The utility model is further provided with: threads are arranged at two ends of the central hollow cylinder, and an exhaust hole is formed in the central part of the central hollow cylinder.
Through adopting above-mentioned technical scheme, the hollow section of thick bamboo in the center can be fixed in the barrel, and the exhaust hole can balance the atmospheric pressure in the hollow section of thick bamboo in the center when the telescopic shaft stretches out and draws back.
The utility model is further provided with: a bulge is arranged on one side of the telescopic shaft.
By adopting the technical scheme, the roller can be fixed in the machine when the roller is used.
The utility model is further provided with: the anti-slip nut is characterized in that a through hole is formed in the center of the anti-slip nut, the size of the through hole on one side, close to the reset spring, of the anti-slip nut is matched with the size of the hollow cylinder in the center, and the size of the through hole on one side, far away from the reset spring, of the anti-slip nut is matched with the size of the protrusion.
By adopting the technical scheme, the telescopic shaft is prevented from sliding out of the hollow central cylinder.
The utility model is further provided with: the hollow center cylinder is in threaded connection with the anti-slip nut.
By adopting the technical scheme, the hollow central cylinder is fixed in the cylinder body.
In summary, the utility model has the following beneficial effects: the telescopic shaft is fixed in the hollow cylinder of center, and the hollow cylinder of center is fixed in the cylinder body, and the reset spring in the hollow cylinder of center provides elasticity for the telescopic shaft, and the telescopic shaft of roller both sides can both be compressed, can install and tear open the change fast when using.

Detailed Description
In order that those skilled in the art will better understand the present invention, a more particular description of the invention will be rendered by reference to specific embodiments thereof which are illustrated in the appended drawings, wherein it is to be understood that the illustrated embodiments are merely exemplary of some, but not all, of the invention. All other embodiments, which can be made by those skilled in the art based on the embodiments of the present invention without making any inventive effort, shall fall within the scope of the present invention.
It should be noted that, without conflict, the embodiments of the present invention and features of the embodiments may be combined with each other. The present invention will be described in detail with reference to examples.
Examples:
The roller capable of compressing at two ends comprises a roller body 4, wherein openings 11 are formed in two ends of the roller body 4, anti-slip nuts 2 are welded in the openings 11 in two ends of the roller body 4, bearings 3 are fixed at two ends of the inner portion of the roller body 4, a central hollow cylinder 6 is arranged in the roller body 4, two ends of the central hollow cylinder 6 penetrate through the bearings 3 to the inside of the anti-slip nuts 2, a reset spring 5 is sleeved in the central hollow cylinder 6, and telescopic shafts 1 are sleeved at two ends of the inner portion of the central hollow cylinder 6.
Further, the two ends of the central hollow cylinder 6 are provided with threads 10, and the central part of the central hollow cylinder 6 is provided with an exhaust hole 7. A bulge 8 is arranged on one side of the telescopic shaft 1. The center of the anti-slip nut 2 is provided with a through hole 9, the size of the through hole 9 at one side of the anti-slip nut 2 close to the reset spring 5 is matched with the size of the central hollow cylinder 6, and the size of the through hole 9 at one side of the anti-slip nut 2 far away from the reset spring 5 is matched with the size of the bulge 8.
