Further, the connecting portion of the handle 200 extends outward to form a limiting portion 220, the bottom plate 101 is provided with a limiting post 130 matched with the limiting portion 220, and when the handle 200 rotates to the second position, the limiting portion 220 abuts against the side wall of the limiting post 130, so that the handle 200 is prevented from rotating excessively to deviate from the second position.

Preferably, the bottom plate 101 is provided with a fixing block 120, and the first end 310 of the torsion spring 300 is inserted into the fixing block 120, so as to fix the first end 310 of the torsion spring 300. In this embodiment, the fixing block 120 is a semicircular ring, the fixing block 120 is disposed on the bottom plate 101, and the first end 310 is disposed through the fixing block 120. Further, the first end 310 and the second end 320 are both parallel to the bottom plate 101, thereby ensuring the optimal direction of the force.

The detachable handle 200 may further include a first fastening member 400, the first fastening member 400 is fixed to the base plate 101 through the connection portion of the handle 200, and the connection portion of the handle 200 is rotatably connected to the first fastening member 400. Similarly, the detachable handle 200 may further include a second fastening member 500, the second fastening member 500 is fixed to the bottom plate 101 through the torsion spring 300, and a spacer is preferably disposed between the first fastening member 400 and the connecting portion of the handle 200, so as to increase a contact area therebetween and prolong a service life of the handle 200. The first and

second fasteners

400 and 500 are preferably rivets.

Preferably, the side of the grip portion of the handle 200 facing away from the side plate 102 is provided with a grip groove 230 to facilitate gripping by a hand when pulled outwardly.

In summary, the utility model is particularly suitable for the board card assembly by arranging the pull-assisting assembly on the detachable panel main body, thereby realizing the quick and stable pull-out and removal of the board card assembly from the chassis without the help of external tools; and through the cooperation of the first end and the second end of the torsion spring with the first pressing surface and the second pressing surface of the handle, the stability of the handle at the first position and the second position is realized, namely the handle is stable at the opening position and the closing position and can not rotate freely, thereby further facilitating the dismounting operation.
