[0048] The present application embodiment provides a clamp 1, see Figures 1 to 7 The clamp 1 includes a clamp body 10 and a fastener 11.

[0049] It should be noted that the application field of the clamp 1 is not limited, and the present application is described by taking the application of the clamp 1 in the field of medical device technology as an example.

[0050] The clamping body 10 has a clamping space 10a and an interface 10b.

[0051] The clamping space 10 a extends along a first direction for passing the rail 2 , that is, the rail 2 passes through the clamping space 10 a along the first direction.

[0052] It can be understood that the track 2 refers to a general term for a structure used to cooperate with the clamping space 10a, and the track 2 can be a side rail, a slide rail, etc.

[0053] The interface 10b is used to plug in the accessory 3, which may be a medical device such as an operating table accessory, for example, an accessory 3 with a rod or an accessory 3 with a protruding portion, etc. The accessory 3 with a rod may be an accessory 3 that is entirely rod-shaped, or may be an accessory 3 composed of a rod and components of other shapes, with one end with the rod plugged into the interface 10b, for example, an accessory with a round support rod, an accessory with an elliptical support rod, an accessory with a rectangular support rod, etc.

[0054] The cross section of the interface 10b includes a first portion 10c and a second portion 10d which are connected to each other. In the first direction, the first end of the second portion 10d extends beyond the first portion 10c. In the second direction, the first portion 10c and the clamping space 10a are respectively located on both sides of the second portion 10d.

[0055] It can be understood that the clamping space 10a is connected to the interface 10b, and the first part 10c is connected to the clamping space 10a through the second part 10d, so that when the accessory 3 is inserted into the interface 10b, it can abut against the track 2.

[0056] It should be noted that the setting method of the interface 10b is not limited. For example, the interface 10b can penetrate at least one end of the clamping body 10 along the third direction along the third direction. Specifically, the interface 10b can penetrate one end of the clamping body 10 along the third direction along the third direction. One end of the interface 10b is open and the other end is closed. The accessory 3 can be inserted into the interface 10b from the open end and abut against the closed end; or, the interface 10b can be along both ends of the clamping body 10 along the third direction along the third direction. In this way, both ends of the interface 10b are open, and when the accessory 3 is inserted into the interface 10b, it passes through the two openings of the interface 10b.

[0057] It can be understood that the third direction is perpendicular to the first direction and the second direction, and the insertion direction of the attachment 3 is consistent with the third direction.

[0058] The side wall of the first portion 10c is provided with a connecting hole 10e, and one end of the fastener 11 passes through the connecting hole 10e and is used to abut against the accessory 3 passing through the interface 10b.

[0059] Exemplarily, the inner wall of the connecting hole 10e has an internal thread, and the fastener 11 is a part with an external thread that can be adapted to the internal thread of the connecting hole 10e. In this way, the fastener 11 can be moved toward the side close to the clamping space 10a by rotating to abut against the accessory 3 penetrated through the interface 10b.

[0060] When the size of the clamped accessory 3 along the second direction is smaller than the size of the second part 10d in the second direction, the clamped accessory 3 is only accommodated in the second part 10d, and the clamped accessory 3 is fixed by abutting against the inner surface of the rail 2, the fastener 11 and the first end of the second part 10d passing through the clamping space 10a.

[0061] Specifically, the track 2 is penetrated in the clamping space 10a, and the second part 10d is close to the clamping space 10a. The accessory 3 can be inserted in the second part 10d, and the fastener 11 passes through the connecting hole 10e and moves toward the second part 10d via the first part 10c to abut against the side of the accessory 3 close to the first part 10c. Under the abutting action of the fastener 11, the accessory 3 moves toward the side close to the clamping space 10a until the accessory 3 is tightly attached to the track 2 along the second direction and the side close to the clamping space 10a, and the gap between the accessory 3 and the track 2 is eliminated, and the accessory 3 cannot move in the second direction. The side of the accessory 3 along the first direction abuts against the inner surface of the first end of the second part 10d, and the accessory 3 cannot move in the first direction. At this time, the accessory 3 is fixed in the second part 10d under the cooperation of the abutting force of the fastener 11, the track 2, and the inner surface of the first end of the second part 10d, and will not shake or move.

[0062] When the size of the clamped accessory 3 along the second direction is larger than the size of the second part 10d in the second direction, that is, at this time, the clamped accessory 3 cannot be accommodated by the second part 10d, the clamped accessory 3 is accommodated in the first part 10c and the second part 10d, and the clamped accessory 3 is fixed by abutting against the rail 2, the fastener 11, and the inner surface of the first part 10c passing through the clamping space 10a.

[0063] Specifically, the track 2 is passed through the clamping space 10a, the accessory 3 is inserted into the first part 10c and the second part 10d, the fastener 11 passes through the connecting hole 10e and moves toward the side close to the clamping space 10a to abut against the side of the accessory 3 close to the first part 10c. Under the abutting action of the fastener 11, the accessory 3 moves toward the side close to the clamping space 10a until the accessory 3 is tightly attached to the track 2 along the second direction and the side close to the clamping space 10a, the gap between the accessory 3 and the track 2 is eliminated, the accessory 3 cannot move along the second direction, and the side of the accessory 3 along the first direction abuts against the inner surface of the first part 10c, and the accessory 3 cannot move along the first direction. At this time, the accessory 3 is fixed in the interface 10b under the cooperation of the abutting force of the fastener 11, the track 2, and the inner surface of the first part 10c, and will not shake or move.

[0064] The clamp 1 provided in the embodiment of the present application is a single clamp 1 that can meet the clamping requirements of different types of accessories 3, and the accessory 3 plugged into the interface 10b can be locked, reducing the probability of the accessory 3 shaking or moving in the interface 10b and improving the plugging stability of the accessory 3. When the size of the accessory 3 along the second direction is small, only the second part 10d is used to store the accessory 3, and the fastener 11 can directly pass through the first part 10c to abut against the accessory 3. The first part 10c provides a moving space for the fastener 11, which is convenient for the abutting operation of the fastener 11. When the size of the accessory 3 along the second direction is large, the first part 10c and the second part 10d are used to store the accessory 3 together, and the fastener 11 can complete the abutment with the accessory 3 in the first part 10c. Through the abutting effect of the fastener 11, the different types of accessories 3 are limited and fixed, and the gap between the accessory 3 and the track 2 passing through the clamping space 10a is eliminated, so that the accessory 3 can be stored in the interface 10b while also being tightly fitted with the track 2. The working reliability of the clamp 1 is high.

[0065] It can be understood that the clamping space 10 has a clamping opening 10h on one side along the second direction and away from the interface 10b. The forming method of the clamping opening 10h is not limited. For example, see Figure 1 The clamping body 10 includes a first clamp 101 and a second clamp 102 along the third direction. The first clamp 101 and the second clamp 102 jointly define a clamping opening 10h and a clamping space 10. When the track 2 passes through the clamping space 10a along the first direction, the first clamp 101 and the second clamp 102 can limit the track 2 and reduce the probability of the track 2 slipping out of the clamping opening 10h.

[0066] Exemplarily, the first clamp 101 and the second clamp 102 are always in a relatively fixed state, that is, there is no relative movement between them.

[0067] The first clip 101 and the second clip 102 may be split, that is, the first clip 101 and the second clip 102 are separated, or the first clip 101 and the second clip 102 may be integrated.

[0068] The attachment 3 and the interface 10b may be connected in any manner.

[0069] For some examples, see Figure 5 When the size of the clamped accessory 3 along the second direction is smaller than the size of the second part 10d in the second direction, the clamped accessory 3 is in line contact with the inner surface of the first end of the second part 10d. It can be understood that in the plane projection perpendicular to the third direction, the clamped accessory 3 and the first end of the second part 10d can be understood as a point contact in mechanics, and the point contact extends along the third direction to generate the above-mentioned line contact.

[0070] In this embodiment, the accessory 3 is in line contact with the inner surface of the first end of the second part 10d when stored in the interface 10b. On the one hand, the accessory 3 can be stably fixed in the interface 10b, and the inner surface of the first end of the second part 10d can provide sufficient abutting support for the interface 10b, thereby reducing the probability of the accessory 3 becoming loose or shifting in the interface 10b. On the other hand, it can also reduce the restrictions on the accessory 3. Accessories 3 of different shapes and sizes can be stably accommodated in the second part 10d as long as the size along the second direction is smaller than the size on the second part 10d.

[0071] For some examples, see Figure 7 When the size of the clamped accessory 3 along the second direction is larger than the size of the second part 10d in the second direction, the clamped accessory 3 is in line contact with the inner surface of the first part 10c. It can be understood that in the plane projection perpendicular to the third direction, the clamped accessory 3 and the inner surface of the first part 10c can be understood as a point contact in mechanics, and the point contact extends along the third direction to generate the above-mentioned line contact.

[0072] In this embodiment, the accessory 3 is in line contact with the inner surface of the first part 10c when stored in the interface 10b. On the one hand, the accessory 3 can be stably fixed in the interface 10b, and the inner surface of the first part 10c can provide sufficient abutting support for the interface 10b, thereby reducing the probability of the accessory 3 becoming loose or shifting in the interface 10b. On the other hand, it can also reduce the restrictions on the accessory 3, and accessories 3 of different shapes and sizes can be stably accommodated in the interface 10b.

[0073] The shape of the inner surface of the first portion 10c is not limited, and may be an arc shape, a straight line shape, or a combination of an arc shape and a straight line shape.

[0074] For example, in some embodiments, see Figures 1 to 7At least a portion of the inner surface of the first portion 10c is arc-shaped. When the size of the clamped accessory 3 along the second direction is larger than the size of the second portion 10d in the second direction, the clamped accessory 3 abuts against the arc-shaped inner surface of the first portion 10c.

[0075] In this embodiment, the accessory 3 abuts against the arc-shaped inner surface, which can reduce the friction resistance when the accessory 3 abuts against the inner surface of the first part 10c, facilitates the smooth abutment between the accessory 3 and the inner surface of the first part 10c, and increases the working reliability of the clamp 1. In addition, when the clamped accessory 3 is an accessory 3 with a round rod or an accessory 3 with an elliptical rod, it can be in close contact with the arc-shaped inner surface of the first part 10c, thereby increasing the insertion stability of the accessory 3 in the interface 10b.

[0076] It should be noted that at least a portion of the inner surface of the first part 10c is arc-shaped. The inner surface of the first part 10c may be entirely arc-shaped, or the inner surface of the first part 10c may be a combination of arcs and other shapes. For example, the inner surface of the first part 10c may be a combination of arcs and straight lines.

[0077] In some other embodiments, please refer to Figures 1 to 7 A protrusion 10f is formed at the connection between the arc-shaped inner surface and the second part 10d. When the size of the clamped accessory 3 along the second direction is larger than the size of the second part 10d in the second direction, the clamped accessory 3 abuts against the protrusion 10f.

[0078] In this embodiment, the accessory 3 abuts against the connection between the first part 10c and the second part 10d. The first part 10c and the second part 10d can jointly provide abutment support for the accessory 3, thereby increasing the storage stability of the accessory 3 in the interface 10b.

[0079] The shapes of the first portion 10c and the second portion 10d are not limited.

[0080] For some examples, see Figures 1 to 4 The first part 10c is a part of a circle or an ellipse, the second part 10d is a part of a rectangle, the second part 10d is used to plug in the accessory 3 with a rectangular rod, and the first part 10c and the second part 10d are used to plug in the accessory 3 with a circular rod or an elliptical rod.

[0081] That is to say, when it is necessary to store an accessory 3 with a rectangular rod, the accessory 3 with a rectangular rod can be directly plugged into the second part 10d. At this time, only the second part 10d provides a plug-in space, and the first part 10c is vacant, so that the fastener 11 can enter the second part 10d through the first part 10c and abut against the accessory 3 with the rectangular rod, and eliminate the gap between the accessory 3 with the rectangular rod and the track 2, so that the accessory 3 with the rectangular rod can be stably stored in the interface 10b; when it is necessary to store an accessory 3 with a round rod or an elliptical rod, the first part 10c and the second part 10d jointly provide a plug-in space, and the fastener 11 enters the first part 10c through the connecting hole 10e and abuts against the accessory 3 with the round rod or the elliptical rod, and eliminates the gap between the accessory 3 with the round rod or the elliptical rod and the track 2, so that the accessory 3 with the round rod or the elliptical rod can be stably stored in the interface 10b.

[0082] For some examples, see Figure 4 The first portion 10c is a portion of a circle, the second portion 10d is a portion of a rectangle, and the diameter D1 of the circle is greater than the width W1 of the short side corresponding to the second portion 10d, that is, D1>W1.

[0083] That is to say, in this embodiment, the second part 10d accommodates the accessory 3 with a rectangular rod, and the first part 10c and the second part 10d jointly accommodate the accessory 3 with a round rod. The size of the accessory 3 with the rectangular rod along the second direction is smaller than the width of the short side corresponding to the second part 10d, and the size of the accessory 3 with the round rod along the second direction is larger than the width of the short side corresponding to the second part 10d. The accessory 3 with the round rod is accommodated in the first part 10c and the second part 10d. The first part 10c and the second part 10d have sufficient space to accommodate the accessory 3 with the round rod, and the fastener 11 can also extend into the first part 10c a sufficient distance so that the accessory 3 with the round rod can fit tightly with the track 2.

[0084] In some other embodiments, the first portion 10c is a portion of an ellipse, the second portion 10d is a portion of a rectangle, and the dimension of the ellipse in the short axis direction is greater than the width W1 of the short side corresponding to the second portion 10d.

[0085] That is to say, in this embodiment, the second part 10d accommodates the rectangular accessory 3, the first part 10c and the second part 10d jointly accommodate the elliptical rod accessory 3, the size of the rectangular rod accessory 3 along the second direction is smaller than the width of the short side corresponding to the second part 10d, the size of the elliptical rod accessory 3 along the second direction is larger than the width of the short side corresponding to the second part 10d, the elliptical rod accessory 3 is accommodated in the first part 10c and the second part 10d, the first part 10c and the second part 10d have enough space to accommodate the accessory 3, and the fastener 11 can also extend into the first part 10c a sufficient distance so that the elliptical rod accessory 3 can fit tightly with the track 2.

[0086] For some examples, see Figures 5 to 7 The first part 10c and the second part 10d are used to accommodate round rods of different diameters, and the second part 10d is used to accommodate rectangular rods of different widths, wherein the diameter of the round rod with the smallest diameter is greater than the width of the rectangular rod with the largest width. In this way, when the rectangular rod is inserted into the interface 10b, it can be directly accommodated in the second part 10d and will not exceed the second part 10d to enter the first part 10c. When the round rod is inserted into the interface 10b, it can be accommodated by the first part 10c and the second part 10d, and under the action of the fastener 11, it abuts against the inner surface of the first part 10c and the track 2.

[0087] The width direction of the rectangular rod is along the second direction, that is, the width direction of the rectangular rod is consistent with the extension direction of the short side of the second part 10d, so that the rectangular rod can be inserted into the second part 10d more smoothly and abut against the inner surface of the second part 10d.

[0088] In some embodiments, the fastener 11, the track 2 passing through the clamping space 10a, and the side wall of the interface 10b are used to form three mechanical support points for the circular rod or the elliptical rod passing through the first part 10c and the second part 10d.

[0089] For example, see Figure 7 The support point formed by the track 2 on the circular rod is A1, the support point formed by the first part 10c on the circular rod is A2, and the support point formed by the fastener 11 on the circular rod is A3. A1, A2, and A3 together constitute three mechanical support points for the circular rod.

[0090] In this embodiment, the fastener 11, the track 2 passing through the clamping space 10a, and the side wall of the interface 10b jointly provide abutment support for the round rod or the elliptical rod, while eliminating the gap between the round rod or the elliptical rod and the track 2, and also increasing the stability of the round rod or the elliptical rod in the interface 10b.

[0091] In some embodiments, a line connecting any two of the three mechanical support points does not pass through the center of the circular rod or the elliptical rod passing through the first part 10c and the second part 10d.

[0092] For example, see Figure 7 The accessory 3 passing through the first part 10c and the second part 10d is a circular rod, the line connecting the support point A1 formed by the track 2 on the circular rod and the support point A2 formed by the first part 10c on the circular rod does not pass through the center R1 of the circular rod, the line connecting the support point A2 formed by the first part 10c on the circular rod and the support point A3 formed by the fastener 11 on the circular rod does not pass through the center R1 of the circular rod, and the line connecting the support point A1 formed by the track 2 on the circular rod and the support point A3 formed by the fastener 11 on the circular rod does not pass through the center R1 of the circular rod.

[0093] It can be understood that if the line connecting two of the three mechanical support points passes through the center of the circular rod attachment or the elliptical rod attachment passing through the first part and the second part, the forces acting on the circular rod attachment or the elliptical rod attachment at these two points will offset each other, and the other point will still retain the force on the circular rod attachment or the elliptical rod attachment, thereby affecting the force stability of the circular rod attachment or the elliptical rod attachment in the interface.

[0094] Therefore, in this embodiment, the line connecting any two of the three mechanical support points does not pass through the center of the round rod or the elliptical rod, which facilitates the mutual offset of the forces exerted on the round rod or the elliptical rod by the fastener 11, the track 2 passing through the clamping space 10a, and the inner surface of the first part 10c at the three mechanical support points, so that the force on the round rod or the elliptical rod in the interface 10b is stable, the plug-in stability is high, and the working reliability of the clamp 1 is strong.

[0095] In some embodiments, the three mechanical support points constitute three vertices of an acute triangle.

[0096] For example, see Figure 7 The angle between the line connecting the support point A1 formed by the track 2 on the circular rod and the support point A2 formed by the first part 10c on the circular rod and the line connecting the support point A2 formed by the first part 10c on the circular rod and the support point A3 formed by the fastener 11 on the circular rod is an acute angle, the angle between the line connecting the support point A1 formed by the track 2 on the circular rod and the support point A2 formed by the first part 10c on the circular rod and the line connecting the support point A1 formed by the track 2 on the circular rod and the support point A3 formed by the fastener 11 on the circular rod is an acute angle, and A1, A2, and A3 are connected in sequence to form an acute triangle.

[0097] In this embodiment, the points of action of the track 2 on the round rod accessory 3 or the elliptical rod accessory 3, the points of action of the first part 10c on the round rod accessory 3 or the elliptical rod accessory 3, and the points of action of the fastener 11 on the round rod accessory 3 or the elliptical rod accessory 3 are relatively evenly distributed on the round rod accessory 3 or the elliptical rod accessory 3, so that the force on the round rod accessory 3 or the elliptical rod accessory 3 is relatively uniform, which facilitates the mutual offset of the forces of the track 2, the first part 10c, and the fastener 11 on the round rod accessory 3 or the elliptical rod accessory 3, thereby improving the insertion stability of the round rod accessory 3 or the elliptical rod accessory 3 in the interface 10b.

[0098] In some embodiments, a dimension L1 of the first portion 10c on a straight line along a long side of a rectangle corresponding to the second portion 10d is not less than a diameter D1 of a circle corresponding to the first portion 10c, that is, L1≥D1.

[0099] In this way, when the diameter of the circular rod accessory 3 inserted in the interface 10b is matched with the diameter of the circle corresponding to the first part 10c, the circular rod accessory 3 can smoothly pass through the junction of the first part 10c and the second part 10d, abut against the track 2, and fit tightly with the track 2 under the action of the fastener 11, reducing the probability of the circular rod accessory 3 being stuck at the junction of the first part 10c and the second part 10d and unable to abut against the track 2, and the fastener 11 can also smoothly extend into the first part 10c.

[0100] In some embodiments, in a plane projection perpendicular to the second direction, the extension direction of the fastener 11 is tilted so that the force applied by the fastener 11 to the accessory 3 inserted through the interface 10b has at least a component along the first direction and a component along the second direction and toward the side where the interface 10b is located, wherein the first direction is perpendicular to the second direction.

[0101] The extension direction of the fastener 11 is at a certain angle to the first direction. The force of the fastener 11 can not only eliminate the gap between the accessory 3 and the track 2, but also offset the force of the track 2 and the inner surface of the interface 10b on the accessory 3. In this way, the accessory 3 can be more stably and reliably accommodated in the interface 10b.

[0102] When accessory 3 is only accommodated in the second part 10d, accessory 3 is fixed against fastener 11, the inner surface of the second part 10d and track 2. Track 2 applies a force on accessory 3 along the second direction and toward the side where interface 10b is located, which cancels out the force component applied by fastener 11 on accessory 3 along the second direction and toward the side where interface 10b is located. The second part 10d applies a force on accessory 3 along the first direction, which cancels out the force component applied by fastener 11 on accessory 3 along the first direction. In this way, the forces applied by fastener 11, the inner surface of second part 10d and track 2 on accessory 3 cancel out each other, and accessory 3 remains stable in the second part 10d.

[0103] When the accessory 3 is accommodated in the first part 10c and the second part 10d, the accessory 3 is fixed against the fastener 11, the inner surface of the first part 10c and the track 2. The track 2 applies a force to the accessory 3 along the second direction and toward the side where the interface 10b is located, which cancels out the component force applied by the fastener 11 to the accessory 3 along the second direction and toward the side where the interface 10b is located. The first part 10c applies a force to the accessory 3 along the first direction, which cancels out the component force applied by the fastener 11 to the accessory 3 along the first direction. In this way, the forces applied by the fastener 11, the inner surface of the first part 10c and the track 2 to the accessory 3 cancel out each other, and the accessory 3 remains stable in the first part 10c and the second part 10d.

[0104] For some examples, see Figure 7 The angle α between the extension direction of the fastener 11 and the first direction is 20° to 70°, for example, 20°, 25°, 30°, 32°, 37°, 40°, 46°, 50°, 53°, 60°, 61°, 64°, 70°, etc.

[0105] In this embodiment, the angle between the extension direction of the fastener 11 and the first direction is appropriate, so that the component forces generated by the fastener 11 on the accessory 3 along the first direction and the second direction can offset each other with the component forces of the inner surface of the interface 10b on the accessory 3 and the component forces of the track 2 on the accessory 3 respectively. At the same time, the probability of interference between the fastener 11 and the track 2 can be reduced, thereby improving the structural reliability of the clamp 1.

[0106] In some embodiments, the ends of the fastener 11 are used to abut against adjacent portions of two surfaces of a rectangular rod passing through the second portion 10 d .

[0107] It should be noted that the adjacent parts of the two surfaces of the rectangular rod can be a straight edge, in which case the end of the fastener 11 abuts against the straight edge, or can be a chamfered or rounded part, in which case the end of the fastener 11 abuts against the chamfered or rounded part.

[0108] In this embodiment, the ends of the fastener 11 are abutted against the adjacent parts of the two surfaces of the rectangular rod, so that the fastener 11 can apply a force to the rectangular rod from one of the four corners of the rectangular rod. When the fastener 11 eliminates the gap between the fastener 11 and the track 2 by rotating, the fastener 11 and the rectangular rod are not easy to slide, thereby increasing the abutment stability between the fastener 11 and the rectangular rod.

[0109] In some embodiments, the top side surface 10i of the first end of the second portion 10d forms a curved surface or a slope 10g at the end surface, and the curved surface or the slope 10g extends from close to the top side surface 10i toward a direction away from the top side surface 10i, so that the size of the second portion 10a along the first direction tends to gradually increase, wherein the top side surface 10i refers to the side of the second portion 10d close to the first portion 10c.

[0110] For example, see Figure 4 and Figure 5 The top side surface and the end surface of the first end of the second part 10d are formed into an inclined surface 10g.

[0111] In this embodiment, the setting of the curved surface or inclined surface 10g facilitates the abutment between the rectangular rod and the inner surface of the second part 10d. The curved surface or inclined surface 10g can provide sufficient abutment support for the rectangular rod. When the rectangular rod abuts on the curved surface or inclined surface 10g, the curved surface or inclined surface 10g can provide support for the rectangular rod along the first direction while also providing support for the rectangular rod along the second direction, thereby improving the insertion stability of the rectangular rod in the second part 10d.

[0112] The clamping body 10 may be formed in any manner.

[0113] In some embodiments, the clamping body 10 is an integrated structure with fast molding speed and high production efficiency. The clamping body 10 and the fastener 11 are assembled to obtain the clamp 1 to penetrate the track 2 and accommodate the accessories 3.

[0114] Of course, in other embodiments, the clamping body 10 may also be a split structure, which is not limited here.

[0115] The diameter of the circular rod that the first portion 10c and the second portion 10d accommodate together is not limited.

[0116] For example, in some embodiments, the first portion 10c and the second portion 10d are used to accommodate a round rod with a diameter of 13 mm (millimeter) to 25 mm. For example, the diameter of the round rod can be 13 mm, 14 mm, 15 mm, 16 mm, 17 mm, 18 mm, 19 mm, 20 mm, 21 mm, 22 mm, 23 mm, 24 mm, 25 mm, etc.

[0117] In this embodiment, the diameter of the circular rod is neither too large nor too small. While being able to be accommodated in the first part 10c and the second part 10d, the fastener 11, the inner surface of the first part 10c, and the track 2 can support the circular rod more stably. In addition, the size requirement of the docking interface 10b can be reduced, making the structure of the clamp 1 simple and compact.

[0118] Although the embodiment of the present application is described by taking a round rod as an example, the first part 10c and the second part 10d can also jointly accommodate a rectangular rod of appropriate size.

[0119] The width of the rectangular rod received by the second portion 10d is not limited.

[0120] In some embodiments, the second portion 10d is used to accommodate a rectangular rod with a width of 4 mm to 12 mm. For example, the width of the rectangular rod can be 4 mm, 5 mm, 6 mm, 7 mm, 8 mm, 9 mm, 10 mm, 11 mm, 12 mm, etc.

[0121] In this embodiment, the width of the rectangular rod is appropriate, and while being able to be accommodated in the second part 10d, the fastener 11, the inner surface of the second part 10d, and the track 2 can support the rectangular rod more stably. In addition, the size requirements for the second part 10d can also be reduced, thereby making the structure of the clamp 1 simpler and more compact.
