Description

Technical Field

[0001] This utility model relates to the field of clamping and installation tools, and in particular to a spring installation tool. Background Technology

[0002] Currently available tools for installing and removing springs without a hook mechanism rely on brute force, posing significant safety hazards to installers and causing surface damage to the mounting surface and the spring itself. Therefore, developing a labor-saving scissor-type spring installation tool is of great importance. Summary of the Invention

[0003] The purpose of this utility model is to provide a labor-saving scissor-type spring installation tool to overcome the technical problem that existing spring installation and disassembly tools require brute force.

[0004] To achieve the above objectives, this utility model provides the following technical solution:

[0005] This utility model provides a spring installation tool, including a first handle, a second handle, and a threaded rod. The first handle is hinged to a first movable block, and the second handle is hinged to a second movable block. The first and second movable blocks are slidably connected to both ends of the threaded rod. The first and second movable blocks are symmetrically arranged on the threaded rod. The two ends of the threaded rod are respectively provided with threads, and the thread directions at the two ends of the threaded rod are opposite.

[0006] Preferably, the first handle and the second handle are connected by a hinge.

[0007] Preferably, the first movable block and the second movable block are threadedly connected to the positive and negative thread screws, respectively.

[0008] Preferably, the lower ends of the first handle and the second handle are provided with V-shaped hooks.

[0009] Preferably, the sides of the first handle and the second handle are also provided with notches.

[0010] Preferably, a hexagonal screw is fixedly provided at the middle position of the positive and negative thread screw.

[0011] Compared with the prior art, the present invention has the following advantages:

[0012] 1. It is designed with two notches to hook the spring, preventing the spring from detaching from the tool and causing injury to the installer.

[0013] 2. It has two irregular hooks, which mainly play a role in space utilization, providing more installation space.

[0014] 3. It features two movable nuts, one with a positive thread and the other with a negative thread. The retraction function can be easily achieved by rotating the positive and negative thread screws, making this scissor-type hook spring installation tool more labor-saving.

[0018] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0019] Example 1

[0020] Please see the appendix Figure 1 The present invention provides a spring installation tool, comprising a first handle 1, a second handle 2, and a forward and reverse threaded screw 3. The first handle 1 is hinged to a first movable block 5, and the second handle 2 is hinged to a second movable block 6.

[0021] The first movable block 5 and the second movable block 6 are slidably connected to the two ends of the positive and negative thread screw 3, respectively. The first movable block 5 and the second movable block 6 are symmetrically arranged on the positive and negative thread screw 3. The two ends of the positive and negative thread screw 3 are respectively provided with threads, and the thread directions of the two ends of the positive and negative thread screw 3 are opposite.

[0022] The retraction and support function can be easily achieved by rotating the forward and reverse threaded screw 3.

[0023] The first handle 1 and the second handle 2 are connected by a hinge.

[0024] The first movable block 5 and the second movable block 6 are respectively threaded to the positive and negative thread screws 3.

[0025] The lower ends of the first handle 1 and the second handle 2 are provided with V-shaped hooks 8.

[0026] The two V-shaped hooks primarily serve to maximize space, providing more room for installation.

[0027] The sides of the first handle 1 and the second handle 2 are also provided with notches 4.

[0028] The two notches 4 can hook the spring, preventing the spring from detaching from the tool and causing injury to the installer.

[0029] A hexagonal screw body 7 is fixedly positioned in the middle of the screw rod 3 (both positive and negative threads). The hexagonal screw body 7 can be rotated manually, or a wrench can be used to assist in rotating it.

[0030] Working principle and usage: In this embodiment, the spring installation tool works by rotating the screw hexagon 7 in the forward direction, causing the first movable block 5 and the second movable block 6 to slide towards each other at both ends of the screw rod 3; by rotating the screw hexagon 7 in the reverse direction, the first movable block 5 and the second movable block 6 slide in opposite directions at both ends of the screw rod 3, thus achieving the effect of supporting the two movable blocks. This allows for adjustment of the distance between the two notches 4 at the ends of the first handle 1 and the second handle 2. After adjusting the distance between the two notches 4 to match the length of the spring, the spring can be installed.

[0031] This utility model provides a spring installation tool, including a first handle, a second handle, and a threaded screw. Two notches are designed to hook the spring, preventing it from detaching and causing injury to the installer. Two V-shaped hooks are designed to maximize space, providing more room for installation. Two movable nuts, one with a positive thread and one with a negative thread, are designed. The screw can be easily rotated to achieve the spring's support function. This scissor-type hook spring installation tool requires less effort.

[0032] The above description of the disclosed embodiments enables those skilled in the art to make or use the present invention. Various modifications to these embodiments will be readily apparent to those skilled in the art, and the general principles defined herein may be implemented in other embodiments without departing from the spirit or scope of the present invention. Therefore, the present invention is not to be limited to the embodiments shown herein, but is to be accorded the widest scope consistent with the principles and novel features disclosed herein.
