Abstract: A mounting device for easy mounting of a wireless device includes a clamping structure configured to clamp a support frame. The clamping structure includes a base including an upper surface and a lower surface, a first clamping part rotatably connected to the base, a second clamping part rotatably connected to the base, and a connection portion connected to the lower surface of the base. The wireless device is thus supported. The support frame is clamped between the upper surface and the first clamping part, and the support frame is clamped between the upper surface and the second clamping part.

Abstract: An angle adjusting mechanism for a mouthpiece bearing portion of a telephone includes a hinge, a guiding member, a connecting member, a pushing member, a first wheel, and a second wheel. The hinge and the guiding member are fixed on opposite ends of the connecting member. The first wheel is fixed on the pushing member, and the second wheel is fixed on the mouthpiece bearing portion. The first wheel and the second wheel engage together and an end of the pushing member is connected to the guiding member. The hinge can rotate to slide the pushing member to rotate the first wheel. The second wheel turns to achieve a constant angle for the handset bed even if main body of telephone is propped up to an angle from a supporting surface.

Abstract: A telephone uses a locking mechanism for a handset where the handset includes a receiver part and a microphone part. The receiver part defines a receiving groove facing the microphone part. The telephone set includes a holding part to hold the handset. The holding part includes a first portion. The first portion defines a recess to receive the receiver part, and an accommodating space to receive the locking mechanism. The locking mechanism is rotatably received in the accommodating space and is switchable between a first state and a second state. The locking mechanism has a locking block. In the second state, the locking block is locked in the receiving groove of the receiver part to prevent release of the handset from the telephone set.
