[0002] Before the cables are put into use, they need to undergo a bending durability test and can only be put into use after meeting the standards. When the existing cable bending durability testing device is in use, the cables and the device are mainly fixed by cable ties, which are not only easy to loosen, but also need to be cut and thrown away after the test, resulting in waste of cable ties. In addition, the cables move back and forth during the bending durability test, and the cable surface will rub against the device, which is easy to cause damage to the cable surface and affect its use. In order to solve the above problems, a wire harness bending durability test tooling is needed.

[0010] Preferably, the fixing plate is threadedly connected to the cross frame via a fixing shaft, and the limiting sleeve is symmetrically arranged with the central axis of the fixing plate as the center.

[0011] Preferably, the anti-wear mechanism comprises a positioning sleeve, a rotating shaft and a rubber roller, the side wall of the device body is installed with the positioning sleeve, the inner wall of the positioning sleeve is installed with the rotating shaft, and the outer wall of the rotating shaft is installed with the rubber roller.

[0012] Preferably, the positioning sleeve is movably connected to the rotating shaft, and the rotating shaft is sleeve-connected to the rubber roller.

[0013] Compared with the prior art, the beneficial effects of the utility model are:

[0014] 1. The utility model sets a limiting mechanism, the fixing plate is fixed to the cross frame by a fixing shaft and a thread, and the limiting sleeve is symmetrically arranged with the central axis of the fixing plate as the center. When using the device, firstly, one end of the cable is passed through the interior of the positioning plate, and then the other end of the cable is inserted into the interior of the limiting sleeve, and then the limiting shaft is rotated to fix the cable with the limiting sleeve.

[0015] 2. The utility model has an anti-wear mechanism, in which the positioning sleeve and the rotating shaft are movably connected, and the rotating shaft and the rubber roller are sleeved. When the device is in use, the rubber roller fits tightly against the surface of the cable to be tested. When the transmission motor drives the cross frame to move back and forth, the cable will rub against the outer wall of the device body, which will easily wear out the surface of the cable. The rubber roller and the rotating shaft are movably connected, and when the cable reciprocates left and right, the rubber roller will slide accordingly. The rubber roller and the cable are in a relatively static state, which reduces the wear on the cable surface.
