When, there is friction between only wear-resisting spill spin block 3-2 and wear-resisting fixed block 3-1, driving device 1 and clamp device 2 will not go out
It now wears, and cooperates between wear-resisting spill spin block 3-2 and wear-resisting fixed block 3-1 for rolling friction, reduce wear-resisting spill spin block 3-2
With the degree of wear between wear-resisting fixed block 3-1.Even if wearing after a certain period of time in rotation, wear-resisting rotation is also only needed to change
Block 3-2 or wear-resisting fixed block 3-1, effectively reduces the production and use cost of anticollision reaction tube grabbing device, improves anticollision
The service life of reaction tube grabbing device.
To sum up, the analyzer of the utility model both can be reduced anticollision by the way that wear-resistant device 3 and anticollision device, collision-prevention device 4 is rationally arranged
The abrasion of reaction tube grabbing device, and can prevent clamp device 2 and other components from severe crash occurs.
The above is preferred embodiments of the present invention, it is noted that for the ordinary skill of the art
For personnel, under the premise of not departing from principle described in the utility model, it can also make several improvements and retouch, these improvement
It also should be regarded as the protection scope of the utility model with retouching.
