In order to further increase the stable supporting effect of the support rod 2, the device further arranges the arc-shaped plate 23, increases the contact area of the support rod 2 and the pipeline, and thus enhances the supporting effect, so that the anti-collapse effect is better.

[0044] As shown in Figure 3 Further, a plurality of protrusions 24 are arranged on the side of the arc-shaped plate 23 away from the support rod 2. Because the arc of the arc-shaped plate 23 does not necessarily adapt to the pipelines of various diameters, the arc-shaped plate 23 does not necessarily completely contact with the inner wall of the pipeline when supporting. In order to further increase the contact area of the arc-shaped plate 23 and the pipeline, the device arranges a plurality of protrusions 24 on the side of the arc-shaped plate 23 contacting with the pipeline, which can increase the contact area with the pipeline on the one hand, and can also play a role in anti-skid on the other hand, so as to enhance the supporting effect, so that the anti-collapse effect is better.

[0045] Wherein, other structures of the embodiment are consistent with embodiment 1, only optimization is made to embodiment 1.

It is equivalent to using a worm gear instead of the first bevel gear 32 and a worm instead of the second bevel gear 33, and the working principle is that the driving member 34 drives the driving shaft 31 to rotate, so that the worm gear on it rotates synchronously, because the plurality of worm gears are engaged with the worm gear, therefore, the plurality of worm gears are driven to rotate synchronously, so as to make the plurality of support rods 2 rotate, realize the simultaneous adjustment of the plurality of support rods 2 to the cylinder 1 outward or inward, and the operation is more convenient.

[0048] Wherein, this embodiment only replaces the transmission assembly in embodiment 1, and the other structures remain unchanged.

[0049] The advantages of the device are that the device is circumferentially screwed with a plurality of support rods on the cylinder, the plurality of support rods can be used for preventing the pipe from falling, and the support rods can be adjusted to outward or inward contraction when the support rods are rotated, that is, the length of the support rods can be adjusted according to the size of the pipe inner diameter, the adaptability is wider, and the device is further provided with a driving structure, the rotation movement of the driving shaft can be transmitted to the rotation movement of the plurality of support rods through the transmission assembly, so that the plurality of support rods can be simultaneously adjusted to the cylinder outward or inward, and the use is more convenient.
