Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0024] Example 1

[0026] After the adjusting structure 13 is driven, the second cylinder 12 is pulled to slide to a suitable position outside the first cylinder 11 , and the adjusting structure 13 is driven again to fix the second cylinder 12 on the first cylinder 11 .

[0027] Specifically, the adjustment structure 13 includes two guide plates 131 symmetrically arranged on the side walls of the inner cavity of the first cylinder 11, a clamping plate 132 slidably arranged on the guide plate 131 and fixedly connected to one end of the second cylinder 12, a fixing rod 133 fixedly arranged in the cavity of the first cylinder 11, two clamping plates 134 rotatably mounted on the outside of the fixing rod 133, and a driving structure 135 arranged in the cavity of the first cylinder 11 for driving the clamping plate 134 to rotate.

[0028] When adjusting the length of the circular cylinder 1, the driving structure 135 is driven to drive the clamping plate 134 to rotate around the fixed rod 133, so that the clamping plate 134 is separated from the clamping plate 132, and the second cylinder 12 is pulled so that the clamping plate 132 fixed on the second cylinder 12 slides to a suitable position on the guide plate 131 fixed on the first cylinder 11, and then the driving structure 135 is driven again to make the clamping plate 134 rotate around the fixed rod 133 and clamped with the clamping plate 132, and the second cylinder 12 is fixed on the outside of the first cylinder 11.

[0029] In order to facilitate the adjustment of the length of the circular cylinder 1 and fix the clamping plate 134 , a linearly distributed clamping groove 1321 is provided on the clamping plate 132 , and one end of the clamping plate 134 is clamped in the clamping groove 1321 .

[0030] More specifically, the driving structure 135 includes a sliding plate 1351 slidably arranged on both sides of the first cylinder 11 and abutting against one end of the clamping plate 134 away from and clamped by the clamping groove 1321, a guide plate 1352 fixedly arranged in the cavity of the first cylinder 11 and slidably connected to the sliding plate 1351, a fixed plate 1353 fixedly arranged in the cavity of the first cylinder 11 and located at the end of the guide plate 1352 away from the clamping plate 134, a compression spring 1354 with two ends fixedly connected to the fixed plate 1353 and the sliding plate 1351 respectively, and a tension spring 1355 with two ends fixedly connected to one end of the two clamping plates 134 close to the sliding plate 1351, and the end of the sliding plate 1351 away from the clamping plate 134 passes through the first cylinder 11.

[0031] When the sliding plate 1351 is pulled, the clamping plate 134 rotates around the fixed rod 133 under the pulling force of the tension spring 1355, so that the end of the clamping plate 134 away from the tension spring 1355 is disengaged from the slot 1321 provided on the clamping plate 132, and then the second cylinder 12 is pulled to slide to a suitable position outside the first cylinder 11, and then the sliding plate 1351 is released. The sliding plate 1351 slides in the first cylinder 11 under the action of the compression spring 1354, so that the clamping plate 134 rotates around the fixed rod 133, and the end away from the tension spring 1355 is engaged with the slot 1321 provided on the clamping plate 132, so that the second cylinder 12 is fixed on the first cylinder 11.

[0032] It should be noted that in order to prevent the circular cylinder 1 from deforming and affecting its use, the reinforcement structure 2 includes a plurality of annular plates 21 linearly distributed in the first cylinder 11 and the second cylinder 12 and connecting plates 22 annularly distributed between the annular plates 21 and fixedly connected to the annular plates 21 at both ends.
