Detailed ways

The technical solution of the utility model is described in further non-limiting detail below in combination with preferred embodiments and accompanying drawings.

As shown in Fig. 1 and Fig. 2, a tightening mechanism corresponding to a preferred embodiment of the present invention is used for connecting with an electric tool to tighten or loosen the bolt sunk inside the workpiece. The electric tool may be a tool for screwing screws such as an electric screwdriver or an air screwdriver.

The tightening mechanism of the utility model includes an extension rod 1 , an adapter 2 , a suspension device 3 and a support assembly 7 .

One end of the extension rod 1 is provided with an outer hexagonal head 1a matching the inner hexagonal hole of the bolt head, and the other end is connected with the adapter 2, and the adapter 2 is connected with the chuck of the electric tool.

The suspension device 3 includes a suspension board 4 , a baffle 11 connected to the suspension board 4 and a suspension ring 6 . The baffle plate 11 is used to offset against the side wall of the workpiece, so that the tightening mechanism will not rotate when the screw is screwed; the suspension ring 6 can be connected with the object above (such as the roof) by a rope or the like, so that the tightening mechanism can be suspended In the air, when people are screwing, the gravity of the mechanism and the electric tool can be borne by the rope, thereby saving physical strength. Offer the through hole 5 that matches with the bolt hole on the workpiece on the suspension plate 4, there can be only one through hole 5, also can be provided with a plurality of according to the position of workpiece bolt hole. In this embodiment, the number of through holes 5 is four.

The support assembly 7 includes a support sleeve 8 and a support column 9 , one end of the support column 9 is connected with the suspension plate 4 , and the other end is connected with the support sleeve 8 . In the present embodiment, the quantity of support column 9 is two, and its one end is provided with pin, is provided with the pin sleeve 10 that cooperates with pin around the through hole 5 on the suspension plate 4, and support column 9 is connected to by pin and pin sleeve 10. On the hanging board 4. The two support columns 9 are respectively located on both sides of the through hole 5, and a support sleeve 8 is connected between them, and a mounting hole is opened in the middle of the support sleeve 8, and a bearing that cooperates with the adapter 2 can be installed in the installation hole, so that the adapter 2 rotates more smoothly.

For the convenience of people to hole and move suspension plate 4, a handle 12 is respectively provided with on the opposite side of suspension plate 4. People can conveniently hold the handle 12 to adjust the position of the suspension plate 4 so that the through hole 5 is aligned with the bolt hole on the workpiece.

When in use, first hang the suspension plate 4 with ropes, connect the support assembly 7, the adapter 2, the extension rod 1, and the electric tool to each other, then insert the extension rod 1 into the through hole 5 with the electric tool in hand, and the support assembly 7 and the suspension The plate 4 is connected and fixed through the pin sleeve, and then the extension rod 1 is inserted into the bolt hole of the workpiece to cooperate with the bolt head, and the electric tool is started to lock or loosen the bolt. During operation, the baffle plate 11 can be abutted against the side of the workpiece, so as to reduce the possible follow-up phenomenon of the tightening mechanism.
