Embodiment Construction
[0038]The present invention will be further described in detail below with reference to the examples and figures, but the embodiments of the present invention are not limited thereto.
[0039] Such as figure 1 As shown, a high-precision valve driver includes a housing 1, and a cylindrical cylindrical groove 2 is opened in the housing 1 along its length direction, and the cylindrical groove 2 forms an opening at one end of the housing 1. A hoisting hole 3 is provided on the outer wall of the housing 1 . A sleeve 4 is sleeved coaxially in the cylindrical groove 2 . The end of the sleeve 4 away from the opening of the housing 1 is the driving connection part, and the end close to the opening of the housing 1 is the clamping part. The driving connecting part is connected with a secondary helical gear set, and the inner wall of the clamping part is provided with a valve The shape of the valve stem matches the clamping groove 5. When in use, one end of the valve stem directly ext...
