Description

Clamp type F folder

Technical field

The utility model relates to a kind of anchor clamps, and particularly a kind of clamp type F folder belongs to the clamping device field.

Background technology

Usually the clamp type F folder of producing on the existing market, history has for many years been arranged, this F folder is made up of parts such as retaining clip, movable clamp, screw mandrel, expansion bearing seat, handle, rivet, slide bar, clamp, springs, screw mandrel and handle are fixed the movable clamp of back screw-in with rivet, the expansion bearing cover for seat is gone on the spherosome of one of screw mandrel, retaining clip is inserted in slide bar to be fixed with rivet, is inserted in slide bar after putting into clamp and spring in the live splint body cavity.But the clamp of this clamp type F folder is shorter, unclamp the clamp inconvenience, and effort, does not have length dimension on the slide bar, does not know clamping length.

Summary of the invention

The deficiency that the utility model exists at prior art is improved on the basis of existing clamp type F folder, and a kind of novel clamp type F folder is provided, it is convenient and strength-saving to make it unclamp clamp, can know clamping length, increase clamp intensity, hold the handle rotation and be difficult for skidding.

The utility model realizes that by following scheme the utility model comprises: retaining clip, clamp sheath, supporting base sheath, expansion bearing seat, movable clamp, screw mandrel, cuff, handle, handle bonnet, slide bar, stub plate, long clamp, spring, handle capping.Screw mandrel and handle are fixed the movable clamp of back screw-in with cuff and handle rivet, and the expansion bearing cover for seat is gone on spherosome of screw mandrel, and retaining clip is inserted in slide bar to be fixed with the retaining clip rivet.Concrete improvement is as follows:

Curve an angle parallel behind the long clamp afterbody lengthening, upwards pull the interlock that just can unclamp with slide bar, movable clamp is moved arbitrarily on slide bar with screw mandrel.Stamp the length scale on the slide bar, can know holding workpiece length.Retaining clip and movable clamp have added the diagonal brace muscle, make clamp increase intensity.Handle axis is hollow to the centre, and the profile section is a hexagon, and an end has a circular hole for allocating screw mandrel usefulness into, and the other end is mixed capping, because handle profile hexagon is difficult for skidding so hold the handle rotation.The live splint intracoelomic cavity is provided with stub plate, long clamp, spring, is inserted in slide bar and can be locked on the slide bar, during holding workpiece, movable clamp is not fallen back.In the middle of the screw mandrel is T type screw thread, and an end is a cylinder, uses for allocating handle into; The other end is a spherosome, uses for allocating the expansion bearing seat into.Expansion bearing seat one end has a circular hole, is inserted in the screw mandrel spherosome, receives the small sircle hole oral area again, makes the expansion bearing seat can not skid off spherosome.During use, earlier movable clamp is moved to the workpiece that needs clamping, by the handle rotary screw rod holding workpiece of advancing, workpiece is unclamped in counter-rotating again, and long clamp makes progress and cockedly just can move movable clamp.

The utility model is simple in structure, and is easy to operate, and long clamp just rises and can move movable clamp arbitrarily to upper plate, and length dimension is arranged on the slide bar, so can know clamping length.

The specific embodiment

As shown in Figure 1, the utility model comprises: retaining clip 1, clamp sheath 2, supporting base sheath 3, expansion bearing seat 4, movable clamp 5, screw mandrel 6, cuff 7, handle rivet 8, handle 9, handle bonnet 10, retaining clip rivet 11, slide bar 12, stub plate 13, long clamp 14, spring 15, handle capping 16.Wherein, screw mandrel 6 is fixed in movable clamp 5 screwed holes of back screw-ins with handle 9 usefulness cuffs 7 and handle rivet 8, handle 9 is allocated in handle capping 16 into, handle bonnet 10 is allocated handle capping 16 into, it is fixing that retaining clip 1 is inserted in slide bar 12 usefulness retaining clip rivets 11, retaining clip 1 head is inserted in clamp sheath 2, and expansion bearing seat 4 is inserted in supporting base sheath 3.

Concrete improve as follows: curve an angle parallel after long clamp 14 afterbodys extend, stamp the length scale on the slide bar 12 with screw mandrel 6.Retaining clip 1 and movable clamp 5 have increased the diagonal brace muscle on clamp, T type screwed hole is arranged at movable clamp 5 tops, are provided with stub plate 13 long clamp 14 and springs 15 in the lower chamber, and an oblong aperture is arranged at stub plate 13, long clamp 14 bottoms, is inserted in slide bar 12 by oblong aperture.Handle 9 is axially middle to be hollow, and the profile section is a hexagon, and an end is mixed handle capping 16 and handle bonnet 10.In the middle of the screw mandrel 6 is T type screw thread, and an end is that cylinder is allocated handle 9 usefulness into, and the other end is that spherosome is allocated expansion bearing seat 4 usefulness into.Expansion bearing seat 4 small ends have a circular hole to be inserted in screw mandrel 6 spherosomes and receive little oral area, and big end is a circular flat, and cover upper branching holder sheath 3 can prevent to crush workpiece.Retaining clip 1 top is a plane, and cover upper clamp sheath 2 can prevent to crush workpiece.

When screw mandrel 6 rotated, the ball physical efficiency of screw mandrel 6 heads was rotated in the hole of expansion bearing seat 4 flexibly, and promotion expansion bearing seat 4 advances or retreats.Movable clamp 5 utilizes spring 15 push-tight stub plates 13 and long clamp 14 fastenings at slide bar 12, and its movable clamp 5 when clamping is worked can outwards not slided.Owing to curve an angle parallel behind the long clamp 14 afterbodys lengthening,, just can unclamp the fastening of stub plate 13 and long clamp 14 and slide bar 12, so more convenient laborsaving as long as upwards pull long clamp 14 afterbodys with screw mandrel 6.Stamp the length scale on the slide bar 12, can know the length of holding workpiece.Increased the diagonal brace muscle on two clamps of retaining clip 1 and movable clamp 5, so increased the intensity of two clamps.Because handle 9 profile hexagons are difficult for skidding so hold handle 9 rotations.
