Abstract
The utility model discloses a thread-grabbing mechanism of a sewing machine, comprising a thread-grabbing clip composed of two elastic thread-grabbing rods; a thread-grabbing hook located between the two thread-grabbing rods, wherein the tail end of the thread-grabbing hook is connected with a drive device, the drive device can drive the thread-grabbing hook to perform a rectilinear motion, and the thread-grabbing hook is opposite with the needle of the sewing machine; and a connection bracket via which the drive device is fixed on the nose panel of the sewing machine. The drive device drives the thread-grabbing hook to stretch out between the two thread-grabbing rods and hook a thread end stretching out from the needle at first before the sewing machine starts to sew, and then the drive device drives the thread-grabbing hook to reset; and the thread end can be clipped by the two thread-grabbing rods when the thread-grabbing hook passes through the two thread-grabbing rods. In this way, the length of a thread end on the needle when the sewing machine starts to sew can be efficiently reduced, thereby avoiding a 'bird-nest thread reel' appearing on the back of a joint material. The thread-grabbing mechanism of a sewing machine further has the advantages of being simple in structure, convenient in operation, stable in performance, low in manufacturing cost etc.

Preferably, said cylinder is a single-acting cylinder.
Preferably, said connection support is provided with and is used for the installing hole that is connected with said head of sewing machine panel, and said installing hole is a slotted hole.
Technique scheme has following beneficial effect: adopts this Sewing machines to grab line mechanism, before Sewing machines is made, earlier catches and clamp through grabbing the line mechanism the end of a thread of will reaching the standard grade, and with the clamping of reaching the standard grade of eedle opposite side; Like this when stitching sewing machine first pin; Along with the decline of eedle height, stretch out the end of a thread of reaching the standard grade of eedle and will be pulled back and shortening gradually, when eedle drops to suitable height; Stretch out eedle the end of a thread and eedle opposite side reach the standard grade released; Stretching out the end of a thread of eedle this moment will so just can be avoided " a nest like ball of string " occurring at the back side of sewing by effective shortening, guarantees the quality of sewings.The utility model Sewing machines is grabbed line mechanism and is also had advantages such as simple in structure, easy to operate, stable performance, low cost of manufacture.
Above-mentioned explanation only is the general introduction of the utility model technical scheme; In order more to know the technological means of understanding the utility model; And can implement according to the content of specification, below this patent is elaborated with the preferred embodiment and the conjunction with figs. of the utility model.
Description of drawings
Fig. 1 is the structural representation that the utility model embodiment is connected with Sewing machines.
Fig. 2 is the decomposing schematic representation of the utility model embodiment.
The specific embodiment
Describe in detail below in conjunction with the preferred embodiment of accompanying drawing to the utility model.
Like Fig. 1, shown in 2, this Sewing machines is grabbed line mechanism and is comprised and grab wire clamp, grab parts such as line colludes 4, drive unit.As an embodiment of the utility model, drive unit is a cylinder 6, and cylinder 6 is a single-acting cylinder, and cylinder 6 is made up of parts such as end cap 61, cylinder body 62, O RunddichtringO 63, piston 64, piston rod 65, springs.Grab wire clamp and be made up of two flexible line bars 5 of grabbing, the front end of grabbing line bar 5 is provided with elbow.The cylinder body 62 of cylinder 6 is provided with a clip 9, and clip 9 is connected on the cylinder body 62 through lock screw 10, and the rear end that two elasticity is grabbed line bar 5 is fixed on the clip 9, and two front ends of grabbing line bar 5 close up and form folder shape structure.
