[0019] In order to make the purpose, content and advantages of the present invention more clear, the specific implementation methods of the present invention are further described in detail below in conjunction with the drawings and examples.

[0020] This embodiment provides a simple movable support rod with rotation orientation and wedge-shaped fixing functions, and its structure is as follows: Figure 1 As shown, it includes a support rod 1, a support seat 2, a wedge block 3, a fastening screw 4, a pin 5, an open retaining ring 6, a gasket 7 and a fixing bolt 8.

[0021] The support seat 2 is a groove-shaped structure as a whole, and the bottom surface is fixed to the wall surface by fixing bolts 8. The two walls of the groove of the support seat 2 can be in the shape of a straight line, an arc surface with an arc transition, a rectangular surface or a special-shaped surface, and groove through holes are respectively provided on the two walls of the groove. A flat plate with threaded holes is connected to the upper side of the two walls of the groove, and the fastening screws 4 can be screwed into the threaded holes of the flat plate. The flat plate and the support seat 2 become an integrated structure, and the two walls of the groove and the flat plate form a rectangular opening.

[0022] The support rod 1 can be a solid or hollow strip, column or special-shaped structure. A shaft hole is provided on both sides of the inner end of the support rod 1, and the distance between the shaft hole and the inner end surface of the support rod 1 is equal to the distance from the lower side of the support rod 1, so that the wedge block 3 can lock the support rod 1 in both the supporting and contracting states. A groove is provided on the lower side of the support rod 1 to accommodate the bolt cap of the fixing bolt 8. The support rod 1 is installed on the groove through hole of the support seat 2 through the pin 5, and gaskets 7 are added on both sides of the support rod 1. The pin 5 is tightened by the open retaining ring 6, so that the support rod 1 can rotate around the pin 5 in the groove of the support seat 2.

[0023] An opening is provided in the middle of the lower end of the wedge block 3 for accommodating the fixing bolt 8. A groove is provided at the upper end of the opening of the action surface of the wedge block 3, and a protruding brim portion is provided at the upper end of the action surface of the wedge block 3 to facilitate the up-and-down movement of the wedge block 3. The wedge block 3 is inserted from the rectangular opening formed by the two walls of the groove of the support seat 2 and the flat plate, and the plane of the wedge block 3 leans against the bottom surface of the groove of the support seat 2. When the action surface of the wedge block 3 is fully in contact with the support rod 1 without a gap, the fastening screw 4 is tightened so that the end surface of the fastening screw 4 presses against the groove of the wedge block 3 to prevent the wedge block 3 from loosening.

[0024] like Figure 2 As shown, whenever the support rod 1 needs to be switched between the supporting state and the retracted state, first loosen the fastening screw 4 counterclockwise, pull up the wedge block 3, and swing the support rod 1 to the required position (supporting state->approximately horizontal position; retracted state->approximately vertical position), then insert the wedge block 3 downward to lock the support rod 1, and finally use the fastening screw 4 to tighten the wedge block 3 clockwise to reach the locked state to complete the conversion.

[0025] The structure of the support rod 1 in the supporting state is as follows: Figure 3 As shown, the support rod 1 is swung to a roughly horizontal position, and then the wedge block 3 is inserted from the rectangular opening of the support seat 2. When the action surface of the wedge block 3 is fully in contact with the end surface of the support rod 1 without a gap, the support rod 1 has been completely fixed by the resistance of the wedge block 3. Finally, the wedge block 3 is tightened with the fastening screw 4 to reach a locked state. In this state, the support rod 1 can play a role in stable support.

[0026] The structure of the support rod 1 in the contracted state is as follows: Figure 4As shown, the support rod 1 is swung to a roughly vertical position, and then the wedge block 3 is inserted from the rectangular opening of the support seat 2. When the action surface of the wedge block 3 is fully in contact with the lower side of the support rod 1 without a gap, the support rod 1 has been completely fixed by the resistance of the wedge block 3, and finally the wedge block 3 is tightened with the fastening screw 4 to reach a locked state. The support rod 1 is also fixed in the retracted state and will not produce abnormal noise with the vibration of the vehicle body.

[0027] The above is only a preferred embodiment of the present invention. It should be pointed out that for ordinary technicians in this technical field, several improvements and modifications can be made without departing from the technical principles of the present invention. These improvements and modifications should also be regarded as the scope of protection of the present invention.
