In addition, the replacement operation of the sampling components of the traditional sampler is complex, the maintenance cost is high, and it is difficult to adapt to diversified powder samples and rapid detection rhythm.

[0033] The outer part of the support sliding block 203, that is, the end away from the telescopic cylinder 201, is fixedly connected with the rotating sampling assembly 204 for sampling. The rotating sampling assembly 204 comprises a connecting fixed block two 20401, which is a connecting hinge of the rotating sampling assembly 204, and transmits the movement of the connecting telescopic rod 202 to the connecting fixed column one 20402, thereby driving the whole rotating sampling assembly 204 to move. The outer part of the connecting fixed block two 20401 is fixedly connected with two connecting fixed columns one 20402, which connect the connecting fixed block two 20401 and the connecting fixed plate 20403, play the role of force transmission and fixed structure, and ensure that each part of the rotating sampling assembly 204 can work cooperatively.

[0034] The outer part of the connecting fixed column one 20402 is fixedly connected with the connecting fixed plate 20403, which is fixedly connected with the rotating block 20404, provides support and guidance for the rotation of the rotating block 20404, enables the rotating block 20404 to rotate according to a predetermined trajectory, and the outer part of the connecting fixed plate 20403, that is, the end away from the connecting fixed block two 20401, is fixedly connected with the rotating block 20404, which converts the linear motion of the connecting fixed plate 20403 into rotary motion, drives the rotating clamping block 20405 to realize the sampling action through rotation, and the inner part of the rotating block 20404 is rotatably connected with the rotating support column 206, which provides support and positioning for the rotation of the rotating block 20404, ensures the stability and accuracy of the rotation of the rotating block 20404, the outer part of the rotating support column 206 is rotatably connected with the connecting fixed block three 205, which fixes the rotating support column 206, provides a stable mounting position for the rotating support column 206, and ensures that the rotating support column 206 will not displace or shake during the working process, the outer part of the rotating block 20404 is fixedly connected with the rotating clamping block 20405, which directly participates in the sampling action, and realizes the purpose of quantitative sampling by folding inward to grab the micro powder.

The connecting support column 303 is internally provided with an annular groove. The connecting fixed block four 304 is externally fixedly connected with the rotating connecting column 301, which connects the rotating connecting column 301 and the telescopic spring 305, and converts the rotating movement of the rotating connecting column 301 into the linear movement of the telescopic spring 305. The connecting fixed block four 304 is externally slidably connected with the telescopic spring 305, which plays a role of fixing and buffering during the mounting and dismounting of the sampling ball 306. The telescopic spring 305 is slidably connected with the sampling ball 306, which directly contacts the trace powder and obtains a quantitative powder sample through the clamping action of the rotating clamping block 20405. The connecting fixed block four 304 is internally rotatably connected with the sampling ball 306.

[0036] Working principle: when the telescopic cylinder 201 starts to operate, the connecting telescopic rod 202 is driven to slide, thereby driving the connecting fixed block two 20401 to slide, thereby driving the connecting fixed plate 20403 to slide, thereby driving the connecting rotating block 20404 to rotate, and the rotating support column 206 provides support effect for the rotation of the connecting rotating block 20404, thereby driving the rotating clamping block 20405 to fold inward, thereby achieving the sampling effect.

[0037] When it is necessary to dismount the sampling ball 306 and replace it, the rotating connecting column 301 is rotated, thereby driving the connecting fixed column two 302 to rotate, and the connecting support column 303 standardizes the rotating position of the connecting fixed column two 302. At the same time, the rotating connecting column 301 drives the connecting fixed block four 304 to rotate forward, thereby driving the telescopic spring 305 to slide forward, thereby compressing the telescopic spring 305 to achieve the fixing effect.
