[0034] Embodiment 2:

[0035] Based on Example 1, please refer to Figure 3 .

[0036] Specifically, a take-out groove 21 is provided at the top of the operating table 1, and the take-out groove 21 is located on the side of the fixed block 2 close to the support frame 20. A material box 22 is connected to the bottom of the operating table 1, and the material box 22 is connected to the take-out groove 21. A pushing plate 23 is slidably connected in the material box 22. Slide grooves 24 are provided on both sides of the material box 22. Slide plates 25 are connected on both sides of the pushing plate 23. The two slide plates 25 are respectively slidably connected in the two slide grooves 24. Two electric push rods 26 are connected to the bottom of the operating table 1. Working grooves 27 are provided on the two slide plates 25. The output ends of the two electric push rods 26 pass through the working grooves 27 and are connected to lifting frames 28. The tops of the two lifting frames 28 are respectively connected to the bottoms of the two slide plates 25. By adopting the above technical solution, by taking out the groove 21 and the material box 22, it is convenient to put in the rubber sleeves for the wiring harness, which is convenient for the staff to take during processing. The electric push rod 26 can drive the push plate 23 in the material box 22 to rise. When the number of rubber sleeves in the material box 22 is reduced, the rubber sleeves in the material box 22 in the push plate can be pushed and raised, thereby facilitating the staff to take them out and reducing the situation where the staff need to bend down and reach into the material box 22 to take the rubber sleeves for use, thereby reducing the workload of the staff.

[0037] The working principle of the utility model is as follows: when in use, the staff puts the rubber sleeve used for the wiring harness into the material box 22, and the rubber sleeve falls on the push plate 23 in the material box 22. The staff takes the rubber sleeve through the taking-out slot 21. When the rubber sleeve in the material box 22 is gradually reduced, the external power supply is used to power the electric push rod 26 to start working. The electric push rod 26 shortens and drives the lifting frame 28 to rise, driving the slide plate 25 to rise on the electric push rod 26, and the two slide plates 25 are raised in the two slide grooves 24, thereby driving the push plate 23 in the material box. The rubber sleeve in the material box 22 is raised, driving the push plate 23 to push and raise the rubber sleeve in the material box 22, and then rising until the rubber sleeve is located in the removal slot 21 of the operating table 1, and the electric push rod 26 stops working, so as to facilitate the staff to perform material taking operation during processing. After the staff takes out the rubber sleeve in the removal slot 21, align one end of the rubber sleeve with the support frame 20, and push the rubber sleeve to slide and sleeve on the support frame 20, and the hydraulic push rod 6 works, the hydraulic push rod 6 shortens, drives the fixed seat 7 to be lowered, and drives the first push frame 8 and the first support rod on the top of the fixed seat 7 9 and the second support rod 10 are lowered, the first push frame 8 directly drives the first sector block 15 to descend, and the second push frame 11 is driven to descend in the second limiting groove 4 through the first support rod 9, and the second push frame 11 is limited by the two first limiting wheels 13 in the second limiting groove 4, so that the second push frame 11 rotates to the side away from the first push frame 8 while descending, and the third push frame 12 is driven to descend in another second limiting groove 4 through the second support rod 10, and the third push frame 12 is limited by the two second limiting wheels 14 in the second limiting groove 4. The third push frame 12 is limited so that it rotates to the side away from the first push frame 8 while descending, and the first sector block 15 is driven to descend by the first push frame 8, and the second sector block 16 is driven to move obliquely downward to one side by the second push frame 11, and the third sector block 17 is driven to move obliquely downward to the other side by the third push frame 12, so that the first sector block 15, the second sector block 16, the third sector block 17 and the fourth sector block 19 are separated, thereby driving the expansion frame 20 on one side to separate, and the rubber sleeve sleeved on the expansion frame 20 is expanded;

[0038] After expansion, the staff inserts the wire harness between the four expansion frames 20, within the space where the rubber sleeve is expanded. After insertion, the staff removes the rubber sleeve from the expansion frame 20 by gripping the rubber sleeve. The special shape of the expansion frame 20 facilitates the removal of the rubber sleeve. When removing, by pulling the wire harness, when the rubber sleeve is completely removed from the expansion frame 20, the rubber sleeve is covered and sleeved on the wire harness, thus completing the processing operation. After completion, the hydraulic push rod 6 works, the hydraulic push rod 6 extends, and through the fixed seat 7, the first push frame 8 is driven to rise. Through the first support rod 9 and the second support rod 10, the second push frame 11 and the third push frame 12 are pushed to rise, thereby driving the first sector block 15, the second sector block 16 and the third sector block 17 to approach the fourth sector block 19. Through contact, the first sector block 15, the second sector block 16, the third sector block 17 and the fourth sector block 19 are combined into a complete disc. At this time, the expansion frames 20 on one side form a complete cone, thus facilitating the sleeving of a new rubber sleeve for processing operations.

[0039] This specific embodiment is only an explanation of the present invention, and it is not a limitation of the present invention. Those skilled in the art can make modifications to this embodiment without creative contributions according to needs after reading this specification, but as long as it is within the scope of the claims of the present invention, it is protected by the patent law.
