As shown in fig. 1, 2 and 3, the present embodiment discloses a fastener installation tool, which includes a handle 1 and a connection member 2, wherein the handle 1 includes a first hinge portion 11, an insertion portion 12 and a holding portion 13, two ends of the insertion portion 12 are respectively connected to the first hinge portion 11 and the holding portion 13, one end of the connection member 2 is hinged to the first hinge portion 11, the other end of the connection member 2 is detachably connected to a bolt, the insertion portion 12 is sleeved with a gasket and a nut, and the gasket and the nut are both connected to the bolt through the first hinge portion 11 and the insertion portion 12.
When the fastener mounting tool is used, firstly, the nut and the gaskets are sequentially sleeved on the inserting part 12 through the connecting part 2 and the first hinge part 11, and the connecting part 2 is connected with a screw rod in a bolt; then the fastener is installed and fixed on the installation hole of the structure, an operator holds the holding part 13 of the handle 1 by hands, firstly, the head part of the bolt penetrates through the installation hole from the outside to the inside of the structure, then, the whole bolt and the connecting part 2 extend into the structure through the installation hole, part of the gasket is adjusted in a swinging way, so that the gasket can extend through the mounting hole into the interior of the structure, after which the operator's force is applied to the grip portion 13 and pulled outwards, so that the washer will abut against the inside of the mounting hole, the head of the bolt will abut against the washer and be located inside the mounting hole, the nut located on the outside will be connected to the screw of the bolt through the insertion portion 12, the first hinge portion 11 and the connecting member 2, so that the washer and the nut will abut against the outside of the mounting hole and after the fastener has been mounted, the connecting part 2 and the screw in the bolt are detached from each other. Thereby realize fixing the fastener installation on the locating hole of structure, realize the installation between two structures fixed, also can realize that the fastener installation is structurally connected fixedly with other structures.
The fastener mounting tool of this embodiment for the fastener need not to install from the inside of structure, can directly install the fastener to the structure from the outside of structure, and the erection joint is very convenient. Be connected with the bolt through adapting unit 2, gasket and nut will overlap on inserting portion 12 for holding handle 1 and just can driving bolt and gasket removal and punch a hole to the inboard of structural mounting hole, just realize fixing the fastener installation on the mounting hole of structure through rotatory nut in the outside of mounting hole, thereby it is all very convenient to realize installation, dismantlement and change. The gasket sleeved on the fastener mounting tool needs to pass through the mounting hole and abut against the inner side of the mounting hole, so that the shape of the gasket is not circular but strip-shaped, and the gasket can pass through the mounting hole and abut against the inner side of the mounting hole when being adjusted in a swinging mode.
In the present embodiment, the length of the cross-sectional shape of each of the first hinge portion 11 and the insertion portion 12 is smaller than the outer diameter of the bolt. The inner diameter of the nut is greater than the length of the sectional shapes of the first hinge part 11 and the insertion part 12 so that the nut can be sleeved on the first hinge part 11 and the insertion part 12 and can move, and the inner diameter of the nut is connected with the outer diameter of the bolt, thereby realizing the installation of the fastener.
The connecting member 2 includes a second hinge portion 22 and a connecting portion 21, one end of the second hinge portion 22 is hinged to the first hinge portion 11, the connecting portion 21 is connected to the other end of the second hinge portion 22, and an external thread 211 is formed on the outer circumferential surface of the connecting portion 21. The connecting part 21 is connected with the screw rod in the bolt through the external thread 211, so that the connecting part 2 is very convenient to install and detach with the bolt, and the connecting part is simple in structure and convenient to process and manufacture.
