Preferably, the reinforcement quarter butt is in flat.
Preferably, the reinforcement quarter butt is articulated with the connecting rod, vice body by rivet.
Preferably, connection position of the articulated position for strengthening quarter butt and the vice body apart from the extension spring and the vice body
Put 2-3 centimetres.
By at extension spring rear, one reinforcement quarter butt is set, even if length of the present utility model is larger, clamping force is larger,
The deformation of connecting rod, vice body can also be prevented effectively from.
Brief description of the drawings
Fig. 1 is structure (perspective) schematic diagram of the utility model embodiment；
Fig. 2 be Fig. 1 in along A-A cross-sectional view；
Fig. 3 is the fixed pliers head of the other forms that the utility model embodiment can be configured, the structure chart of movable binding clip.
Specific embodiment
The utility model is described in further details with reference to the accompanying drawings and detailed description.
As shown in figure 1, the utility model embodiment includes vice body 1, connecting rod 2, pole 3, clamp handle 4, opening handle 5, regulation spiral shell
Nail 6, fixed pliers head 7, movable binding clip 8, rocking bar 9, extension spring 100, reinforcement quarter butt 1121.Wherein, the retaining mechanism of the present embodiment is
Pole 3, opening handle 5 between the rear end of vice body 1, clamp handle 4 etc., it is that mature technology is repeated no more.
Specifically, fixed pliers head 7 is fixed on the front end of vice body 1, and movable binding clip 8 is articulated with front end and the pincers of connecting rod 2
The front end of body 1, the middle part of rocking bar 9 and vice body 1, the rear end of connecting rod 2, the front end of clamp handle 4 are hinged.Connecting rod 2 and vice body 1 are in shaft-like
Structure, and connecting rod 2 and the less parallel of vice body 1, be close to, space 102 therebetween is very narrow, and in running, it is empty
The width of gap 102 is substantially unchanged.As shown in Fig. 2 the cross section of the cross section of connecting rod 2 and vice body 1 takes the shape of the letter U, and the two
Opening is oppositely arranged, and the inside of vice body 1 is deep trouth 10, the inside of connecting rod 2 is deep trouth 20.One end of extension spring 100 is connected to vice body 1
Anterior inside (the big portion in the end is located in deep trouth 10)；The other end of extension spring 100 then stretches into the inside of connecting rod 2 (end of extension spring 100
Then big portion is located in deep trouth 20) and be connected to inside the deep trouth 20 of connecting rod 2, specific link position is near connecting rod 2 and adjustable clamp
First 8 hinged place, the effect of extension spring 100 is that drive link 2 is moved rearwards by, and then driving activity binding clip 8 opens.
When the present embodiment is more long, namely connecting rod 2, vice body 1 it is more long when, the two may be susceptible to deformation, in consideration of it, this
Embodiment sets up a reinforcement quarter butt 1121.As shown in Figure 1 and Figure 2, the reinforcement quarter butt 1121 is located at the rear of extension spring 100, one
It is hinged inside the deep trouth 20 of end insertion connecting rod 2 and with connecting rod 2 by rivet 21, inside the deep trouth 10 of other end insertion vice body 1
And it is hinged by rivet 11 with vice body 1.When connecting rod 2 is moved back and forth, strengthen the reciprocally swinging therewith of quarter butt 1121.
Preferably, the position near activity binding clip 8 inside the deep trouth 20 of connecting rod 2 is provided with transverse axis 201, extension spring 100 it is another
One end is hooked on transverse axis 201.
As shown in figure 1, the only middle part small part of extension spring 100 is exposed outside by space 102, substantially avoided outer
The mechanical shock on boundary, damage.
Because extension spring 100 is not reconnected with rocking bar 9, therefore, rocking bar 9 is designed as arc platy structure, one by the present embodiment
End is articulated with the middle part of vice body 1, the other end and is articulated with the rear end that the front end of clamp handle 4, middle part are articulated with connecting rod 2, and rocking bar 9 is facing forward
It is raised.The rocking bar 9 of arc platy structure not only move flexibly, good appearance, it is and less with material, it is cost-effective.
Preferably, the reinforcement quarter butt 1121 of the present embodiment is in flat structure, similar to tabular.Also, strengthen quarter butt
1121 with the articulated position of vice body 1 apart from extension spring 100 and vice body 1 link position at least 2cm, such as 2-3 centimetres.The present embodiment
One reinforcement quarter butt is set, if set it is multiple strengthen quarter butts, can to the present embodiment increase frictional resistance, technology difficulty,
Cost and the intensity (since it is desired that punching, install rivet) of connecting rod and vice body may be reduced.
In addition, movable binding clip of the present utility model, fixed pliers head can be not only the friction clamp head shown in Fig. 1, and can be with
Movable binding clip 80 wider shown in Fig. 3, fixed pliers head 70, movable binding clip 80, fixed pliers head 70 are installed on connecting rod and vice body
When, it is substantially vertical with the two on the whole.It is of course also possible to when movable binding clip 80, fixed pliers head 70 are installed on into connecting rod, vice body,
Form oblique mounting structure.
To sum up, the utility model can increase bulk strength, connecting rod, vice body difficult deformation.
As known by the technical knowledge, the utility model can be by other essence without departing from its spirit or the reality of essential feature
Scheme is applied to realize.Therefore, embodiment disclosed above, for each side, is all merely illustrative, and is not only
's.It is all in the range of the utility model or in the change being equal in the range of the utility model by the utility model bag
Contain.
