[0026] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0027] Example

[0028] like Figures 1-6 As shown, a staple cartridge remover is used to remove the staple cartridge 5 from a staple cartridge holder 4. It includes a main board 1, a staple removal part 2 located at the head of the main board 1, and a gripping part 3 located at the tail of the main board 1. The main board 1, staple removal part 2, and gripping part 3 are integrally molded by injection molding, making them simple to manufacture and low in cost. The staple removal part 2 cooperates with the front end 51 of the staple cartridge and includes an abutment part 21 and baffles 22. The abutment part 21 is located below the main board 1, and the side of the abutment part 21 closest to the main board 1 is an arc-shaped surface that abuts against the bottom surface of the front end 51 of the staple cartridge. Two baffles 22 connected to the main board 1 are provided on both sides of the abutment part 21. The two baffles 22 are arranged opposite each other and inclined to the main board 1, gradually tilting outwards along the direction from the abutment part 21 to the main board 1, allowing the front end 51 of the staple cartridge to easily fit into the staple removal part 21.

[0029] In the above structure, such as Figure 5 As shown, the length of the contact part 21 is less than the length of the front end 51 of the staple cartridge protruding from the staple cartridge seat 4, so as to avoid the contact part 21 colliding with the staple cartridge seat 4.

[0030] like Figure 1 , 4As shown, the abutment part 21 is provided with at least one opening 23 arranged along the width direction of the abutment part 21. In the embodiment, two openings 23 are provided and symmetrically arranged along the width direction of the abutment part 21. The central interval part between the two openings 23 is the main abutting part cooperating with the front end 51 of the nail cartridge, which can reduce the contact area between the abutment part 21 and the front end 51 of the nail cartridge, thereby reducing the friction.

[0031] In addition, as shown in Figure 1 、 4 , the nail taking part 2 further comprises a stop part 24 arranged at one end of the abutment part 21 close to the holding part 3 and arranged perpendicularly to the main plate 1 and extending from the bottom surface of the main plate 1 to the bottom surface of the abutment part 21. The two baffle plates 22 are fixedly connected with the main plate 1, the abutment part 21 and the stop part 24 to form a disassembly cavity accommodating the front end 51 of the nail cartridge and limiting the movement of the front end 51 of the nail cartridge during disassembly, so that the disassembly is more smooth. When using the nail extractor, due to the cooperation of the nail taking part 2 covered by the main plate 1 and the front end 51 of the nail cartridge, the stop part 24 prompts the front end 51 of the nail cartridge to be sleeved in place, prompting the operator to operate the holding part 3 to lift upward to disassemble the nail cartridge, thereby improving the operation convenience.

[0032] Among them, as shown in Figures 1-3 、5, the holding part 3 comprises two baffle plates 31 arranged on both sides of the main plate 1 and a reinforcing baffle 32 arranged between the two baffle plates 31, the baffle plates 31 are connected with the baffle plates 22 on the same side, and the end of the baffle plates 31 close to the nail taking part 2 is transitionally connected with the baffle plates 22; since the baffle plates 22 are arranged obliquely and the baffle plates 31 are arranged perpendicularly, the transitionally connection makes the outer surface smooth and beautiful, and is convenient for forming. The reinforcing baffle 32 is connected with the stop part 24 to improve the strength of the holding part 3 and the whole nail extractor and avoid breaking during disassembly.

[0033] As shown in Figure 2 、 5 , in order to facilitate holding, the lower sides of the two baffle plates 31 and the lower side of the reinforcing baffle 32 coincide and are both S-shaped arcs.

[0034] The working principle of the utility model is as follows: in use, the front end 51 of the nail cartridge is sleeved into the disassembly cavity, the bottom surface of the front end 51 of the nail cartridge abuts on the abutment part 21, and then the holding part 3 is held by hand and lifted upward in the direction away from the nail cartridge seat 4, so that the nail cartridge 5 is separated from the nail cartridge seat 4. The utility model adopts the nail extractor to disassemble the nail cartridge, does not need to directly contact with the nail cartridge, can avoid slipping during disassembly, further extends the force arm through the holding part, reduces the force required for disassembly, improves the disassembly convenience, and makes the disassembly of the nail cartridge more convenient and fast.
