[0002] In the fields of machinery manufacturing, construction, and installation and maintenance of various equipment, it is often necessary to install nuts on long threaded rods. The traditional installation method mainly relies on manual operation, using tools such as wrenches to screw the nuts onto the long threaded rods one by one. This method has many disadvantages:

[0003] 1. Inefficiency: Manually tightening nuts, especially when installing multiple nuts on long threaded rods, requires a lot of time and manpower, which greatly affects the work progress;

[0004] 2. High labor intensity: Long-term and repeated twisting actions will cause fatigue in the operator's hands and arms, which can easily lead to physical discomfort and reduce work quality;

[0005] 3. High precision requirements: Manual operation is difficult to ensure that the tightening force of each nut is uniform, which may affect the stability and reliability of the entire installation structure.

[0006] Although there are some automated nut installation devices on the market, most of these devices are large in size and complex in structure. They need to be fixed on a specific workbench for use, and are not suitable for operation in places with limited space and complex working environments. They are not flexible enough for installing nuts on long threaded rods. Therefore, there is an urgent need for a handheld device that can use common tools (such as an electric drill), is easy to carry and easy to operate, so as to improve the efficiency and quality of installing nuts on long threaded rods.

[0031] When installing the nut 100 on the long threaded rod, the nut is clamped by the nut clamping assembly, the screw 101 is passed through the clearance hole and connected to the nut, the movement of the screw is guided by the screw guide assembly, and then the electric drill is connected to the connecting head. The electric drill outputs power to the power transmission assembly through the connecting head. The power transmission assembly drives the nut clamping assembly to rotate, and then drives the nut to rotate around the long threaded rod, and then the screw is installed on the long threaded rod.

[0032] Specifically, the connector is provided with a slot or a structure that matches with the output shaft of the electric drill, and can be quickly connected with the output shaft of the electric drill by means of a snap connection or a threaded connection, thereby realizing rapid transmission of power.

[0033] During implementation, the nut clamping assembly includes a base 4, a slide groove 5 is provided on the base, and the slide groove is arranged in a regular hexagon. Six clamping blocks 6 are arranged on the base. A slider 7 that can slide with the slide groove is fixedly installed on the lower end of the clamping block. A pin shaft 8 is fixedly installed on the upper end of the clamping block. A guide plate 9 is provided on the base, and the guide plate has six guide grooves 10. The pin shaft can move in the guide groove. The clamping block has a clamping end 11, and the guide plate has a notch that allows the clamping end to move; a locking groove 12 is opened and closed on the guide plate, and a bolt 12 is fixedly installed on the base.

[0034] When clamping the nut, a shutter mechanism is formed by the base, the clamping block and the guide plate, which can clamp nuts of different sizes, and the six clamping blocks can clamp the nut stably. When clamping, the nut is placed between the six clamping blocks, that is, in the notch, and the handle is turned to drive the guide plate to rotate. The guide groove and the pin provided on the guide plate cooperate to drive the clamping block to move along the slide groove, and the clamping block clamps the nut. Then, the butterfly nut is tightened to apply force to the guide plate, so that the guide plate and the base press the clamping block, thereby clamping the nut.

[0035] During implementation, the power transmission assembly includes a driving gear 16 fixedly connected to the connector, a sleeve coaxially arranged with the clearance hole is fixedly installed upward on the base, the driving gear meshes with the driven gear 17, the driven gear is connected to the sleeve through a bearing, and the base is fixedly connected to the driven gear.
