Detailed description of the invention
In order to make those skilled in the art understand the technical solution of the utility model better, below in conjunction with specific embodiment this programme being done and introducing in detail further.
As depicted in figs. 1 and 2, the wiper arm extracting tool that the utility model provides, comprises force application rod 1, threaded mandrel 2, crossbeam 3, and described force application rod 1 is fixed on the top of described threaded mandrel 2, described threaded mandrel 2 passes the screwed hole on described crossbeam 3, with described crossbeam 3 threaded engagement; Described crossbeam 3 is also provided with the first drag hook 4 and the second drag hook 5, described first drag hook 4 and described second drag hook 5 are placed in the both sides of described threaded mandrel 2, and are fixed on slidably on described crossbeam 3.
As shown in Figure 3, during dismounting wiper arm, first distance between the first drag hook 4 and the second drag hook 5 is adjusted to suitable position, then drag hook is made by wiper arm 8 by tight, and the working face of wiper arm lower plane and drag hook is adjacent to, or else disconnected rotation force application rod 1, makes threaded mandrel 2 hold out against windscreen wiper output shaft 9, until wiper arm 8 is removed.This extracting tool structure is simple, and convenient operation, threadedly transmitting forces, can reduce the removal force of wiper arm, for convenience detach, and is unlikely to the modular construction damaging windscreen wiper system.
On the basis of the utility model technique scheme, described wiper arm extracting tool also can comprise adjustment screw mandrel 6, described adjustment screw mandrel 6 is successively through described first drag hook 4 and described second drag hook 5, and one end of described adjustment screw mandrel 6 is provided with spacing termination, through after described first drag hook 4 or described second drag hook 5 and its clamping, the other end is fixed by adjusting nut 7 and described first drag hook 4 or described second drag hook 5, described adjustment screw mandrel 6 can ensure that tool holder wiper arm does not loosen, and prevents drag hook slippage in the process of dismounting.
