Detailed Description

Embodiments of the present utility model will be further described with reference to fig. 1 to 4.

The utility model discloses a handle head with an expansion structure, which comprises a handle head 1, wherein the handle head 1 is provided with a square hole 10 for inserting and installing a square locking strip 2, two installation grooves 11 which are correspondingly arranged are arranged on the side wall of the square hole 10, expansion pieces 3 are arranged in the installation grooves 11, the expansion pieces 3 are integrally formed by zinc, aluminum, copper or iron materials, an expansion part 30 protruding out of the installation grooves 11 is arranged at the center of the expansion pieces 3, and protruding parts 31 which are arranged in a wave shape are arranged at the upper end and the lower end of the expansion pieces 3 relative to the expansion part 30. When the square bar 2 is inserted into the square hole 10 by arranging the two expansion pieces 3 in the mounting groove 11, the square bar 2 can be stably fixed in the square hole 10 by being extruded by the expansion part 30 of the expansion piece 3, meanwhile, the expansion part 30 can be compressed in the mounting groove 11 when being extruded by the square bar 2, the convex parts 31 at the upper end and the lower end of the expansion part 30 can be pressed on the square bar 2 to form interference fit when the expansion part 30 is extruded, the expansion piece 3 is prevented from being easily separated from the mounting groove 11, and the structure is more stable.

Further, the expansion sheet 3 is provided with engaging portions 32 having diameters gradually increasing from bottom to top on both sides of the protruding portion 31 below the expansion portion 30.

Through being provided with the card portion of establishing 32 for people are when installing expansion piece 3 in mounting groove 11, can establish the card through the card portion of establishing 32 card of establishing of bellying 31 both sides and establish fixedly in mounting groove 11 both sides, make expansion piece 3 more stable fix in mounting groove 11, be difficult for droing mounting groove 11.

Further, the end of the expansion piece 3 extends out of the square hole 10, and a limit portion 33 is formed by bending one end of the expansion piece 3 extending out of the square hole 10 toward the outside of the handle head 1.

Through being provided with spacing portion 33 for people can be more convenient and fast when the installation, can hold spacing portion 33 during the installation and establish expansion piece 3 card into mounting groove 11 to directly promote expansion piece 3 to mounting groove 11 bottom, limit spacing portion 33 can just laminate and realize spacing effect at handle 1 tip when expansion piece 3 gets into mounting groove 11 completely.

The utility model discloses a handle head 1 can extrude fixedly through two expansion pieces 3 when locking square bar 2 inserts to establish in square hole 10 installation, realizes locking square bar 2's stable installation, improves the whole feel that opens and shuts of tool to lock, uses very comfortablely.

The utility model also provides a technical scheme of the handle 4, which comprises the handle head 1 with the expansion structure.

The above description is only a preferred embodiment of the present utility model, and the protection scope of the present utility model is not limited to the above examples, and all technical solutions belonging to the concept of the present utility model belong to the protection scope of the present utility model.
