[0021] In the description of this invention, unless otherwise explicitly defined, terms such as "setup" and "connection" should be interpreted broadly, and those skilled in the art can reasonably determine the specific meaning of the above terms in this invention in conjunction with the specific content of the technical solution.

[0022] According to an embodiment of the present invention, a fiber clamp includes: a fixing assembly 100, including a fixing unit 110 and a first guide post 120, wherein the fixing unit 110 is provided with a pin groove 111 and the fixing unit 110 is connected to the first guide post 120; and a movable assembly 200, including a movable unit 210, a pin 220, a loosening block 230, a first cylindrical block 240, and an elastic unit 250; the movable unit 210 is provided with a first limiting groove 2121, a second limiting groove 2122, a first inclined groove 2123, and a first track 2111, wherein the second limiting groove 2122 penetrates the surface of the movable unit 210, the top of the first inclined groove 2123 communicates with the first limiting groove 2121, the bottom of the first inclined groove 2123 communicates with the second limiting groove 2122, and the lower side of the first inclined groove 2123 communicates with the first track 2111. The upper part of 3 is inclined away from the first track 2111; the ejector pin 220 is connected to the movable unit 210, the ejector pin 220 is connected to the ejector pin groove 111, the first guide post 120 is slidably connected to the first track 2111, the first cylindrical block 240 is slidably connected to the first inclined groove 2123, the elastic unit 250 is located in the first limiting groove 2121, the loosening block 230 is located in the second limiting groove 2122, the first cylindrical block 240 abuts against the lower end of the elastic unit 250 and the upper end of the loosening block 230 respectively; the elastic unit 250 drives the first cylindrical block 240 to slide down the first inclined groove 2123 so that the first cylindrical block 240 is wedge-tightly connected to the first guide post 120; the loosening block 230 drives the first cylindrical block 240 to slide up the first inclined groove 2123 so that the first cylindrical block 240 is unlocked from the first guide post 120.

[0023] For example, such as Figure 1-5 As shown, the movable component 200 has two states: a self-locking state and an unlocked state. When it is necessary to clamp the fiber bundle sample, the fiber bundle sample is first folded and placed into the ejector pin groove 111 to ensure that the sample can be stably supported. Then, the movable component 200 is in the unlocked state, and then the movable component 200 slides along the first guide post 120 and approaches the fixing unit 110 to cause the ejector pin 220 to be inserted into the ejector pin groove 111. The end of the ejector pin 220 gradually abuts against and presses the sample placed in the ejector pin groove 111, so that it is firmly attached to the bottom of the groove. Finally, the movable component 200 is in the self-locking state, thereby fixing the position of the ejector pin 220 in the ejector pin groove 111 and realizing the fixation of the fiber bundle sample.

[0024] Specifically, the unlocking process is as follows: the user or other tool applies a pushing force to the release block 230 through the second limiting groove 2122, causing the release block 230 to move upward from below the first inclined groove 2123. This causes the release block 230 to drive the first cylindrical block 240 to slide upward from the first inclined groove 2123, and the first cylindrical block 240 compresses the elastic unit 250, driving the elastic unit 250 to move towards the top surface of the first limiting groove 2121, thereby causing the first cylindrical block 240 to gradually move away from the first limiting groove 2121. When the elastic unit 250 moves to the top surface of the first limiting groove 2121, it causes the first cylindrical block 240 to stop sliding. At this time, the first cylindrical block 240 is located above the first inclined groove 2123 and no longer contacts the first guide post 120. As a result, the first guide post 120 is no longer wedged by the first cylindrical block 240, so the movable component 200 is in the unlocked state, which allows the movable unit 210 to move freely on the first guide post 120.

[0025] The self-locking process is as follows: the user or other tools remove the pushing force on the release block 230, causing the elastic unit 250 to drive the first cylindrical block 240 to slide down the first inclined groove 2123 under its own elastic force. The first cylindrical block 240 drives the release block 230 to move towards the bottom surface of the second limiting groove 2122, thereby causing the first cylindrical block 240 to gradually approach the first guide post 120. When the release block 230 moves to abut the bottom surface of the second limiting groove 2122, the release block 230 causes the first cylindrical block 240 to stop sliding. At this time, the first cylindrical block 240 is located below the first inclined groove 2123, and the first cylindrical block 240 and the side of the first guide post 120 are closely attached and generate a wedge-tightening effect. The wedge-tightening force between the two is converted into static friction force on the first guide post 120, thereby preventing the movable component 200 from moving on the first guide post 120, and thus causing the movable component 200 to be in a self-locking state, locking the position of the movable unit 210.

[0026] Therefore, under the combined action of the loosening block 230, the first cylindrical block 240, and the elastic unit 250, the movable component 200 and the first guide post 120 can be self-locked or unlocked, thereby facilitating the movement of the ejector pin 220 by the movable component 200, thus improving the movement efficiency of the ejector pin 220. At the same time, the ejector pin 220 can be stably fixed in the ejector pin groove 111, so that the fiber bundle sample is uniformly subjected to the clamping force of the ejector pin 220, thereby achieving stable clamping of the fiber bundle sample, preventing the fiber bundle sample from deforming or slipping, and thus improving the slice quality and accuracy.

[0027] In some specific embodiments of the present invention, the movable unit 210 includes a movable outer shell 211 and a fixing block 212. The movable outer shell 211 is provided with a cavity 2112. The fixing block 212 is connected to the movable outer shell 211, so that a first limiting groove 2121 is formed between the upper part of the fixing block 212 and the cavity 2112, a second limiting groove 2122 is formed between the lower part of the fixing block 212 and the cavity 2112, and a first inclined groove 2123 is formed between the side of the fixing block 212 and the cavity 2112.

[0028] For example, such as Figure 3-4 As shown, the fixing block 212 is used to divide the cavity 2112 into two parts: the first limiting groove 2121 and the second limiting groove 2122, so that the loosening block 230 and the elastic unit 250 are located above and below the fixing block 212 respectively, effectively limiting the movement range of the loosening block 230 and the elastic unit 250, thereby ensuring that the first cylindrical block 240 slides stably on the first inclined groove 2123.

[0029] Specifically, when the movable unit 210 is in the unlocked state, the top of the loosening block 230 abuts against the bottom of the fixing block 212, and the top of the elastic unit 250 abuts against the top surface of the first limiting groove 2121. At this time, the first cylindrical block 240 is located above the first inclined groove 2123, and the first cylindrical block 240 does not wedge against the first guide post 120. When the movable unit 210 is in the self-locking state, the bottom of the loosening block 230 abuts against the bottom of the second limiting groove 2122, and the bottom of the elastic unit 250 abuts against the top of the fixing block 212. At this time, the first cylindrical block 240 is located below the first inclined groove 2123, and the first cylindrical block 240 wedges against the first guide post 120. It can be seen that under the action of the first limiting groove 2121 and the second limiting groove 2122, the first cylindrical block 240 can slide only within the range of the first inclined groove 2123, thereby providing a power basis for the self-locking or unlocking of the movable component 200.

[0030] In some specific embodiments of the present invention, the elastic unit 250 includes a spring 251 and a movable block 252. The upper end of the spring 251 is connected to the movable unit 210, the lower end of the spring 251 is connected to the upper end of the movable block 252, the lower end of the movable block 252 abuts against the first cylindrical block 240, and the movable block 252 is slidably connected to the first limiting groove 2121.

[0031] For example, such as Figure 1As shown, when the movable block 252 moves upward to the first limiting groove 2121, the deformation of the spring 251 increases, giving it a stronger elastic force. When the thrust on the loosening block 230 is removed, the movable block 252 is only subjected to the elastic force of the spring 251. Therefore, under the action of the elastic force of the spring 251, the movable block 252, the first cylindrical block 240 and the loosening block 230 are driven to reset, thereby causing the first cylindrical block 240 to re-wedge with the first guide post 120, realizing the self-locking of the movable unit 210.

[0032] In some specific embodiments of the present invention, the movable block 252 is provided with a first protrusion 2521, the first protrusion 2521 is slidably connected to the first inclined groove 2123, and the first protrusion 2521 abuts against the first cylindrical block 240.

[0033] For example, such as Figure 6 As shown, by providing a first protrusion 2521 on the movable block 252, it is convenient for the first protrusion 2521 to contact the first cylindrical block 240. Moreover, under the driving force of the first cylindrical block 240 or the spring 251, the first protrusion 2521 can slide along the first inclined groove 2123, thereby improving the movement stability and accuracy of the movable block 252.

[0034] In some specific embodiments of the present invention, the upper end of the movable block 252 is provided with a mounting position 2522, and the lower end of the spring 251 is connected to the mounting position 2522.

[0035] For example, such as Figure 6 As shown, by setting the mounting position 2522, the connection between the movable block 252 and the spring 251 can be made more stable, and a certain basis can be provided for the deformation direction of the spring 251, preventing the spring 251 from bending to the side.

[0036] In some specific embodiments of the present invention, a second protrusion 231 is provided on the loosening block 230, the second protrusion 231 is slidably connected to the first inclined groove 2123, and the second protrusion 231 abuts against the first cylindrical block 240.

[0037] For example, such as Figure 8 As shown, by providing a second protrusion 231 on the loosening block 230, it is convenient for the second protrusion 231 to contact the first cylindrical block 240. Moreover, under external thrust or driving force of the first cylindrical block 240, the second protrusion 231 can slide along the first inclined groove 2123, thereby improving the movement stability and accuracy of the loosening block 230.

[0038] In some specific embodiments of the present invention, the surface of the loosening block 230 is recessed to form a handle 232.

[0039] For example, such as Figure 8As shown, the handle 232 is designed to facilitate the application of external force to the release block 230, thereby improving the moving efficiency of the release block 230.

[0040] In some specific embodiments of the present invention, the movable component 200 further includes a guide rod 260, an elastic unit 250 is provided with a first through hole 2524, a fixing block 212 is provided with a second through hole 2125, and a loosening block 230 is provided with a third through hole 234. The elastic unit 250 is slidably connected to the guide rod 260 through the first through hole 2524, and the loosening block 230 is slidably connected to the guide rod 260 through the third through hole 234. The guide rod 260 is connected to the second through hole 2125, the first limiting groove 2121, and the second limiting groove 2122, respectively.

[0041] For example, such as Figure 1 , Figure 6-8 As shown, the upper end of the guide rod 260 is fixed to the top of the first limiting groove 2121, the lower end of the guide rod 260 is fixed to the bottom of the second limiting groove 2122, and the middle part of the guide rod 260 is fixed in the second through hole 2125 of the fixing block 212. Since both the elastic unit 250 and the loosening block 230 can slide along the guide rod 260, it provides guidance for their sliding direction, preventing them from shifting their position during sliding, thereby improving the efficiency of the elastic unit 250 and the loosening block 230 in driving the first cylindrical block 240 to move. The number of guide rods 260 can be set to two, and the number of the first through hole 2524, the second through hole 2125, and the third through hole 234 can also be set to two respectively. In some specific embodiments of the present invention, the fixing component 100 further includes a second guide post 130, and the movable unit 210 further includes a second cylindrical block 270. The movable unit 210 is provided with a second inclined groove 2124 and a second track 2113. The top of the second inclined groove 2124 communicates with the first limiting groove 2121, the bottom of the second inclined groove 2124 communicates with the second limiting groove 2122, the lower part of the second inclined groove 2124 communicates with the second track 2113, and the upper part of the second inclined groove 2124 is inclined away from the second track 2113. The column 130 is slidably connected to the second track 2113, and the second cylindrical block 270 is slidably connected to the second inclined groove 2124. The second cylindrical block 270 abuts against the lower end of the elastic unit 250 and the upper end of the loosening clamp block 230 respectively. The elastic unit 250 drives the second cylindrical block 270 to slide down the second inclined groove 2124 so that the second cylindrical block 270 is wedge-tightly connected to the second guide column 130. The loosening clamp block 230 drives the second cylindrical block 270 to slide up the second inclined groove 2124 so that the second cylindrical block 270 is unlocked from the second guide column 130.

[0042] For example, such as Figure 1As shown, to make the movement of the movable unit 210 more stable, a second guide post 130 is provided, allowing the movable unit 210 to move simultaneously along the first guide post 120 and the second guide post 130, thereby improving the accuracy of the movement of the movable unit 210. Simultaneously, by creating a wedging effect between the first cylindrical block 240 and the first guide post 120, and between the second cylindrical block 270 and the second guide post 130, the movable unit 210 is subjected to two wedging forces simultaneously, thereby strengthening the self-locking force of the movable unit 210, making the movable unit 210 more stable, and further improving the stability of the ejector pin 220 within the ejector pin groove 111, achieving stronger fixation of the fiber bundle sample.

[0043] Specifically, during the unlocking process of the active unit 210, the movement of the second cylindrical block 270 is as follows: An external force is applied to the loosening block 230 through the second limiting groove 2122, causing the loosening block 230 to move upwards from below the second inclined groove 2124. This causes the loosening block 230 to drive the second cylindrical block 270 to slide upwards towards the second inclined groove 2124. The second cylindrical block 270 compresses the elastic unit 250 and drives the elastic unit 250 to move towards the top surface of the second limiting groove 2122, causing the second cylindrical block 270 to gradually move away from the second guide post 130. When the elastic unit 250 moves to abut against the top surface of the second limiting groove 2122, the elastic unit 250 causes the second cylindrical block 270 to stop sliding. At this point, the second cylindrical block 270 is located above the second inclined groove 2124 and no longer contacts the second guide post 130, thus freeing the second guide post 130 from the wedging effect of the second cylindrical block 270.

[0044] During the self-locking process of the active unit 210, the movement of the second cylindrical block 270 is as follows: when the external force on the release block 230 is removed, the elastic unit 250 drives the second cylindrical block 270 to slide down the second inclined groove 2124 under its own elastic force, and the second cylindrical block 270 drives the release block 230 to move towards the bottom surface of the second limiting groove 2122, thereby making the second cylindrical block 270 gradually approach the second guide post 130; when the release block 230 moves to abut the bottom surface of the second limiting groove 2122, the release block 230 causes the second cylindrical block 270 to stop sliding. At this time, the second cylindrical block 270 is located below the second inclined groove 2124, and the second cylindrical block 270 is in close contact with the side of the second guide post 130 and produces a wedge-tightening effect.

[0045] In some specific embodiments of the present invention, a guide surface 1111 is provided on the upper part of the ejector groove 111.

[0046] For example, such as Figure 5As shown, the guide surface 1111 enlarges the entrance of the ejector groove 111, thereby facilitating the insertion of the fiber bundle sample into the ejector groove 111 along the guide surface 1111.

[0047] Other configurations and operations of a fiber clamp according to an embodiment of the present invention are known to those skilled in the art and will not be described in detail here.

[0048] The following is for reference. Figure 1-8 As shown, a fiber holder according to an embodiment of the present invention is described in detail with reference to a specific example. It is worth understanding that the following description is merely illustrative and not a specific limitation of the invention.

[0049] A fiber clamp includes a fixing component 100 and a movable component 200. The fixing component 100 includes a fixing unit 110, a first guide post 120, and a second guide post 130. The fixing unit 110 is provided with a pin groove 111 and is connected to the first guide post 120 and the second guide post 130 respectively. The movable component 200 includes a movable housing 211, a fixing block 212, a pin 220, a loosening block 230, a first cylindrical block 240, a second cylindrical block 270, a spring 251, a movable block 252, and a guide rod 260.

[0052] The second limiting groove 2122 penetrates the surface of the movable unit 210. The surface of the loosening block 230 is recessed to form a handle 232. The movable block 252 is provided with a first through hole 2524. The fixed block 212 is provided with a second through hole 2125. The loosening block 230 is provided with a third through hole 234.

The guide rod 260 is connected to the second through hole 2125, the first limiting groove 2121, and the second limiting groove 2122 respectively.

[0053] According to an embodiment of the present invention, a fiber clamp can achieve at least the following effects by being configured such that the movable outer shell 211 has two states: a self-locking state and an unlocked state. When it is necessary to clamp a fiber bundle sample, the fiber bundle sample is first folded and placed into the pin groove 111 to ensure that the sample can be stably supported. Then, the movable outer shell 211 is in the unlocked state, and then the movable outer shell 211 is slid along the first guide post 120 and the second guide post 130 and close to the fixing unit 110 to cause the pin 220 to be inserted into the pin groove 111. The end of the pin 220 gradually abuts against and presses the sample placed in the pin groove 111, so that it is firmly attached to the bottom of the groove. Finally, the movable outer shell 211 is in the self-locking state, thereby fixing the position of the pin 220 in the pin groove 111 and realizing the fixation of the fiber bundle sample.

[0054] Specifically, the unlocking process is as follows: the user or other tools apply a pushing force through the handle 232 of the release block 230, causing the release block 230 to move upward along the guide rod 260, thereby causing the second protrusion 231 to drive the first cylindrical block 240 to slide upward above the first inclined groove 2123, and the fourth protrusion 233 to drive the second cylindrical block 270 to slide upward above the second inclined groove 2124. At the same time, the first cylindrical block 240 and the second cylindrical block 270 drive the movable block 252 to move upward along the guide rod 260 through the abutting action of the first protrusion 2521 and the third protrusion 2523, respectively, thereby causing the movable block 252 to continuously compress the spring 251. When the movable block 252 moves to the top surface of the first limiting groove 2121, the first cylindrical block 240 and the second cylindrical block 270 stop sliding. At this time, the first cylindrical block 240 is located above the first inclined groove 2123, so the first cylindrical block 240 no longer contacts the first guide post 120, thereby the first guide post 120 is no longer wedged by the first cylindrical block 240; and the second cylindrical block 270 is located above the second inclined groove 2124, and the second cylindrical block 270 no longer contacts the second guide post 130, thereby the second guide post 130 is no longer wedged by the second cylindrical block 270. It can be seen that the movable component 200 is in the unlocked state at this time, allowing it to move freely on the first guide post 120.

[0055] The self-locking process is as follows: When the user or other tools remove the pushing force on the release block 230, the spring 251 drives the movable block 252 to move downward along the guide rod 260 under its own elastic force. This causes the first protrusion 2521 to drive the first cylindrical block 240 to slide down the first inclined groove 2123, and the third protrusion 2523 to drive the second cylindrical block 270 to slide down the second inclined groove 2124. At the same time, the first cylindrical block 240 and the second cylindrical block 270 drive the release block 230 to move downward along the guide rod 260 through the abutting action of the second protrusion 231 and the fourth protrusion 233, respectively. When the release block 230 moves to the bottom surface of the second limiting groove 2122, the first cylindrical block 240 and the second cylindrical block 270 stop sliding. At this time, the first cylindrical block 240 is located below the first inclined groove 2123, and the first cylindrical block 240 is in close contact with the side of the first guide post 120, creating a wedge-tightening effect. The second cylindrical block 270 is located below the second inclined groove 2124, and the second cylindrical block 270 is in close contact with the side of the second guide post 130, creating a wedge-tightening effect. It can be seen that under the wedge-tightening force between the first cylindrical block 240 and the first guide post 120, and between the second cylindrical block 270 and the second guide post 130, a certain static friction force can be generated between them, thereby preventing the movable outer shell 211 from moving on the first guide post 120 and the second guide post 130, thus putting the movable outer shell 211 in a self-locking state and locking the position of the movable outer shell 211.

[0056] Therefore, under the combined action of the loosening block 230, the fixing block 212, the spring 251, the movable block 252, the first cylindrical block 240, the second cylindrical block 270, and the guide rod 260, the movable outer shell 211 can achieve self-locking or unlocking with the first guide post 120 and the second guide post 130, thereby facilitating the movement of the ejector pin 220 by the movable outer shell 211, thus improving the movement efficiency of the ejector pin 220. At the same time, the ejector pin 220 can be stably fixed in the ejector pin groove 111, so that the fiber bundle sample is uniformly subjected to the clamping force of the ejector pin 220, thereby achieving stable clamping of the fiber bundle sample, preventing deformation or slippage of the fiber bundle sample, and thus improving the slice quality and accuracy.
