Rotating parts 3 are provided on the inner walls on both sides of the machine head 2, and transfer parts 4 cooperating with the rotating parts 3 are provided on both sides of the support unit 1. Manually adjust the machine head 2 to make it pitch and rotate, and the machine head 2 drives the rotating part 3 to rotate around the transfer part 4; specifically, the support unit 1 includes at least two rod bodies that can be rotatably folded.

[0023] The rotating part 3 and the transfer part 4 are connected by a screw 5; specifically, the rotating part 3 includes a nut 31, a metal gasket 32, a corner fixing metal part 33 and a rubber gasket 34 sleeved on the screw 5 in sequence from the inside to the outside. The top of the corner fixing metal part 33 is fixedly connected to the inner wall of the machine head 2 by screws.

[0024] The transfer part 4 includes a transfer member 41 and a cover sheet 42 covering and inserted on the outside of the transfer member 41; specifically, a groove 411 for limiting and installing the screw 5 is provided in the transfer member 41, and a boss 51 that abuts and limits against the groove 411 is provided at the outer end of the screw 5.

[0025] The rubber gasket 34 is in contact with the inner surface of the adapter 4, and the rubber gasket 34 rotates around the screw 5 to generate friction with the adapter 4; specifically, the rubber gasket 34 is in contact with the inner surface of the adapter 41, and the friction generated realizes the angular positioning of the head 2 after rotation.

[0026] The adapter 41 is provided with a hinge portion 6 on the side thereof, and a rotating member 7 is rotatably provided on the hinge portion 6 .

[0029] The working principle of the present invention is as follows: the machine head 2 is manually adjusted to pitch and rotate, and the machine head 2 drives the rotating part 3 and the screw 5 to rotate around the adapter 4. The boss 51 at the outer end of the screw 5 rotates in the groove 411 of the adapter 41, and the rubber gasket 34 fits and rotates with the inner surface of the adapter 41. The relative rotation of the rubber gasket 34 and the adapter 41 generates friction. When the machine head 2 is adjusted to the angle desired by the user, manual adjustment is stopped, and the machine head 2 achieves angular positioning under the action of the friction generated by the rubber gasket 34.

[0030] The rotating rod 12 is bent to make the rotating member 7 rotate around the hinge portion 6, so that the rod body is manually rotated and retracted, thereby achieving the purpose of storage.

[0031] The advantages of the present invention are: by manually adjusting the angle of the machine head 2, the machine head 2 can be pitched and rotated around the rotating part 3, and the angle positioning of the machine head 2 after rotation is achieved through the friction between the rubber gasket 34 and the adapter 41. The operation is simple, the internal parts are simplified, and the installation is convenient; the manually rotatable and retractable support unit 1 facilitates storage.
