The head 11 has a plurality of protruding strips 111 which are located on the outer peripheral surface and are spaced apart from one another about an axis 24. The head 11 can be gripped and rotated by a user's finger to lock the shaft portion 12 of the support member into the expansion member 2, and the protruding strips 111 of the head portion 11 can achieve slip resistance. The effect, while other forms of texture, as long as The outer peripheral surface of the head 11 has sufficient roughness and can also achieve slippage, and is also an equivalent structure of the preferred embodiment. The shaft portion 12 has a threaded section 121 adjacent the head portion 11 and an abutting section 122 remote from the head portion 11. The thread segment 121 has a plurality of threads 123. The abutting section 122 is at the end farthest from the head 11, and has a circular arc shape that reduces friction.

The expansion member 2 includes a base portion 21 surrounding the axis 24 and having an inner ring surface having a plurality of threads 213 for the threaded portion 121 to be locked, a hole 512 connecting the base portion 21 and extending into the mounting wall 5 and having The outer expansion portion 222 has an outer expansion body 22 and a stop portion 23 connected to an end of the base portion 21 away from the outer expansion body 22. The base portion 21 has a first end 211 connected to the outer expansion body 22 and a second end 212 opposite to the first end 211.

The flared portions 222 of the outer expansion body 22 are spaced apart from each other by the base portion 21 in a direction away from the head portion 11. The outer flared portions 222 collectively surround the axis 24, and cooperate to define a The abutting section 122 of the holder 1 projects into the tapered hole 221. The aperture of the tapered hole 221 is gradually reduced in a direction away from the base portion 21, and the tapered hole 221 continues to extend after its aperture is smaller than the diameter of the abutting portion 122.

It should be noted that the number of the external expansion portions 222 may also be two, three or more, so that the same effects as the preferred embodiment can be achieved. In addition, although the outer expansion portions 222 of the present embodiment are spaced apart from each other, the outer expansion portions 222 may be at least partially connected to each other. In addition, in the preferred embodiment, the base portion 21 is locked by the threaded portion 121, so that the outer diameter thereof is larger than the outer diameter of the outer expansion body 22, but the outer diameter of the base portion 21 and the outer expansion body 22 are The size of the outer diameter is not limited to this comparison. In the case of the preferred embodiment, the outer diameters of the two may be equal or the outer diameter of the outer expansion body 22 is larger.

At this time, the support member 1 is abutted. The top section 122 has not yet protruded into the tapered bore 221 of the expansion member 2, and the flared portions 222 of the outer expansion body 22 assume the original state and abut against the axis 24. When the threaded portion 121 of the supporting member 1 is gradually screwed into the base portion 21, the abutting portion 122 of the supporting member 1 gradually extends into the tapered hole 221, and when the abutting portion 122 is advanced to the tapered hole When the aperture 221 is smaller than the diameter of the abutting section 122, the outer expansion portions 222 are opened, and the front ends of the outer expansion portions 222 are radially away from the axis 24 and The hole surrounding surface 511 of the mounting wall 5 is abutted, so that the expansion member 2 is locked in the hole 512. On the contrary, when the user rotates the support member 1 about the axis 24 and the thread segment 121 gradually withdraws from the base portion 21, the outer expansion portions 222 will return to the original size as shown in FIG. The outer surface of the outer expansion portion 222 no longer abuts against the hole surrounding surface 511, and the expansion member 2 is facilitated to move out of the hole 512.

In summary, the novel support device can be expanded by forming a tapered hole 221 with an inconsistent aperture in the outer expansion body 22 and a design of the abutting portion 122 of the support member 1. The change is firmly clamped in the hole 512, so that the novel support device can be firmly coupled with the mounting wall 5. Moreover, the expansion member 2 can also be easily moved into and out of the hole 512 by returning to a state that is not originally opened. Therefore, the present invention can be easily installed and removed, and the installation is stable.
