[0028] like Figures 2-3 As shown, the first hook 3 includes a first support portion 13 , on which a first bending portion 14 and a second bending portion 15 are provided. The first support portion 13 , the first bending portion 14 and the second bending portion 15 are integrally formed.

[0029] The end of the first support portion 13 closest to the second hook 4 is connected to the second bend portion 15, and the end of the first support portion 13 away from the second hook 4 is connected to the first bend portion 14. There is a certain distance between the first bend portion 14 and the first bend portion 14, and the first bend portion 14 and the second bend portion 15 have the same bending direction. The second hook 4 includes a second support portion 16, and the second support portion 16 and the first support portion 13 extend in opposite directions. The second support portion 16 is connected to a third bend portion and a fourth bend portion. The end of the second support portion 16 closest to the first hook 3 is connected to the third bend portion, and the end of the second support portion 16 away from the first hook 3 is connected to the fourth bend portion. There is a certain distance between the third bend portion and the fourth bend portion, and the third bend portion and the fourth bend portion have the same bending direction.

[0030] The first bend 14 is adapted to the third bend 17, and the second bend 15 is adapted to the fourth bend 18. The first bend 14 and the third bend 17 are fastened together to form a first set of fastenings, while the second bend 15 and the fourth bend 18 are fastened together to form a second set of fastenings. Together, the first and second sets of fastenings complete the fastening of the first hook 3 and the second hook 4.

[0031] After the first hook 3 and the second hook 4 are fastened together, a plurality of openings 5 ​​are formed between the first swing arm 1 and the second swing arm 2, and all the openings 5 ​​are circular in shape. The sizes of the different circular openings 5 ​​can be the same or different. The size of the circular openings 5 ​​is adapted to the size of the pipe, and a plurality of different circular openings 5 ​​can be provided for the passage of a plurality of pipes of different sizes, thereby achieving one-time assembly of pipes of multiple different sizes. After the first hook 3 and the second hook 4 are fastened together, a partition structure 19 is further formed between the first swing arm 1 and the second swing arm 2, and the partition structure 19 separates the plurality of openings 5 ​​formed between the first swing arm 1 and the second swing arm 2. As an example, after the first hook 3 and the second hook 4 are fastened together, two openings 5 ​​are formed between the first swing arm 1 and the second swing arm 2, and the two openings 5 ​​have different sizes for the passage of two different pipes.

[0032] A clamp device of this embodiment includes a first swing arm 1 and a second swing arm 2. A first hook 3 is provided at the end of the first swing arm 1, and a second hook 4 is provided at the end of the second swing arm 2. The first hook 3 and the second hook 4 are adapted to each other.

The clamp device provided by the utility model can fix pipes of multiple different sizes at one time through simple fastening. It not only solves the problem that fixing pipes in the prior art requires multiple clamps of different structures to be fastened and connected, which is complicated to install, but also reduces the types of clamp structures and the number of molds, greatly reducing the production and assembly costs of the clamps.

[0033] Example 2

[0034] like Figure 1 As shown, this embodiment provides a clamp device, including a first swing arm 1 and a second swing arm 2, wherein a first hook 3 is provided at the end of the first swing arm 1, and a second hook 4 is provided at the end of the second swing arm 2, and the first hook 3 and the second hook 4 are adapted to each other; after the first hook 3 and the second hook 4 are buckled together, a plurality of openings 5 ​​are formed between the first swing arm 1 and the second swing arm 2, and the plurality of openings 5 ​​are used for allowing pipes of different sizes to pass through.

[0035] The clamp device further includes a first thin arm 6 , a first end of the first thin arm 6 is connected to the first swing arm 1 , and a second end of the first thin arm is connected to the second swing arm 2 .

[0036] The first thin arm 6 is capable of rotating, and is used to drive the second swing arm 2 to rotate.

[0037] The connection between the first swing arm 1 and the second swing arm 2 forms a first thin arm 6 after once or twice thinning, and the thickness of the first thin arm 6 is smaller than that of the first swing arm 1 and the second swing arm 2. The first thin arm 6 extends from the middle to both sides, and the thickness gradually increases until the two sides of the first thin arm 6 are connected with the first swing arm 1 and the second swing arm 2. The first thin arm 6 is made of polypropylene material, and because the polypropylene material has the characteristics of repeated bending, the first thin arm 6 formed after thinning has a certain elasticity, which can more easily realize bending and rotation. In the case of keeping the first swing arm 1 stationary, the rotation of the first thin arm 6 drives the second hook 4 at the end of the second swing arm 2 to move towards the first hook 3 at the end of the first swing arm 1, and the second hook 4 is buckled with the first hook 3.

[0038] As shown in Figure 2 Preferably, the first swing arm 1 includes a first circular arc and a second circular arc, and the second swing arm 2 includes a third circular arc and a fourth circular arc, and the first circular arc is arranged opposite to the third circular arc, and the second circular arc is arranged opposite to the fourth circular arc. As shown in Figures 3-4 When the first hook 3 and the second hook 4 are buckled, the first circular arc and the third circular arc form a first opening, and the first end of the first circular arc and the first end of the third circular arc form a first gap 20, and the first gap 20 is arranged at a position close to the buckling position of the first hook 3 and the second hook 4. The second end of the first circular arc and the second end of the third circular arc form a second gap 21, and the width of the first gap 20 is greater than the width of the second gap 21.

[0039] The second circular arc and the fourth circular arc form a second opening, and the shapes of the first opening and the second opening are both circular, and the size of the first opening is greater than that of the second opening. The first end of the second circular arc and the first end of the fourth circular arc form a third gap 22, and the second end of the second circular arc and the second end of the fourth circular arc form a fourth gap 23, and the fourth gap 23 is arranged at a position close to the first thin arm 6, and the width of the fourth gap 23 is greater than that of the third gap 22, and the third gap 22 is in communication with the second gap 21.

[0040] The clamp device of this embodiment further includes a first thin arm 6, the first end of which is connected to the first swing arm 1, and the second end of which is connected to the second swing arm 2. The first thin arm 6 is rotatable and is used to drive the second swing arm 2 to rotate. The connection between the first and second swing arms 1 and 2 is thinned to form the first thin arm 6. The first thin arm 6 has a certain degree of elasticity. The first thin arm 6 can drive the second swing arm 2 to rotate toward the first swing arm 1, thereby driving the second hook 4 at the end of the second swing arm 2 toward the first hook 3 at the end of the first swing arm 1. After the second hook 4 approaches the first hook 3 and engages with the first hook 3, multiple openings 5 ​​are formed between the second and first swing arms 2 and 1, allowing pipes of different sizes to pass through. The rotation of the first thin arm 6 allows the second swing arm 2 to rotate flexibly in a clockwise or counterclockwise direction, simplifying the connection between the second and first swing arms 2 and 1. This not only enables the clamp device to secure pipes of various sizes, but also significantly reduces the production cost of the clamp device.

[0041] Example 3

[0047] The third and fourth clamping hooks 8 and 9 are opposite in extension direction and have the same shape, and the shape of the third and fourth clamping hooks 8 and 9 is J-shaped. The bottom of the third clamping hook 8 extends into the lower part of the fourth clamping hook 9, so that the third clamping hook 8 exerts an upward force on the fourth clamping hook 9, and the fourth clamping hook 9 exerts a downward force on the third clamping hook 8. Under the joint action of the two forces, the third and fourth clamping hooks 8 and 9 are in force balance, and the clamping of the third and fourth clamping hooks 8 and 9 is completed.

[0048] The connection between the second swing arm 2 and the third swing arm 7 is subjected to one or two thinning treatments to form a second thin arm 10, which serves to connect the second swing arm 2 and the third swing arm 7. The second thin arm 10 is made of polypropylene material and has a certain elasticity. The second thin arm 10 extends from the middle to both sides and gradually increases in thickness.

[0049] The second thin arm 10 can rotate clockwise or counterclockwise. Rotating the second thin arm 10 makes the third swing arm 7 rotate towards the second swing arm 2, and in this process, the third clamping hook 8 gradually approaches the fourth clamping hook 9 until the third and fourth clamping hooks 8 and 9 are clamped.

[0050] After the third and fourth clamping hooks 8 and 9 are clamped, third and fourth openings are formed. The sizes of the third and fourth openings can be the same or different, and the sizes of the third and fourth openings are smaller than the first opening. When the sizes of the third and fourth openings are different, they can be used to pass through pipes of different sizes.

[0051] The third and fourth openings are both non-closed circles, and the non-closed positions of the third and fourth openings are provided with transition surfaces, and the shape of the transition surface is rectangular. The transition surface can better clamp the pipe into the third and fourth openings, and the transition surface cooperates with the arc surface of the third and fourth openings to fix the pipe.

[0052] When four openings 5 are needed to be formed to fix four pipes of different sizes, first rotate the first thin arm 6 counterclockwise to drive the second swing arm 2 to rotate counterclockwise, so that the second clamping hook 4 approaches the first clamping hook 3, and the first and second clamping hooks 3 and 4 are clamped to form the first and second openings. Then rotate the second thin arm 10 counterclockwise to drive the third swing arm 7 to rotate counterclockwise, so that the third clamping hook 8 approaches the fourth clamping hook 9, and the third and fourth clamping hooks 8 and 9 are clamped to form the third and fourth openings.

[0053] The clamp device of this embodiment also includes a third swing arm 7, which is connected to the second swing arm 2. A third hook 8 is provided at the end of the third swing arm 7, and a fourth hook 9 is provided on the second swing arm 2 near the third hook 8, and the fourth hook 9 is adapted to the third hook 8. When the third hook 8 and the fourth hook 9 are engaged, a plurality of openings 5 ​​are formed between the second swing arm 2 and the third swing arm 7. The clamp device also includes a second thin arm 10, a first end of which is connected to the second swing arm 2, and a second end of which is connected to the third swing arm 7. The second thin arm 10 is rotatable, and the second thin arm 10 drives the third swing arm 7 to rotate. Rotating the second thin arm 10 counterclockwise drives the third swing arm 7 to rotate counterclockwise, causing the third hook 8 to approach the fourth hook 9, engaging the third hook 8 with the fourth hook 9, and forming the third and fourth openings.
