There is a sliding clencher for expand tube and tension function, comprise sliding clencher, described sliding clencher is provided with self-mountable & dismountuble pipe-expanding device.This kind of sliding clencher realizes to carry out expand tube, hole expansion function to pipeline very easily on the basis of same sliding clencher by installing self-mountable & dismountuble pipe-expanding device on the basis of original sliding clencher, completing the pipeline after reaming just can utilize sliding clencher to connect another pipeline or joint very easily, not only avoid the technology drawback that interference fit cannot access, and realization cunning is on the same device tight, expand tube dual-use function substantially increases joint efficiency and quality.
The flexible handle that the fixed handle that is fixedly connected with sliding clencher body clamps and be flexibly connected is comprised as the sliding clencher described in concrete structure, in sliding clencher body, gear steps bar is installed, tooth bar is provided with on the downside of gear steps bar, tooth bar has been connected with a joggle shifting block, shifting block connects flexible handle by Compress Spring, and driven wheel stepping bar advances.Described flexible handle side connects sliding clencher body by extension spring.This kind of sliding clencher drives shifting block by flexible handle, driven wheel stepping bar advances, flexible handle is pulled the bar of driven wheel stepping and to be advanced a tooth, then reset under the extension spring effect of flexible handle side, realize next driving to circulate, the final gear steps bar that constantly promotes advances, and the pipeline that realization is arranged on sliding clencher or joint are interconnected.
Tooth bar on the downside of described gear steps bar is also connected with retreat stop block, and on rear side of retreat stop block, apical grafting is installed on the screw on sliding clencher body.This kind of technical pattern effectively prevent pipeline or joint is interconnected reaction force powerful in process, and the gear steps bar caused retreats problem.
Described self-mountable & dismountuble pipe-expanding device comprises the pipe-expanding device body be connected with sliding clencher, and pipe-expanding device body is provided with expand tube head, is provided with push rod in expand tube head, push rod tail end is fixedly connected with push pedal by screw.Described pipe-expanding device body is provided with groove and is fastened and connected sliding clencher body; Bottom described push pedal, contact connects gear steps bar.This kind of pipe-expanding device is fixed on sliding clencher body by body relatively, and push rod connects gear steps bar by push pedal, realize push rod thus to travel forward relative to pipe-expanding device body, reach the technical purpose opening expand tube head, realize the pipe diameter be placed on expand tube head to expand, reach expand tube object.Here pyramidal structure that yes its end of push rod, be convenient to gradually open expand tube head.
Pipe-expanding device body is connected by fixing Limit screw as the push pedal described in preferred structure; The back-moving spring being placed on push rod periphery is also provided with between described push pedal and pipe-expanding device body.This kind of technical pattern connects pipe-expanding device body by fixing Limit screw and limits the extreme position of push pedal in reseting procedure, and offsetting spring structure good achieve the reset function of push pedal after push rod completes expand tube, the circulation being convenient to next expand tube starts.
In order to realize the positioning performance for carrying out pipeline or the joint connected, gear steps masthead end is provided with bearing pin.
The utility model realizes to carry out expand tube, hole expansion function to pipeline very easily on the basis of same sliding clencher by installing self-mountable & dismountuble pipe-expanding device on the basis of original sliding clencher, completing the pipeline after reaming just can utilize sliding clencher to connect another pipeline or joint very easily, not only avoid the technology drawback that interference fit cannot access, and realization cunning is on the same device tight, expand tube dual-use function substantially increases joint efficiency and quality.
Accompanying drawing explanation
Be illustrated in figure 1 the sliding clencher master that the utility model has expand tube and a tension function and look sectional structure schematic diagram.
Detailed description of the invention
There is a sliding clencher for expand tube and tension function as shown in Figure 1, comprise sliding clencher, sliding clencher is provided with self-mountable & dismountuble pipe-expanding device.
Sliding clencher comprises the flexible handle 12 that the fixed handle that is fixedly connected with sliding clencher body 17 clamps 13 and is flexibly connected, in sliding clencher body 17, gear steps bar 7 is installed, tooth bar is provided with on the downside of gear steps bar 7, tooth bar has been connected with a joggle shifting block 10, shifting block 10 connects flexible handle 12 by Compress Spring 11, driven wheel stepping bar 7 advances, and realizes connecting for the interference fit between two pipelines be arranged on sliding clencher or joint, namely sliding stressed joint.Shell structure is in order to reduce manufacturing cost and weight of equipment flexible handle 12 and fixed handle pincers 13.Flexible handle 12 side connects sliding clencher body 17 by extension spring 16, realizes the reset function of flexible handle 12.
