In the prior arts, when mounting the handle (for example when mounting the door lock handle), the clamping screws 315 (fastener 310) are often provided to firmly connect the two ends of the handle. The mounting is not convenient and now requires a fairly long time. During long-term handle pulling, the screws 315 connecting the two ends of the handle are easily rotatable with the door handle rotation. Over time, the clamping screw 315 is likely to become loose.

[0027] The technical solution in the present invention provides a quick mounting handle, has solved the problems existing in the prior art such as unstable handle structure, inconvenient mounting, high mounting cost, etc. Due to the combination between the reverse mounting fixing member 310 and the locking member 320, it is able to achieve better favorable effects with stable structure, favorable mounting and reduced mounting cost.

[0028] To solve the above-mentioned technical problems, the present invention is based on the general philosophies of the embodiments as follows:

And a series of technical means are thus applicable. In this way, after tightening the locking elements 320 to the predefined angle in the predefined direction, the fasteners 310 are mounted in the reverse direction by exerting traction on the head 313 to tighten the fasteners 310 in order to; complete the handle assembly in the short term and reduce the assembly hours required. When rotating the handle 1, the fasteners 310 are not driven in order to reduce the possibility of detachment of the fasteners 310.

[0030] When assembling, no screwdriver for screw 315 is provided to tighten the fixing member 310 (screw 315). The locking member 320 (lock plate 321) is tightened to a certain angle to thereby tighten the screw 315, the assembly time of which is only a few seconds to reduce operation procedures of screw 315 and improve convenient assembly. When rotating the handle 1 (door handle) during door opening, the clamping member 320 will not be driven by the handle 1. No external force is exerted on the screw 315 to prevent detachment and improve structural stability.
