Referring to fig. 2, the base 110 may be a plate-shaped structure, and the movable base 120 may slide on the base 110 at will, and complete the locking of the product when clamped between the limiting block 130 and the base 110.
In one or more embodiments, a sliding cavity 112 is disposed on a side of the base 110 near the moving seat 120, and the moving seat 120 is at least partially accommodated in the sliding cavity 112 and is capable of sliding in the sliding cavity 112. The sliding cavity 112 may be formed by sinking an end surface of the base 110 near the moving seat 120, or may be formed by surrounding a plurality of side blocks (not shown).
The bottom of the sliding cavity 112 may be recessed away from the center of the sliding cavity 112 to form a sliding groove 114, and the moving seat 120 is slidably matched with the sliding groove 114, so that the moving seat 120 may slide along the sliding groove 114, and further the moving seat 120 moves along a preset track. For example, the sliding grooves 114 may be provided at opposite sides of the sliding chamber 112, whereby the two sliding grooves 114 define a sliding path along which the moving seat 120 slides.
Referring to fig. 3 and 4, the moving seat 120 may include a sliding block 121, an elastic member 122 and a base 123, wherein one end of the elastic member 122 is connected to the sliding block 121, and the other end of the elastic member 122 is connected to the base 123, and the sliding block 121 is at least partially received in the sliding cavity 112 and slidingly cooperates with the sliding groove 114, so that the sliding block 121 slides along the sliding groove 114 to drive the elastic member 122 and the base 123 to move along a predetermined track.
Specifically, the slider 121 may be provided with a first accommodating hole 121a, and the base 123 may be provided with a second accommodating hole (not shown), where one end of the elastic member 122 is accommodated in the first accommodating hole 121a and fixedly connected to the slider 121, and the other end is accommodated in the second accommodating hole and fixedly connected to the base 123. The elastic member 122 may be a spring. By providing the elastic member 122, locking screws for products of different specifications can be facilitated.

When the screw locking fixture 10 is used for locking the product, the push rod 126 is pushed first, so that the movable seat 120 is separated from the limit of the limit block 130. Subsequently, a nut of a predetermined specification is placed in the nut cavity 123b, and the nut is entered into the lamination cavity 123c of a corresponding specification. Then, the product is put in again, the product is fixed in the positioning cavity 123a, the push rod 126 is pushed, the movable seat 120 is moved along the sliding groove 114 and is moved to a position corresponding to the limiting block 130, the movable seat 120 is positioned between the limiting block 130 and the base 110 and is limited, when the movable seat 120 enters between the limiting block 130 and the base 110, the locking seat 150 is inserted between the sliding block 121 and the base 123, and after the product is moved to a preset position, the notch 130a on the limiting block 130, the threaded hole on the product, the nut cavity 123b and the nut in the nut cavity 123b are in a coaxial position. The screw is inserted again and the screw is locked with the nut, and the locking force causes the base 123 to have a tendency to move in a direction approaching the slider 121 during the locking process, and the locking seat 150 gives the base 123a supporting force and prevents the movement tendency of the base 123. After the screw is locked, the push rod 126 is pushed to enable the movable seat 120 to return to the initial position and separate from the limiting block 130, at this time, the locking seat 150 is separated from the base 123 and the sliding block 121, the push rod 126 is pressed down to enable the base 123 to overcome the resistance of the elastic piece 122 and move towards the direction close to the sliding block 121, along with the movement of the base 123, the barrel rod 124 moves upwards relative to the base 123, and the barrel rod 124 supports the locked screw, so that the product is ejected out of the positioning cavity 123a, and the product can be easily taken out.
According to the screw locking clamp 10, the sliding block 121, the elastic piece 122 and the base 123 are arranged on the moving seat 120, the sliding block 121 and the base 123 are connected through the elastic piece 122, the positioning cavity 123a is arranged on the base 123 and is used for accommodating and fixing a product, the nut positioning piece 1232 is arranged at the bottom of the positioning cavity 123a, the nut cavity 123b is arranged in the nut positioning piece 1232 and is used for accommodating and positioning a nut, the barrel rod 124 is further arranged, one end of the barrel rod 124 is fixedly connected to the sliding block 121, the other end of the barrel rod 124 extends into the nut cavity 123b, and when the base 123 moves towards the direction of the sliding block 121, the barrel rod 124 extends into the nut cavity 123b and ejects the product for locking the screw out of the positioning cavity 123a, so that after the screw locking is completed, the base 123 is pressed down, the product can be conveniently identified through the barrel rod 124, the taking procedure time of the product is greatly shortened, and the processing efficiency is improved.
