Due to the inertia of the lifting tool, the aluminum coil will rotate when being lifted. To ensure the safety and accuracy of the lifting, it is often necessary to rotate the direction of the C-shaped hook during use to adjust the position of the lifted heavy object. The existing treatment method is that personnel need to push the C-shaped hook or the aluminum coil by hand during the rotation of the C-shaped hook, which is too close to the aluminum coil and the C-shaped hook, and there is no effective safety distance. In case of sudden equipment failure or improper operation and poor coordination, the operator is prone to physical injury due to untimely avoidance, posing a major safety hazard. In view of this problem, the present technical solution is proposed for improvement. Content of the Utility Model

[0014] The following describes the preferred embodiments of the present utility model with reference to the accompanying drawings. Those skilled in the art should understand that these embodiments are only used to explain the technical principle of the present utility model and are not intended to limit the protection scope of the present utility model.
[0015] See Figures 1 to 2 , the embodiments of the present utility model disclose a handheld tool for adjusting a C-shaped hook, mainly including a vertical main rod 1. The main rod 1 can be made of a hollow lever using locally available materials, reducing the overall weight while ensuring the structural strength. A sleeve 2 is slidably installed on the outer side of the main rod 1. At the upper side edges of the main rod 1 and the sleeve 2, a clamping portion is specially designed for clamping the C-shaped hook or the aluminum coil. In order to more effectively clamp the C-shaped hook, a cross bar 101 perpendicular to the main rod 1 is provided at the upper part of the main rod 1 as a part of the clamping portion. At the same time, a clamping rod 201 parallel to the cross bar 101 is provided at the top of the sleeve 2. The two act together to adapt to aluminum coils of different models and C-shaped hooks of different sizes by changing the distance between the cross bar 101 and the clamping rod 201, ensuring the stability of the C-shaped hook and the aluminum coil with respect to the cross bar 101 and the clamping rod 201 during the adjustment process, preventing detachment and reducing sliding, and improving the usage effect.
[0016] In order to ensure that the relative positions of the main rod 1 and the sleeve 2 can remain stable during the adjustment process, a locking device that can be adjusted according to needs is installed at the tail of the sleeve 2. The sleeve 2 can rotate, so that the clamping rod 201 and the cross bar 101 maintain a certain angle, which is convenient for adjustment according to the usage needs and improves the usage effect. A push plate 102 is provided at the top of the main rod 1, and an anti-slip pad is added to the upper surface of the push plate 102. Sometimes it is necessary to push the aluminum coil, and the push plate 102 is used to increase the contact area, and the anti-slip pad prevents slipping to ensure the usage effect.
[0017] The locking device includes a handheld part. When the operator holds the handheld part and applies a certain force, the locking pin 302 inside the handheld part will abut against the main rod 1, thereby fixing the positions of the main rod 1 and the sleeve 2. The handheld part is a handle 3 in the shape of a rectangular frame, which is fixed on the sleeve 2 to ensure the stability of holding. At the same time, a pressing plate 301 is provided on the inner side of the handle 3. The front end of the pressing plate 301 is hinged to the handle 3. When the operator presses down the pressing plate 301, the end of the pressing plate 301 extending into the handle 3 will push the locking pin 302 downward to make it abut against the main rod 1. A rubber pad is cemented at the bottom of the locking pin 302 to increase the friction. A spring 303 is wound around the lower part of the locking pin 302, and the spring 303 pushes the locking pin 302 upward, so that the locking pin 302 automatically disengages and resets when the operator releases the pressing plate 301. An elastic member is installed above the pressing plate 301, so that the pressing plate 301 can ensure that the locking pin 302 is released in the free state, which conforms to the force application habit of people during operation. When the positions of the cross bar 101 and the clamping rod 201 are determined, the pressing plate 301 can be pinched to fix the positions of the sleeve 2 and the main rod 1, ensuring the convenience of people during operation. In addition, in order to facilitate the operator to fix the position of the pressing plate 301 during the operation process, a clamping block 305 is provided at the handheld end of the pressing plate 301, and a lock catch 304 that is clamped with the clamping block 305 is provided on the inner side of the handle 3. After the position is determined, the pressing plate 301 is locked by the lock catch 304, so that the locking rod always acts on the main rod 1. At this time, the operator only needs to control the main rod 1 to better apply the acting force to the C-shaped hook or the aluminum coil, which is convenient for adjusting the position during hoisting. Using the main rod 1 to space the operator a certain distance from the C-shaped hook or the aluminum coil can increase the reaction time for the operator in case of an accident, greatly ensuring the operation safety of the personnel.
[0018] Considering the balance of the tool during use, a counterweight hammer head 103 is installed at the bottom of the main rod 1, so that the center of the main rod 1 is towards the rear, improving the operability. The counterweight hammer head 103 can not only make the tool more stable during operation, but also reduce the labor intensity of the operator to a certain extent, enabling the operator to easily adjust the direction of the C-shaped hook on the premise of maintaining a safe distance, thereby ensuring the safety and accuracy of hoisting and greatly reducing the personal safety risk of the operator.
