Mode so that elastic rod is convenient to be installed, and can be convenient for changing when elastic failure again.
As preferably, substrate is detachable connection with panel.Such as substrate can be pacified by screw with panel
Dress, can connect again by the way of chute clamping.
In order to make bottom line shuttle make it be narrowly focused towards installation position when being installed on electric magnet, and along with electromagnetism
Railway transportation is dynamic to be directly assembled on installation position, it is not necessary to manually adjusts, as preferably, also includes the end of for
The detent mechanism of line shuttle location.
As preferably, described detent mechanism includes being arranged on the plug on electric magnet magnetic end face and correspondence
Being arranged on the slot on bottom line shuttle, when electric magnet and bottom line shuttle adhesive, plug inserts in slot.Plug
Pre-set according to bottom line shuttle installation position with the position of slot, after plug inserts in slot, make
Obtain bottom line shuttle just can be directly loadable in installation position, it is not necessary to carry out again circumferentially rotating adjustment.
As preferably, plug is each with slot has two by oneself, when electric magnet and bottom line shuttle adhesive, and two plugs
In two slots of corresponding insertion.Use two-point locating to make location more accurate, and avoid bottom line shuttle to produce
Rotate.
Have employed the design concept of the present utility model of technique scheme and provide the benefit that:
This utility model provides a kind of bottom line shuttle mechanism for assembling-disassembling that can quickly carry out operating and dismounting side
Method, specifically uses the mode of magnet switching electricity to make electric magnet produce magnetic force and bottom line shuttle adhesive or disengaging,
Drive it to move when adhesive, when after the good bottom line of peg or spindle winding, shuttle entirety is installed；And work as bottom line
When being finished, adhesive shuttle entirety takes away installation position to separate again；Whole disassembly process achieves machinery certainly
Dynamicization, need not need the most as before to shut down sewing machine or cord, more manually pull opening,
Boot up again after finishing changing, provide a kind of faster more efficient way to the dismounting of bottom line shuttle.
