The specific embodiment

Below in conjunction with accompanying drawing, the utility model is elaborated.

As shown in Figure 1-2, a kind of pipeline strainer, comprise housing 4, flexible handle 1, square bar 6, front end draw-in groove 5, rear end draw-in groove 7, be arranged on gear 2, the front ratchet 9 of housing 4 inside, rear ratchet 3, flexible handle is flexibly connected with the gear 2 of housing 4 inside by rear ratchet 3, front ratchet 9 is connected with housing 4 afterbodys, one end of housing is provided with front end draw-in groove 5, between housing 4 and front end draw-in groove 5 for being fixedly connected with, the afterbody of square bar 6 is provided with rear end draw-in groove 7, and square bar top is provided with tooth bar 8, gear 2 and tooth bar 8 phase interlocks.

The course of work of this example: when starting to operate, strainer is adjusted to stretchable maximum position, clockwise rotate flexible handle 1, rotate by rear ratchet 3 driven gears 2, housing 4 and front end draw-in groove 5 are moved right, complete the process of once straining; When regaining tension space, rotate counterclockwise flexible handle 1, rear ratchet 3 exits, and front ratchet 9 blocks gear 2, and gear 2 remains static, and repeats tension process, thereby reaches final effect.

Above an embodiment of the present utility model is had been described in detail, but described content is only preferred embodiment of the present utility model, can not be considered to for limiting practical range of the present utility model.All equalization variations of doing according to the utility model application range and improvement etc., within all should still belonging to patent covering scope of the present utility model.
