Embodiment
Specific embodiment of the present utility model is described further below in conjunction with the accompanying drawings.Herein it should be noted that
It is used to help understand the utility model for the explanation of these embodiments, but does not form to restriction of the present utility model.This
Outside, as long as technical characteristic involved in each embodiment of the utility model disclosed below does not form conflict each other
Can is mutually combined.
As depicted in figs. 1 and 2, a kind of needle plate drawing machine wire-clamping device 1 disclosed in the utility model, including it is fixed on clamp
Tension seat 12 on oscillating rod 2, clamp sliding block 13, tension seat 12 and clamp are provided between tension seat 12 and clamp oscillating rod 2
Spring (not shown) is connected between sliding block 13, is fixedly installed in clamp sliding block 13 and stings tight block 11, after tension seat 12
Side's (in the present embodiment, rear refers to X-direction) is provided with thread tension stud 14, and thread tension stud 14 is fixed on clamp by rotating dog 15
On oscillating rod 2 so that thread tension stud 14 can rotate relative to clamp oscillating rod 2.
With reference to figure 2, the lower end of tension seat 12 sets fluted 121, and the front end of tension seat 12 is provided with the second sawtooth portion
122。
With continued reference to Fig. 2, clamp sliding block 13 includes slip front 131, sliding block middle part 132 and the sliding block rear end being sequentially connected
133, one end connection tension seat 12 of spring, other end connection sliding block rear end 133, sliding block middle part 132 is placed in groove 121, made
Obtaining clamp sliding block 13 can move along the X direction in tension seat 12, and 132 length is more than the length of tension seat 12 in the middle part of sliding block,
The width of slip front 131 and sliding block rear end 133 is all higher than in the middle part of sliding block 132 width so that clamp sliding block 13 is in tension seat
When being moved along the X direction in 12, before can be blocked by slip front 131, behind can be blocked by sliding block rear end 133.Slip front
Through hole 134 is provided with 131.
With continued reference to Fig. 2, sting tight block 11 and be placed in through hole 134, the rear and front end for stinging tight block 11 is provided with the first sawtooth
Portion 111, the first sawtooth portion 111 and the second sawtooth portion 122, which work in coordination, stings tightly.
With continued reference to Fig. 2, the front end of thread tension stud 14 is provided with cam 142, and cam 142 is connected with handle 141, cam 142
The first rotating pin hole 143 is inside provided with, clamp oscillating rod 2 is provided with second in the corresponding position with the first rotating pin hole 143
