[0023] Embodiment

[0024] As Figures 1-4 shown, an angle-adjustable wrench includes a clamping plate 1, a grip rod 3 and a connecting assembly. One end of the clamping plate 1 is provided with a bolt hole 101. When disassembling and assembling a bolt, the bolt is inserted into the bolt hole 101, and the clamping plate 1 is rotated parallelly to achieve the effect of adjusting the tightness of the bolt. The clamping plate 1 is rotatably connected to one side of the grip rod 3. One end of the clamping plate 1 is provided with a rotating seat 2, and a plurality of rotating grooves 21 are provided on the rotating seat 2. A plurality of connecting pieces 31 are provided at one end of the grip rod 3. The connecting pieces 31 are arranged in the rotating grooves 21, and the clamping plate 1 and the grip rod 3 rotate around the rotating seat 2 as the center.

[0025] As Figures 1-5 shown, the connecting assembly includes a limiting seat 5, a connecting seat 4 and a limiting plate structure. The connecting seat 4 is arranged at one end of the clamping plate 1, and the limiting seat 5 is arranged on the grip rod 3. At least one group of connecting assemblies is provided. A connecting hole I 41 is provided on the connecting seat 4, a connecting hole II 51 is provided on the limiting seat 5, a flexible rope member 6 is fixedly arranged in the connecting seat 4, the flexible rope member 6 extends out from the connecting hole I 41, passes through the limiting seat 5, and extends into the connecting hole II 51. When the clamping plate 1 rotates, it drives the flexible rope member 6 to slide in the limiting seat 5, and adjusting the length of the flexible rope member 6 can adjust the rotation angle of the clamping plate 1.

[0026] As Figure 1 、 4As shown in FIGS. 5, the limiting plate structure is slidably arranged on the grip rod 3. One end of the limiting plate structure can extend into the limiting seat 5. A clamping groove 32 is arranged on one side of the grip rod 3. The limiting plate structure is slidably arranged in the clamping groove 32. The limiting plate structure includes a limiting plate 7 and a limiting rod 71. A spring 72 is arranged in the clamping groove 32. The limiting plate 7 is arranged in the clamping groove 32 and connected to the spring 72. The limiting rod 71 is arranged on one side of the limiting plate 7. A one-sided through limiting hole 52 is arranged on the limiting seat 5. The limiting hole 52 is arranged on the side close to the limiting plate 7. The limiting rod 71 extends into the limiting hole 52. When the limiting plate 7 extends into the clamping groove 32, the limiting rod 71 synchronously extends into the limiting hole 52 to tightly press the flexible rope member 6 and restrict the sliding of the flexible rope member 6.

[0027] As Figures 1-5 shown, a support 8 is arranged at one end of the grip rod 3. A storage wheel 81 is rotatably arranged on the support 8. One end of the flexible rope member 6 is wound around the storage wheel 81. A rocker 82 is arranged at one end of the storage wheel 81. In the initial situation, most of the flexible rope member 6 is wound around the storage wheel 81. When it is necessary to adjust the tightness of the bolt, a person holds the grip rod 3. There is a certain angle between the grip rod 3 and the clamping plate 1. Then, the clamping plate 1 is placed on the upper part of the bolt, and the flexible rope member 6 is slowly released. The clamping plate 1 rotates by gravity and fits with the plate member until the bolt is completely inserted into the bolt hole 101. Then, the grip rod 3 can be rotated to realize the disassembly and assembly of the bolt. During the rotation process, part of the flexible rope member 6 leaves the storage wheel 81. The palm presses the limiting plate 7 to make the limiting rod 71 extend into the limiting hole 52 to restrict the movement of the flexible rope member 6 and fix the angle of the clamping plate 1. Holding the grip rod 3 and rotating can adjust the tightness of the bolt. After the adjustment is completed, the hand is released from the grip rod 3. The spring 72 resets to drive the limiting plate 7 to reset. The limiting rod 71 slides out to one side of the limiting hole 52. The rocker 82 is rotated to wind the flexible rope member 6 back onto the storage wheel 81 and drive the clamping plate 1 to reset.

[0028] The above are only the preferred embodiments of the present invention and are not used to limit the present invention. For those skilled in the art, the present invention can have various changes and modifications. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principle of the present invention shall be included in the protection scope of the present invention.
