Description

Technical Field

[0001] This utility model relates to the field of key puller technology, and in particular to a four-claw key puller. Background Technology

[0002] Mechanical keyboards are commonly used in office work and competitive gaming. Their use involves handling and cleaning. Each key on a mechanical keyboard is controlled by an individual switch, also known as a "switch." During repair and cleaning, the keycaps and switches need to be removed, requiring a dedicated keycap and switch puller. Existing keycap and switch pullers apply even pressure to all directions of the keycap, ensuring no damage to the keyboard or keycaps during removal. They are easy to use, allow for quick replacement of damaged keycaps without additional tools, and significantly improve repair efficiency.

[0003] In the prior art, the utility model with publication number CN218984670U provides an integrated shaft and key puller, which can realize the functions of pulling shafts and keys. The main shaft retainer is set inside the shaft puller housing, so that the shaft retainer will not be deformed due to movement or storage. At the same time, the externally set key pulling wire can also be folded into the placement groove to effectively play a protective role.

[0004] The aforementioned device uses a double-claw design at the bottom to grip and remove the keyboard switches. However, the double claws can only clamp and fix the switches from two directions during removal, requiring precise alignment for accurate operation. Users often only realize they need to rotate the switches 90° when they can no longer grip them. Furthermore, the internal spring-loaded mechanism may jam due to improper operation, which not only affects the normal use of the device but may also damage it. This application provides a four-claw switch and key puller to address this need. Utility Model Content

[0005] The purpose of this invention is to overcome the shortcomings of the existing technology and provide a four-claw key puller.

[0006] To achieve the above objectives, the present invention adopts the following technical solution: a four-claw key puller, comprising a housing body, the bottom of which forms a cavity, a limiting block is provided in the cavity, a four-claw clamping member is provided at the bottom of the limiting block, the four clamping claws of the four-claw clamping member can move synchronously, and four limiting bottom edges corresponding to the clamping claws are provided at the bottom of the cavity.

[0007] In a preferred embodiment, a support block is provided above the limiting block, a transmission component is provided above the support block, and locking teeth are provided on both sides of the transmission component.

[0008] Furthermore, two rebound plates are provided on the outer side of the transmission component, each rebound plate has an elastic rebound side plate on its top, and each rebound plate has a blocking block inside.

[0009] Furthermore, the end of the elastic rebound side plate abuts against the inner wall of the outer shell body.

[0010] Furthermore, the elastic rebound side plate is set at an acute angle to the rebound plate, and fixed limiting blocks are respectively provided on the front and rear sides of the elastic rebound side plate.

[0011] In a preferred embodiment, the interior of the outer shell body is provided with a first baffle, a second baffle, and a third baffle in sequence from top to bottom.

[0012] In a preferred embodiment, a push button is provided on the top of the outer shell body, a press button is provided on the top of the push button, a guide groove is provided on the push button, and a guide rod is provided inside the outer shell body.

[0013] Furthermore, a barrier plate is provided below the button, and a push plate is provided at the bottom of the barrier plate.

[0014] Furthermore, the four-jaw key puller also includes a spring, the upper end of which is fixed inside the push plate, and the lower end is sleeved above the locking teeth.

[0015] Furthermore, a shell cover plate is provided on the side of the shell body, a fixed cover plate is provided on the shell cover plate, a side cover plate is provided at the bottom of the fixed cover plate, key wires are provided on both sides of the fixed cover plate, and a wire groove is reserved between the shell cover plate and the side cover plate.

[0016] Furthermore, a fixed baffle is provided above the third baffle.

[0017] Furthermore, a fixing baffle is provided above the third baffle. Compared with the prior art, the advantages and positive effects of this utility model are as follows: Compared with the positioning requirements of the two-claw structure, the four-claw keycap puller of this utility model can clamp and fix the keyboard switch from four directions, and there is no need to confirm the direction. The switch can be clamped and fixed in any direction, which can improve the operating efficiency. The keyboard switch is fixed by pressing down with a four-jaw clamp. After the four-jaw clamp is pressed down, the limiting block rises along the inside of the outer shell, causing the support block to slide upward. The support block pushes the transmission component to slide upward, so that the locking teeth engage with the blocking block on the inner wall of the spring plate. The four-jaw clamp retracts inward along the bottom edge of the limiting block, thereby fixing the keyboard switch and making it easy to remove. After the keyboard switch is removed, pressing the press button causes the key to press down along the first baffle, pushing the push plate at the bottom of the baffle plate down towards the spring plate, thereby causing the spring plate to expand outward, causing the locking teeth to disengage from the blocking block. Then, the spring plate rebounds back to its original position through the elastic rebound side plate at the top, causing the keyboard switch to fall off the four-jaw clamp, which solves the problem mentioned in the background art.

[0025] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0026] like Figure 1 - Figure 4 As shown, this embodiment provides a technical solution: a four-claw keycap puller, including a housing body 1, the bottom of the housing body 1 forming a cavity, a limiting block 25 is provided in the cavity, and a four-claw clamping member 3 is provided at the bottom of the limiting block 25. The four clamping claws of the four-claw clamping member 3 move synchronously, and four limiting bottom edges 9 are provided at the bottom of the cavity, each corresponding to one of the four clamping claws. By setting the four-claw clamping member 3, the keyboard switch can be fixed and clamped in four directions. At the same time, the four limiting bottom edges 9 can simultaneously tighten the four-claw clamping member 3, making it more stable when removing the keyboard switch, ensuring the safety and stability of the keyboard switch, and solving the technical problem of the keyboard switch falling off when removing it.

[0027] Going a step further, such as Figure 2 - Figure 4 As shown: A support block 23 is provided above the limiting block 25, and a transmission component 21 is provided above the support block 23. Two spring plates 18 are provided on the outer side of the transmission component 21. Each spring plate 18 has an elastic spring side plate 20 on its top and a blocking block 19 inside each spring plate 18. At the same time, outwardly protruding locking teeth 22 are provided on both sides of the transmission component 21. The locking teeth 22 and the blocking blocks 19 are used to position the transmission component 21 and the spring plates 18. The key puller of this application fixes the keyboard switch with a four-jaw clamp 3. During operation, after pressing down the outer shell body 1, the limiting block 25 slides upward, which causes the support block 23 to slide upward as well. This allows the locking teeth 22 on both sides of the transmission component 21 to tightly engage with the blocking blocks 19 inside the spring plates 18, so that the four-jaw clamp 3 can firmly fix the keyboard switch, which greatly facilitates the subsequent removal operation and ensures the safety and stability of the keyboard switch.

[0028] Furthermore, the outer side of the rebound plate 18 is provided with a barbed elastic rebound side plate 20, which can improve the service life of the rebound plate 18. Figure 2 As shown, each elastic rebound side plate 20 is provided with a fixed limiting block 14 on both the front and rear sides. The fixed limiting block 14 extends from the outer shell body into the interior. It is circular in the figure. In other embodiments, it can be set as a strip, an ellipse, etc. The fixed limiting block 14 is used to prevent the elastic rebound side plate 20 from bending to the side.

[0029] To address the issue of internal component instability during use, in this embodiment, such as... Figure 2 As shown: In this design, a first baffle 10 is provided inside the main body 1 of the outer casing. A second baffle 11 is provided at a certain distance from the first baffle 10, and a third baffle 24 is provided at a certain distance from the second baffle 11. Through the internal design of the main body 1, the first baffle 10 and the outer casing cover 2 can effectively limit the movement of the push button 7, making it more stable when pressed down. At the same time, the second baffle 11 can limit the movement of the barrier plate 17 to prevent it from rising excessively, while the third baffle 24 and the fixed baffle 28 are responsible for limiting the movement of the spring plate 18, so that the spring plate 18 is fixed inside the equipment.

[0030] The four-jaw key puller of this application also includes a spring 15, the upper end of which is fixed inside the push plate 27 and the lower end is sleeved above the locking teeth 22.

[0031] Figure 5 This is an exploded view of the four-jaw key puller of this application.

[0032] Working principle:

[0033] Figure 1 The keycap puller wire 6 is in a folded storage state. When removing the keycap, the keycap puller wire 6 is rotated 180° to enter the working state, as shown below. Figure 2 - Figure 4 As shown. Insert the keycap puller wire 6 into the gaps on both sides of the keyboard key, then use the keycap puller wire 6 to hold the keycap in place, move it upwards to pull out the keycap using the keycap puller wire 6, and then fold it back to store the keycap puller wire 6 into the wire slot 26 between the outer cover plate 2 and the side cover plate 5.

[0034] Next, the keyboard switch is removed: the four-jaw gripper 3 effectively secures the keyboard switch. When the four-jaw gripper 3 is pressed down, the limiting block 25 rises along the inside of the outer casing 1. This action causes the support block 23 to slide upward as well. The upward sliding of the support block 23 further pushes the transmission component 21 upward, thereby causing the locking teeth 22 to engage tightly with the blocking block 19 on the inner wall of the return plate 18. At this time, the four-jaw gripper 3 retracts inward along the bottom edge 9 of the limiting block, further securing the keyboard switch and greatly facilitating the removal operation. After the keyboard switch is removed, pressing the down button 8 causes the key 7 to be pressed down along the guide rod 13 through the guide groove 12. This causes the push plate 27 at the bottom of the barrier plate 17 to exert pressure on the return plate 18. This action causes the return plate 18 to expand outward, and the locking teeth 22 disengage from the blocking block 19. By fixing the cover plate 4 and the guide rod 13, the key 7 is fixed inside the outer shell 1. The limiting member inside the barrier plate 17 can limit the spring 15, so that after pressing down, the spring 15 rebounds upward. At this time, the rebound plate 18 rebounds back to its original position through the elastic rebound side plate 20 at the top, so that the keyboard switch can be smoothly removed from the four-claw clamp 3. This completely solves the technical problem of the keyboard switch falling off when it is removed, and ensures smooth operation and the safety of the keyboard switch.

[0035] The above description is merely a preferred embodiment of the present utility model and is not intended to limit the present utility model in any other way. Any person skilled in the art may make changes or modifications to the above-disclosed technical content to create equivalent embodiments for application in other fields. However, any simple modifications, equivalent changes, and modifications made to the above embodiments based on the technical essence of the present utility model without departing from the technical solution of the present utility model shall still fall within the protection scope of the technical solution of the present utility model.
