It should be noted that, the sliding direction of the sleeve 149 is up and down sliding, when the connecting frame 141 is installed on the shaft frame 3, the sleeve 149 slides relative to the connecting frame 141 under the action of gravity and covers the nut which is pre-tightened; even if the sleeve 149 is not smoothly covered on the pre-tightened nut, the rotation of the bolt drives the nut which is not fixed to rotate along with the rotation of the bolt driven by the tightening mechanism 17, so that the nut can smoothly enter the fixing hole; therefore, the sleeve 149 is sleeved on the periphery of the nut, manual operation of workers is basically not needed, and the operation process of the workers is simplified.
According to an embodiment of the present invention, the inner wall of the fixing groove 182 near the top thereof protrudes inward to form a limiting protrusion, so as to prevent the nut from rising to be separated from the limit of the fixing groove 182 during the tightening process. It should be noted that the limiting boss does not close the opening above the fixing groove 182, but reserves a space for the bolt to pass through.

According to an embodiment of the present invention, the number of the clamping members 144 is at least two, each clamping member 144 has a corresponding clamping hole 32, and by providing at least two clamping members 144 to be clamped and matched with the corresponding clamping holes 32, each clamping member 144 and the corresponding clamping hole 32 can also be clamped and matched to position the connecting frame 141, thereby ensuring the positioning of the sleeve 149 and the corresponding nut, and further ensuring that the sleeve 149 can be smoothly sleeved on the nut.
According to another embodiment of the present invention, the connecting frame 141 further comprises at least two handle members 148, and preferably two handle members 148 are provided, so that the two handle members 148 are provided to facilitate the grasping of the working person.
The first fixing assembly 14 further includes a first elastic member 151, one end of the first elastic member 151 is connected to the sliding member 147, the other end of the first elastic member 151 is connected to the sleeve 149, and the first elastic member 151 is used to drive the sleeve 149 to move toward the nut. The first elastic element 151 may be a spring, wherein the spring may be a gas spring or a compression spring, etc., and the spring is in a compressed state and applies a force to the sleeve 149 in a direction close to the nut to push the sleeve 149 to cover the nut; after the joint piece 144 and the joint hole 32 are in joint fit, the sleeve 149 is close to the nut under the action of gravity and spring elasticity, if the sleeve 149 is not smoothly covered on the nut, then when the tightening mechanism 17 drives the bolt to rotate, compared with the case that the sleeve 149 is only under the action of gravity, the sleeve 149 can be smoothly covered on the nut because the sleeve 149 simultaneously bears the action of gravity and elasticity. It should be noted that the connecting member 143, the sleeve 149 and the nut are all located above the well-shaped frame 3, so that the direction of the elastic force applied to the sleeve 149 is substantially the same as the direction of the gravity applied to the sleeve 149.
