston plate 7 is fixed with a push block 10, which is slidingly connected in the reserved port 2. The height of the push block 10 is less than that of the reserved port 2. The surface of the push block 10 is fixed with rubber supporting blocks 11, one end of which is fixed to the surface of the reserved port 2. The two rubber supporting blocks 11 are symmetrically distributed about the push rod 8. The rubber supporting blocks 11 initially support the push block 10, and at this time the piston plate 7 does not extrude the oil absorbing cotton block 6.

[0028] An oil injection hole 13 is formed on the surface of the double-opening wrench body 1, which is in communication with the installation slot 3. A rubber sealing block 14 is fixed in the oil injection hole 13. When it is necessary to supplement lubricating oil to the oil absorbing cotton block 6, the lubricating oil is sucked by a needle tube, the needle is inserted through the rubber sealing block 14, and then injected into the installation slot 3. The lubricating oil is absorbed by the oil absorbing cotton block 6, and the needle is separated from the rubber sealing block 14.

[0029] The use process of the double-opening wrench with lubricating function is as follows:

[0030] Ensure that the surface of the double-opening wrench body 1 is clean and free of impurities. Observe and confirm that the oil infiltration groove 4, the oil infiltration hole 5, the installation slot 3, and the reserved port 2 are intact. Take out the oil absorbing cotton block 6 soaked in the appropriate amount of lubricating oil. Insert the oil absorbing cotton block 6 into the installation slot 3 at both ends of the double-opening wrench body 1, ensuring that the oil absorbing cotton block 6 completely fits the slot wall. Confirm that the rubber supporting blocks 11 are in the initial state of supporting the push block 10, at which time the piston plate 7 does not extrude the oil absorbing cotton block 6. Check whether the sealing ring 9 is firmly fixed in the slot opening of the installation slot 3 to prevent lubricating oil leakage.

[0031] According to the need, select one or both openings of the double-opening wrench body 1 for lubrication. Gently hold the push block 10 and prepare to push and extrude. Gently push and extrude the push block 10, which drives the push rod 8 to move, and then pushes the piston plate 7 to extrude the oil absorbing cotton block 6. Control the force and distance of pushing and extruding, and adjust the extrusion amount of lubricating oil as needed. The extruded lubricating oil enters the oil infiltration groove 4 through the oil infiltration hole 5. The oil application cotton strip 12 in the oil infiltration groove 4 absorbs and stores part of the lubricating oil, facilitating subsequent application. Observe whether the lubricating oil is evenly distributed at the openings of the double-opening wrench body 1. If lubrication is needed for the other opening, repeat the above steps.

[0032] When it is found that the oil absorbing cotton block 6 needs to be supplemented with lubricating oil, an elongated needle tube is prepared and ensured to be clean and free of impurities. The needle tube needle head is gently penetrated through the rubber sealing block 14, and attention is paid to avoid damaging the integrity of the rubber sealing block. An appropriate amount of lubricating oil is slowly injected into the mounting groove 3 through the needle tube, and it is ensured that the lubricating oil is fully absorbed by the oil absorbing cotton block 6. After completing the oil injection, the needle head is gently pulled out of the rubber sealing block 14, and it is checked whether there is lubricating oil leakage.

[0033] Although the embodiments of the present application have been shown and described, it is to be understood that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present application, and the scope of the present application is defined by the appended claims and their equivalents.
