DETAILED DESCRIPTION

[0020] like Figure 1It is a structural schematic diagram of the utility model, an integrated magnetic rod sleeve, comprising an insert plate 1 and a magnetic rod sleeve 2, the magnetic rod sleeve 2 comprising an integrally formed fixed base plate 3 and 24 groups of sleeves 4, the top of the base plate 3 is provided with two rows of positioning bosses 5, the front end is provided with a plug-in 6, the bottom of the end is provided with a locking block 7 and a handle 8, the surface is provided with 24 groups of neatly arranged through holes 9, the sleeve 4 is integrally connected directly below the through holes 9; the surface of the insert plate 1 is provided with a socket 10 corresponding to the through holes 9, both sides are provided with a slide groove 11 matching the left and right sides of the base plate 3, the inner wall of the front end is provided with a slot 12, and the top of the end is rotatably connected with a buckle 13; the slide groove 11 is provided with a slot 14 corresponding to the positioning boss 5, and the slot 12 corresponds to the plug-in 6 at the front end of the base plate 3; the locking block 7 is arranged in the middle of the bottom of the end of the base plate 3 and corresponds to the buckle 13, and a group of handles 8 are symmetrically provided on both sides.

[0021] According to another embodiment of the utility model, the sleeves 4 are arranged in 4 columns and 6 rows, and reinforcing ribs are provided between every two adjacent groups of sleeves 4 to prevent damage during operation.

[0022] According to another embodiment of the utility model, the wall thickness of each group of sleeves 4 is 0.6±0.05 mm, the length from the bottom of the tube to the tube mouth is 45.5 mm, and the distance between the centers of two adjacent groups of sleeves 4 is 18±0.05 mm.

[0023] According to another embodiment of the utility model, the handle 8 is a cylinder with anti-slip threads on the surface, which is convenient for taking the magnetic rod sleeve 2.

[0024] According to another embodiment of the utility model, the slide groove 11 is a U-shaped guide groove structure, and a plurality of groups of card grooves 14 are provided at the top of the inner wall. The card grooves 14 cooperate with the positioning bosses 5 to make the plug board 1 and the magnetic rod sleeve 2 more closely connected and increase the contact points, wherein the magnetic rod sleeve 2 is injection molded, and the positioning bosses 5 have a certain elasticity and can slide between the slide grooves 11 and slide into the card grooves 14 to clamp.
