[0019] The technical solutions in the embodiments of the present application will be clearly and completely described below in conjunction with the drawings in the embodiments of the present application. Obviously, the described embodiments are only part of the embodiments of the present application, rather than all of the embodiments.

[0020] In the description of this application, it should be understood that the terms "upper", "lower", "front", "back", "left", "right", "top", "bottom", "inside", "outside" and the like indicate directions or positional relationships based on the attached Figure 1 , and is only for the convenience of describing the present application and simplifying the description, and does not indicate or imply that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore cannot be understood as limiting the present application.

[0021] like Figure 1-3 As shown, an adjustable locking rod comprises a telescopic rod 1, a clamp 2, and a sleeve rod 3. The first end of the telescopic rod 1 is provided with the clamp 2, the sleeve rod 3 has a slot adapted to the size of the telescopic rod 1, the second end of the telescopic rod 1 is arranged in the slot and can be telescoped in the slot, a plurality of positioning holes 4 are arranged along the length direction near the second end of the telescopic rod 1, a positioning assembly is provided on the sleeve rod 3, the positioning assembly has a positioning pin 5 and a positioning frame 6, and can push the positioning pin 5 to be inserted into the positioning hole 4.

[0022] Specifically, the telescopic rod 1 is telescoped and adjusted in length in the slide groove of the sleeve rod 3. When telescoping, the positioning frame 6 is driven to deflect so that the positioning pin 5 is synchronously deflected and pulled out of the positioning hole 4. When fixing, the positioning frame 6 is pushed to drive the positioning pin 5 to be inserted into the positioning hole 4, thereby positioning the position of the telescopic rod 1.

[0023] Furthermore, the positioning assembly also has an elastic member 7, the positioning frame 6 is a rectangular frame structure, and the sleeve rod 3 passes through the hollow part of the positioning frame 6, the positioning pin 5 is fixedly connected to the bottom of the positioning frame 6, the elastic member 7 is arranged between the top of the positioning frame 6 and the sleeve rod 3, and can drive the positioning pin 5 to be inserted into the positioning hole 4 by pushing the positioning frame 6, and the sleeve rod 3 is provided with an opening for the positioning pin 5 to pass through.

[0024] Specifically, the positioning frame 6 is pressed to deflect it and the elastic member 7 is squeezed. When the pressure is released, the elastic force of the elastic member 7 is restored to push the positioning frame 6 to return to its original position, and the positioning pin 5 is inserted into the positioning hole 4 through the opening, thereby fixing the position of the telescopic rod 1.

[0025] Furthermore, a slider 10 is fixedly connected to the side of the sleeve rod 3 , a slide groove 9 adapted to the size of the slider 10 is opened on the positioning frame 6 , and the slide groove 9 is arranged along the offset direction of the positioning frame 6 , and the slider 10 is slidably matched with the positioning frame 6 .

[0026] Specifically, when the positioning frame 6 is offset, the slider 10 slides and cooperates with the positioning frame 6 inside the slide groove 9. At this time, the slider 10 keeps the offset of the positioning frame 6 linear to ensure stability.

[0027] Furthermore, a pressing handle 8 is fixedly provided on the top of the positioning frame 6 to facilitate the operator to press the positioning frame 6 .

[0028] Furthermore, the positioning pin 5 can be a cylindrical body or a rectangular cylinder and can be inserted into the positioning hole 4 .

[0029] Furthermore, the cross-sections of the telescopic rod 1 and the sleeve rod 3 are rectangular or circular, and the telescopic rod 1 can be telescoped in the slot on the sleeve rod 3 .

[0030] Furthermore, the elastic member 7 is a spring that can restore its elasticity after being squeezed, and then push the positioning frame 6 .

[0031] In the above structure, the clamp 2 can be used to clamp the wire. When the length needs to be adjusted, the positioning frame 6 is pressed to drive the positioning pin 5 to come out of the positioning hole 4, and then the telescopic rod 1 is telescoped in the sleeve rod 3 to adjust the length. After adjustment, the positioning frame 6 is released, and then the elastic member 7 squeezed by the positioning frame 6 restores the elastic force to push the positioning frame 6 back to its original position. At the same time, the positioning pin 5 moves with the positioning frame 6, so that the positioning pin 5 is inserted into the positioning hole 4 to fix the position of the telescopic rod 1.

[0032] The above shows and describes the basic principles, main features and advantages of the present application. Those skilled in the art should understand that the present application is not limited by the above embodiments. The above embodiments and descriptions are only for explaining the principles of the present application. Without departing from the spirit and scope of the present application, the present application may have various changes and improvements, which fall within the scope of the present application to be protected. The scope of protection claimed in the present application is defined by the attached claims and their equivalents.
