In the following, the embodiment of the hand tool structure and the combination method of the present invention will be further described with reference to the related drawings. In order to facilitate the understanding of the embodiments of the present invention, the same components are denoted by the same reference numerals.

A hand tool structure of the present invention, as shown in Figures 1 and 2, includes a wrench body 10, a tool head 20, and two bolts 30.

The wrench body 10 has a holding section 12 and a carrying section 14 at opposite ends thereof.

The grip portion 12 provides a user's grip and force.

The carrier portion 14 has two pivot arms 142 and a half circular groove 144. The two pivot arms 142 are symmetrically formed to extend outwardly from the grip portion 12, and respectively have locking holes 1422 formed through the pivot arms 142 concentrically. The semicircular groove 144 is defined by two pivot arms 142 and is formed between the two pivot arms 142. The center 144A of the semicircular groove is located on the axis 1422A of each of the locking holes 1422 extending concentrically. In addition, the groove wall of the semicircular groove 144 The center 144A of the concentric semicircular groove forms a concave curved surface 1442 according to a predetermined curvature. In implementation, the center 144A of the semicircular groove 144 is positioned lower than the free end face of each pivot arm 142.

The tool head 20 includes a ratchet ring 22 and a shaft head set 24 that are sleeved with each other.

The ratchet ring 22 has a hollow outline and is pivotally disposed on the carrying portion 14 and received in the semicircular groove 144 such that the outer peripheral surface thereof matches the concave curved surface 1442 of the semicircular groove 144 (but not The ratchet ring 22 has a ratchet row 222, two pivot holes 224, and a convex curved surface 226.

The aforementioned ratchet row 222 is formed along the inner annular wall of the ratchet ring 22.

Each of the pivot holes 224 is recessed from each other and formed on the outer wall of the radial end of the ratchet ring 22, and the axis of each of the pivot holes 224 extending concentrically overlaps the center of the ratchet ring 22.

The convex curved surface 226 matches the curvature of the concave curved surface 1442 of the semicircular groove 144 and is formed on the radially outer annular wall of the ratchet ring 22.

The shaft head set 24 (known in the art) includes an axially extending ratchet ring 22 that is coupled to and engages with a shaft head 242 and a shaft button 244.

The bolts 30 are screwed into the respective pivot holes 224 of the ratchet ring 22 to pivotally connect the ratchet ring 22 to the respective pivot holes 224 of the ratchet ring 142.

Therefore, the above is a manual embodiment of the present invention. Referring to the various components of the structure, the assembly method of each component of the present invention will be further described below.

Since the outer ring wall of the ratchet ring 22 has a convex curved surface 226, and the semicircular groove 144 of the wrench body has a concave curved surface 1442, the ratchet ring 22 and the semicircular groove 144 of the wrench body 10 are inserted, and the feeding sleeve cannot be fed in any direction. Therefore, the combination method of the hand tool structure of the present invention, as shown in Figures 3 to 8, includes:

Step 100: Take a wrench body 10 and a ratchet ring 22.

Step 200: Feed the ratchet ring 22 in a radial end face into the semicircular groove 144 of the load-bearing section 14 of the wrench body 10 (as shown in Fig. 4).

Step 300: Adjust the position of the ratchet ring 22 in the semicircular groove 144 so that the center of the ratchet ring 22 overlaps or approaches the center 144A of the semicircular groove of the wrench body 10 (as shown in Fig. 5).

Step 400: The torsion ring 22 is twisted such that the convex curved surface 226 of the outer annular wall is tangent to the concave curved surface 1442 of the semicircular groove 144, and the force is applied to force the ratchet ring 22 along the concave curved surface 1442 of the semicircular groove 144 until the spine The pivot holes 224 of the ring gear 22 are matched to the position of the lock holes 1422 of the pivot arms 142 (as shown in FIGS. 6 to 8).

Step 500: The two bolts 30 are respectively screwed into the locking holes 1422 of the pivot arms 142, and respectively extend into the pivot holes 224 of the ratchet ring 22 to pivotally connect the ratchet ring 22 (as shown in FIG. 1). Show).

Step 600: Take a shaft head 242 and a shaft button 244 respectively and axially extend the ratchet ring 22 to form a joint, and interact with the ratchet row 222 of the ratchet ring 22 (as shown in Figures 1 and 2). In practice, this step can be implemented after step 100.

With the hand tool formed by the hand tool structure and the combination method thereof, the sleeve 242 can be sleeved with different sizes of sleeves (not shown) to match the size of the screw lock workpiece (not shown). And carry out operations such as disassembly and assembly.

When the shaft head 242 is connected to the sleeve, the user can hold the wrench body The grip portion 12 of the 10 is biased to interlock the tool head 20 (the ratchet ring 22, the shaft head group 24), and the ratchet ring 22 is fitted into the semicircular groove 144 of the wrench body 10 (the carrier portion 14), and The surface of the wrench body 10 or the reaction force of the tool head 20 (the ratchet ring 22 and the shaft head group 24) is dispersed in the convex curved surface 226 and the semicircle of the ratchet ring 22. The concave curved surface 1442 of the groove 144 avoids the loss of the conventional turning head hand concentrated on the pivot 96 (as shown in Figures 9, 10).

The above description is only for the preferred embodiment of the present invention, and is intended to clarify the features of the present invention, and is not intended to limit the scope of the embodiments of the present invention. Changes that are well known to those skilled in the art are still within the scope of the invention.
