Description

A bolt removal tool

technical field

The utility model relates to the technical field of bolt removal tools.

Background technique

When overhauling the bolted joints of the truck compartment, due to the serious corrosion of the bolts, it is difficult to disassemble with ordinary tools. The hexagonal wrench can only clamp the three adjacent planes on the nut, and the dismounting torque can only be located on one side of the nut, which is inconvenient to use. For socket wrenches, simple tools such as pliers are usually used, which are prone to problems such as loose nut clamping and difficult disassembly.

Utility model content

The technical problem to be solved by the utility model is to provide a bolt removal tool, which has the characteristics of simple structure, convenient and quick operation, easy removal of nuts and no damage to threads.

In order to solve the above-mentioned technical problems, the technical solution adopted by the utility model is: a bolt removal tool, including a drill chuck, a key lever and a T-shaped handle; the upper end of the key lever is inserted into the claw adjustment hole, and the The section of the cross bar of the T-shaped handle is rectangular, and the left end of the cross bar is fixed in the center hole at the right end of the drill chuck, and a right-angle wrench is installed between the cross bar and the key bar.

The further improvement of the utility model is: the upper end of the right-angle wrench is provided with a rectangular notch and is stuck on the cross bar, and the left end of the right-angle wrench is provided with a matching hole and is set on the key rod. Also included is a sleeve that fits over the vertical tube at the right end of the T-handle.

The beneficial effects produced by adopting the above technical solution are: the utility model can clamp three planes with equal intervals on the nut, and the nut removal torque is uniform, which can avoid damage to the thread and improve the efficiency of nut removal.

detailed description

Contrasted with Fig. 1-3, the operation steps of the present utility model are further described:

Embodiment 1: A bolt removal tool, including a drill chuck 2, a key lever 8 and a T-shaped handle; the upper end of the key lever 8 is inserted into the claw adjustment hole 3, and the cross bar 4 of the T-shaped handle The cross-section is rectangular, and the left end of the cross bar 4 is fixed in the center hole of the right end of the drill chuck 2, and a right-angle wrench 7 is installed between the cross bar 4 and the key shaft 8. Also include the sleeve pipe 5 that is sleeved on the vertical pipe 6 at the right end of the T-shaped handle. How to use: 1. Put the right-angle wrench 7 on the key lever 8 at ordinary times; 2. Before disassembling the nut, use the key lever 8 to open the claw 1 and clamp the nut; 3. Put the rectangular groove on the upper end of the right-angle wrench 7 Port 9 is set on the cross bar 4; four, hold the sleeve pipe 5 firmly with the right hand, press the right-angle wrench 7 with the left hand, and turn both hands clockwise, because the right-angle wrench 7 transmits the torque, the nut is easy to loosen.

Embodiment 2: A bolt removal tool, including a drill chuck 2, a key lever 8 and a T-shaped handle; the upper end of the key lever 8 is inserted into the claw adjustment hole 3, and the cross bar 4 of the T-shaped handle The cross-section is rectangular, and the left end of the cross bar 4 is fixed in the center hole of the right end of the drill chuck 2, and a right-angle wrench 7 is installed between the cross bar 4 and the key shaft 8. The upper end of the right-angle wrench 7 is provided with a rectangular notch 9 and is stuck on the cross bar 4 , and the left end of the right-angle wrench 7 is provided with a matching hole 10 and is set on the key lever 8 . Also include the sleeve pipe 5 that is sleeved on the vertical pipe 6 at the right end of the T-shaped handle. Using method is identical with embodiment 1.
