Description
Technical field
The utility model relates to a kind of parallel clamp.
Background technology
General vice clamp sheet material or hex nut is this kind of have a part of two parallel surfaces time, the following situation of easy appearance: jaw working face only contacts with the edge of work two corners, namely linear contact lay, this situation can cause two results: one. because contact is unstable, lean on so cause to clamp not strongly; Two. because general purpose tool hardness ratio part is high, and only contact with part corner, so easily destroy workpiece corner.And Producing reason is that an auxiliary lever mechanism only used by existing vice, jaw can not parallelly be opened, but horn mouth open.
Utility model content
For problems of the prior art, the purpose of this utility model is the technical scheme providing a kind of parallel clamp.
Described parallel clamp, is characterized in that comprising moving jaw, regular jaw, fixed handle and connecting rod, and moving jaw and regular jaw form parallel clamp clamping part; Described moving jaw right-hand member is provided with the first engaging lug, the first engaging lug is vertically arranged the first connecting hole and the second connecting hole; Described regular jaw right-hand member is provided with the second engaging lug, on the right side of second engaging lug, fixed handle is set, second engaging lug is vertically arranged the 3rd connecting hole and the 4th connecting hole, and when installing, the 3rd connecting hole and the 4th connecting hole are positioned at the right side of the first connecting hole and the second connecting hole; Described fixed handle left end is provided with the first moving jaw connecting hole and the first spacing hole, and described connecting rod two ends arrange the second moving jaw connecting hole and the second spacing hole respectively; The second described moving jaw connecting hole is connected by the first short pin shaft with the first connecting hole, first moving jaw connecting hole is connected by the second short pin shaft with the second connecting hole, second spacing hole is connected by the first long pin shaft with the 3rd connecting hole, and the first spacing hole is connected by the second long pin shaft with the 4th connecting hole; Described fixed handle with the second long pin shaft for fulcrum moves around fixed handle.
Described parallel clamp, is characterized in that described first engaging lug is set to two panels, and the first moving jaw connecting hole of fixed handle and the second moving jaw connecting hole of connecting rod are all equipped with between two panels first engaging lug.
Described parallel clamp, it is characterized in that described second engaging lug offers a cavity, compartment is received and is arranged connecting rod and fixed handle.
Described parallel clamp, is characterized in that being provided with packing ring between the second spacing hole of described connecting rod and the 3rd connecting hole of the second engaging lug.
The utility model make use of quadric chain, jaw is opened and remains parastate, so just there is not the shortcoming clamped not strongly by with contact surface instability; And can not stagger during jaw clamping of the present utility model, the design of handle is also more humane, easy to use.

Detailed description of the invention
Below in conjunction with Figure of description, the utility model is described further:
Parallel clamp, comprises moving jaw 1, regular jaw 2, fixed handle 3 and connecting rod 4, and moving jaw 1 and regular jaw 2 form parallel clamp clamping part; Moving jaw 1 right-hand member is provided with on the first engaging lug 5, first engaging lug 5 and vertically arranges the first connecting hole 12 and the second connecting hole 13; Regular jaw 2 right-hand member is provided with the second engaging lug 6, on the right side of second engaging lug 6, fixed handle 7 is set, second engaging lug 6 is vertically arranged the 3rd connecting hole 14 and the 4th connecting hole 15, and when installing, the 3rd connecting hole 14 and the 4th connecting hole 15 are positioned at the right side of the first connecting hole 12 and the second connecting hole 13; Fixed handle 3 left end is provided with the first moving jaw connecting hole 17 and the first spacing hole 18, and connecting rod 4 two ends arrange the second moving jaw connecting hole 19 and the second spacing hole 20 respectively; Second moving jaw connecting hole 19 is connected by the first short pin shaft 8 with the first connecting hole 12, first moving jaw connecting hole 17 is connected by the second short pin shaft 9 with the second connecting hole 13, second spacing hole 20 is connected by the first long pin shaft 10 with the 3rd connecting hole 14, and the first spacing hole 18 is connected by the second long pin shaft 11 with the 4th connecting hole 15; Fixed handle 3 moves around fixed handle 7 for fulcrum with the second long pin shaft 11.
As preferably, the first engaging lug 5 is set to two panels, and the first moving jaw connecting hole of fixed handle 3 and the second moving jaw connecting hole of connecting rod are all equipped with between two panels first engaging lug; Second engaging lug 6 is offered a cavity 16, compartment is received and is arranged connecting rod and fixed handle, does not misplace when ensureing clamping; Packing ring can be set between the second spacing hole of connecting rod and the 3rd connecting hole of the second engaging lug, and then control link is positioned at center, does not depart from.
Parallel clamp of the present utility model mainly make use of quadric chain, suppose that regular jaw is motionless, when opening fixed handle, fixed handle rotates around the second long pin shaft, due to lever principle, promote moving jaw and move upward on the left of fixed handle, power is delivered on the short pin shaft of moving jaw top first, at this moment to obtain power consistent with the fixed handle direction of motion for connecting rod, and connecting rod moves around the first long pin shaft simultaneously.Because their centre-to-centre spacing does not change, therefore moving jaw and regular jaw remain parallel relation.
