Abstract

The invention discloses an unplugging assisting device. The unplugging assisting device comprises a rotatable base rod (300), a handle (400), a sliding rod (500), a shake-prevention clamping part (600) and a spring washer (700). A bayonet (310) and a mounting hole (320) of the shake-prevention clamping part are formed in one end of the rotatable base rod (300). A cross beam (330) is sleeved with the sliding rod (500), and the sliding rod (500) can slide on the cross beam in the axial direction in a reciprocated mode. A cylindrical protruding block (610) is arranged on the shake-prevention clamping part (600), an inner hole (611) of the protruding block is a mounting hole of a PCB (900), and the whole device is mounted and fixed to the PCB (900) through the hole by means of a screw (800). The columnar outer edge (612) of the protruding block is used for mounting the whole shake-prevention clamping part (600) on the rotatable base rod (300). The columnar outer edge (612) of the protruding block is further sleeved with the spring washer (700) so as to eliminate a gap between the shake-prevention clamping part (600) and the rotatable base rod (300). The unplugging assisting device can be prevented from shaking, and is firm in structure, reliable to use and capable of being mounted and dismounted easily and conveniently.

Description

technical field [0001] The invention relates to an auxiliary tool for a communication box, in particular to a PCB plug-in card-type puller that supports hot plugging. Background technique [0002] When pluggable PCB cards such as ATCA are used in the current communication equipment chassis structure, there are many plug-in PINs between the board card and the backplane, and it is difficult to plug in and out, so a puller is required. Generally, one board is paired with a pair. The current mainstream aids in the market such as figure 1 As shown, it includes the wrench part (2), the handle part (1) and the thrust control device (10). The wrench part (2) and the handle part (1) are split structures, and the wrench part (2) and the single board ) to rotate the connection so that the wrench part (2) can rotate relative to the veneer panel (4), and the wrench part (2) is connected to the handle part (1) so that the handle part (1) can rotate relative to the wrench part (2) ) rota...
