[0031] Specifically, in the embodiment, the magnetic base 10 is provided with a permanent magnet, and the magnetic switch 11 is rotatably arranged on the magnetic base 10 and fixedly connected with the permanent magnet. In this way, the magnetic attraction of the magnetic base 10 is adjusted by rotating the magnetic switch 11, so that it is adsorbed on the surface of a ferromagnetic object or removed from the ferromagnetic object. In addition, the first universal ball 20 is arranged at the top of the magnetic base 10. The bottom of the magnetic base 10 is provided with a sliding groove 12, so that the magnetic base 10 is slidably connected with the sliding rail on some equipment, and the position of the magnetic base 10 is more easily adjusted.

[0032] In the embodiment, the first rotary arm 30 is coaxially connected with a first connecting arm 31 at the end away from the second rotary arm 40, the first connecting arm 31 is threadedly connected with the first rotary arm 30, and the end of the first connecting arm 31 away from the first rotary arm 30 is rotatably arranged on the first universal ball 20. In addition, the second rotary arm 40 is coaxially connected with a second connecting arm 41 at the end away from the first rotary arm 30, the second connecting arm 41 is threadedly connected with the second rotary arm 40, and the end of the second connecting arm 41 away from the second rotary arm 40 is rotatably arranged with the second universal ball 21.

[0033] In this embodiment, the bidirectional rotary joint 50 includes a first rotating body 51, a second rotating body 52, a locking piston 54, and a locking nut 53. The first rotating body 51 and the second rotating body 52 are coaxially arranged. A nut 55 is provided at the end of the second rotating body 52 away from the first rotating body 51. The first rotating body 51 and the second rotating body 52 are connected by the locking piston 54 and the locking nut 53. The locking nut 53 passes through the first rotating body 51 and the second rotating body 52 and is threadedly connected to the nut 55. The first rotating body 51 is fixedly connected to the first rotating arm 30, and the second rotating body 52 is fixedly connected to the second rotating arm 40. It can be understood that by turning the locking nut 53, the locking or relative movement between the first rotating body 51 and the second rotating body 52 can be adjusted to facilitate the adjustment of the position of the second rotating arm 40.

[0034] Specifically, such as Figure 4 As shown, a gasket 56 is provided between the first rotating body 51 and the second rotating body 52, thus making the first rotating body 51 and the second rotating body 52 more securely fixed together. Additionally, a first limiting rod 32 is provided inside the first rotating arm 30, with a first inclined surface at one end. The first rotating body 51 has a first ramp corresponding to the first inclined surface of the first limiting rod 32. Furthermore, a second limiting rod 42 is provided inside the second rotating arm 40, with a second inclined surface at one end. The second rotating body 52 has a second ramp corresponding to the second inclined surface of the second limiting rod 42. During the user's tightening of the locking nut 53, the first rotating body 51 and the second rotating body 52 respectively compress and fix the first limiting rod 32 and the second limiting rod 42.

[0035] Furthermore, such as Figure 5 As shown, the bottom of the first connecting arm 32 is provided with a universal ball base adapted to the first universal ball 20, and the end of the first limiting rod 32 away from the first rotating body 51 is provided with a groove adapted to the shape of the first universal ball 20. When the first rotating body 51 presses against the first limiting rod 32, the first limiting rod 32 will move downward and press against the first universal ball 20, so that the groove of the first limiting rod 32 is squeezed into the first universal ball 20, and the first universal ball 20 is pressed and fixed by the groove under the pressure of the first limiting rod 32. Similarly, the cooperation between the second limiting rod 42 and the second universal ball 21 is the same as the cooperation between the first limiting rod 32 and the first universal ball 20, and will not be described again here.

[0036] Further, the clamping mechanism 60 of this embodiment includes a first connecting rod 61 and a second connecting rod 62. One end of the first connecting rod 61 is connected to the end of the second rotating arm 40 away from the first rotating arm 30 via the second universal ball joint 21. The other end of the first connecting rod 61 is hinged to one end of the second connecting rod 62. The end of the second connecting rod 62 away from the first connecting rod 61 is recessed inward to form the insertion part 64, and the clamping part 63 is provided on the second connecting rod 62. In this embodiment, a clamping groove is provided through the second connecting rod 62, and threaded through holes for threaded connection of the locking screw 65 are provided on both sides of the clamping groove. The clamping part 63 is a clamping groove. In addition, a ball groove for the second universal ball joint 21 to rotate is provided at the end of the second rotating arm 40 connected to the clamping mechanism 60, and notches are symmetrically provided on both sides of the ball groove. Furthermore, the insertion part 64 has a dovetail groove structure and is connected to the clamping groove. It can be understood that the clamping mechanism 60 is used to clamp precision instruments. When the connecting part of the precision instrument is inserted into the clamping part 63, the connecting part can be locked and fixed by the locking screw 65. Additionally, some precision instruments may have a dovetail portion at one end of the connecting part that matches the dovetail groove. In this way, the connecting part of the precision instrument can also achieve a quick connection when inserted into the dovetail groove of the clamping mechanism 60.

[0037] like Figure 7 As shown, an adjusting screw is also provided at the connection between the first link 61 and the second link 62. A spring is fitted onto the adjusting screw to provide cushioning. Tightening the adjusting screw changes the rigidity between the first link 61 and the second link 62. When the adjusting screw is fully tightened, the connection between the first link 61 and the second link 62 is the tightest, the rigidity is at its strongest, and the measurement fluctuation is more pronounced. Slightly loosening the adjusting screw allows adjustment of the rotation amplitude between the first link 61 and the second link 62, thereby adjusting the fluctuation amplitude of the measuring instrument and achieving fine-tuning.

[0038] Compared with traditional technologies, the magnetic support base of this invention, through the cooperation of the first universal ball joint 20, the first rotating arm 30, the second rotating arm 40, and the bidirectional rotary joint 50, as well as the cooperation of the second universal ball joint 21, the first connecting rod 61, and the second connecting rod 62, can achieve the effect of freely adjusting the direction, angle, and height. It also provides stable, high-precision positioning, and has a simple structure and is easy to operate, meeting the measurement and testing needs of various precision instruments. Furthermore, the magnetic support base of this invention, with the clamping part 63 and the insertion part 64, can be used to clamp various different precision instruments for measurement, and the clamping is secure.

[0039] The above-described embodiments only express several implementation manners of the utility model, the description is more specific and detailed, but can not therefore be understood as the limitation of the utility model magnetic support seat range. It should be pointed out that for ordinary skilled person in the art, without departing from the utility model concept, several deformations and improvements can be made, which belong to the protection scope of the utility model.
