[0029] The extendable and adjustable protective device connects multiple sets of outer tubes 2 through the riser 501 and hollow rod 502 to enhance structural strength. Openings are provided at the front of the riser 501 and the rear of the hollow rod 502 for sliding of the needle plate 507.

[0030] exist Figure 5 In the hollow rod 502, a T-shaped tube 503 slides through the upper part of the inner wall. An inner rod 504 is slidably connected inside the T-shaped tube 503. The inner rod 504 is bolted to the lower part of the inner wall of the riser 501. A spring 505 is sleeved on the outer side of the inner rod 504. The spring 505 is screwed to the lower part of the T-shaped tube 503 and the lower part of the inner wall of the hollow rod 502.

[0031] The extendable and adjustable protective device has a T-shaped tube 503 that slides along the inner rod 504. A spring 505 pushes the T-shaped tube 503 upward, causing multiple sets of needle plates 507 to move upward along with the T-shaped tube 503.

[0032] exist Figure 2 and Figure 5 In the middle, the bottom of the inner tube 3 is provided with a locking hole 506.

When the two sets of protective devices are spliced, the respective cantilever 601 is pushed to rotate. When the two sets of cantilever 601 are close, the magnetic rings 603 in the two sets of cantilever 601 attract each other, aligning the through grooves of the two sets of cantilever 601, which facilitates the insertion of the long screw 604.

[0040] exist Figures 1-4 In the middle, a long screw 604 slides through the cantilever 601 and the magnetic ring 603.

[0041] The extendable and adjustable protective device uses a long screw 604 to pass through two adjacent sets of cantilever 601, limiting the two sets of protective devices together.
