In order to further increase the locking and fixing effect between the installed connecting device 1 and the special-shaped rod element 7 during installation, the cross-sectional shape of the installation groove 8 is set to be a trapezoid with a narrow outside and a wide inside, the installation wall 8a in the installation groove 8 extends in the axial direction of the special-shaped rod element 7 in a plane shape and is directly connected between the supporting wall 8a and the connecting wall 8c at a certain angle, preferably, the included angle between the installation wall 8b and the main body part of the connecting wall 8c is an acute angle, then a first inclined surface part 8ba is formed on the inner side of the installation wall 8b, and the fixture block 2 is set to be in a shape corresponding to the installation groove 8, and then a second inclined surface part 2d for abutting contact corresponding to the first inclined surface part 8ba is formed on the clamping part 2 b. After the bolt 3a, the fixture block 2, the abutting base 4a and the special-shaped rod 7 abut against each other, the locking member 3 is screwed in a continuous rotating manner, at this time, the fixture block 2 has a tendency to move outwards in the radial direction of the special-shaped rod 7, the squeezing acting force between the first inclined surface portion 8ba and the second inclined surface portion 2d is increased, and meanwhile, a larger friction force is generated between the contact surfaces to lock the connecting device 1 convenient to mount at the position.

On the basis of the above structure, an anti-slip structure 2da for increasing friction force, specifically an inner groove or an outer convex rib in the horizontal or vertical direction distributed on the contact surface, may be further provided on the second inclined surface portion 2 d; further preferably, a point-like protrusion or a point-like depression may be further disposed on the contact surface to continuously increase the friction between the latch 2 and the profile rod 7, so as to improve the structural firmness and stability.

Example 4: the multifunctional rod 6 in the above embodiment is further preferably selected, the device mounting base 4 and the abutting base 4a are integrally connected and molded, and a reinforcing structure 4b extending in the vertical direction is formed at the joint of the device mounting base 4, the abutting base 4a or both by bending, stamping, welding reinforcing ribs and the like, so that the bending resistance of the connecting device 1 convenient to mount in the vertical direction is further improved, and the bearing capacity and the durability of the device are improved; the equipment installation seat 4 has various shapes, and connection structures matched with various equipment needing to be installed, such as installation holes 4c of through holes, threaded holes and the like or clamping grooves and the like, can be arranged on the equipment installation seat 4, and meanwhile, the equipment installation seat 4 can be expanded and extended towards all directions or can be bent around the special-shaped rod piece 7 towards all directions to form various shape structures.

When the multifunctional rod 6 is actually manufactured, installed and used, the connecting device 1 convenient to install is provided with the plurality of clamping blocks 2 along the axial direction of the special-shaped rod piece 7, the structure can avoid the phenomenon that when a single clamping block 2 is connected, the equipment mounting frame 4 and the additional device equipment shake and rotate around the rotation center of the clamping block 2 to cause the loosening of the joint, and can play a role in protection when a certain joint loosens and fails, so that the stability and the safety of the multifunctional rod 6 are improved. For the manufacturing process method of the special-shaped rod piece 7, the cylindrical steel is selected to be manufactured through cold drawing treatment and integrated forming, a plurality of mounting grooves 8 are formed in the circumferential direction of the special-shaped rod piece 7, the mounting grooves 8 are arranged on the side face of the special-shaped rod piece 7 in a pairwise opposite mode, the length, the position and the opening size of each mounting groove 8 can be adjusted to various specifications and sizes according to different types of devices and equipment to be mounted, and the mounting grooves are connected with the matched fixture blocks 2, so that the application range of the multifunctional rod 6 is greatly expanded, and the wide popularization of the multifunctional rod 6 is facilitated. Meanwhile, the installation space of the equipment device which needs to be additionally installed in the future can be reserved by the preset installation groove 8 in the special-shaped rod piece 7, the multifunctional rod 6 does not need to be punched, welded and the like, the workload of subsequent installation equipment is greatly reduced, the installation and operation process is simplified, the working time is effectively saved, and the working efficiency is improved. A plurality of mounting grooves 8 in the special-shaped rod piece 7 enable the cross section of the special-shaped rod piece 7 to contain a plurality of triangular connection structures, so that the special-shaped rod piece 7 forms an overlapped composite reinforcing effect in a plurality of directions, the capability of resisting bending and torsion when the special-shaped rod piece 7 is vertically fixed on the ground is greatly enhanced, severe weather conditions such as typhoon and rainstorm can be effectively responded, or the multifunctional rod piece 6 is not damaged when being collided lightly, and the durability and the safety of the multifunctional rod piece 6 are effectively improved.
