Detailed description of the invention
For making the technical solution of the utility model clearer, the utility model is described in further detail for specific embodiment below in conjunction with the accompanying drawings.
As shown in Figure 1-2, the sub-spanner of multiplex inner connecting tube, it is made up of sleeve 1, screw rod 2, handle 3 and push rod 5；Push rod 5 is inserted in inside the other end of sleeve 1, and is connected to the outside of sleeve 1 by spring 7, is equipped with a latch 14 above the position that sleeve 1 and push rod 5 contact；Screw rod 2 is partially installed on inside one end of sleeve 1, is additionally provided with steel ball 6 between screw rod 2 and sleeve 1；Handle 3 is movably connected in the bottom of sleeve 1；The outside of sleeve 1 is additionally provided with cover plate 4.
As shown in Figure 3-4, one end of sleeve 1 is the mouth of pipe 11, and the mouth of pipe 11 is internal for setting threaded bobbin 10, is used for inserting screw rod 2；The bottom of sleeve 1 is provided with connecting portion 12, is used for being flexibly connected handle 3；The two ends, outside of sleeve 1 are equipped with a screw 13, are used for installing cover plate 4；The other end of sleeve 1 is arranged over left latch 140.Being respectively equipped with groove 15, projection 16 and groove 17 between two screws 13, its further groove 17 is positioned at groove 15 and the centre of projection 16, and projection 16 has projection perforation 161, and projection perforation 161 is connected with one end of spring 7.
As seen in figs. 5-6, the most external of one end that sleeve 1 has left latch 140 is external port 18, and external port 18 connects the bellmouth 19 inwardly become narrow gradually, and the other end of bellmouth 19 is connected with bobbin 10.Push rod 5 can be inserted sleeve 1 from external port 18 when installing push rod 5, owing to external port 18 is relatively big, and become narrow gradually inward through bellmouth 19, successfully push rod 5 can be put into sleeve 1.
As it is shown in fig. 7, latch 14 is provided with multiple teeth 142, the cusp angle of the whole tooth form of silk tooth 142 is 55 degree or 60 degree, and tooth spacing is per inch 11 tooth or 14 teeth.Silk tooth 142 has three kinds, top outermost is a first type tooth 1421, first type tooth 1421 is 1/3rd of the whole tooth form of silk tooth 142, inwardly there is a Second-Type tooth 1422, Second-Type tooth 1422 is 2/3rds of the whole tooth form of silk tooth 142, other are the 3rd type tooth 1423, and the 3rd type tooth 1423 is whole tooth form.
As shown in Figure 8, screw rod 2 includes head 21 and shaft 22, and on shaft 22, the one end away from head 21 is provided with end 23, and end 23, in open out shape, is used for connecting spring 7.
As shown in figs. 9-10, one end of push rod 5 is fixed with the top 53 of closing, top 53 be fixedly arranged above right latch 141, the other end is provided with rod aperture 56, the outside of push rod 5 is provided with fixture block 51, and fixture block 51 has fixture block perforation 52, and fixture block perforation 52 is connected with one end of spring 7.
As shown in figure 11, top 53 can also is that and is detachably connected on push rod 5, and rod aperture 56 runs through top 53.
When using bulldog wrench, first move push rod 5, make top 53 touch sleeve 1, left latch 140 and right latch 141 are merged；Then open and hold handle 3, two latches 14 are stretched into inside broken end pipe to be operated, it is enclosed within the head 21 of screw rod 2 with spanner and rotates, by screw rod 21 to the internal motion of sleeve 1, now end 23 can oppress the rod aperture 56 of push rod 5 by steel ball 6, promote push rod 5, two latches 14 are caused to separate, until left latch 140 and right latch 141 block the inwall both sides of broken end pipe respectively, existence due to silk tooth 142, relatively big or with tube interior the screw thread that rubs between latch 14 and pipe fastens, and connects the tightst；Pulling handle 3, i.e. can be taken off joint or the corrugated tubing of inwall residual of broken end pipe.
If the inside of pipe has screw thread and because corrosion or grime cause screw thread to lose effect, it is also possible to the turne tube spanner when inserting latch 14, use silk tooth 142 to process the screw thread of inwall, i.e. carry out tapping.The first type tooth 1421, Second-Type tooth 1422 and 1,423 3 kinds of different types of teeth of the 3rd type tooth are used to carry out tapping in order, it is possible to effectively to carve screw thread at tube wall, for the operation such as the taking-up of pipe or installation.
The rotation direction of silk tooth 142 can be left-handed or dextrorotation, when dismantling pipe, in order to engage smoothly, it should select the bulldog wrench that silk tooth 142 is oppositely oriented with IPT；And when carrying out tapping, then should select the bulldog wrench that a tooth 142 is identical with IPT rotation direction.
As illustrated by figs. 12-13, the bulldog wrench in this utility model can be to be applicable to the pipe of various different inner diameters, of many uses by the distance between two latches 14 of regulation, easy to operate, practical.
The foregoing is only detailed description of the invention of the present utility model; but protection domain of the present utility model is not limited thereto; any those familiar with the art is in the technical scope that this utility model discloses; change or the technical scheme replaced can be readily occurred in, all should contain within protection domain of the present utility model.
