Embodiment Construction
[0008] In the figure, a portable manual pipe bender mainly includes three parts: spring (1), handle (2) and rubber sleeve (3). It is an integral special-shaped spring structure. The middle part of the spring (1) is cylindrical, with The size is equal to the outer diameter of the water pipe, the two ends are handles (2), which are funnel-shaped springs, and the funnel spring is flattened to form a flat funnel mouth structure; the handle (2) is equipped with a rubber sleeve ( 3), convenient to hold by hand during operation. When bending the water pipe, put the special-shaped spring (1) of the pipe bender on the outside of the water pipe, hold the rubber sleeves (3) at both ends with both hands, and bend the water pipe to the required angle. After the water pipe bending operation is completed, pull out the pipe bender along the water pipe That is, the flat funnel mouth structure at both ends of the pipe bender facilitates the exit of the pipe bender from the water pipe.

A portable hand-operated pipe bender mainly comprises a spring (1), handles (2) and rubber sleeves (3), and is a whole abnormity spring structure; the middle portion of the spring (1) is cylindrical, wherein the inner diameter size equals to a water pipe outer diameter size; two end handles are funnel shape springs, and are flattened to form flat funnel port structures; the handles are provided with easy handling rubber sleeves (3), so the bender can be conveniently held in operation; in application of bending the water pipe, the water pipe is sleeved by the bender abnormity spring (1), the rubber sleeves (3) on two ends are held by hands so as to bend the water pipe to a needed angle; when the water pipe bending work is finished, the bender can be pulled out along the water pipe; the flat funnel port structures on two ends of the bender allow the bender to be easily pulled from the water pipe; the beneficial effects are that the portable bender is simple and reliable in structure, portable, convenient in operation, can effectively protect the water pipe in water pipe bending work, thus preventing the water pipe from being flattened or even damaged.
Description
Technical field [0001] The invention relates to a portable manual pipe bender, which is suitable for convenient bending and protection of water pipes during plumbing installation. Background technique [0002] Aluminum-plastic pipes and plastic pipes are more and more widely used. When installing water pipes, it is often necessary to bend the water pipes. However, since there are no practical tools to protect the water pipes, the water pipes are often flattened or even ruptured due to excessive bending angles, causing the service life of the entire water pipe to decrease or even be scrapped. In order not to flatten or break the water pipe when it is bent, a simple and portable manual pipe bender is very much needed. Contents of the invention [0003] The object of the present invention is to solve the above problems, to provide a simple structure, portable, easy to operate, to realize the safety protection of the water pipe during the bending operation of the water pipe, ...
