[0006] The support assembly includes base, the base is equipped with support frame above, the support frame includes the first support of being arranged above base, the second support is equipped in the first support, the third support is equipped in the second support, the first support and second support, the second support and third support between are all fixed by the second bolt and nut screwing, the third support is equipped with receiver body above, the third support top end is fixedly installed with screw rod, the receiver body bottom end is equipped with with screw rod matching screw sleeve;

[0007] The base side wall is equipped with multiple annular array distribution firm blocks, the firm block is close to base side and is fixedly installed with insert block, the base side wall is equipped with with insert block matching insertion slot, the insertion slot two sides inner wall is all equipped with storage groove, the storage groove is all equipped with positioning assembly.

[0008] By adopting the above technical scheme, when the device is used, the staff can store the support assembly and the receiver body in the box body for carrying, which is beneficial to improve the portability of the receiver body. After the staff arrives at the work site, the staff takes out the support assembly and the receiver body from the box body, places the base on the ground, and then assembles the support frame with the base. The support frame is assembled by the first support, the second support and the third support. The side walls of the first support and the second support are embedded with nuts. The second bolts penetrate the joint of the first support and the second support, the second support and the third support and are screwed with the nuts on the same side. Through the cooperation of the second bolts and the nuts, the first support and the second support, and the second support and the third support are locked, which is beneficial to support the receiver body. When the support assembly is assembled, the staff screws the screw sleeve installed at the bottom of the receiver body with the screw rod installed at the top of the third support, which can assemble the receiver body. Then, the staff engages the insertion block installed on one side of the stabilizing block with the insertion slot opened in the side wall of the base, which can assemble the stabilizing block and balance the support frame, which is beneficial to maintain the stability of the receiver body in use. The insertion slot is provided with a positioning assembly, which can position the insertion block and maintain the stability of the assembly of the stabilizing block and the base.

[0009] When the device is used, the staff takes out the insertion block installed on one side of the stabilizing block from the same side insertion slot, reversely rotates the receiver body, and then disengages the screw sleeve installed at the bottom of the receiver body from the screw rod, which can disassemble the receiver body. Then, the staff reversely rotates the second bolt, which loosens the connection between the first support and the second support, the second support and the third support, which is beneficial to fold the support frame later.

[0042] When the device is used, the staff can place the support assembly 2 and the receiver body 4 in the box 1 for storage, and the box 1 is used for carrying, which is beneficial to improve the portability of the receiver body 4. After the staff arrives at the work site, the staff takes out the support assembly 2 and the receiver body 4 from the box 1, places the base 21 on the ground, and then the staff places the support frame 22 above the base 21, so that the fixing block 2211 at the bottom of the support frame 22 is clamped with the fixing groove at the top end of the base 21. Through the clamping of the fixing block 2211 and the fixing groove, the support frame 22 is positioned and fixed. When the support frame 22 is positioned, the staff flips the support block 5, so that one side of the support block 5 is attached to the top of the base 21. By means of the first bolt 51 penetrating through the support block 5 and being screwed with the screw groove at the top end of the base 21, the support frame 22 and the base 21 can be assembled.

[0043] The support frame 22 is assembled by the first support 221, the second support 222 and the third support 223. The side walls of the first support 221 and the second support 222 are embedded with the nut 7. The second bolt 6 penetrates through the splicing portions of the first support 221 and the second support 222, the second support 222 and the third support 223 and is screwed with the nut 7 at the same side. By flipping the second support 222 and the third support 223, the first support 221 and the second support 222, the second support 222 and the third support 223 are locked through the cooperation of the second bolt 6 and the nut 7, which is convenient for subsequent support and stability of the receiver body 4.
