Embodiment 1

[0022] Such as figure 1 As shown, the dismounting wrench of the outer hexagonal bolt of the present invention includes a clamping part 1 for fixing the bolt, and the bottom of the clamping part 1 is provided with an opening for the outer hexagonal bolt nut to enter the inside of the clamping part 1, and the clamping part 1 A vacuum chuck 2 is arranged inside, and the suction rod of the vacuum chuck 2 is located above the clamping part 1, and a rotating rod 3 is also connected above the clamping part 1, and the rotating rod 3 is controlled by a motor 4 installed at one end of the rotating rod 3 When it rotates, a lower cover 5 is connected below the clamping part 1, and the lower cover 5 is hinged to a bottom edge of the clamping part 1, and the center of the lower cover 5 is provided with a through hole for the outer hexagonal bolt screw to pass through. 6. The lower cover 5 is composed of a cover plate A and a cover plate B hinged to the cover plate A, and both the cover plat...

Embodiment 2

[0025] Based on Embodiment 1, a hand-held handle is also connected above the clamping portion 1, and the hand-held handle includes a cross bar 7, and both ends of the cross bar 7 are connected with vertical rods 8, and the vertical rod 8 rotates with the clamping portion 1. Connected, the rotating rod 3 passes through the cross bar 7 and is connected with the clamping part 1 . The hand-held handle is used to fix and support the clamping part, the cross bar is for the user to hold, and the vertical bars at both ends of the cross bar are convenient for the user to adjust the position of the clamping part, and the force distribution of the user acting on the clamping part is more uniform. The hand-held handle in the present invention is a simple and practical support device for the support clip device.

Abstract

The invention discloses a dismantling wrench for an outer hexagonal bolt, which includes a clamping portion for fixing the bolt, the bottom of the clamping portion is provided with an opening for the nut of the outer hexagonal bolt to enter the interior of the clamping portion, and the interior of the clamping portion is provided with a vacuum suction cup , the suction rod of the vacuum suction cup is located above the clamping part, and a rotating rod is connected above the clamping part. The rotation of the rotating rod is controlled by a motor installed at one end of the rotating rod. One bottom edge of the clamping part is hinged, and the center of the lower cover is provided with a through hole for the outer hexagonal bolt and screw to pass through. The lower cover is composed of a cover A and a cover B hinged with the cover A. The cover A, the cover The boards B are provided with grooves forming through holes. The present invention can firmly fix the nut of the bolt inside the clamping part through the interaction between the vacuum suction cup and the lower cover, and the nut and the inside of the clamping part will not slide relative to each other, and the bolt will not be separated during the rotation process. clamping part.

Description

technical field [0001] The invention relates to a wrench, in particular to a wrench for removing hexagonal bolts. Background technique [0002] A wrench is a commonly used disassembly and installation tool. Hand tools for turning bolts, screws, nuts, and other open or socketed fasteners whose threads hold bolts or nuts tightly by the principle of leverage. The wrench is usually formed with a clamping handle at one or both ends of the handle to apply an external force to the handle to twist the bolt or nut to hold the opening or sleeve of the bolt or nut. When in use, an external force is applied to the shank in the direction of thread rotation, so that the bolt or nut can be twisted. [0003] At present, the wrench is generally rotated manually, which is more convenient to disassemble the tool, but it is not convenient to install the workpiece; in the process of turning the wrench, if the bolt and the wrench are not fixed tightly when the bolt is tightened, the position of...
