[0023] Refer to the instruction manual Figure 1-5The utility model provides a hydraulic cylinder guide sleeve connection structure, comprising a hydraulic cylinder body 1, a guide sleeve body 2 is sleeved on the top of the hydraulic cylinder body 1, and two sets of mounting components for connection and fixing are arranged between the guide sleeve body 2 and the hydraulic cylinder body 1;

[0024] like Figure 2-5 As shown, each group of mounting components includes a connected transverse groove 3 and a vertical groove 4, wherein the transverse groove 3 is arranged on one side of the top end of the vertical groove 4, and the transverse groove 3 and the vertical groove 4 are both opened inside the bottom end of the guide sleeve body 2, and a pressing block 5 is arranged inside the transverse groove 3, and the end of the pressing block 5 away from the vertical groove 4 passes through the transverse groove 3 and extends to the outside of the guide sleeve body 2; a positioning block 6 is arranged inside the vertical groove 4, and the positioning block 6 is arranged in an L shape, and the side of the top of the positioning block 6 close to the transverse groove 3 is arranged as an inclined surface, and the bottom end of the positioning block 6 passes through the vertical groove 4 and extends to the inside of the hydraulic cylinder body 1, and a positioning column 7 is arranged at the bottom end of the positioning block 6, and the bottom end of the positioning block 6 is sleeved on the outside of the positioning column 7, and a spring 8 is arranged on the side of the bottom end of the positioning block 6 away from the transverse groove 3, and the spring 8 is sleeved on the outside of the positioning column 7.

[0025] like Figure 3 and 5 As shown, the inner wall of one side of the bottom end of the vertical groove 4 close to the top inclined surface of the positioning block 6 is processed into an inclined surface, and the inclination direction of the inclined surface at the bottom end of the vertical groove 4 is consistent with the inclination direction of the top inclined surface of the positioning block 6. By setting one side of the bottom end of the vertical groove 4 as an inclined surface, when the positioning block 6 contacts the vertical groove 4, the vertical groove 4 limits the positioning block 6 so that the positioning block 6 is pushed inward.

[0026] like Figure 3 and 5 As shown, a slide groove 9 is provided at the top and the bottom of the inner cavity of the transverse groove 3, and a slider 10 is provided inside the end of the slide groove 9 away from the vertical groove 4. The end of the slider 10 away from the slide groove 9 is fixed to the pressing block 5. Through the cooperation of the slider 10 and the slide groove 9, the displacement of the pressing block 5 can be limited to avoid separation of the pressing block 5 from the guide sleeve body 2, thereby ensuring the stability of the pressing block 5 during movement.

[0027] like Figure 3 As shown, a mounting groove 11 is provided on one side of the hydraulic cylinder body 1 close to the positioning column 7, and the bottom ends of the positioning column 7, the spring 8 and the positioning block 6 are all arranged inside the mounting groove 11.
