[0045] Please refer to Figure 1, is a three-dimensional diagram of a hand tool 100 according to an embodiment of the present utility model. The hand tool 100 comprises a handle 110, a drive head 120 and a stopper 130. The drive head 120 is pivotally connected to one end of the handle 110, and the stopper 130 is disposed at the end of the handle 110. Specifically, the hand tool 100 is a swing head wrench, the drive head 120 can pivot relative to the handle 110, and the drive head 120 and the handle 110 can be positioned at a preset angle by the stopper 130. In this way, the preset angle between the drive head 120 and the handle 110 can be appropriately adjusted in accordance with workpieces in different positions, so that the user can apply force more smoothly. It must be noted that the present utility model is not limited to the swing head wrench disclosed in the accompanying drawings and embodiments, and can be any hand tool with an angle adjustment requirement between the drive head and the handle.

[0046] Depend on Figure 1 , Figure 2 As can be seen, the handle 110 includes a step difference structure 112, which is located at one end of the handle 110 where the drive head 120 is pivotally connected, wherein the step difference structure 112 can be integrally formed with the handle 110 to simplify the components of the hand tool 100, but the utility model is not limited thereto. The drive head 120 includes a positioning portion 122, which is located at one end of the drive head 120 facing the handle 110. The stopper 130 includes a stopper structure 131, which is located at one side of the stopper 130 facing the drive head 120. Figure 3 As shown, the stop structure 131 of the stopper 130 and the positioning portion 122 of the driving head 120 are engaged with each other, so that the driving head 120 and the handle 110 are positioned at a preset angle.

[0047] In detail, the drive head 120 includes a pivoting portion for being pivotally connected to the end of the handle 110. One end of the handle 110 includes two lugs 111. The pivoting portion of the drive head 120 has a pivot hole 121, and the two lugs 111 may respectively have a pivot hole 1111, so that the drive head 120 and the handle 110 can be relatively pivoted by a pivot member 101 penetrating the pivot hole 121 of the pivoting portion and the pivot hole 1111 of the lug 111. Furthermore, the positioning portion 122 of the drive head 120 includes a plurality of first tooth structures, which are arranged around the outer surface of the pivoting portion. The stop structure 131 of the stop member 130 includes at least one second tooth structure, which is engaged with at least one of the first tooth structures. In other words, the first tooth structure and the second tooth structure are locked against each other, so that the driving head 120 and the handle 110 cannot pivot relative to each other and are fixed at a preset angle.

[0048] Mate Reference Figure 4 , Figure 5 as well as Figure 6 , respectively Figure 1 Schematic diagram of the positions of the stop structure 131 and the positioning portion 122 in different states of the embodiment. Figure 2, Figure 4 It can be seen that the stopper 130 can be pushed by the step structure 112 of the handle 110. When the driving head 120 and the handle 110 are relatively located at a preset angle, the stopper structure 131 is locked against the positioning portion 122 of the driving head 120, and the first tooth structure and the second tooth structure are meshed with each other, so that the driving head 120 and the handle 110 are positioned at the preset angle. This facilitates the operation of the hand tool 100 in different environments.

[0049] Depend on Figure 2 , Figure 5 and Figure 6 It can be seen that the hand tool 100 further includes an auxiliary structure 140, wherein the handle 110 has a concave hole 113, which is located at one end of the handle 110 and adjacent to the step structure 112, and the auxiliary structure 140 can be protrudingly disposed in the concave hole 113. The auxiliary structure 140 includes an elastic member 141 and a push member 142, wherein one end of the elastic member 141 is positioned in the concave hole 113, and the push member 142 is connected to the other end of the elastic member 141. When the elastic member 141 is not compressed, the push member 142 will slightly protrude from the concave hole 113 (such as Figure 4 , Figure 5 Specifically, the elastic member 141 of the present invention is a spring, and the push member 142 is a steel ball, but the present invention is not limited thereto.

[0050] like Figure 5 As shown, when the user wants to change or adjust the positioning of the driving head 120 and the handle 110 to a preset angle, the stopper 130 can be first displaced along the axial direction parallel to the pivoting portion (i.e., the axial direction of the pivot member 101) toward the end of the positioning portion 122 away from the step structure 112. At this time, the stopper 130 will be located above the auxiliary structure 140 and contact the abutting member 142.

[0051] like Figure 6 As shown, when the user drives the stopper 130 to push the abutting member 142 toward the handle 110 away from the drive head 120, the positioning portion 122 can be disengaged from the abutment of the stopper structure 131, so that the drive head 120 and the handle 110 can pivot relative to each other again. At this time, the user can change the preset angle between the drive head 120 and the handle 110, and then apply it to different operating positions or environments as needed. In addition, after the user adjusts the drive head 120 and the handle 110 to the preset angle, the stopper 130 is released, and the elastic member 141 can use its restoring force to drive the abutting member 142 to push against the stopper 130, so that the first tooth structure and the second tooth structure are meshed with each other (return to the original position). Figure 5 Then, the stopper 130 is pushed back to the position relative to the step-difference structure 112 (i.e. Figure 4 state), the hand tool 100 can be stably operated again.

[0052] Please refer to Figure 7 The driving head 120 and the handle 110 may be located at different preset angles, but the present invention is not limited thereto.

[0053] In particular, Figure 3 , Figure 4 , Figure 5 as well as Figure 6 It can be seen that each first tooth structure of the positioning portion 122 extends from one end of the positioning portion 122 to the other end of the positioning portion 122 along a direction parallel to the axial direction of the pivoting portion (i.e., the axial direction of the pivot member 101). Therefore, when the stopper 130 is displaced by the push of the step difference structure 112, and then pushes against the auxiliary structure 140 to release the preset angle fixed between the drive head 120 and the handle 110 and completely disengages from the positioning portion 122, if the drive head 120 and the handle 110 are to be positioned at another preset angle, the push member 142 of the auxiliary structure 140 can be first moved toward the drive head 120, so that the second tooth structure is meshed with the first tooth structure again, and then displaced toward the other end of the positioning portion 122 along a direction parallel to the axial direction of the pivoting portion, and after being pushed and positioned by the step difference structure 112, the preset angle between the drive head 120 and the handle 110 can be fixed. In other words, the design of the first tooth structure extending from one end to the other end of the positioning portion 122 can reduce the problem of tooth alignment when the stop structure 131 is disengaged and is intended to be positioned, thereby improving the convenience and smoothness of operation.

[0054] Furthermore, with reference Figure 5 The length L2 of the second tooth structure is greater than one third of the length L1 of the first tooth structure and less than half of the length L1 of the first tooth structure. In this way, the problem of tooth alignment can be reduced during operation, and the positioning strength of the stop structure 131 and the positioning portion 122 can be improved. Figure 3 and Figure 5 It can be seen that the thickness of the ratchet teeth of the first tooth structure of the positioning portion 122 is x, and the thickness of the step-difference structure 112 is TH, which satisfies the following condition: 0.5x≤TH≤0.95x. Thus, the positioning strength is further improved.

[0055] In addition, since the stopper structure 131 of the stopper 130 must be disposed between the drive head 120 and the handle 110, the volume must be maintained at a size that does not affect the relative pivoting of the drive head 120 and the handle 110, which may easily lead to the problem that the volume is too small and it is not easy to adjust its position. Figure 2The stopper 130 of the present invention further includes two operating parts 132, which are respectively connected to the two ends of the stopper structure 131 and are located on both sides of the handle 110. Furthermore, each operating part 132 includes a protruding structure 1321 on both sides. The operating part 132 is arranged across the handle 110 so that it is exposed outside the handle 110, which helps the user to drive the displacement of the stopper structure 131. In addition, with the arrangement of the protruding structure 1321, the user can push the two operating parts 132 synchronously with the thumb and index finger, making the operation smoother.

[0056] In summary, the hand tool provided by the utility model mainly has the following advantages. 1. Through the setting of the step difference structure, the preset angle between the drive head and the handle can be positioned by pushing the stopper with a single component, which simplifies the configuration of the hand tool elements, can effectively reduce its weight and reduce the manufacturing cost. 2. The design of the first tooth structure extending from one end of the positioning part to the other end can reduce the tooth matching problem between the second tooth structure of the stop structure and the first tooth structure, and improve the smoothness of the operation. 3. The design of the operating part of the stopper can further improve the convenience of the user in changing the preset angle between the handle and the drive head.

Any person with ordinary knowledge in the technical field may make some changes and modifications without departing from the spirit and scope of the present invention. Therefore, the protection scope of the present invention shall be determined by the scope of the attached patent application.
