A fixed axis gear 45 is provided at the connection, and a gear locking bolt 46 is sleeved on the outer ring of the light rod 42. The screws 41 of the upper leg 4 and the lower leg 5 are screwed into the upper sleeve 2 and the lower sleeve 3 respectively, and the overall height of the upper leg 4 and the lower leg 5 and the upper sleeve 2 and the lower sleeve 3 is adjusted by screwing in the screws 41. The gear locking bolt 46 is embedded in the fixed axis gear 45 to lock the relative positions of the upper leg 4 and the lower leg 5 and the upper sleeve 2 and the lower sleeve 3.

[0011] like Figure 3 As shown, preferably, the gear locking bolt 46 is a collar, and the inner ring of the collar is symmetrically provided with convex teeth 47 matching the gear 45. The upper and lower legs are locked with the upper sleeve and the lower sleeve by embedding the convex teeth into the fixed axis gear.
