Specific embodiments

[0027] In order to enable those skilled in the art to better understand the solution of this application, the technical solutions in the embodiments of this application will be clearly and completely described below in conjunction with the accompanying drawings in the embodiments of this application. Obviously, the described embodiments are only a part of the embodiments of this application, rather than all the embodiments. Based on the embodiments in this application, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of this application.

[0028] The present utility model provides a measuring jig for a staple cartridge to solve the problems that the positions of the staple groove and the cutter groove in the existing staple cartridge cannot be quickly and accurately detected, the detection efficiency is low, and it may affect subsequent use.

[0029] For the convenience of understanding, the specific process in the embodiments of this application will be described below. Please refer to Figures 1 to 4 , A measuring jig for a staple cartridge in the embodiments of this application includes a staple cartridge 1, a base 2, an ejector pin 3, an insert piece 4, an elastic component 5 and a positioning part 6; the staple cartridge 1 includes a seat body 10, and a plurality of staple grooves 11 and cutter grooves 12 are provided on the back surface of the seat body 10, and a limiting part 13 is provided at the end of the seat body 10; the base 2 is arranged below the staple cartridge 1, and the ejector pin 3 and the insert piece 4 are arranged at one end of the upper surface of the base 2; the elastic component 5 is arranged opposite to the ejector pin 3 and the insert piece 4 on the base 2; the positioning part 6 is installed in the base 2 and is located between the elastic component 5, the ejector pin 3 and the insert piece 4.

[0030] The measuring fixture for the anvil of the present utility model. After manually pressing the front end of the limiting part 13 against the elastic component 5 and compressing the elastic component 5, the elastic component 5 gives a reaction force to the limiting part 13, so that the rear end of the limiting part 13 is positioned by the positioning part 6. Then, visually check whether the ejector pin 3 and the insert piece 4 are adapted to the knife groove 12 and the nail groove 11, so that it can be conveniently and accurately detected whether the positions of the nail groove and the knife groove on the anvil 1 are qualified, improving the detection efficiency and meeting the use requirements.

[0031] Based on Figure 2 , in this embodiment, the insert piece 4 is arranged parallel to the length direction of the base 2 at one end of the base 2; the ejector pins 3 are divided into two groups, and the two groups of ejector pins 3 are symmetrically distributed at both ends of the insert piece 4. Among them, each group of ejector pins includes three ejector pins 3 arranged in parallel. The positions of the above-mentioned ejector pins 3 and the blade 4 are the same as those of the standard product, so that it can be quickly determined whether the positions of the knife groove and the needle groove on the anvil 1 are qualified through the positions of the ejector pins 3 and the insert piece 4.

[0032] Based on Figure 5 and Figure 6 , the elastic component 5 includes a fixed block 50 inserted into the base 2. The fixed block 50 is vertically installed on the base 2. A compression spring 51 is arranged on the fixed block 50 perpendicular to it. The compression spring 51 is linearly distributed with the limiting part 13; the other end of the compression spring 51 is connected with a push block 52. After manually pressing the limiting part 13 against the push block 52, the compression spring 51 is compressed. Then, the limiting part 13 is manually released, and the compression spring 51 gives a reaction force to the push block 52, so that the push block 52 pushes the rear end of the limiting part 13 towards the positioning part 6 until the positioning part 6 positions the rear end of the limiting part 13.

[0033] In addition, an arc-shaped groove 520 adapted to the front end of the limiting part 6 is arranged on the push block 52, so that the push block 52 and the limiting part 6 can be better matched, thus facilitating the push block 52 to push the limiting part 6 to the positioning part 6 for positioning.

[0034] Based on Figures 5 to 6 , in this embodiment, the positioning part 6 includes a base block 60 arranged on the base 2. A convex positioning block 61 for positioning the rear end of the limiting part 13 is arranged at one end of the base block 60 close to the insert piece 4 and the ejector pin 3. When the compression spring 51 gives a reaction force to the push block 52, the push block 52 drives the limiting part 13 and the whole anvil 1 to move backward until the rear end of the limiting part 13 abuts against the positioning block 61. At this time, the position limiting of the anvil 1 is completed, and at this time, it can be observed whether the knife groove 12 and the needle groove 11 on the anvil 1 are vertically corresponding and adapted to the ejector pin 3 and the insert piece 4 on the base 2.

[0035] In addition, based on Figure 5 , in order to ensure the accuracy of the movement of the anvil seat 1, a guiding mechanism for driving the anvil seat 1 to be guided is further provided. The guiding mechanism includes positioning seats 70 arranged at both ends of the base block 60 near one side of the compression spring. Guide openings 71 are formed in the two positioning seats 70, and a guide shaft 72 penetrating through the push block 52 is arranged between the two guide openings 71.

[0036] When the anvil seat 1 moves left and right, the guide shaft 72 can move left and right in the two guide openings 71, so as to ensure the accuracy of the position of the anvil seat 1 during movement.

[0037] Based on Figures 1 to 6 , the working process of this measuring fixture is described as follows:

[0038] First, manually place the limiting part 13 into the base block 60, and then press the front end of the limiting part 13 against the push block 52. When the push block 52 moves forward, the compression spring 51 is driven to be compressed. Then, after the person releases the hand, the compression spring 51 drives the limiting part 13 to move backward through the push block 52. When the limiting part 13 moves to a certain position, the rear end of the limiting part 13 is positioned by the positioning block 61. At this time, the entire position of the anvil seat 1 has been positioned.

[0039] Then, the operator visually checks whether the ejector pin 3 and the insert 4 fall into the corresponding cutter grooves 12 and nail grooves 11 of the anvil seat 1, so that it can be conveniently and accurately observed whether the anvil seat is a good product, and the detection is convenient and the detection efficiency is high.

[0040] As described above, the above embodiments are only used to illustrate the technical solutions of the present application, rather than to limit them; although the present application has been described in detail with reference to the foregoing embodiments, those of ordinary skill in the art should understand that: they can still modify the technical solutions recorded in the foregoing embodiments, or perform equivalent replacements on some of the technical features; and these modifications or replacements do not make the essence of the corresponding technical solutions deviate from the spirit and scope of the technical solutions of the embodiments of the present application.
