Description

[Detailed description of the invention] The present invention relates to a clipper blade.

In the conventional clipper blade, as shown in FIG. 3, the fixed blade 2 is attached to the clipper housing 9 with a mounting screw 10, and the movable blade 4 is pressed by a pressing spring (not shown) whose base is fixed to the clipper housing 9. The configuration is as follows.

In the conventional example, the pressing spring, movable blade 4, and fixed blade 2 are each attached to the clipper housing 9, so each attachment means is complicated and disassembly and installation is troublesome. There is.

The present invention has been made in view of the above-mentioned drawbacks, and an object of the present invention is to provide a clipper blade that has a simple structure and is easy to replace.

The present invention will be explained below according to the embodiments shown in FIGS. 1 and 2.

The base 1 is made of plastic and has a comb blade 2a at the tip.
A fixed blade 2 having a substantially T-shaped plate shape is placed thereon.

The base 1 includes a substantially rectangular plate-shaped substrate portion 1a that becomes thinner toward the tip, and a pair of protrusions 1c that protrude upward on both sides of the J base 1.
, 1c, a pair of second engaging protrusions 1d, ld protruding from each protrusion 1c in the direction of the comb blade 2a of the fixed blade 2, and a pair of second engaging protrusions 1d, ld protruding in a direction opposite to the protruding direction of the second engaging protrusions 1d. The first engaging protrusion 1b protrudes between the second engaging protrusions 1d.

The fixed blade 2 fits the narrow part of the T hand between the second engagement protrusions 1d and 1d, and the wide part of the T hand between the inclined recesses 3, 3 provided at the tip of the second engagement protrusion 1d and the base plate 1a. It is held on the base 1 by inserting it between the two.

The movable blade 4 has a comb blade 4a, and an engagement hole 5 in which a drive rod (not shown) connected to a drive source (not shown) engages in order to slide on the upper surface of the fixed blade 2, and a comb blade 4a in the vicinity of the comb blade 4a. It has recesses 6, 6 into which the tips of pressing springs, which will be described later, are fitted.

The pressing spring 7 is formed by connecting the spring tips of a pair of torsion coil springs, and is formed by connecting the spring tips of each of the pair of torsion coil springs.
The torsion coil portion 7a, which is the fixed end, is penetrated and locked by the pin 8, which supports both ends, and the tips 7b, 7b of the pressing spring 7 are engaged with the recesses 6, 6 of the movable blade 4, and the rear end of the pressing spring γ is engaged. 1c
This presses the rear end of the fixed blade 2, the narrow part of the T hand.

That is, the pressing spring 7 has the function of pressing and fixing the fixed blade 2 to the base 1 and pressing the movable blade 4 against the fixed blade 2.

With the above configuration, the fixed blade 2 and the movable blade 4 are attached to the base 1 via the pressing spring 7 to constitute one blade block A, and the blade block A is attached to the first engagement protrusion 1b provided on the base 1. into the engagement holes (not shown) provided in the clipper housing (not shown), and fit the elastic plates (not shown) fixed to the clipper housing into the second engagement protrusions 1d and ld of the base 1. and attach it to the clipper housing.

As described above, in the clipper blade of the present invention, the fixed blade, movable blade, and pressing spring are all attached to the base to form a blade block, and the base is attached to the clipper housing at three points. Therefore, each of the above elements is reliably connected, and the pressing spring reliably presses the movable blade, resulting in stable sharpness.Furthermore, the clipper housing can be attached and detached at once, making it easy to clean the blades. ,
It has the effect of being convenient when changing to a block with various functions, and furthermore, since the fixed blade is attached to the base with the assistance of a pressing spring, it is easy to attach the fixed blade to the base. effective.
