For those skilled in the art, the present application can be implemented without some of these specific details. The following description of the embodiments is only to provide a better understanding of the present application by showing examples of the present application.

[0020] As Figure 1 , Figure 2 and Figure 3As shown, the utility model provides a kind of power transmission cable fixing device technical scheme: including a fixed seat 1, the fixed seat 1 front is provided with adjustment recess 11.Adjustment recess 11 is provided with clamping fixed mechanism, and this mechanism includes two groups of upper clamping wheel 22 and a lower clamping wheel 23.The outer wall of upper clamping wheel 22 and lower clamping wheel 23 is provided with recess, for clamping power transmission cable.

[0021] As Figure 2 Shown, adjustment recess 11 is provided with three groups of self-adapting sliding slot 111, and each self-adapting sliding slot 111 is slidably connected with sliding block 24.Upper clamping wheel 22 and lower clamping wheel 23 are connected with clamping wheel shaft 21, and clamping wheel shaft 21 is connected with sliding block 24, and upper clamping wheel 22, lower clamping wheel 23 and clamping wheel shaft 21 are rotatably connected.

[0022] As Figure 3 Shown, the bottom wall of sliding block 24 at the back of upper clamping wheel 22 is installed with self-adapting spring 25 between self-adapting sliding slot 111.Also, the top wall of sliding block 24 at the back of lower clamping wheel 23 is also installed with self-adapting spring 25 between self-adapting sliding slot 111.

[0023] In practical application, when power transmission cable needs to be fixed, operator places cable between the recess of upper clamping wheel 22 and lower clamping wheel 23.Because of the design of self-adapting sliding slot 111 and sliding block 24, the device can automatically adjust clamping force according to the diameter of cable.When the diameter of cable is larger, sliding block 24 moves inward under the action of self-adapting spring 25, and increases clamping force;when the diameter of cable is smaller, sliding block 24 moves outward, and reduces clamping force.In this way, the device can adapt to different specifications of cable, and ensure the stable fixation of cable.

[0024] In addition, the setting of self-adapting spring 25 enables the device to provide continuous clamping force when facing cable vibration, effectively prevents cable from loosening or falling off, thereby improving the stability and safety of power transmission.
