Compare earlier be connected support 1 with the ceiling among the prior art, again with 1 threaded connection's of projecting apparatus 4 and support mounting means, the utility model discloses need not to stand in the eminence and rotate a plurality of screws in proper order when the installation, and first connecting pipe 11 is connected the back disect insertion second connecting pipe 12 with projecting apparatus 4 and is fixed through holder 3, can install projecting apparatus 4, such mounting means is convenient more, swift.

Referring to fig. 1, in order to open the clamping member 3, a handle portion 6 is disposed at one end of the clamping member 3 away from the fixing portion 31, and the handle portion 6 is obliquely disposed on the clamping member 3, and forms an obtuse angle with the clamping member 3. When holder 3 was closed, holder 3 and second connecting pipe 12 kept away from the angle between the 11 one ends of first connecting pipe for the acute angle, have movable region between holder 3 and the second connecting pipe 12, and the operator only need hold between the fingers portion 6, rotates handle portion 6 to with second connecting pipe 12 butt, can open holder 3. When installing projecting apparatus 4, insert second connecting pipe 12 with first connecting pipe 11 when holder 3 opens, connect second connecting pipe 12 one end with first connecting pipe 11 and set up to the slick and sly hemisphere face in surface, and set up protruding edge 7 near second connecting pipe 12 department at first connecting pipe 11, be favorable to the light first connecting pipe 11 of holding of operator, then will set up hemisphere face one end and insert in second connecting pipe 12, make installation projecting apparatus 4 more convenient.

Referring to fig. 2, in order to facilitate closing of the clamp 3, the fixing portion 31 is provided as a trapezoidal body. The area of one end face of the fixing part 31 inserted into the blind hole 21 (see fig. 1) is smaller than that of the other end face, and the blind hole 21 is matched with the fixing part 31, so that the fixing part 31 is inserted into the opening of one end face of the blind hole 21, which is smaller than the blind hole 21, so that the fixing part 31 can be more easily inserted into the blind hole 21.

Referring to fig. 2, the end surface of the fixing portion 31 is provided with a first magnetic member 81, as shown in fig. 1, one surface of the blind hole 21 contacting the fixing portion 31 is provided with a second magnetic member 82, and the first magnetic member 81 and the second magnetic member 82 attract each other, so that the fixing portion 31 can be more stably inserted into the blind hole 21, the fixing portion 31 cannot be rotated out of the blind hole 21, and the first connecting pipe 11 and the second connecting pipe 12 are stably connected to ensure the stability of the projector 4. Furthermore, two sides of the second connecting pipe 12, on which the clamping member 3 is disposed, are provided with insertion holes 9, the insertion holes 9 are fixedly connected with springs 10, and one ends of the springs 10, which are far away from the second connecting pipe 12, extend out of the insertion holes 9 and are fixedly connected with the clamping member 3. The spring 10 is always placed in a stretched state, so that the fixing portion 31 always passes through the through hole 22 under the elastic force of the spring 10, and the connection between the first connection pipe 11 and the second connection pipe 12 is more stable.

Referring to fig. 1, the connection pipe is made to be telescopic so that the height of the ceiling to which the projector 4 is mounted is different for different users or different occasions, which is a good solution. Three blind holes 21 are formed in the length direction of one end, connected with the second connecting pipe 12, of the first connecting pipe 11, fixing pieces are inserted into the different blind holes 21, the length of the first connecting pipe 11 extending out of the second connecting pipe 12 is inconsistent, and therefore the length of the support 1 is inconsistent, and the purpose of adjusting the height of the projector 4 is achieved. In the embodiment, three blind holes 21 are provided, and in actual production, different numbers of blind holes 21 can be provided according to different situations.

Referring to fig. 1, in order to better position the blind hole 21 when the first connecting pipe 11 is installed on the second connecting pipe 12, a plurality of first limiting members 131 are disposed on an outer wall of a position where the first connecting pipe 11 is connected to the second connecting pipe 12, the first limiting members 131 are disposed below the blind hole 21 and correspond to the blind holes 21 one to one, as shown in fig. 2, an elastic second limiting member 132 is disposed on an inner wall of one end of the second connecting pipe 12 connected to the first connecting pipe 11, and the first limiting member 131 is clamped to the second limiting member 132. When the first connecting pipe 11 is inserted into the second connecting pipe 12, the second limiting members 132 are sequentially clamped with the first limiting members 131 along with the insertion of the first connecting pipe 11, and when the second limiting members 132 are clamped with each first limiting member 131, the through holes 22 can be aligned with the blind holes 21 corresponding to the first limiting members 131, so that the blind holes 21 are positioned, the blind holes 21 and the through holes 22 are easily aligned, and the projector 4 is more convenient to install.

The implementation principle of the embodiment is as follows: when the projector 4 is installed, the second connecting pipe 12 is connected to the ceiling in a threaded mode, then the operator holds the handle part 6 with one hand to open the clamping piece 3, holds the first connecting pipe 11 with the other hand, inserts one end of the first connecting pipe 11 into the second connecting pipe 12, selects the blind hole 21 corresponding to the required installation height of the projector 4, aligns the blind hole 21 with the through hole 22, then releases the handle part 6, and the fixing part 31 penetrates through the through hole 22 and is inserted into the blind hole 21 after rotating to complete installation work.

The embodiment of this specific implementation mode is the preferred embodiment of the present invention, not limit according to this the utility model discloses a protection scope, so: all equivalent changes made according to the structure, shape and principle of the utility model are covered within the protection scope of the utility model.
