摘要： Disclosed are a clamping mechanism and an electric tool. The clamping mechanism includes a main body (1), a locking cap (2), a spring chuck (3) and an outer sleeve (5) which is sleeved on a periphery of the locking cap and is configured to drive the locking cap to rotate, wherein the spring chuck (3) includes at least two spring claws (32) which are circumferentially arranged to form a clamping claw hole (33); the locking cap (2) is connected with the main body (1), and the locking cap is able to move in a direction close to the main body, so that the spring claws (32) are close to each other under a pressing action of an inner wall of the locking cap to achieve clamping, or move in a direction away from the main body, so that the spring claws are loosened; a ring piece (4) is arranged at an end, close to the main body, of the locking cap (2), and an elastic piece (6) is arranged between the ring piece (4) and the locking cap (2); a first groove (52) is arranged on an inner wall of the outer sleeve (5), and a cam block (44) cooperating with the first groove is arranged on the ring piece; and when the cam block (44) is rotated into the first groove (52), the ring piece (4) cooperates with the main body under an action of the elastic piece to limit a rotation of the locking cap relative to the main body in a direction of the loosening of the spring claws in a clamping state of the spring claws, and when the cam block is moved out of the first groove, the ring piece is disengaged from the main body. The locking of the spring claws may be achieved by limiting the rotation of the locking cap relative to the main body by the ring piece arranged between the locking cap and the main body.

摘要： A dustproof structure of a grinding tool holder (20), which comprises a shaft portion (21) and a counterweight portion (22) connected to one end of the shaft portion (21). The counterweight portion (22) comprises an eccentric block (23) connected to the shaft portion (21), at least one bearing (24) mounted in the eccentric block (23), a dustproof ring (25), and a grinding member assembling head (26) assembled with the bearing (24). The eccentric block (23) is formed with an assembly port (233) for disposing the bearing (24) and the dustproof ring (25), the dustproof ring (25) is located on a side of the bearing (24) facing the grinding member assembling head (26), and formed with a first continuous concave-convex structure (251) on a side away from the bearing (24), the grinding member assembling head (26) is formed with a second continuous concave-convex structure (261) on a side facing the dustproof ring (25), the first and second continuous concave-convex structures (251 and 261) match with each other and define dust blocking dots (271).
