DETAILED DESCRIPTION

[0025] The technical scheme of the utility model will be further illustrated below by specific embodiments in connection with the drawings.

[0026] As Figures 1-2 The utility model discloses a mounting fixed seat for installing line instrument and horizontal adjusting mechanism 200, and it is characterized in that, the horizontal adjusting mechanism 200 is fixed on the mounting fixed seat, and it includes:

[0027] A horizontal crossbar 202 is arranged horizontally;

[0028] A sliding sleeve 204 is slidably arranged on the crossbar 202, and a mounting fixing base is fixed to the bottom of the sliding sleeve 204;

[0029] A fixed arm 206 and a movable arm 208 are arranged above the crossbar 202, and the clamping distance between the fixed arm 206 and the movable arm 208 is changed by horizontally moving the movable arm 208 on the crossbar 202.

[0030] As a further improvement of the utility model, the sliding sleeve 204 is provided with a first through hole 210 with a vertical dimension greater than a horizontal dimension and a second through hole 212 with a horizontal dimension greater than a vertical dimension, and the sliding sleeve 204 is slidably arranged on the crossbar 202 through the first through hole 210 or the second through hole 212.

[0031] As a further improvement of the utility model,

[0032] A horizontal through mounting hole is arranged on the side wall of the first through hole 210 and / or the second through hole 212;

[0033] A first adjusting rod 216 with one end penetrating through the mounting hole is arranged in the mounting hole, the first adjusting rod 216 is arranged horizontally, and a threaded section with external threads is arranged on the first adjusting rod 216;

[0034] A nut 218 is threadedly matched with the threaded section;

[0035] A limiting sleeve 220 is arranged for limiting the circumferential rotation degree of freedom of the nut 218, and the limiting sleeve 220 is fixed to the sliding sleeve 204 or integrally arranged with the sliding sleeve 204.

[0036] As a further improvement of the utility model, the movable arm 208 is provided with:
