When the flexible protection device 4 in this embodiment is used, run through flexible protection device 4 with the one end of electric wire 3, make flexible protection device 4 cover establish on electric wire 3, the position of protective sheath 221 is fixed the back, with one end of spring 42 and one side contact of tip go-between 223, and laminate one side of spring baffle 41 and one end of spring 42, swivel collar 45 makes screwed pipe 43 and the laminating of the lateral wall of electric wire 3, the position of fixed spring 42, make electric wire 3 when crooked, carry out flexible protection to electric wire 3, avoid electric wire 3 to carry out wide-angle's buckling, guarantee electric wire 3's normal use.

Example 3

For the convenience of the middle connection ring 222 and the end connection ring 223 to be convenient for storage and transportation, referring to fig. 14, one end of the end connection ring 223 is disposed inside the middle connection ring 222, one side of the end connection ring 223 is attached to the middle connection ring 222 on the outermost side, the end connection ring 223 is disposed inside the middle connection ring 222, and the middle connection rings 222 are sleeved with each other, so that the occupied space for placing the middle connection ring 222 and the end connection ring 223 is reduced, and the middle connection ring 222 and the end connection ring 223 are convenient to carry.

The second objective of the present invention is to provide a method for using a sliding type long wire-protecting type plug inner frame, which includes any one of the above-mentioned inner frames, and includes the following steps:

s1, one end of the electric wire 3 penetrates the flexible protection device 4, so that the flexible protection device 4 is sleeved on the electric wire 3, one end of the electric wire 3 penetrates the placing cavity 214 and the connecting clamping block 212 and is inserted into the plug connecting frame 1 for circuit connection, after the circuit is connected, the two pressing covers 11 are respectively clamped at one side of the connecting frame 21, so that the connecting clamping block 212 enters the clamping groove 12, the inserting plate 218 is inserted into the inserting groove 14, and the two pressing covers 11 are connected together by using screws, so that the plug connecting frame 1 is stably installed at one side of the wire body protection frame 2, and at the same time, the connecting clamping plate 23 is pushed, so that one end of the connecting clamping plate 23 slides into the clamping groove 13, the side limiting sliding plate 231 slides in the side limiting sliding groove 216, so as to limit the position of the wire body protection frame 2 at one side of the plug connecting frame 1, and ensure the installation stability of the wire body protection frame 2;

s2, adjust the position of the protection sleeve 221 according to the length of the wire 3 to be protected, when adjusting the position of the protection sleeve 221, turn over and pull the protection sleeve 221 to turn over the protection sleeve 221 inside the placement cavity 214, the outer sleeve 2213 drives the middle sleeve 2212 and the inner sleeve 2211 to rotate around the connecting hinge rod 2217, the inner slider 2216 slides inside the inner chute 213, when the inner sleeve 2211 and the side wall of the wire 3 are attached, one end of the inner sleeve 2211 is pulled to move the inner sleeve 2211 along the direction of the wire 3, the moving inner sleeve 2211 drives the connecting slider 2215 to slide in the outer chute 2214 and drives the middle sleeve 2212 to move along with the movement of the inner sleeve 2211, when the inner sleeve 2211 moves to a proper position, the two inner sleeve 2211 are fixed and clamped on the wire 3 by rotating the end connecting ring 223 and the middle connecting ring 222, and the middle sleeve 2212 and 2213 are fixed on the inner sleeve 2211 respectively, The middle sheathing 2212, so that the sheathing 221 protects the electric wire 3;

s3, after the position of the protection sleeve 221 is fixed, one end of the spring 42 is contacted with one side of the end connection ring 223, one side of the spring baffle plate 41 is jointed with one end of the spring 42, the positioning ring 45 is rotated to joint the threaded pipe 43 with the side wall of the electric wire 3, the position of the spring 42 is fixed, when the electric wire 3 is bent, the electric wire 3 is flexibly protected, after the position of the flexible protection device 4 is installed, one end of the connection bar 242 is inserted into the connection groove 217, one side of the outer sleeve plate 2213 is arranged in the placement groove 241, and one side of the connection frame 21 is protected by the baffle plate 24.

The foregoing shows and describes the general principles, essential features, and advantages of the invention. It will be understood by those skilled in the art that the present invention is not limited to the embodiments described above, and the preferred embodiments of the present invention are described in the above embodiments and the description, and are not intended to limit the present invention.
