DETAILED DESCRIPTION

[0027] The embodiments of the present invention are described in detail below, and examples of the embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals throughout represent the same or similar elements or elements having the same or similar functions. The embodiments described below with reference to the accompanying drawings are exemplary and are intended to be used to explain the present invention, and should not be construed as limiting the present invention.

[0028] like Figures 1 to 4 As shown, an upper clamping assembly of the utility model comprises an upper clamping body 1, a first upper clamping jaw 2, a second upper clamping jaw 3 and an upper clamping spring 4; one end of the first upper clamping jaw 2 is rotatably arranged on the upper clamping body 1, and the other end of the first upper clamping jaw 2 is provided with a first upper clamping groove 21; the second upper clamping jaw 3 is arranged opposite to the first upper clamping jaw 2, one end of the second upper clamping jaw 3 is rotatably arranged on the upper clamping body 1, and the other end of the second upper clamping jaw 3 is provided with a second upper clamping groove 31, and a clamping groove is formed between the second upper clamping groove 31 and the first upper clamping groove 21; one end of the upper clamping spring 4 is connected to the first upper clamping jaw 2, and the other end of the upper clamping spring 4 is connected to the second upper clamping jaw 3, so that the second upper clamping groove 31 and the first upper clamping groove 21 have a tendency to approach each other.

[0029] In this way, the upper clamping assembly involved in the utility model, when in use, places the buckle body 10 in the clamping groove, so that the first upper clamping groove 21 is located on one side of the buckle body 10, and the second upper clamping groove 31 is located on the other side of the buckle body 10. Under the action of the upper clamping spring 4, the first upper clamping groove 21 is pressed against one side of the buckle body 10, and the second upper clamping groove 31 is pressed against the other side of the buckle body 10, thereby clamping the buckle body 10, thereby stably restricting the buckle body 10, and facilitating the connection between the buckle surface and the fabric and the buckle body 10.

[0030] Optionally, a pressing plane 11 is formed at the bottom of the upper clamp body 1. By setting the pressing plane 11, when the buckle surface and the fabric are connected to the buckle body 10, the upper clamp body 1 moves downward so that the pressing plane 11 presses on the fabric, thereby making the fabric less likely to wrinkle. A buffer elastic pad is provided on the pressing plane 11, and the buffer elastic pad protrudes from the pressing plane 11. When the pressing plane 11 is pressed downward to press the fabric, the buffer elastic pad is compressed, and the buffer elastic pad plays a buffering role to reduce the impact force of the pressing plane 11 on the fabric.

[0031] Furthermore, an input port 12 is provided on the upper clamp body 1, and the input port 12 is directly opposite to the clamping groove. By providing the input port 12, the buckle body 10 can be pushed from the input port 12 into the clamping groove to achieve clamping of the buckle body 10.

[0032] In this embodiment, the upper clamp body 1 includes a front frame body 13 and a rear frame body 14, a first installation cavity 15 for installing the first upper clamping jaw 2 is formed between the front frame body 13 and the rear frame body 14, and a second installation cavity 16 for installing the second upper clamping jaw 3 is also formed between the front frame body 13 and the rear frame body 14. During assembly, the first upper clamping jaw 2 is placed in the first installation cavity 15, and the first installation cavity 15 plays a role in limiting the first upper clamping jaw 2, and the second upper clamping jaw 3 is placed in the second installation cavity 16, and the second installation cavity 16 plays a role in limiting the second upper clamping jaw 3.

[0033] Specifically, a first front connection hole 131 is provided on the front frame body 13, a first rear connection hole 141 is provided on the rear frame body 14, and a first through hole 22 is provided on the first upper clamping jaw 2. The first through hole 22, the first rear connection hole 141 and the first front connection hole 131 are located in the same straight line. After the first upper clamping jaw 2 is placed in the first installation cavity 15, a connecting pin can be used to pass through the first front connection hole 131, the first through hole 22 and the first rear connection hole 141 in sequence, so that the first upper clamping jaw 2 can be rotatably arranged on the upper clamping body 1.

[0034] Specifically, the front frame body 13 is provided with a second front connection hole 132, the rear frame body 14 is provided with a second rear connection hole 142, and the second upper clamping jaw 3 is provided with a second through hole 32, and the second through hole 32, the second rear connection hole 142 and the second front connection hole 132 are located in the same straight line. After the second upper clamping jaw 3 is placed in the second installation cavity 16, a connecting pin can be used to sequentially pass through the second front connection hole 132, the second through hole 32 and the second rear connection hole 142, so that the second upper clamping jaw 3 can be rotatably arranged on the upper clamping body 1.

[0035] In this embodiment, a first guide surface 23 is provided at the end of the first upper clamping jaw 2, and the first guide surface 23 is located at the input end of the first upper clamping groove 21. When the buckle body 10 is placed in the first upper clamping groove 21, the buckle body 10 moves along the first guide surface 23 and enters the first upper clamping groove 21, so that the buckle body 10 is placed in the first upper clamping groove 21.

[0036] In this embodiment, a second guide surface 33 is provided at the end of the second upper clamping jaw 3, and the second guide surface 33 is located at the input end of the second upper clamping groove 31. The second guide surface 33 and the first guide surface 23 are distributed in an eight-shaped shape. When the buckle body 10 is placed in the second upper clamping groove 31, the buckle body 10 moves along the second guide surface 33 and enters the second upper clamping groove 31, so that the buckle body 10 is placed in the second upper clamping groove 31. In this way, one side of the buckle body 10 is clamped by the first upper clamping groove 21, and the other side of the buckle body 10 is clamped by the second upper clamping groove 31, so as to stably restrict the buckle body 10 and facilitate the connection of the buckle surface and the fabric with the buckle body 10.

[0037] Furthermore, a first slot 24 for inserting one end of the upper clamping spring 4 is provided on the outer side of the first upper clamping jaw 2, and a second slot 34 for inserting the other end of the upper clamping spring 4 is provided on the outer side of the second upper clamping jaw 3. By providing the first slot 24 and the second slot 34, during assembly, one end of the upper clamping spring 4 can be inserted into the first slot 24, and the other end of the upper clamping spring 4 can be inserted into the second slot 34. Under the action of the upper clamping spring 4, the second upper clamping groove 31 and the first upper clamping groove 21 have a tendency to approach each other.

[0038] In this embodiment, a spring buckle 5 is further included, and a limit opening 51 for limiting the upper clamping spring 4 is formed in the spring buckle 5. The spring buckle 5 is arranged on the upper clamping body 1. The spring buckle 5 can be fixed to the upper clamping body 1 by screws, thereby limiting the upper clamping spring 4 and preventing the upper clamping spring 4 from detaching from the upper clamping body 1.

[0039] The above embodiments and drawings do not limit the product form and style of the present utility model. Any appropriate changes or modifications made by ordinary technicians in the relevant technical field should be deemed to be within the patent scope of the present utility model.
