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.
Example 1
Referring to fig. 1 to 3, in embodiment 1 of the present invention, the device includes a mechanical arm 4, a control box 5, a motor 6, a bevel gear disc 7, a screw 3, a mounting seat 1, a threaded sleeve 9, a mechanical seat 12, and a mechanical arm 13; the outer sides of the upper end and the lower end of the threaded sleeve 9 are fixedly connected with bearing seats 10, the bearing seats 10 are fixedly connected inside the control box 5, and the outer side of the middle part of the threaded sleeve 9 is fixedly connected with a transmission gear 8; a main motor 6 is fixedly connected in the control box 5, a bevel gear disc 7 is fixedly connected at the front section of the motor 6, and the upper side of the bevel gear disc 7 is meshed with a transmission gear 8; two ends of the screw rod 3 are fixedly connected with a locking sleeve 2, the locking sleeve 2 is fixedly connected to the middle of the mounting seat 1, two sides of the mounting seat 1 are fixedly connected with a fixing sleeve 16 which is in the same direction as the locking sleeve 2, and a limiting rod 15 of the parallel screw rod 3 is fixedly connected in the threaded sleeve 9.
According to the device, the limiting rod 15 and the screw 3 penetrate through the control seat and are arranged in the corresponding fixing sleeve 16 and the corresponding locking sleeve 2 on the mounting seat 1, the mounting seats 1 at two ends, the limiting rod 15 and the screw 3 form a fixed relation, and then the mechanical seat 12 and the mechanical arm 13 are arranged, so that the height of the mechanical arm 13 can be controlled through the screw 3.
And a positioning sleeve 11 is fixedly connected in the control box 5 below the threaded sleeve 9, and the positioning sleeve 11 is sleeved on the screw rod 3 in a sliding manner. And a mechanical arm 4 is fixedly connected to the side surface of the control box 5. And a sliding sleeve 14 penetrating through the control box 5 is vertically and fixedly connected in the control box 5, and the sliding sleeve 14 is positioned on two sides of the threaded sleeve 9 and is parallel to the threaded sleeve 9. The limiting rod 15 penetrates through the sliding sleeve 14 and is in sliding fit with the sliding sleeve 14. The bottom of the mounting seat 1 is fixedly connected with a mechanical seat 12, and a mechanical arm 13 is fixedly connected below the mechanical seat 12. The teeth of the bevel gear disc 7 are radial from the center of the circle to the outside, and the bevel gear disc 7 is a plane gear.
