The fixed seat 4 is provided with a first connecting hole 42, the connecting block 5 is provided with a second connecting hole 51. The connecting pin 3 is inserted into the first connecting hole 42 and passes through the second connecting hole 51. A locking structure is arranged at the lower end of the connecting pin 3 near the bottom. By arranging the locking structure on the connecting pin 3, the connecting pin 3 is locked and fixed to prevent it from loosening or popping out, thereby improving the stability after connection.

[0035] Please refer specifically to Figures 1 to 7, the locking structure includes two lock blocks 31 oppositely arranged on both sides of the connecting pin 3. The inside of the connecting pin 3 is symmetrically provided with lock grooves 32. The lock blocks 31 are movably connected to the lock grooves 32. A first spring 33 is installed inside the lock grooves 32. Both ends of the first spring 33 are fixedly connected to the lock blocks 31 and the inner wall of the lock grooves 32 respectively. By squeezing the first spring 33, the lock blocks 31 are driven to slide into the lock grooves 32. When the connecting pin 3 is inserted, the elastic force of the first spring 33 drives the lock blocks 31 to reset, thereby fixing the connecting pin 3. A pull ring 6 is installed at the upper end of the connecting pin 3. One end of the lock block 31 away from the first spring 33 is spherical. It is convenient to pull up the connecting pin 3 through the pull ring 6, facilitating the removal of the connecting pin 3 from the first connection hole 42. The spherical structure facilitates the inward extrusion of the lock blocks 31 by the inner walls of the first connection hole 42 and the second connection hole 51 when inserting the connecting pin 3, thereby driving the lock blocks 31 to slide into the lock grooves 32.

[0036] Please refer to Figures 1 to 7 , symmetrically arranged mounting holes 52 are provided near the center on both end faces of the connecting block 5. A positioning block 53 and a second spring 54 are arranged inside the mounting holes 52.

Symmetrically arranged positioning holes 43 are provided near the center on both end faces of the fixed seat 4. One end of the positioning block 53 away from the second spring 54 extends outside the mounting holes 52 and is movably connected to the positioning holes 43. The elastic force of the second spring 54 drives the positioning block 53 to be connected to the positioning holes 43, thereby facilitating the fixation after the connecting block 5 is inserted into the connecting groove 41. The cross-sectional shape of the end of the positioning block 53 fixedly connected to the second spring 54 is T-shaped. Limiting blocks 55 are symmetrically and fixedly arranged on the inner wall of the mounting holes 52. The T-shaped structure cooperates with the limiting blocks 55 to limit the positioning block 53 to prevent it from separating from the mounting holes 52.

[0037] Please refer to Figures 1 to 7 , a pressing rod 7 is arranged inside the positioning holes 43. One end of the pressing rod 7 contacts the positioning block 53, and the other end of the pressing rod 7 extends outside the positioning holes 43 and is fixed with a pressing plate 71. By pressing the pressing plate 71, the pressing rod 7 is driven to contact the positioning block 53, thereby driving the positioning block 53 to slide into the mounting holes 52, separating it from the positioning holes 43, and facilitating the removal of the connecting block 5 from the connecting groove 41. A third spring 72 is sleeved on the outer surface of the pressing rod 7. A clamping seat 73 is fixedly arranged on the outer surface of the end of the pressing rod 7 that contacts the positioning block 53. Clamping blocks 74 are symmetrically and fixedly arranged on the inner wall of the positioning holes 43. Both ends of the third spring 72 are fixedly connected to the clamping seat 73 and the clamping blocks 74 respectively. The elastic force of the third spring 72 facilitates the reset of the pressing rod 7 after pressing the pressing rod 7.

[0038] The implementation principle of a new combined guide block of the utility model is as follows:

[0039] When it is necessary to combine the guide fixed block 1 and the guide movable block 2, the connecting block 5 is inserted into the connecting groove 41 in alignment. The inner wall of the connecting groove 41 drives the positioning block 53 to slide into the mounting hole 52, thereby driving the second spring 54 to compress. When the connecting block 5 is completely inserted, the elastic force of the second spring 54 drives the positioning block 53 to reset, and then drives the positioning block 53 to be connected with the positioning hole 43 to fix the connecting block 5. Then, the connecting pin 3 is inserted into the first connecting hole 42 in alignment. The connecting pin 3 passes through the fixed seat 4 and is connected to the second connecting hole 51 on the connecting block 5. The inner walls of the first connecting hole 42 and the second connecting hole 51 drive the locking block 31 to slide into the locking groove 32. While the locking block 31 slides, it drives the first spring 33 to compress. When the bottom of the connecting pin 3 completely passes through the bottom of the fixed seat 4, the elastic force of the first spring 33 drives the locking block 31 to reset, thus completing the fixed connection between the guide fixed block 1 and the guide movable block 2.

[0040] The above has made an exemplary description of the present utility model in conjunction with the accompanying drawings. Obviously, the specific implementation of the present utility model is not limited by the above methods. As long as such non-substantial improvements are made by adopting the method concept and technical solution of the present utility model, or the concept and technical solution of the present utility model are directly applied to other occasions without improvement, they are all within the protection scope of the present utility model.
