DETAILED DESCRIPTION

[0038] The technical solutions in the embodiments of the present application will be described clearly and completely below in combination with the drawings in the embodiments of the present application. Obviously, the described embodiments are only some of the embodiments of the present application, but not all the embodiments. Based on the embodiments in the present application, all other embodiments obtained by those skilled in the art without any creative work fall within the scope of protection of the present application.

[0039] As shown in Figure 1 and Figure 2 The hexagonal wrench 300 provided by the present embodiment includes a receiving member 100 and an adjusting top tight member 200. The receiving member 100 has a first channel 110 and a top hole 130 communicating with the first channel 110. The first channel 110 is used for inserting and placing the hexagonal wrench 300, i.e. one end of the hexagonal wrench 300 is inserted and passes through the first channel 110, and part of the hexagonal wrench 300 is located in the first channel 110. The adjusting top tight member 200 is connected with the receiving member 100, and the adjusting top tight member 200 can move between a first position and a second position. The adjusting top tight member 200 includes a top tight part 210, which extends into the first channel 110 from the top hole 130. By adjusting the position of the adjusting top tight member 200, the top tight part 210 tightens the hexagonal wrench 300 placed in the first channel 110.

[0040] The inner hexagonal wrench 300 provided by the embodiment of the present application is used in the following way: the inner hexagonal wrench 300 is placed in the first channel 110 (the inner hexagonal wrench 300 penetrates the first channel 110), the position of the adjusting and clamping member 200 is adjusted, the clamping portion 210 clamps the inner hexagonal wrench 300 placed in the first channel 110, the clamping portion 210 and the side wall of the first channel 110 opposite to the clamping portion 210 cooperate to extrude and clamp the inner hexagonal wrench 300, the inner hexagonal wrench 300 is locked and fixed in the first channel 110, the inner hexagonal wrench 300 is retracted and fixed on the inner hexagonal force bar, the user can hold the inner hexagonal force bar to operate the inner hexagonal wrench 300, the inner hexagonal wrench 300 is used in cooperation with the inner hexagonal force bar, which is convenient for the user to hold and operate, can effectively increase the operating torque, makes the user tighten or loosen the fastener more labor-saving, improves the work efficiency, and reduces the damage to the screw head. In addition, the adjusting and clamping member 200 can move between the first position and the second position, which realizes that the inner hexagonal wrench 300 force bar can be applied to install inner hexagonal wrenches 300 of different models, has a wide application range, and is suitable for use by the user in different scenes.

[0041] In some embodiments of the present application, the adjusting and clamping member 200 is threadedly connected with the receiving member 100, the adjusting and clamping member 200 is connected with the receiving member 100 through thread cooperation, the position of the adjusting and clamping member 200 can be adjusted by rotating the adjusting and clamping member 200, and the position of the adjusting and clamping member 200 is fixed when the rotation of the adjusting and clamping member 200 is stopped, so that the clamping portion 210 of the adjusting and clamping member 200 can clamp the inner hexagonal wrench 300, which is convenient to operate.

[0042] As shown in the examples of FIGS. 1 and 2, Figure 3 and Figure 4 The top-in hole 130 is arranged at the first end of the receiving member 100, and the first end is provided with an external thread 170. The adjusting and clamping member 200 has a threaded hole 220 matched with the external thread 170 of the first end, one end of the clamping portion 210 is connected to the bottom of the threaded hole 220, the clamping portion 210 extends into the first channel 110 from the top-in hole 130, the adjusting and clamping member 200 is sleeved on the first end of the receiving member 100, the adjusting and clamping member 200 is threadedly connected with the first end of the receiving member 100, the amount of the clamping portion 210 extending into the first channel 110 is controlled by rotating the adjusting and clamping member 200, if the size of the inner hexagonal wrench 300 is large, the clamping portion 210 just extends into the first channel 110 by a small part and cooperates with the side wall of the first channel 110 to extrude and clamp the inner hexagonal wrench 300, if the size of the inner hexagonal wrench 300 is small, the part of the clamping portion 210 extending into the first channel 110 is larger.

[0043] In order to prevent the opening edge of the threaded hole 220 from interfering with the tightening portion 210 tightening the hex wrench 300, the tightening portion 210 extends out of the threaded hole 220 at one end away from the bottom of the threaded hole 220, so that when the position of the tightening member 200 is rotated to adjust the position, the tightening portion 210 first abuts against the hex wrench 300.

[0044] In order to prevent the user from squeezing his hand during the twisting process, the receiving member 100 is provided with at least one first receiving groove 140. The length direction of the first receiving groove 140 (eg Figure 1 The Y direction shown in FIG. 1 is perpendicular to the axial direction of the first channel 110 (as shown in FIG. Figure 1 In the Z direction shown in FIG, one end of the first accommodating groove 140 in the length direction is connected to the first channel 110. The first accommodating groove 140 is configured to accommodate the short side 310 of the hexagonal wrench 300. The arrangement of the first accommodating groove 140 allows the short side 310 of the hexagonal wrench 300 to be sunk into the first accommodating groove 140. Therefore, even if the hexagonal wrench 300 is twisted during operation, the user's hand will not be squeezed.

[0045] Exemplarily, the number of the first accommodating groove 140 is one. Exemplarily, the number of the first accommodating groove 140 is two, and the two first accommodating grooves 140 are located on opposite sides of the receiving member 100, for example, the top and the bottom.

[0046] In some embodiments of the present application, there is one first accommodating groove 140, which is used to accommodate a larger hexagonal wrench 300, such as a hexagonal wrench 300 larger than 5 mm, where the 5 mm hexagonal wrench 300 refers to the distance between two opposing sides of the hexagonal wrench 300. The edge of the first accommodating groove 140 connecting to the first channel 110 is a bevel 160. This bevel 160 provides space for the corner of the hexagonal wrench 300, allowing the short side 310 of the hexagonal wrench 300 to be placed in the first accommodating groove 140 and the long side to be placed in the first channel 110. The sidewall of the first channel 110 connecting to the first accommodating groove 140 is a tightening surface 180, and this tightening surface 180 is parallel to the axial direction of the first channel 110. When the tightening part 210 tightens the hex wrench 300, the first surface of the hex wrench 300 abuts against the tightening part 210, and the surface opposite to the first surface of the hex wrench 300 abuts against the tightening receiving surface 180, and the tightening part 210 and the tightening receiving surface 180 cooperate to clamp and fix the hex wrench 300.

[0047] like Figure 1As shown, in some embodiments of the present application, the receiving member 100 is further provided with a second channel 120, the second channel 120 is arranged intersecting with the first channel 110, and the intersection of the second channel 120 and the first channel 110 is in communication with the top hole 130, that is, the inner hexagonal wrench 300 of the force rod of the present application has two insertion channels of the inner hexagonal wrench 300, one is the first channel 110, and the other is the second channel 120. The inner hexagonal wrench 300 can be inserted into the first channel 110, and the position of the adjusting and clamping member 200 is adjusted to clamp and fix the inner hexagonal wrench 300. The inner hexagonal wrench 300 can also be inserted into the second channel 120, and the position of the adjusting and clamping member 200 is adjusted to clamp and fix the inner hexagonal wrench 300. This arrangement makes the operation of the inner hexagonal wrench 300 force rod more flexible.

[0048] For example, the axial direction of the second channel 120 is perpendicular to the axial direction of the first channel 110.

[0049] Since the specifications and models of the inner hexagonal wrench 300 are more, and the distance between the adjacent two surfaces is large, in order to enable the inner hexagonal wrench 300 of different specifications and models to be clamped and fixed better, the width of the first channel 110 in the circumferential direction of the receiving member 100 is greater than the width of the second channel 120 in the circumferential direction of the receiving member 100. The circumferential direction of the receiving member 100 is the direction around the moving direction of the adjusting and clamping member 200, and the moving direction of the adjusting and clamping member 200 is the length direction of the first accommodating groove 140. This arrangement makes the first channel 110 used for inserting and fixing the inner hexagonal wrench 300 of larger specifications and models, and the second channel 120 used for inserting and fixing the inner hexagonal wrench 300 of smaller specifications and models, thereby enabling the inner hexagonal wrench 300 force rod to clamp and fix the inner hexagonal wrench 300 of different specifications and models better.

[0050] For example, the first channel 110 is configured to accommodate the inner hexagonal wrench 300 of 5mm-10mm specifications, and the second channel 120 is configured to accommodate the inner hexagonal wrench 300 of 1.5mm-5mm specifications. Among them, the inner hexagonal wrench 300 of 5mm-10mm specifications refers to the distance between the two opposite surfaces of the inner hexagonal wrench 300 being 5mm-10mm, and similarly, the inner hexagonal wrench 300 of 1.5mm-5mm specifications refers to the distance between the two opposite surfaces of the inner hexagonal wrench 300 being 1.5mm-5mm.

[0051] In some embodiments of the present application, the receiving member 100 is provided with at least one second accommodating groove 150, the length direction of the second accommodating groove 150 is perpendicular to the axial direction of the second channel 120, one end of the second accommodating groove 150 in the length direction is in communication with the second channel 120, and the second accommodating groove 150 is configured to accommodate the short side 310 of the hex key 300. The provision of the second accommodating groove 150 allows the short side 310 of the hex key 300 to be submerged in the second accommodating groove 150, thereby allowing the user to operate without being squeezed by the hex key 300 even if the hex key 300 is twisted.

[0052] The embodiments of the present application also provide a hex key 300 kit, which comprises a hex key 300 force bar, a wrench frame and a plurality of hex keys 300, the hex key 300 force bar is the hex key 300 force bar of any of the above-mentioned solutions, the wrench frame is detachably connected to the hex key 300 force bar, and each hex key 300 is detachably installed on the wrench frame.
