The invention relates to the technical field of machines, in particular to a hold-wrapping type clamping groove structure. The hold-wrapping type clamping groove structure comprises a hold-wrapping type clamping groove. According to the hold-wrapping type clamping groove, an arc-shaped hole is formed in a plate, and the two ends of the arc-shaped hole and the edge of the plate communicate to form a notch. The notch is splayed as a whole, and separation parts are formed between the two ends of the splayed notch in the plate and the two ends of the arc-shaped hole. Telescopic spring pins are arranged at the ends of the two separation parts between the arc-shaped hole and the notch. Each telescopic spring pin is formed in the manner that one end of a sleeve is fixed to the end of the corresponding separation part of the plate, the sleeve is arranged at one end of a pin in a nested manner after a spring is arranged in the sleeve, and the other end of the pin penetrates the end face of the other end of the sleeve. Compared with the prior art, welding is not needed when all the parts are assembled, mounting is easy, environmental pollution is reduced, and manpower and material resources are saved; and the structure is reliable, demounting is convenient, and the dismounted parts can be recycled.
