As a preferred solution, scales are provided on the edges of the first arc-shaped chute and the second arc-shaped chute.

Further, compression nuts are sheathed on the first stud and the second stud.

When the adjustable nozzle fixing device is in use, loosen the nut connecting the vertical plate of the main support and the vertical plate of the auxiliary support, and then lock the nut after rotating the L-shaped auxiliary support to a predetermined angle, so as to change the angle of the nozzle in the axial direction. Loosen the compression nut on the first stud, rotate the main bracket to a predetermined angle and then lock the compression nut to realize the radial angle change of the nozzle. At the same time, the scales of the corresponding positions of the first stud and the first nut during the moving process are observed at any time, so that the adjustment process is more accurate.

Detailed ways

Below in conjunction with accompanying drawing and embodiment the utility model is further described.

Embodiment: An adjustable nozzle fixing device as shown in FIG. The main support horizontal plate 2.1 on the top surface is composed of the main support vertical plate 2.2 vertically arranged along the side edge of the main support horizontal plate 2.1, and is characterized in that: it also includes an L-shaped secondary support 3 arranged on the main support vertical plate 2.2, Described L-shaped secondary support 3 is made up of secondary support vertical plate 3.2 that is arranged on the inner side of L main support vertical plate 2.2 and the secondary support horizontal plate 3.1 that is vertically arranged on the side edge of secondary support vertical plate 3.2 horizontal direction. A first arc-shaped chute 4 is horizontally opened on the horizontal plate 2.1 of the main support, and a first stud 6 is provided at a position corresponding to the middle part of the first arc-shaped chute 4 of the base 1, and the first arc-shaped chute 4 The base 1 corresponding to the apex of the fan-shaped area is provided with a second stud 7 whose top passes through the horizontal plate 2.1 of the main support. The first stud 6 and the second stud 7 are sleeved with compression nuts 10 .
