The clamping plate is provided with corresponding outer hook plates and inner hook plates at both ends, and the ends of the clamping plate are connected to the corresponding inner hook plates. The lower end of the outer hook plate includes at least one inwardly folded section. The folded section is detachably connected to the outer wall of the inner hook plate.

[0006] As a further improvement of the present invention, the outer hook plate includes a first bent plate and a connecting section. The first bent plate extends toward the clamping plate and has an end that is folded inward. The upper end of the connecting section is connected to the outer edge of the folded portion of the first bent plate to form the folded section.

[0007] As a further improvement of the present utility model, the connecting section includes a second bending plate and a third bending plate. One end of the second bending plate is connected to the outer edge of the folding part of the first bending plate, and the other end extends obliquely and is connected to the upper end of the third bending plate. The third bending plate extends downward obliquely.

[0008] As a further improvement of the present utility model, the folding section of the outer hook plate is riveted to the outer side wall of the inner hook plate.

[0009] As a further improvement of the present utility model, an installation groove is provided on the first bending plate for fixedly installing the outer hook plate on the sewing equipment.

[0010] As a further improvement of the present utility model, the inner hook plate is folded inwardly up and down to form a bent space that bends inward. One end of the clamping plate is arranged inside the bent space, and the clamping plate is detachably connected to the inner hook plate.

[0011] As a further improvement of the present utility model, the inner hook plate includes a vertical plate and a horizontal plate. The horizontal plates are symmetrically arranged above and below the two ends of the vertical plate respectively, and the vertical plate and the horizontal plate are vertically arranged to form a bent space that bends inward.

[0012] As a further improvement of the present utility model, a through second installation hole is provided on the vertical plate, and the outer hook plate and the inner hook plate are riveted through the second installation hole.

[0013] As a further improvement of the present utility model, the clamping plate includes a first clamping plate. Both ends of the first clamping plate are bolted to the inner hook plate respectively.

[0014] As a further improvement of the present utility model, the clamping plate further includes a second clamping plate. The second clamping plate is embedded between the inner hook plates at both ends, and the second clamping plate is arranged outside the first clamping plate. The first clamping plate and the second clamping plate are connected by bolts.

[0015] Compared with the prior art, the beneficial effects of the present utility model are as follows:

[0016] By providing an outer hook plate, an inner hook plate and a clamping plate, the inner hook plate is folded inwardly up and down to form a bent space that bends inward. One end of the clamping plate is arranged inside the bent space, and the clamping plate is detachably connected to the inner hook plate. The outer hook plate is riveted to the side wall of the bent space of the outer hook plate. During installation, the inner hook plate can be first installed on the sewing equipment, and then the outer hook plate and the inner hook plate can be installed and connected by rivets; it can be convenient to install the device on the sewing equipment, and the outer hook plate and the inner hook plate can be installed separately, and the relative positions between the outer hook plate and the inner hook plate can be adjusted during installation;

[0017] The folded section that folds inward can narrow the space size between the two ends of the clamping plate and their corresponding outer hook plates to a certain extent, making more full use of the space structure at both ends of the clamping plate. At the same time, it also more effectively avoids the touching phenomenon that occurs during the use of the thread clamping device, making the production process safer and more reliable, the product quality more effectively controlled and improved, the production failure rate low, and the product qualification rate high.
