Water pump clamp convenient to maintain and manufacturing process thereof

Abstract

The water pump pliers convenient to maintain comprise a first clamping arm and a second clamping arm, a mounting groove is formed in the second clamping arm, the first clamping arm is mounted in the mounting groove, a first clamping head is arranged at the head end of the first clamping arm, and a second clamping head is arranged at the head end of the second clamping arm; the first clamping head corresponds to the second clamping head. The first clamping plate is arranged in the first clamping head, the second clamping plate is arranged in the second clamping head, the first clamping plate and the second clamping plate are the same in structure, the fixing grooves are formed in the first clamping plate and the second clamping plate, and the spring columns are arranged in the fixing grooves; the clamping columns are arranged on the side faces of the spring columns, the clamping columns are in telescopic connection with the fixing grooves through the spring columns, the conical heads are arranged at the head ends of the clamping columns, the clamping shape can be automatically changed according to the shape of a clamped pipeline, therefore, the pipelines of different shapes can be clamped, and the clamping stability of the pipeline clamping device is guaranteed.

Description

technical field [0001] The invention relates to the technical field of water pump pliers, in particular to a water pump pliers that are easy to maintain and a manufacturing process thereof. Background technique [0002] Water pump wrench works like a pipe wrench. However, it is lighter, smaller and easier to use than the pipe wrench. Generally, it is more suitable for household non-professional emergency or simple installation of water pipes. Of course, the clamping force is not as good as the pipe wrench; it is used to clamp flat or cylindrical metal parts. It is characterized by jaws The opening width has multiple levels (three to four levels) to adjust the position to meet the needs of holding parts of different sizes. It is a commonly used tool in the installation and maintenance of automobiles, internal combustion engines, agricultural machinery and indoor pipelines. [0003] At present, the structure of the existing water pump pliers is fixed, and it is impossible to ...
