Problems solved by technology
[0004] The present invention provides a portable pay-off block, which can effectively solve the above-mentioned background technology that there is no telescopic claw and locking protrusion, which makes it difficult for the user to put the locking protrusion into different through holes to change the length of the telescopic claw. There are no pins and fixing plates, so it is not convenient for users to put the pins into different round holes to change the height of the telescopic claws, and there is no anti-slip sleeve, so the friction between the chute and the cable cannot be increased

The invention discloses a portable paying-off tackle, which comprises telescopic claws, clamping bumps, support rods, pins, fixation plates, a hook, a first support and an antiskid sleeve. The outer portion of a circular hole is sleeved by the corresponding fixation plate. The pins are embedded in the connection places between the fixation plates and the first support. Each support rod is arranged at one end of one fixation plate, and the other end of the support rod is provided with the telescopic claw in an embedded manner. The clamping bumps are arranged on the upper ends of the telescopic claws respectively. A sliding groove is externally sleeved by the antiskid sleeve. The top end of a fixation base is provided with the hook in an embedded manner. The portable paying-off tackle is scientific and reasonable in structure, and safe and convenient to use; through arrangement of the telescopic claws and the clamping bumps, a user can change the length of the telescopic claws conveniently by placing the clamping bumps into different through holes; through the pins and the fixation plates, the user can change the height of the telescopic claws conveniently by placing the pins into different circular holes; and through the antiskid sleeve, friction force between the sliding groove and a cable can be increased.
Description
technical field [0001] The invention relates to the technical field of a pay-off tackle, in particular to a portable pay-off tackle. Background technique [0002] In the process of cable construction, due to the relatively complex working environment and large amount of work, and the contact with the edge of the cable trench during the dragging process of the cable, it is easy to cause damage to the outside of the cable and reduce its service life. The cable slides to ensure the stability and safety of the cable during installation. [0003] The pay-off block currently on the market has a complicated structure, and there are no telescopic claws and locking protrusions. It is not convenient for users to put the locking protrusions into different through holes to change the length of the telescopic claws. There are no latches and fixing plates. It is convenient for the user to put the bolts into different round holes to change the height of the telescopic claws. Without an an...
