[0023] The following is combined with Figure 1-5 The technical solutions in the embodiments of the present invention are clearly and completely described. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of them. All other embodiments derived by persons of ordinary skill in the art based on the embodiments of the present invention without creative effort shall fall within the scope of protection of the present invention.

[0024] In the description of the present invention, it should be understood that the terms "longitudinal", "transverse", "up", "down", "front", "back", "left", "right", "vertical", "horizontal", "top", "bottom", "inside", "outside", etc., indicating the orientation or position relationship, are based on the orientation or position relationship shown in the accompanying drawings, and are only for the convenience of describing the present invention, and do not indicate or imply that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation. Therefore, they should not be understood as limitations on the present invention.

[0025] A retractable measuring ruler comprises a fixed rod 1, a first movable rod 2, and a second movable rod 3. The fixed rod 1 and the first movable rod 2 are sleeve structures. The first movable rod 2 is sleeved in the fixed rod 1, and the second movable rod 3 is sleeved in the first movable rod 2. The fixed rod 1, the first movable rod 2, and the second movable rod 3 are all provided with measuring markings 8 on the outside, which can measure the length of the cable 11. The tops of the fixed rod 1 and the first movable rod 2 are both provided with a slide groove 6 and a cavity 14. The slide groove 6 is located between the fixed rod 1 and the first movable rod 2. On the outside of the movable rod 2, the cavity 14 is located inside the fixed rod 1 and the first movable rod 2. The cavity 14 is connected to the slide groove 6. The same locking mechanism 7 is installed in the cavity 14 and the slide groove 6. The bottom of the fixed rod 1 and the top of the second movable rod 3 are both provided with a first groove 4. A wire clamp 5 is rotatably installed inside the first groove 4. A plurality of slots 51 are evenly arranged on the wire clamp 5. The cable 11 is installed in two slots 51. A wire clamp 10 is installed in the middle of the cable 11, which can cut the cable 11 to the same length.

[0026] The locking mechanism 7 includes a slider 701, a movable column 704, a spring 705, and a block 706. The slider 701 is slidably installed in the slide groove 6, the movable column 704 is slidably installed in the cavity 14 and one end extends into the slide groove 6, the block 706 is installed at one end of the movable column 704, and the spring 705 is installed on the periphery of the movable column 704, between the block 706 and the cavity 14. By sliding the slider 701 upward, the slider 701 squeezes the movable column 704, and the movable column 704 drives the block 706 to move inward to fix the first movable rod 2 or the second movable rod 3.

[0027] The slider 701 is externally mounted with a plurality of raised strips 702, which increase the friction of the slider 701. Guide strips 703 are mounted on both sides of the slider 701. The chute 6 is provided with strip grooves that cooperate with the guide strips 703, facilitating the movement of the slider 701. Guide blocks 9 are mounted on the bottoms of the first and second movable rods 2 and 3, and guide grooves 13 that cooperate with the guide blocks 9 are provided inside the fixed rod 1 and the first movable rod 2. This limits the position of the first and second movable rods 2 and 3, preventing separation between the fixed rod 1 and the first and second movable rods 2 and 3, and ensuring operational stability.

[0028] A second groove is formed inside the first groove 4, and a support rod 12 is rotatably mounted inside the second groove. The support rod 12 can support the wire gripper 5, thereby ensuring the stability of the wire gripper 5. There are multiple first grooves 4, and the number of wire grippers 5 corresponds to the number of first grooves 4. The size of each wire gripper 5 is different, so that cables 11 of different sizes can be cut, expanding the range of use.

[0029] The above content is merely an example and explanation of the structure of the present utility model. Technicians in this technical field may make various modifications or additions to the specific embodiments described or replace them in a similar manner. As long as they do not deviate from the structure of the utility model or exceed the scope defined by the claims, they should all fall within the scope of protection of the present utility model.
