The utility model discloses the purpose: in order to overcome the defects existing in the prior art, the utility model provides a fastening bolt.
In order to achieve the above purpose, the utility model provides a following technical scheme: the utility model provides a fastening bolt, includes the bolt head and sets up the screw rod at the bolt head lower extreme, its characterized in that: the bolt head is provided with a concave cavity, a sliding block is detachably mounted in the concave cavity, a cross groove is formed in the bottom of the concave cavity, a straight groove is formed in the surface of the sliding block, grooves are formed in two sides of the sliding block, a rotating block is mounted in the grooves, a rotating shaft is arranged on the rotating block, one end of the rotating shaft penetrates through the sliding block and is located on the surface of the sliding block, a torsional spring is mounted in the groove in the rotating shaft, the inner side of the concave cavity corresponds to the groove and is provided with a second groove, a second rotating block is mounted in the second groove and is provided with a second rotating shaft, one end of the second rotating shaft penetrates through the inner wall of the second groove and is located on the surface of the bolt head, and the torsional spring is mounted in the second groove in the second rotating shaft
Through taking above-mentioned technical scheme, the start turning block that inserts the cavity with the slider can get into the recess with the bolt head contact in, the second turning block gets into in the second recess with the slider contact, the in-process of cavity is gone into to the slider card, turning block and second turning block can pop out because of the effect of torsional spring, the turning block gets into in the second recess, the second turning block gets into in the recess, can realize taking out the slider from the cavity at the in-process rotation axis of going out with the slider, this structure flexibility is high, install the bolt sword that realizes supplying different models in the bolt head through the slider dismantlement and insert and carry out the bolt fastening, it is more convenient to use.
The utility model discloses the further scheme does: the slider anterior segment is equipped with the lug, be equipped with in the cavity with lug complex cooperation groove.
By adopting the technical scheme, the sliding block is more stable in the concave cavity.
The utility model discloses the further scheme does: the rear section of the sliding block is provided with a handle.
By adopting the technical scheme, the sliding block is convenient to push and pull.
The utility model discloses the further scheme does: the turning block is crescent in shape, and the second turning block is triangular in shape.
By adopting the technical scheme, the processing is easy, and the use is convenient.
The utility model discloses an intentional effect: the sliding block is detachably arranged in the bolt head, so that bolt cutters of different types can be inserted into the sliding block to fix the bolt, and the sliding block is convenient to use.
