The tangent mechanism of sewing machine
Technical field
Textile technology field is the utility model is related to, refers in particular to the tangent mechanism of sewing machine.
Background technology
Existing sewing machine after work is completed, it is necessary to artificial hand cuts line by scissors, it is cumbersome, and cut after having cut
Knife is arbitrarily placed, and influences job safety.
The content of the invention
The purpose of this utility model is overcome the deficiencies in the prior art, there is provided a kind of sewing machine it is rational in infrastructure, cut
The good tangent mechanism of line effect.
To achieve the above object, technical scheme provided by the utility model is:The tangent mechanism of sewing machine, it includes
There is the fixed plate on sewing machine head, the Level tune plate of L-shaped, Level tune plate bottom are movably installed with fixed plate
Tangent line seat is installed, the tangent line seat end of sewing machine head side extends to form hinge plate, and hinge plate bottom is movably hinged with cropping shears,
Tangent line seat bottom is provided with tangent line cylinder, and tangent line cylinder one end is connected with tracheae, and the other end passes through connector and cropping shears one end
Be hinged, the cropping shears other end is trimming end, and trimming end is located at below sewing machine head.
It is in X shapes that described cropping shears is be hinged by the symmetrical cutter hub of two-strip structure, and two cutter hubs at trimming end are provided with inner arc
Face is relative to be cut line groove, and two cutter hub other ends are hinged with corresponding connecting rod one end respectively, and the connecting rod other end is hinged on connector
On, two connecting rods after being hinged form V-arrangement, and V-arrangement tip is hinged with connector.
The perpendicular wall of described Level tune plate is provided with two parallel longitudinally adjust grooves, longitudinally adjust groove with fixed plate
Corresponding regulating bolt connection.
The cross wall of described Level tune plate is provided with two parallel lateral adjustments grooves, and tangent line seat passes through tangent line seat bolt
On lateral adjustments groove.
For the utility model after using such scheme, the structure and mounting means be not described in detail can use market conventional
Structure, this programme can be directly installed on existing sewing machine and use, by longitudinally adjust groove and lateral adjustments groove by tangent line
Cut and be adjusted to correct position, switch may be mounted on table top or on sewing machine, drive tangent line by Telescopic-cylinder during tangent line
Cut line shearing, it is good using rational in infrastructure, the trimming effect after this programme, it can be fitted by longitudinally adjust groove and lateral adjustments groove
The sewing machine of different model is answered to use.

Embodiment
With reference to all accompanying drawings, the utility model is described in further detail, and preferred embodiment of the present utility model is:Ginseng
See accompanying drawing 1 and accompanying drawing 2, the tangent mechanism of the sewing machine described in the present embodiment includes the fixation on sewing machine head
Plate 1, the Level tune plate 2 of L-shaped is movably installed with fixed plate 1, and the perpendicular wall of Level tune plate 2 is provided with two parallel longitudinal directions
Regulating tank, the regulating bolt connection corresponding with fixed plate 1 of longitudinally adjust groove, the bottom of Level tune plate 2 are provided with tangent line seat 3,
The cross wall of Level tune plate 2 is provided with two parallel lateral adjustments grooves, and tangent line seat 3 is arranged on by tangent line seat bolt and laterally adjusted
Save on groove, the end of tangent line seat 3 of sewing machine head side extends to form hinge plate, and hinge plate bottom is movably hinged with cropping shears 5, tangent line
3 bottoms of seat are provided with tangent line cylinder 6, and the one end of tangent line cylinder 6 is connected with tracheae, and the other end passes through connector and the one end of cropping shears 5
Be hinged, the other end of cropping shears 5 is trimming end, and trimming end is located at below sewing machine head, and described cropping shears 5 is by two-strip structure pair
It is in X shapes that the cutter hub of title is be hinged, two cutter hubs at trimming end be provided with intrados it is relative cut line groove 7, two cutter hub other ends divide
It is not hinged with corresponding one end of connecting rod 4, the other end of connecting rod 4 is hinged on connector, and two connecting rods 4 after being hinged form V-arrangement, V
Shape tip is hinged with connector.The structure and mounting means that the present embodiment is not described in detail can use market conventional structure, this
Embodiment can be directly installed on existing sewing machine and use, and be adjusted to cropping shears by longitudinally adjust groove and lateral adjustments groove
Correct position, switch may be mounted on table top or on sewing machine, drive cropping shears by line by Telescopic-cylinder during tangent line
Shearing, it is good using rational in infrastructure, the trimming effect after the present embodiment, it is adapted to not by longitudinally adjust groove and lateral adjustments groove
Sewing machine with model uses.
Embodiment described above is only the preferred embodiment of the utility model, not limits reality of the present utility model with this
Apply scope, therefore the change that all shape, principles according to the utility model are made, it all should cover in the scope of protection of the utility model
It is interior.
