あつた。 In a three-stage telescopic boom, it has been known for a long time that the drill support frame can be selectively locked to the base boom and the tip boom, as described in, for example, Japanese Patent Laid-Open No. 52-9906. However, in conventional auger holding devices, the cross-sectional outline of the tip of the tip boom is either the same as the cross-sectional outline of the intermediate boom, or
Or, it was formed larger than that, and the drill support frame was fitted to the tip of the tip boom, so the auger could not be locked to the middle part of the tip boom during excavation work with the auger. Ta.

られている。 Embodiments of the present invention will be described below with reference to the drawings. An intermediate boom 2 and a tip boom 3 are connected to the base boom 1 in a telescopic manner, and the intermediate boom 2
The tip boom 3 is extended and retracted simultaneously or sequentially by a built-in telescoping device (not shown). A sleeve 4 having a collar 4' at the tip is slidably fitted to the outer periphery of the tip boom 3.
The outer circumferential surface of the intermediate boom 2 is formed to be equal to the outer circumferential surface of the intermediate boom 2, and when the sleeve 4 is positioned at the tip of the intermediate boom 2, the outer circumferential surfaces of the sleeve 4 and the intermediate boom 2 form a smooth continuous surface. An auger support 5 is slidably fitted on the outer periphery of the intermediate boom 2, and an auger 7 is attached to the auger support 5 via a link 6.
