Description

Portable puller Technical Field The utility model relates to the technical field of valve seat extractors, in particular to a portable puller. Background At present, when a valve seat needs to be taken out in a construction site, a method of pushing the valve seat by a pry bar against the bottom of the valve seat and hammering the pry bar is generally adopted to push the valve seat out, and the method is time-consuming and labor-consuming and is easy to damage a valve box. For this reason, the present company has proposed a patent product with publication number CN217394844U to solve the above-mentioned problems. However, in practical application, the valve seat is arranged at the suction end and the discharge end of the valve box, so that the integrated rod body is longer when the valve seat at the suction end is pulled out, most of the rod body needs to be exposed outside the valve box in the pulling-out process, and the lifting stroke of the lifting assembly is overlarge due to the longer rod body. Disclosure of utility model The utility model aims to provide a portable puller so as to solve the problems in the background art. The portable puller comprises a jacking component, wherein a connecting rod assembly is further arranged in the jacking component, one end of the connecting rod assembly penetrates through the jacking component and then is connected with a nut, the other end of the connecting rod assembly is connected with a tensioning sleeve assembly, the connecting rod assembly comprises a first rod body and a second rod body, and the first rod body is movably connected with the second rod body. According to the preferred technical scheme, one end of the first rod body is movably connected with a connecting part arranged on the second rod body through a connecting rod. As the preferable technical scheme of the utility model, the connecting rod is an external thread column and is connected with the internal thread arranged on the inner wall surface of the connecting part in an adaptive manner. According to the preferable technical scheme, one end of the second rod body, which is far away from the connecting part, is in threaded fit with the inner wall surface of the tensioning sleeve assembly through the first external threads. As a preferable technical scheme of the utility model, one end of the first rod body is provided with a second external thread, and the other end of the first rod body is provided with a third external thread. By adopting the technical scheme, the valve seat has the advantages that the valve seat is stable and quick in taking out process, the valve box is not easy to damage, the replacement efficiency of the valve seat is improved, particularly, the connecting rod assembly is of a split structure, so that the first rod body is used when the valve seat at the suction end is taken out, the two rod bodies are connected together when the valve seat at the discharge end is taken out, the problem that the length of the integral rod body extending out of the valve box is overlarge when the valve seat at the suction end is taken out is effectively solved, and the problems that the space occupied by the rod bodies is large and the integral rod body is inconvenient to carry and transport are solved.
