Support frame convenient for adjusting embedded pipe

The invention provides a support frame convenient for adjusting an embedded pipe, relates to the field of water conservancy and hydropower construction, and aims to solve the problems that the original support frame is not accurate enough in adjusting the size of the mounting angle of the embedded pipe and cannot adjust and change the structure according to actual use requirements, so that the service life is shortened, and the construction cost is reduced. The device comprises a frame which is in a hollow cuboid shape and a pair of left sliding blocks, and the pair of left sliding blocks are correspondingly installed on the left side end face of the frame. The two inserting rods are installed on the inner sides of the centers of the two left sliding blocks in a penetrating mode correspondingly, and each inserting rod is composed of a cone-shaped structure and a cylindrical structure; the right sliding blocks are correspondingly installed on the right side end face of the frame. The effect of gradually adjust
