[0008] A fixing block is fixedly connected to the inner ring surface of the main body of the pin, and a nut is inserted into the inner ring surface of the fixing block for limiting. A knob handle is fixedly connected to the side surface of the extension threaded rod.

[0009] A grip is installed on the side surface of the knob handle, a metal support plate is fitted onto the outer ring surface of the extension threaded rod, and an anti-slip sleeve is fitted onto the outer ring surface of the pin body.

[0010] The present invention further illustrates that the side surface of the grip is provided with a snap-fit ​​opening, and the snap-fit ​​opening extends through the grip.

[0011] The above technical solution features a snap-fit ​​opening that runs through the handle, making it convenient for users to use and carry the handle.

[0012] The present invention further explains that the inner ring surface of the pin body is provided with a movable limiting opening, and the movable limiting opening and the extended threaded rod are structurally compatible.

[0013] The above technical solution, with its movable limiting opening that fits the structure between the extension threaded rod and the pin body, allows users to easily adjust the pin body.

[0014] This utility model further illustrates that the nut is connected between the fixing block and the main body of the pin, and the fixing block is arranged around the nut as the center point.

[0015] Using the above technical solution, the fixing block arranged around the nut as the center point can facilitate the user to stably install the nut on the pin body.

[0016] This utility model further illustrates that a push head is installed on the side surface of the extended threaded rod, and the push head and the limiting plate are structurally compatible.

[0017] The above technical solution, which features a push head that fits structurally with the limiting plate, facilitates the user's use and push of the pin body.

[0018] This utility model further illustrates that the outer ring surface of the metal support plate is fitted with snap-fit ​​gaskets, and there are multiple snap-fit ​​gaskets.

[0019] The above technical solution uses multiple snap-fit ​​pads, which facilitate the user's use of the metal support plate for protective support.

[0020] Compared with the prior art, the beneficial effects achieved by this utility model are:

[0021] This utility model provides a pin shaft that prevents it from coming off the bolt. Through the coordinated use of the pin shaft body, metal support plate, handle, snap-fit ​​opening, knob handle, push head, limit plate, fixing block, anti-slip sleeve, extension threaded rod, nut, movable limit opening, and snap-fit ​​washer, the user can efficiently and effectively use the pin shaft without it coming off the bolt. When installing the pin shaft, the user inserts the pin shaft body into the desired installation position, then inserts the pin shaft body and metal support plate. Next, the user turns the knob handle, which rotates the extension threaded rod. The nut limits the push head, allowing the user to push the metal support plate back. The pin shaft body limits the opening of the metal support plate. The snap-fit ​​washer facilitates efficient and secure snap-fit ​​of the pin shaft, meeting the user's need for efficient and secure snap-fit ​​operation.

[0022] This utility model provides a pin shaft that prevents it from falling off. By setting a knob handle, a grip fixedly connected to the side surface of the knob handle, and multiple snap-fit ​​openings through the grip, the user can easily use and carry the pin shaft with their fingers, thus meeting the user's need for convenient use and carrying.
