[0033] As Figures 1 to 8As shown, the protection box 2 is also provided with guide grooves 2b arranged on the two side walls of the rectangular open groove 2a, the lower clamping block 4 includes a lower V-shaped block 4a and a lower guide block 4b symmetrically arranged on the two sides of the lower V-shaped block 4a, the upper clamping block 5 includes an upper V-shaped block 5a and an upper guide block 5b symmetrically arranged on the two sides of the upper V-shaped block 5a, and the lower guide block 4b and the upper guide block 5b are slidingly fitted in the guide grooves 2b; the design of the guide grooves enables the lower clamping block and the upper clamping block to be slidingly fitted along the guide grooves, and such a structure of the guide grooves can ensure that the clamping device remains stable during movement and avoids deviation or shaking due to external force or vibration, especially for such precision equipment as cable heads, the stable clamping device can effectively prevent the cable heads from being displaced or damaged during transportation; the design of the lower V-shaped block and the upper V-shaped block can better fit the cylindrical or conical surface of the cable head and provide uniform clamping force, such a design not only can adapt to cable heads of different sizes, but also can adapt to cable heads of different shapes, thereby significantly improving the universality of the device, the upper guide block and the lower guide block are symmetrically arranged on the two sides of the lower V-shaped block and the upper V-shaped block and are slidingly fitted with the guide grooves, such a design makes the assembly and disassembly of the clamping device more convenient, and users only need to insert the guide blocks into the guide grooves and slide to complete the installation or adjustment, the guide grooves arranged on the two side walls of the rectangular open groove make the structure of the entire clamping device more compact. Such a design not only saves the space inside the protection box, but also makes the appearance of the protection box more simple; preferably, the guide grooves 2b are dovetail grooves, the design of the dovetail grooves has a unique self-locking feature, which can ensure that the guide blocks will not slide out of the guide grooves during movement due to external force (such as vibration or shaking), such a design significantly improves the stability of the clamping device and prevents the clamping blocks from being displaced during transportation, thereby providing more reliable protection for the cable heads, the shape of the dovetail grooves makes the movement of the guide blocks in the guide grooves more accurate and stable, compared with ordinary groove types, the dovetail grooves can better control the movement trajectory of the guide blocks and avoid deviation or jamming, thereby improving the guiding accuracy of the clamping device, during transportation, the cable heads may be affected by impact, vibration or other external forces, the design of the dovetail grooves can effectively resist these external forces and prevent the guide blocks from being deviated or falling out due to external force, thereby ensuring that the cable heads remain in a stable state.

The protective layer is made of foam pad, which can prevent the cable head from directly contacting the inner wall of the protective box, avoiding scratches or wear on the outer surface of the cable head due to friction or collision, which is particularly important for precision cable heads, which can maintain their appearance integrity and performance stability.

[0035] The outer wall of the protective box 2 is provided with a handle, which allows the user to easily lift and carry the protective box, especially when long-distance transportation or on-site use is required. The handle can significantly improve the convenience of operation, and the design of the handle simplifies the carrying process, allowing the user to complete the carrying task without the aid of other auxiliary tools, thereby improving the operation efficiency.

Compared with electric or hydraulic drive, the handle 6 only needs to be simply welded or bolted, reducing the manufacturing cost.

[0037] As shown in Figure 1 and Figure 2 , the top of the screw rod 7 is fixedly installed with a hand wheel 9, which makes the clamping / loosening operation easier, especially suitable for fastening large or heavy cable heads. Compared with using a wrench or a small knob, the hand wheel 9 is ergonomic, reducing the operator's hand fatigue. The large diameter of the hand wheel 9 allows for smaller amplitude of rotation adjustment, facilitating accurate control of the downward distance of the upper clamping block 5, avoiding damage to the cable head due to over-tightening or loose transportation due to over-loosening. The operator can directly perceive the clamping state through the rotation resistance and number of turns of the hand wheel 9.

[0038] As shown in Figures 1 to 5 , before transportation, first hold the handle 6 with your hand and move the upper clamping block 5 upwards, then rotate the cable head 1 so that the end connector is in a vertical state, then pass through the space between the lower clamping block 4 and the upper clamping block 5 and put it into the protective box 2, so that the cable head 1 is placed close to the cable side in the V-shaped groove 4a of the lower clamping block 4, as shown in Figure 1 and Figure 3After the cable head 1 is shown, the cable head 1 is rotated to be in a horizontal state, then the hand wheel 9 is rotated clockwise, the screw rod 7 moves downward, the upper clamping block 5 is pushed to press downward along the guide groove 2b, the hand wheel 9 is stopped when the cable head 1 does not shake, after clamping, it is checked that the cable head 1 does not shake or deviate, then the cable is transported together with the protection box 2; after being transported to a designated place, first, the hand wheel 9 is counterclockwise rotated, the screw rod 7 rises, the upper clamping block 5 is moved upward by holding the handle 6, and the cable head 1 is taken out from the opening groove 2a after the upper clamping block 5 is completely loosened; the cable head transportation protection structure can adapt to clamping and fixing of cable heads of different sizes and types through an adjustable clamping device, meet the needs of various application scenarios, and improve the safety of cable head transportation; the combination design of the screw rod and the hand wheel makes the operation of the clamping device simple and fast, and facilitates quick installation and disassembly.
