DETAILED DESCRIPTION

[0026] The technical scheme in the utility model embodiment will be clearly and completely described below with reference to the drawings in the utility model embodiment.

[0027] Please refer to Figures 2-6 ;

[0028] The utility model discloses a split type clamp solves the problem of combination alignment under the premise of not affecting the material removal, prolongs the service life, and specifically includes the body 1, one end of the body 1 is connecting portion 2, the other end is winding part 3, the clamp can not be used alone, and the connecting portion 2 is used for being connected with external equipment during winding, and the winding part 3 is provided with detachable end cover 4 at the side edge end face, and the axial position of winding part 3 is provided with gap 31, at least winding part 3 is divided into two parts, and at least one part can be close to the other part, the gap 31 in the embodiment starts from winding part 3, and only one end extends to the end face of winding part 3, a plurality of gaps 31 divide winding part 3 into a plurality of parts to form a claw shape, and the claw shape is closed after external force is applied, and can be restored to the original state after the external force is removed, in addition, as long as the radial length of winding part 3 is reduced during material removal, the coil can be easily removed, therefore, one gap 31 is preferably arranged, of course, a plurality of parts are excluded from the separated state, but the spring reset member is arranged on the support of the parts, and the spring reset member is restored after the parts are closed, and the spring reset member is closed after external force is applied, and can be restored to the original state after the external force is removed, no matter which way is used, the same technical effect can be achieved.

[0029] In order to avoid the folding caused by the external force applied to the winding part 3 during winding, the gap 31 extends to the end surface of the winding part 3 and forms a clamping groove 32. During operation, the end cover 4 is installed at the end of the winding part 3, and the end cover 4 is provided with a limiting block 41 matched with the clamping groove 32 near the end surface of the winding part 3. Before winding, a paper sheet is wound on the winding part 3, and of course, it can be different according to the actual situation, which is not limited here. In addition, the end cover 4 is used to limit the distance and shape of the coil during winding. Since the two parts of the winding part 3 are limited from closing by the limiting block 41, the inner diameter of the coil wound on the winding part 3 is the same as the outer diameter of the winding part 3 in the initial state, which also meets the standard of forming a coil. After completing the winding of the coil, the end cover 4 is separated from the winding part 3. Preferably, the end surface of the end cover 4 away from the winding part 3 is provided with an external hanging part 42 for clamping and fixing with an external device. The end cover 4 does not limit the coil, and then the coil can be transversely separated from the winding part 3. Since the coil is tightly wound on the winding part 3, and the two parts are separated from the clamping groove 32, the radial distance of the two parts of the winding part 3 is reduced during the transverse separation process, so that the coil can be smoothly separated. After the coil is completely separated, the two parts of the winding part 3 are separated again, the end cover 4 is fixed on the end surface of the winding part 3 again, and the gap 31 is limited at the same time, and the next winding process is entered.

[0030] In the above process, the winding part 3 maintains the same radial distance under the limitation of the limiting block during winding, and the gap 31 can reduce the radial distance of the winding part 3 during material separation, making the material separation more simple. The utility model integrates the combination of the two components into one component, removes the traditional inclined surface 62 alignment structure, makes the material separation process more simple and convenient, and makes the end cover 4 more quickly installed on the winding part 3 again. If the end cover 4 or the winding part 3 is damaged, the parts can be replaced individually, and the other part can continue to be used.
