It should be noted that, in the description of the present utility model, terms such as "upper," "lower," "left," "right," "inner," "outer," and the like indicate directions or positional relationships based on the directions or positional relationships shown in the drawings, which are merely for convenience of description, and do not indicate or imply that the apparatus or elements must have a specific orientation, be constructed and operated in a specific orientation, and thus should not be construed as limiting the present utility model.
Furthermore, it should be noted that, in the description of the present utility model, unless explicitly specified and limited otherwise, the terms "mounted," "connected," "provided," and "disposed" are to be construed broadly, and may be, for example, fixedly connected, detachably connected, or integrally connected; can be directly connected or indirectly connected through an intermediate medium, and can be communication between two elements. The specific meaning of the above terms in the present utility model can be understood by those skilled in the art according to the specific circumstances.
Referring to fig. 1 to 5, an embodiment of the present utility model includes:
the utility model provides a can put into bolt of locking position fast, includes bolt 1 and locating lever 2, the inside through-hole 3 that sets up of axial of bolt 1, locating lever 2 detachable installs in bolt 1 through-hole 3, bolt 1 has head hexagonal 11, branching screw rod 12 and connecting axle 13, head hexagonal 11 one end is equipped with connecting axle 13, connecting axle 13 one end is equipped with branching screw rod 12, branching screw rod 12 and connecting axle 13 axis collineation, locating lever 2 has head hexagonal 11 and toper cylinder pole 21, toper cylinder pole 21 one end diameter is greater than the other end diameter, head hexagonal 11 and toper cylinder pole 21 major diameter one end fixed connection;
the bifurcated screw 12 is composed of a plurality of screw blocks 121 which are arranged at equal angles, the screw blocks 121 are in a contracted state when the positioning rod 2 is not inserted, the diameter of the outer end of the bifurcated screw 12 is smaller than that of the inner end of the bifurcated screw 12 at the moment, the screw blocks 121 are in an expanded state when the positioning rod 2 is inserted, and the diameter of the outer end of the bifurcated screw 12 is the same as that of the inner end of the bifurcated screw 12 at the moment;
the diameter of the connecting shaft 13 is smaller than that of the bifurcated screw 12;
