Description

Technical Field

[0001] This invention belongs to the technical field of daily necessities, and specifically refers to a universal fixing device. Background Technology

[0002] A clip is used to hold sheets and mattresses in place, preventing them from shifting or wrinkling. However, commonly used clips are fitted over the sheets and mattresses, such as the invention patent with patent number 2019214292183, entitled "A Sheet Holding Device." Although this patent is applicable to all households and convenient to use, because it is fitted over the sheets and mattresses, the clips need to be fitted over the sheets and mattresses from both ends, and then the clips need to be moved to the middle to reach the desired holding position. A certain amount of force is also required to move it to the desired holding position. Therefore, it is not possible to clamp directly from the desired position and it is also laborious.

[0003] Meanwhile, there is also a utility model patent with patent number 2019205015942, which specifically discloses a quilt fastener. However, while this patented technology solves the aforementioned problems of laborious operation and fixed position, the solution only has one clamping position. If designed for thin items, it cannot achieve locking between the upper and lower clamps for thicker items; conversely, if designed for thicker items, locking the upper and lower clamps will not clamp thinner items. Summary of the Invention

[0004] The purpose of this invention is to provide a universal fixing device that is applicable to items of different thicknesses.

[0005] The objective of this invention is achieved as follows: a universal fixing device includes a first clamp and a second clamp, wherein the second clamp is hinged to the first clamp and allows relative rotation; the first clamp and the second clamp close together to clamp an object; the fixing device further includes:

[0006] A paddle is rotatably mounted on the clamping plate and is movable relative to the clamping plate; the paddle has an unlocked state and a locked state.

[0007] The paddle has the following characteristics:

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

[0009] The pushing end is at least partially located on the rotational trajectory of the two ends of the clamping plate; when the lever is in the locked state, the pushing end of the lever and the inner end of the second clamping plate are pressed together in the circumferential direction to maintain the locked state, so that the first clamping plate and the second clamping plate remain closed; and

[0010] The abutting protrusion is located at the upper end of the pushing end, and the movement track of the abutting protrusion at least partially overlaps with the first clamping plate, and after the overlapping, further rotation of the pushing end makes the pushing end move towards the inner end.

[0011] Preferably, the two sides of the push piece are provided with the rotating shaft I;

[0012] The abutting part is arranged between the pushing end and the rotating shaft I, and the abutting protrusion is arranged on the abutting part.

[0013] Preferably, the first clamping plate is provided with a chamber, and the push piece is arranged in the chamber in a rotating mode;

[0014] The two side walls of the chamber are provided with protrusions, and the protrusions are used for blocking the rotation of the push piece.

[0015] When the abutting protrusion rotates with the pushing end, the abutting protrusion moves from outside the protrusion to inside the protrusion and abuts on the inner wall of the protrusion, so that the pushing end moves towards the inner end.

[0016] Preferably, the first clamping plate is provided with a clamping groove.

[0017] The rotating shaft I is arranged in the clamping groove in a slidable mode.

[0018] Preferably, the upper end of the abutting protrusion is formed with a circular arc surface, and the height of the outer side of the circular arc surface is higher than the height of the inner side of the circular arc surface.

[0019] Preferably, the locking state of the pushing end at least has a first gear position when thick materials are clamped and a second gear position when thin materials are clamped; and when the thin materials are clamped and in the locking state, the pushing end sequentially passes through the first gear position and the second gear position.

[0020] Preferably, the abutting protrusion is located at the two sides of the upper end of the pushing end, and when the abutting protrusion rotates with the pushing end, the abutting protrusion moves from outside the chamber to inside the chamber and abuts on the inner wall of the chamber, so that the pushing end moves towards the inner end.

[0021] The present application has the following prominent and beneficial technical effects compared with the prior art:

[0022] 1. When the pushing end of the push piece moves from the first gear position to the second gear position, the pushing end moves from the first stroke position to the second stroke position, and the second stroke position is closer to the inner end than the first stroke position, so that the second gear position can clamp thinner materials compared with the materials that can be clamped when the first gear position is in the first gear position. That is, the function of clamping thick materials is switched to the function of clamping thin materials. Finally, the gear position is adjusted, so that a fixed device can be used for clamping thin materials and thick materials at the same time.

[0026] 5、The present application in the clamping plate one and clamping plate two fold and dial piece in the locked state, because the push end and the inner end of clamping plate two in the circumferential direction extrusion, so as not to need through the dial piece hook clamping plate one or clamping plate two, can realize, clamping plate one and clamping plate two keep folding. This can be in the process of clamping the article, more relaxed and labor saving.

Detailed Implementation

[0055] The present invention will be further described below with reference to specific embodiments.

[0056] like Figures 1-4 As shown, an adjustable fixing device includes a first clamp 1 and a second clamp 2, which are hinged to each other. Therefore, in actual use, the first clamp 1 and the second clamp 2 can open and close relative to each other.

[0057] Combination Figures 2-3 It can be seen that the rotational connection between clamping plate 1 and clamping plate 2 is achieved by firstly, connecting plates 16 are provided on both sides of clamping plate 1, and one end of the connecting plate 16 is provided with a mounting hole 17. At the same time, rotating shafts 23 are provided on both sides of clamping plate 2.

[0058] In actual use, the clamping plate 2 can be rotatably mounted on the clamping plate 1 by means of the structure in which the rotating shaft 23 passes through the mounting hole 17 and rotates within the mounting hole 17.

[0059] Meanwhile, a chamber 13 is provided on the clamp 1, and a paddle 3 is rotatably provided in the chamber 13, with the two ends of the paddle 3 being the paddle end 31 and the push end 32, respectively.

[0060] Therefore, in actual use, such as Figure 6 As shown, when the lever 3 is in the locked state, the pushing end 32 of the lever and the inner end 24 of the second clamp 2 are pressed together in the circumferential direction to maintain the locked state, so that the first clamp 1 and the second clamp 2 remain closed. Therefore, it is not necessary to lock the first clamp or the second clamp with the lever to keep the first clamp and the second clamp closed. This makes clamping objects easier and less strenuous.

[0061] This is because, in existing technologies, some solutions involve using a hook at the end of a lever to engage either clamp 1 or clamp 2, ultimately keeping clamp 1 and clamp 2 closed. However, this solution requires considerable force to engage the hook at the end, and it also generates noise, making it inconvenient to use.

[0062] At the same time, the hook needs to be disconnected from the clamping plate 1 and the clamping plate 2, and a large explosive force needs to be applied to disconnect the hook, and noise is generated.

[0063] In the application, as shown in the drawings, Figures 2-3 The clamping plate 1 is provided with a connecting groove 11 at the front end, and the actuating end 31 is placed in the connecting groove 11 to limit the inward rotation of the actuating end 31, and the outer end of the actuating end 31 is on the same plane as the outer end of the clamping plate 1, thereby providing comfort to the user.

[0064] At the same time, it is convenient for the user to actuate the actuating end 31, and a space 12 can be provided between the connecting groove 11 and the actuating end 31 to facilitate the user to actuate the actuating end 31.

[0065] Alternatively, a recess is formed in the inner wall of the actuating end 31 to facilitate the user to actuate the actuating end 31, or a combination of the two.

[0066] Therefore, in this embodiment, the actuating end 31 is only required to abut against the connecting groove 11 to keep the clamping plate 1 and the clamping plate 2 closed, and the structure of the hook is no longer required, thereby avoiding noise and making the locking and unlocking processes easier and more labor-saving.

[0067] In order to avoid the situation that the actuating piece 3 is loose and the clamping plate 1 and the clamping plate 2 are suddenly opened, the rear end of the pushing end 32 abuts against the front side of the upper end of the clamping plate 2, that is, the pushing end 32 and the clamping plate 2 are tightly fitted with each other to limit the rotation of the actuating piece 3 and avoid the sudden opening of the clamping plate 1 and the clamping plate 2.

[0068] That is, in this embodiment, the inner side of the inner end portion 24 is provided with a guide slope 25, and the guide slope 25 is in interference fit with the pushing end 32, so that the actuating piece 3 needs to be in a certain external force to enter or exit the locking state.

[0069] Therefore, in actual use, a certain force is required to rotate the actuating piece 3, thereby opening the clamping plate 1 and the clamping plate 2. The application can also be used for sealing of snack moisture-proof, and clamping of other household supplies, such as clamping of tablecloth or clamping of curtain. Therefore, the adjustable fixed device in this embodiment can clamp the thinner snack bag and the thicker tablecloth and curtain, and even the thicker mattress edge, and can clamp both thin and thick.

[0070] As shown in the drawings, Figure 3 The guide 21 is provided with an L-shaped guide groove 22, and the rear end of the pushing end 32 pushes the clamping plate 2 outward along the guide groove 22 to rotate, thereby opening the clamping plate 1 and the clamping plate 2.

[0071] The L-shaped guide slot 22 has a larger contact area with the pushing end 32 than a flat surface, and in the guiding process, the rear end of the pushing end 32 finally falls into the notch of the L-shaped guide slot 22, thereby avoiding the pushing end 32 from being separated from the guide 21.

[0072] In addition, in the present embodiment, as shown in Figs. Figure 6 , 8 9 and 10, one side of the knob 3 is formed with an avoiding slot 37, and the outer wall surface of the avoiding slot 37 is at least partially located on the movement track of the inner end 24 when the clamping plate 2 is opened;

[0073] And with the increase of the opening angle of the clamping plate 1 and the clamping plate 2, the inner end 24 further extends into the avoiding slot 37.

[0074] That is to say, when the knob 3 starts to rotate and is in the unlocked state, the knob 3 has rotated a certain angle, and compared with the locked state, the angle towards which the avoiding slot 37 changes. As shown in Figs. Figure 6 and Figure 8 show the change of the clamping plate 1 and the clamping plate 2 from the state of being closed and clamped to the state of being opened.

[0075] In which, after being opened to a certain extent, the inner end 24 of the clamping plate 2 has been located in the avoiding slot 37 after passing through the set rotation track, and in the extreme case, the inner end 24 can abut against the outer wall surface of the avoiding slot 37.

[0076] The advantage of setting the avoiding slot 37 is that by changing the depth of the avoiding slot 37, the degree of the inner end 24 extending into the avoiding slot 37 can be changed, thereby changing the opening angle of the clamping plate 1 and the clamping plate 2, so as to clamp articles of different thicknesses.

[0077] As shown in Figs. Figure 3 The clamping plate 1 and the clamping plate 2 are both semicircular arc plates, and the edge of the mattress is generally rounded, so that the semicircular arc plates can better fit the curvature of the edge of the mattress. The design of the semicircular arc plates can also be used to wind the wire between the clamping plate 1 and the clamping plate 2 for wire arrangement.

[0078] It can be known from Figs. Figure 2 that the knob 3 and the clamping plate 1 are rotationally connected. First, the knob 3 is provided with a rotation shaft 35 on both sides, and the rotation shaft 35 is located between the knob end 31 and the pushing end 32. At the same time, the two side walls of the chamber 13 are provided with placing holes 14.

[0079] Thus, in actual use, the rotation shaft 35 can be arranged in the placing hole 14 and rotated in the placing hole 14, so as to rotationally arrange the knob 3 on the clamping plate 1.

[0080] Meanwhile, in order to limit the position of the dial 3, a boss 15 is arranged on the inner side of the two side walls of the cavity 13, and a abutting part 36 is arranged between the dial end 31 and the rotating shaft 35, and the abutting part 36 abuts against the boss 15, thereby limiting the position of the dial 3, and avoiding the up and down movement of the dial 3. Here, the dial end 31 and the rotating shaft 35 refer to the state shown in Figure 2 Fig. 2, and the position of the abutting part 36 is between the dial end 31 and the rotating shaft 35, so in this embodiment, the abutting part 36 has two.

[0081] In addition, as shown in Figure 2 and Figure 3 Fig. 3, a limiting stop 19 is arranged on one side of the placement hole 14, and the limiting stop 19 has the function of limiting the dial 3 at a reasonable angle during the opening process of the dial 3, otherwise the dial will continue to rotate around the rotating shaft 35.

[0082] Therefore, in the application, the limiting stop 19 is arranged on one side of the placement hole 14, and at least part of the limiting stop 19 is located on the rotating track of the pushing end 32, thereby limiting the rotation of the dial 3 by limiting the rotation of the pushing end 32.

[0083] The above specifically introduces a fixed device with smooth and consistent force application, but if the above fixed device wants to realize clamping of thick and thin objects, it can only change the size to design fixed devices of different specifications, and it cannot realize clamping of objects of different thicknesses with a fixed device of one specification, or it can only satisfy a relatively narrow range of thicknesses. If you want to expand this range, it cannot be realized.

[0084] In order to solve the above problems, in the present application, a fixed device with adjustable gears is provided, and on the basis of the above structure, when the pushing end 32 and the inner end 24 are extruded in the circumferential direction according to the position of the dial end 31, the dial end 31 has at least a first gear and a second gear;

[0085] Moreover, the pushing end 32 has at least a first stroke position corresponding to the first gear, and a second stroke position corresponding to the second gear; and the second stroke position is closer to the inner end 24 than the first stroke position;

[0086] Furthermore, when the dial end 31 is switched from the first gear to the second gear, the pushing end 32 enters the second stroke position from the first stroke.

[0087] That is, in actual use, when the dial 3 is switched from the unlocked state to the locked state, the pushing end 32 is actually in the process of gradually approaching the inner end 24.

[0088] As Figure 6 shown, since the clamped article is thicker, when rotated to the first gear, the pushing end 32 has been extruded with the inner end 24 in the circumferential direction to maintain the locking state, and the paddle 3 is in the first gear at this time.

[0089] When the clamped article is a thinner article, as Figure 8 shown, since the clamped article is thinner, when rotated to the first gear, the pushing end 32 has not been extruded with the inner end 24 in the circumferential direction to maintain the locking state.

[0090] At this time, the paddle 3 continues to change towards the locking state until the pushing end 32 has been extruded with the inner end 24 in the circumferential direction to maintain the locking state when the pushing end 31 is in the second gear, thereby clamping the thinner article.

[0091] The reason why the pushing end 32 has been extruded with the inner end 24 in the circumferential direction at the second gear is that the pushing end 32 moves from the first stroke position to the second stroke position when rotating from the first gear to the second gear, and the second stroke position is closer to the inner end 24 than the first stroke position, thereby being able to clamp thinner articles at the second gear.

[0092] The advantage of this design is that different gears are provided on a fixed device of one specification, thereby being able to clamp articles of different thicknesses, obtaining a wider range, and truly realizing thickness versatility, thereby being applicable to more extensive application scenarios and improving product competitiveness.

[0093] Therefore, based on the above principle, in the actual product development, the pushing end 31 can have third, fourth, and multiple gears in addition to the first and second gears. Only when the corresponding pushing end 32 changes the distance from the inner end 24 in the circumferential direction when the pushing end 31 moves to different gears, can articles of different thicknesses be clamped.

[0094] That is, in the present application, the number of gears can be set according to requirements, and is not limited to only two gears. Such a design of multiple gears in the case of size meeting the application scenario requirements can be applied to more extensive application scenarios.

[0095] Next, three embodiments will be described in detail.

[0096]

Embodiment One

[0097] As Figures 6-9 shown, the pushing end 32 includes two limiting positions, and the two limiting positions gradually approach the inner end 24 when switching from the first gear to the second gear.

[0098] Specifically, as shown in Figure 9 The pushing end 32 has at least a first limiting position 331 and a second limiting position 332; the second limiting position 332 is closer to the inner end 24 than the first limiting position 331.

[0099] Meanwhile, the both sides of the poking piece 3 are provided with a rotating shaft 35, and the rotating shaft 35 is located between the poking end 31 and the pushing end 32.

[0100] In actual use, when the poking end 31 is switched from the first gear to the second gear, both the first limiting position 331 and the second limiting position 332 rotate around the rotating shaft 35.

[0101] At this time, if the clamped article is a relatively thick article, when the poking end 31 is in the first gear, the first limiting position 331 abuts against the inner end 24 to achieve locking.

[0102] If the clamped article is a relatively thin article, when the poking end 31 is in the first gear, it does not abut against the inner end 24 in the circumferential direction, so the poking end 31 continues to rotate until the poking end 31 is in the second gear, and the second limiting position 332 abuts against the inner end 24 to achieve locking. That is, the first limiting position 331 is switched to the second limiting position 332 to abut against the inner end 24 to clamp the relatively thin article.

[0103] It should be noted that, as shown in Figure 10 In order to obtain more gears, the number of limiting positions can be configured according to actual needs, and the configuration method is to further configure limiting positions of different lengths and different numbers in the direction from the first limiting position 331 to the second limiting position 332; and the length of the limiting position gradually increases and gradually approaches the inner end 24 in the direction from the first limiting position 331 to the second limiting position 332. Of course, in order to correspond to the size design, the size of the first limiting position 331 and the second limiting position 332 or the distance between the first limiting position 331 and the second limiting position 332 and the inner end 24 needs to be calculated again.

[0104] Here, the direction from the first limiting position 331 to the second limiting position 332 refers to the direction from the outer side of the clamping plate 1 to the inner side of the clamping plate 1, that is, the direction from left to right in the figure, as shown in Figures 9-10 That is, the first limiting position 331 is not limited to be the outermost or leftmost limiting position, and the second limiting position 332 is not limited to be the innermost or rightmost limiting position.

[0105] The effect of the embodiment is that the previous structure is basically followed, and only a new limiting position is added at the pushing end 32, so the structure is changed little. Moreover, the effect of not needing to pull the piece to hook is maintained, and the force is relatively stable during the rotation of the piece. Moreover, if multiple gears are needed, only the corresponding number of limiting positions are needed.

[0106] <Variant example one>

[0107] As shown in Figure 10 , the number of limiting positions is three, in addition to the first limiting position 331 and the second limiting position 332, there is also a third limiting position 333, and even a fourth limiting position 334. Thus, the fixing device has three gears or even more gears, which can be more widely used to clamp objects of different thicknesses.

[0108] [Example two]

[0109] As shown in Figures 11-15 , in this embodiment, the piece 3 also has a rotating shaft one 35 arranged on both sides of the piece 3, and the rotating shaft one 35 is located between the pushing end 32 and the pushing end 32; the clamping plate one 1 has a clamping groove 18, and in actual use, the rotating shaft one 35 is slidable in the clamping groove 18.

[0110] That is, the piece 3 and the clamping plate one 1 can slide relative to each other. Therefore, when the piece 3 is switched from the first gear to the second gear, the rotating shaft one 35 of the piece 3 is switched from the first stroke position to the second stroke position by sliding in the clamping groove 18, that is, the pushing end 32 is switched from the first stroke position to the second stroke position.

[0111] Among them, in order to achieve the above purpose, in this embodiment, the end of the rotating shaft one 35 at least has: a first protruding part 351 and a second protruding part 352.

[0112] Moreover, when the piece 3 is in the first gear, the first protruding part 351 corresponds to the first stroke position; and

[0113] the second protruding part 352, when the piece 3 is in the second gear, the second protruding part 352 corresponds to the second stroke position;

[0114] That is, when the piece 3 is switched from the first gear to the second gear, the end of the rotating shaft one 35 is switched from the first protruding part 351 abutting against the clamping groove 18 to the second protruding part 352 abutting against the clamping groove 18; corresponding to the pushing end 32 moving from the first stroke position to the second stroke position and then pushing the piece 3 towards the inner end 24.

[0115] Specifically Figure 11 and Figure 12 , Figure 11is a perspective view of the shifting end 31 of the shifting piece 3 in the first gear and the pushing end 32 in the first stroke position; Figure 12 is a perspective view of the shifting end 31 of the shifting piece 3 in the second gear and the pushing end 32 in the second stroke position.

[0116] In the above two figures, the dashed lines represent the invisible lines that should be hidden. In order to better express the structure of the embodiment, the structural relationship between the shifting piece 3 and the clamping plate 1 is shown by the dashed lines.

[0117] In particular, in Figure 11 and Figure 12 , there are black thick lines, which are mainly used to show the structure of the clamping groove 18 in the clamping plate 1 and highlight the structural relationship between the clamping groove 18 and the first protruding part 351 and the second protruding part 352 on the rotating shaft 1.

[0118] Therefore, from the above two figures, it can be seen that in the embodiment, when switching from the first gear to the second gear, because the curvature of the second protruding part 352 is greater than that of the first protruding part 351, the shifting piece 3 gradually approaches the inner end 24 during the process of continuing to rotate from Figure 11 to Figure 12 , so as to adapt to clamping thinner objects.

[0119] In order to avoid the influence of the dashed lines on the view effect, in the embodiment, Figure 15 is a sectional view of the clamping plate 1 after cutting part of it, from which the assembly relationship between the rotating shaft 1 and the clamping groove 18 can be seen.

[0120] In addition, it should be pointed out that in the embodiment, in addition to the first protruding part 351 and the second protruding part 352, a third protruding part, a fourth protruding part, etc. can also be designed according to the actual gear requirements. As long as the distance between the pushing end 32 of the shifting piece 3 and the inner end 24 can be changed during the rotation of the rotating shaft 1, a plurality of different gears can be formed to adapt to the clamping requirements of objects with different thicknesses.

[0121] In addition, as shown in Figures 13-14 , the first protruding part 351 includes a limiting edge 353, and the clamping groove 18 is also formed with a limiting recess 181 adapted to the limiting edge 353. This design can stably limit the rotating shaft 1 in the clamping groove 18, thereby maintaining the stability of the locking.

[0122] As shown in Figure 12As shown, when the paddle 3 is switched from the first gear to the second gear, the second protrusion 352 abuts against the lower end of the right side of the limiting recess 181, so that it can remain locked even when rotated to the second gear.

[0123] Moreover, in this embodiment, the slot 18 is an open slot, which reduces the difficulty of installing the paddle.

[0124] The advantage of this embodiment is that by controlling the degree of protrusion of the first protrusion 351 and the second protrusion 352, the distance the paddle slides in the groove can be controlled, thereby controlling the distance between the pushing end 32 and the inner end 24, thus adapting to the needs of clamping items of different thicknesses.

[0125] <Variation Example 2>

[0126] In this modified example, the first protrusion 351 remains unchanged, while the second protrusion 352 changes according to the involute curvature. This design allows for more flexible and precise control of the distance between the pushing end 32 and the inner end 24, thereby enabling the clamping of items of various thicknesses and achieving a near stepless adjustment effect, thus obtaining the most suitable clamping position.

[0127]

Example 3

[0128] This embodiment differs from Embodiment 2 in the following ways:

[0129] like Figures 16-23 As shown, a chamber 13 is provided on the clamping plate 1, and the paddle 3 is rotatably disposed in the chamber 13; while protrusions 15 are provided on both sides of the chamber 13, which are used to prevent the paddle from rotating.

[0130] Meanwhile, a stop portion 36 is provided between the actuating end 31 and the rotating shaft 35, and a stop protrusion 38 is provided on the stop portion 36. Furthermore, as... Figure 21 As shown, the abutment protrusion 38 is located at the upper end of the push end 32, or even at the junction between the push end 32 and the actuating end 31.

[0131] The function of the abutment protrusion 38 in this embodiment is: the abutment protrusion 38 corresponds to the second travel position, that is, when the paddle 3 is rotated from the first position to the second position, the abutment protrusion 38 moves from the outside of the clamping plate 1 to the inside of the clamping plate 1 and abuts against the inner wall of the clamping plate 1, so that the abutment protrusion 38 pushes the pushing end 32 to move toward the inner end 24.

[0132] A more specific preferred structure is that when the paddle 3 switches from the first gear to the second gear, the abutment protrusion 38 moves from outside the boss 15 to the lower side of the boss 15 and abuts against the lower side wall of the boss 15.

[0133] Specifically looking at Figure 16 and Figure 17 , Figure 16 is a perspective view of the shifting end 31 of the shifting piece in the first gear and the pushing end 32 in the first stroke position in Example Three; Figure 17 is a perspective view of the shifting end 31 of the shifting piece in the second gear and the pushing end 32 in the second stroke position in Example Three.

[0134] In the above two figures, the dashed line represents the invisible line that should be hidden. In order to better express the structure of the embodiment, the structural relationship between the shifting piece 3 and the clamping plate 1 is shown by the dashed line.

[0135] In particular, in Figure 16 and Figure 17 , there are black thick lines, which are mainly used to show the structure between the abutting protrusions 38 on the shifting piece 3 and the boss 15 in the clamping plate 1, and to highlight the structural relationship between the abutting protrusions 38 and the boss 15.

[0136] Therefore, from the above two figures, it can be seen that when the shifting piece 3 is switched from the first gear to the second gear, the shifting end 31 is continuously rotated from the position of Figure 16 to the position of Figure 17 , and in the process of rotation, the movement of the position of the abutting protrusions 38 causes the shifting piece 3 to move downward along the clamping groove 18 towards the clamping plate 2 as a whole, thereby further approaching the inner end 24, so as to achieve the ability to clamp thinner objects.

[0137] In order to avoid the influence of the dashed line on the view effect, in the embodiment, Figure 19 is a sectional view of the clamping plate 1 after cutting part of it, from which the assembly relationship between the shaft 35 and the boss 15 can be seen.

[0138] Then the distance between the pushing end 32 of the shifting piece 3 and the inner end 24 is changed, thereby achieving the need to clamp objects of different thicknesses.

[0139] Therefore, in the embodiment, the number of 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 away from the boss 15 are longer, the abutting protrusions 38 of different lengths can enter the underside of the boss 15, thereby driving the shifting piece to slide towards the clamping plate 2 by different distances, thereby achieving clamping objects of different thicknesses.

[0140] At the same time, in order to reduce the resistance when the shifting piece 3 rotates, the upper end of the abutting protrusion 38 is formed with a circular arc surface 381, and the height of the outer side of the circular arc surface is higher than the height of the inner side of the circular arc surface. The design of the circular arc surface 381 can reduce the resistance and prevent jamming. Then the height of the outer side of the circular arc surface is higher than the height of the inner side of the circular arc surface, which can drive the shifting piece 3 to move.

[0141] The outer side of the arc surface and the inner side of the arc surface are relative concepts, as Figure 21 indicated, also refer to the left side of the arc surface and the right side of the arc surface.

[0142] Therefore, such design can not only realize the function of driving the slide to slide, but also reduce the resistance and improve the product aesthetics.

[0143] <Variant Three>

[0144] In the third embodiment, the abutting protrusion 38 is arranged on the abutting portion 36. In the present variant, as Figure 23 indicated, the abutting protrusion 38 is arranged on the lower side of the boss 15.

[0145] The advantage of such design is that the slide will slide along the sliding groove under the action of the abutting protrusion 38 arranged on the lower side of the boss 15 during the rotation of the slide. Thus, the distance between the pushing end 32 and the inner end portion 24 can also be changed.

[0146] <Variant Four>

[0147] In the present variant, the number of abutting protrusions 38 is two, as Figure 21 indicated, the two abutting protrusions 38 are respectively a first abutting protrusion 38-1 on the left side and a second abutting protrusion 38-2 on the right side. The advantage of such design is that compared with the third embodiment, there is one more gear, so that different thickness of the article can be matched more accurately.
