Hollow bolt with repeatable dismounting a-shaped quick connector and processing detection device thereof Technical Field The application relates to the field of bolt detection, in particular to a hollow bolt with a repeatable dismounting type a quick connector and a processing detection device thereof. Background At present, an efficient pipeline connecting part of an a-type quick connector hollow bolt is widely applied to the fields of hydraulic transmission systems, pneumatic control systems, automobile manufacturing, engineering machinery, aerospace and the like. The device is especially suitable for fluid pipeline connection occasions requiring frequent assembly and disassembly or limited space by virtue of the characteristics of compact structure, rapid connection, reliable sealing and the like. The hollow bolt in the prior art generally comprises a threaded base, a sealing ring sleeved outside the threaded base, a fixing ring clamped at the top of the threaded base and a clamping ring arranged inside the fixing ring, wherein the clamping ring comprises a clamping part movably abutted with a pipeline and an abutting part positioned in the fixing ring. When a technician installs a pipe, the pipe is first inserted from one end of the hollow bolt so that it passes through the inner hole of the bolt base, and then the reducing nut is screwed into the externally threaded portion of the bolt base. Along with the continuous tightening of the nut, the conical inner wall of the nut can apply radial inward pressing force to the fixing ring, and the force is transmitted to the clamping ring inside to promote the clamping ring to radially shrink, so that the clamping ring is tightly meshed on the outer wall of the pipeline, and the fastening and sealing between the pipeline and the joint are realized. In the prior art, a mechanical drawing device is generally used for testing the connection strength of the hollow bolt, and the clamping strength of the clamping ring is judged through the tensile force value on the tension sensor inside the identification device. However, in the prior art, when a pull test is performed on pipes of different specifications to determine the connection strength between the hollow bolts and the pipes, it is generally necessary to replace the hollow bolts with different snap ring groups to perform the test one by one, so as to evaluate the locking effect under different snap ring configurations. Meanwhile, the connection tightness between each group of hollow bolts and the pipeline is detected, and the connection strength and the sealing performance of the hollow bolts are comprehensively compared, so that the hollow bolts matched with the target pipeline are screened out. The test mode is complex in operation, long in test period and difficult to determine the optimal bolt configuration scheme efficiently and accurately, so that improvement is needed. Disclosure of Invention In order to solve the problems that existing equipment is complicated in process of detecting hollow bolts matched with pipelines of different specifications and low in efficiency, the application provides a repeatable-disassembly type a quick-connection hollow bolt and a machining detection device thereof. The application provides a hollow bolt with a type a quick connector capable of being repeatedly disassembled and assembled and a processing and detecting device thereof, which adopts the following technical scheme: The utility model provides a but processing of repeated dismouting a type quick connector hollow bolt detection device includes the organism, be provided with the grip disc on the organism, the slip is provided with the mounting panel on the organism, be provided with on the mounting panel and be used for detecting the snap ring group is counted first detection subassembly that influences to pipeline joint intensity, be provided with and be used for detecting the second detection subassembly that snap ring length influences to pipeline joint intensity, be provided with be used for test pipeline with hollow bolt tensile strength's drawing subassembly and be provided with be used for detecting the pipeline with sealing component between the hollow bolt. Through adopting above-mentioned technical scheme, because the length of snap ring and the butt area of snap ring and pipeline will directly influence the radial pressure that the snap ring applyed the pipeline, and the snap ring is at the fastening in-process, probably arouse pipeline plastic deformation, lead to there is the clearance between pipeline and the hollow bolt, and then reduce the leakproofness of pipeline junction, influence pipeline normal use, and when carrying out the experiment through drawing equipment among the prior art, need change different hollow spiral and detect, and detect the leakproofness of different hollow bolt simultaneously, ensure hollow bolt's connectivity and sealing performance. When detecting pipelines with different
