The specific embodiment
Combine accompanying drawing that the utility model is done further detailed explanation now.These accompanying drawings are the sketch map of simplification, the basic structure of the utility model only is described in a schematic way, so it only show the formation relevant with the utility model.
The foreign material of the utility model as shown in Figure 2 are drawn first specific embodiment of pincers clearly, comprise the effect pincers 4 that driving mechanism 1, telescoping mechanism 2, sleeve 5, linkage 3 and bar and pincers are welded, and driving mechanism 1 is fixedly mounted on the sleeve 5 and is hinged with telescoping mechanism 2; Telescoping mechanism 2 is set with sleeve 5; Telescoping mechanism 2 external parts and linkage 3 are hinged, are hinged with effect pincers 4 on the linkage 3, and driving mechanism 1 comprises crank 7; Telescoping mechanism 2 comprises screw rod 6; Crank 7 is fixedly connected with screw rod 6, and screw rod 6 is threaded with sleeve 5, and screw rod 6 external part two ends are an end of hinged two second connecting rods 32 respectively; One end of the bar part of two effect pincers 4 is fixedly hinged at the two ends of sleeve 5 external parts, and the pliers part of effect pincers 4 is hinged with the other end of two second connecting rods 32 respectively.When manual rotary crank 7, driven and be fixedly connected on moving axially of screw rod 6 on the crank 7, the second connecting rod 32 of screw rod 6 external parts is because moving axially of screw rod 6; Make second connecting rod 32 strut and tighten up; Strutting and tightening up of second connecting rod 32 causes opening and closure of effect pincers 4, owing to adopt screw rod 6, opens even operating personnel are openhanded; Effect pincers 4 are opened voluntarily, therefore reached the purpose of a self-locking.
The foreign material of the utility model as shown in Figure 3 are drawn second specific embodiment of pincers clearly, comprise the effect pincers 4 that driving mechanism 1, telescoping mechanism 2, sleeve 5, linkage 3 and bar and pincers are welded, and driving mechanism 1 is fixedly mounted on the sleeve 5 and is hinged with telescoping mechanism 2; Telescoping mechanism 2 is set with sleeve 5; Telescoping mechanism 2 external parts and linkage 3 are hinged, are hinged with effect pincers 4 on the linkage 3, and driving mechanism 1 comprises rocking bar 8; Telescoping mechanism 2 comprises slide bar 9; Rocking bar 8 is fixedly hinged on sleeve 5, and an end of rocking bar 8 is connected with first connecting rod 31, and first connecting rod 31 is hinged with slide bar 9; Slide bar 9 is sleeved on the sleeve 5; One end of the bar of two effect pincers 4 is hinged on the both sides of slide bar 9 external parts respectively, and the bar part of two effect pincers 4 is hinged with two third connecting rod 33 1 ends respectively near an end of pincers, and the other end of two third connecting rods 33 is fixedly hinged at the two ends of sleeve 5 external parts.When manually lifting rocking bar 8, first connecting rod 31 drives stretching out of slide bar 9, thereby promotes opening of third connecting rod 33; Because effect pincers 4 one ends are hinged with third connecting rod 33, and effect pincers 4 other ends are fixedly hinged on slide bar 9 external parts, so effect pincers 4 can be strutted; When manual depression rocking bar 8; Slide bar 9 indentations, thus induced effect clamps 4 closures, has so just reached the purpose that grasps.
The foreign material of the utility model as shown in Figure 4 are drawn the 3rd specific embodiment of pincers clearly, comprise the effect pincers 4 that driving mechanism 1, telescoping mechanism 2, sleeve 5, linkage 3 and bar and pincers are welded, and driving mechanism 1 is fixedly mounted on the sleeve 5 and is hinged with telescoping mechanism 2; Telescoping mechanism 2 is set with sleeve 5; Telescoping mechanism 2 external parts and linkage 3 are hinged, are hinged with effect pincers 4 on the linkage 3, and driving mechanism 1 comprises rocking bar 8; Telescoping mechanism 2 comprises slide bar 9; Rocking bar 8 is fixedly hinged on sleeve 5, and an end of rocking bar 8 is connected with first connecting rod 31, and first connecting rod 31 is hinged with slide bar 9; Slide bar 9 is sleeved on the sleeve 5; Slide bar 9 external parts are hinged with the bar part of hinged respectively two the effect pincers 4 of 34, two the 4th connecting rod 34 other ends of two the 4th connecting rods respectively, and the mid portion cross-articulation of the bar of two effect pincers 4 is in sleeve 5 external parts.When rocking bar 8 was lifted, first connecting rod 31 drove stretching out of slide bar 9, owing to have opening on the sleeve 5; So the 4th hinged on slide bar 9 external parts connecting rod 34 can directly be placed in the opening, has so just saved the space of structure, be applicable to that small pipeline removes contamination; Owing to adopt the structure of cross-articulation here, strutting of two the 4th connecting rods 34 causes acting on opening of pincers 4; Packing up of two the 4th connecting rods 34 causes that effect clamps 4 closure.
The foreign material of the utility model as shown in Figure 5 are drawn the 4th specific embodiment of pincers clearly, comprise the effect pincers 4 that driving mechanism 1, telescoping mechanism 2, sleeve 5, linkage 3 and bar and pincers are welded, and driving mechanism 1 is fixedly mounted on the sleeve 5 and is hinged with telescoping mechanism 2; Telescoping mechanism 2 is set with sleeve 5; Telescoping mechanism 2 external parts and linkage 3 are hinged, are hinged with effect pincers 4 on the linkage 3, and driving mechanism 1 comprises rocking bar 8; Telescoping mechanism 2 comprises slide bar 9; Rocking bar 8 is fixedly hinged on sleeve 5, and an end of rocking bar 8 is connected with first connecting rod 31, and first connecting rod 31 is hinged with slide bar 9; Slide bar 9 is sleeved on the sleeve 5; Slide bar 9 external part two ends are an end of hinged two second connecting rods 32 respectively, and an end of the bar part of two effect pincers 4 is fixedly hinged at the two ends of sleeve 5 external parts, and the pliers part of effect pincers 4 is hinged with the other end of two second connecting rods 32 respectively.When rocking bar 8 was lifted, first connecting rod 31 drove stretching out of slide bar 9, because second connecting rod 32 is hinged with slide bar 9 external parts, therefore, effect pincers 4 can be strutted; When rocking bar 8 was depressed, first connecting rod 31 drove the indentation of slide bars 9, thereby by the effect of second connecting rod 32, will act on and clamp 4 closures, thus gripping foreign material easily.
On sleeve 5 and driving mechanism 1, all press jug 10 simultaneously, the design of ergonomic can make the staff be more convenient for putting forth effort, and makes that drawing pincers clearly opens with closed fast.
With above-mentioned desirable embodiment according to the utility model is enlightenment, and through above-mentioned description, the related work personnel can carry out various change and modification fully in the scope that does not depart from this utility model technological thought.The technical scope of this utility model is not limited to the content on the manual, must confirm its technical scope according to the claim scope.
