[0023] A medical device maintenance hammer comprises a first mounting handle 1, a limiting block 2 is fixedly connected to the top of the first mounting handle 1, a hammer head 3 is fixedly connected to the top of the limiting block 2, two nail pulling blocks 4 are fixedly connected to the top of the limiting block 2, and the two nail pulling blocks 4 are symmetrically distributed. A fastening nut 5 is sleeved on the outer surface of the first mounting handle 1, and the fastening nut 5 is movably connected to the limiting block 2. A second mounting handle 6 is sleeved inside the first mounting handle 1, and the fastening nut 5 is sleeved with the second mounting handle 6. An extension component is provided between the first mounting handle 1 and the second mounting handle 6 for the extension connection between the first mounting handle 1 and the second mounting handle 6. The first mounting handle 1 is held by hand and then struck with the hammer head 3. When the nail needs to be pulled out, the nail can be clamped with two nail pulling blocks 4 and then pulled out to complete the nail pulling. When the length of the first mounting handle 1 is sufficient, the fastening nut 5 is rotated to the bottom of the limiting block 2. When the position is adjusted, the fastening nut 5 is rotated between the first mounting handle 1 and the second mounting handle 6 to fasten the first mounting handle 1 and the second mounting handle 6.

[0024] Furthermore, the extension assembly includes a first rack 7, a first mounting groove 9, a first gear 10 and a first fixed plate 13. The interior of the first mounting handle 1 is fixedly connected to two first fixed plates 13, and the two first fixed plates 13 are symmetrically distributed. The outer surfaces of the two first fixed plates 13 that tend to each other are fixedly connected to two first racks 7, and the two first racks 7 are symmetrically distributed. Two first mounting grooves 9 are provided on the outer surfaces of the two first racks 7. The first gears 10 are rotatably connected to the interior of the two first mounting grooves 9, and the second mounting handle 6 drives the second gear 12 in the second mounting groove 11 to rotate during the outward movement.

[0025] Furthermore, two second fixing plates 14 are fixedly connected to the inside of the second mounting handle 6, and the two second fixing plates 14 are symmetrically distributed. Two second racks 8 are fixedly connected to the outer surfaces of the two second fixing plates 14, and the two second racks 8 are symmetrically distributed. Two second mounting grooves 11 are provided on the outer surfaces of the two second fixing plates 14. The insides of the two second mounting grooves 11 are rotatably connected with second gears 12, and the two second gears 12 are meshed with the adjacent first racks 7. The first gear 10 on the first mounting groove 9 moves on the second rack 8, and the first gear 10 on the first mounting groove 9 rotates as the second mounting handle 6 is pulled, and the two first gears 10 move on the second rack 8.
