FIG. 4 is a top view of the hand in FIG. 6; FIG. 5 is a top view of FIG. 2; FIG. 6 is a cross-sectional view taken along line C-C of FIG. The position of the inside and the state of the hand shaft and the U-shaped groove in the machine head; Figure 7 shows the two active states of the hand in the handpiece, the N state and the unlock state; Figure 8 shows the hand in the nose. The three active states within the three, the P state - to be driven by the electronic ignition state; Figure 9 is the four active state of the hand in the handpiece, the W state and the electronically completed ignition state. In the figure: 1, the fuselage, 2, the nose, 3, the U-shaped slot inside the nose, 4, pickpocket, 5, 揿 hand shaft, 6, electronic, 7, fire, o, 揿 hand axis.

(5) Specific implementation methods The invention is further described below in conjunction with the drawings. Referring to Figure 1 and Figure 9, in order to ignite the electron (6), the hand (4) must be pressed down to drive the electron (6) to ignite, and the pick (4) is exposed outside the nose (2). Only the E and F faces of the hand (4), and the distance (height) of the G face of the hand (4) to the G face of the handpiece (2) is far less than the distance required for the ignition of the electron (6) ( Height), the electron (6) needs to be pressed a certain distance (height) to ignite. Since the electron (6) is not the subject of the present invention, it will not be explained; the E surface cannot be activated after pressing, and can only be returned without success. After releasing the E surface, the picking hand (4) is pressed back to the original position by the spring force of the electronic (6). To flip the F surface of the pick (4) up 90 degrees, but the distance (radius) from the axis of the hand (0) to the point D of the hand (4) is greater than the axis (0) of the hand. The distance (radius) of the H point of the inner top wall of the nose (2), that is, ₀ D>oH, when the F surface of the pick (4) is turned up, the D point of the pick (4) is the head (2) The H point is blocked, and it cannot be turned up smoothly. Therefore, the pickpocket (4) at this time is already in the locked state, the M state, the pickpocket (4) cannot be started, and has played a safety protection role, reaching the present invention. The purpose of the security lock. In Figure 7, the pick-up (4) is in the unlocked state -N state in the nose (2); the D-plane distance (height) from the E-face of the pick-up (4) to the pick-up (4) The thickness (height) of the top wall G to H of the head (2) is as long as the E point of the pick (4) is pressed, so that the D point of the pick (4) is lower than the head

(2) H point, and press and hold, it will be successfully unlocked. At this time, the D point of the pick (4) is lower than the H point of the head (2), so the H point can no longer block the pick (4). Flip, at this time, the F-face of the pick-up (4) can be flipped up 90 degrees smoothly, in the state of the ignition state of the electronic (6) ignition state. It must be pointed out that these two actions must be consecutively completed and cannot be separated. Pressing the E side of the pickpocket (4), and holding it down, then picking up the hand

(4) The F-face can be turned up 90 degrees smoothly, otherwise it will not work. If the E-face of the pick-up (4) is pressed, it will be loosened, and it will be back by the electronic (6) self-tensioning force. In the original place, it is in a locked state - M state. Unlocking can also be explained as follows: Pressing the E side of the pick (4) down is equivalent to lengthening the distance from the H (0) of the hand axis (0) to the H point of the handpiece (2), and the axis of the hand (0) ) The D point of the pickpocket (4) is the same as a whole, so the distance between them is still the same regardless of the number of presses. Therefore, after pressing the E plane, press and hold, at this time oH>oD, It is possible to smoothly flip the F face up by 90 degrees, so that the pickpocket (4) is in the state of ignition (P) of the electronic (6). In Figure 8, the pick-up (4) is in the head (2) in the state of the electronic (6) ignition state, one P state, at this time, the F-face of the pick-up (4) to the nose (2) The G-plane distance (height) is greater than the distance (height) required for the ignition of the electron (6), so pressing the F-face of the hand (4) can smoothly drive the electron (6). In Figure 9, the hand (4) drives the electron (6) to complete the state after ignition - the W state. After use, release the F-face, the pick-up (4) is turned off by the electron (6)'s own spring force, and the fire head is turned off, and the F-face of the pick-up (4) is turned down 90 degrees and then returned. In the original place, that is, the locked state is an M state, at which time the pickpocket (4) is locked again, cannot be activated, and functions as a security protection to achieve the purpose of the security lock of the present invention.
