[0002] A key puller is a tool used for mechanical keyboards, mainly used to remove and replace keycaps or switches. It is designed to simplify the process and avoid damage to the keyboard.
[0003] The prior art has the following defects: the part of the existing shaft puller used to pull out the keycap is composed of two iron wires. When pulling out the keycap, it is necessary to pry the iron wires apart from both sides, and then pinch the two iron wires with hands to cover the keycap before pulling the keycap upwards. This operation method is relatively cumbersome, which not only increases the operation time, but also may damage the keycap or keyboard due to improper operation for users who are not familiar with the operation. Secondly, the two iron wires used by the shaft puller to pull out the keycap are stored on both sides of the shaft puller, and the width of the iron wires is wider than the shaft puller body. Such a design will affect the grip feel of the shaft puller, making the user feel uncomfortable during use. At the same time, the wider iron wire will also affect the overall aesthetics of the shaft puller and reduce the attractiveness of the product. When carrying and storing the shaft puller, the protruding iron wire may also scratch other objects, causing inconvenience to users. For this reason, a slide rail integrated shaft puller and key puller is proposed to solve the above problems. Utility Model Content

[0031] Next, the technical solutions in the embodiments of the present utility model will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present utility model.
[0032] Refer to Figures 1 - 3 , an embodiment provided by the present utility model: a slide rail integrated shaft and key extractor, including a long frame 1. A key extraction mechanism is provided at the top end of the long frame 1. A positioning block 4 is fixedly connected to the top end of the long frame 1. The positioning block 4 is made of rubber material and has a certain frictional force. A cover plate 12 is fixedly connected to the top end of the long frame 1. The cover plate 12 mainly functions to position the sliding block 2 and the iron wire 3 after they move leftward. An extrusion plate 6 is slidably connected to the inner wall of the long frame 1. The two sides at the right end of the extrusion plate 6 are inclined surfaces, and these inclined surfaces correspond to the inclined surfaces of the elastic plate 7. A pressing block 5 is fixedly connected to the left end of the extrusion plate 6. The pressing block 5 can drive the extrusion plate 6 to move horizontally. An elastic plate 7 is fixedly connected to the inner wall of the long frame 1. When the elastic plate 7 is squeezed, it will bend to a certain extent and return to the state as shown in Figure 5In the initial state, the inner wall of the long frame 1 is penetrated and slidably connected with a connecting head 8. The connecting head 8 mainly serves to connect and support the clamping plate 9. The right end of the connecting head 8 is fixedly connected with the clamping plate 9. The clamping plate 9 is made of an elastic material. When the clamping plate 9 moves to the left, it will be squeezed by the right end side wall of the long frame 1 to cause deformation and move closer to each other. When the clamping plate 9 moves to the right, it will use its own elastic force to reset to the initial state. A connecting component is arranged on the inner wall of the long frame 1.
[0033] Referring to Figures 4 - 6 , the connecting component includes a fixing plate 10. The fixing plate 10 is fixedly connected to the inner wall of the long frame 1. The bottom end of the fixing plate 10 is elastically connected to the pressing plate 6 through a torsion spring 11. The bottom end of the fixing plate 10 is fixedly connected to one end of the torsion spring 11, and the other end of the torsion spring 11 is fixedly connected to the bottom end of the pressing plate 6. When the pressing plate 6 moves to the right, it will compress the torsion spring 11. When resetting, it will use the elastic force of the torsion spring 11 to drive the pressing plate 6 to reset.
[0034] Referring to Figures 1 - 3 , the key-pulling mechanism includes a sliding block 2. The sliding block 2 is made of plastic material and mainly serves to connect the iron wire 3. The sliding block 2 is slidably connected to the top end of the long frame 1. The left end of the sliding block 2 is fixedly connected with the iron wire 3. There are two groups of iron wires 3, which can hook the keycap through the cooperation of the two groups of iron wires 3 and pull out the keycap from the key shaft. The iron wire 3 is penetrated and slidably connected to the inner wall of the long frame 1. A notch corresponding to the iron wire 3 is opened on the long frame 1, which can allow the iron wire 3 to extend out or be received into the notch on the inner wall of the long frame 1. The left end of the sliding block 2 is in contact with the right end of the cover plate 12, and the bottom end of the sliding block 2 is in contact with the top end of the positioning block 4. A groove corresponding to the positioning block 4 is opened at the bottom end of the sliding block 2, which can allow the positioning block 4 to coincide with the groove to position the sliding block 2. The outer wall of the clamping plate 9 is in contact with the inner wall of the long frame 1.
[0035] Referring to Figures 4 - 5 , the right end of the pressing plate 6 is in contact with the left end of the elastic plate 7. The left end of the connecting head 8 is clamped to the inner side wall of the elastic plate 7. The left end of the connecting head 8 is a beveled convex block, the right end of the convex block is a vertical plane, the convex block corresponds to the protruding part on the inner side wall of the elastic plate 7, the right end of the protruding part on the inner side wall of the elastic plate 7 is a bevel, and the left end is a vertical plane. The convex block part of the connecting head 8 is clamped through the vertical plane.
[0036] Working principle: First, when the keycap needs to be disassembled, only need to move the sliding block 2 to the left to expose the iron wire 3 along the notch of the long frame 1 and move the sliding block 2 to the contact position of the cover plate 12. Then, control the entire long frame 1 by hand to make the iron wire 3 stuck between the keycap gaps and pull it out. After the pulling is completed, when the iron wire 3 needs to be stored, the sliding block 2 can be moved to the right to take the iron wire 3 into the iron wire 3. At the same time, the sliding block 2 coincides with the positioning block 4, and the positioning block 4 is used to position the sliding block 2 so that it will not move easily.
[0037] When the key shaft needs to be disassembled, just align the clamping plate 9 with the key shaft. By pressing the entire long frame 1, the clamping plate 9 will drive the connector 8 to move to the right along the inner wall of the long frame 1, and the clamping plate 9 will be stuck in the gap of the key shaft. When the connector 8 moves to the left, the convex inclined surface of the connector 8 will squeeze the convex block inclined surface of the elastic plate 7 to cause the elastic plate 7 to deform. When the vertical plane at the left end of the elastic plate 7 coincides with the convex part of the connector 8, the self-elastic force of the elastic plate 7 will reset, and the vertical plane at the left end of the elastic plate 7 will block the right vertical plane of the convex block of the connector 8, so that the clamping plate 9 is completely stuck into the key shaft. By moving the long frame 1, the clamping plate 9 can be used to pull out the key shaft. When it is necessary to separate the clamping plate 9 from the key shaft, just press the pressing block 5 to drive the pressing plate 6 to move to the right and compress the torsion spring 11 to produce a clear sound for decompression, so that the right inclined surface of the pressing plate 6 squeezes the left inclined surface part of the elastic plate 7, causing the two groups of elastic plates 7 to separate from each other. When the elastic plates 7 separate from each other, the convex part of the elastic plate 7 will be separated from the convex block of the connector 8, and the clamping plate 9 can be slowly reset to the right by its own elastic force and the self-gravity of the connector 8.
[0038] Finally, it should be noted that the above are only the preferred embodiments of the present invention and are not used to limit the present invention. Although the present invention has been described in detail with reference to the foregoing embodiments, for those skilled in the art, they can still modify the technical solutions described in the foregoing embodiments, or perform equivalent replacements for some of the technical features. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principle of the present invention shall be included in the protection scope of the present invention.
