Referring to fig. 1-3, the present invention provides a technical solution:
a clutch device applied to a transmission belt of a crochet hook head comprises an elastic fixing part 1, a clutch hook belt part 2 and a clutch hook part 3 which form a three-dimensional structure;
the fixed end of the elastic fixing part 1 is fixedly arranged on the surface of the needle cylinder mounting plate through a compression screw and is used for providing torque force during separation;
one end of the clutch hook belt part 2 is horizontally vertical to the torque end of the elastic fixing part 1, and the other end of the clutch hook belt part 2 is vertically vertical to the torque end of the clutch hook part 3 and is used for clutching a belt;
the hook end of the clutch hook part 3 is hooked with the bottom surface of the needle cylinder mounting plate and used for providing hook force after clutch.
The utility model is arranged on one side of the needle cylinder and penetrates through the belt, when the belt needs to be separated from the needle cylinder, the clutch hook belt part 2 is pressed downwards, so that the whole clutch bends along the elastic fixing part 1 until the clutch hook belt part 2 drives the belt to be stirred onto the clutch wheel of the needle cylinder from the fixing wheel of the needle cylinder. The utility model has simple and practical structure, is safe and does not hurt hands, has low manufacturing cost and is beneficial to market popularization.
Specifically, the elastic fixing portion 1 is composed of a spiral elastic ring 101 and a torsion bar 102, the spiral elastic ring 101 is fixedly arranged on the surface of the mounting plate of the syringe by a compression screw, the terminal end of the torsion bar 102 is connected with the initial end of the spiral elastic ring 101, and the initial end of the torsion bar 102 is horizontally vertical to one end of the clutch hook belt portion 2.
Further, the spiral elastic ring 101 is spiral, and the number of spiral turns is 1. The fixing structure is not only beneficial to fixing the clutch hook belt part 2 on the surface of the needle cylinder mounting plate by utilizing a compression screw, but also enables the ground clearance of the starting end of the torsion bar to be greater than the ground clearance of the terminal end of the torsion bar, and provides a section of buffer height for pressing the clutch hook belt part 2.
Still further, the torsion bar 102 is a V-shaped structure composed of two metal bars of different lengths, the shorter metal bar being horizontally perpendicular to the clutch hook band portion 2, and the longer metal bar being connected to the spiral elastic ring 101.
