Abstract

The invention discloses a clamping device for a sewing machine. The clamping device comprises a clamping groove, wherein a screw hole is formed in the clamping groove, and a clamping plate is arranged on the clamping groove; a semicircular notch is formed in the clamping plate, and a connecting bolt respectively penetrates through the screw hole and the notch and is connected with a screw cap. The clamping device for the sewing machine provided by the invention has the advantages that the contact area between the clamping groove and the clamping plate is relatively large, so that the clamping damage to the clamping device can be effectively reduced, the operation and use are convenient, and the practicality is strong.

Description

technical field [0001] The invention relates to a sewing machine, in particular to a sewing machine clamping device. Background technique [0002] In modern industrial production, the sewing machine is an important tool for garment production, and the clamping device of the sewing machine is an important part of the sewing machine. Usually, the clamping device of the sewing machine consists of a connecting bolt, a clamping plate and a clamping groove. However, due to the small area of ​​the clamping device, the clamping device will inevitably produce clamping marks after a long time, and even cause the sewing machine not to work normally when it is serious. Contents of the invention [0003] The present invention mainly solves the technical problems existing in the prior art, thereby providing a sewing machine clamping device. [0004] Above-mentioned technical problem of the present invention is mainly solved by following technical scheme: [0005] A sewing machine cla...
