The clip 71 is fixedly held by the clip 71, and finally the detector 83 is embedded in the abutting head 73 for detecting through the detector 83.

Since the size of the cylinder 8 is quite large, the distance between the rod 82 and the cylinder 81 is also different. However, the clip 71 of the detector jig and the abutting head 73 cannot be mutually Stretching or bending, when mounted on a cylinder 8 of other sizes, it is often impossible to use a detector fixture of the same specification, since the abutting head 73 is not exactly flat against the cylinder 81, causing the detector 83 The detection cannot be accurately performed, and the detection accuracy is lowered, so that a detector fixture is generally not applicable to the cylinders 8 of various sizes.

In addition, an inductive switch with a movable fixing jig disclosed in the patent of the mainland certificate number CN201039113Y includes an outer casing body, a clamping arm, and a fastening screw. The outer casing is cylindrical and can sufficiently abut against the cylinder, and is provided with the detector, the outer casing has an extension portion and a pressing portion. The extension portion and the clamp arm are tightly coupled to each other through two screws, and the pressing portion cooperates with the clamp arm to clamp the pull rod. The fastening screw directly locks the lever to prevent slippage.

The main clamping body cooperates with the clamping arm to clamp the pulling rod. The groove body abuts against the cylinder body and has a rib which is cylindrical and can be correspondingly clamped by the main body, and the main body and the rib are closely matched with each other through two screws. When the screw is loose, the main body and the rib are relatively rotatable and movable, and when the screws are screwed, the main body and the rib are fixed to each other.

Through the above two designs, the fixing bracket can be attached to the cylinder when it is mounted on other cylinders. However, the fixing bracket has a large number of parts, which is not advantageous for assembly and disassembly. In addition, the above design may be due to the negligence of the assembly, and the fixing bracket is locked when the fixing bracket is not directly attached to the cylinder, and the fixing bracket is not flatly attached to the cylinder and is not easily visible to the naked eye. , which in turn affects the accuracy of future measurements. In addition, the fixing bracket can not smoothly sway against the cylinder due to the shaking or vibration generated during the operation of the cylinder, thereby affecting the accuracy of the measurement.
