For achieving the above object, technological scheme of the present invention is as follows:
A kind of rack connects protective gear, it is characterized in that: comprise link and guard member, described link comprises head and joint, described head is circular, the upper plane of head is provided with polygonal grooves, described joint side is provided with at least two symmetrical arc casting lug thereons, described guard member comprises binding block and withdrawing device, described binding block Lower Half is arranged in groove, sealing layer is provided with outside binding block Lower Half, the lower plane of binding block Lower Half is provided with symmetrical blind hole, the first half of binding block is circular, described withdrawing device comprises press rods, pressure plate, spring, described pressure plate is arranged between the lower plane of bottom portion of groove and binding block Lower Half, pressure plate is provided with through hole, the position of described through hole is corresponding with blind hole, described press rods is connected with pressure plate through binding block, described spring is arranged on below pressure plate.
As a modification of the present invention, described groove is corner or hexagonal groove.
As a modification of the present invention, described sealing layer is rubber layer.
As a modification of the present invention, the Lower Half of described binding block is tapered, up big and down small.
As a modification of the present invention, the quantity of described blind hole is 2.
As a modification of the present invention, described press rods exceeds binding block 2-4mm.
As a modification of the present invention, the top of described press rods is provided with protecting sheet.
The invention has the beneficial effects as follows:
