[0002] The prior art CN219358992U discloses a clamp locking mechanism for a diamond grinding and polishing machine, including a clamp mounting base. The clamp mounting base is provided with a guide groove for the clamp to slide into and a locking structure for locking the clamp in the guide groove. The locking structure includes a pressing member, a hook, a rocker plate, and a driving member for driving the pressing member to press or reset. There are two rocker plates and two hooks, which correspond one to one. The rocker plate is oscillating on the clamp mounting base. One end of the rocker plate is hinged to the pressing member, and the other end is hinged to the corresponding hook. When the clamp slides from the guide groove to the designated position, the driving member drives the pressing member to move. At this time, the rocker plate pries, thereby driving the hook to hook the clamp onto the inner wall of the guide groove, thereby restricting the movement of the clamp. The two hooks can be pulled at the same time by one driving member.

[0003] The locking structure of the above scheme is relatively complex, which leads to increased production and manufacturing costs. Summary of the Invention

Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0026] like Figure 1-6 As shown, a locking structure for a diamond grinding and polishing machine clamp seat includes: a hinge seat 1, which is disposed on the clamp seat 100 and has a hinge hole 11 thereon; a pull rod 2, the upper end of which is formed with a hinge joint 21 and the lower end is a connecting part 22, on which a hook plate 23 that can lock the clamp to the clamp seat 100 is fixed or integrally disposed; a connecting block 3, the lower part of which is connected to a cylinder 4 that drives its lifting and lowering, the cylinder 4 being directly mounted on the clamp seat 100; and a lever 5, which includes a first straight section 51, a curved section 52, a second straight section 53, and a hinge part 54 formed at the connection between the first straight section 51 and the curved section 52, the hinge part 54 being correspondingly disposed with the hinge hole 11, the first straight section 51 having a first strip hole 511, the second straight section 53 having a second strip hole 531, and the first straight section 51 having a first strip hole 511, the second straight section 53 having a second strip hole 531, the first straight section 51 having a first strip hole 511, the second straight section 53 having a second strip hole 531, the first straight section 51 having a first strip hole 511, the second straight section 53 having a second strip hole 531, the first straight section 51 having a first strip hole 511, the second straight section 53 having a first strip hole 531, the first straight section 52 having a first strip hole 511, the second straight section 53 ... 51 is hinged to the hinge joint 21 through the first strip hole 511, and the second straight section 53 is hinged to the connecting block 3 through the second strip hole 531; two hinge seats 1, two pull rods 2 and two levers 5 are provided, and the two second straight sections 53 are located on both sides of the connecting block 3; the connecting block 3 is provided with a receiving groove 31 for accommodating the second straight section 53, and the connecting block 3 is provided with a through hole 32 corresponding to the receiving groove 31, and a shaft is passed through between the through hole 32 and the second strip hole 531; the hinge joint 21 is provided with a mounting groove 211 for accommodating the first straight section 51, and the hinge joint 21 is provided with a through hole 212 corresponding to the mounting groove 211, and a shaft is also passed through between the through hole 212 and the first strip hole 511; the hinge part 54 is configured as a hinge hole 11; the clamp seat 100 is provided with a mounting plate 6 for supporting the cylinder 4.

[0027] By adopting the above technical solution, compared with the prior art, this utility model improves the installation structure of the cylinder 4 and the structure of the lever 5 and the pull rod 2. Specifically, the cylinder 4 directly drives the connecting block 3 to rise and fall, and the cylinder 4 can be directly or only mounted on the clamp seat 100 via the mounting plate 6, greatly simplifying and optimizing the structure. The structure of the lever 5 and the pull rod 2 is optimized to match the design scheme of the cylinder 4 directly driving the mounting plate 6. Thus, when the piston rod of the cylinder 4 moves downward, the pull rod 2 can move upward, thereby causing the hook plate 23 to move upward to lock the clamp onto the clamp seat 100. The first strip hole 511 and the second strip hole 531 allow the shaft to move between them, so that when the lever 5 swings through the hinge part 54, the first straight section 51 and the second straight section 53 can smoothly achieve the swinging action, thereby enabling the pull rod 2 to move up and down when the connecting block 3 rises and falls. Furthermore, by improving the structure of the hinge seat 1, the pull rod 2 is located on the outside of the hinge seat 1 away from the hinge hole 11, which greatly reduces the manufacturing cost of the hinge seat 1.
