Detailed Implementation

[0021] The present application will be further described in detail below with reference to the accompanying drawings.

[0022] Reference Figures 1-3This application provides a convenient metal chain installation and disassembly tool, including a handheld frame 1. A threaded cylinder 3 is fixedly connected to the upper part of one end of the handheld frame 1. A threaded fixing cylinder 4 is rotatably connected to the inside of the threaded cylinder 3 via threads. A disassembly component 7 is provided inside the threaded fixing cylinder 4. The disassembly component 7 includes a threaded rod 701 rotatably connected to the inside of the threaded fixing cylinder 4 via threads. A top rod 702 is fixedly connected to the lower end of the threaded rod 701, and a connecting rod 703 is fixedly connected to the upper end of the threaded rod 701. The handheld frame 1 is easy to grip and improves stability during operation.

[0023] A fixing block 704 is fixedly connected to the upper end face of the connecting rod 703. A rotating rod 705 is slidably inserted inside the fixing block 704. A clamping block 706 is fixedly connected to one end of the rotating rod 705. A flipping block 707 is rotatably connected to one end of the clamping block 706. An extension rod 708 is fixedly connected to one end of the flipping block 707. A support ring 2 is fixedly connected to the lower end of one end of the handheld frame 1. A positioning clamp 6 is fixedly connected to the upper part of the outer wall of the threaded cylinder 3. The extension rod 708 is located inside the positioning clamp 6. The extension rod 708 is taken out from the positioning clamp 6 and adjusted to a horizontal position. It is then inserted into the fixing block 704 in cooperation with the flipping block 707, clamping block 706, etc., to provide a stable force fulcrum for operation and facilitate labor-saving rotation by the operator.

[0024] A rotating frame 5 is fixedly connected to the upper part of the outer wall of the threaded fixing cylinder 4. A positioning groove 8 is opened at the lower end of the threaded fixing cylinder 4. The distance between the support ring 2 and the threaded fixing cylinder 4 can be adjusted by the rotating frame 5 to firmly clamp the chain, prevent the chain from shifting during operation, and ensure the accuracy of the operation. The positioning groove 8 provides guidance for the chain connector to ensure that it accurately enters the inside of the threaded fixing cylinder 4. The threaded rod 701 cooperates with the push rod 702 to accurately transmit force to the chain connector and achieve stable pushing operation. After the operation is completed, the tool can be retracted as a whole, and the extension rod 708 can be reset and fixed in the positioning clamp 6, reducing space occupation, making it easy to carry and store, and avoiding damage or interference caused by the shaking of parts.

[0025] Working principle: When installing the metal chain, remove the extension rod 708 from the positioning clamp 6, rotate the flipping block 707 to bring the flipping block 707, clamping block 706, rotating rod 705, and extension rod 708 to the same horizontal position. Move the extension rod 708 to drive the flipping block 707, clamping block 706, and rotating rod 705 to move synchronously, inserting the flipping block 707 and clamping block 706 into the fixing block 704, making it convenient for the operator to rotate the extension rod 708. Hold the handheld bracket 1 and place the chain to be installed on the support ring 2. Then insert the chain connector into the chain's connecting hole. By rotating the rotating bracket 5 on the outer wall of the threaded fixing cylinder 4, the threaded fixing cylinder 4 moves along the threaded cylinder 3 until the lower end of the threaded fixing cylinder 4 clamps the chain with the support ring 2. At the same time, the chain connector passes through the positioning groove 8 and enters the interior of the threaded fixing cylinder 4.

[0026] By rotating the extension rod 708, the flipping block 707, clamping block 706, rotating rod 705, and fixing block 704 are driven to rotate, which in turn causes the connecting rod 703 to drive the threaded rod 701 to rotate inside the threaded fixing cylinder 4. The push rod 702 at the lower end of the threaded rod 701 moves downward accordingly, pressing against the chain connector and fully inserting the chain connector into the chain, thus completing the installation and fixing of the chain.

[0027] When disassembling a metal chain, position the tool at the part of the chain to be disassembled. Rotate the threaded retaining cylinder 4; the support ring 2 and the threaded retaining cylinder 4 will clamp the chain. Rotate the extension rod 708, causing the threaded rod 701 to move the push rod 702 downwards. The push rod 702 will push the chain connector out of the chain. After the chain connector passes through the support ring 2 and falls off, completing the disassembly, rotate the extension rod 708 and the threaded retaining cylinder 4 in the opposite direction. The threaded retaining cylinder 4 and the push rod 702 will lift up, allowing the worker to remove the chain.

[0028] After the operation is completed, rotate the threaded fixing cylinder 4 and the threaded rod 701 to retract the tool as a whole, reducing the space occupied and making it easier to carry and store. Pull the extension rod 708 to pull the flipping block 707 and the clamping block 706 out of the fixing block 704, and then rotate the extension rod 708 back into the positioning clamp 6 to fix it, preventing the tool parts from shaking.

[0029] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
