Detailed Description

The present invention will be further explained with reference to the embodiments shown in the drawings.

The round corner standing buckle shown in fig. 10 and 11 has a buckle body 21 with a round front surface and a flat round side surface, and a round foot 20 (made of aluminum or plastic) with a round back surface, wherein a wire hole X1 is formed in the round foot, penetrates through the left side and the right side of a round corner (see fig. 11), and the axis of the wire hole is parallel to the long axis of the flat round.

In the round foot vertical buckle clip shown in the attached drawing, a frame body 8 consists of an upper frame body 8-1 and a lower frame body 8-2 which are hinged (hinged shafts 8-3) into a whole; the lower frame body is used for being fixed on a sewing machine table; the positioning seat 2, the swing arm 5 and the spring 6 are all mounted on the upper frame body, wherein the positioning seat 2 is fixed at the front end of the upper frame body, and the swing shaft 3 can be hinged on the frame body in a swinging mode around a vertical axis; the swing arm is fixed on the swing shaft (in the figure, the swing arm is transversely inserted into a transverse hole of the swing shaft and then is screwed and fixed by a screw); one end of the spring is fixed (fixed by a screw) on the connecting frame 7 on the frame body, and the other end of the spring applies force to the swing arm to enable one end of the swing arm to swing towards the positioning seat (clockwise swing can be known in figure 3) so as to press the button on the positioning seat. The structure is similar to the existing button clip.

The utility model discloses preparation has slot 2-1 on the positioning seat, and the shape of slot is fit for with the round foot surface that the round foot was buckled immediately for the sliding friction power increase after the round foot embedding that the round foot was buckled immediately, can keep the location that the round foot was buckled immediately stable when the sewing (if the round foot was buckled immediately and is fixed a position unstably, can cause the eedle to break the needle). The opening of the concave groove faces to the right side direction (see figure 4) to be matched with the swing arm to clamp and press the round foot standing buckle; the concave groove is also provided with an opening 2-2 which is communicated in the vertical direction and is communicated with the edge of the opening, and the lower frame body is provided with a through hole 8-21 which is vertically communicated and vertically corresponds to the opening of the concave groove so as to provide space for the sewing movement of the machine needle. As can be seen from fig. 7, the opening 2-2 and the thread hole X1 in the round pin are both the up-and-down movement space of the needle during sewing, and the needle drives the sewing thread to sew and fix the round pin vertical button on the cloth.

Furthermore, the bottom of the positioning seat is lifted by a supporting sheet 2-3 (stainless steel sheet), one end of the supporting sheet is fixedly connected with the upper frame body (as can be known from fig. 2, the right end of the supporting sheet is fixedly welded with the upper frame body, and the positioning seat is fixedly welded on the supporting sheet); therefore, the round foot standing buckle can be more effectively and stably positioned on the concave groove. The supporting sheet is also provided with an opening corresponding to and communicated with the opening 2-2 so as to be beneficial to the sewing movement of the needle.

Furthermore, a rubber end 1-1 is sleeved at the end part of the swing arm; the swing arm pushes the round foot vertical buckle to the concave groove part of the positioning seat through the rubber end, so that the round foot vertical buckle can be protected from being damaged, and the friction force can be increased to enable the round foot vertical buckle to be more stably positioned.
