Description

Technical Field

[0001] The utility model belongs to the technical field of screwdrivers, in particular to a hardware screwdriver. Background Art

[0002] A screwdriver is a common tool used to turn a screw into place, usually with a thin wedge-shaped head that fits into the slot or recess in the screw head.

[0003] The existing screwdrivers have the following defects during use: when working in a narrow operating space or a deep hole, the handle has a limited grip length, making it difficult to apply force to operate, and it is also difficult to firmly clamp the handle with a vise to rotate it, and it is easy to slip. The existing patent document (Announcement No.: CN220592981U) discloses "a hardware screwdriver", which also has the above technical problems. Summary of the invention

[0004] The utility model aims to solve the above-mentioned technical problems existing in the prior art and provides a hardware screwdriver with novel structure, convenient for use with a wrench, applicable to operations in narrow operating spaces or deeper holes, and strong applicability.

[0005] In order to solve the above technical problems, the utility model adopts the following technical solutions:

[0006] A hardware screwdriver comprises a handle and a shank, wherein the handle is arranged on the shank, and the characteristic is that a hexagonal screw head cooperating with a wrench is arranged on the shank, and the hexagonal screw head is fixedly connected to the handle. The screwdriver has a novel structure, is convenient to be used with a wrench, can be used in narrow operating spaces or deep holes, and has strong applicability.

[0007] Furthermore, the hexagonal screw head is fixedly connected to the handle through the expansion portion, which increases the contact area between the hexagonal screw head and the handle, thereby improving the connection strength between the hexagonal screw head and the handle, making it difficult to disengage and reliable to use.

[0008] Furthermore, the handle includes a front end portion and a hand-holding portion, the front end portion is provided with a positioning protrusion, and the hand-holding portion is provided with a positioning groove corresponding to the positioning protrusion. The positioning protrusion and the positioning groove cooperate with each other to achieve accurate docking of the mold core for manufacturing the front end portion and the mold core for manufacturing the hand-holding portion, thereby reducing the difficulty of mold closing and ensuring the molding quality of the handle.

[0009] Furthermore, a casting gap is formed between the front end portion and the hand-grip portion, which facilitates casting and molding of the handle, and the structure is stable and the quality is reliable.

[0010] Furthermore, the hand-grip portion and the knife bar are fixed by bonding, which is reliable and not easy to come off, thus ensuring the connection strength between the handle and the knife bar.

[0011] Furthermore, the front end portion is fixed to the knife rod by bonding, which is reliable and not easy to come off, thereby ensuring the connection strength between the handle and the knife rod.

[0012] Furthermore, the handle is provided with anti-skid grooves, which increase the roughness of the handle surface, thereby improving the friction, making it less likely to slip and more reliable to use.

[0013] Furthermore, the knife bar is provided with a magnetic knife head, which facilitates operation by magnetically absorbing metal fasteners.

[0014] The utility model has the following beneficial effects due to the adoption of the above technical solution:

[0015] 1. When working in a narrow operating space or a deep hole, the grip length of the handle is limited and it is difficult to apply force. At this time, you can use a wrench to hold the hexagonal screw head, turn the wrench to drive the knife rod to rotate, and then tighten the fastener. It is convenient to apply force and improves applicability.

[0016] 2. The positioning protrusion of the front end is matched with the positioning groove of the hand-held part, so that the mold core for manufacturing the front end and the mold core for manufacturing the hand-held part can be accurately matched, which reduces the difficulty of mold closing and ensures the molding quality of the handle.

[0023] like Figures 1 to 4As shown, a hardware screwdriver of the utility model comprises: a handle 1 and a shank 2, wherein the handle 1 is arranged on the shank 2, the handle 1 comprises a front end portion 3 and a hand-held portion 4, the front end portion 3 is provided with a positioning protrusion 5, and the hand-held portion 4 is provided with a positioning groove 6 corresponding to the positioning protrusion 5, and the positioning protrusion 5 is matched and docked with the positioning groove 6 to achieve accurate docking of the mold core for manufacturing the front end portion 3 and the mold core for manufacturing the hand-held portion 4, thereby reducing the difficulty of mold closing, thereby ensuring the molding quality of the handle 1.

[0024] A casting gap 7 is formed between the front end portion 3 and the grip portion 4, which facilitates casting and molding of the handle 1, and has a stable structure and reliable quality.

[0025] A magnetic blade head 8 is provided at the front end of the blade rod 2, which can magnetically attract metal fasteners for easy operation.

[0026] The tail of the tool rod 2 is provided with a hexagonal screw head 9 that cooperates with a wrench. When working in a narrow operating space or a deep hole, the grippable length of the handle is limited and it is difficult to apply force. At this time, the hexagonal screw head 9 can be gripped with a wrench, and the wrench can be turned to drive the tool rod 2 to rotate, thereby tightening the fastener. The force application is convenient and the applicability is improved.

[0027] The hexagonal screw head 9 is fixedly connected to the hand-held portion 4 through the outward expansion portion 11, which increases the contact area between the hexagonal screw head 9 and the handle 1, thereby improving the connection strength between the hexagonal screw head 9 and the handle 1, making it difficult to disengage and reliable to use.

[0028] The front end portion 3 and the knife bar 2 can be fixed by epoxy adhesive, which is reliable and not easy to be separated, thus ensuring the connection strength between the handle 1 and the knife bar 2. The hand-held portion 4 and the outer expansion portion can be fixed by epoxy adhesive, which is fixed front and back, has high reliability, is not easy to be separated, thus ensuring the connection strength between the handle 1 and the knife bar 2.

[0029] The diameter of the hand-held part 4 gradually increases from front to back, which is conducive to applying force and grasping. The hand-held part 4 is provided with an anti-skid groove 10, which increases the roughness of the surface of the hand-held part 4, thereby improving the friction, making it difficult to slip and reliable to use.

[0030] The above are only specific embodiments of the utility model, but the technical features of the utility model are not limited thereto. Any simple changes, equivalent replacements or modifications made based on the utility model to solve basically the same technical problems and achieve basically the same technical effects are all included in the protection scope of the utility model.
