The quick-change device comprises two components: a fixed bayonet assembly 1 and a sliding bayonet assembly 2. The fixed bayonet assembly 1 is fixed to a carrier or other fixed member and the sliding bayonet assembly 2 is fixed to a load. When the assembly load is applied, the sliding bayonet assembly 2 slides along the groove 11 in the fixed bayonet assembly 1 towards the spring pin mechanism 12, and when the spring pin mechanism 12 acts, the linkage pin 124 of the spring pin mechanism 12 is clamped in the notch 23 of the sliding bayonet assembly 2 and is installed in place.

The fixed bayonet component 1 consists of a fixed connecting plate 14, an outer clamping plate 15, a spring pin mechanism 12, an electric connecting plate 13, a spring piece 16, a screw 17 and the like.
The purpose of the securing connection plate 14 is to connect the securing bayonet assembly 1 to a carrier or other carrier. And is also a carrier for fixing the outer clamping plate 15, the spring pin mechanism 12, the electric connecting plate 13 and the elastic sheet 16. The function of the spring pin mechanism 12 is to perform the pinning and unpeeing functions after the bayonet assembly 2 is slid into place. The electrical connection plate 13 is provided with a telescopic spring needle 131 for realizing electrical connection. The elastic sheet 16 acts to press the sliding bayonet component 2 on the fixed bayonet component 1 along the up-down direction, and has certain elasticity at the same time, so as to isolate the external high-frequency vibration of the carrier (the shape is the frequency vibration spectrum according to the weight of the load).

The inner clamping plate 21 is used for positioning and connecting the fixed bayonet assembly 1 and connecting load, and the fixed electric shock plate 24 and the insulating plate 22 are installed at the same time. The inner clamping plate 21 realizes the up-down, left-right positioning with the fixed bayonet assembly 1.
