Through hole is provided with the upper correspondence sleeve connection, the through hole is connected with accommodating cavity, and the depression bar is arranged in accommodating cavity body,
One end of depression bar offsets with spring, and the other end of depression bar stretches out the roll to be formed for placing shuttle by the through hole；Institute
The side for stating sleeve is provided with the first neck and the second neck in the axial direction, and the first neck of connection and the second neck is logical
Road, first neck, the second neck and passage form function switch groove, and the depression bar is provided with gear with one end that spring offsets
Bar, the pin is in the function switch groove.Utility model works principle：When handwheel is not as winding mechanism, gear
Bar is arranged far from the second neck of rotation section, and roll is collected in rotation section, and its head is only protruded fraction and is used for
Operation, the other end compression spring of depression bar, handwheel now use for common handwheel；When handwheel is as winding mechanism, turn
Dynamic roll, pin is left the second neck and enter in passage, in the presence of spring force, the fully extended rotation of roll
Outside portion, now it is rotated further by roll and drives depression bar and pin to rotate, pin is entered the first neck, so as to limit the axle of roll
, now can be by shuttle core sheath on roll to motion, main shaft drives handwheel rotation during work, handwheel drives shuttle to be sent
Line.
As an improvement, the rotation section includes annulus and the cover plate located at annulus one end, it is anti-that the annulus is provided with first
Draw runner line, the through hole are located on cover plate.
As an improvement, reinforcing plate is provided between the rotation section and sleeve.
As an improvement, the medial surface of the reinforcing plate side with sleeve, the inwall of annulus and cover plate respectively is connected.
As an improvement, the side surface of the roll is provided with the second skid resistance strip, the end face surface of roll is provided with the
Three skid resistance strips.
Caused beneficial effect is the utility model compared with prior art：
By the use of existing mechanism handwheel as the mounting seat of shuttle, part can be saved, simplifies structure, reduces the body of sewing machine
Product.
Brief description of the drawings
Fig. 1 is the utility model structure diagram.
Fig. 2 is the utility model decomposition view.
Embodiment
With reference to Figure of description, the utility model is described in further detail.
As shown in Figure 1, 2, a kind of winding mechanism of sewing machine, including the handwheel 2 of the one end of main shaft 1 is arranged on, motor passes through biography
Motivation structure drives main shaft 1 to rotate, and main shaft 1 drives shank.The handwheel 2 is arranged on the rear end of body, and handwheel 2 includes rotation section
21st, sleeve 22 and depression bar 3.The rotation section 21 includes annulus and the cover plate located at annulus one end, and the annulus is provided with first
Skid resistance strip, the through hole are located on cover plate；Reinforcing plate 26, the reinforcing plate 26 are provided between the rotation section 21 and sleeve 22
The medial surface of the side with sleeve 22, the inwall of annulus and cover plate is connected respectively.One end of the sleeve 22 connects with rotation section 21
Connect, the other end of sleeve 22 is connected with main shaft 1, and accommodating cavity is provided with the sleeve 22, spring is provided with the accommodating cavity body
27, the junction of sleeve 22 is corresponded on the cover plate of the rotation section 21 and is provided with through hole, and the through hole connects with accommodating cavity；Institute
State depression bar 3 to be arranged in accommodating cavity body, one end and the spring 27 of depression bar 3 are offseted, and the other end of depression bar 3 is stretched out by the through hole
Form the roll 31 for placing shuttle；The side surface of the roll 31 is provided with the second skid resistance strip 311, roll 31
