[0014] Technical effects and advantages of the utility model:

[0015] 1. By setting a pop-up device, compared with the prior art, the hook body is hidden in the handle body, and can be freely retracted or popped out as needed. By pressing the upper cap to apply pressure, the tooth angle of the gear presses down the key teeth of the spline, and then the key teeth are guided to circulate in and out of the key slot, so as to achieve the effect of the hook body popping out and harvesting in the handle, avoiding the hook body from accidentally injuring the user when not in use, and solving the safety hazards of the hook when not in use;

[0016] 2. By setting up a needle changing mechanism, compared with the prior art, the crochet hook is fixed by a limit block, the clamping block and the limit block are clamped to reinforce the limit of the crochet hook body, and the syringe protects the crochet hook to be in a straight state. At the same time, it ensures that the operation of the pop-up mechanism does not cause the crochet hook body to rotate, thereby achieving the effect of using different crochet hooks for different usage scenarios.
