the middle shell is arranged in the machine shell and is positioned on the front side of the containing cavity;

the clamping piece is arranged on the middle shell; the clamping piece is provided with an elastically deformable clamping part which extends into the accommodating cavity;

the battery bin is accommodated in the accommodating cavity through the opening; the front end of the battery compartment is provided with a through hole for the clamping part to penetrate through; a buckle opposite to the via hole is convexly arranged on the battery bin, and the buckle comprises a first guide part and a second guide part connected to the rear side of the first guide part; the first guide part and the second guide part are both obliquely faced to the rear end of the battery compartment; a clamping groove which is concave to the rear end of the battery bin is formed at the joint of the first guide part and the second guide part; when the battery compartment moves forwards, the first guide part contacts and drives the clamping part to buckle the clamping groove, or the second guide part contacts and drives the clamping part to separate from the clamping groove;

and the elastic piece is arranged on the middle shell and extends into the accommodating cavity to provide backward elastic acting force for the battery compartment.

2. The remote controller according to claim 1, wherein there are two said fasteners, and two said fasteners are respectively installed on the front and back sides of said battery compartment, and have 180 degree rotational symmetry;

the clamping piece comprises an installation part and two clamping parts which are elastically connected with two ends of the installation part, the installation part is rotatably connected with the middle shell, and the two clamping parts are respectively contacted with the corresponding buckles to move reversely.

3. The remote controller according to claim 1 or 2, wherein the first guide portion has a first front guide surface and a first rear guide surface inclined with respect to the rear end surface of the battery compartment; the first front guide surface and the first rear guide surface form an included angle, the rear ends of the first front guide surface and the first rear guide surface are connected, and the first rear guide surface is positioned on the rear side of the first front guide surface;

the second guide part is provided with a second front guide surface and a second rear guide surface which are inclined relative to the rear end surface of the battery compartment; the second front guide surface and the second rear guide surface form an included angle, the rear ends of the second front guide surface and the second rear guide surface are connected, and the second rear guide surface is positioned on the rear side of the second front guide surface;

the front end of the second front guide surface is in transitional connection with the front end of the first rear guide surface to form the clamping groove.

4. The remote control of claim 3, wherein said first front guide surface and said first rear guide surface are smoothly transitioned; the second front guide surface and the second rear guide surface are in smooth transition connection.

5. The remote control of claim 3, wherein the clasp further comprises a blocking portion;

the blocking part is positioned in front of the first guide part and connected with the first guide part; the blocking part and the first guide part are arranged on two sides of the middle shaft surface of the clamping piece.

6. The remote controller according to claim 5, wherein the blocking portion has a blocking surface and a third guide surface inclined with respect to the rear end surface of the battery compartment, and a first transition surface connecting the blocking surface and the third guide surface;

the third guide surface and the first front guide surface are positioned on the same plane and connected;

the blocking surface protrudes to one side of the third guide surface, which is back to the middle shaft surface of the clamping piece, and is connected with the second rear guide surface through a second transition surface;

the first transition surface, the middle shaft surface of the clamping piece and the second transition surface are parallel to each other.

7. The remote controller according to claim 1 or 2, wherein the elastic member is made of a conductive material;

the middle shell is provided with a circuit board, the rear end of the circuit board is connected with one end of the elastic piece, and the other end of the elastic piece enables the circuit board to be electrically connected with the battery bin when abutting against the battery bin.

8. The remote control of claim 7, wherein said resilient member has a plurality of resilient members arranged on opposite sides of said engaging member.

9. The remote control of claim 1 or 2, wherein the clasp is on a medial axial surface of the battery compartment.

10. The remote controller according to claim 1 or 2, wherein the battery chamber is provided with a fixing seat in a protruding manner; the remote controller also comprises a wear-resistant block, wherein the wear-resistant block is arranged on the fixed seat and exceeds the fixed seat along the thickness direction so as to be abutted against the inner wall of the shell.
