Detailed Description

The present application will be described in further detail with reference to the following drawings and examples. It is to be understood that the specific embodiments described herein are merely illustrative of the relevant invention and are not limiting of the invention. It should be noted that, for convenience of description, only the portions related to the present invention are shown in the drawings.

It should be noted that the embodiments and features of the embodiments in the present application may be combined with each other without conflict. The present application will be described in detail below with reference to the embodiments with reference to the attached drawings.

Referring to fig. 1, 2 and 3, a dual-purpose hook wrench includes a front wrench section 1, a slipknot connecting rod 2, a handle 3, an extension rod 4, a rear extension rod section 5, and a replaceable hook 9. Preferably, the synthetic material of the hook wrench is No. 45 steel, the No. 45 steel has beautiful surface and good corrosion resistance, and the hook wrench can play a role in preventing oxidation by performing blackening treatment without surface treatment such as color plating.

As shown in fig. 2: the extension bar 4 is of a rod-shaped structure, one end of the extension bar is provided with a groove 6, and the other end of the extension bar is provided with a screw groove 7.

As shown in fig. 3: the rear section 5 of the extension bar is of a rod-shaped structure, one end of the rear section of the extension bar is provided with a screw 8, and the rear section 5 of the extension bar and the screw 8 are integrally formed. The rear section 5 of the extension bar is arc-shaped, and the radian of the extension bar accords with the ergonomic radian, so that the extension bar is convenient to grasp.

As shown in fig. 1: the head end of the handle 3 is in a crescent hook shape, and the tail end of the handle is in a cuboid structure; the replaceable hook head 9 is fixedly arranged on the front wrench section 1; the front wrench section 1 is connected with the head end of the handle 3 through the slipknot connecting rod 2; the tail end of the handle 3 is arranged at one end of the extension bar 4 in a penetrating way through the groove 6, and the shape of the groove 6 is matched with that of the tail end of the handle 3. The rear section 5 of the extension bar is fixed at the other end of the extension bar 4 through the screw rod 8, and the screw rod 8 is matched with the screw groove 7.
