[0018] To make the technical means, creative features, objectives and effects of this utility model easier to understand, the utility model will be further described below.

[0019] like Figures 1 to 4 As shown, a special disassembly tool for an automatic throttle actuator clutch includes a wrench head 1 and a wrench lever 2 that cooperates with the wrench head 1. The wrench head 1 includes a cylindrical cavity 11 and a number of sets of claws 12 that are equidistantly distributed along the inner sidewall of the cylindrical cavity 11.

[0020] The special disassembly tool for the automatic throttle actuator clutch is designed according to the unique structural shape of the product clutch. It uses chucks set on the steps to disassemble the automatic throttle actuator clutch. It is not only simple and easy to operate, but also avoids the safety hazards caused by the use of improper tools during installation and disassembly.

[0021] like Figure 1 As shown, the cylindrical cavity 11 uses a cylindrical structure that is adapted to match the shape of the clutch of the automatic throttle actuator, and can fit tightly and seamlessly with the upper cover of the clutch, increasing the force-bearing area.

[0022] The utility model discloses a step 13 is dug in the cylindrical cavity, when being vertically installed on the upper portion of the clutch, plays the fixed connection effect to the upper cover, facilitates subsequent rotation and sends the force.

[0023] As Figure 2 The four clamping claws 12 designed on the upper portion of the step 13 can ensure that the four recesses of the clutch are all fixed in butt joint during installation, compared with the situation that the needle-nose pliers and the tiger forceps used in the production site can only be fixed on two recesses, the disassembling tool can effectively increase the stress area, and meanwhile ensure that the butt joint is tight during use, so that the clutch and the personal safety are not damaged due to slipping during rotation and disassembly.

[0024] As Figure 2 The four clamping claws 12 are provided with four groups, which are used to ensure that the four recesses of the clutch are all fixed in butt joint during installation.

[0025] As Figure 3 And Figure 4 The wrench rod 2 is penetrated in the cylindrical cavity 11, and the design of the wrench rod 2 is that when the hand directly contacts the cylindrical cavity 11 to rotate and send the force, the friction is insufficient due to the cylindrical structure design, and the upper cover of the clutch cannot be unscrewed due to insufficient force during use, one wrench rod 2 is penetrated in the cylindrical cavity 11, after the wrench head 1 is fixed on the clutch, both hands hold the two sides of the wrench rod 2, press the cylindrical cavity 11 vertically downward to ensure that the four clamping claws 12 are tightly connected with the recesses on the clutch, and then rotate counterclockwise to disassemble the upper cover of the clutch.

[0026] The above shows and describes the basic principle, main features and advantages of the utility model. It should be understood by those skilled in the art that the utility model is not limited to the above-mentioned embodiments, and the above-mentioned embodiments and descriptions in the specification are only the principles of the utility model, and various changes and improvements can be made without departing from the spirit and scope of the utility model, and these changes and improvements all fall within the scope of the utility model. The scope of protection of the utility model is defined by the appended claims and their equivalents.
