Shaver tool bit frame

Abstract

The invention discloses a shaver tool bit frame which comprises two side portions, a front end portion and a rear end portion. The front end portion bends and extends so as to form a base plate, and then a guide roll installation area is formed. The two ends of the guide roll installation area are respectively provided with clamping mechanisms. The clamping mechanisms and the shaver tool bit frame are integrally formed. Each clamping mechanism comprises an arc-shaped upper baffle and a reversed arc-shaped lower baffle. A first arc-shaped groove is formed in each arc-shaped upper baffle, and a second arc-shaped groove is formed in each reversed arc-shaped lower baffle. The arc-shaped upper baffles and the reversed arc-shaped lower baffles are staggered in the axial direction. The distance between the inner side wall of each upper baffle and the inner side wall of each lower baffle is smaller than the length of an installation shaft. When a guide roll is installed, the installation shaft of the guide roll penetrates through the second arc-shaped grooves, and is supported by the lower baffles. The tail end of the installation shaft is squeezed and stretched into the first arc-shaped grooves of the upper baffles, and therefore the installation shaft can be clamped in the clamping mechanisms in a rolling mode. Due to the fact that the shaver tool bit frame is integrally formed; when installed, the guide roll can be pressed; and the installation shaft can be clamped in the clamping mechanisms with specific structures in the rolling mode, a fabrication process and an assembly process are simplified, and therefore production cost is reduced.

Description

technical field [0001] The invention relates to the field of shaving devices, and more particularly relates to a razor head frame. Background technique [0002] Manual razors include two categories, namely, razors in which the cutter head and the handle are integrated and detachable razors between the cutter head and the handle. Wherein, the former directly fixes the cutter head on the handle of a knife, while the cutter head of the latter is connected with the handle of a knife through an interconnecting part, and the cutter head can be disassembled and replaced. [0003] Generally, the existing shaver head, as disclosed in the patent document CN201456047, includes a frame body, and several positioning blocks are symmetrically arranged on the opposite side walls of the frame body. The positioning blocks are arranged at intervals to form a number of card slots, and the blade unit with a blade is installed in the card slot to realize the shaving function. At the same time, a...

Problems solved by technology

However, the structure of the part used to install the guide roller in the cutter head frame is complex and a detachable outer cover needs to be provided in addition. The manufacturing process of the above-mentioned frame needs to manufacture the frame and the outer cover separately, and the assembly process is also troublesome, resulting in the entire frame Body production costs are too high
