[0002] The wire-pulling displacement sensor is also called a draw-wire sensor, a draw-wire electronic ruler, and a draw-wire encoder; the wire-pulling displacement sensor is an ingenious structure of a linear displacement sensor, which fully combines the advantages of an angle sensor and a linear displacement sensor, and becomes a sensor with a small installation size, a compact structure, a large measurement stroke, and high precision. The stroke ranges from several hundred millimeters to dozens of meters; in terms of operation, the draw-wire displacement sensor is installed at a fixed position, the draw-wire is tied to a moving object, the linear movement of the draw-wire is aligned with the movement axis of the moving object. When the movement occurs, the draw-wire extends and contracts, and an internal spring ensures that the tension of the draw-wire remains unchanged. The threaded hub drives the precision rotary inductor to rotate, and outputs an electrical signal proportional to the moving distance of the draw-wire. By measuring the output signal, the displacement, direction or speed of the moving object can be obtained.
[0003] The traditional fixing method of the wire-pulling displacement sensor is too simple, resulting in the problem that the wire-pulling displacement sensor is prone to looseness during specific use, and the fixing device for the wire-pulling displacement sensor can often only fix sensors of a single size, with low applicability; in addition, when the wire-pulling displacement sensor is installed, it cannot be rotated anymore, resulting in the fixed direction of the wire outlet end of the wire-pulling displacement sensor, and it is not flexible enough to use; for this reason, we design a fixing device applied to the wire-pulling displacement sensor to solve the above technical problems.

In this device, the clamping member 2 is a common stainless steel clamp or a clamp structure on the market. The fixing connecting member 3 can be fixed by bolts and nuts. This is prior art and will not be elaborated in detail. On both adjacent edges of the top of the fixing plate 5, side plates 7 are provided. The two side plates 7 are connected as a whole. The side plates 7 and the fixing plate 5 are integrally formed. A chute 6 is penetrated through the side plates 7.

Limiting grooves 13 are symmetrically opened on the inner walls of the upper and lower sides of the chute 6. A limiting block 14 is slidably arranged in the limiting groove 13. A sliding block 9 is connected between the two limiting blocks 14. On one side surface of the sliding block 9 close to the center of the fixing plate 5, a fixing block 15 is provided. On the other side surface of the sliding block 9 at the bottom, a connecting block 10 is provided. Both the fixing block 15 and the connecting block 10 are slidably arranged in the chute 6. On the side surface of the connecting block 10 away from the sliding block 9, a vertical plate 11 is provided. On the other side surface of the vertical plate 11, a push button 12 is provided. The vertical plate 11 is slidably arranged on the outer surface of the fixing plate 5.
