Description
Technical field
The present invention relates to a kind of seam clothing device, particularly a kind of changeable type sewing machine.
Background technology
Contemporary chinese economy high speed development; sewing machine is widely used in clothing are processed; traditional sewing machine simply simply fixes eedle; the problem that eedle often rotates in workman's use procedure or comes off; and having reinstalled eedle is expend some times, virtually reduce the production efficiency of workman.
Summary of the invention
In order to solve the problems referred to above, the invention provides that a kind of fixing eedle is firm and the sewing machine of readily accessible eedle.
The technical solution adopted in the present invention is: a kind of changeable type sewing machine, comprises handpiece case, is fixed on the support bar below handpiece case, is fixed the swivel becket connecting handpiece case by support bar；Also comprise eedle, for fixing the connecting rod of eedle and for locking the jacket casing of connecting rod；Eedle comprises syringe needle and is connected to the extension diameter section of syringe needle one end；The front side of connecting rod is had at least twice half notch by axle center to edge and the front side of connecting rod is divided at least two monomer, and the front side of connecting rod has a circular hole along axle center outward direction, and extension diameter section connects circular hole, and the diameter of circular hole is less than the diameter of extension diameter section；Jacket casing is arranged on outside connecting rod, and the inner side of jacket casing offers corresponding screw thread with the outside of connecting rod；Connecting rod connects swivel becket.
Preferential, the front side of connecting rod is had three equally distributed half notches by axle center to edge and the front side of connecting rod is divided into three equally distributed monomers.
Preferential, connecting rod with swivel becket offers corresponding nail, be provided with pin in nail.
Preferential, eedle inserts the extension diameter section place of half notch and arranges multiple projection.
Preferential, also comprise the fixing bar being vertically mounted on handpiece case and the bracing frame being vertically mounted on fixing bar；The outer wall of swivel becket offers U-type groove, in U-type groove, is provided with bracing frame.
Preferential, jacket casing outer wall is provided with anti-slip veins.
The invention have the benefit that
(1) tail end of eedle adopts the mode inserted and compress to be fixed in connecting rod, and the extension diameter section place of eedle arranges multiple projection, increase the frictional force between eedle and connecting rod, it is to avoid the situation that eedle in use shakes occurs.
(2) this sewing machine installs eedle conveniently, it is simple to dismounting, and fixing eedle is firm.

Detailed description of the invention
As it is shown in figure 5, a kind of changeable type sewing machine, comprise handpiece case 1, support bar 2, shank 3, swivel becket 4, bracing frame 5, dribbling bin 6, jacket casing 7, eedle 8, fixing bar 9, pin 10, monomer 11, half notch 12 and connecting rod 13.
As Figure 1-Figure 4, eedle 8 comprises syringe needle and is connected to the extension diameter section of syringe needle lower end；The front side of connecting rod 13 is had three and half notches 12 by axle center to edge thus the front side of connecting rod 13 is divided into three monomers 11, have a circular hole in the front side of connecting rod 13 along axle center outward direction, the diameter of circular hole less than the diameter of extension diameter section so that monomer 11 can be flicked to the direction away from axle center when eedle 8 inserts the front side of connecting rod 13 central；Jacket casing 7 is provided with female thread, and connecting rod 13 is provided with the external screw thread of corresponding jacket casing 7；When jacket casing 7 is assemblied on the outer wall of connecting rod 13, screws jacket casing 7 when eedle 8 inserts connecting rod 13 and monomer 11 can be made to compress extension diameter section.The fixed form of eedle 8 and connecting rod 13 is compressed so that it is firm that overall structure consolidates more by screwing jacket casing 7.
As shown in Figure 6, the sidewall of swivel becket 4 offers U-type groove 14, and bracing frame 5 engages U-type groove 14 to be fixed swivel becket 4 and prevent vertical direction between swivel becket 4 and support bar 2 to be moved.Swivel becket 4 is fixed with support bar 2 to be connected and prevents swivel becket 4 to be moved in the horizontal plane, and the top of support bar 2 is vertically fixing connects handpiece case 1；The groove of column type is offered at the top, lower end of swivel becket 4, and connecting rod 13 offers corresponding nail with on swivel becket 4, is provided with the pin 10 preventing swivel becket 4 and connecting rod 13 from relatively rotating in nail.The upper end of connecting rod 13 with offer corresponding screw thread in groove, connecting rod 13 rotates into groove and realizes both being rotationally connected, now pin is inserted the possibility being effectively prevented both generation relative movements in the course of the work in nail so that both connections are more stable, more firmly.
Dribbling bin 6 is rotatably connected on the sidewall of swivel becket 4.The tail end of fixing bar 9 is vertically fixed on handpiece case 1, vertical fixing connection bracing frame 5 on head end；Jacket casing 7 outer wall is provided with anti-slip veins.Eedle 8 inserts the extension diameter section place of half notch 12 and arranges multiple projection, is highly 0.1mm.
Above-described embodiment is the present invention preferably embodiment; but embodiments of the present invention are also not restricted to the described embodiments; the change made under other any spirit without departing from the present invention and principle, modification, replacement, combination, simplification; all should be the substitute mode of equivalence, be included within protection scope of the present invention.
