[0002] During garment production, in order to make the garment more exquisite, it is often necessary to embroider the garment. During the embroidery process, an embroidery machine is required, and a clip made of steel sheets is used on the embroidery machine to clamp the cloth.

[0003] There are still some problems with the existing cloth-clamping steel sheets on embroidery machines. First, the cloth-clamping operation of the current cloth-clamping steel sheets is relatively troublesome and labor-intensive, resulting in low cloth-clamping efficiency. Second, the current cloth-clamping steel sheets do not clamp the cloth tightly, and the cloth is easy to fall off. Therefore, a clamp-type air clamp is needed to solve the above problems. Utility Model Content

[0006] Preferably, the expansion and contraction of the airbag is controlled by a solenoid valve.

[0007] Preferably, the first hinge, the shaft, the second hinge and the limit block are all made of metal materials, and the airbag is made of polymer material and can expand and contract.

[0008] The pliers-type air clamp provided by the utility model can not only clamp the cloth, but also the cloth clamping operation is relatively simple, which reduces the labor intensity, improves the cloth clamping efficiency, further improves the clamping effect of the cloth and has strong adaptability, does not damage any cloth, is simple to operate, and is highly practical. BRIEF DESCRIPTION OF THE DRAWINGS

[0009] Figure 1 This is a schematic diagram of a clamp-type air clamp.

[0010] In the attached drawings: 1-first hinge, 2-axis rod, 3-second hinge, 4-limiting block, 5-airbag. DETAILED DESCRIPTION

[0011] In order to make the purpose, technical solution and advantages of the utility model more clear, the utility model is further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described here are only used to explain the utility model, and do not limit the utility model.

[0012] The specific implementation of the present utility model is described in detail below in conjunction with specific embodiments.

[0013] See also Figure 1 The utility model provides a clamp-type air clamp, which comprises:

[0014] A first hinge 1, wherein the first hinge 1 is provided with a first through hole, a shaft rod 2 passes through the first through hole provided by the first hinge 1, and external threads are provided at both ends of the shaft rod 2; a second hinge 3, which is arranged in cooperation with the first hinge 1, and the second hinge 3 is provided with a groove and a second through hole, and the second through hole is provided on both sides of the groove, and the second hinge 3 can be inserted into the first hinge 1 through the groove and the second through hole is aligned with the first through hole, and the shaft rod 2 passes through the second through hole; a limit block 4, which is threadedly connected to both ends of the shaft rod 2, and is used to limit the shaft rod 2 to prevent the shaft rod 2 from separating from the first hinge 1 and the second hinge 3; an airbag 5, which is adhered between the first hinge 1 and the second hinge 3, and the airbag 5 can be inflated to push the first hinge 1 and the second hinge 3 to rotate on the shaft rod 2, and is used to push the first hinge 1 and the second hinge 3 to clamp the fabric.

[0015] like Figure 1 As shown, as a preferred embodiment of the present utility model, the expansion and contraction of the airbag 5 is controlled by a solenoid valve.

[0016] When using the clamp-type air clamp, the clamp-type air clamp is installed on the embroidery machine, and the clamp-type air clamp is driven to move by the embroidery machine. When clamping cloth, the airbag 5 is controlled to expand by the electromagnetic valve. The expansion of the airbag 5 pushes the first hinge 1 and the second hinge 3 to rotate on the shaft 2. The first hinge 1 and the second hinge 3 can clamp the cloth, and then the movement of the air clamp can be controlled by the embroidery machine. When releasing the cloth, it is only necessary to open the electromagnetic valve in the reverse direction to reset the airbag 5. The airbag 5 can drive the first hinge 1 and the second hinge 3 to rotate in the reverse direction and reset, thereby releasing the cloth.

[0017] like Figure 1 As shown, as a preferred embodiment of the utility model, the first hinge 1, the shaft 2, the second hinge 3 and the limit block 4 are all made of metal materials, and the airbag 5 is made of polymer material and can expand and contract.

[0018] The first hinge 1, the shaft 2, the second hinge 3 and the limit block 4 are made of metal materials to ensure their hardness, so that the first hinge 1 and the second hinge 3 can smoothly rotate on the shaft 2 and clamp the fabric. The bag 5 is made of polymer material to ensure that it can expand and contract smoothly.

[0019] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions and improvements made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
