[0026] like Figure 1 and2 As shown, a unitized segmented locking strip comprises a unit support 1, a screw 2, a locking block 3, a stopper 4 and a slider 5. The stopper 4 consists of two pieces and is respectively fixed at the two ends of the unit support 1. The screw 2 is rotatably installed between the two stoppers 4. The locking block 3 is sleeved on the screw 2. A threaded hole A is provided on the slider 5. The screw 2 is screwed into the slider 5. The locking block 3 is lifted by sliding the slider 5. A connecting rod 6 and B connecting rod 7 are respectively fixed at both ends of the screw 2. The two stoppers 4 are both located between the A connecting rod 6 and the B connecting rod 7. A hexagonal hole is provided on the end face of the A connecting rod 6. The shape of the B connecting rod 7 is adapted to the hexagonal hole. A plurality of locking strips can be connected end to end to achieve the purpose of extending the working length of the locking strip, so that the designer can choose the number according to actual needs to meet the requirements of product design, breaking the limitation of the size and style of the locking strip, so that the product design can be carried out flexibly.

[0027] In this embodiment, if Figure 1 , 2 As shown in , 4 and 5, there are two sliders 5, the threaded holes on the two sliders 5 have opposite rotation directions, the screw 2 is a bidirectional screw 2, the two sliders 5 are respectively screwed on the corresponding rotation direction sections of the screw 2, the locking block 3 is clamped between the two sliders 5, and the contact surface between the locking block 3 and the slider 5 is an inclined surface, so that both sides of the locking block 3 are subjected to extrusion pressure at the same time, the force is even, and the structure is stable.

[0028] In this embodiment, if Figure 1 , 3 As shown in Figures 6, a threaded hole B is provided on the unit support 1, and a locking screw 8 is installed in the threaded hole B. The locking screw 8 is screwed on the block 4, and the top diameter of the thread on the screw rod 2 is larger than the diameter of the hole on the block 4 for accommodating the screw rod 2, so as to limit the screw rod 2 between the two blocks 4 to prevent the screw rod 2 from slipping due to the axial force, causing the locking block 3 to shift and the locking block 3 to be misaligned with the locking position.

[0029] In this embodiment, if Figure 1 , 3 As shown in Figures 5 and 6, a slide groove 9 is opened on the unit support 1, and the stopper 4 is fixed in the slide groove 9. A limit platform 10 is fixed on the inner wall of the groove of the slide groove 9. The limit platform 10 extends along the opening direction of the slide groove 9. A boss 11 is fixed on the surface of the locking block 3 close to the inner wall of the slide groove 9. The boss 11 is used to limit the rising height of the locking block 3 to prevent the locking block 3 from falling off from the unit support 1.

[0030] In this embodiment, if Figure 3 As shown, a through hole B is also provided on the unit support 1, and the through hole B is located between the two stoppers 4. Bolts are installed in the through hole B, and the unit support 1 can be firmly fixed to the housing of the board through the bolts.
