Preferably, the supporting leg subassembly includes first connecting ball and gasket, in first connecting ball slip joint and the cylinder connection shell, and first connecting ball bottom is fixed with the telescopic link, telescopic link bottom screw thread has cup jointed the telescope tube, the telescope tube bottom is fixed with the second and connects the ball, and connects ball and gasket top slip joint through the second, telescopic link top outside threaded connection has the cutting ferrule, and cutting ferrule and cylinder connection shell outside sliding connection, realizes adjusting the support of projecting apparatus body through the supporting leg subassembly.
Preferably, the adjusting plate convenient for the telescopic sleeve to rotate is fixed on the outer side of the top of the telescopic sleeve, and the telescopic sleeve can rotate more conveniently through the adjusting plate.
Preferably, the bottom of the gasket is made of rubber, and the gasket made of rubber has stronger adsorption force.
Preferably, the adjusting plate and the clamping sleeve are provided with anti-slip lines on the outer sides, so that friction force is increased, and the adjusting plate and the clamping sleeve can rotate more conveniently.
Compared with the prior art, the beneficial effects of the utility model are that:
the utility model discloses when carrying out the projection, if throw picture and curtain crooked phenomenon all around, at this moment, earlier through the cutting ferrule of unscrewing in two supporting leg subassemblies, the rethread rotates the regulating plate, makes the outside removal of flexible cover to realize the angle modulation of projecting apparatus body one end, finely tune throwing the picture, can also satisfy the local use of unevenness on ground through the length of adjusting two supporting leg subassemblies simultaneously.

Detailed Description
The technical solutions in the embodiments of the present invention will be described clearly and completely with reference to the accompanying drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only some embodiments of the present invention, not all embodiments. Based on the embodiments in the present invention, all other embodiments obtained by a person skilled in the art without creative work belong to the protection scope of the present invention.
Referring to fig. 1-2, a projection device for home theater in the figure includes a projector body 1, a spherical boss 2 is fixed at the tail end of the bottom of the projector body 1, the spherical boss 2 can effectively play a supporting role, a cylindrical connecting shell 3 is fixed at the front end of the bottom, a supporting leg assembly 4 for adjusting the projection angle of the projector body 1 is installed in the cylindrical connecting shell 3, the supporting leg assembly 4 is used for supporting and adjusting the projector body 1, and the projected picture has wider applicability.
The supporting leg assembly 4 comprises a first connecting ball 5 and a gasket 6, the first connecting ball 5 is slidably clamped in the cylindrical connecting shell 3, a telescopic rod 7 is fixed at the bottom of the first connecting ball 5, a telescopic sleeve 8 is sleeved at the bottom end of the telescopic rod 7 in a threaded manner, a second connecting ball 9 is fixed at the bottom of the telescopic sleeve 8 and is slidably clamped with the top of the gasket 6 through the second connecting ball 9, a clamping sleeve 10 is connected to the outer side of the top of the telescopic rod 7 in a threaded manner, the clamping sleeve 10 is slidably connected to the outer side of the cylindrical connecting shell 3 in a threaded manner, and the telescopic rod 7 is connected with the telescopic sleeve 8 in a threaded manner, so that the telescopic sleeve 8 is moved on the telescopic rod 7, the length is adjusted, and the adjusting direction is wider due to multi-angle rotation of the first connecting ball 5 and the second connecting ball 9;
