Currently in the medical field, many instruments are motorized instruments, such as staplers. Staplers are devices used in medicine to replace manual suturing, the main working principle being the detachment or anastomosis of tissue by titanium staples, similar to staplers.

The conventional stapler is driven by power supplied from a battery. Since the stapler is disposable, a non-rechargeable battery or a disposable battery is used. However, in many medical teaching fields, in order to save teaching cost, the same anastomat needs to be repeatedly used to operate on a human body model, and a non-rechargeable battery has limited power and cannot support the time consumed by multiple uses of one anastomat. Therefore, it is necessary to specially equip the teaching stapler with rechargeable batteries, but the number and placement of the rechargeable batteries are different from those of the non-rechargeable batteries, so that during production, molds need to be respectively made for the rechargeable batteries and the battery accommodating devices of the disposable batteries, thereby increasing the production cost. However, if the battery accommodating device is manufactured by using the same mold to obtain the accommodating shell with the same shape and used for accommodating the battery, the accommodating shell is manufactured by necessarily selecting the maximum size of the space occupied by the non-rechargeable battery and the rechargeable battery, so that no matter which kind of battery is accommodated, the accommodating shell has redundant space in the accommodating shell, the accommodating shell is necessarily shaken in subsequent transportation and use, the battery in the accommodating shell moves in the redundant space to cause the battery to be incapable of being fixed, and therefore the battery cannot be stably electrically connected with the outside.
