DETAILED DESCRIPTION

[0017] The technical solutions in the embodiments of the utility model will be clearly and completely described in connection with the drawings in the embodiments of the utility model.

[0018] Please refer to Figs. 1-2 The utility model discloses a tightening gun resistance arm, which comprises a stand column 01 for being fixed on a mounting surface, a rear arm 02 perpendicular to each other is installed on the stand column 01, a front arm 03 is rotatably installed at the front end of the rear arm 02, a limiting component for limiting the free rotation of the front arm 03 is arranged between the rear arm 02 and the front arm 03, and a telescopic supporting component 04 for keeping the rear arm 02 horizontal is arranged between the rear arm 02 and the stand column 01. The telescopic supporting component 04 is preferably a spring air cylinder. When the tightening gun is fixed at the end of the front arm 03, the telescopic supporting component 04 between the rear arm 02 and the stand column 01 keeps the tightening gun horizontal. When the limiting component works, the rotation of the tightening gun in the radial direction is limited, so that the tightening gun is prevented from shaking during work. In the conventional state (when the limiting component does not work), the operator can drive the front arm 03 to rotate freely in the radial direction, so that the tightening gun can be rotated to the required position.

[0019] The limiting component comprises a supporting shaft 05 fixedly installed at the end of the rear arm 02 and a connecting disc 06 fixedly installed on the front arm 03. The connecting disc 06 is rotatably installed on the supporting shaft 05 through a bearing, and one side of the supporting shaft 05 is provided with a buckling assembly coupled with the connecting disc 06. When the buckling assembly works, the rotation of the connecting disc 06 around the supporting shaft 05 is limited. When the buckling assembly does not work, the connecting disc 06 rotates freely around the supporting shaft 05.

[0020] The buckling assembly comprises a connecting seat 07 fixedly installed at the end of the rear arm 02, a mounting plate 08 is fixedly installed on the end of the connecting seat 07 through fasteners, a buckling column 09 is fixedly installed on one side of the mounting plate 08, a top plate 10 extending to the direction of the connecting disc 06 and located directly above the mounting plate 08 is fixedly installed on the top of the buckling column 09, a push rod 11 is rotatably installed on the middle part of the buckling column 09, an installation groove is arranged in the middle part of the push rod 11, a lower plate 12 is fixedly installed in the installation groove through fasteners, the lower plate 12 is located between the top plate 10 and the mounting plate 08 and a buckling groove is arranged between the top plate 10, and the outer edge of the connecting disc 06 is located in the buckling groove. A gas cylinder 13 is fixedly installed on the bottom of the mounting plate 08, and the output end of the gas cylinder 13 abuts against the push rod 11. When the output end of the gas cylinder 13 extends, the push rod 11 rotates around the buckling column 09, so that the lower plate 12 moves to the top plate 10 and abuts against and generates friction force on the upper and lower sides of the connecting disc 06 respectively. Thus, the rotation of the connecting disc 06 is limited.

[0021] The lower plate 12 comprises a connecting plate in the mounting groove, and the top of the connecting plate is fixedly provided with the abutting plate 14, which is located outside the mounting groove and outside the push rod 11. Meanwhile, the length of the abutting plate 14 is greater than the width of the push rod 11. When the output end of the cylinder 13 is retracted, the lower plate 12 is prevented from rotating in the push rod 11. When the next use is avoided, the abutting plate 14 and the connecting disc 06 are not fully abutted.

[0022] The rear arm 02 comprises a front mounting seat 15 and a rear mounting seat 16, the front mounting seat 15 is fixedly installed on the column 01, and the connecting seat 07 is fixedly installed on the rear mounting seat 16. Two support rods 17 are arranged between the front mounting seat 15 and the rear mounting seat 16. The two ends of the support rod 17 are rotatably connected with the front mounting seat 15 and the rear mounting seat 16, respectively. Through the arrangement of the two support rods 17, the front arm 03 can move up and down.

[0023] The support rod 17 comprises a connecting rod and a fixed rod 18 installed at both ends of the connecting rod, and the fixed rod 18 and the connecting rod are arranged vertically. The front mounting seat 15 and the rear mounting seat 16 are both provided with a through groove matched with the length of the fixed rod 18. The fixed rod 18 is rotatably installed in the through groove.

[0024] In use, the tightening gun is first installed on the end of the front arm 03, and then the output end of the cylinder 13 is in the retracted state. The front arm 03 can freely rotate around the support shaft 05, and when it is rotated to the required angle, the output end of the cylinder 13 is extended. By driving the lower plate 12 in the buckle assembly to move towards the upper plate 10, the lower plate 12 and the upper plate 10 are in contact with the connecting disc 06, and a friction force is generated to limit the front arm 03 to be fixed at different positions.

[0025] If the embodiment of the utility model has directionality indication (such as up, down, left, right, front, back), the directionality indication is only used to explain the relative position relationship, movement condition and the like between components in a certain specific posture (as shown in the drawing), if the specific posture changes, then the directionality indication also changes accordingly.

[0026] The above embodiments only describe the preferred embodiments of the utility model, and do not limit the scope of the utility model. Without departing from the design spirit of the utility model, various deformations and improvements of the technical solutions of the utility model made by ordinary engineering technicians in the field shall fall within the protection scope determined by the claims of the utility model.
