[0018] The technical solutions in the embodiments of the present invention are described clearly and completely below. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of them. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0019] See also Figures 1 to 4 The utility model embodiment includes: a jig for stud detection, which includes a base 1, a push plate 2 is arranged on the base 1, two push rods 3 are horizontally arranged at one end of the push plate 2, a cylinder 4 is horizontally arranged outside the other end of the push plate 2, a piston rod 5 of the cylinder 4 is fixedly connected to the other end of the push plate 2, and a horizontally inclined waist-shaped hole 6 is respectively arranged on the two push rods 3, a roller 7 that can move in the waist-shaped hole 6 is vertically arranged in the waist-shaped hole 6, a connecting shaft 8 is vertically arranged on the roller 7, a movable slider 9 is respectively arranged on the two push rods 3, the connecting shaft 8 is inserted into the slider 9, a stud fixing block 10 is respectively fixed on the two sliders 9, and an arc-shaped circular hole 11 is respectively arranged at one end of the two stud fixing blocks 10, and the arc-shaped circular holes 11 on the two stud fixing blocks 10 are arranged relatively.

[0020] Preferably, the two push rods 3 are parallel to each other, and the push rod 3 is parallel to the piston rod 5 of the cylinder 4. A baffle 16 is arranged above the push rod 3.

[0021] Preferably, the lower end of the roller 7 is hemispherical to facilitate horizontal movement of the roller.

[0022] Preferably, the lower end of the roller 7 is located on the base 1 .

[0023] Preferably, a stopper 12 is vertically provided at one end of the base 1 , a spring 13 is horizontally provided on the inner side of the push plate 2 , one end of the spring 13 is fixed on the inner side of the push plate 2 , and the other end of the spring 13 points to the stopper 12 .

[0024] Preferably, two guide bars 14 are provided on the base 1, and the two push rods 3 are respectively located outside the two guide bars 14, and the two guide bars 14 are parallel to the two push rods 3. The guide bars 14 guide and limit the horizontal movement of the push rods 3.

[0025] When the stud detection jig of the utility model is used, the stud 15 to be detected is placed in the arc-shaped circular hole 11 on the two stud fixing blocks 10, and the piston rod 5 of the cylinder 4 pushes the push plate 2 and the two push rods 3 to move forward, and the spring 13 plays a buffering role in the movement of the push plate 2. When the two push rods 3 move forward, the horizontally inclined waist-shaped hole 6 pushes the roller 7 to move (the two waist-shaped holes 6 are arranged in a trumpet shape). The more the two push rods 3 move forward, the closer the distance between the two rollers 7 is. The two rollers 7 also drive the connecting shaft 8 and the two stud fixing blocks 10 to approach, so that the arc-shaped circular holes 11 on the two stud fixing blocks 10 are close to clamp the stud 15 to be detected, so that the stud 15 to be detected remains stable, and then the thread detection of the stud 15 can be carried out. On the contrary, when the piston rod 5 of the cylinder 4 is withdrawn, the two stud fixing blocks 10 are separated to release the stud 15. The stud 15 can be fixed and released quickly and easily, thereby realizing high-efficiency detection of the stud.
