Description

Technical Field

[0001] This utility model relates to the technical field of electric wrench clamps, and in particular to an electric wrench clamp for use in narrow spaces. Background Technology

[0002] When tightening nuts in modern, typically confined workspaces, operators often cannot directly use efficient tools like electric wrenches due to strict space constraints. While electric wrenches can significantly improve work efficiency, their size and operational requirements make them difficult to use in confined spaces. Even when using more flexible ratchet wrenches, the operation still relies on repeated manual rotation and adjustment, which not only consumes a lot of time and energy but also inevitably leads to a significant reduction in overall work efficiency. Frequent manual operation can easily cause operator fatigue and may also affect the tightening quality of nuts due to uneven force, further increasing the difficulty and complexity of the operation. Utility Model Content

[0003] To solve the above-mentioned technical problems, this utility model provides an electric wrench clamp for use in narrow spaces, which optimizes the force transmission path and extends the operating length of the electric wrench, enabling the operator to complete the tightening of nuts in a shorter time, greatly reducing the operation time and improving production efficiency.

[0004] This utility model discloses an electric wrench clamp for use in confined spaces, comprising a clamping part, a nut part, and an electric wrench head part. The nut part is mounted on the clamping part, and the electric wrench head part is mounted on the clamping part and connected to the input end of the nut part. The clamping part is used to firmly fix the nut, ensuring that it will not shift during tightening. Through the ingenious extension of the mechanical structure, the electric wrench can be attached to the electric wrench head part, increasing the length of the electric wrench to extend beyond the confined working space. This allows the operator to directly control the electric wrench from outside the confined space, optimizing the overall workflow and making each step smoother and more efficient, bringing significant economic benefits and time savings to enterprises and operators.

[0005] Preferably, the clamping components include multiple bolts, a lower clamping plate, multiple fixing nuts, a support block, and an upper clamping plate. The support block is located between the lower clamping plate and the upper clamping plate. Multiple connecting holes are provided on the lower clamping plate, the support block, and the upper clamping plate. Multiple bolts are inserted into the connecting holes, and fixing nuts are screwed onto the bolts. The lower clamping plate, the support block, and the upper clamping plate are provided with hollow grooves. When in use, the operator holds one end of the lower clamping plate and the upper clamping plate. The force transmission path is optimized and the operating length is extended. Through the ingenious extension of the mechanical structure, the nuts can be firmly fixed to ensure that no displacement occurs during the tightening process.

[0006] Preferably, the nut portion includes gear 1, gear 2, gear 3, and a positioning pin. The positioning pin is installed between the lower plate and the upper plate of the fixture. Gear 2 is installed on the outer wall of the positioning pin. Gear 1 rotates between the lower plate and the upper plate of the fixture below gear 2, and gears 1 and 2 mesh. Gear 3 is located between the lower plate and the upper plate of the fixture above gear 2. The nut placement area is in the middle of gear 3. Gear 3 is precisely aligned with the center hole on the upper plate of the fixture that mates with the nut. The nut to be tightened is securely inserted into the specific gear 3. The positioning pin provides positioning and support. Gear 1 drives gear 2 to rotate, and gear 2 drives gear 3 to rotate, transmitting power to tighten the nut. Through the simple nut placement area, different sized nuts can be accommodated, greatly improving the tool's versatility and flexibility.

[0007] Preferably, the electric wrench head includes a torque wrench head portion, which is coaxially connected to gear No. 1; the torque wrench head portion is connected to the electric wrench body to transmit power.

[0008] Preferably, the lower plate and upper plate of the clamp are made of high-strength alloy material; the high-strength alloy material ensures the stability and durability of the clamp under long-term high-intensity use, and can maintain good performance even in frequent tightening operations, reducing tool wear and replacement frequency.

[0009] Compared with the prior art, the beneficial effects of this utility model are as follows: through the ingenious extension of the mechanical structure, the electric wrench can be attached to the end of the electric wrench, thereby increasing the length of the electric wrench to extend beyond the confined working space. The operator can then directly control the electric wrench to perform operations from outside the confined space, optimizing the overall workflow and making each link smoother and more efficient, bringing significant economic benefits and time savings to enterprises and operators.
