[0029] The present invention will now be described in further detail with reference to the accompanying drawings. These drawings are simplified schematic diagrams that illustrate the basic structure of the present invention only in a schematic manner. Therefore, they only show components relevant to the present invention, and directions and references (e.g., up, down, left, right, etc.) may be used solely to facilitate the description of features in the drawings. The following detailed description is therefore not to be taken in a limiting sense, and the scope of the claimed subject matter is defined solely by the appended claims and their equivalents.

[0030] Example 1:

[0031] like Figures 1-4 As shown, a nail magazine assembly swing head angle indication mechanism includes:

[0032] The swing head 1 is arranged between the nail magazine assembly 4 and the gun body assembly 5. The swing head 1 is fixed to the rear end of the nail magazine assembly 4 and is hinged to the front end of the gun body assembly 5;

[0033] The driving member 2 is axially disposed inside the gun body assembly 5 and has a front end eccentrically connected to the swing head 1 to drive the swing head 1 to turn;

[0034] The indicator 3 includes a pointer fixed to the rear end of the driving member 2 and a transparent dial 304 provided on the housing 502 of the gun body assembly 5. The scale on the dial 304 corresponds to the rotation angle of the swing head 1, and its "0" position is located at the center of the dial 304. When the pointer is at the "0" position of the dial 304, the swing head 1 has not turned. It is coaxial with the gun body assembly 5. When the driving member 2 moves backward and drives the swing head 1 to turn to the side where the driving member 2 is located, the pointer moves backward to indicate the backward movement distance of the driving member 2, thereby obtaining the current direction and angle of the swing head 1. When the driving member 2 moves forward and drives the swing head 1 to turn to the other side, the pointer moves forward to indicate the forward movement distance of the driving member 2, thereby obtaining the current direction and angle of the swing head 1.

[0035] In some examples, the driving member 2 includes a push rod 201 connected to the swing head 1, a driving rod 202 for pushing and pulling the push rod 201, a sleeve 203 fixed at the front end of the driving rod 202, and a connecting block 204 for connecting the sleeve 203 and the push rod 201; the driving rod 202 is electrically controlled, and the control unit inside the gun body assembly 5 controls the driving rod 202 to move forward and backward. The driving rod 202 drives the push rod 201 to move forward and backward through the sleeve 203 and the connecting block 204, and the push rod 201 drives the swing head 1 to turn.

[0036] In some examples, there are two driving rods 202 , which are symmetrically arranged and fixed to the rear end of the sleeve 203 . The sleeve 203 is provided with a socket for inserting the driving rod 202 , and the pointer is fixed to one of the driving rods 202 .

[0037] In some examples, a fixing seat 501 is provided inside the gun body assembly 5 , and a sliding groove 5011 is provided on the fixing seat 501 for the driving rod 202 to slide. The sliding groove 5011 can guide the forward and backward movement of the driving rod 202 .

[0038] In some examples, the pointer includes a clamping portion 301 for clamping the driving rod 202 , an indicating portion 302 for cooperating with the scale plate 304 , and a connecting portion 303 for connecting the clamping portion 301 and the indicating portion 302 , wherein the connecting portion 303 is arc-shaped.

[0039] In some examples, the rear end of the driving rod 202 fixed to the pointer is recessed to form a contraction section 2021 for clamping by the clamping portion 301, and two limiting steps 2022 are formed at both ends of the contraction section 2021 to limit the clamping portion 301. The clamping portion 301 is provided with a plurality of spaced apart clamping jaws 3011. In this embodiment, three clamping jaws 3011 are provided, and the two clamping jaws 3011 at both ends are provided with slots.

[0040] In some examples, the shell 502 is provided with a receiving groove 5021 for accommodating the dial 304, and the dial 304 has protruding plug-in portions 3041 at both ends. The groove wall of the receiving groove 5021 is provided with a plug-in groove 5023 for the plug-in portion 3041 to be inserted. The plug-in portion 3041 is inserted into the plug-in groove 5023 to fix the dial 304 on the shell 502.

[0041] In some examples, the shell 502 is provided with an installation cavity 5022 for accommodating the indicator part 302. The installation cavity 5022 is located below the accommodating groove 5021 and the two are connected to each other. When the driving rod 202 moves back and forth, it can drive the indicator part 302 to move back and forth in the installation cavity 5022.

[0042] In some examples, an electric laparoscopic stapler includes the above-mentioned staple cartridge assembly 4 and the swing head 1 angle indicating mechanism.

[0043] Based on the above-mentioned ideal embodiment of the present invention, and in accordance with the above description, relevant personnel can make various changes and modifications without departing from the technical scope of the present invention. The technical scope of the present invention is not limited to the content of the specification, but must be determined according to the scope of the claims.
