Description

Technical Field

[0001] The present invention belongs to the technical field of daily necessities, and in particular relates to an adjustable gear fixing device. Background Art

[0002] The fixing clip is used to clamp the sheets and mattress so that the sheets do not shift and wrinkle, but the commonly used fixing clip is put on the sheets and mattress. For example, the patent number is 2019214292183, and the patent name is an invention patent for a sheet clamping device. Although this patent is applicable to all household users and is easy to use, because it is put on the sheets and mattress, the fixing clip needs to be put on the sheets and mattress from both ends, and then the fixing clip is moved so that the fixing clip moves to the middle and reaches the position where the user wants to clamp, and it also requires a certain amount of force to move it to the position where the clamp is desired, so it cannot be clamped directly from the position where it is desired to be fixed and it is also laborious.

[0003] There is also a utility model patent with patent number 2019205015942, which specifically discloses a quilt holder. However, this patented technology solves the aforementioned issues of labor and fixed position, but the above technical solution only has one clamping gear. If the design is sized for thin items, the upper and lower clamps cannot be locked for thick items; and if the design is sized for thick items, the upper and lower clamps cannot be locked after the upper and lower clamps are locked. Summary of the Invention

[0004] The purpose of the present invention is to provide an adjustable fixing device which is applicable to articles of different thicknesses.

[0005] The object of the present invention is achieved as follows: an adjustable fixing device includes a first clamping plate and a second clamping plate, wherein the second clamping plate is hingedly connected to the first clamping plate and can rotate relative to the first clamping plate; the first clamping plate and the second clamping plate are closed to clamp the article; the fixing device also includes:

[0006] a paddle, rotatably mounted on the first clamping plate; the paddle has an unlocked state and a locked state;

[0007] The pick has:

[0008] The toggle end is used to apply external force to switch the paddle between the unlocked state and the locked state;

[0009] as well as

[0010] The pushing end is at least partially located on the rotation trajectory of the second end of the clamping plate; when the paddle is in the locked state, the pushing end of the paddle and the inner end of the second clamping plate are squeezed in the circumferential direction to maintain the locked state, so that the first clamping plate and the second clamping plate are kept closed;

[0011] The locking state of the toggle end includes at least a first gear position for clamping thick materials and a second gear position for clamping thin materials;

[0012] Furthermore, the pushing end has a first locking position corresponding to the first gear position, and a second locking position corresponding to the second gear position, and the second locking position is closer to the inner end portion than the first locking position.

[0013] Preferably, the first gear position is the position for clamping thick materials, and the second gear position is the position for clamping thin materials;

[0014] Moreover, the paddle is first in the first gear during the rotation process of switching from the unlocked state to the locked state, and enters the second gear under the action of external force depending on whether the pushing end and the inner end are squeezed in the circumferential direction. If there is no squeezing, it enters the second gear.

[0015] Preferably, the pushing end has at least a first limiting portion and a second limiting portion; the second limiting portion is closer to the inner end portion than the first limiting portion;

[0016] When the first limiting portion is in the first gear position at the toggle end, the first limiting portion abuts against the inner end portion to achieve locking; or

[0017] When the dial end is in the second gear position, the second limiting portion abuts against the inner end portion to achieve locking.

[0018] Preferably, the second limiting portion is located on one side of the first limiting portion, so that when the dial end enters the second gear from the first gear, the second limiting portion and the first limiting portion pass through the inner end portion in sequence.

[0019] Preferably, a rotating shaft 1 is provided on both sides of the paddle, and the rotating shaft 1 is located between the paddle end and the push end;

[0020] When the toggle end switches from the first gear to the second gear, the first limiting part and the second limiting part both rotate around the rotating shaft, and the first limiting part switches to the second limiting part to abut against the inner end portion to clamp the thin material.

[0021] Preferably, the first clamping plate has a slot;

[0022] The paddle is provided with a first rotating shaft on both sides, and the paddle slides in the slot via the first rotating shaft to achieve relative sliding with the first clamping plate;

[0023] When the paddle is switched from the first gear position to the second gear position, the paddle is switched from the first travel position to the second travel position by sliding relative to the clamping plate.

[0024] Preferably, the end of the rotating shaft 1 has at least:

[0025] a first protrusion, wherein when the paddle is in the first gear position, the first protrusion corresponds to the first travel position; and

[0026] a second protrusion, wherein when the paddle is in the second gear position, the second protrusion corresponds to the second travel position;

[0027] When the paddle switches from the first gear to the second gear, the end of the rotating shaft 1 switches from the first protrusion abutting against the slot to the second protrusion abutting against the slot; the corresponding pushing end moves from the first stroke position to the second stroke position and then pushes the pushing end of the paddle to move toward the inner end.

[0028] Preferably, the curvature of the second protrusion is greater than the curvature of the first protrusion.

[0029] Preferably, the first protrusion includes a limiting edge, and a limiting recess adapted to the limiting edge is also formed in the slot.

[0030] Preferably, the paddle further has at least one abutting protrusion corresponding to the second stroke position;

[0031] When the paddle rotates from the first gear to the second gear, the abutting protrusion moves from the outside of the first clamping plate to the inside of the first clamping plate and abuts against the inner wall of the first clamping plate, so that the abutting protrusion pushes the pushing end to move toward the inner end.

[0032] Preferably, a cavity is provided on the first clamping plate, and the paddle is rotatably disposed in the cavity;

[0033] The two side walls of the chamber are provided with bosses protruding inwards, and the bosses are used to hinder the rotation of the paddle;

[0034] A supporting portion is provided between the dial end and the rotating shaft 1, and the supporting protrusion is provided on the supporting portion;

[0035] When the paddle is switched from the first gear position to the second gear position, the abutting protrusion moves from the outside of the boss to the lower side of the boss and abuts against the lower side wall of the boss.

[0036] Preferably, the upper end of the abutting protrusion is formed with an arc surface, and the height of the outer side of the arc surface is higher than the height of the inner side of the arc surface.

[0037] Compared with the prior art, the present invention has the following outstanding and beneficial technical effects:

[0038] 1. This invention allows the paddle's toggle end to move from the first to the second position, while the push end moves from the first to the second position. The second position is closer to the inner end than the first position, enabling the second position to clamp thinner objects than the first position. This allows the paddle to switch from clamping thick materials to clamping thin materials. Ultimately, this allows for gear adjustment, resulting in a single fixture suitable for clamping both thin and thick materials.

[0039] 2. At the same time, the present invention can also form a multi-gear design, as long as it corresponds to more positions of the travel position, thereby obtaining a wider and more flexible clamping range.

[0040] 3. The present invention hinges the first and second splints to each other and opens the first and second splints through a paddle, so that the user can clamp and tighten them at any position and the use is very easy and convenient, just by turning the paddle.

[0041] 4. The present invention facilitates the user to toggle the toggle end by means of the space between the connecting groove and the toggle end and / or the recess in the inner wall of the toggle end.

[0042] 5. When the first and second splints are closed and the paddle is locked, the pushing end and the inner end of the second splint are squeezed in the circumferential direction, so there is no need to hook the paddle on the first or second splint, and the first and second splints can be kept closed. This makes the process of clamping objects easier and more labor-saving.

[0043] 6. The design of the avoidance groove of the present invention can provide the inner end with a space for rotation, so that the angle of rotation of the inner end can be adjusted by adjusting the size of the avoidance groove, and finally the angle of opening of the splint 1 and the splint 2 can be adjusted, thereby expanding the thickness range of applicable products of the adjustable fixing device.

DETAILED DESCRIPTION

[0071] The present invention will be further described below with reference to specific embodiments.

[0072] like Figure 1-4 As shown, an adjustable gear fixing device includes a clamping plate 1 and a clamping plate 2, and the clamping plate 1 and the clamping plate 2 are hinged to each other. Therefore, in actual use, the clamping plate 1 and the clamping plate 2 can be opened and closed to each other.

[0073] Combine Figure 2-3 , it can be seen that the rotation connection between the clamping plate 1 and the clamping plate 2 2 is that first, connecting plates 16 are provided on both sides of the clamping plate 1, and a mounting hole 17 is opened at one end of the connecting plate 16. At the same time, a rotating shaft 23 is provided on both sides of the clamping plate 2.

[0074] In actual use, the second clamping plate 2 can be rotatably mounted on the first clamping plate 1 by means of the structure in which the second rotating shaft 23 passes through the mounting hole 17 and rotates in the mounting hole 17 .

[0075] Meanwhile, a chamber 13 is provided on the splint 1 , and a paddle 3 is rotatably provided in the chamber 13 , and two ends of the paddle 3 are respectively a paddle end 31 and a push end 32 .

[0076] Therefore, in actual use, Figure 6As shown, when the paddle 3 is in the locked state, the pushing end 32 of the paddle and the inner end 24 of the second clamp 2 are pressed against each other in the circumferential direction to maintain the locked state, so that the first clamp 1 and the second clamp 2 are kept closed. Therefore, there is no need to lock the first clamp or the second clamp with the paddle to keep the first clamp and the second clamp closed. This makes the clamping process easier and more labor-saving.

[0077] This is because, in the prior art, some technical solutions use a hook at the end of the pick to hook onto the first clamp 1 or the second clamp 2, thereby ultimately achieving the goal of keeping the first clamp 1 and the second clamp 2 closed. However, this solution requires a lot of force to hook the hook at the end, and it also produces noise, making it inconvenient to use.

[0078] At the same time, when opening the splint 1 and the splint 2, the above-mentioned hooks need to be separated from the connection parts. This separation process also requires a relatively large explosive force to be applied, and it will also generate noise.

[0079] In the invention, Figure 2-3 As shown, a connecting groove 11 is provided at the front end of the splint 1, and the toggle end 31 is placed in the connecting groove 11 to limit the toggle end 31 from rotating inward, and the outer end of the toggle end 31 is in the same plane as the outer end of the splint 1, thereby providing the user with a comfortable touch.

[0080] At the same time, in order to facilitate the user to dial the dial end 31 , a space 12 can be optionally provided between the connecting groove 11 and the dial end 31 to facilitate the user to dial the dial end 31 .

[0081] Alternatively, the inner wall of the toggle end 31 is provided with a recess for the user to toggle the toggle end 31 , or a combination of the two.

[0082] Therefore, in this embodiment, the paddle only needs to make the paddle end 31 abut against the connecting groove 11 to keep the first and second splints closed, without the need for a hook structure, so that no noise is generated and the locking and unlocking processes are easier and more labor-saving.

[0083] In order to prevent the paddle 3 from loosening and the splint 1 1 and the splint 2 from suddenly opening, the rear end of the pushing end 32 is pressed against the front side of the upper end of the splint 2, that is, the pushing end 32 and the splint 2 are tightly pressed against each other to form an interference fit, thereby limiting the rotation of the paddle 3 and preventing the splint 1 1 and the splint 2 from suddenly opening.

[0084] That is to say, in this embodiment, a guiding slope 25 is provided on the inner side of the inner end portion 24 , and the guiding slope 25 is interference-fitted with the pushing end 32 , so that the paddle 3 needs to enter or exit the locking state under the action of a certain external force.

[0085] Therefore, in actual use, a certain amount of force is required to rotate the paddle 3, thereby opening the first and second clamping plates 1 and 2. Furthermore, the present invention can also be used to seal snacks from moisture, as well as to clamp other household items, such as tablecloths or curtains. Therefore, the adjustable fixture in this embodiment can clamp thin snack bags, thick tablecloths and curtains, and even the edges of thicker mattresses, achieving clamping capabilities for both thin and thick items.

[0086] like Figure 3 As shown, the guide member 21 is provided with an L-shaped guide groove 22 , and the rear end of the pushing end 32 pushes the second splint 2 to rotate outward along the guide groove 22 , thereby opening the first splint 1 and the second splint 2 .

[0087] The L-shaped guide groove 22 has a larger contact area with the pushing end 32 than the plane, and during the guiding process, the rear end of the pushing end 32 will eventually fall into the notch of the L-shaped guide groove 22, thereby preventing the pushing end 32 from detaching from the guide member 21.

[0088] In addition, in this embodiment, Figure 6 、 8 As shown in Figures 9 and 10, a side of the paddle 3 is formed with an avoidance groove 37, and the outer wall surface of the avoidance groove 37 is at least partially located on the movement trajectory of the inner end portion 24 when the second splint 2 is opened;

[0089] As the opening angle of the first clamping plate 1 and the second clamping plate 2 increases, the inner end portion 24 further extends into the avoidance groove 37 .

[0090] That is to say, when the paddle 3 starts to rotate and is in the unlocked state, the paddle 3 has rotated a certain angle, and the angle of the avoidance groove 37 has changed compared to the locked state. Figure 6 and Figure 8 As shown, it shows that the clamping plate 1 and the clamping plate 2 change from a closed and clamped state to an open state.

[0091] After opening to a certain extent, the inner end portion 24 of the second splint 2 has been located in the avoidance groove 37 after following a set rotation trajectory. In extreme cases, the inner end portion 24 can abut against the outer wall surface of the avoidance groove 37 .

[0092] The advantage of providing the avoidance groove 37 is that by changing the depth of the avoidance groove 37, the extent to which the inner end portion 24 extends into the avoidance groove 37 can be changed, thereby changing the opening angle of the splint 1 and the splint 2, thereby clamping objects of different thicknesses.

[0093] like Figure 3As shown, both the plywood 1 and the plywood 2 are semicircular arc plates, and the edges of the mattress are generally rounded, so the semicircular arc plates can better fit the curvature of the edges of the mattress. The design of the semicircular arc plates can also be used to organize the wires by curling the wires between the plywood 1 and the plywood 2.

[0094] Combine Figure 2 As can be seen, the rotation connection between the paddle 3 and the splint 1 is that first, a shaft 1 35 is provided on both sides of the paddle 3, and the shaft 1 35 is located between the paddle end 31 and the push end 32. At the same time, the two side walls of the chamber 13 are provided with placement holes 14.

[0095] Therefore, in actual use, the paddle 3 can be rotated and placed on the clamping plate 1 by the structure that the rotating shaft 1 35 is inserted into the placement hole 14 and rotates in the placement hole 14.

[0096] At the same time, in order to limit the position of the pick 3, bosses 15 are provided on both side walls of the chamber 13, and abutment 36 is provided between the toggle end 31 and the shaft 1 35. The toggle end 31 and the bosses 15 abut against each other to limit the position of the pick 3, thereby preventing the pick 3 from moving up and down. Figure 2 As shown, the abutting portion 36 is located between the dial end 31 and the rotating shaft 1 35 . Therefore, in this embodiment, there are two abutting portions 36 .

[0097] In addition, Figure 2 and Figure 3 As shown, a limit stop 19 is provided on one side of the placement hole 14. The function of the limit stop 19 is that when the paddle 3 is in the process of opening, a limit structure is necessarily required so that the paddle 3 can be limited at a reasonable angle, otherwise the paddle will continue to rotate around the rotating shaft 1 35 as the axis.

[0098] Therefore, in the present invention, a limit stop 19 is provided on one side of the placement hole 14, and further, the limit stop 19 is at least partially located on the rotation trajectory of the pushing end 32, thereby limiting the rotation of the paddle 3 by limiting the rotation of the pushing end 32.

[0099] The above specifically describes a fixture that applies force consistently and smoothly. However, if the fixture is to be able to clamp both thick and thin materials, it can only be designed with different sizes. It is not possible to use a single fixture to clamp objects of different thicknesses, or it can only meet the requirements within a relatively narrow thickness range. If you want to expand this range, it is impossible.

[0100] In order to solve the above problem, the present invention provides an adjustable gear fixing device. Based on the above structure, by adjusting the thickness of the clamped object, when the pushing end 32 and the inner end 24 are squeezed in the circumferential direction, the toggle end 31 has at least a first gear and a second gear according to the position of the toggle end 31.

[0101] Furthermore, the pushing end 32 has at least a first travel position corresponding to the first gear position and a second travel position corresponding to the second gear position; and the second travel position is closer to the inner end portion 24 than the first travel position;

[0102] Then, when the dial end 31 switches from the first gear position to the second gear position, the pushing end 32 enters the second gear position from the first stroke position.

[0103] That is to say, in actual use, when the paddle 3 switches from the unlocked state to the locked state, the pushing end 32 is actually in a process of gradually approaching the inner end portion 24 .

[0104] like Figure 6 As shown, since the clamped object is relatively thick, when it is rotated to the first gear, the pushing end 32 has been squeezed with the inner end 24 in the circumferential direction to maintain a locked state. At this time, the paddle 3 is in the first gear.

[0105] When the clamped object is a thin object, such as Figure 8 As shown, since the clamped article is relatively thin, when the first gear is rotated to the first position, the pushing end 32 and the inner end portion 24 are not squeezed in the circumferential direction and thus cannot maintain the locked state.

[0106] At this time, the paddle 3 continues to change toward the locked state until the toggle end 31 is in the second gear position, and the push end 32 has been squeezed with the inner end portion 24 in the circumferential direction to maintain the locked state, thereby clamping the thinner object.

[0107] The reason why the pushing end 32 can be squeezed against the inner end portion 24 in the circumferential direction in the second gear is that when rotating from the first gear to the second gear, the corresponding pushing end 32 moves from the first stroke position to the second stroke position, and the second stroke position is closer to the inner end portion 24 than the first stroke position, so that thinner objects can be clamped in the second gear.

[0108] The advantage of this design is that a fixture of one specification has different gears, which can clamp objects of different thicknesses, obtain a wider range, and truly achieve universal thickness, so that it can be applied to a wider range of application scenarios and improve product competitiveness.

[0109] Therefore, based on the above principle, in actual product development, the toggle end 31 may have multiple positions, such as a third and fourth position, in addition to the first and second positions. As long as the toggle end 31 is moved to different positions, the corresponding push end 32 can change its circumferential distance from the inner end portion 24, thereby enabling the clamping of objects of different thicknesses.

[0110] That is to say, in the present invention, the number of gears can be set according to demand and is not limited to only two gears. In this way, multiple gears can be designed when the size meets the requirements of the application scenario, thereby being applicable to a wider range of application scenarios.

[0111] Next, the above technical solution is described in detail through three embodiments.

[0112] [Example 1]

[0113] like Figure 6-9 As shown, the pushing end 32 includes two limiting portions, and the two limiting portions gradually approach the inner end portion 24 when switching from the first gear to the second gear.

[0114] Specifically, if Figure 9 As shown, the pushing end 32 has at least a first limiting portion 331 and a second limiting portion 332 ; the second limiting portion 332 is closer to the inner end portion 24 than the first limiting portion 331 .

[0115] At the same time, a rotating shaft 35 is provided on both sides of the paddle 3, and the rotating shaft 35 is located between the paddle end 31 and the push end 32;

[0116] In actual use, when the toggle end 31 is switched from the first gear to the second gear, the first limiting portion 331 and the second limiting portion 332 both rotate around the rotating shaft 1 35 .

[0117] At this time, if the clamped article is a relatively thick article, when the dial end 31 is in the first gear position, the first limiting portion 331 abuts against the inner end portion 24 to achieve locking.

[0118] If the object to be clamped is thin, the toggle end 31 does not abut against the inner end portion 24 in the circumferential direction when the toggle end 31 is in the first position, so the toggle end 31 continues to rotate until the toggle end 31 is in the second position, at which point the second limiting portion 332 abuts against the inner end portion 24 to achieve locking. In other words, the first limiting portion 331 switches to the second limiting portion 332 abutting against the inner end portion 24 to achieve clamping of the thin object.

[0119] It should be pointed out that if Figure 10As shown, in order to obtain more gear positions, the number of limiter portions can be configured according to actual needs. The configuration method is to configure additional limiter portions of different lengths and numbers along the direction from the first limiter portion 331 to the second limiter portion 332. Moreover, the length of the limiter portions gradually increases as they extend from the first limiter portion 331 to the second limiter portion 332, gradually approaching the inner end portion 24. Of course, in order to match the size design, the dimensions of the first limiter portion 331 and the second limiter portion 332, or the distance from the first limiter portion 331 to the second limiter portion 332 and the inner end portion 24, need to be recalculated.

[0120] The direction from the first limiting portion 331 to the second limiting portion 332 here refers to the direction from the first limiting portion 331 to the second limiting portion 332. Figure 9-10 As shown, the direction from the outside of the splint 1 to the inside of the splint 1, that is, the direction from left to right in the figure, does not limit the first limiting portion 331 to be the outermost or leftmost limiting portion, and does not limit the second limiting portion 332 to be the innermost or rightmost limiting portion.

[0121] The advantage of this embodiment is that it essentially follows the previous structure, with only a new stopper added to the push end 32, resulting in minimal structural changes. It also maintains the effect of eliminating the need for a paddle hook, while also ensuring relatively stable force during paddle rotation. Furthermore, if multiple gears are desired, simply add the corresponding number of stoppers.

[0122] <Variation 1>

[0123] like Figure 10 As shown, there are three limiting parts, including a first limiting part 331 and a second limiting part 332, a third limiting part 333, and even a fourth limiting part 334. Thus, the fixing device has three or even more gears, which can be more widely used to clamp objects of different thicknesses.

[0124] [Example 2]

[0125] like Figure 11-15 As shown, in this embodiment, the paddle 3 further has a rotating shaft 1 35 configured on both sides of the paddle 3, and the rotating shaft 1 35 is located between the paddle end 31 and the push end 32; the splint 1 has a slot 18, and in actual use, the rotating shaft 1 35 can slide in the slot 18.

[0126] In other words, the paddle 3 and the clamping plate 1 are relatively slidable. Therefore, when the paddle 3 is switched from the first position to the second position, the rotating shaft 1 35 of the paddle 3 slides within the locking slot 18, causing the entire paddle 3 to move closer to the inner end 24, thereby switching the pushing end 32 from the first travel position to the second travel position.

[0127] In order to achieve the above purpose, in this embodiment, the end of the rotating shaft 35 has at least: a first protrusion 351 and a second protrusion 352.

[0128] Moreover, when the paddle 3 is in the first gear position, the first protrusion 351 corresponds to the first travel position; and

[0129] The second protrusion 352 corresponds to the second travel position when the paddle 3 is in the second gear position;

[0130] That is to say, when the paddle 3 switches from the first gear position to the second gear position, the end of the rotating shaft 35 switches from the first protrusion 351 abutting against the slot 18 to the second protrusion 352 abutting against the slot 18; the corresponding pushing end 32 moves from the first stroke position to the second stroke position and then pushes the paddle 3 toward the inner end 24.

[0131] Look specifically Figure 11 and Figure 12 , Figure 11 is a perspective view of the paddle 3 when the paddle end 31 is in the first gear position and the push end 32 is in the first travel position; Figure 12 It is a perspective view when the dial end 31 of the paddle 3 is in the second gear position and the push end 32 is in the second stroke position.

[0132] In the above two figures, the dotted lines represent invisible lines that should be hidden. In order to better express the structure of this embodiment, the structural relationship between the plectrum 3 and the splint 1 is shown through the dotted lines.

[0133] In particular, Figure 11 and Figure 12 In the figure, there are black bold lines, which are mainly used to show the structure of the card slot 18 in the splint 1 and to highlight the structural relationship between the card slot 18 and the first protrusion 351 and the second protrusion 352 on the shaft 1 35.

[0134] Therefore, it can be seen from the above two figures that in this embodiment, when switching from the first gear to the second gear, since the curvature of the second protrusion 352 is greater than the curvature of the first protrusion 351, the paddle 3 is Figure 11 Continue to turn to Figure 12 During the clamping process, as the position of the paddle 3 against the clamping slot 18 changes, the paddle 3 gradually approaches the inner end 24 , thereby being able to adapt to clamping thinner objects.

[0135] In order to avoid the influence of dotted lines on the viewing effect, in this embodiment, Figure 151 is a cross-sectional view after a portion of the splint 1 is cut away, from which the assembly relationship between the rotating shaft 1 35 and the clamping slot 18 can be seen.

[0136] It should also be noted that in this embodiment, in addition to the first protrusion 351 and the second protrusion 352, multiple protrusions, such as a third protrusion and a fourth protrusion, can be designed according to actual gear requirements. As long as the corresponding rotating shaft 1 35 can change the distance between the pushing end 32 and the inner end 24 of the paddle 3 during rotation, multiple different gears can be formed to accommodate the need to clamp objects of varying thicknesses.

[0137] In addition, Figure 13-14 As shown, the first protrusion 351 includes a limiting edge 353, and the locking slot 18 is also formed with a limiting recess 181 adapted to the limiting edge 353. This design allows the rotating shaft 1 35 to be stably confined in the locking slot 18, thereby maintaining a stable locking.

[0138] like Figure 12 As shown, when the paddle 3 is switched from the first gear to the second gear, the second protrusion 352 abuts against the lower end portion on the right side of the limiting recess 181, so that it can remain locked even when it is rotated to the second gear.

[0139] Moreover, in this embodiment, the slot 18 is an open slot, which can reduce the difficulty of installing the paddle.

[0140] The effect of this embodiment is that by controlling the degree of protrusion of the first protrusion 351 and the second protrusion 352, the sliding distance of the paddle in the slide groove can be controlled, thereby controlling the distance between the pushing end 32 and the inner end 24, thereby being able to adapt to the needs of clamping objects of different thicknesses.

[0141] <Variation 2>

[0142] In this variation, the first protrusion 351 remains unchanged, while the second protrusion 352 changes according to the involute arc. This design allows for more flexible and precise control of the distance between the pushing end 32 and the inner end 24, thereby enabling clamping of objects of various thicknesses, achieving an almost stepless gear adjustment effect, and obtaining the most suitable clamping position.

[0143] [Example 3]

[0144] Compared with the second embodiment, this embodiment has the following differences:

[0145] like Figure 16-23 As shown, a cavity 13 is provided on the splint 1, and the paddle 3 is rotatably provided in the cavity 13; and bosses 15 are provided on both side walls of the cavity 13 to protrude inwardly, and the bosses 15 are used to hinder the rotation of the paddle.

[0146] At the same time, a support portion 36 is provided between the dial end 31 and the rotating shaft 1 35, and a support protrusion 38 is provided on the support portion 36. Figure 21 As shown, the abutting protrusion 38 is located at the upper end of the pushing end 32 , or even at the junction between the pushing end 32 and the dial end 31 .

[0147] The function of the abutment protrusion 38 in this embodiment is as follows: the abutment protrusion 38 corresponds to the second travel position, that is, when the paddle 3 rotates from the first gear position to the second gear position, the abutment protrusion 38 moves from the outside of the splint 1 to the inside of the splint 1 and abuts against the inner wall of the splint 1, so that the abutment protrusion 38 pushes the pushing end 32 toward the inner end portion 24.

[0148] A further specific preferred structure is that when the paddle 3 switches from the first gear position to the second gear position, the abutting protrusion 38 moves from the outside of the boss 15 to the lower side of the boss 15 and abuts against the lower side wall of the boss 15 .

[0149] Look specifically Figure 16 and Figure 17 , Figure 16 This is a perspective view of the paddle in the third embodiment when the paddle end 31 is in the first gear position and the push end 32 is in the first travel position; Figure 17 It is a perspective view of the paddle in the third embodiment when the paddle end 31 is in the second gear position and the push end 32 is in the second stroke position.

[0150] In the above two figures, the dotted lines represent invisible lines that should be hidden. In order to better express the structure of this embodiment, the structural relationship between the plectrum 3 and the splint 1 is shown through the dotted lines.

[0151] In particular, Figure 16 and Figure 17 In the figure, there are black bold lines, which are mainly used to show the structure between the abutting protrusion 38 on the paddle 3 and the boss 15 in the splint 1, and to highlight the structural relationship between the abutting protrusion 38 and the boss 15.

[0152] Therefore, it can be seen from the above two figures that when the paddle 3 switches from the first gear to the second gear, the toggle end 31 is Figure 16 The position continues to rotate to Figure 17 During the rotation, the position of the protrusion 38 moves downward along the slot 18 toward the second clamping plate 2, thereby moving closer to the inner end 24, thereby enabling the clamping of thinner items.

[0153] In order to avoid the influence of dotted lines on the viewing effect, in this embodiment, Figure 191 is a cross-sectional view after a portion of the splint 1 is cut away, from which the assembly relationship between the rotating shaft 1 35 and the boss 15 can be seen.

[0154] Then, the distance between the pushing end 32 and the inner end 24 of the paddle 3 is changed, thereby adapting to the needs of clamping objects of different thicknesses.

[0155] Therefore, in this embodiment, the number of the abutting protrusions 38 can be two, three, or even more. As long as the abutting protrusions 38 closer to the boss 15 are shorter and the abutting protrusions 38 farther from the boss 15 are longer, the abutting protrusions 38 of different lengths can penetrate the underside of the boss 15, thereby driving the paddle to slide toward the second clamping plate 2 by different distances, thereby clamping objects of different thicknesses.

[0156] To reduce resistance during the rotation of the paddle 3, the upper end of the abutment protrusion 38 is formed with a circular arc surface 381. The outer height of the circular arc surface is higher than the inner height of the circular arc surface. The design of the circular arc surface 381 reduces resistance and prevents jamming. The outer height of the circular arc surface is higher than the inner height of the circular arc surface, which can drive the paddle 3 to move.

[0157] The outer side of the arc surface and the inner side of the arc surface are relative concepts. Figure 21 As shown, it also refers to the left side of the arc surface and the right side of the arc surface.

[0158] Therefore, this design not only realizes the function of driving the paddle to slide, but also reduces resistance and improves the aesthetics of the product.

[0159] <Variation 3>

[0160] In the third embodiment, the abutting protrusion 38 is provided on the abutting portion 36. In this modified example, Figure 23 As shown, the abutment protrusion 38 is provided on the lower side of the boss 15 .

[0161] The advantage of this design is that, during the rotation of the paddle, the abutting portion 36 will slide along the slide groove under the action of the abutting protrusion 38 located on the lower side of the boss 15, thereby also changing the distance between the pushing end 32 and the inner end 24.

[0162] <Variation 4>

[0163] In this modified example, the number of the abutting protrusions 38 is two. Figure 21 As shown, the two abutting protrusions 38 are a first abutting protrusion 38-1 on the left and a second abutting protrusion 38-2 on the right. The advantage of this design is that it has one more gear than the third embodiment, so that it can more accurately match items of different thicknesses.
