Preferably, the slope of the second sloping side is greater than the slope of the first sloping side to allow for more reasonable forces during contact.
Further, it is preferable that both ends of the spring portion 32 are connected to the first slider 34 and the second slider 35, respectively, and the spring portion 32 is always pulled to generate elastic tensile force to act on the first slider 34 and the second slider 35, respectively. When the adjusting cylinder 311 is not actuated, the elastic tension of the spring part 32 causes the first slider 34 and the second slider 35 to abut together, and the space between the first traction wheel 21 on the first slider 34 and the second traction wheel 22 on the second slider 35 is the smallest, corresponding to the smallest diameter of the sleeve 100 that can be clamped at this time. When the adjusting cylinder 311 extends, the spring portion 32 is further pulled, the generated elastic pulling force resists the first sliding seat 34 and the second sliding seat 35 to move towards each other, at this time, the interval between the first traction wheel 21 on the first sliding seat 34 and the second traction wheel 22 on the second sliding seat 35 can be adjusted according to the size of the diameter of the sleeve 100, and the elastic force generated by the spring portion 32 can enable the first traction wheel 21 and the second traction wheel 22 to clamp the sleeve 100 no matter the diameter of the sleeve 100 is large.
Compared with a device arranged for clamping the sleeve 100 in the prior art, the adjusting assembly 3 provided by the invention has the advantages that the structure is simpler, the design is more ingenious, the sleeve 100 can be automatically clamped only by controlling the extension and retraction of the adjusting cylinder 311, the clamping force can be realized by adjusting the spring stiffness of the spring part 32, and the reliability is higher.
