Preferably, the fixing portion 100 further includes a roller 120, when the support rod is inserted radially from the opening 110, a distal end 121 of the roller 120 contacts the support rod and rotates in accordance with the insertion direction to assist the support rod to be inserted into the support rod until reaching the central position, and thereafter, a clamping end 122 of the roller 120 keeps tightly abutting against the support rod to keep the support rod fixed at the central position. Referring to fig. 5, the farthest end 121 is a position where a distance between a tangent line of the outer contour of the roller 120 and a central point of the fixing portion 100 is the smallest, the clamping end 122 is a position where the supporting rod is smoothly clamped and tightly abutted against the outer surface of the supporting rod body 300, and the static friction generated by the roller 120 replaces the static friction generated when the supporting rod is clamped by simply relying on the hard rancour mode of elastic deformation of the soft rubber pad, so that the frictional resistance of the supporting rod when the supporting rod is clamped can be effectively reduced, and the supporting rod can be more flexibly adapted to the size of the supporting rod in a wider range.

Preferably, 5 fixing posts 101 are provided, and are disposed on the arc-shaped edge of the fixing portion 100 in six equal parts. The roller 120 is disposed at the sixth-circle position, and the roller 120 is disposed at the entrance side of the insertion path of the support rod, when the support rod is inserted, the support rod is firstly abutted by the roller 120, and can continuously move to the central position under the rolling friction of the roller 120 to reach the central position, and is abutted by the roller 120, so as to be difficult to be easily released. Further, the roller 120 may be disposed near the sextant circle of the rod 300 for easy application of force. In other embodiments, it is fully feasible to adaptively set the number of the fixing posts 101 to three, or more. It is only necessary to ensure that the farthest end 121 and the abutting end of the roller 120 do not overlap, and the supporting rod contacts the farthest end 121 first and is abutted by the abutting end after passing over the farthest end 121 in the process of being inserted.

In order to fix the roller 120, the following is prevented from being generated after the following support rod is clamped. The roller 120 is fixed on the fixing post 101 in a sleeving manner. Adaptively, the positioning ring 104 needs to be adjusted according to the change, for example, a groove may be formed on the positioning ring 104, and a certain accommodation area 1041 is reserved to accommodate the placement of the roller 120. Such that the roller 120 is disposed with a surface having the same height as the retaining ring 104 to facilitate a snug fit with other structures.

Preferably, the roller 120 includes the central part 123 with fixed column 101 clearance fit, and the cover is located the central part 123 peripherally, the outside 124 of adopting flexible material preparation, adopt clearance fit to further reduce roller 120 around fixed column 101 pivoted rolling friction, more do benefit to roller 120 and take place to rotate under the inserted drive of bracing piece, outside 124 adopts flexible material can make when the bracing piece inserts, take place elastic deformation, make the bracing piece block central point smoothly, and utilize self deformation to support tight bracing piece, prevent that the bracing piece from deviating from easily.

Preferably, intermeshing teeth 125 are provided between the central portion 123 and the outer portion 124, the teeth 125 being arranged to ensure synchronous rotation of the central portion 123 and the outer portion 124, preventing rotational misalignment.

Preferably, the outer portion 124 can be provided with a plurality of small holes 126 arranged along the axial direction, the elastic movement of the outer portion 124 is further increased by the small holes 126, so that the outer portion 124 has larger telescopic and deformable space to accommodate the size of the supporting rod in a larger range, and the arrangement along the axial direction can ensure that the roller 120 can obtain better elastic movement space at any position. Preferably, the outer portion 124 may be made of silicone or soft gel material to maintain elasticity and ductility.

In other embodiments, the first receiving groove 400 and the second receiving groove 500 may be fixed to the rod 300 in a plurality of ways, for example, the first receiving groove 400 is integrally formed in the hollow space of the rod 300, or the second receiving groove 500 is detachably fixed to the rod 300 by a buckle or a slide rail, and so on.

In other embodiments, in order to realize the sliding position limitation of the clamping structure in the first receiving groove 400, there are many implementation manners of the position limitation structure. For example, the position-limiting structure may be a position-limiting member 503 disposed on the clamping structure and/or the first receiving groove 400, and the position-limiting member 503 may be in the form of a bottom, middle or side extending/recessed clamping protrusion, a clamping groove, a clamping edge, or an abutting surface that cooperate with each other to form a slope/step surface. Or adopt spacing structures of other forms such as external spacing set screw, bolt, card protruding.

In other embodiments, in order to realize the fixed point position after the telescopic rod 901 assembly is turned around the second rotating shaft 701, a damping member may be additionally disposed on the second rotating shaft 701, or a positioning protrusion 502 may be additionally disposed on the second rotating shaft 701.

The above description is only for the specific embodiments of the present invention, but the protection scope of the present invention is not limited thereto, and any person skilled in the art can easily think of the changes or substitutions within the technical scope of the present invention, and all should be covered within the protection scope of the present invention.
