The specific embodiment
As shown in Figure 1, be manual fast-holding fixture described in the utility model; Manually fast-holding fixture mainly comprises base 1, location-plate 2 and holds down assembly.
Location-plate 2 is vertically set on base 1; On location-plate 2, be provided with four location key seats, and dispose the alignment pin being used in conjunction with location key seat that is independent of location-plate 2.
The corresponding location-plate 2 that holds down assembly is arranged on base 1; The pressure head 4 and one that comprises a corresponding location-plate 2 of holding down assembly controls that described pressure head 4 presses to location-plate 2 or away from the telescopic component 3 of location-plate 2.
Described telescopic component 3 comprises:
One holder 31, described holder 31 is arranged on base 1; Described holder 31 is near side horizontally set one guide pipe of location-plate 2, and described guide pipe is perpendicular to location-plate 2, and first mouth of pipe of described guide pipe is towards location-plate 2;
One push rod 32, described push rod 32 activities are located in guide pipe, described pressure head 4 be arranged on described push rod 32 towards location-plate 2 first end;
One first connecting rod 33, the second end of the first end of described first connecting rod 33 and described push rod 32 is longitudinally hinged, and described first connecting rod 33 with described push rod 32 in same plane;
One second connecting rod 34, the second end of the first end of described second connecting rod 34 and described first connecting rod 33 is longitudinally hinged, and described second connecting rod 34 with described first connecting rod 33 in same plane, the second end of described second connecting rod 34 is longitudinally hinged on holder 31; Be that push rod 32, first connecting rod 33 and second connecting rod 34 threes are in same plane; And

Practical application of the present utility model:
The corresponding location-plate of pressure head, object is for correspondence is fixed on the workpiece on location-plate, thus accurate workpiece pressing.
When manual fast-holding fixture is during in idle condition, handle is flapped toward the rear of holder, and first connecting rod and second connecting rod close up and be together flapped toward the rear of holder, and push rod is in retracted state; The front and back position of described holder as shown in the figure.
Workpiece is placed on location-plate, then with alignment pin by workpiece stationary positioned; User is driving handle forward upwards simultaneously, presses down subsequently handle, and handle drives first connecting rod and second connecting rod forward and moves downward, now first connecting rod and second connecting rod to forward swing, open and press down; Meanwhile, first connecting rod promotes push rod and presses forward, thus pressure head workpiece pressing.
After completion of processing, user upwards pulls handle, pulls down backward subsequently fixed handle simultaneously, and handle drives first connecting rod 33 and second connecting rod upwards and motion backward, and now first connecting rod and second connecting rod close up and rotation backward; Meanwhile, first connecting rod 33 drives push rod to regain backward, leaves workpiece.
The cylindrical recesses portion of the compressed part in pressure head and the cylindrical hole of installing plate under the mating reaction with short cylindrical axle, can 360 degree rotation and can swing, become a Universal pressing head.Pressure head can swing, and principle is that cylindrical recesses portion in compressed part and the sphere of cylinder axis form space, thereby whole pressure head can form and swing according to sphere.Pressure head can coordinate the actual conditions rotation of workpiece and realize swing in order accurately to compress pressure head, thereby reaches accurately firm workpiece pressing.
Copper pressure head is softer, can protect workpiece not damaged by pressure.
The utility model is not limited to above-mentioned embodiment, if various changes of the present utility model or modification are not departed to spirit and scope of the present utility model, if within these changes and modification belong to claim of the present utility model and equivalent technologies scope, the utility model is also intended to comprise these changes and change.
