Description

Tool handle

This creation is related to tools, especially with regard to a tool handle.

A part of the hand tool includes a rod body having a driving head at one end. In use, the user needs to rotate the rod body along its axis, thereby driving a tool member to rotate. The hand tool of the prior art is integrally wrapped on the rod body with an outer layer, so that the user can hold the rod body to tighten or loosen the workpiece.

However, the outer layer of the prior art is usually injection molded from a plastic material; when the work tool is operated, the force (including the driving force and the reaction force of the workpiece) is easily absorbed by the outer layer to reduce the conduction of the force. Moreover, since the torsion force is easy to act on the joint of the rod body and the outer layer during operation, the outer layer is only coated with a single layer and is easily damaged by long-term stress, thereby reducing the service life.

Therefore, it is necessary to provide a novel and progressive tool handle to solve the above problems.

The main purpose of this creation is to provide a tool handle that effectively transmits force.

In order to achieve the above object, the present invention provides a tool handle provided with a grip portion, the tool handle comprising: a metal base disposed on the grip portion, the metal base body being provided with a jack for driving a drive rod And at least two ribs extending radially outside the socket, each of the ribs including a bridging portion and a grip plate, the bridging portion extending radially and connected to the grip plate, the grip plate extending circumferentially a size larger than a circumferential extent of the bridging portion; a covering body covering the metal substrate, the covering body being at least partially embedded in a groove between the adjacent two ribs; wherein each of the grip plates has at least a partial diameter The coating body is exposed.

The following is a description of possible implementations of the present invention by way of example only, and is not intended to limit the scope of the creation of the present invention.

Referring to FIGS. 1 through 4, a preferred embodiment of the present invention is shown. The tool handle 1 of the present invention is provided with a grip portion 3 including a metal base 10 and a covering body 20.

The metal base 10 is disposed on the holding portion 3, and the metal base 10 is provided with a socket 11 through which a driving rod 2 can be disposed, and a rib 12 extending at least twice outside the insertion hole 11, the driving rod 2 may have a driving head such as a flat shape, a cross type, and the like, and may have a radially extending wing portion to be radially engaged with the insertion hole 11. Each of the ribs 12 includes a bridging section 16 and a gripping plate 13 extending radially and connected to the gripping plate 13. The gripping plate 13 extends circumferentially larger than the bridging section 16 to extend circumferentially. Dimensions; the covering body 20 covers the metal base 10, and the covering body 20 is at least partially embedded in a groove 19 between the adjacent two ribs 12; wherein each of the holding plates 13 is at least partially exposed radially Covering body 20. Thereby, the force can be effectively transmitted through the ribs 12, and the covering body 20 can be fastened to the metal base 10 and has a long service life. In this embodiment, the metal substrate 10 is an aluminum alloy, so that the structural strength is high and the force can be effectively transmitted; in other embodiments, other metals can also be used. In the embodiment, the covering body 20 is a plastic material, which can provide better grip comfort. In other embodiments, the covering body may be an elastic material such as a thermoplastic rubber composite or an oil-resistant thermoplastic rubber composite.

The covering body 20 is affixed to the metal base 10 so that the two can be fastened without being rotated or slipped with each other. Preferably, the covering body 20 is a soft covering body, and the soft covering body and the holding plate 13 of each of the ribs 12 cooperate to form a holding surface, so that the hand can be held when the holding surface is gripped At the same time, the force and comfort are felt. In the embodiment, the grip surface is the outer peripheral surface of the tool handle 1.

The bridging section 16 is slightly identical in axial extent to the gripping plate 13 to provide a preferred support force.

The number of the at least two ribs 12 is plural, and the plurality of ribs 12 are circumferentially equally spaced so that the force can be evenly distributed. Further, the holding plates 13 of the at least two ribs 12 are spaced apart.

The metal base 10 further includes a ring portion 18, which may be a continuously closed ring body or a discontinuous ring body. The insertion hole 11 is disposed in the ring portion 18, and the at least two rib portions 12 are looped on the ring portion 18. The ring portion 18 and each of the ribs 12 are integrally formed on the outer circumference of the ring portion 18. Preferably, the curvature of the ring portion 18 is smaller than the curvature of the grip plate 13 of each of the ribs 12.

Preferably, the holding plate 13 at least partially abuts against the covering body 20 to enhance the supporting effect. In addition, the holding plate 13 is provided with at least one first hooking structure 14 , and the covering body 20 is provided with at least one second hooking structure 21 which is reversely coupled with the at least one first hooking structure 14 in the radial direction. The number of the at least one first and second hook card structures is plural, so that the connection effect between the holding plate 13 and the covering body 20 can be improved, so that the holding plate 13 is not easily separated from the covering body 20.

The grip plate 13 is a radially convex arc-convex plate; in the embodiment, the grip plates 13 of the plurality of ribs 12 have the same curvature, thereby providing better grip comfort and facilitating operation. In other embodiments, the grip plate 13 can be a non-arc convex surface such as an angular surface, a flat surface, or the like. In the embodiment, the holding plate 13 is provided with a concave-convex structure 15, such as a wavy structure, to facilitate gripping and to improve friction. In other embodiments, the grip plate 13 can also be, for example, a sand surface, a mesh structure, and other structures that can enhance friction.

The outer circumference of the covering body 20 is provided with at least one groove 22, and the holding plate 13 of the at least one rib 12 is received in one of the grooves 22. In the embodiment, the number of the at least one groove 22 is plural; In addition, each of the grooves 22 is radially recessed; thus, each of the holding plates 13 can be stably fixed and does not easily slide relative to the covering body 20.
