Description of the invention (3) Adjacent to a wheel (30), continuous teeth (32) are provided on the peripheral surface, and inner # = a right-shaped polygonal sleeve (34), such as Hexagonal and dodecagonal are: (3: or the shape of a bolt. The ratchet (30) is placed outside the circular hole of the body: so it can rotate in the circular hole. A c-shaped buckle (35) , Buckled in the groove (241) provided by the two to prevent the ratchet from coming out. The fighter ♦ a catch (40 h is housed in the perforation (25), the inner end is also two (: 4 (Γ) Ϊtooth (42), 啮 engages with the ratchet tooth (32). The latching surface 27 is in contact with the abutment surface (26), and the other side is in contact with the i 傀 洗 二 ί The latch can be provided with a beveled surface (44) on the side that contacts the beveled surface. A beveled surface (27) has a better fit, but the beveled surface is not necessarily C2q) The ring (45) covers the ring / 29 provided on the outer periphery of the body (20), and at the same time covers the outer periphery of the latching member (40), and the card holder is maintained at a normal state. Ratchet :: The sleeve is known as Erhai sleeve. 0) Use the Japanese "second picture" with a wrench (4

Km is inserted into the insertion hole (22) of the body (20), and is connected to a screw connection element with the two spines. By turning the wrench (48), the ▼ sleeve is actuated to drive the screwing element. ^ The third and fourth pictures show the operating state of the sleeve. In the third picture, the second movement i; (2〇), the ratchet (30) is applied by the screw connection element. The piece (40) will be subject to the ratchet's linkage ^ The right crime is against the abutting surface (26), and when the latching piece (40) abuts against the straight abutting surface (26), it will not move outwards so the latching Pieces of ratchet salivation will not come off. With this murmur, you can bring: 521025 V. Description of the invention (4) The ratchet rotates clockwise, and the drive screw technology does not have 47 ^ pieces 0 Conversely, please refer to the fourth figure. If w, the ratchet (30) When the main body (20) is rotated by the screwing element = the needle direction and the card holder (40) is linked to the left position; when the bevel surface (27) is rotated in the direction of two or two hours, the bevel card (40) ) Move to the left to engage it. Therefore, the body is counter-clockwise :: eve of the day: Li ’㈤ Li Li is connected with the ratchet. Temple's parallel operation of the method of turning the ratchet wheel and the screw in the fourth picture can be performed by, after, the elastic ring = middle, the state of the force applied by the ratchet to push the latch is restored, and the card engine is pushed up. The piece returns to the third figure 2.
