Description

Technical Field

[0001] This utility model belongs to the field of automotive repair technology, and more specifically, it relates to a multi-functional steering gear lever wrench. Background Technology

[0002] When repairing a car steering gear, the inner ball joint of the steering stick is subjected to steering force for a long time, and the threads are prone to rusting. It is necessary to use a special steering stick wrench to disassemble and install it. The steering stick wrench uses ring-shaped teeth to engage and fix the ball joint screw, and uses a lever to loosen or tighten it, thus solving the disassembly problem of "difficult to fix the cylindrical surface of the inner ball joint and high torque requirement". Existing steering stick wrenches generally consist of a ring-shaped clamping part, an operating force arm that is hinged to it, and anti-slip teeth set in the two parts.

[0003] Existing application number: CN202320626609.4, this utility model provides a tool for disassembling and assembling the ball joint of a steering gear. The fixing part includes a fixing part and a connecting part. The fixing part is annular with a notch and is integrally formed with the fixing part at the bottom. The locking part is L-shaped and has a square hole through it. One free end of the locking part is rotatably connected to the connecting part. When the locking part is rotated towards the notch of the fixing part, the other free end of the locking part can enter the notch. Using the above technical solution, the notch of the fixing part is aligned with the rudder of the steering gear ball joint, so that the rudder enters the fixing part. Then, the square rod is inserted into the square hole. The locking part is rotated towards the notch of the fixing part, so that one end of the locking part enters the fixing part through the notch and is tightly attached to the rudder. The square rod is manually rotated towards the notch of the fixing part, which can act as a wrench. This application can realize the operation of the rudder of the steering gear ball joint in a limited space, and it is convenient and quick to use, making it suitable for large-scale promotion.

[0004] Based on the above, the steering gear lever wrench relies solely on the anti-slip teeth on the annular clamp and the operating arm to fix the ball end screw. When the inner ball end screw becomes rusted due to long-term stress, the friction of the teeth alone is insufficient for stable engagement, and it is prone to slippage during the application of force, affecting disassembly efficiency or even damaging components. In maintenance environments with insufficient light or limited space, it is difficult to accurately operate the process of inserting the lever into the square hole of the operating arm and the annular clamp engaging the ball end screw, resulting in low disassembly and assembly efficiency. Utility Model Content

[0005] To address the aforementioned technical problems, this utility model provides a multi-functional steering gear stalk wrench. This solves the problem that existing steering gear stalk wrenches rely solely on the annular clamping part and the anti-slip teeth on the operating arm to fix the ball end screw. When the inner ball end screw becomes rusted due to long-term stress, the friction of the teeth alone is insufficient for stable engagement, easily leading to slippage during force application, affecting disassembly efficiency and even damaging components. Furthermore, in maintenance environments with insufficient light or limited space, the insertion of the lever into the square hole of the operating arm and the process of the annular clamping part engaging the ball end screw are difficult to operate precisely, resulting in low disassembly and assembly efficiency.

[0006] The purpose and function of this multi-functional steering gear lever wrench are achieved through the following specific technical means: A multi-functional steering stick wrench includes an annular clamping part, an operating arm, anti-slip teeth, pre-drilled bolt holes, a fixed threaded ring, an anti-slip locking assembly, and an auxiliary guiding assembly. The operating arm is hinged to the left side of the annular clamping part. Two anti-slip teeth are formed, one inside the annular clamping part and the other above the operating arm. Two pre-drilled bolt holes are formed, one on the upper and one on the lower sides of the annular clamping part. The fixed threaded ring has a threaded groove on its outer side, and two fixed threaded rings are provided, fixedly connected to the front and rear sides of the annular clamping part. The anti-slip locking assembly is located on the upper and lower sides of the annular clamping part. The auxiliary guiding assembly is located on the front and rear sides of the annular clamping part and the operating arm.

[0007] Furthermore, the anti-slip locking assembly includes: locking bolts and anti-loosening grooves; two locking bolts are provided, and the two locking bolts are respectively threaded into the two reserved bolt holes; two anti-loosening grooves are provided, and the two anti-loosening grooves are respectively provided inside the two locking bolts.

[0008] Furthermore, the anti-slip locking assembly also includes: a connector and an anti-detachment component; two connectors are provided, and the two connectors are respectively fixedly connected to the upper and lower sides of the annular clamping part; two anti-detachment components are provided, and the right ends of the two anti-detachment components are respectively fixedly connected to the inside of the two connectors, and the left ends of the two anti-detachment components are respectively set inside the two anti-detachment grooves.

[0009] Furthermore, the auxiliary guidance component includes: a first horn component; the first horn component is a square horn-shaped structure that gradually expands outward, and two first horn components are provided, with the two first horn components respectively fixedly connected to the front and rear sides of the operating force arm, and the two first horn components respectively corresponding to the positions of the square operating holes inside the operating force arm.

[0010] Furthermore, the auxiliary guiding component also includes: a second horn member; the second horn member is a circular horn-shaped structure that gradually expands outward, and two second horn members are provided, with the two second horn members respectively threadedly connected to the outside of two fixed threaded rings, and the positions of the two second horn members respectively corresponding to the clamping holes inside the annular clamping part.

[0011] Furthermore, the auxiliary guidance component also includes: a lighting strip; two lighting strips are provided, and the two lighting strips are respectively fixedly connected inside the two second speaker components.

[0012] Compared with the prior art, the present invention has the following beneficial effects: First, by rotating the locking bolt, the friction between it and the ball joint screw of the steering gear stalk is increased. Combined with the original anti-slip teeth, the fixing effect is enhanced, preventing slippage during disassembly and assembly. At the same time, the anti-detachment component restricts the locking bolt, preventing it from completely detaching from the reserved bolt hole and being lost, thus improving the stability and reliability of the tool.

[0013] Secondly, the first horn-shaped component guides the bent rod or the force-adding rod to be inserted into the square hole of the operating force-applying arm, and the second horn-shaped component, together with the lighting strip, assists the annular clamping part in accurately engaging the ball head screw, which is especially suitable for use in environments with poor lighting or limited space, thus improving the ease of operation.

[0014] This invention can better adapt to complex working conditions such as rusted ball joints in steering gear stalks, reduce component damage and disassembly difficulties caused by unstable clamping of the ball joint due to anti-slip teeth, and the design of the auxiliary guide component facilitates use in confined spaces, further enhancing practicality and accelerating the operation efficiency of automotive steering gear maintenance.

[0025] The specific usage and function of this embodiment are as follows: First, the annular clamping part 1 is fitted onto the outside of the ball joint screw of the steering gear spool. Then, the bent rod or extension rod is inserted into the square operating hole inside the operating arm 2. If slippage occurs during operation of the bent rod or extension rod, a wrench is used to rotate the two locking bolts 5, causing the inner ends of the two locking bolts 5 to contact the ball joint screw of the steering gear spool, increasing the friction with the ball joint screw, thus engaging with the original anti-slip teeth 3 to disassemble the ball joint. After disassembly, the two locking bolts 5 are rotated in the opposite direction to loosen the restriction on the ball joint screw. Under the restriction of the left end of the anti-detachment component 601, when the bottom of the locking bolt 5 is disassembled to the middle position inside the reserved bolt hole 4, the top of the locking bolt 5 contacts the crossbar of the anti-detachment component 601, preventing further disassembly of the locking bolt 5 and thus avoiding complete detachment and loss of the locking bolt 5 from the reserved bolt hole 4.
