Telescopic multifunctional picks thing pincers
Technical field
The utility model relates to a kind of clamping device, particularly relates to a kind of telescopic multifunctional and picks thing pincers.
Background technology
What cleanup crew used now has chuck, and can opening and closing pick thing pincers be that there is a chuck, chuck junction is active to be connected, junction is provided with pull bar, pull bar is have cotton rope, cotton rope is connected by the squeezing handle passed in expansion link with on hand holding handle, and squeezing handle has a gland and an opening and closing handle, and cotton rope and opening and closing are being connected.By pinching opening and closing handle, pull cotton rope, drive pull bar to move upward, thus chuck is closed, bottom surface object is clamped.This kind of structure pick thing pincers when adjustable telescopic rod length, the connection of need to get loose cotton rope and opening and closing handle, after expansion link is adjusted to the right place, then cotton rope and opening and closing handle are fixed.Each adjustment is comparatively time-consuming, and when daily cleaning, needs frequent adjustable telescopic rod length, comparatively inconvenience.
Summary of the invention
The purpose of this utility model is to propose a kind ofly the telescopic multifunctional of quick adjustment length of telescopic bar to pick thing pincers.
The purpose of this utility model is achieved in that telescopic multifunctional picks thing and clamps it and comprise mobile jib, mobile jib upper end installing hand holding handle, hand holding handle side installing squeezing handle, in mobile jib, stretch into main drawing line, main drawing line upper end is connected with the opening and closing handle of squeezing handle through the gland of squeezing handle.Be inserted with secondary bar in mobile jib bottom, mobile jib offers locating hole, secondary bar is equiped with the hoodle corresponding with locating hole, hoodle and locating hole clamping.Connect grip slipper in secondary bar lower end, have an arc notch in described grip slipper, in arc notch, be equiped with symmetrical chuck, described two chuck junctions are equiped with back-moving spring and connecting rod, and connecting rod upper end is stretched in secondary bar.Connecting rod is have secondary stay, major and minor bracing wire is connected with bracing wire take-up.Described bracing wire take-up comprises contiguous block, laterally offers clamping hole, be placed with pilot pin, offer main drawing line hole in side, contiguous block upper surface in clamping hole in contiguous block, offers symmetrical secondary stay hole at the upper and lower end face of contiguous block opposite side.Described main drawing line is connected with pilot pin, and secondary stay is passed by secondary stay hole.
Owing to implementing technique scheme, the utility model can regulate major and minor pole length fast, easily, and adjustment process is without the need to loosening main drawing line, only need when squeezing handle not be mediated, carry out secondary bar adjustment, can integral telescopic be completed, be suitable for using when frequently regulating length.

Detailed description of the invention:
The utility model by the restriction of following embodiment, can not determine concrete embodiment according to the technical solution of the utility model and actual conditions.
Embodiment: as shown in Figure 1, telescopic multifunctional picks thing and clamps it and comprise mobile jib 1, mobile jib 1 upper end installing hand holding handle, and hand holding handle side installing squeezing handle, in mobile jib 1, stretch into main drawing line 3, main drawing line 3 upper end is connected with the opening and closing handle of squeezing handle through the gland of squeezing handle.Be inserted with secondary bar 7 in mobile jib 1 bottom, mobile jib 1 offers locating hole, secondary bar 7 is equiped with the hoodle 2 corresponding with locating hole, hoodle 2 and locating hole clamping.Connect grip slipper 9 in secondary bar 7 lower end, have an arc notch 10 in described grip slipper 9, in arc notch 10, be equiped with symmetrical chuck 12, described two chuck 12 junctions are equiped with back-moving spring 11 and connecting rod 8, and connecting rod 8 upper end is stretched in secondary bar 7.Connecting rod 8 is have secondary stay 6, major and minor bracing wire 3,6 is connected with bracing wire take-up.Described bracing wire take-up comprises contiguous block 4, laterally clamping hole 15 is offered in contiguous block 4, be placed with pilot pin 5 in clamping hole 15, offer main drawing line hole 13 in side, contiguous block 4 upper surface, offer symmetrical secondary stay hole 14 at the upper and lower end face of contiguous block 4 opposite side.Described main drawing line 3 is connected with pilot pin 5, and secondary stay 6 is passed by secondary stay hole 14.
Described secondary stay 6 length is greater than secondary pole length.
Described clamping hole 15 is up-small and down-big water-drop-shaped hole, also namely its have one little one large two respectively to upper arc tips outstanding downwards, waist is also curved portions outwardly.Upper and lower part and the waist in described clamping hole 15 cross section are arc, and top camber line curvature is maximum, and waist takes second place, and bottom camber line curvature is minimum.Described pilot pin 5 is cylinder, also can be identical with clamping hole 15 cross sectional shape, i.e. upper and lower part and identical rectangular of waist curvature.
In use, by pinching squeezing handle, drive main drawing line 3 to promote, drive pilot pin 5 to promote, pilot pin 5 is until contact with the little arc tips inwall in clamping hole 15 top simultaneously, now by stuck for secondary stay 6, drive secondary stay 6 to promote simultaneously, thus drive connecting rod 8 to promote, chuck 12 is moved in arc notch 10, chuck 12 closes, and gets final product gripping objects.
When needs adjust major and minor bar 1,7 length, unclamp squeezing handle, main drawing line 3 and pilot pin 5 sagging, pilot pin 5 and clamping hole 15 inwall get loose, cannot stuck secondary stay 6, now i.e. adjustable major and minor bar 1,7 length.Because secondary stay 6 length is much larger than secondary bar 7 length, therefore secondary bar 7 stretches out secondary stay 6 at utmost also can not be caused to come off by contiguous block, therefore after adjustment, still can with main drawing line 3 acting in conjunction, drive chuck 12 to close.
According to service condition, chuck 12 can being replaced by the cutting head with putting the first edge on a knife or a pair of scissors, driving major and minor bracing wire 3,6 by pinching squeezing handle, thus drive cutting head to carry out shear action.Described cutting head its there is the cut part of two lobe symmetries, two cut part counterparts are put the first edge on a knife or a pair of scissors, and upper end is connected, and connecting place installing back-moving spring, cutting head connecting portion is in the arc notch 10 of clamping part 9.
Above technical characteristic constitutes most preferred embodiment of the present utility model, and it has stronger adaptability and best implementation result, can increase and decrease inessential technical characteristic according to actual needs, meet the needs of different situations.
