- Jul 03, 2019-

The carpet film applicator is a rotary retractable film applicator which, when used, effectively includes a rotary telescopic structure thereof, and the rotary telescopic structure thereof effectively includes a rotating body, a telescopic body, a fixed shaft and an elastic member. The body has a receiving groove, and the front end surface of the rotating body is formed with a pushing surface and a positioning groove. The expansion body has a middle through hole, and the outer circumference of the telescopic body is provided with a pushing surface and a positioning groove to realize the extension and retraction of the expansion body. The boss has a limiting structure in the through hole in the telescopic body, and the fixing shaft passes through the telescopic body, the rotating body and is fixed on the casing, and the elastic component is sleeved on the fixed shaft, and the two ends respectively abut against the limit The position structure and the fixed shaft head, so that when the user operates the applicator, the tongue cutter can be extended and retracted by rotating the rotating body, thereby avoiding providing a cover at the outer end of the casing, thereby facilitating The user's operation.

The carpet film applicator includes a housing having a notch at the front end when in use, and an application portion disposed at the front end of the housing, wherein the inside of the front end of the housing is also effectively formed with a rotation restricting portion for restricting the rotation of the application portion, and the shell The rear end side of the body is formed with an operation port, and the film applicator further comprises a rotary telescopic structure disposed at the rear end of the housing. The rotary telescopic structure comprises: a rotating body, a telescopic body, a fixed shaft and an elastic element, and the rear end of the rotating body exposes the operation port, and rotates The body further has a receiving cavity, and the front end of the receiving cavity has an opening for the expansion body, the fixing shaft and the elastic member, and the front end surface of the rotating body is further formed with a pushing surface and a positioning groove.
