One end of the scroll spring 97 away from the circular ring 95 is fixed on the inner wall of the first cavity 94. A toothed groove 900 is formed on the surface of the circular ring 95. A linkage plate 96 is connected to the surface of the circular ring 95 through a pin shaft. One side of the linkage plate 96 away from the circular ring 95 is connected to a clamping rod 98 through a pin shaft. One end of the clamping rod 98 away from the linkage plate 96 penetrates through the limiting groove 93, and the clamping rod 98 is slidably connected to the limiting groove 93. The connecting component 9 further includes a releasing member 99. When the fixing column 91 enters the limiting groove 93, the surface of the fixing column 91 will contact the inclined surface of the clamping rod 98. The clamping rod 98 moves away from the center of the limiting groove 93. The linkage plate 96 drives the circular ring 95 to rotate forward, and the scroll spring 97 is wound up. The positions of the clamping groove 92 and the clamping rod 98 are parallel. The scroll spring 97 is released, the circular ring 95 rotates reversely, the linkage plate 96 drives the clamping rod 98 to enter the clamping groove 92, stabilizing the water-cooling head 11 and the main body frame 1. At this time, the mounting seat 12 is parallel to the mounting groove 13 of the main body frame 1, and bolts can be normally fixed without deviation, preventing it from affecting the installation by personnel.

[0023] The releasing member 99 includes a second cavity 990. A gear 991 is rotatably connected to the inner wall of the second cavity 990. The second cavity 990 communicates with the first cavity 94. The gear 991 meshes with the toothed groove 900. A rotating rod 992 is fixed on the top of the gear 991. The top of the rotating rod 992 penetrates through a knob 993, and the knob 993 is fixedly connected to the rotating rod 992. When maintenance needs to be carried out on the water-cooling head 11, the bolts are removed, the knob 993 is rotated, the rotating rod 992 and the gear 991 rotate, the toothed groove 900 drives the circular ring 95 to rotate reversely, the linkage plate 96 pulls the clamping rod 98 away from the clamping groove 92 to release the limit, and at this time, the water-cooling head 11 can be taken out for maintenance.

[0024] One side of the clamping rod 98 close to the fixing column 91 is arranged in an inclined shape. When being contacted, the clamping rod 98 can be moved. A control box 2 is arranged on the inner wall of the main body frame 1. A bracket 3 is fixed on the inner wall of the main body frame 1, which is convenient for charging and discharging tests of the battery pack. The bottom of the main body frame 1 is connected with universal wheels 4. A power connection hole is formed on the surface of the main body frame 1. The universal wheels 4 facilitate movement. The power connection hole is used to pass through the test circuit. A mounting seat 12 is fixed on the surface of the water-cooling head 11. A mounting groove 13 is formed on the surface of the main body frame 1, which is convenient for bolt installation. An inlet pipe 10 is connected to the surface of the water-cooling head 11. One end of the inlet pipe 10 away from the water-cooling head 11 is connected to a water tank 5. Heat dissipation fins 6 are connected to the surface of the water tank 5, which is convenient for heat dissipation.

[0025] During use, the water-cooling head 11 is attached to the surface of the main body frame 1, so that the fixing column 91 enters the limiting groove 93. At this time, the surface of the fixing column 91 will contact the inclined surface of the clamping rod 98. At this time, the clamping rod 98 moves away from the center of the limiting groove 93, driving the ring 95 to rotate forward through the linkage plate 96. At this time, the scroll spring 97 is wound up. When the positions of the clamping groove 92 and the clamping rod 98 are parallel, the scroll spring 97 is released, driving the ring 95 to rotate backward, driving the clamping rod 98 into the clamping groove 92 through the linkage plate 96. The side of the clamping rod 98 away from the inclined surface contacts the inner wall of the clamping groove 92, thus stabilizing the water-cooling head 11 and the main body frame 1. At this time, the mounting seat 12 is parallel to the mounting groove 13 of the main body frame 1, and bolt fixing can be carried out normally without deviation, preventing it from affecting the installation of personnel. When it is necessary to test the battery pack, place the battery pack on the surface of the bracket 3, pass the test circuit through the power connection hole and connect it to the battery pack for testing. At the same time, the operator turns on the cooling pump 7, so that the coolant in the water tank 5 enters the water-cooling head 11 through the water outlet pipe 8 to dissipate heat from the main body frame 1, and at the same time, the coolant is taken out through the water inlet pipe 10 and re-enters the water tank 5 to be dissipated by the heat dissipation fins 6, thereby carrying out the circulating liquid cooling heat dissipation work. When it is necessary to maintain the water-cooling head 11, remove the bolts, rotate the knob 993 to drive the rotating rod 992 and the gear 991 to rotate, drive the ring 95 to rotate backward through the tooth groove 900, and pull the clamping rod 98 away from the clamping groove 92 through the linkage plate 96, thus releasing the limit. At this time, the operator can take out the water-cooling head 11 for maintenance.

However, based on the present invention, some modifications or improvements can be made, which are obvious to those of ordinary skill in the art. Therefore, modifications or improvements made without departing from the spirit and idea of the present invention are within the protection scope of the present invention.
