Technical Field
[0001] This utility model relates to the field of shaft and key pullers, specifically a quick shaft and key puller. Background Technology
[0002] The keyboard is the primary method used in office systems. It can be used to input both text and data. The keyboard contains alphanumeric keys like those on a regular English typewriter, as well as some special keys. Users input programs, commands, and data into the computer by pressing these keys. It is an important tool for human control of the computer. The keyboard "switches" are also called keyboard switches. Over time, keyboard switches are prone to damage, which can lead to poor contact of the keys. Therefore, it is necessary to replace the keyboard switches. Users can use a keycap puller to replace damaged keyboard switches.
[0003] Existing keycap pullers are usually composed of simple metal claws. When disassembling a keyboard switch, the metal claws are squeezed to lock onto the outer wall of the switch. The diameter of the metal claws is only slightly larger than the keyboard switch, which means that after removing the switch, the metal claws must be released and the switch shaken to fall off. This method is quite cumbersome. Utility Model Content
[0004] Therefore, the purpose of this utility model is to provide a quick key and shaft puller to solve the technical problems mentioned in the background section.

The bottom of the housing 1 has a limiting groove 7, the inner wall of the limiting groove 7 is in contact with the outer wall of the metal claw rod 6, the top of the movable block 16 is fixed with two sets of elastic rods 18, the first spring 20 is fixed between the two sets of elastic rods 18, the top of the movable block 16 is fixed with a connecting post 17, the inside of the housing 1 is movably installed with a push shaft 3, and the bottom of the push shaft 3 is fixed with a contact rod 22, the bottom of the push shaft 3 is fixed with a second spring 21, and the end of the second spring 21 is connected to the connecting post 17. The bottom of the housing 1 has multiple sets of limiting grooves 7, and the inner wall of the limiting groove 7 is in contact with the outer wall of the metal claw rod 6.
[0032] For details regarding the above embodiments, please refer to 2 and 3. Figure 3 Both the housing 1 and the side cover 2 have a movably installed locking block 8 on one side, and a buckle 9 is fixed on one side of the locking block 8. The outer walls of the housing 1 and the side cover 2 are provided with locking positions that match the buckle 9. The locking block 8 can limit the metal sleeve 4 and prevent the metal sleeve 4 from detaching from the housing 1 and the side cover 2.
[0033] For details regarding the above embodiments, please refer to [link / reference]. Figure 3 Both the outer walls of the housing 1 and the side cover 2 are provided with slots 11. The end of the metal sleeve 4 is located on the inner wall of the slot 11. The slot 11 provides a convenient way to install the metal sleeve 4. The end of the metal sleeve 4 is inserted into the slot 11, allowing the end of the metal sleeve to rotate within the slot.
[0034] For details regarding the above embodiments, please refer to [link / reference]. Figure 2 and Figure 4 The inner wall of the housing 1 is fixed with a limiting post 12, and the inside of the shaft 3 is provided with a limiting hole 31. The limiting post 12 is set inside the limiting hole 31. By the cooperation between the limiting post 12 and the limiting hole 31, the movement of the shaft 3 can be limited, so that the shaft 3 can only move in a fixed direction and distance, and avoid the shaft 3 from moving too far.
[0035] For details regarding the above embodiments, please refer to [link / reference]. Figure 2 A pressing block 32 is fixed to the end of the pressing shaft 3, and the diameter of the pressing block 32 is larger than that of the pressing shaft 3, which makes it convenient to press the pressing shaft 3.
[0036] For details regarding the above embodiments, please refer to [link / reference]. Figure 2 and Figure 4 A stop block 14 is fixed at the bottom of the push shaft 3, and a limiting part 13 is provided on the inner wall of the housing 1. The limiting part 13 can limit the push shaft 3 so that the push shaft 3 can only move within a specified range.
[0037] For details regarding the above embodiments, please refer to [link / reference]. Figure 2 and Figure 4 The inner wall of the housing 1 is fixed with a protrusion 15, and the outer wall of the elastic rod 18 is fixed with a triangular block 19. The protrusion 15 can limit the triangular block 19, so that the elastic rod 18 will not easily shake and the gripping of the keyboard switch is more stable.
[0038] For details regarding the above embodiments, please refer to [link / reference]. Figure 2 The end of the elastic rod 18 is provided with a bevel, and the bottom of the contact rod 22 is provided with a bevel. The beveled contact rod 22 and the elastic rod 18 can reduce the friction between the contact rod 22 and the elastic rod 18 when the contact rod 22 moves downward.
[0039] In practical operation, when the present invention is used to remove the keycaps on a computer keyboard, the two sets of metal sleeves on the outer wall of the housing are rotated 180 degrees, and the metal sleeves 4 are disengaged from the inside of the storage groove. Then, the two sets of metal sleeves 4 are put on the outer wall of the keycaps, and the keycaps on the computer keyboard can be removed by holding the housing 1 and pulling it upward. Then, the metal sleeves 4 are rotated 180 degrees to reset, so that the metal sleeves are stored in the inside of the storage groove 5.
[0040] When the keyboard switch needs to be disassembled, the slot 10 at the bottom of the housing 1 is inserted into the outside of the keyboard switch, and the metal claw 6 is sleeved on the outer wall of the keyboard switch. Then, the housing 1 is pushed down. When the housing 1 is pushed down, the keyboard switch touches the movable block 16, causing the movable block 16 to slide upward inside the housing 1. At the same time, the metal claw 6 is squeezed and retracted by the limiting groove 7. The hook of the metal claw 6 is engaged with the outer wall of the keyboard switch. When the movable block 16 moves upward, it will drive the elastic rod 18 to move upward. The triangular locking block 19 on the outer wall of the elastic rod 18 contacts the protrusion 15 on the inner wall of the housing 1, which will cause the two sets of elastic rods 18 to come closer. When the two sets of elastic rods 18 come closer, they will squeeze the first spring 20. When the triangular locking block 19 is above the protrusion 15, the first spring 20 drives the elastic rod 18 to reset. The triangular locking block 19 is engaged above the protrusion 15. At this time, the keyboard switch is pulled out.
[0041] When it is necessary to release the keyboard switch gripped at the bottom of the housing, press down on the pressing block 32. The pressing block 32 drives the pressing shaft 3 to slide inside the housing 1. Then, the contact rod 22 at the bottom of the pressing shaft 3 contacts the top of the elastic rod 18, which squeezes the elastic rod 18 closer together. Then, the triangular locking block 19 disengages from the protrusion 15. Under the release of the elastic force of the second spring 21, the connecting post 17 drives the movable block 16 to slide down inside the housing. The end of the metal claw rod 6 extends out of the outer wall of the housing slot 10. At this time, the hook of the claw disengages from the outer wall of the keyboard switch, so that the keyboard switch is released.
