Detailed Description

The technical solutions in the embodiments of the present invention will be described clearly and completely with reference to the accompanying drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only some embodiments of the present invention, not all embodiments.

It should be noted that all the directional indicators (such as upper, lower, left, right, front, rear, horizontal, vertical … …) in the embodiments of the present invention are only used to explain the relative position relationship between the components, the motion situation, etc. in a specific posture (as shown in the drawings), and if the specific posture is changed, the directional indicator is changed accordingly.

In the description of the embodiments, the terms "disposed," "connected," and the like are to be construed broadly unless otherwise explicitly specified or limited. For example, the connection can be fixed, detachable or integrated; can be mechanically or electrically connected; either directly or through an intervening medium, or through internal communication between two elements. The specific meaning of the above terms in the present invention can be understood in specific cases to those skilled in the art.

As shown in fig. 1 to 3, the utility model discloses a but flexible arm of quick replacement slider, including one-level arm 10, second grade arm 20 and sliding block set 30, one-level arm 10 is the one end opening setting, and second grade arm 20 card is established in one-level arm 10, and second grade arm 20 can remove along the length direction of one-level arm 10 in the inner wall of one-level arm 10, and the length direction of here is the flexible direction of flexible arm, and the field personnel can clearly judge according to the application file expression. The sliding block assembly 30 comprises a first baffle 31, a fixing plate 32, a second baffle 33 and a sliding block 34, wherein the fixing plate 32 is fixed on the outer wall of the primary arm 10, the side wall of the fixing plate 32 close to the opening end of the primary arm 10 and the side wall of the opening end of the primary arm are on the same plane, the first baffle 31 is detachably connected to the side walls, in the embodiment, a threaded hole is formed in one side, facing the first baffle 31, of the fixing plate 32, and the first baffle 31 and the fixing plate 32 are connected through a bolt.
