[0019] The technical scheme in the embodiments of the utility model will be clearly and completely described below with reference to the drawings in the embodiments of the utility model, obviously, the described embodiments are only part of the embodiments of the utility model, not all the embodiments; based on the embodiments in the utility model, all other embodiments obtained by the ordinary skill in the art without creative labor belong to the protection scope of the utility model. EMBODIMENT

[0020] As Figures 1-2As shown, this embodiment discloses a movable connecting arm, which includes a main unit 1, a push cylinder 2 and a mast 3. The push cylinder 2 is located at the front end of the main unit 1, and the mast 3 is located at the upper end of the push cylinder 2. A movable upper connecting arm 4 is also provided at the front end of the main unit 1. A wear-resistant slider 6 is slidably provided at the lower end of the movable upper connecting arm 4, and a movable lower connecting arm 5 is slidably provided at the lower end of the wear-resistant slider 6.

[0021] The movable connecting arm can be retracted to a minimum center distance of 3245mm and extended to a maximum center distance of 4345mm, with a center distance extension range of 0-1100mm. For some areas with unstable foundations, construction can be carried out without getting close to the site; simply moving the connecting arm is sufficient.

[0022] Meanwhile, the movable connecting arm consists of a movable upper connecting arm 4, a movable lower connecting arm 5, and a wear-resistant slider 6 located between the movable upper connecting arm 4 and the movable lower connecting arm 5. The lower end of the movable connecting arm is connected to the main unit 1, which provides the power system for the entire equipment. All actions are accomplished through hydraulic oil pipes and cables released from the main unit 1. The upper end of the movable connecting arm is connected to the mast 3, and the mast moves across areas by pushing the sliding action of the hydraulic cylinder 2. The guide and direction of the sliding of the connecting arm are limited by the wear-resistant slider 6. The mast 3 suspends the rotary drilling power head and drill rod to meet the requirements of cross-area rotary drilling operations. Example

[0023] like Figures 1-4 As shown, this embodiment discloses a movable connecting arm, which includes a main unit 1, a push cylinder 2 and a mast 3. The push cylinder 2 is located at the front end of the main unit 1, and the mast 3 is located at the upper end of the push cylinder 2. A movable upper connecting arm 4 is also provided at the front end of the main unit 1. A wear-resistant slider 6 is slidably provided at the lower end of the movable upper connecting arm 4, and a movable lower connecting arm 5 is slidably provided at the lower end of the wear-resistant slider 6.
