[0022] As can be seen from the above, before the edge taping machine is used to process the mattress, the pusher 2 drives the driving device to move toward the mattress, so that the first clamping assembly 5 and the second clamping assembly 6 on the driving device are close to the side of the mattress, that is, close to the corner between the fabric and the side of the mattress. Driven by the driving device, the first clamping assembly 5 and the second clamping assembly 6 clamp the fabric and the side of the mattress, so that the side and fabric of the mattress can be sewn by the edge taping machine, which reduces the need to clamp the fabric and the side of the mattress manually.

[0023] In actual use, the pushing device 2 is a cylinder or an electric push rod.

[0024] In some embodiments, the driving device is a pneumatic clamp 41, and the pneumatic clamp 41 has two swing arms, and the first clamping assembly 5 and the second clamping assembly 6 are respectively arranged on the swing arms in a one-to-one correspondence. The driving device is used to drive the first clamping assembly 5 and the second clamping assembly 6 to move toward each other or away from each other, so that the first clamping assembly 5 and the second clamping assembly 6 can clamp or loosen the fabric and side circumference of the mattress. The driving device is a pneumatic clamp 41, which is easy to use. Since the pneumatic clamp 41 is a product in the prior art and can be purchased on the market, the pneumatic clamp 41 will not be described in detail. The pneumatic clamp 41 drives the first clamping assembly 5 and the second clamping assembly 6 to swing, so that the first clamping assembly 5 and the second clamping assembly 6 clamp the fabric and side circumference of the mattress.

[0025] In some embodiments, in order to facilitate the processing of the mattress fabric and the side circumference, the two swing arms of the pneumatic clamp 41 are arranged in mirror images, and an angle is formed between the two swing arms of the pneumatic clamp 41, and the angle formed by the two swing arms is inclined downward. The two swing arms on the pneumatic clamp 41 are used to drive the first clamping assembly 5 and the second clamping assembly 6 to swing. This structure is simple and easy to set up.
