Detailed Description
In order to better understand the technical content of the invention, specific embodiments are provided below, and the invention is further described with reference to the accompanying drawings.
Referring to fig. 1 to 5, the invention provides a wrench with a quick adjustment function, which comprises a handle 1, a fixed clamp 2 and a movable clamp 3, wherein the fixed clamp 2 is fixedly arranged at the front end of the handle 1, a sliding groove 4 is arranged at the front end of the handle 1, a sliding rail 5 is arranged in the sliding groove 4, a sliding block 6 is slidably sleeved on the sliding rail 5, the movable clamp 3 is fixedly connected with the top of the sliding block 6, two parallel guide rods 7 are arranged in the sliding groove 4, a locking strip 8 is sleeved on each guide rod 7, the locking strip 8 is arranged in parallel with the sliding block 6, a first rack 9 is arranged at the rear end of the sliding block 6, a second rack 10 is arranged at the front end of the locking strip 8, the first rack 9 and the second rack 10 are mutually meshed, a spring 11 is arranged on each guide rod 7, and the rear end of the locking strip 8 is connected with the sliding groove 4 through the spring 11, the surface of the handle 1 is provided with a reset component.
When the nut assembling and disassembling tool is used, the index finger can be pressed on the outer side of the fixed clamp 2 to enable the inner side of the fixed clamp 2 to be abutted against one side of a nut to be assembled and disassembled, the outer side of the movable clamp 3 is pushed by a thumb, the movable clamp 3 slides upwards along the sliding rail 5 through the sliding block 6, the oblique tooth edge of the first rack 9 is abutted against the oblique tooth edge of the second rack 10, when the first rack 9 slides upwards, the oblique tooth edge of the first rack 9 applies a component force towards the right direction to the oblique tooth edge of the second rack 10 to push the locking strip 8 to slide towards the right direction along the guide rod 7, the sliding block 6 can drive the movable clamp 3 to slide upwards to rapidly drive the movable clamp 3 to be abutted against the other side of the nut to be assembled and disassembled, the locking strip 8 always keeps the abutment of the second rack 10 and the first rack 9 under the action of the spring 11, at the moment, if the movable clamp 3 is subjected to a downward force, the right-angle edge of the first rack 9 is abutted against the right-angle edge of, and locking strip 8 can't move down under the effect of guide bar 7, and second rack 10 prevents first rack 9 and slides down, accomplishes the locking effect to activity pincers 3, can drive fixed pincers 2 and activity pincers 3 through pulling handle 1 and carry out the dismouting to the screw. After the disassembly and assembly are completed, the wrench is taken down, and the movable pliers 3 can be driven to slide downwards through the reset component to reset so as to prepare for the next operation. This device is in narrow, be difficult to through the operation area of two-handed operation, and the accessible one hand realizes the position of the gripping of handle 1 and regulation activity pincers 3, convenient and fast. In the insufficient region in field of vision, also can realize fast through the one hand that fixed pincers 2 and activity pincers 3 press from both sides tight function to the nut, improve the tight precision of clamp to the nut, improve dismouting efficiency. When the lubricating performance of the parts in the sliding groove 4 needs to be kept, lubricating oil can be filled into the parts, the movable pliers 3 are not stained with oil, and the possibility that the oil stains hands when the wrench is used can be greatly reduced.
The reset assembly comprises a toggle groove 12 and a toggle piece 13, the toggle groove 12 is formed in the surface of the handle 1, the toggle groove 12 is communicated with the sliding groove 4, and the toggle piece 13 penetrates through the toggle groove 12 and the locking strip 8 and is fixedly connected with the locking strip. When needing to restore to the throne with the lapse of activity pincers 3 lapse, stir the plectrum 13 on handle 1 surface right, drive locking strip 8 and remove right along guide bar 7, second rack 10 loses the butt effect with first rack 9, can easily promote the lapse of activity pincers 3 this moment and restore to the throne.
The first rack 9 and the second rack 10 are made of alloy materials, so that the biting force and the strength of the first rack 9 and the second rack 10 are improved, and the abrasion degree of the first rack 9 and the second rack 10 is reduced.
The teeth of the first rack 9 and the second rack 10 are arc-shaped teeth, and when the first rack 9 slides upwards, the arc-shaped edges of the arc-shaped teeth can better push the second rack 10 to slide rightwards, so that the sliding effect of the movable clamp 3 is improved.
