Compared with the prior art, the utility model discloses a nylon rope grabber's beneficial effect as follows:

(1) adopt two hook portions to replace unilateral hook structure for the difficult unhook of nylon rope, labour saving and time saving.

(2) Two arms of the grapple are crossed to form a ring part with variable size and an eight-shaped part with variable angle, so that the two hook parts can be operated more easily when grabbing the nylon rope, the nylon rope can be grabbed simply, and the nylon rope is not easy to unhook.

(3) And the limiting ring is adopted to ensure that the two crossed arms are smoothly opened and closed.

(4) And the limiting part is adopted to prevent the slide bar from falling out of the guide groove.

(5) The plastic material is adopted, the material is convenient to obtain, the cost is low, the metal material is adopted, and the service life is long.

The invention will become more apparent from the following description when taken in conjunction with the accompanying drawings which illustrate embodiments of the invention.

Detailed Description

Embodiments of the present invention will now be described with reference to the drawings, wherein like element numerals represent like elements throughout.

Referring to fig. 1-5, the nylon rope grabber comprises a handle 1, a first shell 2, a second shell 3, a traction piece 4 and a grabbing hook 5. The handle 1 is sleeved with a sliding operating handle 6. The near ends of the first shell 2 and the second shell 3 are fixedly connected with the far end of the handle 1. The second shell 3 is sleeved in the first shell 2. The traction piece 4 is sleeved in the second shell 3. The far end of the traction piece 4 is fixedly connected with the grapple 5, and the near end of the traction piece 4 is fixedly connected with the sliding operation handle 6.

Specifically, the proximal ends of the first and

second housings

2 and 3 are integrally connected to the distal end of the handle 1. The first shell 2, the handle 1 and the sliding operation handle 6 are made of plastic materials, and the second shell 3, the traction piece 4 and the grapple 5 are made of metal materials.

Two opposite side walls at the far end of the second outer shell 3 are respectively provided with a guide groove 31 distributed along the far and near directions.

The grapple 5 comprises two arms 51 and two hooks 52. The two arms 51 intersect to form a proximally located variably sized loop 511 and a distally located variably angled octant 512. The distal end of the pulling member 4 is fixedly connected to the ring portion 511. The two distal ends of the splayed portion 512 are bent toward each other to form the two hook portions 52. The two arm parts 51 are sleeved with a limiting ring 53 at the crossing position, and the limiting ring 53 is made of metal.
