Fig. 7 is a front view, Fig. 8 is a front view of the main body shown in Fig. 7 removed from the holder, Fig. 9 is a sectional view taken along the line D-D in Fig. 8, and Fig. 10 is a It is an enlarged cross-sectional view taken along the line E-E. In the figure, 1 is the main body, 2 is a switch for an electric motor (not shown) built into the main body 1, 3 is a handle provided on a holder 4 made of aluminum, 5 is a knob bolt,
Reference numeral 7 denotes a spring which supports the holders 4 which are respectively fitted into a plurality of columns 6 set up on the upper surface of the base 8. The handle 3 is slidably displaced by holding the handle 3 and pushing it downward, and when the handle 3 is released, the handle 3 is returned to its original position by tension. 9 is a spindle driven by an electric motor, and the lower end of the spindle 9 is attached to the mount 1 of the main body 1.
4 through a ball bearing 18, and a tip tool 11 is removably fixed to the lower end of the spindle 9 through a nut 10 and a collet 21. 13 is a groove for locking a lock pin 19 formed on the mount 14, and 16 is a spindle hole. The lock pin 19 tightens the nut 10, and when loosening it, the spindle hole 16 and the groove 13 are used as shown in the figure.
It is designed to be inserted into the Furthermore, Natsuto 10
Tighten it, and of course remove it when you don't want to loosen it. 20

る必要があつた。 When the switch 2 is turned on, the spindle 9 directly connected to the shaft 20 of the electric motor is driven to rotate, and the tip tool 11 is rotated. When the handle 3 is pressed downward in FIG. 7, the holder 4 slides on the column 6 and moves downward. The tip tool 11 protrudes from the bottom surface of the base 8 and processes wood etc. by the amount of the protrusion. The tip tool 11 used for this processing is attached to and detached from the spindle 9 using a mount 14 formed of resin on the main body 1.
After fixing the spindle 9 by inserting a lock pin 19 made of steel into the groove 13 formed in the groove 13 and the spindle hole 16 provided in the spindle 9 as shown in FIG. 10, the nut 10 is tightened or loosened using a spanner. was doing. However, with this structure,
The force applied when tightening or loosening the nut 10 is applied to the groove 13 of the mount 14 of the main body 1.
There was a problem that parts could be damaged or deformed, and furthermore, it was dangerous to operate in this condition, so safety measures had to be taken.

できる。 Hereinafter, the lock pin locking device for an electric router according to the present invention will be explained with reference to FIGS. 1 to 6 using an embodiment, and the same parts as the conventional one are designated by the same reference numerals, and the explanation of the structure of the same parts is omitted. Fig. 1 is a front view, Fig. 2 is a front view of the main body shown in Fig. 1, Fig. 3 is a sectional view taken along the line A-A in Fig. 2, and Fig. 4 is a front view of the operating section shown in Fig. 1. , FIG. 5 is a sectional view taken along line B-B in FIG. 4, and FIG. 6 is an enlarged cross-sectional view taken along line CC in FIG. In the figure, the holder 4 is formed to wrap around the outer periphery of a mount 14 that is formed to wrap around the outer periphery of the spindle 9.
A hole 12 and a groove 13 through which a lock pin 19 can be inserted are opened in the mount 14 and the holder 4 in a radial direction centered on the spindle 9 at a position communicating with a spindle hole 16 opened in the spindle 9. Therefore, the lock pin 19 is formed to be able to be inserted through the center of the triple portion of the spindle 9, mount 14, and holder 4. And spindle 9
When tightening and fixing the nut 10 to attach the tip tool 11 to the
3. After aligning the hole 12 with the position, insert the lock pin 19 to rotate the spindle 9, that is, lock pin 1
The rotation of 9 is received by the mount 14 and the hole 12. Therefore, in the past, the lock pin 19 was prevented from rotating by using the groove 1 of the resin mount 14.
3, but in this embodiment, the holder 4 made of aluminum material is used to receive the holder 4, thereby eliminating the possibility of excessive force being applied to the groove of the mount 14.
