The invention provides a bevel gear transmission multipurpose wrench, aiming at the problem that the conventional wrench cannot realize large-amplitude swing and limit the use occasions due to the problem of shape or volume, and effectively solving various existing problems. The designed bevel gear transmission multipurpose wrench adopts bevel gear transmission, is suitable for the operation of a narrow space on a bolt or a nut, and effectively solves the problem that torque force cannot be provided for the bolt or the nut under the condition that the space is limited.
In order to achieve the purpose, the technical scheme of the invention is that the bevel gear transmission multipurpose wrench comprises a torque bevel gear, a transmission bevel gear, a sleeve joint, a connecting rod and a handle, wherein the sleeve joint is arranged in a central through hole of the torque bevel gear; the horizontal side of the torsional bevel gear is connected with the vertically arranged transmission bevel gear; the connecting rod is arranged on one side, away from the torsional bevel gear, of the transmission bevel gear; the handle is arranged on one side, away from the transmission bevel gear, of the connecting rod; a first operating rod slot is formed in one side, away from the connecting rod, of the handle;
the extension handle is arranged, second operation rod slots are arranged at two axial ends of the extension handle, and the second operation rod slots are matched with the first operation rod slots. The first operating rod slot can be inserted with a lever therein to increase the torque of the rotating handle; the extension handle and the handle are fixed by the second operating rod slot, and the length of the handle is extended.
In a preferable mode, the torsion bevel gear, the transmission bevel gear and the connecting rod are arranged in the support frame to play a role in protecting the gear, but the rotation of each component is not influenced.
In an optimal mode, the torsion bevel gear is in gear transmission with the transmission bevel gear; the torsional bevel gear is fixed with the sleeve joint; the transmission bevel gear, the connecting rod and the handle are fixed.
Compared with the prior art, the invention has the following advantages and positive effects: the transmission is carried out by the horizontally arranged torque bevel gear and the vertically arranged transmission bevel gear, so that the transmission device is suitable for controlling the butt bolts or nuts in a narrow space, and is provided with the extension handle to increase the application range.
Specifically, the beneficial effects are as follows:
1. a bevel gear transmission multipurpose wrench comprises a torque bevel gear and a transmission bevel gear which are used for transmission, the structure is compact, the space required for transmitting the same torque is the smallest compared with a conventional wrench, the operation space is saved, the transmission efficiency is high, and the using performance is stable and reliable. The support frame is arranged, the main parts are protected, meanwhile, the rotation of each part is not influenced, and the service life of the wrench is prolonged.
2. A bevel gear transmission multipurpose wrench is provided with a first operating rod slot, and a lever can be inserted into the first operating rod slot if force cannot be applied during use, so that the torque of a rotating handle is increased; the extension handle is provided with the second operating rod slot, the extension handle and the handle are fixed, the usable range of the wrench is enlarged, and torque can be further increased to a certain degree.
Drawings
Fig. 1 is a plan view of a bevel gear transmission multipurpose wrench.
In the figure, 1 is a torsion bevel gear, 2 is a transmission bevel gear, 3 is a socket joint, 4 is a support frame, 5 is a connecting rod, 6 is a handle, 7 is a first operating rod slot, 8 is an extension handle, and 9 is a second operating rod slot.
Detailed Description
The present invention will be described in further detail with reference to the accompanying drawings and examples.
As shown in fig. 1, a bevel gear transmission multipurpose wrench comprises a torque bevel gear 1, a transmission bevel gear 2, a socket joint 3, a connecting rod 5 and a handle 6, wherein the socket joint 3 is arranged in a through hole in the center of the torque bevel gear 1; one horizontal side of the torsional bevel gear 1 is connected with the vertically arranged transmission bevel gear 2; the connecting rod 5 is arranged on one side, away from the torsional bevel gear 1, of the transmission bevel gear 2; the handle 6 is arranged on one side, away from the transmission bevel gear 2, of the connecting rod 5; a first operating rod slot 7 is formed in one side, far away from the connecting rod 5, of the handle 6;
the extension handle 8 is arranged, the second operating rod inserting grooves 9 are formed in two axial ends of the extension handle 8, and the second operating rod inserting grooves 9 are matched with the first operating rod inserting grooves 7.
The torsional bevel gear 1, the transmission bevel gear 2 and the connecting rod 5 are arranged inside the support frame 4.
