[0031] According to the above design, the second tube body 2 is selected as a corrugated folded tube, based on the telescopic characteristics of the corrugated folded tube, the overall length of the beeler tube can be adjusted, and the convenience of storage and transportation is improved.

[0032] However, it is also due to the telescopic characteristics of the second tube body 2 that a supporting structure must be designed for it to maintain the stability of the beeler tube.

[0033] Specifically, the design scheme of the supporting structure is as follows:

[0034] A side prism 4 is provided on the outer wall of the first tube body 1, and a slide 401 is provided in the side prism 4;

[0035] A supporting ring 14 is provided on the outer wall of the third tube body 3, and a slide column 8 is provided on the supporting ring 14;

[0036] The slide column 8 is matched with the slide 401 provided in the side prism 4 and is inserted into the slide 401 provided in the side prism 4;

[0037] The side wall of the slide column 8 is provided with a limiting groove 801 distributed along the axial direction of the slide column 8, and the upper end and the lower end of the bottom surface of the limiting groove 801 are provided with a positioning hole 802;

[0038] The side prism 4 is provided with a limiting pin 11 penetrating into the limiting groove 801 and being threadedly connected with the limiting groove 801, and when the limiting pin 11 is screwed into the corresponding position, the front end of the limiting pin 11 can extend into the corresponding positioning hole 802.

[0039] In the embodiment, the side prism 4 is integrally formed with the first pipe body 1, and the support ring 14 is integrally formed with the third pipe body 3.

[0040] According to the above design, the side prism 4 and the support ring 14 are additionally arranged on the outer wall of the first pipe body 1 and the third pipe body 3, respectively, and based on the sliding cooperation between the slide 401 arranged in the side prism 4 and the slide column 8 arranged on the support ring 14 (the sliding cooperation between the slide column 8 and the slide 401 prevents the second pipe body 2 from being bent and deformed), and the limiting cooperation (the limiting cooperation between the limiting pin 11 and the limiting groove 801 limits the extension range of the second pipe body 2; the limiting cooperation between the limiting pin 11 and the positioning hole 802 enables the second pipe body 2 to be kept at the maximum extension amount or the minimum extension amount, and prevents the second pipe body 2 from being deformed in extension), a support structure is formed, which supports the second pipe body 2 without affecting the overall length of the bailer, and prevents the second pipe body 2 from being deformed in extension or being bent and deformed to affect use.

[0041] In another embodiment, the upper end of the first pipe body 1 is provided with a lifting ring 5, the lifting ring 5 is provided with a lifting rope 6 connected therewith, and a rope disc 7 is further included, and the lifting rope 6 is accommodated in the rope disc 7.
