Description
Technical field
The utility model relates to a kind of minitype projection machine base supports more particularly to a kind of convenient for height and angular adjustment
Minitype projection machine base support.
Background technique
Minitype projection machine is the precision instrument for integrating light, mechanical, electrical complication system, compact, internal battery, In
Use process can put and watch at an arbitrary position, such as indoor spaces, travelling, encamp, occasion of going on business, thus increasingly by
Entertain the favor of user.
Minitype projection machine is generally required in use using base support, and small part minitype projection machine carries pedestal branch
Frame, but its amplitude of accommodation is little, and practicability is poor；Most of minitype projection machine does not carry base support, so user is taking
Also need to carry base support while band projector, the trip of user very inconvenient in this way, and may also user forget
Band projector bracket.
If for user when using minitype projection machine, generally there are between projector and curtain without base support
Problem that cannot be vertical, cannot get preferable picture projection, in fact it could happen that picture skew or projection image cannot be whole
It throws in curtain；If in addition carrying base support, in addition to because base support be individual components it is inconvenient to carry and other than,
Traditional base support is difficult to have both height and angle regulating function, is equally difficult to realize ideal drop shadow effect, and adjust
It is not very convenient.These problems have seriously affected the usage experience of minitype projection machine.
Utility model content
The purpose of this utility model be that provide one kind to solve the above-mentioned problems can be close with minitype projection machine
In conjunction with convenient for height and angular adjustment minitype projection machine base support.
The utility model achieves the above object through the following technical schemes:
A kind of minitype projection machine base support convenient for height and angular adjustment, including weight bearing foundation further include that lifting connects
