[0032] In an embodiment of the utility model, the U-shaped bracket 310 can rotate in the first direction relative to the base 320, and the first direction here can be regarded as a horizontal direction, so that the projection angle of the projector can be adjusted in the horizontal direction; the shell 10 can rotate in the second direction relative to the U-shaped bracket 310, and the second direction here is a direction perpendicular to the first direction, that is, it can be understood as a vertical direction, so that the projection angle of the projector can be adjusted in the vertical direction, and then the projection angle of the projector can be adjusted in multiple directions through the gimbal bracket 30, thereby improving the user experience of using the projector.

[0033] Please combine Figure 3-4 , in other preferred embodiments of the utility model.

[0034] Furthermore, the rotation angle range of the housing 10 relative to the U-shaped bracket 310 is no more than 270 degrees. That is, the rotation range of the housing 10 in the U-shaped groove of the U-shaped bracket 310 is no more than 270 degrees. This 270-degree range can ensure that the projector can achieve a larger range of projection and improve the use quality of the projector.

[0035] Furthermore, the U-shaped bracket 310 can rotate 360 ​​degrees relative to the base 320. That is, the U-shaped bracket 310 can rotate 360 ​​degrees without dead angle relative to the base 320, and the combination of the rotation of the housing 10 relative to the U-shaped bracket 310 can ensure that the projector can achieve a wide range of projection angle adjustment in multiple directions, further improving the use quality of the projector.

[0036] In addition, the pan / tilt bracket 30 further includes a rotating shaft 330, and both ends of the rotating shaft 330 are respectively connected to the top end of the U-shaped bracket 310;

[0037] The housing 10 is disposed on the rotating shaft 330 and can rotate relative to the rotating shaft 330 .

The position of the touch area 130 on the housing 10 is exactly opposite to the position of the touch panel 230, so that the operation control of the projector can be realized by touching the touch area 130.

[0047] Furthermore, a plurality of holes 130 are arranged in an array on the housing 10 opposite to the side plate 3102 .

[0048] Specifically, a plurality of holes 130 are provided on the sides of the housing 10 on both sides of the projection window 110 .
