[0029] The hammer handle 2 is sleeved in the grip 1, and the hammer handle 2 includes a handle body 21 and a docking joint 22. The handle body 21 is connected to the grip 1 at one end away from the docking joint 22. The docking joint 22 is provided with a rotation space 224, and the rotation space 224 is used to place the hammer head 3. An adjusting shaft 4 is provided between the hammer handle 2 and the hammer head 3, so that the hammer head 3 is rotatably connected to the hammer handle 2. The hammer head 3 includes a first hammer head end 31, a second hammer head end 32 and a connecting portion 33. The first hammer head end 31 is connected to a conversion sleeve 5. The utility model changes the angle between the hammer head 3 and the hammer handle 2 through the adjusting shaft 4, so that the repair hammer can repair pits in special positions. The repair hammer is made of nylon, hard rubber and other materials, which can effectively protect the parts to be repaired from additional damage.

[0030] Furthermore, the handle 1 is provided with a plurality of grooves 11 on the outer side wall. The grooves 11 are convenient for human hand holding to prevent the repair hammer from slipping out of the hand and causing damage to the aircraft. A button 12 is provided on one of the side walls of the handle 1; the handle body 21 is provided with a plurality of adjustment holes 211 in the vertical direction at the position corresponding to the button 12. The length of the repair hammer can be adjusted by cooperating with the button 12 and the adjustment hole 211. When the button 12 is pressed, the ejector pin in the button 12 is disengaged from the adjustment hole 211, so that the handle 1 and the hammer handle 2 are in an active state. When the button 12 is released, the ejector pin extends out and is stuck in the adjustment hole 211, fixing the position of the hammer handle 2 so that the length of the repair hammer can be adjusted.

[0031] Furthermore, the butt joint 22 is provided with a rotation space 224 for placing the hammer head 3, and the butt joint 22 is provided with a through hole 221, the through hole 221 is used for the adjustment shaft 4 to pass through, and a limiting groove 222 is provided inside the through hole 221. The limiting groove 222 is used to prevent the adjustment shaft 4 from rotating when the adjustment shaft 4 is pushed, so that the hammer head 3 cannot be stuck. The butt joint 22 is provided with a positioning groove 223 on the side close to the rotation space 224. The hammer head 3 includes: a first hammer head end 31, a second hammer head end 32 and a connecting The connecting portion 33 has a first hammer head end 31 and a second hammer head end 32 at both ends thereof. The first hammer head end 32 is provided with a stepped groove 311, so that the repair hammer can repair parts with a stepped shape. At the same time, the stepped groove 311 can be used to detect some parts that need to be kept vertical. The second hammer head end 32 is connected to the conversion sleeve 5, and the connection method can be a threaded connection or a clamping connection. The conversion sleeve 5 has a striking portion extending outward on the side away from the hammer handle 2. The shape of the striking portion depends on the shape of the part to be repaired.

[0032] Furthermore, the connecting portion 33 is provided with an axial hole 331, which is used for the passage of the adjusting shaft 4 to connect the hammer handle 2 and the hammer head 3. A number of slots 333 are evenly arranged around the axial hole 331, and a positioning protrusion 332 is provided between two adjacent slots 333. The positioning protrusion 332 is adapted to the positioning slot 223; the adjusting shaft 4 is provided with a translation shaft 42, which passes through the through hole 221 and the axial hole 331. Both ends of the translation shaft 42 are provided with a pushing portion 41, and a limit plate 44 is provided at one end close to the translation shaft 42. The position of the limit plate 44 is adapted to the limit slot 222 to prevent rotation when the adjusting shaft 4 is pushed. The adjusting shaft 4 is provided with a block 43 adapted to the slot 333. The length of the block 43 is defined as A, and the length of the adjusting shaft 4 is defined as B, then A<1 / 2B.

[0033] Furthermore, the specific implementation of the present invention is as follows:

[0034] Press the button 12 to adjust the connection position of the hammer handle 2 and the grip 1, and then adjust the length of the repair hammer, which is convenient for the repair hammer to perform repair operations in a narrow space; push the adjusting shaft 4 to disengage the block 43 on the adjusting shaft 4 from the connection with the slot 333, and keep the adjusting shaft 4 moving smoothly through the limit plate 44 to prevent rotation. The rotating hammer head 3 cooperates with the positioning groove 223 and the positioning protrusion 332 to make the hammer head 3 rotate to a specific angle, and temporarily fix the position of the hammer head 3. The positions of the slot 333 and the block 43 after rotation correspond to each other. Then push the adjusting shaft 4 to make the block 43 contact with the slot 333 to fix the position of the hammer head 3; connect the conversion sleeve 5 at the second hammer head end 32, and the conversion sleeve 5 allows the repair hammer to be used on parts with special shapes.
