Claims

[Claims for Utility Model Registration] (1) Consists of a support part connected to the rear or front part of a working vehicle, and a working part supported by the support part, and the working part is connected to the support part. On the other hand, in a work machine configured to be slidable in the left-right direction of the work vehicle, the support portion may be a pair of support plates having one end pivoted to a hitch provided at the rear or front of the work vehicle. , a lower mast consisting of a pillar fixed to the other end of the support plate and a guide frame bridged between the pillars, an inner cylinder slidably passing through the pillars, and a guide frame bridged between the upper ends of the inner cylinder. an upper mast, a pair of engaging parts that slidably engage guide frames of the upper and lower masts, and a slide frame that connects with the working part; one end of which is connected via a connecting rod to a three-point link hitch installed on a work vehicle, and the other end of which is engaged with the support plate; A slide fixing device for a working machine, characterized in that the lower end of an inner cylinder of an upper mast is brought into pressure contact with the ground by rotating in the direction, thereby increasing the distance between the guide frames of the upper and lower masts. (2) Consists of a support part connected to the rear or front part of the work vehicle, and a working part supported by the support part, and the work part is oriented in the left-right direction of the work vehicle with respect to the support part. In a work machine that is configured to be slidable, the support portion is comprised of a pair of support plates having one end fixed to the rear or front part of the work vehicle, and a column and a support plate fixed to the other end of the support plate. a lower mast consisting of a guide frame bridged between the lower ends of this column; an upper mast consisting of a guide frame bridged between an inner cylinder slidably inserted into the column and the upper end of the inner tube protruding from the column; , an outrigger cylinder that is integrated into the inner cylinder of the upper mast and has a piston rod tip protruding downward from the lower end of the column, and a pair of engaging parts that slidably engage with the guide frames of the upper and lower masts. and a slide frame connected to the working part, and the distance between the guide frames of the upper and lower masts is widened by the pushing action of the tip of the piston rod against the ground by the extension action of the outrigger cylinder. A slide fixing device for a working machine, characterized in that:
