Detailed Description
The present invention will be described in detail below with reference to the accompanying drawings in conjunction with embodiments. It should be noted that, in the present invention, the embodiments and features of the embodiments may be combined with each other without conflict. For convenience of description, the words "upper", "lower", "left" and "right" in the following description are used only to indicate the correspondence between the upper, lower, left and right directions of the drawings themselves, and do not limit the structure.
As shown in FIGS. 1-2, the utility model provides a pair of support fixing device includes support 1, support 1 includes a plurality of landing legs 11 and is used for fixing a plurality of bottom plate 12 of landing leg 11. The number of the supporting legs 11 is three, and the supporting legs are uniformly distributed on the bottom plate 12. The supporting legs 11 and the bottom plate 12 are screwed tightly by screw threads.
The support fixing device further comprises a locking seat 2 and a differential nut 3, the locking seat 2 comprises a body 21 and a locking cover plate 22, the body 21 is of a cylindrical structure with two open ends, the open end of the body is vertically arranged, the locking cover plate 22 is erected in an opening in the upper end of the body 21, and an opening in the lower end of the body 21 is in butt joint with the bottom plate 12.
