[0028] The first step is to pull the T-block 18 during use, so that the top of the T-block 18 slides upward inside the groove 17, and at the same time, the T-block 18 moves upward to pull the top of the telescopic rod 19, so that the telescopic rod 19 is stretched by force. After the T-block 18 is pulled, the T-block 18 is out of contact with the positioning port inside the groove 17, and the T-block 18 is pulled to deflect the T-block 18 to one side. At the same time, the T-block 18 drives the rotating seat 21 to rotate inside the second set of plates 15, so that the T-block 18 opens the inside of the groove 17, and by pulling the first set of plates 11 and the second set of plates 15, the first set of plates 11 and the second set of plates 11 are connected. 5, move the two first plates 11 respectively, connect the first plate 11 and the second plate 15 to the surface of the wrench body 1, rotate the first plate 11 and the second plate 15, rotate the first plate 11 and the second plate 15 at both ends of the connecting plate 16 respectively, pull the T-block 18, let the T-block 18 pull the telescopic rod 19 to extend and retract, push the T-block 18 to rotate into the inside of the groove 17, under the reverse force of the telescopic rod 19, the telescopic rod 19 applies a downward pulling force to the T-block 18, let the T-block 18 move, and the bottom end of the T-block 18 fits with the positioning port inside the groove 17.

[0029] In the second step, the user holds the end of the wrench body 1, rotates the two first plates 11, and rotates the first plates 11 on one side of the wrench body 1. The user pulls the top of the second strap 14 to pass through the inside of the buckle 13. Since the first strap 12 and the second strap 14 are both made of flexible materials, the second strap 14 is passed through the inside of the buckle 13, and the top of the second strap 14 is pulled in the opposite direction. The second strap 14 slides inside the buckle 13, and the buckle 13 applies tension to the first strap 12, so that the first strap 12 The second strap 14 is gradually stretched under force, so that the inner sides of the first strap 12 and the second strap 14 fit the back of the user's palm. After the first strap 12 and the second strap 14 are stretched to a certain extent, the top of the second strap 14 is pressed to make the Velcro 22 installed on the inner side of the second strap 14 fit the surface of the second strap 14, and the position of the second strap 14 is fixed by the Velcro 22.
