The top base 23 is located below the suspension base 11 and connected to the bottom end of the input shaft 131. The top and bottom ends of the pair of second telescopic links 22 are respectively connected to the top seat 23 and the intermediate seat 24, the upper portion of the first telescopic link 21 is located between the pair of second telescopic links 22, the first telescopic link 21 passes through the intermediate seat 24, and the bottom end of the first telescopic link 21 is connected to the base 25.
In a specific embodiment, the first telescoping rod 21 includes a sleeve 211, a guide bar 212, a cross pin 213, and a pair of rollers 214. The sleeve 211 passes through the intermediate seat 24, and the top of the guide rod 212 is axially movably disposed in the sleeve 211, and the bottom end of the guide rod 212 is connected to the base 25. The transverse pin 213 passes transversely through the top of the guide bar 212 (the top of the guide bar 212 is provided with a pin hole 2120), and a pair of rollers 214 are respectively mounted at both ends of the transverse pin. The two opposite sides of the sleeve 211 are respectively provided with a first vertical waist hole and a second vertical waist hole, and a pair of rollers 214 are respectively arranged in the first vertical waist hole and the second vertical waist hole in a rolling manner. The structure can achieve better torsion resistance effect, so that a worker can operate the tightening gun to tighten the screw more labor-saving. Further, the first telescopic link 21 further includes a locking mechanism that can lock the position of the guide bar 212, and the locking mechanism may be, for example, but not limited to, a tightening screw that penetrates the sleeve 211 to limit the guide bar 212 to slide up and down within the sleeve 211.
In a specific embodiment, the second telescoping rod 22 includes an outer tube 221, a slide rod 222, and a locking mechanism that locks the position of the slide rod 222. The top end of the outer tube 221 is connected with the top seat 23, the upper part of the sliding rod 222 extends into the outer tube 221, and the bottom end of the sliding rod 222 is connected with the middle seat 24. The locking mechanism may be, for example, but not limited to, a jack screw that passes through the outer tube 221 to limit the sliding bar 222 from sliding up and down within the outer tube 221.
Further, the elevating assembly 2 further includes a first balancer 27 and a pair of second balancers 28.

A bolt hole 330 is provided on a side surface of one end of the rotation shaft 33; the mounting interface 411 is provided laterally with a spring latch 43 comprising a latch that is retractable between an extended position and a retracted position and a spring (the latch and spring are not shown) that biases the latch from the retracted position towards the extended position. One end of the swivel shaft 33 is inserted into the insertion hole 413, and the aforementioned pin is inserted into the pin hole 330 to lock the gun rack 41 to the gun rack connector 3. When it is desired to replace the tightening assembly with another torque, the current tightening assembly 4 can be removed from the gun rack connector 3 by pulling the spring bolt rearward to move the bolt from the extended position to the retracted position against the biasing force of the spring, whereupon the bolt is withdrawn from the bolt hole 330 of the rotatable shaft 33.
When the embodiment of the utility model is used, the suspension assembly 1 can be hoisted on the lifting beam, so that the labor burden of workers in operation is reduced. In operation, the tightening position of the tightening gun 42 can be changed by adjusting the rotation position of the input shaft 131, the lifting positions of the first telescopic rod 21 and the second telescopic rod 22, and the rotation position of the gun rack 41 along with the rotation shaft 33, so as to flexibly adapt to different tightening stations. And moreover, the screw is screwed by the screwing gun, so that the screwing gun can record and store working parameters, and the assembly efficiency is improved.
