[0046] Preferably, if Figure 2 , 9 As shown in Figure 11, the locking mechanism 4 includes a first locking block 41 and a second locking block 42; a first protrusion 411 is provided at the upper end of the first locking block 41, and the first protrusion 411 is snap-fitted with the first groove 22 at the rear end of the magazine 2; a second protrusion 421 is provided at the lower end of the second locking block 42, and the second protrusion 421 is snap-fitted with the second groove 23 at the rear end of the magazine 2, so as to fix the locking mechanism 4 to the second end of the magazine 2; a V-shaped protrusion 412 is provided at the lower end of the first locking block 41, and a V-shaped groove 422 is provided at the upper end of the second locking block 42, and the V-shaped protrusion 412 is fitted with the V-shaped groove 422, and a locking column 423 is provided in the V-shaped groove 422, and the locking column 423 is locked and connected with the locking hole 322 at the second end of the guide rail 32, so as to fix the guide rail 32 with the locking mechanism 4.

[0047] Preferably, if Figures 12 to 14 As shown, the scalp clip 5 is a ring-shaped cantilever structure, one side of the scalp clip 5 is provided with an opening slit 51 matching the cross-sectional shape of the track, and the corresponding side is provided with a notch 52, the guide rail 32 passes through the opening slit 51 and the notch 52 in sequence, and the guide rail 32 does not contact the notch 52, so that the scalp clip 5 can slide on the guide rail 32.

[0048] Preferably, if Figure 2As shown, the first end of the trigger 31 is a trigger head 311, and the second end is a trigger tail 312. A pin hole 115 is provided on the first shell 11, and the pin is provided in the pin hole 115. The trigger 31 is rotatably fixed to the first shell 11 by a pin provided between the trigger head 311 and the trigger tail 312, and the trigger head 311 is inserted into the trigger buckle on the first shell 11.

[0049] Preferably, if Figure 2 As shown, the trigger is an arc-shaped groove (which may be a U-shaped groove) with an opening, and the first end of the trigger 31 is an arc-shaped protrusion. When the trigger 31 is pulled, the arc-shaped protrusion slides into the arc-shaped groove.

[0050] Preferably, if Figure 3 As shown, the positioning windows 27 on both sides of the magazine 2 are correspondingly arranged, the intervals between adjacent positioning windows 27 on the same side are equal, and the positioning windows 27 correspond to the scalp clip 5 on the guide rail 32 .

[0051] The method of using the scalp clip gun of the present invention is as follows:

[0052] When the trigger 31 is pulled, the trigger 31 transmits the force to the trigger 31 and the transmission rack 34 through the rotating shaft. The transmission rack 34 moves horizontally in a straight line. The first transmission tooth 343 of the transmission rack 34 cooperates with the second transmission tooth 351 of the propeller 35 to move the propeller 35 forward. Due to the limit of the transmission rack 34, the stop protrusion 352 of the propeller 35 moves forward one grid (i.e., one positioning window 27), and the scalp clip 5 also moves forward the same distance. Since the scalp clip 5 is cantilevered, it moves along the guide rail 32 at the same time. When it moves to the front end opening portion 321 of the guide rail 32, i.e., the Y-shaped opening end, , the scalp clip 5 is stretched open and maintained at the Y-shaped opening end; when the trigger 31 is released, the transmission rack 34 moves horizontally backward under the action of the tension spring 33, and is locked to the current positioning window 27 due to the stop protrusion 352 of the pusher 35. Due to the special structure of the tooth shape, the pusher 35 moves upward along the positioning window 27, so that the first transmission tooth 343 and the second transmission tooth 351 are separated, and the transmission rack 34 is pulled back to the original position. At the same time, the pusher 35 moves downward under the action of the spring 353, so that the first transmission tooth 343 of the transmission rack 34 matches the second transmission tooth 351 of the pusher 35. When the trigger 31 is pulled again, the pusher 35 moves forward by the distance of the positioning window, and the scalp clip 5 also moves forward by the distance of the positioning window. The scalp clip 5 previously positioned at the Y-shaped opening end of the guide rail 32 is pushed out of the Y-shaped opening end by this movement distance to stop scalp bleeding. At the same time, the second scalp clip 5 is kept at the Y-shaped opening, waiting for the next movement distance to be clamped on the scalp. Repeating the above actions, all scalp clips 5 can be sent out in sequence and delivered to the working position.

[0053] So far, the technical solutions of the present invention have been described in conjunction with the preferred embodiments shown in the accompanying drawings. However, it is easy for those skilled in the art to understand that the protection scope of the present invention is obviously not limited to these specific embodiments. Without departing from the principle of the present invention, those skilled in the art can make equivalent changes or substitutions to the relevant technical features, and the technical solutions after these changes or substitutions will fall within the protection scope of the present invention.
