[0002] Leather is the animal skin that has been denatured and is not easily perishable after physical and chemical processing such as hair removal and tanning. Leather is composed of natural protein fibers tightly woven in three-dimensional space. It has a special grain layer on its surface, with natural grain patterns and luster, and a comfortable hand feeling. The leather industry covers the main industries such as leather making, shoe making, leather clothing, leather goods, fur and its products, as well as supporting industries such as leather chemicals, leather hardware, leather machinery, and accessories. Among them, auxiliary locking structures need to be set at the feeding and discharging ends of leather belt processing equipment to prevent the phenomenon of the loose leather belt from winding when entering the equipment. The existing locking structures for leather belt processing generally lock by the principle of using a threaded push to fix the clamping plate to bite the straight-through leather belt. It completely relies on the frictional resistance generated by the threaded push of the clamping plate to form a locking state with the leather belt. Therefore, the stability is not high, and the locking strength for the leather belt is limited. Therefore, in view of the above problems, the present application has invented a locking structure for leather belt processing, which effectively solves the problem of limited locking strength for the leather belt.

Then rotate the threaded adjustment push rod 4. Through the threaded propulsion principle of the threaded adjustment push rod 4 and the locking shell 1, drive the displacement of the inner push cylinder 5 up and down inside the locking shell 1. Utilize the displacement difference generated by the angular push of the inclined support rod 7 to drive the two contact push cylinders 9 at its bottom to push and support outward in the horizontal direction, so as to increase the contact surface with the second resistance protection sleeve 24 on the positioning support cylinder 23, and make use of the design that the leather material belt 2 is bent into multiple S shapes inside the locking shell 1, greatly improving its frictional resistance to increase the tensile strength during locking. Then rotate the end of the adjustment rotary pressing cylinder 28 on the right, so that the adjustment rotary pressing cylinder 28 rotates inside its locking shell 1.
