[0027] The technical solutions in the embodiments of the present application will be clearly and completely described below with reference to the drawings in the embodiments of the present application. Obviously, the described embodiments are only part of the embodiments of the present application, rather than all the embodiments.

[0030] The bottom end of the fixed clamp part 21 is installed at the top end of the insulating tube 10 and is fixed through the fastening sleeve 27, and the middle part is a through hole. The movable clamp part 22 is S-shaped, the middle part is embedded in the middle part of the fixed clamp part 21, and the movable clamp part 22 is assembled into a pair of relatively rotatable pliers through the pin shafts 25, and the head part of the fixed clamp part 21 and the head part of the movable clamp part 22 are clamping operation parts of the clamp.

[0031] See Figure 4When working, the clamping feet 28 are located on both sides of the front end boss of the buckle 41, and the head of the movable clamp part 22 pushes the rear end boss of the buckle 41 forward to pass the plug 42 of the insulator cover through the front end boss of the buckle 41, thereby achieving the fastening and installation of the buckle 41.

[0032] See Figure 3 The pushing force of the movable clamp part 22 is provided by the power of the rechargeable battery 33 of the driving unit 30, and the electric operation device is a stepping electric push rod 31, and the head of the push rod 35 is a screw rod, which is connected with the insulating connecting rod 26 through a threaded connector 34.

[0033] The push rod 35, the threaded connector 34 and the insulating connecting rod 26 are coaxially installed in the insulating tube 10.

[0034] The press reset switch 32 at the upper part of the point pressure rubber handle 11 is pressed, the motor inside the electrically driven stepping electric push rod 31 rotates, drives the push rod 35 to reciprocate, generates a forward pushing force, and synchronously drives the insulating connecting rod 26 to reciprocate.

[0035] See Figure 2 The adapter 24 is connected to the upper part of the insulating connecting rod 26 and slides along the inner cavity of the insulating tube 10 under the action of the insulating connecting rod 26.

[0036] The insulating connecting rod 26, the articulated pull rod 23 and the movable clamp part 22 form a planar connecting rod mechanism, which converts the linear reciprocating motion of the push rod 35 into the rotary motion of the movable clamp part, thereby realizing the clamping operation function.

[0044] The single-chip microcomputer monitors the charging and discharging state of the battery through the charging control module and the current sensor, and the BMS can ensure that the battery operates in a safe range, and can pre-announce insufficient power and prevent overcharging and overdischarging, so as to avoid battery thermal runaway and potential fire risk.
